Hello, I have a problem with the UIstate. We have a dialog that gets created at Oncreate in Mainfrm and it has a CExtGridWnd in it. We hide this until the user calls it up. The problem is that if it doesn’t get viewed it breaks all uistate files when trying to load them to change the GUI. If you view the dialog it doesn’t break the UIstate and you can load the state files, but if you don’t we get a break at DWORD rtPageStates = 0;
ar >> rtPageStates; in function:
void CMainFrame::DoLoadBarStateFromFile()
{
// begin prompting user
CFileDialog dlg(
        TRUE,
        _T("UI state"),
        _T(".\\Default.UI state"),

        _T("UI state files (*.UI state)|*.UI state|All files (*.*)|*.*||"),
        this
        );
    dlg.m_ofn.lpstrTitle = _T("Open UI state from file");
    if( dlg.DoModal() != IDOK )
        return;
    ASSERT( dlg.m_ofn.lpstrFile != NULL );
// end prompting user

Any help with this would be greatly appreciated.

Thanks in advance.

We are sorry but there is not enough information in your message to find out what’s wrong. What is RemoveExtControlBar()? We guess you should verify that the control state data contains exactly the same set of bar state descriptions which match the set of bars really created in the main frame window. This is essential requirement. If you need to make some of your control bars initially hidden in any case, then you should load bar states and then forcibly hide this bar. You should not remove/destroy it. You can set its CExtControlBar::m_bAppearInDockSiteControlBarPopupMenu property to false so this bar will not be present in any of built-in Prof-UIS context menus. As a result, the user will not be able to access this bar.
