The amount of help you get is directly proportional to the amount of information you supply. For all we know, your "5-wire resistive touch control" is not "plugged in".

For WPF:

0) Add a reference to UIAutomationProvider

1) Include these usings:

C#

using System.Windows.Automation.Peers; 
using System.Windows.Automation.Provider;

3) put this code in the appropriate place:

C#

ButtonAutomationPeer peer = new ButtonAutomationPeer(forwardButton);
IInvokeProvider invokeProv = peer.GetPattern(PatternInterface.Invoke) as IInvokeProvider;
invokeProv.Invoke();

or if you want the code on a single line:

C#

((IInvokeProvider) (new ButtonAutomationPeer(someButton).GetPattern(PatternInterface.Invoke)).Invoke();
