I kow I should know how to do this but can someone show me how to use the following code with a button to print my DataGridView please?

Private oStringFormat As StringFormat
Private oStringFormatComboBox As StringFormat
Private oButton As Button
Private oCheckbox As CheckBox
Private oComboBox As ComboBox

It is from a previous post by Hannes in a thread about printing DataGridViews.

Thanks in advance ;)

before doing it you should check that YourBrain IsNot Nothing, then enclose the procedure on a safe Try...End Try block. :ehh:
