Everything compiles fine (should do what I want right!):) but the indicated line below fails to put the CString into the CWord.

      CFlexCheckDoc* pDoc = GetDocument();
      CString sTemp=pDoc->m_sFlexData;
      CString sTTemp;
-->      CWord wWord=sTemp;
When I make the change as follows the assignment works fine
      CFlexCheckDoc* pDoc = GetDocument();
      CString sTemp=pDoc->m_sFlexData;
      CString sTTemp;
      CWord wWord;
      wWord=sTemp;
I am looking for some one who can break it down for me why this is happening.  You know not repeat the same mistake.

Thanks Guys.
