[slackman]

if((update = fopen("http://www.???.com/update/version_update.txt", "r")) == NULL)
{
printf("Error Opening File.\n");
exit(1);
}

while( fgets(line_version, sizeof(line_version), update) != NULL )
{
printf("%s", line_version);
}

fclose(update);

fopen() only works on local files.

Doing network things is a whole different universe that the basic C library knows nothing about. If you want to open remote files, you either need to write it yourself (using sockets and low-level network calls) or find a library that somebody else has written that makes it simple to work with remote files over HTTP.
