• .NET Development Hiding sensitive server variables in Application-level trace

  [.Net 2.0] When using Basic Authentication is there a way not to display sensitve info like username/pwd in the trace viewer. Ofcourse, SSL doesnt help here as it just protects the data over the wire but the info is still exposed via the Trace viewer. It would be ideal to be able to hide certain server variables in the application trace output. Is that possible No.. it is not possible to set tracing options for variables.... The most fine-grained you can do it is in the @Page directive.... setting trace settings for each page.... What you can do... is to allow application trace in the web.config file, but disable it in the pages that handle sensitive information like Login page; overriding the web.config ...Show All

• Visual Studio 2008 (Pre-release) XAML Browser Application

  Hi, I have "traditional" .aspx page. This page has small IFRAME Element of size 20x20. I want this IFRAME element to invoke WPF browser application (.xbap url in src attribute). I assume this should not be a problem. Next, my .xbap in IFRAME at runtime generates a "Canvas" of size 400x400. My question is can I make this "Canvas" to cross boundries of IFRAME and render all over base page elements if not, is there any suggestion/workaround for this Thanks in advance. Ganesh Tonde Hi Chango, Thanks this could be the one solution. However, another question (may not be exactly related to this) is can one xbap application in a IFRAME be able to talk to another xb ...Show All

• Visual Studio 2008 (Pre-release) How to get HDC of a control?

  Hi! Can anyone help me with this: How can I get HDC of any control in WPF Is it possible at all If not, then can I at least place a control (which does some stuff using hdc of a child control) which was created earlier in .NET 2.0 onto a WPF form and perform all these great manipulations (scaling, rotating) Thanx for any help! You can get the handle of the Window of a WPF app using WindowInteropHandler , but WPF controls themselves are no longer windows so they don't have handles. You also can not rotate legacy/iterop'd controls. For more on the limitations of interop, read this section of the SDK . HTH, Drew ...Show All

• Visual C# Sound In Form...

  Hi, I was wondering if someone could provide me with some code to simply add a continuous sound playing in the background of a form I have performed a few searches but all examples are really complicated. Isn't there an easier method I guess the easiest solution would be embedding the Windows Media Player control to your application and program against it: 1. From the menu, choose Tools | Choose Menu Items 2. Choose COM Components tab 3. Check Windows Media Player component and click OK - Windows Media Player control gets added to the toolbox 4. Drag the control to your form 5. Set the player's url property to your file location: axWindowsMediaPlayer1.URL = "c:\\mymp3file.mp3" ; An ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Is my video card too old?

  Hi, I searched the forum before I posted :). When I start the SpaceWar game, and run the retro, it puts double ships on the screen. When I start the evolved version, It looks good for about a second and then just goes white. Only some of the graphics are left. I can see the jet engines on the ship, but the background just flashed once when the game starts and then goes away (with the body of the ship itself gone too). It's got double ships too. Is my video card just too old ATI Radeon 7500 I already had to do the graphics.AllowMultiSampling = false ; to get everything working. I'm just thinking if I upgrade all will go well. Thanks .

• Visual C# Exchange data between two applications

  I'm looking for a way to exchange data between two applications running on the same system, one in Delphi and the other in C# ( in the future the one in C# will become dll assembly in SQL Server 2005) What I rejected: - extern files, - shared memory (it needs kernel32.dll to be imported ) - MS Message Queue (default Windows installation has no msmq) I thought about using pipes or sockets, but sockets need separate listening-thread...

  My question is with regards to custom assembly resolution. I know that a common mechanism for participating in assembly resolution is to subscribe to the AppDomain.AssemblyResolve event.

• Visual Studio VS .Net 2005 package failed to load with domain roaming user profile

  When starting up VS 2005 says package XML editor, and package explorer and designer failed to load. Therefore any "visual" functionalities can not be used: can't display a form, no toolbox gadgets, no visual debugging. And even can't create any new project. The problem has troubled me for a week. Tried everything (reinstallation/cleaning registry/reinstalling .net) but didn't work. So I had the machine reformatted and reinstalled everything starting from windows -- And the problem is still here! Then I realized this has something with my user profile, which is saved on a domain server and reloaded to local machine every time I log on.

  I have a XAML in whose controltemplate, there is a button for which there is CommandBinding as follows: Command="{Binding Path=Some_Command}" where SomeCommand is a class that inherits from ICommand and an object of which is exposed via a Public Property of another Class. For a button in the XAML that is not in a Control Template, the binding works fine and the command executes as well - however the same does not work for th Control Template case.
