Hey everyone I need some help. First a little back story. I am getting a new Pocket PC for Christmas and i thought it would be cool to have a FIRST playbook application on it so i could make autonomous “plays”. I did a little research and found out i need to learn win32 (something I have wanted to do anyway) before I could write an app for windows CE. so i found a nifty little tutorial that explained windows programming well. Then i hit a wall. I did the the tutorial on modal dialogs. Everything complied fine but no dialog box when i select the about menu under help. I’m using DevC++. Here is the code. Anyone got any Ideas? Thanks.
