I suggest you first try events without the timer and stream reading etc. Just instantiate a subform from the main form, click a button on the subform and make it raise the displayMessage that you'll catch and display in a simple textbox on the main form. Once you're discovered the instricacies of events you can then try it with timers, streats etc.
