I've investigated code and cant find any place to intercept internal string members and substitute with my own.

 

Initial values are assigned in the ctor:

 

CXTPDockingPaneWindowSelect::CXTPDockingPaneWindowSelect(CXTPDockingPaneManager* pManager, BOOL bActivatePanes)
    : m_pManager(pManager), m_bActivatePanes(bActivatePanes)
{
    ..............
    m_strActiveTools = _T("Active Tool Windows");
    m_strActiveFiles = _T("Active Files");
    ..............
}

and window itself is created and shown without any additional notifications:

 

LRESULT CALLBACK CXTPDockingPaneKeyboardHook::KeyboardProc(int code, WPARAM wParam, LPARAM lParam)
{
    ...................
            CXTPDockingPaneManager* pManager = pKeyboardManager->FindFocusedManager();
            if (pManager && (pManager->IsKeyboardNavigateEnabled() & xtpPaneKeyboardUseCtrlTab))
            {
                pWindowSelect = new CXTPDockingPaneWindowSelect(pManager, FALSE);
                BOOL bResult = pWindowSelect->DoModal();

 

                delete pWindowSelect;
                pWindowSelect = 0;

 

                if (bResult)
                    return TRUE;
            }
    ....................
}

I afraid not. We will move this strings to resources for next update release. Thank you
