pass parameter in windows form (choose one or many from thousands)

[Helen]

Hi, I have a crystal report version 9 in vb .net 2002, am calling the parameters at runtime and not using the crystal parameter box. I get results by hard coding the discrete values

But, I really need to call all results for the parameter in a separate windows form in a combo/drop-down text box, whatever, before loading the viewer. There could be thousands of results, so must handle this way. The user would choose one or several, then once chosen, click ok to load the report

Does anyone have any sample code

Much appreciated! Thanks, Helen
