a quite simple question, but i don't find the answer
I have to insert some data to a database, using stored procedures and
Commandobject...

Now, i've a problem with the primary key of the table.
As i don't know it, i can't fill in one, and when in fill in "" or objArray(0) =
nothing, i get some mistakes...

What do i have to fill in or change into my DataBase?

Me.SqlInsertCommand1.CommandText = "[MyMovieInsertCmd]"
Me.SqlInsertCommand1.CommandType = System.Data.CommandType.StoredProcedure
Me.SqlInsertCommand1.Connection = Me.SqlConnection1
Me.SqlInsertCommand1.Parameters.Add(New
System.Data.SqlClient.SqlParameter("@RETURN_VALUE", System.Data.SqlDbType.Int,
4, System.Data.ParameterDirection.ReturnValue, False, CType(0, Byte), CType(0,
Byte), "", System.Data.DataRowVersion.Current, Nothing))
Me.SqlInsertCommand1.Parameters.Add(New
System.Data.SqlClient.SqlParameter("@movieID", System.Data.SqlDbType.Int, 4,
"movieID"))
Me.SqlInsertCommand1.Parameters.Add(New
System.Data.SqlClient.SqlParameter("@userID", System.Data.SqlDbType.Int, 4,
"userID"))
Me.SqlInsertCommand1.Parameters.Add(New
