The SqlParameter with ParameterName 'xxxxx' is already contained by another SqlParameterCollection.
I'am trying to create an dataset in which data of the different connectionpoints are separated into different tables. Herefor i'm using an stored procedure.
Below you'll find part of the main function and the full function which will execute the stored procedure.
kind regards
main function
Dim Parameters As SqlParameter() = { _
New SqlParameter("@.ConnectionPointID", SqlDbType.NVarChar, 255)}
For x = 0 To myds.Tables("ConnectionPoints").Rows.Count - 1
connectionpointID = myds.Tables("connectionpoints").Rows(x).Item("Eancode")
Parameters(0).Value = connectionpointID
mydb.doStoredProcedure("SP_EDS_Dyomes_XML", Parameters,connectionpointID.ToString, myds)
Next
Public Overloads Function doStoredProcedure( _
ByRef Mycommand As SqlCommand, _
ByRef myds As DataSet, _
ByVal Table As String)
Dim myda As New SqlDataAdapter
Mycommand.CommandTimeout = 180
If Mycommand.Connection Is Nothing Then
Dim mydb As New Database
Mycommand.Connection = mydb.generateconnection
End If
If Mycommand.Connection.State = ConnectionState.Closed Then
Mycommand.Connection.Open()
End If
CheckParameters(Mycommand)
myda.SelectCommand = Mycommand
Try
myda.Fill(myds, Table)
Catch ex As Exception
Debug.Write(ex.Message)
End Try
myda.Dispose()
Mycommand.Dispose()
End FunctionMycommand.Dispose() will release the parameter you created, and make Parameters(0) nothing|||thanx|||No problem. Hope it works for you.
