Sarah,
 
How are you asssigning the dataset to the report?  You need to be sure to set the DataSource of the report to the DataSet in your application prior to viewing the report.  This way it will correctly point to the instance of the DataSet that has data in it.
 
I work with the ReportDocument object model instead of the Crystal Viewer object model.  Here's a sample of what I do in C#:
myRpt = new MyCrystalReport();
rpt.SetDataSource(myDataSet);
viewer.ReportSource = rpt;

Hi Mitch
 
I have a connection string, it is defined as follows:
 
Data Source=MERLOT\SQLEXPRESS;Initial Catalog=sarah;Integrated Security=True
 
MERLOT is my host, where I am running SQL Server.  'sarah' is the name of my test database.
 
I have been looking into the matter of connection strings and it seems to be an arcane science, not for the uninitiated or fainthearted.
 
I am just wondering, if the Microsoft Reporting is working OK then presumably my connection string is OK, as I'm able to pass the data into my application that way.

Hi Sarah7
 
CR is a learning curve, I agree if you can connect and run MS Reports you are ok. Don't forget to save the CR report, after tweaking changes. Last, I had to manually change in Set Datasource Location ->
Provider: SQLOLEDB
you may want to try the other connection types.
