A lot of people are looking for the PPC dial-up surfing program on the Internet. I will share my own code with you.

Check whether the network has been disconnected and re-connected in this program. You can change it based on your own situation. To share everything, I hope everyone will continue to develop this spirit, in the smart device project of wm5.0 and wm6.0 Based on MFC, the test passes the CDMA network
