You should then have enough information to write your own code based on what ever book you are following or the information provided by your tutor. Currency conversion is a fairly easy problem to solve. You have a source currency and a destination currency and a conversion factor. This is usually expressed in the format of one unit in the source currency is equal to some units of the destination currency. For example. £1.00 == €1.46 So, to get from Sterling to Euros (left to right) you multiply the value by 1.46. To get from Euros to Sterling (right to left) you divide by 1.46. How about if it is expressed the other way around. €1.00 == £0.68 The calculation is the same (left to right / source to destination) you multiply. To go the other way (right to left / destination to source) you divide. Does this help?

There's nothing to this. The most complicated part is getting the current exchange rate for the currencies involved. I don't know of a public source myself, but if you get this data, the rest is easy: TargetCurrency = SourceCurrency * ExchangeRate.

Hmm, Depend what information did you get? for example you want to know for 50 USA is how much on money on RMB Frist you need to know 1.00 USD = 8.50 RMB then using the following equation A = 1.00 USD_ B = 8.50 RMB_ C = 50.00 USD_ X = ? RMB_ A (USD_) = B (RMB_) --> eq.(1) C (USD_) = X (RMB_) --> eq.(2) X = (B/A) * C You can create a Function to accomplish that. Hope it will help. If I am wrong please correct me.:doh:
