and When i double clicks (In Place activation), the documents gets activated (A WINWORD.EXE process is opened) and i can edit the document and in the button click event i am saving the document like this :

http://support.microsoft.com/kb/132003

and I could save the document.

But the WINWORD.EXE process is not closed and keeps running only in Word 2007. So when i run the same form next time, i couldn't access the template file and it says already opened. Please help me...

Thanks
