String Compression/Server--->Client
Author
Hi,
Who can help me with this?
1.I want to compress a string server-side in VB.NET or VC.NET
2. Then I want to send the string to the client(browser)
3. Then I want to uncompress the compressed string with java-script or vbscript.
How can I accomplish this?
Any help would be great. Thanks!
I would try a common compression technique like huffman coding. Unless your strings are long though you may end up sending more than you would have originally.
Also, try doing a google search for string compression.

I did. I didn't manage to solve my problem. Now I'm asking the real die hard coding pro's;-)

Hi!
May be I didn''t understand good your problem, but really I can see no TOO much difficulties
char str[512];
char compressedStr[512];
char *buffer = str;
int totalSend = 0;
int sendBytes = 0;
...
compressedStr = CompressString( str, compressedStr );
...
while( totalSend < wantToSend ){
if( ( sendBytes = send( socketFd, buffer, wantToSend - totalSend, 0 ) ) < 0 ){
exit(1);
}
totalSend+= sendBytes;
buffer+= sendBytes;
} // END WHILE
In fact, there is NO difference ( sending plain text ), is string compressed or not!
P.S. This code is not tested, I wrote it directly in browser

Try feeding "huffman" in the MSDN search. The first mach I got (October 2001 version) is an article called "Data Compression and Visual Basic". It comes with full code, and lots of explanations.
