I have been trying to retreive information from database A and pass it on to database B

Dim mr As DataRow = dsProben.Tables("T_Proben").NewRow

Dim dr1 As DataRow = dsProzessmodule.Tables("T_Prozessmodule").Rows.Find(selectedKey)

mr("pProzessmodulGUID") = dr1("ProzessmodulGUID")

though this works in other forms it doesnt seem to work here. I get the error NUll Reference Exception was Unhandled

could someone help me this.

thanks
