Yes you have parameters to be passed, no you don't use them. This means that you can use the second solution. Simply call: KeyBoard_Lock(null, null);

To use my first solution do this (you can name SomeFunction() to whatever you like):

public void SomeFunction()
{
if (receivedData == "###LOCK###")
{
actHook = new UserActivityHook();
// crate an instance with global hooks
// hang on events
//actHook.OnMouseActivity+=new MouseEventHandler(MouseMoved);
actHook.KeyDown += new KeyEventHandler(MyKeyDown);
actHook.KeyPress += new KeyPressEventHandler(MyKeyPress);
actHook.KeyUp += new KeyEventHandler(MyKeyUp);
}
}

Then do this:

private void ListenToServer()
{
SomeFunction();
}

public void KeyBoard_Lock(object sender, System.EventArgs e)
{
SomeFunction();
}

So now, you call your SomeFunction() in ListenToServer(), but as you see, KeyBoard_Lock(object sender, System.EventArgs e) does the same.

AA23 is not empty. It has a IF statement, with 0 when true and 1 when false. Default is true, so it's default value is zero, not empty.
object oMissing = Type.Missing;

In my example I wanted to call the button click EventHandler in the KeyDown EventHandler, but why? I asked myself. Why should I want to call a buttonClick EventHandler in a KeyDown EventHandler, that's too confusing, because, after all, one EventHandler is for a buttonClick where the other is for the KeyDown, right? So why would I want to call a buttonClick EventHandler in my KeyDown EventHandler. Or, if you are not calling it in an other EventHandler, but in a function, why would you want to call the buttonClick EventHandler (or some other EventHandler) if you are not performing that action? So that's why I decided to put my code of the button click EventHandler in it's own function, and then have my button click EventHandler and my KeyDown EventHandler to call that function. Both are calling the same function, so both are doing the same.

Calling an EventHandler when you are not raising that event is confusing.

Already worked on that ;)
