I need to create an MDI Child with a thin frame i.e. not resizable.
I have managed to do this by manipulating the window STYLE after calling with START_MDICHILD - after and not before, as START_MDICHILD flips it back to the MDIFRAME style. This appears to work fine until I minimize then maximize the frame. What happens then, is that the Child displays a 1 pixel transparent border within the Child border. Yuk!
I have overcome this by starting the Child minimized and then calling SHOWWINDOW. This solves the problem, but there is a delay between the Child appearing in the frame minimized and the Child being displayed normal, not very elegant. Is there a better way of doing this?
