Slight problem with removeInstance

I have a form with repeating subform. The coding I have used for the button 'Add subform' is;

 topmostSubform.ContinuationSheet.ButtonAddSheet::click - (JavaScript, client)
ContinuationSheet.instanceManager.addInstance(1);
ButtonReset.presence = "hidden";
ButtonSaveAs.presence = "hidden";
ButtonPrint.presence = "hidden";
ButtonAddSheet.presence = "hidden";

When you press the reset button, it is supposed not only to reset all of the form data, but also reset the counter of subform to 0. The coding that I use for this is;

 topmostSubform.ContinuationSheet.ButtonReset::mouseUp - (JavaScript, client)
xfa.host.resetData();
while (ContinuationSheet.instanceManager.count > 0)
{
    ContinuationSheet.instanceManager.removeInstance (1);
}

Everything works as expected, for the most part. The only problem I encounter is that the buttons in the original subform remain hidden. I tried a lot of different scripts to try to make them see the upward, but nothing helped. Any help would be much appreciated.

Yes like I said it was just a quick idea. The code should be more based on audit for the last instance and then display but not displaying not if this isn't the last instance.

Then why are you hiding the buttons instead of just let them float after repeating subforms? You could have buttons in their own subform that lives inside the cast a subform, but outside the repeated instances so that it always shows upward at the end.

Ah, I think I got it:

If (this.parent.instanceIndex == this.parent.instanceManager.count - 1) {}

This.Presence = "visible";

}

else {}

This.Presence = 'hidden ';

}

You must subtract one from the County, because it is 1-based, but the index is 0-based.

Tested and it seems to work ok. You may need to play with the 'parents' (this.parent.parent... etc.) depending on how buried the subform and hold the keys. If you leave them in a subform, and then you could put this code in the subform that contains the buttons instead of on the buttons themselves.

Oh and I put that on the layout event: loan.

  • Errors/problems with my brand-new Equium A200 15I (including video material)

    Hello

    I am treated to a new computer laptop last Saturday and only had for about 3 and a half days so far but I noticed a few things that I wasn't sure were errors/defects or if it was simply because its news, like the fact that sometimes I type with the keyboard and some letters do not appear on the screen , I think it's probably more to do with me not type or support pretty strongly on the keys rather than anything else, his is not so much now... the touchpad becomes a bit sticky too and he thinks I want to scroll up and down when I move the cursor does not scroll sometimes but I managed to make it work I think that most laptops have glitches like that and no doubt I could help fix it in calibrating the pad (?) touch I did have time to consider the issue and yet if... There are a few other things well and more disturbing than this morning I got an error of video material, so now im a little just worried or suspicious that it may be a real fault with him and would like to know if it is the case, if its something I can fix eventually (im no expert especially with the material, but I can always try to download and installation of updates / corrections and this kind of thing so she could solve the problems).

    The main thing that concerns me more, is that this morning a message suddenly come to the screen, warning me that there was an error in video material, last night, I clicked on a button, I think for load more information. and I took this perforated cap of it: -.

    http://img528.imageshack.us/img528/724/errorscreencapcw1.jpg

    I thought it may be useful to view the actual complete message rather try everything and paste the info., ok to be honest I've not noticed it allow you to copy to the Clipboard, but good (oops lol).

    I know there is a topic on a similar error, but I didn't want end-to-end on this discussion because I assume that it should be for this mistake of people who will be discussed, mine may be slightly different, I don't know... I followed the instructions given in this discussion and I checked the Device Manager and no material defects are appearing, btw it is said in the Manager of peripheral devices, graphics cards, it's a Mobile Intel 945 GM Express Chipset Family, I'm sure that all laptops A200 15I have the same card, but I thought I would just make it clear that. Incase that wasn't the right thing to check I also checked under "Audio, video and game controllers" (as the error says it was a video hardware error) where it lists the only as being "Realtek High Definition" Audio and I checked the properties, both under properties it says that the device works properly, without signs of defects...

    The thing is, I had read somewhere online that there is a problem with the graphics or video cards. I had read that they can be glitchy and sometimes break after a year. I also asked my father about it and we looked at it as a graphics card Intel that came with this laptop, which it is, and we counted that the Intel chips is as reliable as any other brand really... so I don't think there should be a problem, well that is there I have until September next for repair prior to the expiration of the warranty!

