Can anyone tell me what this message means? Compiling... InitTerm.cpp Linking... InitTerm.obj : error LNK2001: unresolved external symbol "public: void __thiscall Game::SortOpp(struct GAMEMSG_GENERIC *)" (?SortOpp@Game@@QAEXPAUGAMEMSG_GENERIC@@@Z) Debug/Creations.exe : fatal error LNK1120: 1 unresolved externals Error executing link.exe. I am playing around with my DP message handler. When a specific message comes in, I am trying to have my message handler pass the data it has gotten to a function in another class, using a pointer to that class. GAMEMSG_GENERIC is a struct type in which the information the Messagehandler has is passed. Thanks for any help.

Thanks HairyBudda.

I actually just found out the problem, (you are right of course, I had forgotten to add a bit to my class definitions) and was coming to delete the post, only to find it already had a reply. Man you were quick with that answer .
