I don't know to access .NET assemblies from COBOL on Windows, I am the beginner on that. But if you know about how to access .NET assemblies from COBOL, then it is not a big deal to integrate Crystal Report. From .NET, there are 2 ways to use Crystal Report. One is pulling method, the other is pushing method. Pulling method is a little simple, you design Crystal Report with SQL Query and Data Source, saved them in rpt file. When you run the report, rpt file will pull data automatically from database and generate the report. Pushing method is, you design the report with .NET dataset object. no SQL Query and Data Source saved with rpt file. When you run the report, you need to get the data from .NET code first, then push data into rpt file and generate the report. I will suggest using pulling method at beginning. later on you might need to figure out how to get .NET dataset in COBOL and pass it into rpt file when using pushing method.
