Use GetSystemMenu to access the Control menu for copying and modification. The GetMenuItemCount function determines the number of items in the specified menu. The RemoveMenu function deletes a menu item from the specified menu. The DrawMenuBar function redraws the menu bar of the specified window. It should be easy to compile them together.<br />
Or simpler:<br />
CMenu *MyMenu; MyMenu = GetSystemMenu(FALSE);<br />
&nbsp;MyMenu-&gt;EnableMenuItem(SC_<wbr />CLOSE,MF_D<wbr />ISABLED);<br />

Is there any way to disable (or even hide) a window caption's close button, i.e. the top right button of a ws_sysmenu style window. I can already prevent a window from closing, so that is not what I'm asking for.<br />
I have seen MDI child windows with this button disabled, so there has to be a way?!<br />
Since I don't ask a lot of questions, a good answer will be worth a bunch.<br />

Disabling close button

Kernel and system programming is the process of creating the software necessary for a computer or device to function and operate other programs. Some operating systems (such as Microsoft Windows) are proprietary, but others, such as the various Linux distributions, are open source.
