• Smart Device Development BackgroundWorker class

  Is BackgroundWorker available in compact framework I need to implement a downloading app for my PPC and i find BackgroundWorker as the easist and the best solution but MSDN says it is available only in .NET framework. I think there is nothing OS specific in the class and should be available in compact framework. Also there are a lot of open source implementations of this class available for CF but i would like to use only MS version. When will it be ported to CF Why do you want to use "only MS version" You can get a free implementation of it here: http://www.danielmoth.com/Blog/2004/12/backgroundwo ...Show All

• Software Development for Windows Vista simple performance question

  Which of the following systems has more performance (and why, of course....):     System A: with 100 workflowRuntimes each of them runing 10 workflows. or     System B: with 10 workflowRuntimes each of them runing 100 workflows. (assuming that workflows use statePersistance service and are consuming similar amounts of resources (procesor, DB, etc) ) Thanks in advance, Ariel Schapiro . Ariel, Your scenario sounds interesting, but it doesn't sound like you really have high-throughput going through your system.  Instead of trying to coordinate work between multiple dispa ...Show All

• Visual Studio VS IDE crashes when debugging in managed or mixed mode

  I have a c++ project that uses a .NET 1.1 assembly as a com object. It is loaded with CoCreateInstance. If I debug in native mode it looks like everything works okey, in managed mode the application crashes with no errors or anything, and in mixed mode Visual Studio crashes. Something that looks somewhat suspisous to me is that it looks like .NET framework 2.0 assemblies and debug symbols are loaded. For example: 'MyApp.exe': Loaded 'C:\WINDOWS\Microsoft.NET\Framework\v2.0.50215\fusion.dll', No symbols loaded. 'MyApp.exe': Loaded 'C:\WINDOWS\Microsoft.NET\Framework\v2.0.50215\msvcr80.dll', PDB format is obsolete. 'MyApp.exe': Loaded 'C:\WI ...Show All

• SQL Server Changing Connection string in multiple packages.

  Scenario: 130 dtsx packages using 4 matching connections. 3 of those connections are stored in an SSIS Configuration table in an Operational database. The last connection is in a shared data source and points to the Operational database so the packages can grab the others. Problem: It's time for deployment and all of those connections must change to production servers. The 3 are no issue, just change the ConfiguredValue in the SSIS Configuration table on the production box to point to the other production servers. However, the fourth one...

• Visual Basic REALLY Weird "Threading Problem" - Hard to explain

  Hello all. I''m currently in the [process of making an audio player application that will read out MP3 tag information using the Speech library (the MS Text-To-Speech thing - like the one in control panel.) Well, I had built the application using the VB .NET 2005  Betas, and it worked fine throughout - no problems. I downloaded the final version of both the framework and VB IDE itself. I compiled & ran, and got some strange error that I had never gotten before. Below is the result of what the IDE could tell me.

• Visual C++ lnk1112

  In VS2005, I added a MFC DLL project. The default platform is win32 and this project does not have input lib. A very simple boiler plate project with code from Microsoft. Then I converted the project to x64 by setting the platform type to x64. I can see that the target machine type from the Linker option got changed to x64. Then I built the project from VS2005, I got the following error: \ x64\Debug\mfc2.obj : fatal error LNK1112: module machine type 'X86' conflicts with target machine type 'x64' Note that there is no input library and therefore there cannot be a mix of object modules. The only object module is the mfc2. ...Show All
