• How to bind Checked event for radio button in WPF?

  - by nullDev

  I am using the following markup in WPF: <StackPanel.Triggers> <EventTrigger RoutedEvent="RadioButton.Checked" SourceName="xmlRadioButton"> <EventTrigger.Actions> <BeginStoryboard Storyboard="{StaticResource ShowXmlPanel}"/> </EventTrigger.Actions> </EventTrigger> <EventTrigger RoutedEvent="RadioButton.Checked" SourceName="adiRadioButton"> <EventTrigger.Actions> <BeginStoryboard Storyboard="{StaticResource ShowAdiPanel}"/> </EventTrigger.Actions> </EventTrigger> </StackPanel.Triggers> Though this works fine when I run the code, I get the following error in the designer window of VS 2008: Value 'RadioButton.Checked' cannot be assigned to property 'RoutedEvent'. Invalid event name. Any idea why, and how can I fix this?

• Process.Start concatenating cmd line from previous invocation

  - by Ralph

  Hi, I am using a Process.Start in .Net 2.0 to start a child win32 app. Process.start ( "SomeProcess.exe", "<Cmd line>" ); The process runs fine but and the user then closes this window. However if I then run the same process again in the same session, the cmd line recieved by the called process is now a concatentation of the previous call. I.e SomeProcess.exe recieves the cmd line " SomeProcess.exe ". Has anyone else seen this behaviour before? Any help much appreciated. Ralph.

• RegisterClientScriptBlock code not executing.

  - by ProfK

  I'm using the following code in an attempt to show a dialog with a list of errors on the client: if (rollout.ImportErrors.Count > 0) { ClientScript.RegisterClientScriptBlock(GetType(), "showErrors", "showErrors();", true); } The error count is non-zero and the following script block is emitted, but the script isn't executing. <script type="text/javascript"> //<![CDATA[ $("#error-report").dialog("open")//]]> </script> If I call the function directly from a Firebug console window, the dialog shows properly, so I know the dialog and my code are working. What am I doing wrong? BTW, this code is in a content page, using a content placeholder that 'injects' code into the element of the rendered page.

• Adding an attribute to a class by using properties editor

  - by Fred Yang

  Visual studio allows you to design component visually. For example, you are designing a windows form. You change its property in the properties editor. The IDE will generate the code in a partial class in xx.designer.cs file. We can customize this behavior by changing the UITypeEditor for the properties. The question now is , Can we extend this code generation behavior? for example, we change a setting in property window, and then the IDE will add an .net Attribute to the class? Thanks

• Difference between focus and focus-in(out)-event signals

  - by spajak

  Hello What's the difference between "focus" and "focus-in(out)-event" signals in GTK+? Which one is emitted firs? How are they related to keyboard(TAB) & mouse clicks. Do they depend on each other? I'm asking this because I want to keep track of currently focused widget within toplevel window and I don't want to test HAS_FOCUS flag of every widget when I need it. The widgets I'm interested of are deep inside other containers, boxes etc. What would be the best way in this situation for keeping & updating focused widget pointer?

• Delphi Prism getting Unknown Identifier "DllImport" error

  - by Robo

  I'm trying to call Window's SendMessage method in Delphi Prism, I've declared the class as follow: type MyUtils = public static class private [DllImport("user32.dll", CharSet := CharSet.Auto)] method SendMessage(hWnd:IntPtr; Msg:UInt32; wParam:IntPtr; lParam:IntPtr):IntPtr; external; protected public end; When I tried to compile, I get the error Unknown identifier "DllImport" I used this as an example, http://stackoverflow.com/questions/2708520/how-to-call-function-createprocess-in-delphi-prism and the syntax looks the same. Is there a setting I need to enable, or do I have a syntax error?

• MKMapView within UITableView

  - by john-london

  I have a MKMapView within a UITableviewCell and I want to be able to disable scrolling of the table view when the user starts to drag within the map view. My plan had been to override the MKMapView touchesBegan/Moved etc methods and if they were called to then disable scrolling in the parent view. Scrolling in the parent view would be enabled again only when the touches in the MKMapView ended or were cancelled. My problem is that the touchesBegan/Moved methods inside MKMapView are not called - the problem is also discussed here: stackoverflow discussion. My table view is within a tab control, so I don't think I can extend UIWindow the way they describe, as there are several views that could be within the window, depending on which tab is active. How can I access the MKMapView touch events please?

• WPF win app and browser app

  - by pdiddy

  I'm hearing this alot, that you can develop an app in WPF and run it as a desktop app or in a browser. Is this really true? I've install visual studio 2010 and I see 2 project templates : WPF Windows Application and WPF Browser Application (XBAP). Currently reading a book on WPF, it talks about Page-Base app, which can be use for navigation. To creatre an app to run on your browser you have to use the WPF Browser Application. So if I start with WPF Windows Application template can I run it in a browser ? I am assuming not since most of my class will be Window and not Page ....

