How to use SetClassLong?

[Mike LaFlamme]

Should this work? I've never used these functions before and they don't seem
to be doing anything for me. I want to change style of the window from being
WS_OVERLAPPED to WS_POPUP and make the menus disappear. Basically I'm having
it go into a fullscreen mode but the damn menu bar and menus are still there
when I do this and I figure this is the way to fix this.

SetClassLong(hWnd,GCL_STYLE,WS_POPUP|WS_VISIBLE|WS_MAXIMIZE);
SetClassLong(hWnd,GCL_MENUNAME,NULL);
RedrawWindow(hWnd,NULL,NULL,RDW_FRAME|RDW_ERASE|RDW_INVALIDATE);

Some styles can be set dynamically, others can not be set
dynamically. I'm not sure which are in each category.

If it doesn't work dynamically, you should retrieve the current
size & location of the window, destroy it and create another
one in its place, with the new style and same size/location.

Try calling SetWindowPos with flags set to SWP_NOMOVE | SWP_NOSIZE |
SWP_NOZORDER | SWP_FRAMECHANGED after changing the style.
Also, use SetWindowLong instead of SetClassLong if you just want to alter 1
window.
I would have thought that changing the default menu name of the window class
would have no effect on any existing windows in that class. Use
SetMenu(hWnd,NULL) to get rid of the menu.

WS_POPUP, WS_VISIBLE, and WS_MAXIMIZE are window styles not class
styles. Use SetWindowLong to set these styles:

SetWindowLong(hwnd, GWL_STYLE, WS_POPUP | WS_VISIBLE | WS_MAXIMIZE);

Um, class style are things like CS_VREDRAW. WS_POPUP is a window
style, not a class style. You want SetWindowLong to modify a
window style.
