Okay, here's an example:

TProcessDialog* pr = new TProcessDialog(this, IDD_PROCESS, 0, 999);

newpr->Create();
newpr->Show(SW_SHOW);

// Disable main window
GetApplication()->GetMainWindow()->EnableWindow(FALSE);

for (int i = 0; i < 1000; i++) {
  char  buf[255];
  if ( !newpr->IsWindow() ) {
    MessageBeep(0xFFFF);
    break;      // Break if window doesn't exist
  }
  wsprintf(buf, "%d progression", i);
  newpr->SetDescription(buf);
  newpr->UpdateStatus(i);
  GetApplication()->PumpWaitingMessages(); // Yield
}

GetApplication()->GetMainWindow()->EnableWindow(TRUE);
newpr->Destroy();
delete newpr;

<H4>Subject: Using Dialog as Main Window</H4><PRE>
Hi,

  I'm thinking about porting a Visual Basic application to VC++ 1.5.
  The main form of the VB application has lots of controls in it,
  which would be tedious to layout at runtime in a VC++ CFrameWnd.
  I would much prefer to do the layout with AppStudio, which means
  that the main frame has to be a dialog box, right? So, is it
  possible to make a dialog box the main window of a VC++ application?
  Can this dialog box support a menu bar, toolbar, status bar etc like
  a CFrameWnd?

  Any suggestions much appreciated.

Regards

Check out the book "Inside Visual C++" 2nd ed.  by David J. Kruglinski, 
from Microsoft Press.  ISBN: 1-55615-661-8.

It has some code to do this.  Basically, in your C...App::InitInstance() 
you put a myDialog.DoModal() statement.  A few other things as well.  For 
details, consult the book.

I wrote a dinky little program once which was something along those lines. I'm
assuming the dialog window would be defined in a .RC file.  Hope this is what
you mean.

Hmmm... now let me see, the class registration stuff was like this, don't forget
the extra memory block in cbWndExtra.

        wndclass.style = CS_HREDRAW|CS_VREDRAW;
        wndclass.lpfnWndProc = MainWndProc;
        wndclass.cbClsExtra = 0;
        wndclass.cbWndExtra = DLGWINDOWEXTRA;   // THIS IS IMPORTANT
        wndclass.hInstance = hInstance;
        wndclass.hIcon = LoadIcon(hInstance, szAppName);
        wndclass.hCursor = LoadCursor(NULL, IDC_ARROW);
        wndclass.hbrBackground = GetStockObject(WHITE_BRUSH);
        wndclass.lpszMenuName = "MENU_1";
        wndclass.lpszClassName = szAppName;

        RegisterClass(&wndclass);


Create the window like this. Where `DIALOG_1' is your resource script.

        hMainWnd = CreateDialog(hInstance, "DIALOG_1", 0, NULL);
        ShowWindow(HMainWnd, nCmdShow);


In your message loop you'll need to filter out messages which are for the dialog
window. Otherwise you won't be able to traverse between child windows using the
tab key.

        while(GetMessage(&msg, NULL, 0, 0)) {
                if(!IsDialogMessage(hMainWnd, &msg)) {
                        TranslateMessage(&msg);
                        DispatchMessage(&msg);
                }
        }



Messages from the Child Windows can be read via the WM_COMMAND.  You could have
used a dialog procedure in the CreatDialog call to read these messages.

        case WM_COMMAND :

                switch(wParam) {

                case ID_OK :
                        /* DO SOMTHING */
                        break;

                case ID_CANCEL :
                        PostQuitMessage(0);
                        break;

                }
                break;

The static frame control in the dialog editor's tool palette is the
one showing the "picture" in the top right corner, next to the "Arrow".
You are correct in saying that this is not at ALL obvious!

I had this problem...received a solution Friday and just tried it
this morning, and it works.  Can't send a thanks to the guy yet
'cause I saved his reply at home...but thanks!

The solution:  Go to your link options in the Project | Settings dialog.
At the bottom are a bunch of options.  Select one of your targets,
and change the:

/SUBSYSTEM:windows

to:

/SUBSYSTEM:windows,4.0

Rebuild and run.  I could've figured that out if I wanted to (Yeah, right!)
Gotta love the 'net.
