  • Error message when running a Sinatra application on Windows Vista.

    - by Adam Siddhi
    I was following a video tutorial by Adam Keys about how to make a URL shortener app in Sinatra. The code that is giving me problems is located here http://pastie.org/958644 So when I ran it I got this error: shortener.rb:12: syntax error, unexpected $undefined, expecting $end @@ home I typed it exactly as Adam said but this keeps happening. What could the issue be? By the way, I am running ruby 1.9.1p243 (2009-07-16 revision 24175) [i386-mingw32] on Windows Vista. Thanks, Adam

  • How to detect in a Flex app if a camera is already in use by another application?

    - by Alex Fisherr
    I am making an application that plays the video stream from the user's local system (both Windows and Mac). I use the Camera.getCamera() method and in turn Camera.names to get a list of camera attached with the system. Unfortunately, if the camera is already in use by another application, say a desktop application on user's system, the browser is crashed. Is there any way that I can detect if a specific camera from the list of available camera is already in use by any other application?

    - by Krantz
    Hello, I need to build out a feature that will let the content authors know if a particular asset (e.g. an Image or a video under site assets library) is being referenced by any content(Pages) in the sharepoint site. Is there any built-in feature that can assist in that? If not, do you have any suggestions on how should I go about it? Thanks, Krantz

  • embed dll in html <object>

    - by Raynos
    I've come across some old code <object id="foo" classid="/location/bar.dll#ProjectName.ClassName" viewastext></object> It doesn't currently work and used to work in older versions of IE. I've never come across embedding a dll in a web page like this. It appears to be a windows .NET application written in C#. This is used on our intranet. And ClassName is of type System.Windows.Forms.UserControl It also seems I can call the C# methods of the UserControl directly through javascript. Does anyone have any documentation on how this works and whether its possible to hack it into firefox. Rewriting the windows control as a web application would be a nightmare. [Edit] It appears to be some kind of activeX / COM thing where in IE you could just port a windows application directly into a html file. It's supposed to be able to run locally if you set up various correctly. If anyone has an idea of what needs to be set up for this to work, that would be nice.

  • Why AVCaptureSession output a wrong orientation?

    - by Peter
    Hey guys, So, I followed Apple's instructions to capture video session using AVCaptureSession: http://developer.apple.com/iphone/library/qa/qa2010/qa1702.html. One problem I'm facing is that even though the orientation of the camera / iphone device is vertical (and the AVCaptureVideoPreviewLayer shows a vertical camera stream), the output image seems to be in the landscape mode. I checked the width and height of imageBuffer inside imageFromSampleBuffer: of the sample code, and I got 640px and 480px respectively. Does anyone know why this's the case? Thanks!

  • unable to capture picture using camera in j2me polish?

    - by SIVAKUMAR.J
    I'm, developing a mobile app in j2me.Now im converting it into j2me polish. In my app I capture a picture using camera in mobile phone. It works fine in j2me. But it does not work fine in j2me polish. I cannot resolve it. The code snippet given below public class VideoCanvas extends Canvas { // private VideoMIDlet midlet; // Form frm Form frm=null; public VideoCanvas(VideoControl videoControl) { int width = getWidth(); int height = getHeight(); // this.midlet = midlet; //videoControl.initDisplayMode(VideoControl.USE_DIRECT_VIDEO, this); //Canvas canvas = StyleSheet.currentScreen; //canvas = MasterCanvas.instance; videoControl.initDisplayMode( VideoControl.USE_DIRECT_VIDEO,this); try { videoControl.setDisplayLocation(2, 2); videoControl.setDisplaySize(width - 4, height - 4); } catch (MediaException me) {} videoControl.setVisible(true); } public VideoCanvas(VideoControl videoControl,Form ff) { frm=ff; int width = getWidth(); int height = getHeight(); // this.midlet = midlet; Ticker ticker=new Ticker("B4 video controll init"); frm.setTicker(ticker); //Canvas canvas = StyleSheet.currentScreen; videoControl.initDisplayMode(VideoControl.USE_DIRECT_VIDEO,this); ticker=new Ticker("after video controll init"); frm.setTicker(ticker); try { videoControl.setDisplayLocation(2, 2); videoControl.setDisplaySize(width - 4, height - 4); } catch (MediaException me) {} videoControl.setVisible(true); ticker=new Ticker("Device not supported"); frm.setTicker(ticker); } public void paint(Graphics g) { int width = getWidth(); int height = getHeight(); g.setColor(0x00ff00); g.drawRect(0, 0, width - 1, height - 1); g.drawRect(1, 1, width - 3, height - 3); } } In normal j2me the above code works correctly. But in j2me polish videoControl.initDisplayMode(VideoControl.USE_DIRECT_VIDEO,this) here this refers to VideoCanvas (which extends from javax.microedition.lcdui.Canvas). But it throws an "IllegalArgumentException - container should be canvas" like that. How to solve the issue?

  • How To Share Information Between Django and Javascript?

