Yes, I agree with you. I developed a small program to check the behavior of WM_CLOSE. And It does its job.

Anyway:

If you want to check how many thread is used by your program just open the task manager then click on menu View->Set Column and then choose thread check box, You will get the thread count

I just came to that conclusion, that I did not handle my WndProc Correctly. So I started to remodel it with a better understanding. I must admit that I should check for open threads still running during one of the events.

I do need some help in organization and clarity here.

WM_CLOSE
Gives me a chance to do something before WM_DESTROY is called

WM_DESTROY
That's it, shutting down, I must do something, or it just shuts down

WM_QUIT
I'm suppose to PostQuitMessage(0), 0 means close, 1 means abort?

case IDM_FILE_EXIT:
PostMessage(hWnd, WM_CLOSE, 0, 0);
break;

case WM_CLOSE:
  {
    // Catch the Event and do something before shutting down
    msgboxID = MessageBoxEx(g_hWndMainFrame,
    L"Are you sure you wish to quite Internet Commerce Engine 5",
    L"Question",
    MB_OKCANCEL | MB_DEFBUTTON1 | MB_ICONINFORMATION,
    LANG_NEUTRAL
    );
  }

  switch ( msgboxID )
  {
      case IDOK:
      PostQuitMessage(0);
      DestroyWindow(hWnd);
      break;

      case IDCANCEL:
      PostQuitMessage(1);
      break;
  }
  break;

  case WM_DESTROY:
      // Perform Cleanup Tasks

      break;

  case WM_QUIT:

      PostQuitMessage(0);
      break;

The parameter is an exit code that you want to return from your program. The numbers do not mean anything unless you, as the programmer, define a meaning for them.

When the thread retrieves the WM_QUIT message from its message queue, it should exit its message loop and return control to the system.

I need to fix my child window first. I think I have the main window fixed. I have the same loop in the parent window and child window, so the child window is still running the loop when I try to shutdown the main window.

Now I'm starting to think that I have to call DestroyWindow for each control as well.

Main Window

case WM_CLOSE:
        {
            // Catch the Event and do something before shutting down
            msgboxID = MessageBoxEx(g_hWndMainFrame,
            L"Are you sure you wish to quit Internet Commerce Engine 5",

            MB_OKCANCEL | MB_DEFBUTTON1 | MB_ICONINFORMATION,
            LANG_NEUTRAL
            );

            switch ( msgboxID )
            {
                case IDOK:
                    Sleep(1000);
                    PostQuitMessage(0);

                    //return 0;
                    break;

                case IDCANCEL:
                    return 1;

        }
        break;

    case WM_DESTROY:
        DestroyWindow(hWnd);
        break;

    case WM_QUIT:

        break;

Child Window

case WM_CLOSE:			
{
	HMENU	hMenu;
	HMENU	hManagementMenu;
		
	hMenu = GetMenu( gUserAccount_Index_GAC );
	EnableMenuItem(hMenu, 1, MF_BYPOSITION | MF_ENABLED);            
	hManagementMenu = GetSubMenu(hMenu, 1);
	EnableMenuItem(hManagementMenu, IDM_MANAGEMENT, MF_BYCOMMAND | MF_ENABLED);
	DrawMenuBar( gUserAccount_Index_GAC );				
}

return 0;
break;
		
case WM_DESTROY:
{
	if ( hUserAccount_Index )

I want the message loop in the mdi child window for the tab function

If I take this out of the mdi child main, the main parent window and process shuts down fine.

But I want to have access to the tab key, so I'm not quite sure how to proceed. This is the thread that is running from the mdi child window.

MSG msg;
    int bReturn;
    while ((bReturn = GetMessage(&msg, NULL, 0, 0)) !=0) {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }
    ReleaseDC(NULL, hdc);
    return (int) msg.wParam;

That's funny, but pretty much what it is.

I narrowed it down to the message loop in my child window. guess I need to test for the WM_DESTROY message manually to kill the loop.

There's nothing wrong with that line, it's a C-style structure definition, which is also valid in C++. You probably have a problem somewhere before that header is loaded and it's just causing the compiler to think there's a problem with that definition. Look for missing ';' characters in the file where you included this header.

look at the lines in your cpp code before the include of richole.h, there might be a syntax error there that is manifesting itself in the h file. Don't forget, "include" is the equivalent of "paste the file here" so you should think of the cpp file as one continuous piece.

It is telling you there's a syntax error in the included RichOle.h header file, at line 18.

Pardon the silly question: "Did you include windows.h, before it?"

Sometime some Visual Studio compiler error is really confusing.

As far I can understand may be there is no error in neither your source code or your RichOle.h Source code. Probably its missing some special header file that defines lots of macros. Make sure your windows.h is defined before RichOle.h

Stefan_Lang12-Jan-12 1:23

I, too, consider this the most likely cause.

It's sad how in so many years of compiler history, MS still fails to create their headers in a way that does not require a specific order of inclusion. It wouldn't be so bad, if that wouldn't trigger totally unrelated error messages, but apparently they don't get that either.

A practical solution is to use the VS Project Wizard to create a new Windows application (MDI, SDI, or dialog-based, depending on your needs), and switch on precompiled headers, then copy the resulting stdafx.h into your own project. It should contain the inclusion statements for windows.h and pretty much everything else you need, and in the correct order. (this is only to get the full list of include statements, and in the right order - you can also just copy the include lines from stdafx.h to the relevant cpp files in your project instead if you don't use PCH)

You're trying to display an animation on a dialog? You know, most of the things on that dialog you linked can be done with MFC without the use of an animation (using controls), but you can also use animations to make them more personalized.
