Re: Send message issue

Hi David and Scotts,

Thanks for your response.I could get the concept of using SendMessage()

I used the function and I get an assertion which says the window is
null.

CView->Tabctrl->Dialog->CCMyListCtrl.mv->SendMessage(WM_INSERT_ITEMS,0,0);

//mv->m_myCtrlTab.userDlg->m_myListStudy_user_Ctrl.SendMessage(WM_INSERT_ITEMS,0,0);

How should I get the window to be not null.
Since Every control is subclassed ,I declared the variables in CView
CMyTabCtrl is a variable of CView
CMyDialog is a variable of CMyTabCtrl
CMyListCtrl is a variable of CMyDialog

Where am I going wrong
I get an assertion in the file afxwin2.inl line 43

AFXWIN_INLINE LRESULT CWnd::_AFX_FUNCNAME(SendMessage)(UINT message,
WPARAM wParam, LPARAM lParam)
    { ASSERT(::IsWindow(m_hWnd)); return ::SendMessage(m_hWnd, message,
wParam, lParam); }
