Hello, I'am working with a script component in SSIS 2005, i have a variable which i use in my package, i want to call this variable in my script to increment it as many times of number of entry lines in my dataset. I do this script Public Class ScriptMain Inherits UserComponent Dim Counter As Integer Public Sub New() ' 'Initialise the variable Counter = Me.Variables.vNNN006 ' 'MsgBox(Counter) 'End Sub Public Overrides Sub Entre0_ProcessInputRow(ByVal Row As Entre0Buffer) ' ' Add your code here ' Counter = Me.Variables.vNNN006 Counter += 1 Row.EDOCS = Counter 'MsgBox.Show(Counter.ToString()) MsgBox(Counter) End Sub End class But when i execute i have this exception Erreur de validation. Tche de flux de donnes*: Composant Script [296]*: System.Reflection.TargetInvocationException: Une exception a t leve par la cible d'un appel. ---> Microsoft.SqlServer.Dts.Pipeline.ReadOnlyVariablesNotAvailableException: La collection de variables verrouille pour l'accs en lecture n'est pas disponible ce stade. Microsoft.SqlServer.Dts.Pipeline.ScriptComponent.get_ReadOnlyVariables()... I don't understand this, i don't have error in my script Can someone help me please

It seems the variables aren't available. Did you configure them in the properties of the script component? This blog lists all the steps to work with variables in a script component: http://microsoft-ssis.blogspot.be/2011/01/how-to-use-variables-in-script.htmlMCTS, MCITP - Please mark posts as answered where appropriate.

For Accessing variable inside script component for example create some variable var1 for package level then this variable inside script component can be called using private int var_scrpt= 0; if (ReadOnlyVariables.Contains("var1 ") == true) { var_scrpt= Convert.ToInt32(ReadOnlyVariables["var1 "].Value.ToString()); }karteek_miryala

Did you set the variable as ReadWrite for your script component. Check his example: http://www.programmersedge.com/?p=1350
