I create Excel Book as an object from VB application. After that I need to close it and delete all its objects from memory. I tried:

objExcel.Quit
set objExcel = nothing



Book disappears, but Excel Main Window is still sitting in a memory (I'm checking it with Task Manager).
I tried

lngReturn = FindWindow("XLMAIN", vbNullString) '"XLMAIN"-is the name of Excel Window Class
lngReturn = PostMessage(lngReturn, &H10, 0, 0)



The same result - Excel disappears but continue to sit in a memory.
How can I stop Excel and clean a memory.
Thank you.
