Syntax

'Declaration
Public ReadOnly Property ReadWriteVariables As IDTSVariables90

public IDTSVariables90 ReadWriteVariables { get; }

public:
property IDTSVariables90^ ReadWriteVariables {
    IDTSVariables90^ get ();
}

/** @property */
public IDTSVariables90 get_ReadWriteVariables ()

public function get ReadWriteVariables () : IDTSVariables90

Property Value

An IDTSVariables90 that contains the collection of ReadWriteVariables.

Important

The collection of ReadWriteVariables is only available in the PostExecute method.

Remarks

The Script component developer makes variables available to the Script component for read/write access by listing them in the ReadWriteVariables field in the Script Transformation Component Editor.

The Script component developer does not use the ScriptComponent class directly, but indirectly, by coding the methods and properties of the ScriptMain class, which inherits from ScriptComponent through the UserComponent class.

The developer does not have to use the ReadWriteVariables property, because the ScriptMain class provides the Variables property for convenient access to both read-only and read/write variables through a single property. The Variables property is a property of the autogenerated UserComponent base class, not of the ScriptComponent class.

Example

The following code sample demonstrates how the Script component developer might use the ReadOnlyVariables and ReadWriteVariables properties.

  Dim localInteger As Integer
  Dim localString As String

  If Me.ReadOnlyVariables.Contains("MyIntegerVariable") Then
    localInteger = CType(Me.ReadOnlyVariables("MyIntegerVariable").Value, Integer)
  End If

  If Me.ReadWriteVariables.Contains("MyStringVariable") Then
    Me.ReadWriteVariables("MyStringVariable").Value = localString
  End If
