hi all..

i am very confused right now, i cannot connect a vb.net application to crystal report ONLY IF it has parameters. The data can be displayed if it has no parameter. But if it has parameters, the application always shows message box that tell me logon failed, prompting me for user name and password. The application I run is VB.net How To - Crystal Reports Print Preview from 101 VB.Net samples

Can anyone help me please?
