Hi,

I want to change (insert or delete item) the popup menu of a CXTPControlPopup dynamically. I use the following code below, but everytime I am trying to get access to the popup menu I assertion error. Any Ideas ?

m_pPopupHistory = (CXTPControlPopup*)pGroup0->Add(xtpControlButtonPopup, ID_POPUP_HISTORY);

pPopupBar = CXTPPopupBar::CreatePopupBar(GetCommandBars());

m_pPopupHistory->SetCommandBar(pPopupBar);

m_PopupHistoryMenu.LoadMenu(IDR_MENU_HISTORY);

pPopupBar->LoadMenu(m_PopupHistoryMenu.GetSubMenu(0));

pPopupBar->InternalRelease();

...........................................................

//somewhere in my code

CXTPPopupBar *pChildBar = (CXTPPopupBar*)m_pPopupHistory->GetCommandBar();

CMenu *mm = pChildBar->GetMenu(); // <-- At this point I get assertion error

mm->AppendMenu(MF_STRING, 1, "Text 1");

pChildBar->InternalRelease();

Hi,

Can you please provide a small sample application so that we could debug this issue?

Make sure that pChildBar is not NULL and also really belongs to CXTPPopupBar class.

Thank you.

Thanks for the reply.

I can verify that pChildBar is not null. I attach the original sample "Ribbon Controls" where I added my offended custom code at line number 524 inside the MainFrm.cpp.

Thanks

CXTPPopupBar *pChildBar = (CXTPPopupBar*)pCustomPopup->GetCommandBar(); 
CMenu *mm = pChildBar->GetMenu();  // <-- At this point I get assertion error

but pChildBar->m_hWnd is NULL that is why assertion fired

CMenu* CWnd::GetMenu() const
{
	ASSERT(::IsWindow(m_hWnd));
	return CMenu::FromHandle(::GetMenu(m_hWnd));
}

pPopupBar->LoadMenu(mmenu.GetSubMenu(0)) converts menu items to command bar controls. That is why you can't get CMenu which was loaded.
But you can use

pChildBar->GetControls()->Add();
pChildBar->GetControls()->InsertAt();
pChildBar->GetControls()->AddMenuItem();
pChildBar->GetControls()->AddClone();

pChildBar->GetControls()->MoveBefore();

Fro example:

CXTPPopupBar *pChildBar = (CXTPPopupBar*)pCustomPopup->GetCommandBar(); 
CXTPControl* pMenuItem = pChildBar->GetControls()->Add(xtpControlButton, ID_DYNAMIC_POPUP2 + 1);
pMenuItem->SetCaption(_T("Text 1"));

Hi,

Thank you for your quick response. I was suspicious with the LoadMenu() thing.

In fact, I thought that the pPopupBar->LoadMenu(xxx) may have suppressed the CMenu structure in some way since the way you showed me to solve the problem, was already tested and verified that it works just fine.....

I should check the source code before I ask... but you help was precious and saved my time !

Best Regards,
