Use NoRows In VB .Net 2005 Console Application

I have a VB .Net console application that invokes a report via a web service call. It then renders the report into Excel and emails it to the appropriate party.

I would like to suppress the email event if the dataset is empty. So the question is, can one access the NoRows property or equivalent in this environment?

I am able to get some information from the following code:

rs.ExecutionHeaderValue = execHeader
execInfo = rs.LoadReport(reportPath, historyID)
result = rs.Render(format, devInfo, extension, _
encoding, mimeType, warnings, streamIDs)
execInfo = rs.GetExecutionInfo()


The result and execInfo do not seem to deliver back the row count. Is this information available at all? If not, I may have to do an ADO call to the query to get it. Running the query twice is a pretty inefficient solution.
