I have two DockingPanes, and I need to change the Controls of these DockingPanes at Main Menu:

Maybe there are two AFX_IDW_PANE_FIRST:

CSearchOptionsView* CMainFrame::GetSearchOptionsView()
{
CXTPDockingPane* pPane = m_paneManager.FindPane(IDR_PANE_OPTIONS);
if (!pPane)
return 0;
CWnd* pWnd = pPane->GetChild();
if (!pWnd)
return 0;

return (CSearchOptionsView*)pWnd->GetDescendantWindow(AFX_IDW_PANE_FIRST);

}

CPaneChat* CMainFrame::GetChatView()
{
CXTPDockingPane* pPane = m_paneManager.FindPane(IDR_PANE_CHAT);
if (!pPane)
return 0;
CWnd* pWnd = pPane->GetChild();
if (!pWnd)
return 0;

return (CPaneChat*)pWnd->GetDescendantWindow(AFX_IDW_PANE_FIRST);

}

Here is the code from your sample "Grep"

When I click Main menu - Edit - static and Edit - test ,it crashed.

please tell me why?Oleg https://forum.codejock.com/uploads/20070117_104737_Grep.zip - uploads/20070117_104737_Grep.zip

void CMainFrame::OnEditTest()
{
CPaneChat* pChatView = GetChatView();
pChatView->OnChangeStatic();

}

check that pChatView not NULL before call its method.

View will be NULL before become visible first time.
