  • Returning a byte array from activex to javascript

    - by vondip
    Hello all, I've built a small activex control using c#. I've got a function that returns an array of bytes. From some reason when I try to consue the returned array in js I receive an undefined value. Why is this happenning? Is there anyway to solve it? Here's a simple demonstration of my code: Activex: [ComVisible(true)] public byte[] Close() { try { MessageBox.Show("called from activex Close"); return Stop(); } catch (Exception e) { //ExceptionHandling.AppException(e); throw e; } } Javascript Call: function CloseActiveX(){ var myRslt = document.OurActiveX.Close(); }

  • Formtastic nested model form fields (Rails 3)

    - by elsurudo
    So here's the scenario: User: has_one :company accepts_nested_attributes_for :company Controller: @user = User.new @user.build_company View: <% semantic_form_for @user, :url => register_path do |form| %> <h2>User Information</h2> <%= form.inputs %> <h2>Company Information</h2> <% form.semantic_fields_for :company do |company| %> <%= company.inputs %> <% end %> <%= form.buttons %> <% end %> After scouring the web, this SEEMS like it should work. However, all I get are the user inputs. The "semantic_fields_for :company" block outputs nothing at all... Am I missing something here, or is this perhaps a Rails 3 bug to do with Formtastic?

  • How to get UIScrollView contentOffset during an animation

    - by user249488
    I am trying to get the contentOffset property of a UIScrollView in the middle of a setContentOffset animation. Note I am not using the animated property of the method, but instead enclosing the setContentOffset operation within a UIView animation block so I can have finer control. When I try to read the value of contentOffset in the middle of the animation, it returns the final value rather than the value at that moment. I know that you can use the presentationLayer to get the current layer, but is there any way you can get the current offset in the middle of an animation?

  • Parse text from a screen grab

    - by Caylem
    Hey guys Not sure the best way to explain this but i'll give it a shot. I'm trying to find a way to parse text/numbers from a screen grab in either C# or Java - whichever provides the easiest way, but preferably java. An example would be as follows. You have a website/document/application with a block of text. You can take a screenshot of the specific area which contains this text. Once the screenshot has been taken you can extract a string from it containing the relevant characters. Any feedback is appreciated. Thanks

  • How to intercept touches events on a MKMapView or UIWebView objects?

    - by Martin
    Hello, I'm not sure what i'm doing wrong but I try to catch touches on a MKMapView object. I subclassed it by creating the following class : #import <UIKit/UIKit.h> #import <MapKit/MapKit.h> @interface MapViewWithTouches : MKMapView { } - (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *) event; @end And the implementation : #import "MapViewWithTouches.h" @implementation MapViewWithTouches - (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *) event { NSLog(@"hello"); //[super touchesBegan:touches withEvent:event]; } @end But it looks like when I use this class, I see nothing on the Console : MapViewWithTouches *mapView = [[MapViewWithTouches alloc] initWithFrame:self.view.frame]; [self.view insertSubview:mapView atIndex:0]; Any idea what I'm doing wrong? Heelp! :) Thanks a lot! Martin

  • JavaScript to detect if the parent frame is of the same origin?

    - by tlrobinson
    I'm looking for a cross-browser way to detect whether the parent frame is the same origin as my frame, preferably without printing warnings on the JavaScript error console. The following seems to work but I'd like to avoid printing errors to the console (at least Safari and Chrome do when accessing location.href on the parent frame. Firefox throws an exception which can be caught): function parentIsSameOrigin() { var result = true; try { result = window.parent.location.href !== undefined; } catch (e) { result = false; } return result; }

  • GAE/JDO: How to check whether a field in a detached object was loaded

    - by tempy
    My DAO detaches and then caches certain objects, and it may retrieve them with different fetch groups. Depending on which fetch group was used to retrieve the object, certain fields of that object may be available, or not. I would like to be able to test whether a given field on that object was loaded or not, but I can't simply check whether the field is null because that results in a "JDODetachedFieldAccessException" which demands that I either not access the field or add detach the field first. I could always catch that exception, but that doesn't smell right. So, does anyone know whether its possible to check if the field was detached?

