Use DataSet as datasource for Crystal Reports in C# 2005

Hello,

I am getting close to the deployment stage with a C# project and have run into a few snags. My project has many Crystal reports which I connect to sql Sprocs using OLEDB for SQL SERVER. This works well once everything is connected but...

Problem:
If I want to change the database location to a new server it can take a couple of hours re-connecting each crystal report in my project to the new server with OLEDB in Field explorer. It is a MAJOR headache with the reports with subreports and passed params. This NEVER seems to work well.

I know there must be an easier way to connect Crystal Reports to a datasource in order to achieve a more "seamless" transition to a new datasource (or the same stored procedure on a different server - my case).

I thought that creating a dataset in my project which harbors the correct stored procedure might be a solution. So  I created a datset , added the appropriate stored procedure and connected the new dataset as the datasource for the crystal reports.

I am having trouble getting the dataset to work.

1. Crystal Reports does not recognize the SPROC's parameters and it gives erroneous values for some of the fields.

Does anyone know what may be going on here??

Thanks!

are you dynamicaly passing the connection information to reports or at designe time?
for reports designed at Stored procedures need to pass parameters with "@" sign.

My recomendation is designing of reports from stored procedure slows the reports.

I am passing the connection at design time (if I am understanding what you mean) to the stored prcedures and yes I have noticed that the reports can be slow. It works fine other than the small performance issue.

What do you mean by passing the connection information dynamically?

Thanks!

How about using a dataste from the program and passing it to the report

Thanks for the link! I have been looking for something similar with C# examples. I don't know VB at all. For some reason this type of example seems to be VB prevelant...

Agree.  There aren't many out there.

Here are some.  Not sure if there is one that fits the bill
