MessageBox API

[Andrew Herrmann]

As I mentioned in an earlier post, I'm using the MessageBox API call to display a message before running a console application.

Unfortunately, this acts as a "modal" form within my application. In other words, I can freely access other Windows, but my console application will not continue execution until the message box is closed.

I tried to set the hWnd parameter to NULL and HWND_DESKTOP, but neither changes the behavior. Is there a way to keep the MessageBox on the desktop and allow my program to continue execution? Do I need to use a different API call?

Any help would be greatly appreciated..

MBAPPLMODAL - message box application modal is the default behavior. You need to use another kind of dialog box.

Any suggestions?

MB_OK would be good.

Create your own dialog template and dialog proc and use CreateDialog.
You must extend your message loop then:

while(GetMessage(&msg, NULL, 0, 0) > 0)
{
  if(!IsDlgMessage(hdlg, &msg))
  {
    TranslateMessage(&msg);
    DispatchMessage(&msg);
  }
}

hdlg is the handle returned by CreateDialog.

How about starting a new thread? That should allow the program to continue. Note that if the program finishes, the message box will automagically be closed.

Good idea. Like

DWORD MBThreadMain(LPVOID pVoid)
{
  MessageBox(NULL, "Hello", "Hello", MB_OK);
  return 0;
}

If you at one point want to stop until the messagebox is closed, use WaitForSingleObject
