I have found the web site of GR Business Process Solutions , who is offering a free add-in that allows the hiding and unhiding of multiple sheets (see http://www.grbps.com/ExcelB.pdf).
This is indeed a very nice and useful add-in, but it only has one snag: it is showing ALL the hidden sheets, including those who are VERY hidden.
I have tried creating some sort of loop that will identify the VeryHidden sheets and skip them (because those sheets are meant to remain really hidden from the users of the workbook) but failed.
Can someone help me out with such a modification to the code?
All the best, and thanks in advance
