This part of the series went through how we dynamically create the parameters for a Crystal report in our DNN module.  I believe there is a lot of potential for an application like this, and hope to extend it even more once the series is over.  I will expound more on how this might get done in the last part of our series.  Hopefully this series helps when you are trying to integrate with DotNetNuke or any other asp.net framework.   Happy Coding!
