Possible to change window style after creation?

[conman110]

My question is, if it's possible to change the style (dwStyle) and the extended style (dwExStyle) of a created window. I am working on a window that is a normal OVERLAPPEDWINDOW but when I switch to fullscreen it should be a POPUP etc. Do I have to Destroy and create a new window? Thanks! Constantin

Did you try ModifyStyle() and ModifyStyleEx()?

Oh! you see I am not very used to MFC and didn't find it myself :) Guess that's what I searched. I'll try it... Thanks! Constantin
