Thread: Over Rideing close message when closing window

I have a window and than I have a child of that window wich is just anouther window. (Not a special like a button). But when I close the child window it closes the main window as well and shuts down the process. Is it possible to make that not hapen and only cloes the child window, I was thinking overridding the wm_close message or somthing.

Maybe, don't call PostQuitMessage in the WM_DESTROY message for the child window?

Otherwise, could you post the code?

Ahh ok that worked great. It's amazing how people can't think of the simplest solutions.

I figured out that isn't working. The child window uses the class of the main window, so I'm not sure how to not call PostQuitMessage in WM_DESTROY of the child sence the WM_DESTROY gets sent to the same message proc.

Code:

if (hwnd == hwndParent) PostQuitMessage(0);

or, if you don't store the parent hwnd in a variable, you can just check if the hwnd is a parent window:

Code:

if (GetParent(hwnd) == NULL) PostQuitMessage();

ok but when I do that, no windows show up. But if I take out the if statment the windows show up. huh?

The if statement should be in the WM_DESTROY message:

Code:

case WM_DESTROY:
{
    if (GetParent(hwnd) == NULL) PostQuitMessage();
    break;
}

heres my code:

Code:

        case WM_DESTROY:
			if (hwndwindow == hwnd)
			{
				PostQuitMessage(0);
			}
            break;

were hwndwindow is the paramter in the callback and hwnd is my parent window.

You could also create a seperate class and wndproc for child windows.