• Google Maps & jQuery InfoWindow Replacement

  - by Denis Hoctor

  Hi all, So I'm rewriting my first google maps app and I'm looking at how I create info windows on click of a marker and it seems very inefficent to be adding a listener for each. Previously I've used GInfoWindow and EBubble (http://econym.org.uk/gmap/ebubble.htm). I was thinking that I could use jQuery to show a div with dynamic data if I had a hook for each marker to show the window and relevant marker info (pulled from JSON). I can see each marker has a unique id (e.g. mtgt_unnamed_2822) but I'm not sure how to predicte this. Has anyone tried this before or know how to go about it? Thanks Denis

• Redirect output to file

  - by Algorist

  Hi, I have a shell script which is currently running and was running from past 8 hours. It will complete only by tomorrow evening. At the end of the program, it will print 2 million words to standard output. I am running the program on the screen. I forgot to redirect the output to a file. I know I won't be able to copy the data from the window. Is there a way to output the command to a file. I don't want to restart the program. Any thoughts?? Thank you. Bala

• Adding rows to UItableview and passing data between Viewcontrollers

  - by Jonathan

  I have a list of websites in a plist, when the app loads this populates a tableview (which is inside a navigation controller) But I have added an add button to the navigation bar and then created another View Controller to deal with inputting of the new website (Like Title and URL). It is very similar to how the contacts app looks. There is a table view and when you tap add, the add UI slides up. I have got all this working great so far. My Problem is what happens when the user taps Done. I can add the website to the plist (each website is a dictionary in the plist with 2 keys, atm) But then how do I tell the tableView to update? The table view has not been removed from the main window, just the add view has been added on top of the "screen". Another way of asking is, when you tap Save on Add a Contact screen: (not my image) How does the new contact's data (Xyz's data) get shown on the tableview?

• What response Adobe Acrobat/Reader gets back after submitting form to a PHP script

  - by Laszlo

  Hi, PDF experts help needed, I am posting a form from PDF to a PHP script with Adobe Acrobat. I would like to set my PDF to display appropiate messages based upon some returned values. So I am looking for returned values... if there is any returned values after posting the form, how can I access them? Maybe, there is an option to set this in Adobe? Another thing: When the PDF form gets submitted and let's say I echo back a 'thank you' message from my form-handler PHP script, a new PDF gets created and opened displaying my message... is there a way to open that new message in the same window and close the form instead? Thanks, Laz

• Silverlight MVVM conversion from WPF

  - by IrishJoker

  I was reading this article - http://msdn.microsoft.com/en-us/magazine/dd419663.aspx And I came across this piece of code in the WPF Demo application that came with the article. This template applies a CustomerView to an instance of the CustomerViewModel class shown in the main window. <DataTemplate DataType="{x:Type vm:CustomerViewModel}"> <vw:CustomerView /> </DataTemplate> I substituted the angle brackets for square brackets - not sure how to post them. The code is in the MainWindowResourses.xaml and the code starts on line 19. Anyone know how I can do this in Silverlight ?? We don't have the DataType and I need to be able to tell the app that this View is associated with this ViewModel - so I can create a tab control with different view like the demo app. Cheers, EC

• UIAlertView Dismiss Not Really Dismissed

  - by Jim Bonner

  Below is the code I'm using to do a retry on an FBConnect session. When the [self loginToFaceBook] fires FBConnect adds a subview to 'window' which is still the UIAlert view, so when the UIAlert really dismisses it takes the FBConnect view with it. Any idea as to the best way to wait for the UIAlert view to be gone. -(void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex { if([self respondsToSelector:@selector(alertContinue)]) { [self alertContinue]; } } -(void)alertContinue { SocialLiteAppDelegate *appDelegate = (SocialLiteAppDelegate *)[[UIApplication sharedApplication] delegate]; [appDelegate.fbSession logout]; [self loginToFaceBook]; }

• Why is LOGON_USER Server Variable is blank on New Windows / New Tab?

  - by Alex Papadimoulis

  We are noticing some very strange behavior on an installation of a .NET2-based webapp on Server 2008. Our app uses "old school" Integrated Windows Authentication and simply reads the LOGIN_USER server variable from the request collection. There's a good reason for this, but that's somewhat irrelevant to the question, since the underlying WindowsAuthentication code from ASP.NET does the same thing. Anyway... When you enter the URL in the browser, it loads up just fine and displays the username (from LOGIN_USER) no problem. When you click on a link within the web app, it loads the page just fine and authenticates without any problems. When you "hard refresh" (Ctrl-F5) it also works just fine. However, when you click "open in a new window" or "open in a new tab", the LOGON_USER variable is blank Any ideas? Am I missing some IIS7 setting somewhere? Tested clients are Windows 7 with IE8 or Windows XP with IE6.

