Custom actions created with script extensions can generate code that assigns values to variables or object properties. To generate an assignment statement, do the following:

Create an AssignSyntax object using the Syntax.CreateAssign method.
Use the Left and Right properties of the created AssignSyntax object to specify the expressions to be placed on the corresponding sides of the assignment operator (=). For information on how to generate variable and object property expressions, see Generating Variable Expressions and Generating Object Property Expressions.
If Right specifies an expression that results in an object reference, set the IsObject property to True. This is needed to generate a valid assignment statement in VBScript.

After you have configured the AssignSyntax object, you can pass it to the Syntax.GenerateSource method to get the actual script code of the assingment statement.

The following example demonstrates how you can generate code that assigns the value True to the MyVar variable:

JScript

VBScript

Copy Code

JScript

function ShowAssignmentStatement ()
{
  var oVarName = Syntax.CreateInvoke();
  oVarName.InvokeName = "MyVar";
  oVarName.IsProperty = true;

  var oAssignment = Syntax.CreateAssign();
  oAssignment.Left = oVarName;
  oAssignment.Right = true;

  var strCode = Syntax.GenerateSource(oAssignment);
  aqDlg.ShowMessage(strCode);
}

VBScript

Sub ShowAssignmentStatement
  Dim oVarName, oAssignment, strCode

  Set oVarName = Syntax.CreateInvoke
  oVarName.InvokeName = "MyVar"
  oVarName.IsProperty = True

  Set oAssignment = Syntax.CreateAssign
  oAssignment.Left = oVarName
  oAssignment.Right = True

  strCode = Syntax.GenerateSource(oAssignment)
  aqDlg.ShowMessage strCode
End Sub