    What surprises or sort of worry, however, is that the error message was only introduced to me this morning. It dates from error, as having occurred at 19:53. I use it at night last, and infact, I went to take a shower and I put the laptop down before you go take a shower at around 19:35, I assumed that its ok just close the lid and it would automatically go into hibernate mode or something similar (?) im wondering if that had something to do with it as I 19:53 would have been about when I came back and lifted the lid/screen again to use the laptop again... I can only assume, given the time, he cites, is what caused the failure?

    It gives me the option to "update driver software" and "hardware change analysis" in the Device Manager, can I run both, or one of those who maybe? is this a common problem? should I worry at all etc...

    Any help is very appreciated, if more info. Please let me know and ill clarify what I can. Also in terms of whats installed, I have quite a few programs, for graphics, I have an old version of Paint Shop Pro, which I installed it yesterday morning, it seems to install fine, it is Jasc Paint Shop Pro 7, I have also some programs of converter (for files vid, 3GP and other things), scan antivirus AVG, Spybot Search & Destory DBPowerAmp, FTP Commander, Quicktime and Real Player, pretty basic stuff like that, nothing, just my old photos and vid files I transferred from my old laptop XP to it, in my documents... I don't have all the Senior Games motorized or complicated or anything else like that installed. Also at that time, indicates the video hardware error message, everything that was in progress when I got the cover down (or before putting the lid down) would have been Windows Live Messenger (although I'm pretty sure that I registered before putting the lid down) and an IE window , im pretty sure that's it, I was not working on anything just check the ' net...

    There are other things I noticed as I thought that maybe I should mention (?), something I've noticed he's doing is the screen goes blank and then back very quickly, a lot. I already asked about it a day or so there at that time, I realized he was only doing that before loading the "Windows needs your permission to continue" window/message, who apparently its supposed to do and something to with the computer to switch to display the normal desktop to the secure desktop, I kind of understand lol.
    So I think that's not something to worry about but I noticed during the lastday, that the screen seems to do it more, goes blank then back again, even if the authorization message does not appear.

    For example, this morning, when I first put on and am went to check out my home page, I clicked on a link at the bottom of the page or anywhere where to load another page into the site and display deleted for a while before coming back a second later with the requested page. Is this normal too? or an associated Vista glitch, or is it possible that there may be a small problem with the monitor? Incase of im guessing it can be more than one thing in Vista, but I thought I would ask here, I decided to not pay for any extra insurance/warranty extension because I am very careful with my items and take care of them and so I'm being careful to try to spot defects early, while they may be repairable under the basic warranty and what-not...

    Another thing I noticed is that start with, when I pressed on and kept the 'FN' key, a variety of icons, black and white appeared on the screen that told me what F button (s) to use to make certain adjustments, there still is that when I try right now, but at other times, it does not show icons , no matter how long I hold down the "fn". That didn't matter because I can tell by the symbols on the keyboard press what buttons but its just inconsistent, is there a reason why sometimes the row of icons on the screen will appear when I press and hold the "FN" key and other times it doesn't show at all?

    Also sometimes if I move the slider to the right to the top of the screen, these icons loading as they always seem to be located at the top of the screen, but sometimes it's a problem, if im trying to click on something else and one of these icons rises instead... I'm sure that you can disable this option in sort , but I'd be worried that the icons do not always show when I press and hold the right Button (?) just try to be careful!

    I think that this post is long enough and I don't see what else I could possibly add to help, so I'll leave this here. I don't want to sound too paranoid, but thought it is better to talk about this kind of things incase someone recognizes these defects/errors and can recommend a way fast to resolve potential problems before they can develop into what whether it is worse... Thank you very much in advance for any help on any of these issues!

    (mods let me know if im wrong to include so many things in a subject, I fact kind of this quickly and I apologize if im breaking any rules, I don't want to, if possible please break this into a few different themes or I can do it, although ill be at work frm 2-21:00 today so maybe not back and able to check here until Thursday morning (October 4))

    Hey Isla

    Your message is really very, very long. I think it's too long to read twice ;) s

    . Regarding your questions on this laptop well. Looks like you have installed many applications and 3 third party programs. In such cases, it s not easy to say if these problems are software or hardware related. But I guess that its software.

    I checked your screenshot pic, but I've never seen this error message. But it looks like something wrong with the graphics driver. The message says something, live events of kernel
    The core services are required by other parts of the operating system as for example graphics card driver.