• Eclipse: Subclipse "Edit Conflicts"

  - by Wilco

  I have found that when using Subclipse to edit conflicts, all my syntax color settings are preserved except for the background color, which is reset to the standard white. Using my particular color scheme makes it almost impossible to read any of the text when stuck with a white background. Is there anywhere I can change this default background color? There doesn't seem to be any way to do this from the preferences window, but perhaps there is a config file somewhere I could edit? Any help would be very much appreciated (my eyes will thank you too)!

• Python class design - Splitting up big classes into multiple ones to group functionality

  - by Ivo Wetzel

  OK I've got 2 really big classes 1k lines each that I currently have split up into multiple ones. They then get recombined using multiple inheritance. Now I'm wondering, if there is any cleaner/better more pythonic way of doing this. Completely factoring them out would result in endless amounts of self.otherself.do_something calls, which I don't think is the way it should be done. To make things clear here's what it currently looks like: from gui_events import GUIEvents # event handlers from gui_helpers import GUIHelpers # helper methods that don't directly modify the GUI # GUI.py class GUI(gtk.Window, GUIEvents, GUIHelpers): # general stuff here stuff here One problem that is result of this is Pylint complaining giving me trillions of "init not called" / "undefined attribute" / "attribute accessed before definition" warnings.

• GAE, Python 2.5, Python 2.6 Side-by-side on windows

  - by Software Enthusiastic

  Hi On my development system, I have python 2.6, python 1.1 and GAE. I have three projects running on python 2.6 and django 1.1. And 1 project using GAE, Python 2.6 and django 1.1. I have heard that, my set-up for running GAE using python 2.6 may create some head scratching problems while deploying it on the production server, because GAE supports only python 2.5. And using 2.6 is not recommended. Can I develop GAE application using python 2.6? If not what should be the solution, I am using Window vista as my development system.

• tptp/profiling of web-application within eclipse - no data collectors available

  - by AJ

  Hi, I have a problem with tptp/profiling within eclipse. Because at first I had some very strange problems, I downloaded the “TPTP all-in-one package” (tptp.runtime.allInOne.win32.win32.x86-TPTP-4.6.2.zip) and added the stuff I need (Jboss-Tools, etc.) I am using Windows XP SP3, Java 6u20, Eclipse 3.5.2.(, jboss-4.2.3.GA-jdk6) In "Profile Configurations"/Tab "Monitor" I got “IWAT0435E An error occurred when connecting to the host” and in the “Profile on Server” Window in the tab Monitor I got only “pre-JRE 1.5“ as choice. After disabling an enabling the IAC in “Preferences”/”Agent Controller” that IWAT...-problem was gone but now I don't get anything in the “Profile on Server”/”Monitor” tab, but it says “[Monitor] The launch requires at least one data collector to be selected.” any ideas?

• Sprite movement

  - by Lemmons

  Hi everyone. I'm ripping my hair out over this one. For some odd reason I cannot find out / think of how to move a sprite in SFML and or SDL. The tutorials I've looked at for both libraries state nothing about this; so I assume that it's more of a C++ thing than a library thing. So I was wondering; how do you move a sprite? (When I say move, I mean have the sprite "glide" across the window at a set speed)

• Skype Raw API (NOT COM API) send message problem

  - by Mike Trader

  In converting this CONSOLE example to a full windows dialog implementation I have run into a very "simple problem". SendMessage() (line 283) is returning zero, GetLastError reveals 0x578 - Invalid window handle. http://read.pudn.com/downloads51/sourcecode/windows/multimedia/175678/msgapitest.cpp__.htm (https://developer.skype.com/Download/Sample...example_win.zip) C++ 2005 Studio express edition instructions http://forum.skype.com/index.php?showtopic=54549 The previous call using HWND_BROADCAST works and Skype replies as expected, so I know Skype is installed and working properly. The handle I use is the wParam value from the Skype Reply message, as in the code. This is non zero, but I am not sure if there is a way to test it other than with SendMessage. The compiled app from this C++ code example (see zip download) does actually work so I am stumped. I do encode the message with UTF8, and I create an instance of the COPYDATASTRUCT in my app, populate it then call SendMessage() with the COPYDATASTRUCT pointer in lparam. Skype does not respond nor does it obey. Am I missing something obvious here?

• Javascript, AJAX, Extend PHP Session Timeout, Bank Timeout

  - by Guhan Iyer

  Greetings, I have the following JS code: var reloadTimer = function (options) { var seconds = options.seconds || 0, logoutURL = options.logoutURL, message = options.message; this.start = function () { setTimeout(function (){ if ( confirm(message) ) { // RESET TIMER HERE $.get("renewSession.php"); } else { window.location.href = logoutURL; } }, seconds * 1000); } return this; }; And I would like to have the timer reset where I have the comment for RESET TIMER HERE. I have tried a few different things to no avail. Also the code calling this block is the following: var timer = reloadTimer({ seconds:20, logoutURL: 'logout.php', message:'Do you want to stay logged in?'}); timer.start(); The code may look familiar as I found it on SO :-) Thanks!
