Within a sub can I determine the control that called it.

I can add a parameter to the sub so that I call it:

MySub(This, ...

But I'd rather not.

Is there some way to determine the caller within the sub?

Thanks in advance

If it's an event handler, then the first parameter "object sender" is
that control; just cast it to the appropriate type, e.g.

void button1_Click(object sender, EventArgs e)
{
Button b = (Button) sender;
}

Otherwise, no, you can't.

I was hoping StackTrace or Reflections, which I know nothing about, would
work.

Thanks.
