c++ file hooking for poker site

I would like a C++ program that can hook into a poker client and convert any "euro" and "pound" symbols into "$" symbols? (conversion is only required for files written to the hard disk not inside the actual poker client) ## Deliverables The site is: [login to view URL] You will need to sign up and create a play money account. ? Once you start playing at a table, hand histories will be written to the hard disk. ? Although this should be sufficient to write the majority of the hooking code, unfortunately play money tables do not actually have euro or pound denominated tables. ? I'm happy to send across a sample hand history to assist in the coding. ? Alternatively if you wish to create a real money account for testing feel free to add a modest (<$25USD) amount to your price to cover the costs. The software should in real time convert euro (?'?) and pound (£) symbols into dollar ($) symbols for hand history files written to the hard disk. ? It should have a reasonably small footprint and should be capable of running for at least 24hrs without any noticeable degradation in system performance. The way I imagine the software running is: . ? I open the poker client . ? I run the executable which installs a hook and monitors written files in real time . ? Does not need GUI can be command line based . ? The program accepts a combination key e.g. Ctrl-Q which then removes the hook and terminates gracefully
