WM_MOUSEMOVE problem | GameDev.net

I have an OpenGL window where the coordinates of the pointer are printed to the screen. The problem is when the cursor is not moving (of course) I don''t get the message therefore my coordinates are not displayed anymore. Does anyone have a work around for this...Its probably quite easy but I''ve been staring at the screen to long to see it! I was thinking since I have a SwapBuffers() call it might not work right. I wasn''t clear to explain, but as long as the cursor is over the window...moving or not, I would like the coordinates displayed as shown below... Here is some code.

case WM_MOUSEMOVE:
		xmouse = LOWORD(lParam)-(w/2);
		ymouse = -(HIWORD(lParam)-(h/2));
		TextOut(hLDC, 0, 0, szBuffer, 
			wsprintf(szBuffer, TEXT("x:%i y:%i"), xmouse, ymouse));
		
		break;

Store the x and y positions in global variables then draw the text of their location each frame. Use WM_MOUSEMOVE to update the locations.

Hey, thanks...that worked pretty good. Only problem is if flickers with the refresh of the window. I may need to find some other way of displaying the coordinates.
Thanks
