The string number fails when letter after the number?

kind of confused I hope someone can answer this question. I have a function to verify that a string is a number as such.




isNaN(parseInt(num));



return !isNaN(parseInt(num));}


Public function isNumeric(num:String):Boolean             { 


so, if a shipment in the 'aa' value, it returns false. Great! However, if I send '1a', it returns true. However, it is not a number? can anyone offer suggestions. I ti I test more away this by looking at what value the function it's after I have send value "1a" and he thinks that the value is '1', so I guess my only other option to stop this would be to move the channel to a table and to loop through the entire string looking for non-numeric values? what I do?

Miguel

Maybe try to use instead of parseInt number?

public void isNumeric(num:String):Boolean {}

return! isNaN (Number (num));

}

  • Doc XML to a string fails when the string length is greater than 512 bytes.

    I have been using the following code to write an XML string.  If the resulting string is lower to ~ 512 bytes, the string will be created, if > ~ 512 bytes, the routine does not create the string.  Assuming that the doc contains an XML document:

    Doc CVIXMLDocument = 0;
    HDoc MSXMLObj_IXMLDOMDocument = 0;

    ...

    cvistatus = CVIXMLSaveDocument (doc, 0, "Test1.xml");
    status = CVIXMLGetDocumentActiveXHandle(doc, &hDoc);)

    hRlt = MSXML_IXMLDOMDocumentGetxml (hDoc, & errInfo & strXml);

    The SaveDocument routine still works, the XML file contains the XML, regardless of their size.

    The Getxml routine creates only the XML string in strXml when the length of the string is lower to ~ 512 bytes.

    Does anyone have an idea of the problem?

    Because the string is very long, the ICB debugger cannot display. That's why I was wondering if you were trying to print using put or printf. Because the return value is 0 and the ERRORINFO is also stating the success, I would recheck the chain by printing it to the console or a file.

  • Project Manager fails to cut after the new method to "consolidate and transcode.

    Greetings,

    I use first to create trailers and other equipment for a game studio. For the record, I use dxtory ( http://exkode.com/dxtory-features-en.html ), with the first/AE allows you to change the images and SOUL for rendering. A project may consist of several hundreds of GB's worth of the source footage. When made with a given project, historically I used method 'trim' first since the project manager to store copies ready images - as it is intended. This can turn a project with 400 GB of source down to a cup which is only 80 GB or more. This has worked well in the past, but because of the recent change to the new feature to "Consolidate and transcode", this operation will fail when the current creation.

    I created a full repro this for anyone who would like to try.

    The repro project: https://dl.dropboxusercontent.com/u/263501/misc/PremiereRepro/Copied_transcode_repro.7z

    I'm using Project Manager, select the following options:

    https://DL.dropboxusercontent.com/u/263501/Misc/PremiereRepro/pp_transcode_2.PNG

    This should lead to a MB avi ~9.9, which is 15 images of the larger video, the panoramic nature views slightly to the right.

    Instead, I get the following message after the end:

    https://DL.dropboxusercontent.com/u/263501/Misc/PremiereRepro/pp_transcode_1.PNG

    Looking at the directory for this new project "successful", the size of the file is the same as the source of the layer and without cropping footage actually occurred.

    The journal of the events, said the same thing:

    https://DL.dropboxusercontent.com/u/263501/Misc/PremiereRepro/pp_transcode_3.PNG

    This method worked 100% reliable before the new feature to "consolidate and transcode. It seems to be quite broken in the current one, at least for my purposes. I forgot something, or is this a bug? I am currently having to install an earlier version of first trying to work around this problem, but this obviously isn't the solution.

    You receive this warning as the selected Format (DNxHD MXF OP1a) does not support your combination of the size of the image, frame the combination of rate and on the ground. For example, DNxHD will support sizes 1280 x 720 or 1920 x 1080, while your source file is 1280 x 800.

    Try using a combination of Format/Preset that will support your settings of the source file. For example: Source of game (Mac) ProRes or CineForm Match (Mac and Windows).

    I hope this helps.

  • IDCS5/MAC - Style GREP in capital letters of a letter after a hyphen between the words

    G ' Day here.

    I'm trying to create a GREP style for uppercase letter after a hyphen between the words, specifically with a word beginning with a capital and after a dash do not for example Lorem-ipsum = Lorem -Ipsum

    The full story, it's that there is an indesign batch file used over and over again that family names that are in a large database of data - merge. Data arrives in capital letters and our mail barcoding software allows us to title case some fields, but the behavior of title case has the following results:

    * = Mcleod McLeod

    * = Agostino Agostino

    * Smith-Bunting = Smith-Bunting

    I was able to solve the = problem with the following GREP style Mcleod McLeod:

    (?<=Mc)\l
    

    and then apply a character style that is nothing more than all caps.

    Similarly, I was able to solve the problem = D'Agostino of Agostino:

    (?<=\u')\l
    

    and once more apply style all uppercase to the letter assigned. This also solves the problem of O 'leary to o' Leary.

