I am using the following code to shut down a window using the escape key. I want to only have the escape key shut down the window but for some reason this code shuts down the window no matter what key I press.

	case WM_KEYDOWN:		
		if(wParam==VK_ESCAPE)
		{
		PostQuitMessage(0);
		break;
		}

I have tried the WM_CHAR message as well but to no help.

Hi Phil,

Take note of the location of your break statement here. If any other key is pressed, then the break statement isn't reached, and the code falls through to the next case statement, which I am assuming also has a PostQuitMessage. For example:

int i;
cin >> i;
switch ( i ) {
case 0:  cout << 'A';
case 1:  cout << 'B'; break;
}

When i is 0, "AB" is printed.

cool thanks that really helped, sometimes I need another pair of eyes to look at my code.
