>>Hey gang,
>>Here is my situation - I am attempting to build a generic Crystal Reports class where the end-user provides a path to the .rpt file, a path to an .xml file, and other options on how to export the report. A requirement is for the .xml file to have an external schema.
>>
>>In my class, I am importing the .xml into an un-typed DataSet using the DataSet.ReadXML method and passing that into the report. The problem is that all of my fields are converted to strings somehow and it my report I get errors when I try to multiply two numeric values in a formula.

>>How can I make this work so the types of my values are preserved?

Yes, I looked at those but I think they only read an inline schema. I found a ReadXMLSchema method where I can define the actual .xsd file and then the DataSet becomes strongly typed. However I can't seem to successfully read the data in using ReadXML after I do this.
