• Visual C++ window pointer for a new window

  Hi, I have created a new window using the following method AfxGetMainWnd()->PostMessage(WM_COMMAND, ID_FILE_NEW); How can I get a pointer to this new window What is the difference between a window handle and a window pointer Pritha If the ID_FILE_NEW command succeeded, a new view object will be created and activated. In order to obtain it, I think you can try the GetMainWnd()->GetActiveView() function. (See the documentation of CActiveView about how to do this differently in case of MDI applications). Note that the new window is created after fully processing of ID_FILE_NEW command. Therefore you probably should try SendMessage instead of PostMessage . Otherwise GetActiveView will be called ...Show All

• Windows Forms Execute custom action without installing the assembly.

  Hello all... I'm using Visual Studio 2005 to create an MSI for a legacy VB6 app. The MSI mostly just registers a bunch of COM DLLs. However, the MSI also needs to install a new code group to the machine. I have written a .NET DLL that will install the code group without a problem. I added this DLL to the Setup Project and used it as a 'Custom Action'. Everything works fine. The only problem is that the DLL is installed to the machine. I don't want this to happen because the DLL's only purpose is to create the code group. It does nothing else. I tried setting the 'Exclude' property to True for the DLL, but that doesn't work, either. I even tried setting the 'ExcludeFilter' property to '*.dll' for the assembly. Nothing works. It seems tha ...Show All