    However, when I try these GREPs to enter style Bunting-Smith questions:

    (?<=\u\l+?-)\l     or   (?<=\u\l{2,}-)\l
    

    the search does not work, nor will it work with regular replacement of find/change GREP... and yet the expression \u\l+?-\l will find the block I'm after.

    I could use the search

    (?<=\l-)\l
    

    and is that Smit untingh-b= Smith-Bunting... but there is also co-ontervenir = co-Ontervenir (find two words with a hyphen but begins with a lowercase letter).

    That's fine if the paragraph style is applied to the line in the address block containing the name of the client, but if the name is mentioned in a text block, then that block of text must have the paragraph with the GREP style applied style and dashes between words in that para is in the same way as the name.

    Yes, it is possible to go into excel and use the PROPER (cell affected) = and fix fields Smith-Bunting, but I am trying to create a solution that only works in InDesign so that other operators in the office (who are not familiar with excel) can simply open the file of commands and dump in the database to txt generated by the mail bar coding software.

    There are other names that-case of barcoding mail title fault upward, i.e.

    * = Macleod MacLeod

    * van der Graaf = Van Der Graaf

    * van Diemen = Van Diemen

    but a GREP make MacLeod of Macleod can clog Mack, Mackie or Macy become MacK, MacKie or MacY.

    I also know that a GREP for the van der or van will not work as the style will force letters only to be all uppercase, not uppercase to lower...

    In the end...

    does anyone know how to style GREP (not a find/change GREP) a fix for Xxxxx-xxxxx = Xxxxx-Xxxxx?

    Colly

    Colecandoo.

    I agree with Haakenlid on his reviews of Dirty-workaround - in my opinion, the data should be entered in the way which it oguht, not altered by some magical GREP styles - but then again, I can also sympathize with your POV re: a fire-and-forget solution even your stupidest operator can not miss.

    Oh the rigors of life.

    If you are totally, absolutely certain you want to GREP for that, use this:

    b define a character to capitals on the chain style

    \b\u\l+\-\l

    -This will change as if by magic "the Honourable lieutenant Sir John Forsythe Blunt-object" in "BLUNT object".

    (b) then replace (!) the first half with another style of character that removes the attribute of capitals (!):

    \b\u\l+-(?=\l)

    Notice how this expression is exactly the same as the one above, except for the latest code - the next tiny need also be captured, but now, by using an advanced search for its formatting will be not affected.

    This command removes the substitution all uppercase the first halve, change 'BLUNT-object' 'Blunt-object '.

    Many side effects, I'm sure. Maybe it 's safer to teach your operators to run a single script.

  • Writing PNG file failed when build exe, but operate normally on the development platform

    See photo below, it is used to call WinAPI for screenshot and then save it in PNG file.

The pop-up dialog error 'chain of illegal path, OS', but it is clear that the path is correct. Note: run the same PC with Win XP.

    Hello Lisa,.

    It's more to do with the word processor on Windows. You don't say what word processing software you use. If you use WordPad which comes free with Windows, it is impossible to do what you want to do. However, if you are using Microsoft Office Word (that you can buy) then the CAP is set by default.

    Hello

    Make sure that you do not install hardware 3rd party via windows update drivers

    they are normally not up to date and can cause computer problems

    change the way you receive updates and check what you install ad if you don't not right-clicking on UAC prompt you to hide it:

    http://www.bleepingcomputer.com/tutorials/tutorial140.html

    Download updates but let me choose whether to install them - if you select this option, Windows will download the updates on your computer, but not install them automatically. If you want to install updates, then you must install them manually. You should only select this option if you have a reason to not install updates automatically. Only advanced users should use this option.

    Check for updates but let me choose whether to download and install them - if you select this option, you'll be alerted when there are new updates available for download and install. You can then choose to download and install the updates that you want. This option should really be reserved for people who know exactly which updates they need, or those who have little access to the Internet.

    and if you're still stuck in a loop non-Boot read these methods on how to try to fix it:

  • Bluetooth control fails to initialize after mating

    Hi all

    I have a problem similar to a previous question (here). I use Windows 7 Home Premium 64 - bit on an HP HDX 16 with Broadcom integrated wireless. I have associated my pioneer What AS-BT200 attached to a VSX-921 k. This device has been paired before (it can use 3 codes pairings - 0000, 1234, 8888 - and I've matched initially by using the 0000 pairing code) but now it wouldn't connect. I have problem different havea pair my headset Rocketfish BT and found that it would not connect automatically, so I have to open my Bluetooth devices, right click on the device and click the control. In Control Panel, click on connect and let it open to keep the connection (really, why's do not connect an option from the context menu...?) Sorry, Rant off)). I thought that this could be the problem with this camera as well, but when I try to open the control I get the error message:

    "This operation could not initialize. Try again after turning off the Bluetooth and then back on. If the operation fails to initialize, try again after restarting this computer. »

    Long story short (er), I tried to restart the receiver and computer several times, I tried to remove the device and matched on all peel them three codes (he made pair, installs drivers and shows well, but does not connect), I checked, I last Broadcom Dirvers, I checked that the BT from my computer connects to other devices (D100 Creative - no problem (, Rocketfish headphone with the hoops above) and also checked that the computer was not connected to another device. I checked that the AS-BT200 connect to other devices (connect to my I-Touch).

