I have code that I've used in 3.5 and works. 4.0 for some reason doesn't work.

I placed the information below.

Thx
Dim TotNumRows As New SqlParameter("@TotNumRows", SqlDbType.Int)
        TotNumRows.Value = Nothing
        TotNumRows.Direction = ParameterDirection.Output
        DataAdapter.SelectCommand.Parameters.Add(TotNumRows)
        DataAdapter.SelectCommand.Parameters("@TotNumRows").Value = Nothing


I will call a public Sub from here and it bombs with the Input String was not in correct format.
avigation(Convert.ToInt32(TotNumRows.Value.ToString()))

Here is the sub I call

  Public Sub Navigation(ByVal totalRows As Integer)
  End Sub

you need tochange nothing to integer value like 0

TotNumRows.Value = Nothing

must be

TotNumRows.Value = 0

Dim TotNumRows As New SqlParameter("@TotNumRows", SqlDbType.Int)
        TotNumRows.Value = 0
        TotNumRows.Direction = ParameterDirection.Output
        DataAdapter.SelectCommand.Parameters.Add(TotNumRows)
        DataAdapter.SelectCommand.Parameters("@TotNumRows").Value = 0
0

You assign Nothing as a value to the parameter. Is this an error or is this because you want to pass Null?

I can't use TotNumRows = 0, Because @TotNumRows is an Output Parameter from SQL Server. It does a row count of the total number of records I'll be using. It sends it back to .Net.

@JamesBurger & pratima_mcs:

I resolved this on my own. My own stupidity.  I didn't set my row count in the Procedure. This fixed it.
Resolution:
SET @TotNumRows = @@ROWCOUNT
