I understand that some 3rd party apps provide much greater functionality as related to parameters and passing data commands though. There are methods in V8.5 and V9 to accomplish something similar. It does involve quite a bit of code, though.
DataLink Viewer might be adequate, but if the default is the web or another Crystal viewer, the overcost cost of purchasing licenses for the DataLink Viewer might not be an option.
Without knowing more about the VB app used and their familiarity with interacting with the V7 API, we are just guessing. Rod Oatis
