• GREP - Positive look behind - find the text beyond the space

  I have a GREP in a paragraph with a positive Outlook style behind. This research finds the characters up to a space and apply a style, but applies style beyond a space.

  What should I include in my GREP search to find text following a space? TIA

  Right. He finds only upper case and lower case letters, while the game ends on what is not one of these. Do you want to match the end of the paragraph? You can use (?.)<>

  for two words use (?)<>

  for a game for one or two words (two if there are two, otherwise only one), try (?.)<=\#)[\l\u]+(\s[\l\u]+)? (not="">

• GREP: Negative look-behind using

  Hi guys,.

  It has been a long week of InDesigning and I have a little problem that my brain no longer has the capacity for.

  What I need to do, it is find not preceded by a full stop paragraph breaks and then change them to a space.

  I am wanting a GREP expression, obviously. I'll be back as a negative look-behind coup.

  See you soon,.

• Save my Clip Positions of film with PHP and MySQL

  Hello
  
  I created a video (FLV) Player, who just plays my videos. Everything works fine and I would like to add a new button to save the position according to which the film played up to. So I can come back later and have the opportunity to play the film to the point that the last time he was arrested. Therefore, I need to save my Clip Positions of film with PHP and MySQL.
  
  So far, I created a button that saves the position of the my video clip "ns.time' in a variable. I'm currently just display this variable, but I need to export to my file PHP where it gets sorted to be sent to mySQL database. Could you tell m e how can be down or where I can find more material (tutorial) to achieve this.
  
  I tried to export using 'getURL(url,window,method)' that points to my PHP file. But for some reason any when he sends some information to my php and not only the Position of Movie Clip. I realized from the address line that attempts to send millions of movie flow information, etc..
  
  I realized that Flash tries to send information of my Listbox and trees which are the list of film clips I have. I don't know why he's trying to send this information! Is anyway I can stop the Flash to send information to my PHP file and send only the value of my a Variable?
  
  Here's how I send the value of the Variable entry in the PHP file...
  
  getURL (" http://www.myDomainName.com/aishopper/test2/matrix.php","", "GET" ");
  
  Thank you so much and have a great day.

• Specimen of Positioning System blower with Galil controller

  Hi all

  So to say the least I am super frustrated with my LabVIEW program right now. This project requires that I use only of LabVIEW and GalilTools software, so I can't use C or C++ or any other person. I wrote about what the code I need would look like in C/C++, but I'm having a lot of trouble to create a LabVIEW program that does the same thing. I have attached the VI I've written so far. I have also attached my operating scheme to help understanding outside of my intentions. Also attached an OpsManual dictates the structure of my interface planned and everything that it should do.
  I know there is much to look at, but I'd be very happy to help. I've looked everywhere on the examples and the forums and youtube tutorials and I'm just really having trouble, and this particular stage takes too long.

  The basis for this project is that it is a positioning system managed by 2 stepper motors with angular limits specified. All engine configurations is processed by the GalilTools software. The logic must be managed in LabVIEW. This requires the adoption of values in both directions between LabVIEW and the controller.

  I'm doing some specific things are currently doing me wrong:
  -the output messages back as program at each stage movements (LabVIEW not spend several channels to the same Terminal without other things in between, I have not yet found a way)

  -Connect the wires of the reference and error programmatically (I understand this is how the program passes the values and it also affects the operation of the program, I'm not sure how to connect a mine and have my program still works as expected, also runs the question of having several wires to a terminal that LabVIEW won't)

  -emergency stop button (I need this cable in so that it can stop the program at any time, similar to the demolition)

  There are many other issues that will arise as I move forward, but those are the current, I worked on that. I'm fighting with which structures should be used. It's just not quite as intuitive for me like C/C++ has been.

  Thanks in advance for any help provided.

  A few thoughts for you to consider.

  The Galil aspect

  • You do not need to download your Galil program every time, connect using Galiltools or GalilSuite and download and then use the BP command to burn the program in memory.
  • Put anything in #AUTO which must be executed each time the controller is running.
  • Operation most have a complementary _cmd operand that can be queried. IE: BGA will start movement on axis 1, MG _BGA returns 1 if still in motion, or 0 if the request is completed.

  For the side of LabVIEW

  • Replace the case separated by a single event structure structures. Given any how do you now without delay in means of the loop that you run each of these cases as soon as your program can.
  • Get rid of all calls to Galil outside the structure of the event. If you wish to check the status or the movement of code, put it in the case of timeout or consider another loop that runs independently of your main loop.
  • Keep in mind the operation of the son, means anyone to load data only if two sons are in a structure or function they both must contain data before the structure or even runs. Other you can make threads where you need.

• Web page looks good with tranparent and photographic background in mode boxes live view, but not in browsers

  If someone has the time to help, I would be very grateful.   I am new to dreamweaver and I try to make a transparent Web page with columns and text box using styles.  It looks perfect in 'live view', but when I look in any browser all the formatting has disappeared.  It looks like the background with the text at the top of installed on wrapped throughout the entire page.   I was not able to understand what is wrong in the days of research.  Anyone know the answer?

