Finding a specific excel workbook **Resolved**

Hello

I'm trying to test if a specific excel workbook (which will always be named "Tax Invoice.xls") is already open as to not create multiple instances. I've been messing around with "FindWindowEx" and can determine if Excel is running but this is not quite what i want since other workbooks may be open at the same time for other purposes.

All i really need to do is stop "Tax Invoice.xls" from being opened more than once (from the app anyway).

Could someone please point me in the right direction. Thank you.

Ahh crap

Sorry nevermind i figured it out. Just needed the extra parameter.
Why do i always find the answer after i give up ;)
