问题 I was working out a problem with a ddl trying to get a message box to popup when the item changed.

问题 I run VS2010 Pro on a Windows XP machine. I have downloaded and installed PEX & Moles. That all went fine. When I open a C#-project and position the cursor on a class method and rightclick, I see no 'run pex' or 'pex' choice, as should be the case according to (install) docu. As far as I could see I have done all by the book, but no joy. It seems I forget something somewhere but what?

问题 I did a custom button control in WPF and I am trying to implement it in WinForms (c#). Now, the control is working and it compiles well, but I can't seem to access the elementhost - the control was not shown in the toolbox, and afterwards I saw it's frozen, i.e. I can't add it to the form. Since the project build process went without errors or warnings, I don't know what is causing the problem. Any help would be appreciated, thanks. EDIT: Here's the code of the xaml file: <Button x:Class=

问题 I have 32 bit .net application solution project. It uses many third party dlls (32 bit). This app runs on both 32 bit and 64 bit (as a 32 bit process, compatibility mode) platform. It uses 32 bit DLLs even if it is running on 64 bit platform. I need to rebuild this application in order to let it use/load 32 bit Dll on 32 bit OS and use/load 64 bit DLLs on 64 bit OS. As existing 32 bit app runs on 64 bit systems in compatibility mode but I want it to be run as a dedicated 64 bit app on 64 bit
