Forgotten World

[thisisjustatest80]

OK so this may be lame, but...

I found the data for my character, but I cannot alter that data in any way. I even tried setting up a break and tracing back from when the data was written to, and I can't figgure it out. So instead of altering data, I wanted to try a different route: monitor the data until there's a result I want (unlike EQ, starting stats are random, and you can keep rerolling 'till you're happy).

However, I have no idea how to write a program to monitor another program's data. I've only ever written self-contained programs. So if possible, I was wondering if there was an easy way to:

1) Send a keystroke to another process
2) If the result in memory isn't the desired result, repeat

This seems like it's easy, I just don't know how to send a keystroke to another process or how to check another process' memory.

Thanks in advance.

I figured it out, though I am no windows programmer. It's running rather slowly I think in part because there's no event handler, so I'm pretty sure my process is hoggin the processor time. If anyone has suggestions, they'd be appreciated.

Any suggestions on making it interact better?
