Hi,
I am using Microsoft's UI Automation library for quite a while now, and I have been able to manipulate textboxes and buttons. However, I have problems with some of the controls.

I have a program that I want to automate, which have a picture box and a link label that functions like a button click. This means that if I clicked on the picture box or the link label, I will trigger an event, and be directed to another page.

I have tried using the invoke method, which buttons have, but was unsuccessful. Is there any other way to trigger the click event or something similar for a picture box or link label?
Thanks in advance.

If you don't mind straying out of the UI Automation system:

If you can locate the window-handle of the control you want to click (I believe the automation system gives access to the window-handles), you could use the windows api to send a mouse-button down, and mouse-button-up message to the controls handle.... this is much the same as actually clicking the control.

Its not the most elegant solution though.

XML

/// <summary>
/// sends a windows message to the specified window handle.
/// </summary>
/// <param name="hWnd">the window handle</param>
/// <param name="Msg">the message constant</param>
/// <param name="wParam">w parameter</param>
/// <param name="lParam">l parameter</param>
/// <returns>IntPtr Result</returns>
[DllImport("user32.dll")]
public static extern IntPtr SendMessage(IntPtr hWnd, int Msg, IntPtr wParam, IntPtr lParam);

C#

public const int WM_LBUTTONDOWN = 0x201 ;
public const int WM_LBUTTONUP = 0x202  ;
