Thread: Creating a window from a dialog box

Hi everyone,

I have a program which has a dialog box as its main menu, and as such, my WinMain looks like this:

Code:

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow)
{
return DialogBox(hInstance, MAKEINTRESOURCE(IDD_MAINMENU), NULL, MainDlgProc);
}

This means that I don't have a message loop and I don't register any window classes. However, on my dialog box, I want to have a button which launches a window when pressed (not another dialog box) and of course this window requires a message loop. So, my question is: is it possible to create a window from a dialog box? Where should I put the message loop?

Thanks!

Well, you probably don't want to return the value returned from DialogBox to main. From what I think, when you return from main you end the program. The return from main is the exit point of the program, the point of no return. Also, whatever value returned that is no 0, is probably seen as an error. The way I believe it can be done is just by creating window(s) like you would normally do, except you don't use ShowWindow. You only show the windows when you receive a command from the dialog.
