Custom actions created with script extensions can generate script code that uses variables. After creating a variable declaration, you can generate code that uses this variable. To generate an expression containing a variable name, follow these steps:

Call the Syntax.CreateInvoke method to create a new InvokeSyntax object.
Specify the variable name in the InvokeName property of the created InvokeSyntax object.
Set the object’s IsProperty property to True.

The resulting InvokeSyntax object can be used to create more complex expressions and statements, for example, assignment statements (see Generating Assignment Statements).

The following example demonstrates how to generate an expression that refers to the MyVar variable:

JScript

VBScript

Copy Code

JScript

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

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

VBScript

Sub ShowPropertyStatement
    Dim oVarName, strCode

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

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