    In this case I recommend updating the graphics driver. According to you, this message an Intel GPU. So you can see the Intel page for the driver for the graphics chip compatible.

    With regard to the key issue of the FN;
    The Toshiba FlashCard utility controls the key features of the FN. I read in this forum that this application does not smoothly run and in some cases it causes some issues. The new update should solve the problems. You should check the Toshiba driver page. The utility of FlashCard is a part of the Toshiba value added package.

    So finally a tip more:
    You should always check the updates of Vista on the Microsoft page. This operating system is not perfect and Microsoft releases hotfixes and patches very often

    I hope that it would help a little.

    If necessary just ask for more information :)

    After you have installed Windows 8 and install all the drivers that I got from the site Web: Lenovo's laptop can no longer play any games. I have more option open of AMD Vision options or options "Switchable Graphics" as they do not appear in the menu when I right click on the desktop.

When I tried to start one of my games, "Killing Floor" it actually caused my cell phone restart.

    Anyone have similar problems with their Windows 8 pc or have a solution?

    Well, I finally found the problem. I discovered that the graphics driver that I had on the Lenovo site have actually NOT installed us. When I ran the Catalyst Install Manager, the Manager showed global progress bar, but it did not install anything. That was pretty weird.

    When I ran the driver Catalyst install listed in the Chinese link that was given to me in this thread.

  • Serious problem with CPU 'maximum frequency.

    Hello

    I have a problem with my W510.

    I think that this problem has been around since I bought it, or at least for a month or two after I bought it.

    When I plug the power in, or out, it almost always affects maximum frequency of the processor, as seen in the Windows 7 resource monitor, as well as a program called CPU - Z which shows in fact the current speed of the base.

    When things work correctly, the basic speed is slightly more than 3,000 Mhz.

    However, this speed changes whenever I plug the power inside or outside.

    Usually, it changes for the worse when I plug IN power!

    Often, to plug in, the speed drops to about 1 000 Mhz. Then I Plug - and the speed goes back to 3 000 Mhz. Rebranchez_ the - 2 500 Mhz. out Plug - rest on 2 500 Mhz. Plug in French - 1 500 Mhz. out Plug - 2 500 Mhz. Plug in French - 3 000 Mhz. get out - 3,000 Mhz, etc.. Every once in a while, it even drops to 300 Mhz.

    It seems to be arbitrary and random. Sometimes, it takes me 10, 15 and even 20 times connect the power out and back in to run to 3,000 Mhz.

    The machine is new, there is no fan noise, and anyway, the changes are directly correlated to plug and power in and out and that they never occur themselves - is certainly not overheating or something like that.

    Also, I don't think it's a problem with the power itself, as happens to me in different countries and different places, and in any place if I try to re - plug power enough times - it will eventually be resolved (so of course that there is enough power).

    Is there someone who knows this problem? Any suggestions?

    Thank you

    I found that Throttlestop help me with my own problem speedstep. Speed moves much to light use because of speedstep, but when I use a cpu benchmark to load four hearts they set to max speed and do not move. You can give it a try.

    Good afternoon!

    OK, I have a problem with the NI 6356 acquisition card, right now that I can capture 1 million samples per second, but after the card purchase made a break between 5-7seconds (I guess that is download the information). I want to have in 1 minute, 60 millions of data. My question: is possible for acquisition card configuration captures 60 millions of data in 1 minute?

    Thank you for the attention!

  • Problem with my new HP Pavilion TS 23-F202IN

    I don't know what the right forum? I checked that this reading All in One is only printers or also for all in a desktop PC?

    I just unboxed it today and now the first problem I faced...

    The keyboard and the wireless mouse do not connected possible fault in the USB receiver that displays no lights when it is connected to the computer... I tried to connect to all the PORTs and the receiver receives no LED light on it so is not conenct to the mouse and the keyboard, even if I keep the button connect, supported on the mouse and the keyboard. The mouse lights are turned on but it does not sync with my PC... I tried to call the HP support center here in INDIA that is not 24 hours, even if they announce it comes 24 hours support... no one answered it because their working time is from 09:00 to 18:00 so sick!

    Then I went to the HP site and followed the link to support that asked me my HP product number and serial number and then there was a link to cat technical support when I went through the cat asked the Executive he tried to solve problems and then when there probly came to a conclusion when he said he would send me a new mouse and receiver it asked me my address at the hearing, I am of the India he said that he will transfer the Chat to an Indian executive support, who came to ask me the same questions, then he told me it is a consumer product, so I need to talk to voice Support team and I could not help on the CHAT! How irritating is that... I have a printer HP ever made a problem with it... and this system has a value of 64 990 /-INR which isn't a small amount and it is the kind according to the sale, I get...

