I'm new to C#, so cut me some slack, but I'm going nuts over Ex. 1 at the end of ch. 12. Am I reading this question incorrectly or is it simply not possible to use a multi-purpose event handler in the manner described. Unfortunately, the code download that I have doesn't give the code for these exercises, just the easy ones in the chapter for which the code is already provided! ARRRRRGHHHHHHHH!!! Any help would be greatly appreciated.
