In the example program on TG2 page 108, the line
CreateGUIDialogBox(10,10,40,30,””,”Blue Wins!”,”OK|Yes|No”)
is incorrect. I double and triple checked the code for CreateGUIDialogBox to make sure I copied everything correctly, and it does indeed take eight parameters, not seven. I fixed it by doing this:
CreateGUIDialogBox(10,10,40,30,"","Blue Wins!","","OK|Yes|No")
You can also do this, as mentioned in the exercise:
CreateGUIDialogBox(10,10,40,30,"bluewins.png","Blue Wins!","blankbut.png","OK|Yes|No")
Congrats on 1000+ pages and this is the first mistake I've found that didn't turn out to be my own error.
