  Hi Guys,

  I am very much new SQL and VB, I am trying to add header, details and footer to flat files using VB. Below is the sample script I got it from one of the forum. But I need to replace all the variables with my requirement. Basically, this can be accomplished by creating the header or footer in a separate task, and then prefixing or appending it to the data. . The final output file, which includes the header, data, and footer rows.

  Header Field Names: RecordTypeCode, RecordFormatVersionNo,DataDateFileIdentificationCode

  Details from source table: LoanID, SourceID, Borrower, SetttlementDate, Repay

  Footer: RecordTypeCode, RecordFormatVersionNo,DataDateFileIdentificationCode,DetailRecordCount (This has to be count of records in detail table), controlTotal1

  SSIS package : DataFlow 1 (Row Count From source to Flat File) --> DataFlow 2 ( Append Trailer through VB Script and place same flat file ) --> Script Component ( Add heater).

  I have declared a variable exactly like this in Dataflow

  First Data Flow :(eg. ETLLoanTableàRowCount (I have declared variable here as RecordCount) à FlatFileDestination).

  Second Data Flow : I am trying to append footer using below script. Below highlighted code need to change according my requirements, please can anyone help me with this.

  ' Microsoft SQL Server Integration Services user script component

  ' This is your new script component in Microsoft Visual Basic .NET

  ' ScriptMain is the entrypoint class for script components

  Imports System

  Imports Microsoft.SqlServer.Dts.Runtime.Wrapper

  Public Class ScriptMain

  Inherits UserComponent

  Public Overrides Sub CreateNewOutputRows()

  Dim recordCount As Integer

  Dim vars As IDTSVariables100

  'Get the record count

  Me.VariableDispenser.LockOneForRead("RecordCount", vars)

  recordCount = CType(vars("RecordCount").Value, Integer)

  vars.Unlock()

  'Output one row with record count

  Output0Buffer.AddRow()

  Output0Buffer.FooterRow = String.Format("Footer Row Count: {0}", recordCount)

  Output0Buffer.SetEndOfRowset()

  End Sub

  finalFile = CType(vars("FinalFile").Value, String)

  vars.Unlock()

  fileContents.AppendLine(String.Format("Header Row Count 1: {0}", recordCount))

  fileContents.Append(File.ReadAllText(Dts.Connections("Destination").ConnectionString))

  File.WriteAllText(finalFile, fileContents.ToString())

  Here is the link to which I followed : http://agilebi.com/cs/blogs/jwelch/archive/2008/02/08/adding-headers-and-footers-to-flat-files.aspx

  I am changing Output0Buffer.FooterRow = String.Format("Footer Row Count: {0}", recordCount) to Output0Buffer.footer= String.Format("Footer Row Count: {0}", recordCount) however I am getting error mess: footer is not a member of script component

  Can any please tell me where to change or check member in script component.

  Many thanks,
