Project Automation

Yes, Sometimes i do project automation and believe me its not as easy as it is in Word or Excel the basic problem here is there is no add-in concept so i had to create an application that adds the command bars and then hooks the events every thing seems working but unfortuantely it doesn't work...!! the error i get (generally..) is "Call reject by callee", i know this error is generally thrown when app is busy, but its busy in what..??? i just hooked one event..! Finally i thought i need the help of some project gurus so posted my query to larry's blog on if he doesn't have a way, then god help me ..!!
