I have a workbook which contains all the text used by my Add-In. I use this
for localizing into other languages. My add-in opens this workbook and uses
it in conjunction with a GetString routine. I don't want this workbook to be
visible in the users Excel workspace. I accomplish this now by setting the
"IsAddin" property of my language workbook to True after I open it. A
problem with this is that if you try to open the language sheet - to
translate into another language - it does not show up - I guess because it
thinks it is an Add-In. Further - when you select Tools/Add-Ins - the
language sheet shows up as an Add-In. - but it is not really an Add-In per
say.

I may end up reading all the strings in once (there are not that many) and
not keeping the language workbook open. However, if you know of a cleaner
way to this - Workbook.Visible = False..Please let me know.

Thanks,
Steve
