Answer 1

Is something like this what you wanted?

// begin execution asynchronously
IAsyncResult result = myObject.BeginInvoke("data.dat", null, null);

// wait for it to complete
while (result.IsCompleted == false) {
   // do some work
   Thread.Sleep(10);
   }

// get the return value
int returnValue = myObject.EndInvoke(result);
