Checking drop down toolbar menu items
-
I have a drop down menu on one of my toolbar buttons. I am having problem with checking menu items. If I use CCmdUI::SetCheck method, there is no problem, but I want to do this in a different way. Why does this code give error? int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct) { if (CMDIFrameWnd::OnCreate(lpCreateStruct) == -1) return -1; ... ... menu_tb2_btn1.LoadMenu(IDR_MENU_TOOLBAR2_BUTTON1); ASSERT(menu_tb2_btn1); pPopup = menu_tb2_btn1.GetSubMenu(0); ... ... return 0; } void CMainFrame::OnTb2btn1Item1() { // TODO: Add your command handler code here ... ... pPopup->CheckMenuRadioItem(0,3,1,MF_BYPOSITION); ... ... }

It's a run-time error. It says debug assertion failure. I defined a pPopup named object and tried to make it hold the drop down menu, so that I can easily have access to other functions. But unfortunately I couldn't do this.

As the assertion is related to a
CStringobject, the code snippet you've provided is of no help. You'll need to locate theCStringobject in question. Given thatm_pchDatais in error, my first guess is that it is a heap-based object.