    Is he one of the support here for the response team and address this issue?

    There is also a cat Hillarious records I have if someone wants to read... I'll upload the picturesque images my serial number and address.


    Im a developer of Windows applications

    OK after almost 10 calls back to the HP Helpline, Station of Service HP, HP support line... Finally, I got a new keyboard, mouse and Receiver USB keyboard doenst look alike as it came with my system then obviously, it's just another keyboard HP wireless which is brought... they were just trying to buy time by saying that the keyboard is not available and other stuffs... slightly bad experience but finally the problem was solved...

    My only comments to HP India support would be

    (1) CHECK THE QUALITY OF THE PRODUCT THAT YOU SHIP BEFORE YOU SHIP TO THE CUSTOMER)
    (2) if one of the devices are dead on arrival, take the question on a priority support and fix before 48 hours.
    (3) notify your tracking service center and update the client on their case instead of them calling you 10 times.

    Thank you.

  • Problem with window painted and scrollbars when editing (LabVIEW 8.0.1)

    I'm under LabVIEW 8.0.1 in Windows XP SP3.  For my main VI, I came across a strange problem about 5 months ago.  The front window - both in edit mode and run mode - arrested repaint itself on the right side which is no longer visible when you scroll from top to bottom, but also visible overlapping Windows.  Coinciding with the repaint problem, both bars scroll search disabled grey arrows and no boxes in the bars that you can click and drag to scroll the window.  The scroll bars work still partially if you pass the mouse over it and roll the mouse wheel but does not work by clicking and dragging.

    The façade has a lot of controls and indicators, including containers of tab control and is greater in the horizontal directions and vertical so the two scroll bars must be active.  But I deleted everything in the Panel before and everything in the schema and the problem persists.  If the problem is not directly related to a control/led display.

    I saved the simple VI to this problem (using a line of large text and a high box rounded to test), and then created a new VI and copied the two elements at the new VI.  This new VI didn't paint it and the problem of the scroll bar.  The two screws are slightly different in the memory usage and the revision number (bad is review 1785 and the good is revision 3), but otherwise the two screws are identical.  I have attached two screws at this announcement.  When you first open the bad VI, you will see the scroll bars disabled while the good VI has active scroll bars.  To replicate the repaint problem, scroll the window up and down with your mouse wheel.  If it's good when you first open the VI, click on another window, then click on the window of VI and try again the mouse wheel.  This by clicking sur-loin-and-return always causes the problem of repaint for me.  I tried the screw on two different computers, both running Windows XP SP3 and LabVIEW 8.0.1 with identical results.

    Here's what I discovered simple troubleshooting with the screws:

    always off scroll bars

    * repaint the problem in the main window for larger then 680 pixels of window widths

    * repaint the problem in the menu bar of the main window for widths of more than 646 pixels

    * entire window becomes disabled than 1348 pixels window width

    * can paint window minimize and restore, but only repaints only once

    * scrollbar boxes sometimes flicker in the display, but then disappear

    * Scroll left and right hovering mouse over the bar and horizontal scroll by using the mouse wheel

    I found something similar on this forum (thread: problem with refresh of façade)-it could be linked to the CAR on the Panel being offset internally.  I don't have access to LabVIEW 8.5 or later and do not plan to upgrade - I have not tried the trial version, as this user has done.  I could try to copy and paste my set of the block for a new VI diagram but the VI is so important I'm afraid something would break, plus I don't want to do it again in a few months.  The problem seemed to occur after a certain number of stops (or revision number).  I save copies of backup often and when the problem first happened, I was able to go to a previous version, make the missing changes and save it without any problem, but this only delayed the problem and he came later.  It is therefore perhaps the revision number.  It seems not related to a change or a particular addition in the front panel and the graph.

    The attached picture shows the repaint problems and scroll bar in bad VI.

    This raises a question I have - if this problem is a bug has been fixed in 8.5 and later, is it possible to apply bug fixes for older versions?  Or what I need to pay for an update fix these bugs?

    Seems that something got corrupted with this VI. Things to copy on a cool VI and things should be OK.

    See also this recent report of a similar problem.

  • Problem with the executable files

    Hello all, I need a help from you...

