All the sample code always saves the windows layout to the registry on exit - I would like to do it on command (e.g. button press).

I know that the call to ProfileBarStateSave() does the save, but I cannot take it out of DestroyWindow() and put it in say - "OnSaveLayout()", which gets called from a button press.

Specifically, the code snippet:

Your code snippet looks correct. It must save the bar state to the registry and can be used in your OnSaveLayout() method. Please clarify the following: "... but I cannot take it out of DestroyWindow() and put it ...". Please let us know what exactly you cannot do?

I cannot move the CExtControlBar::ProfileBarStateSave() call out of DestroyWindow() and use it in the OnSaveLayout() method. I end up with an exception in ProfileBarStateSave() at line "ASSERT( ::IsWindow(hWnd) );".


-------------------code snippet ------------------

void CMainFrame::OnSaveLayout()
{
        CWinApp * pApp = ::AfxGetApp();
        ASSERT( pApp != NULL );
        ASSERT( pApp->m_pszRegistryKey != NULL );
        ASSERT( pApp->m_pszRegistryKey[0] != _T(’\0’) );
        ASSERT( pApp->m_pszProfileName != NULL );
        ASSERT( pApp->m_pszProfileName[0] != _T(’\0’) );


            VERIFY(
                CExtControlBar::ProfileBarStateSave(
                    this,
                    pApp->m_pszRegistryKey,
                    pApp->m_pszProfileName,
                    pApp->m_pszProfileName,
                    &m_dataFrameWP
                    )
                );
    
}

Your code should try to save the state of resizable bars only when the main frame window and all its bars are valid, existing windows. This means CWnd::m_hWnd properties of main frame window and all the bar windows should specify valid window handles. You cannot invoke the OnSaveLayout() method from the CMainFrame::PostNcDestroy() method. You cannot invoke it when CMainFrame is already destroyed. Please check these issues.
