VC post form -- logon verification Sina mail

1. Local Environment:

Windows XP SP3 and ADSL

 

2. Development tools:

Wildpackets omnipeek v5.1.4

Visual c ++ 6.0

Ie6.0

Flexedit v2.3.1871

 

If you feel that the omnipeek file is too large to download friends, you can use the open source simple packet capture analysis tool, first log on to codeproject, then click here to download or mail me for source code (ningyusky@tom.com or koma0769@vip.qq.com)

 

Note: If you have not logged on to the codeproject, you cannot download it. You can modify the source code of the tool and record all the data of get and post operations in a file, to view the analysis .....

 

This is what I do, because my hardware configuration is not very "mainstream", so every time omnipeek starts and creates a project, the computer is about to crash .....

 

3. program running effect:

 

 

4. Source Code Description:

 

Although there are more than one hundred lines of code in such a short time, I debugged it for more than three hours to solve each of the errors that may exist here, I hope to discuss with you ......
