Generating Object Property Expressions

Applies to TestComplete 15.42, last modified on August 01, 2022

Custom actions created with script extensions can generate script code that refers to object properties in order to get or set their values. To generate an expression that refers to an object’s property, follow these steps:

  • Create a new InvokeSyntax object using the Syntax.CreateInvoke method.

  • Use the ClassValue and InvokeName of the created InvokeSyntax object to specify the object that contains the property to be referred and the property name, respectively.

  • Set the IsProperty property of the InvokeSyntax object to True.

  • If the target property uses parameters, use the AddParameter method of the InvokeSyntax object to specify the parameter values to be used in the generated code.

After configuring the InvokeSyntax object, you can pass it to the Syntax.GenerateSource method to get the actual script code of the property expression.

The following example demonstrates how to generate an expression that refers to the Sys.Clipboard property:

JScript

function ShowPropertyStatement()
{
    var oPropName = Syntax.CreateInvoke();
    oPropName.ClassValue = "Sys";
    oPropName.InvokeName = "Clipboard";
    oPropName.IsProperty = true;

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

VBScript

Sub ShowPropertyStatement
    Dim oPropName, strCode

    Set oPropName = Syntax.CreateInvoke
    oPropName.ClassValue = "Sys"
    oPropName.InvokeName = "Clipboard"
    oPropName.IsProperty = True

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

The generated code is as follows:

JavaScript, JScript

Sys.Clipboard;

Python

Sys.Clipboard

VBScript

Sys.Clipboard

DelphiScript

Sys.Clipboard;

C++Script, C#Script

Sys["Clipboard"];
