I've just started using of VB 2003 standard edition. I compiled Bhruhic 3.13 BTS patch source code and it came out working normally (but larger in size). However, I'm rapidly making very little progress with my "own" code. I've been trying to graft the "UpgradeCost" building tag from the Warlords CCCP source code onto Bhruhics BTS code. What I find is that some identifiers are apparently undeclared. Don't you declare them in the header (.h) files? I can't see where I haven't done the declaration. Any help for this poor, simple beginner would be greatly appreciated.
