How to check if ANY excel workbook is open?

Question

I have a VBA project in excel which hides the workbook in the background and only shows the userform, it works fine however, causes problems when other workbooks are open as it

Answer 1

The ideal solution is not to force a multitasking Excel user to close all their workbooks in order to use the one with the user form, but to specifically address the workbook in your code so that it doesn't effect other workbooks. You can use ActiveWorkbook.FullName for this.
