Hello

Those who have used WatiN likely also used DialogHandlers.

Well can someone teach me how can i assign a DialogHandl

Answer 1

Create class:

public class OKDialogHandler : BaseDialogHandler
{
    public override bool HandleDialog(Window window)
    {
        var button = GetOKButton(window);
        if (button != null)
        {
            button.Click();
            return true;
        }
        else
        {
            return false;
        }
    }

    public override bool CanHandleDialog(Window window)
    {
        return GetOKButton(window) != null;
    }

    private WinButton GetOKButton(Window window)
    {
        var windowButton = new WindowsEnumerator().GetChildWindows(window.Hwnd, w => w.ClassName == "Button" && new WinButton(w.Hwnd).Title == "OK").FirstOrDefault();
        if (windowButton == null)
            return null;
        else
            return new WinButton(windowButton.Hwnd);
    }
}

After creating instance of IE, attach dialog handler to it:

ie.AddDialogHandler(new OKDialogHandler());

This dialog handler will handle all windows, that contains a button with "OK" caption, by clicking on that button.
