• .NET Development Locale of ThreadPool's Thread

  Is there any way to modify CurrentCulture/CurrentUICulture of ThreadPool's threads OR to set the default values of these properties for every thread created within a process hmmm... that means I have to set the culture in whatever function I pass to QueueUserWorkItem . I think there should be an option to set the default culture for all threads within a process. Framework might want to change (talking about TP) it for its own but can restore it before calling the user code. ...Show All

• Visual C++ Disable Found New Hardware Wizard

  Is there a way to prevent (with some API calls) the Found New Hardware Wizard from starting when a new device appears. I need to write a service that will install the drivers for a device when it appears without any user assistance. The actual device is not known beforehand, so the preinstalling of the required drivers before the device is plugged is not an option.   zelenoto wrote: Is there a way to prevent (with some API calls) the Found New Hardware Wizard from starting when a new device appears.  Yes it should be possible using WMI.  You can either write your own script if you understand WMI well or search the net for WMI scripts to do this.  BTW this question ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. TorqueXNA

  I had a look at the XNA version of the Torque 2d engine and noticed that it converted 4mb worth of png files into over 60mb of xna files; Is this a Torque issue or xna as its a massive increase and would make releasing any games online a virtual impossibility. Thanks Shawn, but I'm not sure if that answered the question. For example, I have a splash screen that goes from 5.21kb in PNG format to 1.10MB (1126.4kb) in XNB format - over 216 times bigger. Is there something I have to change in the properties for that file to keep it from getting inflated ...Show All

• SQL Server Scheduled SQL Server Agent SSIS Package Job Problem

  HELP! I have been banging my head against a brick wall on this one all this morning AAAAAAGGGHHH! 1. I have an SSIS package that runs a simple SQL script and then updates a few tables by downloading some XML of the web. It runs fine when I kick it off manually under SSMS. 2. I created a SQL Server Agent job to run it every day. This always fails. The error information in the log is useless ("Executed as user: domain\user. The package execution failed. The step failed." - I had already figured that out!). It fails almost straight away, and when I enable logging for the SSIS package, no info is ever logged (text file, windows event log, whatever). 3. Out of desperation I have changed Agent to run under the same domain user ...Show All

• .NET Development Com Object in .Net on an x64 machine.

  Ok So I have written MANY Com objects in .net that are used in vbscript and elsewhere with no real hitch on x86 platforms. I have run into a perplexing problem when writing a trivial COM object and trying to invoke it from wscript or cscript on an x64 box. Here is what I have done: Write a tiny com object in VS2005.

• Game Technologies: DirectX, XNA, XACT, etc. Color Banding

  I am getting color banding issues when viewing my project on my Xbox 360. The textures look perfect when the app is ran on windows, using the same XNA source just in a different project. But when I display the textures on an Xbox 360, I get serious color banding. These issues are most pronounced when my Xbox is set to output at 720p or higher resolutions, but the color banding is still there even if the Xbox is set to 480p. The following code is what I am using to setup my 'prefered' values for my graphics device. If you got any idea what could be causing this, I would appreciate the input. graphics.IsFullScreen = true ; graphics.PreferredBackBufferFormat = graphics.GraphicsDevice.DisplayMode.Format; graphics.PreferredBackBufferH ...Show All

• Software Development for Windows Vista Visual Studio 2005 Macros and 5744

  Macros in Visual Studio seems to have stopped working in Vista RC2. When attaching to vsmsvr.exe exceptions are thrown when you try to run a macro from devenv.exe. From debugging the disassebly I think it is a access denied message. I also saw a string "Bad IL format" if that helps. Anyone have an idea how to solve this issue without waiting for RTM or going back to RC1 I don't get any exceptions or other errors. But it does not work either. Running a macro does nothing. Debugging macros is the same... nothing happens. Probably this is something to be fixed in the RTM SP1. ...Show All
