Win forms, register all clicks?

Question

Is there a way to register all clicks in a Win Forms application? I would like to capture clicks and record the action and name of the control that caused it.

Is it possible?

Thanks in advance.

UPDATE: I am looking for a solution for a wide range of applications, is there no way to add a listener to the Windows event queue (or what is ever called)?

You can do this by specifying the main form of your application on the IMessageFilter interface. You can display received Window messages and search for clicks. For instance:

  public partial class Form1 : Form, IMessageFilter {
    public Form1() {
      InitializeComponent();
      Application.AddMessageFilter(this);
      this.FormClosed += (o, e) => Application.RemoveMessageFilter(this);
    }

    public bool PreFilterMessage(ref Message m) {
      if (m.Msg == 0x201 || m.Msg == 0x203) {  // Trap left click + double-click
        string name = "Unknown";
        Control ctl = Control.FromHandle(m.HWnd);
        if (ctl != null) name = ctl.Name;
        Point pos = new Point(m.LParam.ToInt32());
        Console.WriteLine("Click {0} at {1}", name, pos);
      }
      return false;
    }
  }

Please note that this logs all clicks in any window of your application.

MouseEventArgs :

    private  void Form_MouseDown(object sender, System.WinForms.MouseEventArgs e) 
{ 
switch (e.Button) 
{ 
    case MouseButtons.Left: 
    MessageBox.Show(this,"Left Button Click"); 
    break; 
    case MouseButtons.Right: 
    MessageBox.Show(this,"Right Button Click" ); 
    break; 
    case MouseButtons.Middle: 
    break; 
    default: 
    break; 
} 

EventLog.WriteEntry("source", e.X.ToString() + " " + e.Y.ToString()); //or your own Log function

}

The NunitForms test project has a recorder application that monitors this and many other events. The code is very smart and worth a good look. This is a ThoughtWorks project.

What a roll royce solution though! ...

Try recursively go through a collection of form controls and a subscibe to a type-based event.

PK :-)
