I have developed extensive Excel 2003 VBA addins. I'm planning my Excel
2003 - 2007 upgrade and have a couple general questions to start with:

1. Will Excel 2003 addins work in Excel 2007?

I hope I can load my 2003 addins in Excel 2007, save them and
reuse the saved version.
If things have changed, is there a list of items which have changed?

I use the addins to create reports. For example, I create a
customized excel menu from a table to access my specialized functions,
insert
excel worksheets and update the excel names when the worksheet is inserted
to use the parent workbook's names, have implented a 2d sketch package on
top of the excel drawing functions, etc. In general, my addins would be
considered advanced VBA usage.

2. Is there a method in Excel 2007 to prevent users from accessing the addin
contents?

I want to distribute my addin's, but I want to keep the addin contents
private.
In Excel 2003, you could add a password but there are numerous tools which
will crack your password. There was no way to keep the addin contents
private.
I was hoping for a compile/binary option in Excel 2007 to keep the addin
contents private.

thanks.

I haven't fully delved into Excel 2007 yet, but I have this list of
compatibility articles bookmarked:

1. Will Excel 2003 addins work in Excel 2007?


Some do, some dont: the only way to find out is to try them out. The number
of fundamental changes made to Excel 2007 is large, not to mention the way
the addin eui has been changed (you will have to think about whether you
should develop a new end-user interface for your addins, or whether your
users can tolerate all the addin menus and toolbars appearing in the addins
chunk of the ribbon).


2. Is there a method in Excel 2007 to prevent users from accessing the
addin
contents?


I do not see any improved security for VBA addins in Excel 2007.

Thanks for the info. The Excel VBA 2003 - 2007 conversion appears to
require more work than I was hoping.
