Here's the thing, we are running in Unix OS environment. We have a program set to run WordPerfect. But now, we are trying to convert the WordPerfect to MSWord for Windows. We are going to use VB.net to run our merge letter program. I already have the datasource, the word document and a simple vb.net program to execute the merge. I have to run this vb.net program to execute different database and word document. I probably need to set up parameters but how do I do that?
