Using a chm file – here is how (scroll waaaaay down) to link your help file and your function. I want to do this pro grammatically and generate a link automatically. We will see how that goes.
Did you know you can get all of your VBA code extracted to a text file procedure by procedure (using VBA itself?) I made an export tool for all my modules, but I always wanted to add help like they do in c# (sandcastle style) and link to a help file. Check this link. I have so much code now I am going crazy.
