Data Environments

Is anybody familiar with this flaming DataEnvironment Designer in VB6, its drving me nuts!!.

I have created a Commaand of SQL Type and have Paremters setup. I have put an MSHFlexGrid on a form and set the DataSource to DataEnvironment1 and the DataMember to Command1. When I open the Form the Grid is empty, I know the command is ok as when I run in design mode it brings back records.

I have tried passing the Parameters to the command by using ;

DataEnvironment1.Commands(1).Parameters(0).Value = "Judgey"
DataEnvironemnt1.Commands(1).Execute

Can anybody help , or does anybody know where I can look on the net for instructions on how to use the DataEnvironment?
