Migrating an Excel VBA Add-in to a VB.Net XLL with Excel-Dna: update

This document has now grown to a 51 page tutorial.  Comments and corrections are requested.

I am providing a free addin QualifyVBACode. It takes the VBProject in a workbook and qualifies the xl constants with their enum types, and prefixes ones like ActiveSheet with Application. The search/replace strings are in a XML key/value config file that you can edit. Of course, please read the ReadMe.txt file first after unzipping this (XLL, DNA, DLL, CONFIG) :

    This is growing into a very nice and comprehensive guide – thanks for the effort, Patrick!
    (There is something wrong with the link to the document – the displayed text is correct, but when clicked on it goes to some ftp site.)

  2. Pedie Nz says:

    Is Excel-Dna used along with Visual Studio?
    Do i need to install this separately? is it cost involved?

    • sysmod says:

      It can be used with full VS. Or, VS Express, or SharpDevelop, both free.
      This is explained in the document. Try the exercises in order and come back with any questions that need more explanation.