  • do-while loop in Python?

    - by Eye of Hell
    I need to emulate a do-while loop in a python. But, unfortunately, following straightforward code does not work: l = [ 1, 2, 3 ] i = l.__iter__() s = None while True : if s : print s try : s = i.next() except StopIteration : break print "done" Instead of "1,2,3,done" I have the following output: [stdout:]1 [stdout:]2 [stdout:]3 None['Traceback (most recent call last): ', ' File "test_python.py", line 8, in <module> s = i.next() ', 'StopIteration '] What can I do in order to catch 'stop iteration' excepton and break a while loop properly? Example why such thing may be needed. State machine: s = "" while True : if state is STATE_CODE : if "//" in s : tokens.add( TOKEN_COMMENT, s.split( "//" )[1] ) state = STATE_COMMENT else : tokens.add( TOKEN_CODE, s ) if state is STATE_COMMENT : if "//" in s : tokens.append( TOKEN_COMMENT, s.split( "//" )[1] ) else state = STATE_CODE # re-evaluate same line continue try : s = i.next() except StopIteration : break

  • AjaxSubmit File Upload - Trying to get response $(document).ready() to fire

    - by ncyankee
    I'm using the jquery form plugin (http://malsup.com/jquery/form/) to upload a file via ajax which is processed in the background. The upload is working correctly, and I am using ASP.Net MVC to return a partial view which contains a $(document).ready call to setup a 'timer' to check on the status of the upload file's processing status. When I return the partial view which contains a script block wit ha $(document).ready call, it is never fired, therefore the 'timer' to check for the status of the upload is never started. When I do this via a regular $.post call (without upload) the function fires correctly after the html is loaded into the DOM. Is there anything else I need to do when calling the ajaxSubmit function to get this to fire? Just a sample bit of code: $('form').live('submit', function () { $(this).ajaxSubmit({ success: function (data) { $('#statusDiv').html(data); } }); return false; });

  • Silverlight WCF method calls fails if WCF service is not running initially

    - by Craig
    Quite simply I have a generic Silverlight 3.0 web page that is calling a Ping method on a WCF service. I do not have the WCF service running initially when I navigate to this Silverlight page. As expected I get a communication exception when I press the Silverlight button to call the Ping method, which I catch. Now if I start the WCF service and press the Ping button I still get the communication exception. How come? The other scenario is the WCF is running when I navigate to the SL page and the Ping method call works. I turn off the WCF service, ping method fails. Turn it back on and the ping method succeeds. How come if it's not running initially the ping method fails always? I could include some sample code if you'd like but this is just a real simple Hello World example using basichttpbinding, straight out the book. Thanks, Craig

  • Code folding for LaTeX in Emacs

    - by ShreevatsaR
    Is there an Emacs minor-mode (or piece of elisp code) that lets you selectively hide/show environments while in LaTeX mode? For instance, I would like to move to the beginning of a long \begin{figure} block, hit a keystroke, and have the contents of that figure environment hidden from view. Similarly with \begin{proof} and so on, and ideally even with \subsections. Is this possible? I just tried hs-minor-mode, allout-mode, and outline-minor-mode, but most of them don't recognize LaTeX's environments, e.g. hs-minor-mode fails with "scan error: unbalanced parentheses". I would prefer not to have to enter explicit folding marks like {{{ as in folding-mode. [Ideally it would be great if the folding were persistent, but I see that that question doesn't have an accepted answer yet.]

