VB.Net coding re:Crystal Reports passing back info

Question

I am trying to return the row count or a variable / running total from the Crystal Report If zero, then, I don't want to save as PDF and then E-mail. So far, all I could find reference to is returning the page count, the code for a formula, SQL, etc, but can't seem to find anything in regards to returning the "value" of a formula or a running total. Is this possible ? What other web resources could lead me in the right direction ?
