      • Anyone know any good books that teach MMC 3.0 development in C# I understand the basics, and can make simple snap-ins, but I wouldn't mind a book (or online resource) that really dives into it and shows the majority of the cool things that can be done (as opposed to me using trial-and-error to try to discover it).

The sales data has an implied decimal place, thus 5599 is really 55.99 What we have now is a function that will modify a string to go from implicit decimal to explicit but it remains a string. Later on in the process, they convert the string to a decimal value. That just offends my sensibili
