A tiny c# app that operates the Open File dialog using White. Useful if you're testing a WPF app with bewildr (http://www.bewildr.info) but the app you're testing uses the old Win32 dialog boxes. The compiled exe takes one arg; the value you want typed in

Program.cs

/*
Create a console app, add references to the various white libraries and use the following as a template for operating the Open Dialog window
Get the white binaries from here: http://white.codeplex.com/
*/

using System.Collections.Generic;
using System.Linq;
using System.Windows.Automation;
using White.Core;
using White.Core.UIItems;
using White.Core.UIItems.Finders;
using White.Core.UIItems.WindowItems;

namespace OpenFile
{
    class Program
    {
        static void Main(string[] args)
        {
            Application myApp = Application.Attach("YOUR_APP_PROCESS_NAME_HERE");
            List<Window> myWindows = myApp.GetWindows();
            Window openDialog = myWindows.Where(n => n.Name == "Open").First();

            TextBox textField = openDialog.Get<TextBox>(SearchCriteria.ByControlType(ControlType.Edit).AndByText("File name:"));
            textField.Text = args.First();

            Button openButton = openDialog.Get<Button>(SearchCriteria.ByControlType(ControlType.Button).AndByText("Open"));
            openButton.Click();
        }
    }
}

childWindow.Get(SearchCriteria.ByAutomationId("1148")).Select(1);
var OpenButton = childWindow.Get(SearchCriteria.ByClassName("Button").AndAutomationId("1"));
OpenButton.DoubleClick();

works for me.
