argh, dialog resource menu enabling/graying

[Kuniva]

Hi, i've posted a message about this before and i got an answer but it wasn't what i needed. You see i need to know how i can enable/gray menuitems in a dialogs menu in MFC. The menu is pure resource, there isn't any code to add the menu to the dialog, i just clicked properties of the dialog and there is an option to select a menu resource for that dialog. Now my last answer was: use OnUpdateCommandUI i did this and then u get a pointer to the menuitem and then u can do something like this: pCmdUI->Enable(0); but thats just not what i need! the menuitem is disabled, i cant click it anymore but its not gray!!!! so u dont know its not working, i've also tried using ->SetText("blablabla") but that doesn't seem to have any effect whatsoever. Can someone please explain this all to me, and show me how to do it right? or give me a tutorial or something i can look at? Cause all the pages about menus on codeguru and the codeproject seem to be dealing with more advanced problems. Many thanks. Kuniva

1. Add a handle to your dialog.h like this: afx_msg LRESULT OnKickIdle(WPARAM, LPARAM); 2) Includes in the dialog.cpp (for WM_KICKIDLE) message 3) Insert this code into the MESSAGE_MAP ON_MESSAGE(WM_KICKIDLE, OnKickIdle) 4) Create the function OnKickIdle like this LRESULT ServerProperties::OnKickIdle(WPARAM, LPARAM) { CMenu* pMainMenu = GetMenu(); CCmdUI cmdUI; UINT n; for (n = 0; n < pMainMenu->GetMenuItemCount(); ++n) { CMenu* pSubMenu = pMainMenu->GetSubMenu(n); cmdUI.m_nIndexMax = pSubMenu->GetMenuItemCount(); for (UINT i = 0; i < cmdUI.m_nIndexMax;++i) { cmdUI.m_nIndex = i; cmdUI.m_nID = pSubMenu->GetMenuItemID(i); cmdUI.m_pMenu = pSubMenu; cmdUI.DoUpdate(this, FALSE); } } return TRUE; } 5) Add the handles to OnUpdateCmdUI to menu items. 6) Relax, compile it e enjoy. :cool: PS: That will work only for menus, there is a different way to handle toolbar.

The problem is that the update command UI system relies on the MFC message WM_KICKIDLE, which is not automatically handled by dialogs (it is handled by frame windows). The previous post has some code, however the OnKickIdle() can be done more simply:

OnKickIdle(...)
{
UpdateDialogControls ( this, FALSE );
}

The second parameter controls whether menu items without command handlers will be disabled. Pass TRUE to disable them, or FALSE to leave them alone. --Mike-- http://home.inreach.com/mdunn/ This posting is provided "as was" with no warranties, guarantees, lotteries, or any of those little bags of peanuts you get on planes.