    - by Randy
    So I am pretty new to both Django and Javascript (I am using JQuery) and I am wondering if I am doing a hack or if there are more slick ways to send client-side displayed database ids to the django server-side. Here is my process: I have a dataTable (http://datatables.net) that I am displaying rows of data by using the bProcessing option to use AJAX to retrieve records from the database. The URL in my urls.py is something like: url(r'^assets/activitylog/(?P<cid>.*)$', views.getActivityTable_ajax, name="activitylog_table"), and my dataTable ajax-relavant code is something like: "sAjaxSource": "/assets/activitylog/" + getIDFromHTML(), where the javascript function getIDFromHTML() grabs <cid> that is used by the Django view is simply: function getIDFromHTML(){ // Simply return the text in the #release_id div element from the HTML return $("#release_id").html(); }; This is the part that seems "hacky" to me. I am inserting into my template code the database id that I am using in the datatables URL (with display:none in the css) just so I can pass it back to the view. Most of this is necessitated because one cannot use django template tags in the javascript code unless the code is embedded into the HTML itself, which I am not (and will not) do. The only other thing that I have found is to change the URL to get rid of the parameter passed in to: url(r'^assets/activitylog', views.getActivityTable_ajax, name="activitylog_table"), and change the view code to: def getActivityTable_ajax(request): """Returns the activity for a given pid from HTTP GET ajax reqest""" pid = int(urlparse.urlparse(request.META['HTTP_REFERER']).path.split('/')[-1]) # rest of view code here... since the id that I need is on the end of this referer url. This way I don't have to monkey around with embedding the hidden database id into the HTML and passing it back to via ajax the the table population view code. Is it okay to use HTTP_REFERER in the request object in this manner? Am I going about this in the totally wrong way? Thanks in advance!

  • UIVideoAtPathIsCompatibleWithSavedPhotosAlbum generates error implicit declaration of function, why?

    - by just_another_coder
    In my project I am trying to save video to the iPhone after being taken by the camera. When I call the method: UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(path) It reports the error: Implicit declaration of function 'UIVideoAtPathIsCompatibleWithSavedPhotosAlbum' I've imported MobileCoreServices/UTCoreTypes.h I was previously using this same code for saving camera pictures, and it worked fine. In another class, in the same project, I am able to reference the UIKit method: UIImagePNGRepresentation() without any problems So why does it give me this error?

  • Is there any tutorial on connecting .NET 4 Pipeline with Pipeline from some C\C++ programm?

    - by Ole Jak
    Is there any tutorial on connecting .NET 4 Pipeline with Pipeline from some C\C++ programm? For example how to get data from VLC Pipeline output ... I mean VLC docs say that there command line args can eat name of pipe like YUV video output --yuv-file=<string> How to give such name to pipe created in your .Net programm so to be able to give it to other programms or resive from other programms?

  • Querying a 3rd party website's database from my website

    - by Mong134
    The Goal: To retrieve information from a 3rd party database based off of a user's query on my ASP.NET website The Details: I need to be able to search 3rd-party websites for information relating to pharmaceutical drugs. Basically, here's what I've been tasked with: a user starts entering the name of a drug they're using in their experiments, and while they're typing a 3rd party website (e.g., here or here) is queried and suggestions are made based based off of what they've typed. Once they've made a selection, certain properties (molecular weight, chemical structure, etc) are retrieved from the 3rd party database and stored in our database. PharmaGKB.org's search bar is pretty much what I need to implement, but I need to access a 3rd party db. The site that I'm working on is ASP.NET/C#. The Problem: I don't really know where to start with this. There's a downloadable Perl example at the bottom of the page here, but it didn't really help me all that much. I'm at a loss as to how to implement this, or even find information about how to do it. The AJAX toolkit was suggested, but I'm not sure if that will solve the issue. JavaScript is also being considered, but again, I'm not sure if that will be sufficient, either. Perl Example Connection As a mentioned, here is a snippet from the Perl example given on the Pharmgkb.org site: my $call = SOAP::Lite -> readable (1) -> uri('SearchService') -> proxy('http://www.pharmgkb.org/services/SearchService') -> search ($ARGV[0]); However, I'm not sure how to implement this is C#/ASP.NET/JavaScript. There's a question on Stack Overflow about embedding Perl in C#, but it require a C wrapper as well, and I don't think that three languages is necessary or wise to solve this issue.

  • What are the arguments against the inclusion of server side scripting in JavaScript code blocks?

    - by James Wiseman
    I've been arguing for some time against embedding server-side tags in JavaScript code, but was put on the spot today by a developer who seemed unconvinced The code in question was a legacy ASP application, although this is largely unimportant as it could equally apply to ASP.NET or PHP (for example). The example in question revolved around the use of a constant that they had defined in ServerSide code. 'VB Const MY_CONST: MY_CONST = 1 If sMyVbVar = MY_CONST Then 'Do Something End If //JavaScript if (sMyJsVar === "<%= MY_CONST%>"){ //DoSomething } My standard arguments against this are: Script injection: The server-side tag could include code that can break the JavaScript code Unit testing. Harder to isolate units of code for testing Code Separation : We should keep web page technologies apart as much as possible. The reason for doing this was so that the developer did not have to define the constant in two places. They reasoned that as it was a value that they controlled, that it wasn't subject to script injection. This reduced my justification for (1) to "We're trying to keep the standards simple, and defining exception cases would confuse people" The unit testing and code separation arguments did not hold water either, as the page itself was a horrible amalgam of HTML, JavaScript, ASP.NET, CSS, XML....you name it, it was there. No code that was every going to be included in this page could possibly be unit tested. So I found myself feeling like a bit of a pedant insisting that the code was changed, given the circumstances. Are there any further arguments that might support my reasoning, or am I, in fact being a bit pedantic in this insistence?
