I need a simple code to act as VPN client, there are 2 kinds of VPN account:
A:) L2TP, but it need use preshared key for authentication, (Not normal but support by Windows);
B:) SSTP, for Windows 7/8 user;
You can find related information at msdn:
L2tpPsk is the key. Please pay attation, it's not easy L2TP,PPTP client code, and you need know Win32 API to complete it.
When you accept this project, I'll send some VPN accounts for debug/test;
All the function for this program is:
* Dial VPN, detect if there is any errors;
* Detect if is online;
* Discount when requested;
I need full source code; And if we are happy for each others, there is still other projects for you;
