how do u even do that ----- Original Message ----- From: rick watson To: programmingblind@xxxxxxxxxxxxx ; BlindGeeks@xxxxxxxxxxxxxxx Sent: Tuesday, April 14, 2009 12:28 PM Subject: building a dll using a wizard Good afternoon listers, Has anyone attempted to use a wizard to build a dll from cs source files. What I need is to add a bunch of .cs files to a project, change some method names in these files and then build a .dll Is a wizard the best way to accomplish this. The only things that I know are: 1. Some of the .cs files will be the same every time. 2. Some will be different. Currently we have a bunch of dlls based on names such as mapinvoice and mapcreditmemo. What I want is one dll which calls methods for these functions. These source files are being generated by another program. Thanks for any advice. Rick
