vs 2008 c# called stored procedure wait

How would I construct a VS 2008 C# project that calls a stored procedure to present to the user a MessageBox that would blink as the stored procedure is running and then present one final message box when the stored procedure is complete. Right now the sp takes about 4 minutes to run. I want to give the user some visual cue that it is running and then a completion message. Right now, when I call the sp, the message box immediately appears because it is not waiting for anything from SQL to tell my project that the sp is complete. How do I get my project to wait for completion?

Use Asynchronous delegates with call back on completion. Here is an example:-

YourDelegateObject.BeginInvoke("data.dat", new AsyncCallback(CallbackMethod), flusher);

void CallbackMethod(IAsyncResult result) {
   // get the delegate that was used to call that
   // method
   your code goes here
}
