Re: Help calculate checksum (newbie)

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Yes it does, but I can't figure out how to calculate it using vb or c#.
Can you help me?

thanks in advance,

I have a situation where need to calculate a checksum of some byte array.
Here's the sample output from server:
2008-09-30 11:35:00 `SC`00541.00TJ123456PPC 00000000DLGLGN 00000001TXBEG Login:user=mmlos, pswd=osmp

The checksum is 9afb81c7

I cannot figure out where this checksum come from, can anyone post a sample in vb.net or C#?
See the packet description at http://www.epay.tj/img/MML-Packets.jpg

Doesn't the packet description contain information on how to calculate the checksum (4.)?
