Hi,

Catch WM_XTP_GETWINDOWTEXT message in CChildFrame and reeturn (LPCTSTR) points to Tab Caption you need.

Hi Oleg,

I have implemented a message handler as you suggested, but the compiler constantly tells me that he cannot convert from LPCTSTR to LRESULT.

So, what's wrong with my code below?

Heiko

LRESULT ChildFrame::OnGetTabText(WPARAM /*wParam*/, LPARAM /*lParam*/)
{

MyDocument* pDoc = dynamic_cast<MyDocument*>(GetActiveDocument());

if (pDoc != NULL)

{

m_strTabTitle = pDoc->GetText();
return (LPCTSTR)m_strTabTitle;

}
return 0;

}

Hi Heiko;

You have to cast m_strTabTitle to LRESULT not to LPCTSTR!

The sender of the message knows how to interpret the LRESULT param - in this case its a const pointer to a string.

try

return reinterpret_cast<LRESULT>(m_strTabTitle);

or if m_strTabTitle is of type CString

return reinterpret_cast<LRESULT>(reinterpret_cast<LPCTSTR>(m_strTabTitle));

You can do it also in old C style... return (LRESULT)m_strTabTitle

Thanks Martin,

the cast (LRESULT)((LPCTSTR)m_strTabTitle) works. Maybe the help-topics of WM_XTP_GETWINDOWTEXT and WM_XTP_GETWINDOWTOOLTIP should be updated.