    I use LV 2009 SP1 Professional Development Suite on Windows Seven and I have a problem with the executable files, a problem that I have ever found with other versions of LV (8.x, for example) and I'm a little surprised...

    In the attachment you will find an example of what I mean.

    There are two base screws, the main one (prova) and a Subvi (provasubvi). The main vi launches the Subvi and the Subvi simply create a chart. As you can see on the screws works fine, without any kind of problem.

    I also created the exe file, without specifying that no particular option... and 'magic' of the application does not work as I want. In particular, it seems that the Subvi is running, but the front panel will not be accessible.

    I also try to play with the Subvi construction structure and options, but nothing change.

    Did you ever solve something like that?... I would say that I thank you in advance for any suggestion...

    Andrea

    Hello andrea,.

    Looking at your project I've heard that you do not include the Subvi during the build of the project. SO I slightly modified. Please find the attachments.

    Thank you and best regards,

  • What is the problem with my files, they don't move, copy or delete? #@?!!

    ..... It is not as easy as you think, either! I am not a novice, but I can't understand how to solve this problem! If I try to move the copy or rename them, Windows XP said 'Impossible. Access denied. Even the disk is not full or write protected and the file is not in use."  Well NO, the hard disk is NOT write protected and far from complete.  No other files in "My Documents", or if otherwise, give me problems. In addition, the files themselves are not protected in writing! They don't have ANY special attributes (IE. 'Read only' and 'Hidden' are NOT defined). Needless to say, I did not define all attributes on them myself, they are not in a shared folder, and I am the administrator of my own computer. When I restarted the computer the next day, it changes nothing! The problem with these particular files remained!

    I was able to move, rename, or delete only with UNLOCKER. But it's not my problem. My problem is when I try to burn any program I use, burns keep in check the end and I keep losing DVD - R, one after the other! I understood the reason for the failures of engraving is because of this problem of reading / writing weird with the files!  WINDOWS XP created this write protect it somehow, because he wasn't on the original files! However, this limited access status is invisible! There is no set special attributes on these files!

    They are just media files, I downloaded, as well as text files (FIVE files different, slightly different formats, ALL from different sources!). They have been downloaded to FIVE different subfolders created in 'My Documents'. And it's not just the affected media files. It's all the files that are in the same folders (ie. txt, jpg) (even if I can at least open the jpg, while I can't read multimedia files).  I've never had this problem with any other similar files downloaded in the same folder. These files are NOT protected by copyright, OR infected by viruses, AND I do not have the virus on my system. (I stopped Kaspersky, my virus program, but it made no difference. "So there was no lock file). Yet, I can play is no longer the files (so that I could before the etc..). VLC says "cannot open the file", WMP says similar. I created a new folder in My Documents, moved to the new folder with UNLOCKER, it made no difference! Same problem! Even using UNLOCKER to transfer them to the desktop, not in any folder in itself does not change a thing! Here is another beauty: software "UnlockIT" says "the file is not locked by any conducted! I have to be to imagine...

    ... This whole thing really made me realize how Microsoft Windows helps my carpal syndrome problem...

    Hey PieterVO,

    I've seen this in a few other threads before. Although I don't have a FixIt for you, I have a few discussions to look over.
    I would like you to try to take possession of the individual files that you work with and try again. I didn't see the error codes listed above, so if you get the error codes, please report it to their.
    See Kieron June 9 Post and post Stickywulf November 14 in the second thread I listed above.
    Give those a try and let us know the results. I hope this helps. Thank you!

    my1402 has a slight flashingred with the letter E, but nothing will not print I was told to go to addremove programs and uninstall, but my printer is not on the list of programs

    Hi gjayand welcome to the Forums of HP.

    I see that you are having problems printing.  I would try to help.

    I recommend you to perform a power reset.  Unplug the power cord from the printer and the power outlet, then wait 60 seconds. After 60 seconds, plug back in the printer. Make sure that you connect the printer directly to a wall outlet. Make sure to bypass any surge protector or power bar.

    I suggest you then following the steps in this document on lights blinking.

    Good luck and please let me know the results of your troubleshooting operations. Thanks for posting on the HP Forums!

    Hello

    Having too many CD/DVD programs can cause strange problems, especially if they're loading of parts of
    themselves at the start because they will be competing for resources. This does not mean that this issue has been
    caused by those, however, it's a possibility depending on which and how many you have installed.

