Hi,

In our application we use the ON_UPDATE_COMMAND_UI message and in its handler we change the text of menu based on certain conditions.
The exisiting code is -

void CSaIsApp::OnUpdateAppAbout(CCmdUI* pCmdUI)
{
if (pCmdUI->m_pMenu)
{
if(some_condition)
{
CString strMenuText = LoadString( SA_SUBSYSTEM_BRAND);
pCmdUI->SetText( (LPCTSTR) strMenuText );
}
}
}

In the above method pCmdUI->m_pMenu is NULL and hence we cannot use it.

Please suggest an alternative for this.

Thanks,
Sachin

Thanks, but I have another problem.

We have exisiting code for removing menus from menubar in the ON_UPDATE_COMMAND_UI handler.
The code we have is -

if (_some_ _condition_)
{
CMenu * pMenu = pCmdUI->m_pMenu;

UINT nStateAbove = pMenu->GetMenuState(pCmdUI->m_nIndex-1, MF_BYPOSITION);
UINT nStateBelow = pMenu->GetMenuState(pCmdUI->m_nIndex+1, MF_BYPOSITION);
pMenu->RemoveMenu(pCmdUI->m_nIndex, MF_BYPOSITION);

if (nStateAbove & nStateBelow & MF_SEPARATOR)
{
// Separator(s) must be removed since the menu choice was removed.
if (nStateAbove != (UINT)-1)
pMenu->RemoveMenu(pCmdUI->m_nIndex-1, MF_BYPOSITION);
else if (nStateBelow != (UINT)-1)
pMenu->RemoveMenu(pCmdUI->m_nIndex, MF_BYPOSITION);
}
}

How do I handle this in menubars derived from CExtMenuControlBar?

Please read Constructing Menus Dynamically at Run Time. You can use the described technique for modifying menus as well.

The pCmdUI->m_pMenu property is NULL because Prof-UIS menus are not based on Windows menus. You can change text without analyzing this property.
