I am making my first ever win32 app, a tic tac toe game, using C++, and thus far i have been able to make a 3 by 3 grid of buttons that when clicked will show X's and O's based on who's turn it is. What i am having trouble doing is figuring out how to clear all the X's and O's once the game is over (I haven't got around to making my program determine if there is a winner or not yet, that will come later).
So i have made a "New Game" button, but i don't know how to get everything to clear when it is clicked... Any help?

I'm sorry my organization is probably terrible.... But the code compiles and does what i have explained up until now. Also i should add that i do have header files that i am not including that define the variables that you probably see undefined in this code. Thanks for any help you can give me on how to "reset" everything using the "New Game" button
Reset playerobject and all your click globals back to zero, and set the text of each button back to nothing, e.g. SetDlgItemText(hWnd, IDM_LOC1, "");.
