CMFCButton ToolTip not working as planned

Hello,
Im trying to add tooltips to a dialog:

My code,which is in OnInitDialog

C#

m_FinishBitmap.LoadBitmap(IDB_ICON_FINISH1);
   CMFCButton *pFinish = (CMFCButton *)GetDlgItem(IDC_BUTTON_MEASURE_FINISH);
   pFinish->SetBitmap(m_FinishBitmap);
   pFinish->SetTooltip(_T("Finish Feature"));

error message:

_AFXWIN_INLINE HWND CWnd::GetSafeHwnd() const
{ return this == NULL ? NULL : m_hWnd; }

The problem is that the software hangs with this debug message because the dialog doesnt get initialized until you start using the software.

If I comment out the SetToolTip line everything is fine.

Please help Im really stuck

Thanks
Derrek

This is just a guess but you probably aren't calling __super::OnInitDialog() or UpdateData() before the code you provided.

The 4 lines you present here should be called after doing that, not before.
