I'm guessing that it's the worksheets that you can't display since they
are not visible to the user in an add-in. All you need to do to see these
is change the workbook's IsAddIn property to False as follows.
- Open the VBA editor.
- In the Project window select the add-in's ThisWorkbook object.
- Press F4 if the Properties window is not already open.
- Change the IsAddIn property to False.

i created a .xla-file out of a .xls-file which give me the advantage to run
the macros stored in the .xla-file in (nearly) every excel file. so far so
good.

the worksheet in the .xla-file contains important information. if i want to
change that information i have a problem: i can't enter that sheet
anymore...!

does anyone know how to convert that file back to a .xls-file? i can't
believe that .xls - .xla is an one-way-road!

TIA Walt
