1. Firstly I have sub-classed the winword with my windows procedure with appropriate sub-classing requirement (rules).
2. After sub-classing, from my own application i am sending WM_USER + 40 message with character 'x' to winword.
3. As i have sub-classed first this 'x' will come to my WndProc then i will do some operation on 'x' and processed 'x' will forward to original winwords 's WndProc. See following my WndProc