  < div class = "box739" >

  < h3 > what do NBCS? < / h3 >

  < p > since 2004 the Bay of Narragansett Coyote study (NBCS) has developed strategies of coexistence and based management sciences for our most recent top-level predator.  Coyotes, originally a species of Prairie, have successfully colonized all parts of the continental and coastal us over the past 100 years. They reached the islands of Narragansett Bay in the middle of the 1990s. Since then the coyotes have become more and more abundant and problematic in some communities of the island. < /p >

  < p > in our history of cohabitation with the coyotes people constantly tried to eliminate them by hunting, trapping and poisoning. Lethal removal worked for individual problem animals but did not work as a strategy of population control. Why? Coyotes have physiological and behavioural abilities intrinsic to control their own numbers. If the coyotes are removed they increase reproduction and numbers to rebound quickly. The trigger of critical population regulation is competition for food. As long as the coyotes are well fed (with a few coyotes competing for food) their populations will grow. < /p >

  < p > we know also that the opposite effect occurs if the coyotes if the coyotes are stressed by competition for food. If there are too many coyotes competing for the available food coyotes will drop the sustainable level of these resources. < /p >

  < p > understanding of this relationship, the NBCS scientists decided to study the use of the resources of coyotes on two islands of Narragansett Bay, Rhode Island. We used GPS to find out location necklaces where coyotes are spending their time. We have made the assumption that if we could identify food resources important coyote - control - coyotes defray their own numbers. NBCS called & quot; management passive coyote. & quot; < /p >

  < p > since 2005 when we are caught in the trap and to collar our first coyotes on the island that we found continuously as the most important food resources of our study are provided people. This means that they are in our command this means that we can control the coyotes. If we remove anthropogenic resources (human grants) coyote numbers will drop to the sustainable level of natural resources. When the coyotes are fed only natural prey number of coyotes (mice, woodchucks, rabbits, geese and deer) will be lower and they will provide useful pest services. < /p >

  < p > according to our science NBCS generated a set of < has href = ' coyotes/best' practices for Coexistence with Coyotes - 8 Nov 2010.pdf management target = "_new" > best management practices for Coexistence with Coyotes < /a > - essentially a Toolbox for safe and sustainable community management, coyote. We work with the cities in our study area to adopt the CBMPs and be the first community in the nation to successfully and sustainably manage coyotes. We believe also in other cities and towns might be able to use our results as a template if they have problems of coyote. We have barely begun to implement the CBMPs on our islands. We soon hope to have all our implementation of the CBMPs cities - only, then we will see the full impact they make on the coyote numbers and behavior problems.

  From the looks of your screenshot, I'd say it's a path problem.  Are you sure that you downloaded the CSS document when you loaded the page and that the path is correct?  It appears in your second screenshot that there is no style applied so your stylesheet is not included for a wrong path or because it is simply not there.

• The photos in photo looks blurry, with large pixels. Recorded images were of high resolution, why what is happening?

  I used the migration assistant to transfer all the data from my old macbook pro to my new iMac, now the images in the Photos seem to be blurred, with large pixels. Recorded images were of high resolution, why what is happening? Is it possible to fix it. In the old macbook pro, the image looks ok.

  Migration assistant has a really bad experience with iPhoto and Photos

  If you still your old MB of available space, connect it to your new Mac (network, mode target firewire or use an external to the Mac OS extended (journaled) format hard drive and drag the iPhoto library folder images on the new Mac and heck the iPhoto library to icon in the Dock to migrate Photos)

  I hope this will work better

• positioning of objects with applescript

  Hi all, I'm a noob to applescript and I started to learn its basics to automate difficult tasks from my daily work.

  I wrote a very simple code and it actually works, but I need to refine it.

  Here it is:

  Tell application "Adobe InDesign CC 2014"

  tell the active document

  say all master spread

  tell each page to make the rectangle with properties {race weight: 0, absolute horizontal scale: 1, absolute vertical scale: 1, fill color: 'Paper', the transparency settings: {mixture parameters: {opacity 0.1}}}

  tell the end

  tell the end

  tell the end

  This script automatically place my rectangle somewhere in the upper left corner - why? -of each page; I tried on another mac, but it works as well, because the rectangle is displayed outside the page.

  So, is there a way to tell my rectangle to, for example, align the top margin of each page, in the Middle? In this way he shouldn't have problems more...

  We hope to find a way, thank you all.

