Getting OnUpdateCmdUI events to fire on time in a CDialog based application.

[M. J. Eggertson]

This isn't specifically NI related (though it is a problem I've run into while developping instrument control software with MStudio).

Evidently I've never tried to construct a Dialog based app before in MSVC++/MFC with menus. I have my main app window derived from CDialog, and I added a menu to it. The menu events fire fine, and the OnUpdateCmdUI events fire too. But here's the catch: the ON_UPDATE_COMMAND_UI events fire immediately before the item ON_COMMAND events (ie: not when the menu is first displayed, but after an command has been clicked).

How do I ensure that the menu is updated normally? You know, so check and radio settings actually appear (the way they do in frame windows)?


Thanks for any advice,

This is an MFC problem and is solved by John Wismar in it's article "Handling OnUpdate() processing for menu items" posted on Code Guru (http://www.codeguru.com/dialog/OnUpdate.shtml).

Hope will solve your problem,