  • Linq To Sql - DataContext.SubmitChanges() problem

    - by Ahmet Altun
    I have a code like this. DBContext is Datacontext instance. try { TBLORGANISM org = new TBLORGANISM(); org.OrganismDesc = p.Subject; DBContext.TBLORGANISMs.InsertOnSubmit(org); DBContext.SubmitChanges(); } catch (Exception) { } At this point, I want to IGNORE the error and want to be skipped. Not to be retried. But when I try another insert like TBLACTION act = new TBLACTION(); act.ActionDesc = p.ActionName; DBContext.TBLACTIONs.InsertOnSubmit(act); DBContext.SubmitChanges(); SubmitChanges firstly retries previous attempt. How can I tell "skip errors, don't try again"?

  • C# Pragma to suppress break on thrown error

    - by Courtney de Lautour
    First off I run my applications with exceptions thrown on any error (handled or not). Second I am using a TypeConverter to convert from a user input string to the actual object. Third TypeConverter offers no TryConvert method so I'm stuck using exceptions for validation, using this rather ugly bit of code here: try { this._newValue = null; #pragma Magic_SuppressBreakErrorThrown System.Exception this._newValue = this.Converter.ConvertFromString(this._textBox.Text); #pragma Magic_ResumeBreakErrorThrown System.Exception this.HideInvalidNotification(); } catch (Exception exception) { if (exception.InnerException is FormatException) { this.ShowInvalidNotification(this._textBox.Text); } else { throw; } } I'm finding it rather distracting to have VS break execution every-time I type the - of -1, or some other invalid character. I could use something similar to this but not all the types I'm converting to have a TryParse method either. I'm hoping there may be some way to disable breaking for the section of code within the try without changing my exception settings.

  • Unable to get the Current User's Token information

    - by Ram
    Hi, I have been trying to get the currently logged-in user's token information using the following code : [DllImport("wtsapi32.dll", CharSet = CharSet.Auto, SetLastError = true)] static extern bool WTSQueryUserToken(int sessionId, out IntPtr tokenHandle); [DllImport("kernel32.dll", CharSet = CharSet.Auto, SetLastError = true)] static extern uint WTSGetActiveConsoleSessionId(); static void Main(string[] args) { try { int sessionID = (int)WTSGetActiveConsoleSessionId(); if (sessionID != -1) { System.IntPtr currentToken = IntPtr.Zero; bool bRet = WTSQueryUserToken(sessionID, out currentToken); Console.WriteLine("bRet : " + bRet.ToString()); } } catch (Exception) { } } The problem is that, bRet is always false and currentToken is always 0. I am getting the sessionid as 1. Could someone tell me what's going wrong here? I want to use this token information to pass it to the CreateProcessAsUser function from a windows service. Thanks, Ram

  • Technique for ensuring HTML- and URL-encoding

    - by JW
    Has anyone implemented a good template system for ensuring that output is properly HTML-encoded where it makes sense? Maybe even something that recognizes when output should be URL-encoded or JSON-encoded instead? The lazy approach — just encoding all inputs — causes problems when you want to send those inputs to a database, or to a block of JavaScript code. So something a little smarter is needed. The tedious approach — putting the proper encoding function around each piece of data on the template — works, but it's easy for developers to forget to do it. Is there a good approach that makes it easy for developers, and ensures that the right encoding is done? I was listening to one of the SO podcasts, and Joel tossed out an idea about using typed data to enforce a difference between HTML-encoded strings and non-encoded strings. Maybe that could be a starting point. I'm looking more for a strategy than for an implementation in a particular language (although I'd be happy to hear about implementations that already exist and work).

  • Animating a CALayer's mask size change

    - by Alexander Repty
    I have a UIView subclass which uses a CAShapeLayer mask on its CALayer. The mask uses a distinct shape, with three rounded corners and a cut out rectangle in the remaining corner. When I resize my UIView using a standard animation block, the UIView itself and its CALayer resize just fine. The mask, however, is applied instantly, which leads to some drawing issues. I've tried animating the mask's resizing using a CABasicAnimation but didn't have any luck getting the resizing animated. Can I somehow achieve an animated resizing effect on the mask? Do I need to get rid of the mask, or will I have to change something about the way I currently draw the mask (using - (void)drawInContext:(CGContextRef)ctx). Cheers, Alex

  • Is it possible to make customizable WPF styles?