  Alessandro

  Position you a rectangle via geometric limits:

  Tell application "Adobe InDesign CS6"

  tell the active document

  -get the display preferences and define units of inches and the origin of the page

  Properties of the viewprefs value display preferences

  Set the properties of the display preferences {horizontal measurement units: inch, vertical measurement units: inches, origin origin: the rule page}

  -the limits of the rectangle in y1, x 1, y2, size 2 x

  -y1 and x 1 are the x, the coordinates of the upper left corner against parameters of the rule

  -y2 and x 2 are the lower right

  - so it's a square of 3 "

  mybounds value {1.0, 2.0, 4.0, 5.0}

  say all master spread

  tell each page to make the rectangle with properties {geometric limits: mybounds, the race weight: 0, fill color: "Black"}

  tell the end

  -reset the leaders

  set the properties of the display preferences for viewprefs

  tell the end

  tell the end

• After Effects behind with just 14 seconds of clips

  Initially, I shot a lot of video with a Canon Vixia HF G30 in AVCHD. When I realized that Mac cannot read this format correctly, I used handbrake to convert them to MP4 using the H.264 codec. I am all videos stored on an external hard drive of 1 TB and dragging into a folder on my desktop when I need them. I imported 2 clips in my composition in After Effects totally 14 seconds of video. I can't do anything in AE. I try to slide the clip in position and moves it to a very small amount and then crashes. I have a MacBook Pro with 8 GB of RAM, 6 GB of which dedicate themselves to After Effects.

  I have worked with After Effects several times but never had that bad of a problem with such a tiny amount of sequences. I think that perhaps it would be too big of a file of suggestions on how to convert it into a smaller file without loss of quality would be very useful. Thank you very much.

  ksoqueso wrote:

  I am the preview by pressing the space bar

  Ah. Found your problem! You misunderstand how to use After Effects! AE is not a real-time editing application. It is a composer based on pixels. As any composer based on pixels, you must return an overview. And sometimes it can take very long to make depending on your effects. You should not press SPACEBAR to preview. After effects help. Preview

  Because you didn't know how to do something as simple as the preview, I'll suggest to take a big step back and start here: starting After Effects

  There are probably a TON of useful stuff you need to know that you have missed.

  I had staples of 14 seconds that took a lot more than 2 hours to make. You just have to know to set up your scene correctly and how to work with the software. All your problems come from not understanding how the After Effects (or how to work with After Effects).

• Symbols indicating no position of retouching with goTo

  I'm working on a simple game of spot-the-difference, a pair of photos with hotspots, users click on each picture to take differences.

  

  It is a Flash CS5 project with a film class, a class for the circles.  It worked fine with one 'level', but I am trying to add extra 'levels' by adding a new keyframe in the timeline panel for each additional level. So, I create a new keyframe and add a new pair of photos and reposition the symbols that are circles in order to match with the new photos:

  

  In my film class, when the level one is finished, I have the ACE: this.gotoAndStop(this.currentFrame+1);

  The images change the images of frame 2, but circles are in the same position they were in frame 1.  Editing posts are ignored.

  What I'm missing here?  This can be corrected?  I would position rather visually of the circles of each layer in on the scene for simplicity.

  This is probably an old Flash anomaly at work... When you have the same objects in adjacent keyframes objects as part of the latter will assume the properties of those in the previous image.  Try putting an empty keyframe between each level column, so that objects do not fall into this trap.

• Dreamweaver 8.0.2 &amp; quot; Position &amp; quot; Problem with WebDav

  Dreamweaver 8.0.2 'Put' problem with WebDav
  
  In Dreamweaver:
  I am able to see all the local files, and I can see all the files in the remote control. So here's the kicker... "Dreamweaver is only allowing me"Read"access" depending on the distance. When I try to 'Put' files on the server, I get an error indicating the failure of the option could... "Access denied" I use the same exact references in DW8 with WebDav.
  
  In Windows:
  In Windows (my network places), I use 'Web folders' Windows XP to display a window of the Explorer of my files from remote servers. Read, write, modify, delete works very well since Windows "web folders". I'm sure that 'web folders' are an example of a WebDAV client. When I access the file (remote) server through Internet Explorer 7 and Internet Folers (WebDav client) I can write, read, edit, delete.
  
  What we tried:
  -We give full access. Still does not work.
  -We have updated Dreamweaver to DW8.0.2 and it still won't work.

  Is it a question of rights of Windwos, Microsoft IIS problem or dreameaver?
  Help... Help... HELP - thanks.
  

  We found the answer... We must remove the extension in IIS. In IIS, you must go to the IIS application configuration > Home Directory Configuration... > App Mappings > remove used Extensions. By removing the ASP, ASPX and APP SHTML extension mappings, we were able to upload files to the site.

  Web site 2: establishing a second IIS website devoted management WebDAV requests. Read point # 3 *.

  This is the size of the text of the article.
  Disable the server from ASP script, the script ColdFusion server or another server in script, that you may be using. To do this click on the "Configuration" button... "in the screen shot above and the deletion of the appropriate DLL. This will prevent IIS to send the script server to the application for processing server-side. Someone a ColdFusion page would like to see ColdFusion pre-treated for editing code, not the resultant post-processed code HTML.

  Everything now works fine... Tech Support from Adobe phone helped us to solve this one. Thank you.

• Firefox is lagging behind with no mouse activity

  When I open all websites, they start to load then stops, this also happens with youtube videos. However, if I move the mouse or click the icon firefox showing all open windows simply by watching a video, it is not a problem. Can I fix? I had the most recent Firefox and same version uninstalled.

  Hi winsyao, several other affected users have reported that it was a problem caused by malicious software on their pc.
  Please run a full scan of your system with the free version of malwarebytes and adwcleaner (these two security tools are free).
