Are you sure,
GetToolBarCtrlis returning some valid pointer. Probably, it is returingNULLvalue.mohindar_kks wrote:
(abnormal termination error are occure)
This statement leads to above guess.

I am not sure about the approach that u have specified here. But the following approach will server the purpose of enabling / disabling the tool bar controls. You need to add a function in your view class. For example… Add ON_UPDATE_COMMAND_UI(ID_FILE_NEW, OnUpdateFileNew ) at location shown. CMyView.cpp file ======================================================= BEGIN_MESSAGE_MAP(CMyView, CScrollView) //{{AFX_MSG_MAP(CMyView) other message handler functions... ON_UPDATE_COMMAND_UI(ID_FILE_NEW, OnUpdateFileNew ) other message handler functions... END_MESSAGE_MAP() Void CMyView:: OnUpdateFileNew(CCmdUI* pCmdUI) { if( some_Condition) pCmdUI->Enable(true); else pCmdUI->Enable(false); } CMyView.h file Public: void OnUpdateFileNew (CCmdUI* pCmdUI); Framework will keep calling OnUpdateFileNew function frequently and will keep the tool bar option enabled or disabled in a way u want.

You're getting a failed assert because
m_wndToolBaris just a C++ object, it's not a window so you can't use the methods that operate on the underlying toolbar window.--Mike-- Visual C++ MVP :cool: LINKS~! Ericahist | PimpFish | CP SearchBar v3.0 | C++ Forum FAQ Dunder-Mifflin, this is Pam.
