Use this method with Winsock. Ever had it when you need to send lots of data all at once, and you need individual structured fields for each commands? Does your field data contain special characters or binary data? Conventional methods of delimiting packets simply won’t allow you to get away with that. This code demonstrates how to use Byte Level Delimiting (as I have dubbed it, anyway), and also shows how to buffer incoming and outgoing data, so you can handle large data flawlessly. There is a word document inside the ZIP archive that explains the principle and mechanics of the idea, and also code to demonstrate it. Also uses protocol compression, if the compressed size is smaller than the decompressed size (ZLIB). Feedback greatly appreciated, thank you.

 Download code
Note: Due to the size or complexity of this submission, the author has submitted it as a .zip file to shorten your download time. Afterdownloading it, you will need a program like Winzip to decompress it.Virus note:All files are scanned once-a-day by Planet Source Code for viruses, but new viruses come
out every day, so no prevention program can catch 100% of them. For your own safety, please:
- Re-scan downloaded files using your personal virus checker before using it.
- NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.
- Scan the source code with Minnow's Project Scanner
If you don't have a virus scanner, you can get one at many places on the net
including:McAfee.com

I know of a much easier method. First off get strfun module (can be obtained at PSC I believe). Then its just 8 lines of code to extract all the parameters. It is sent like so
PARAM1*&*PARAM2*&*PARAM3*&*PARAM4*&*PARAM5

Polygon105:
What happens if your parameter contains *&*? Your data gets screwed up at the other end, thats what.
The whole point of this submission is to overcome this problem.

Nice idea, but buggy and prone to crashing on unexpected data. (I've tested it). I just submitted one of my own which is similar I guess, and doesn't support compression (yet), but it's 100% reliable. Regardless, I wish I had found your submission years ago when I first started writing client/server programs!