    - by Dheeraj Kumar
    I really like WPF because of its awesome skinning support by changing resourcedictionaries on the fly, but the catch is, the styles must be made by designers in XAML. My client needs a skinnable UI where the end users can make skins themselves. My question is - In Photoshop, you can take any image, and add a color overlay to change all the colors to that hue. Can you do something similar in WPF? I'm just a beginner, and looking at several WPF styles, it seems like all the color values are hard-coded. Here's a sample scenario - user selects two colors from color pickers, and all the controls have a gradient background from Color1 to Color2.

  • How to debug a tcl script which is argument to an executable?

    - by user321047
    I have a application which takes tcl script as argument. I want to debug tcl script when the application processes it. My development environment consists of Dynamic Languages Toolkit from www.eclipse.org/dltk along with Active state remote debugger -dbgp_tcldebug. I am able to debug the individual tcl scripts with this setup. I created a tcl project in eclipse and added 'startup.tcl' and 'argumentScript.tcl' scripts and added following command to the startup script, set ExecutableName "xyz.exe" set returnValue [catch {eval exec $ExecutableName "argumentScript.tcl" } result] My debugger works fine with 'startup.tcl' script. I added the breakpoint in 'argumentScript.tcl' but it is not working. How can I debug the "argumentScript.tcl" script ? Edit: A solution without using eclipse environment is Tcl Dev Kit with remote debugging feature.

  • ExceptionPolicy.HandleException does not install Event Source for Logging in Registry if XBAP run ou

    - by Neo
    I am using the Logging Application Block (of Microsoft Enterprise Library) to log exceptions in the Event Viewer that occur in my WPF XBAP application. If I run the XBAP in the debugger from Visual Studio, an Event Source entry for my application is automatically created in the Registry at: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Application\MyApp This occurs at the point ExceptionPolicy.HandleException() is called. However, if I run the XBAP outside of the IDE directly from the file system or from its published location, the Registry entry isn't added. Therefore, no logging takes place. I can only assume this is a security issue with running XBAP applications and they do not have access to write to the Registry. Is this a setting within my project? Any idea on why this might be happening? Any help much appreciated.

  • Automated testing with Ruby on Rails - best practices

    - by randombits
    Curious, what are you folks doing in as far as automating your unit tests with ruby on rails? Do you create a script that run a rake job in cron and have it mail you results? a pre-commit hook in git? just manual invokation? I understand tests completely, but wondering what are best practices to catch errors before they happen. Let's take for granted that the tests themselves are flawless and work as they should. What's the next step to make sure they reach you with the potentially detrimental results at the right time?

  • Why does a ModalPopupExtender fail when using SSL?

    - by Brooke Jackson
    I have created a modal popup using the ModalPopupExtender in Microsoft's AJAX 1.0 for .NET 2.0. It works great when the page doesn't isn't being accessed through SSL (http://) however the link to close the popup fails to fire if accessing the page through https://. Is the ModalPopupExtender at blame? Is it a "Feature" of SSL to block popups, or is it something else I haven't though of? Here is the code I am using: <asp:Button ID="btnHelp" runat="server" Text="?" CausesValidation="False" /> <asp:Panel ID="pnlHelp" BackColor="white" runat="server"> <asp:LinkButton ID="lnkClosePanel" runat="server" CausesValidation="False" OnClick="lnkCloseHelp_Click">Close</asp:LinkButton> <p>Some Text</p> </asp:Panel> <cc1:ModalPopupExtender ID="popExt" runat="server" TargetControlID="btnHelp" PopupControlID="pnlHelp"></cc1:ModalPopupExtender>

Is there a way to make the main thread block while waiting for user input?
