Dynamically change an image in a Crystal Report at runtime

One approach I've done to solve this issue in the past is to create my own "parameter entry" screen for the user to specify their custom values. Once submitted, the process runs its own custom query and injects the result set into the Crystal Report. The report then simply serves as a presentation mechanism for the data.

What makes this nice is that you can configure the Crystal Report to use the XSD source as its data model, which serves as an empty skeleton of what the data will look like. Then in your code behind for your form you do something as simple as this:

Dim crResults As New ReportDocument
Dim dtReportData As New DataTable

crResults.Load("PathToReport", OpenReportMethod.OpenReportByTempCopy)
dtReportData = RunStoredProcedure(ReportInfo.ProcedureName, ReportInfo.Parameters)
crResults.SetDataSource(dtReportData)

Note: The RunStoredProcedure is a custom function I setup to call a stored procedure and pass in a HashTable of parameters to bind, but you can roll this any way you need to to get the DataTable storing your results.

I couldn't find a straight forward way of doing this so I wrote a blog on it
