Using Toolkit Pro 20.3, Visual Studio 2022, Windows 11.

When I enable tear off windows, tear one off, and then close the main client window the app will crash in CXTPTearOffFrame::DestroyWindow(). A bad pointer is returned from:

    CXTPTabClientWnd* pPrevTab = (CXTPTabClientWnd*)m_wndTabClient.m_lstPrevTab.GetHead();

If I close the tear off window first, then close the main client window I don't get the crash.

Anybody else seen this?  Is there a workaround?

Hello,

Unfortunately it is not clear what exactly is going wrong.
If it cannot be re-produced in any of our sample applications provided I would appreciate you sending a small code snippet or ideally a sample application so that we could debug it.

Regards,
Artem Gontarenko

I have the same issue with ToolKitPro 22.0.0. I was testing the sample project RibbonResource. 
Steps:
1. In function CMainFrame::OnCreate add one line m_wndTabClient.EnableTearOff(). 
2. Open a few tabs.
3. Tear-off one of opened tabs.
4. Close application.
5. We have crash mentioned in topic CXTPTearOfFrame::DestroyWindow().

This may or may not work for you. It works for me as of Toolkit Pro 20.3.0

In CMainFrame::OnClose(), I call CXTPTabClientWnd::CloseAllTearOffFrames().

My CMainFrame's CXTPTabClientWnd member is _MTIClientWnd.


void CMainFrame::OnClose()
{
    if(_MTIClientWnd.GetItemCount() > 0)
        _MTIClientWnd.CloseAllTearOffFrames();

    _MTIClientWnd.Detach();

    CXTPMDIFrameWndEx::OnClose();
}
