you can define them on top of your code, they will be accessible to all methods..
I am not sure if they all have to be global, what I mean is, for instance, you have an error message says:
"The name 'bFirstPage' does not exist in the current context "

I can see bFirstPage in couple places, but you never defined it as bool...Error message says bFirstPage variable is not defined..

@ali tuncer
please can you have idea to how to define them globally.

Thanx
ali tuncer10y ago
Did you define those variables?(iCellHeight,iHeaderHeight,strFormat..) I think you need to define them globally..