    You have disk problems as the CD/DVD is actually 4 discs in 1 case (CD & DVD burning and)
    Playback of CD and DVD). So it is not unusual for parts from 1 or 2 to not work so that others do
    correctly.

    Burning at low speed, or by using the master could help. A CD/DVD cleaner might help.

    Brand of the CD or DVD drive can also be the problem. Low quality (cheap brands) are always problematic.

    CD/DVDs have a tolerance + - and your can read/write on the edge outside these discs
    tolerances. They may be delivered, but it is generally more economical to replace the disk.

    After the foregoing:

    References to Vista also apply to Windows 7.

    Step 1: Please do all the same underneath if you did some before as is often total
    a process that solves the problem.

    Try this - Panel - Device Manager - CD/DVD - double click on the device - driver tab.
    Click on update drivers (this will probably do nothing) - RIGHT click ON the drive - uninstall.
    RESTART this will refresh the default driver stack. Even if the reader does not appear to continue
    below.

    Then, work your way through these - don't forget the drive might be bad, could be a coward
    cable or slight corrosion on the contacts (usually for a laptop) and other issues.

    Another possibility is that the cables are loose. Remove ALL power, then make sure that the cables in both
    ends. Remove and replace, do not just tight. For laptops, you can often clean power and
    contacts data with a pencil eraser.

    Some DVD players do not use the Windows default drivers so check with the manufacturer of system and
    manufacturer of device to see if there is a firmware or drivers for your drive if necessary.

    ===============================

    Step 2: You have disc problems as the CD/DVD is actually 4 discs in 1 case (CD & DVD
    Burn and CD and DVD read). So it is not unusual for 1 or 2 operational so that other parts
    do it right.

    Did you follow the Troubleshooting Guide for the reader who still does not work? There are
    the entries in registry that the troubleshooter does not solve and those who "might" be the cause.

    Check with your Maker system and a device for the two possible firmware updates and the
    correct registry entries for your car.

    Here are the keys that I of course are those in question - for the subkeys of the CD/DVD drive
    as there will be other subkeys in these keys. Do not forget to ask specific keys involved as well as
    the parameters.

    CD/DVD drive someone with the same model.

    Use DevManView to locate the CD/DVD in the registry (be careful and do a prior Restore Point)
    nothing change) - find the DevManView device and then make a right click on it free in RegEdit.

    DevManView - free - an alternative to the standard Windows Device Manager, which displays
    all devices and their properties in flat table, instead of the tree viewer

  • Problem with animation line flicker/aliasing

    Hi I was wondering if anyone had any suggestions on trying to get this smoother animation and a little crisper.

    I know that the quality will be slightly less good in a gif format.

    https://S3.amazonaws.com/uploads.hipchat.com/115279/3089179/b6GFClDGSBHAucu/lines.gif

    Thank you

    Let me give you a few basics. These are things that are not considered by almost everyone that starts working in the video, especially those who come from a print or web design background. Photographers are also victims of a flaw in their knowledge which is understandable because they have never had to deal with things like this before. Here are the facts.

    First Point:
    Video (and everything that comes from digital displays) are always arranged on a grid of pixels. No exception. You can never put a line width of single pixel on this grid of pixels and do appear as a single pixel line, unless it lines up perfectly. Nothing that is not precisely aligned to the pixel grid is interpreted. It is called Anti-aliasing. This means that if your 1-pixel thick line is to halfway between grid display will be the average of the values in this row and you end up with a broad line of two pixels on the screen with each line taking half the value of the color of the original line. In other words if you are not precisely aligned on the grid of your 1-pixel wide black line becomes a 2px wide gray line.

    Second Point:
    Video is composed of images that reading at a particular rate. Your screen also has a refresh rate. Display rate standard in countries that have 60 Hz electricity usually have a refresh rate standard 60 Hz or multiples of a whole number of this rate divider. In countries where electricity is 50 Hz (Europe), the refresh rate is usually 50 Hz. The video frame rate for video in NTSC countries (most of the world) are normalized to 29.97 FPS (there's a reason associated with the problem of broadcasting TV signals in color, but I won't go into that right now). The Standard in PAL countries video frame rate is 25 fps. When you choose a frame rate for your video project which is not the frequency of standard images for your area, you may rate for your video come into conflict with the cadence of your screen. This can cause perfectly smooth motion judder and there is nothing you can do about it, except change the refresh rate of your screen or lift it up with a new high refresh rate capable display or change the frame rate of your video.

