Technically, we aren't an ANSI-only list. There are just very few OS-specific questions asked because few people here can handle them. I tend to field the Windows-specific ones. To answer your question, I'm not sure what the proper answer is since I'm not sure what the menu structure itself looks like. You should be checking the return value of EnableMenuItem() to make sure it is returning something other than -1. Try not calling GetSubMenu(). Specify MF_BYCOMMAND even though it technically isn't needed (i.e. default). I assume you are using the menu as a popup and using TrackPopupMenu() or similar. If you are using it, say, as a "IDR_MAINFRAME" (doc/view) sort of menu, ON_UPDATE_COMMAND_UI(), even if not specified/declared/defined, could be overriding it (see the note in the comments on the webpage you provided). I use MFC quite heavily but I'm not a guru. The wonderful people over at www.codeproject.com in the forums seem to have nothing better to do all day but help other people out. That is a more Windows-centric environment worth checking out in addition to this group. Both this group and CodeProject are excellent resources for various aspects of C++ programming for Windows. BTW, good to see you've done your own research. Few people do that. -- Thomas Hruska CubicleSoft President Ph: 517-803-4197 *NEW* MyTaskFocus 1.1 Get on task.