    No idea why this device breaks down or how I can get it to connect?

    Hello

    Here is a solution I found which may be useful for you.

    If you go into the settings of your Bluetooth adapter, you should see a tab for Audio.

    No tab for Audio - tabs are Options, some COM Ports, hardware, sharing and PIM

    In this tab, you should see "Stereo Bluetooth Audio, headphone" listed. Highlight and select "connect".

    No parameters don't like that in the previously listed tabs.

    If this is not the case, the next step is to open the control panel and go to his. So for the first tab called reading. Who listed there, you should see the Bluetooth device you connected previously. Stress and make the default playback device.

    Playback of bluetooth device is grayed out without an active connection, and while it is gray, it does not define it as default playback device.

    All that said... today for no reason discernible he leaves not open the Bluetooth control window, but when I pressed the connect button that failed.  I reset everything and am now at the original error.  So I don't know why he has allowed an opening time of the control panel for the BT device or why the connection failed when he opened the window.  I will pursue other options and check with the technical support of Pioneer as well.  I'll post here if I get any where, but because I'm leaving on a 4-month business trip soon I can just put it out of this matter until the holiday when I get back.  Thanks to all who helped me this weird error.

  • Noron 360 sometimes cannot be started on Windows 8 when starting after a stop!

    Hello

    I have a desktop computer running Norton 360 first Edition version (current) 20.4.0.44 with the latest definitions for viruses on Microsoft Windows 8 Professional with Media Center. Norton 360 , sometimes fails to start on Windows 8 , when starting after a stop.

    Since I first installed the new version of 'version-less' 2013 Norton 360 on Windows 8, it sometimes does not start at startup after a stop and did not bother to mobilize support for that matter because I thought that Symantec or Microsoft could be aware of the problem and that an update or a patch will be available soon. Norton 360 prompted me to apply a new patch today, and after applying the patch, I have realized that the amended version of the version 20.3.0.36 to version 20.4.0.44. Moreover, I also noticed that the aforesaid problem with Norton 360 persists, and if my memory is good, Norton 360 sometimes also does not start after the resumption of hibernation. I used to put the computer to sleep and I never have this issue when hybrid sleep. For Norton 360 upward and run again, I usually just give the computer a reboot.

    I believe that the function "quick start" in power options Windows 8 are originally Norton 360 sometimes fails start. I haven't noticed this problem on computers that are running Windows XP or Windows 7. If Symantec or Microsoft may arrive at a solution to this problem without having to turn off the quick start of Windows 8feature, I would be very grateful!

    Kind regards

    Hi Doug,.

    Kindly let me know what Norton product, you try to use, and if download you the latest version of the internet, or you install a version earlier than either downloaded or a disc? Please also post the specifications of your computer and operating system incl. architecture and the edition you are running.

    Regarding your question: are you affected by the same problem that I did? Only Norton only lack of start from time to time, or Norton fails it run continuously?

    If Norton sometimes does not start on a computer that is running Microsoft Windows 8:

    Disable the "quick start" function in Windows 8 by going to the bar of charms > settings > Panel > material and audio > Power Options > Choose this as the power button , then click on change settings that are currently unavailable, uncheck the enable fast start (recommended) and click on save changes. Restart your computer to test if Norton starts up. If Norton still does not start, uninstall Norton completely, restart your computer, download and run the latest version of Norton removal tool from Symantec website, computer restartyour once more. Then download the latest version of your Norton product either downloading the trial, or you connecting to your Norton account if you have a valid subscription and clicking on the button to download next to your subscription. Install the latest version of your Norton product and manually run the direct updated until all the updates and hotfixes without restarting have been installed and no updates are available before stopping or restarting your computer!

    If Norton does not at all on a computer running Microsoft Windows 8:

    Uninstall Norton completely, restart your computer, download and run the latest version of the Norton removal tool from Symantec website, computer restartyour once more. Then download the latest version of your Norton product either downloading the trial, or you connecting to your Norton account if you have a valid subscription and clicking on the button to download next to your subscription. Install the latest version of your Norton product and manually run the direct updated until all the updates and hotfixes without restarting have been installed and no updates are available before stopping or restarting your computer!

    Please feel free to ask me more questions about, or contact me if you have problems, uninstalling, reinstalling, downloading, install the latest version of your product, Norton , or if you are having trouble updating your Norton product! I would also gladly provide via TeamViewer remote assistance, if you need my help!

    Please mark this answer as useful and/or answered if you found my answer helpful and/or my reply has answered your question!
