Disabling WM_Close

Hi, first i would like to thank everyone who helped me solve my compiler problem. Second, i would like to know how to disable closing the dialog box by pressing the X (close icon). I know that when i select how to handle WM_Close is when to disable it, but i'm wondering how. If i ignore it will it just do the default and close the program? Thanks in advance for your help.

just do

case WM_CLOSE:
return TRUE;
break;


or something like that

this should work! dont process WM_CLOSE in WndProc. the only problem is your program wont close unless use a menu item or something.

Code:

LRESULT CALLBACK WndProc(HWND hwnd, UINT Message, WPARAM wParam, LPARAM lParam)
{
	switch(Message)
	{
	case WM_COMMAND:
		switch(LOWORD(wParam))
		{
		// menu item
		case IDM_EXIT:
			DestroyWindow(hwnd);
			PostQuitMessage(0);

			break;
		}
		
		return TRUE;

	// try doing this for your default
	default:
		if(Message != WM_CLOSE)
		{
			return DefWindowProc(hwnd, Message, wParam, lParam);
		}
	}
	return 0;
}

In your WndProc, just add this to your WM_CREATE:

SetWindowLong(hwnd, GCL_STYLE, CS_NOCLOSE);

Why would you want to disable closing.

i want to disable it because i'm creating a login program, i want the only way for the dialog to be closed is through normal termination, ie:entering the correct password and clicking ok.
