Using Expression Browser with ExpressionEdit Winform Object

[PTerro]

Overview

This is an example of using the ExpressionEdit control type, for TestStand 2013, on a C# Winform developed in Visual Studio 2012.  The particular function this shows is being able to use the Expression Browser within a UI.

Description

This example shows how to run a UI that sets the context of an ExpressionEdit Winform control so that the Expression Browser button on the ExpressionEdit control is enabled.  The base code for this is:

public ExpressionEdit(SequenceContext currentContext)

        {

            InitializeComponent();

            context = currentContext;

            axExpressionEdit1.Context = currentContext.AsPropertyObject();

            bool shouldAbort = false;

  int modalId = currentContext.Engine.NotifyStartOfModalDialogEx(currentContext, out shouldAbort);

            if (!shouldAbort)

            {

                this.ShowDialog();

            }

            currentContext.Engine.NotifyEndOfModalDialog(modalId);

        }

Steps to Implement or Execute Code

1. Unzip ExpressionEditDotNET.zip
2. Open 'Expression Test.seq' and run the sequence.  NOTE:  If the assembly is not loaded in the 'Expression Test Sample - dotNET' step then load the 'ExpressionEditDotNET.dll' from the relative path "\ExpressionEditDotNET\ExpressionEditDotNET\bin\Debug".
