Thread: Unable to lock Dialog

When a user is actually moving a window, the OS sends your processing loop WM_MOVING messages and when the move is complete, a WM_MOVE message. You can process these yourself to do whatever you like.

You can use MoveWindow() to move a window around.

Users tend to move windows because they want to. Windows is designed like that. By changing the behaviour of your windows, your app will not feel like a proper Windows app. People don't like that. You should be really sure you need to do this before trying.

I do some thing like this,

When the Dlg is created I get the screen coods in a RECT (CRect ect)

Then I stop the user being able to start to move it. By changing the move msg as it passes in the callback.

Code:

case  WM_MOVING:
((RECT*) lParam)->left= rScreenRect.left;
((RECT*) lParam)->right= rScreenRect.right;
((RECT*) lParam)->top= rScreenRect.top;
((RECT*) lParam)->bottom= rScreenRect.bottom;
break;
