MFC, enable/disable toolbar button using pCmdUI->Enable(TRUE/FALSE) doesnt work

enable/disable toolbar button using pCmdUI->Enable(TRUE/FALSE) doesnt work

Author	Message
John #1 / 7	enable/disable toolbar button using pCmdUI->Enable(TRUE/FALSE) doesnt work I tried to enable and disable some buttons using the command ui handler by invoking the Enable() function "but it only enables/disables the menu item" and "not the toolbar itself". I'm doing this inside a View (which I don't see any reason why it shouldn't work). Any ideas what I might be missing here? TIA, John http://www.--*.com/ SDI Win2K VC++ 6.0

Ajay Kalr #2 / 7	enable/disable toolbar button using pCmdUI->Enable(TRUE/FALSE) doesnt work As you suggested, it should work. Make sure of the ID and message map entry. If you are using SDI, then placing the ON_UPDATE_COMMAND_UI handler in view should be OK. -- Ajay Kalra [MVP - VC++] Note: Please post all replies to newsgroup only.

John #3 / 7	enable/disable toolbar button using pCmdUI->Enable(TRUE/FALSE) doesnt work thanks Ajay for your quick response. However, it still doesnt enable/disable after the Enable() call. I did try the SetCheck() and I can see the button state change (pressed/unpressed state). Anyway, I'll try the MainFrame (im gonna change the program flow to access data on my mainframe instead the view from the main document though.... really ugly). thanks again, John Quote: > As you suggested, it should work.

Ajay Kalr #4 / 7	enable/disable toolbar button using pCmdUI->Enable(TRUE/FALSE) doesnt work The ID might have been used multiple times and somehow the other handler is overriding it? -- Ajay Kalra [MVP - VC++] Note: Please post all replies to newsgroup only.

John #5 / 7	enable/disable toolbar button using pCmdUI->Enable(TRUE/FALSE) doesnt work That's the first thing I checked actually.... from mainframe, document, view... and even the main app, I'm sure its being routed to only 1 ui command handler. Anyway, I think I found out why... I think I need to force call the command UI handler. The UI handler never gets called when I changed the status of the button so I can start from there for now (i know... if the SetCheck() were being called without any force updates...why not the Enable()?). Any message I can send to force call it?

Ajay Kalr #6 / 7	enable/disable toolbar button using pCmdUI->Enable(TRUE/FALSE) doesnt work You can force it by calling AfxGetApp()->OnIdle(-1). But it should be called regardless. You can do it at the same time when you do SetCheck. -- Ajay Kalra [MVP - VC++] Note: Please post all replies to newsgroup only.
