I'm working on an application that creates its main menu using "CreateMenu()" before the window is created. This way I can stay away from VS2005's bloated resource files. The thing is, when I close out the program, I want to know that all of my resources are freed to avoid memory-leaks, but I am not sure if I am freeing the menu properly or not. I am using "DeleteMenu()" to attempt to delete the entire menu and sub-menus in one quick, easy call. The MSDN says that "DeleteMenu()" will do this, but I am not sure whether or not I am calling it correctly to do so.
//See if the menu needs freeing
if(this->hMainMenu != 0)
DeleteMenu(this->hMainMenu, 0, MF_BYPOSITION);
That is in the class method for cleaning up my prorgam. I am assuming that specifying position zero will delete everything from that position on. Is this correct?
After a few hours of searching I found out that to free a menu, you must call "DestroyMenu(HMENU)". This takes care of all items on the menu, but not sub-menus. You should destroy all sub-menus first, then the parent menu.