    Third Point:

    The average human eye and brain have a property called retinal retention. These effects how we perceive motion. No matter what you do, most people perceive incorrectly flexible movement across their field of vision. Most of the time the brain tries to iron out things and your eyes automatically try and follow this movement. This effect is well understood by the great directors when they block shots and the great directors of photography when they put cameras if your eye is directed to the part of the frame where they want that to get you to understand the history.

    Fourth Point:
    There is a strobe effect that applies to all the movements. For example, if you watch an old movie on TV western, you will sometimes see the wheels of the car rotate backwards. Smart of an airplane propeller video phone can show you that strange Sword-shaped blades turn slowly or even backwards. It's the interaction between pace and movement. The only way to create videos that shows the movement correctly and in the right direction is to match the query of the cadence.

    Fifth Point:
    Work around the fine lines, turning it into a thicker lines is to disable interpolation. You can do in After Effects by selecting quality draft. With quality lit project, you will always have a thick black line of single pixel. This solves a problem, but worse the other. The problem of the stroboscopic effect. To make your single pixel with black line SOUPLESE you must match the query of the line to the frame rate. You move 1 pixel by image or 2 pixels per image or 3 pixels per image or 4. You cannot move to 1.4 or 2.8 pixels per image. It won't wok, it would never work.

    Sixth Point:
    Even if you perfectly fit the pixel grid movement, you can still run on the retinal retention problem and frame rates. Every Director of professional photography with a value of his day rate knows that there are critical speeds of Pan - speeds during which you can not move the camera in a scene and offer a scene that doesn't pan and look terrible. Jerking can be so bad that it gives people headaches and worse. The frequency of images the more cautious, be with the camera. When the video cameras of 24 frames per second were introduced a whole bunch of people came back with horrible images. Shots that run at 29.97 work at 24. Cadence, retention of the retina, strobe effect and your brain combined with no fixed focal point for your eyes to focus on and track combine to fault up to the shooting and of the query.

    The solution:
    When you want to animate a thin line, you're better off at 29.97 frames per second that anything slower. 30 is OK if you go never broadcast or DVD to watch on a TV. You can use an expression to control the movement, so that your line moves exactly an even number of pixels per image. If your design requires that go you faster you must hide the problem with motion blur. If you want to lighten in and clear it of movement then you must hide the problem of aliasing with motion blur. Smooth long moves must be exactly to an even number of pixels per image. You have more options of speed at a higher speed. Even at a higher speed, you will encounter the problem of the sixth Point.

    The evidence:
    Any problem of smoothing by giving you the discount gray lines load the rendering of your lines animated in AE and step as part of an animation at the same time. Baring any cache image and to make the issues I bet that your animation will run without difficulty from one image to the other. It is only when the video plays back at speed that your eyes and your brain will tell you that the movement is uneven.

    Certain standards:
    Go to a cinema and watch the end titles. It takes about 7 or 8 seconds (depending on the height of the frame) for securities to roll from the bottom of the screen upwards. The second seven rule is pretty standard. With 29.97 FPS 1 video per image pixel, 2 pixels per image and 4 pixels per image work well enough for most applications. When you find a speed frame rate works for your video, it's the frame size and it is write it down. Use it again and again.

    This is an expression that works at the speed of the animation and allows blur to apply to your image. You can do the movement meet the markers if you want to start and stop. I have a bunch of preset animations that I use all the time for that style of animation.

    Bottom-up:

    t = time;

    en = t/thisComp.frameDuration;

    x = value [0];

    s = 4; Speed in pixels per image must be an integer

    y = value [1] - (fr * s);

    [x, y]

    Left to right:

    t = time;

    en = t/thisComp.frameDuration;

    y = value [1];

    s = 4; Speed in pixels per image must be an integer

    x = value [1] - (fr * s);

    [x, y]

    If you wish to reverse the direction, you can add a sign less in the final table or apply the term of anchor instead of position. These expressions take the initial starting position of the layer as a starting point. Both are moving to 4 pixels per image. To start and stop the movement, the simplest method is to split the layer, add the expression, let the layer move, then divide the layer again and delete the expression. If you are handy with expressions, you can bind the movement to layer markers, and then just move the markers for start and stop, or even reverse the direction of a single layer.

    If you don't want to mess with all those unbreakable rules then jack up motion blur and uses a higher cadence with thicker lines and hidden defects. There are no other solutions.
