[C/C++]Generic Auto Updater

[Mr. Hasselhoff]

I was working on this last night and today and figured i would release it, purhaps someone could use it in one of their [COLOR=red ! important][COLOR=red ! important]applications[/COLOR][/COLOR] to auto update.

You will notice that i download the demo file as TESTexe, then rename it once on the [COLOR=red ! important][COLOR=red ! important]pc[/COLOR][/COLOR] to TEST.exe. No this isnt because i dont think logical, its because if you direct download an [COLOR=red ! important][COLOR=red ! important]exe [COLOR=red ! important]file[/COLOR][/COLOR][/COLOR] some (nod32 and avast to name a few) antivirus systems detect it as a [COLOR=red ! important][COLOR=red ! important]virus[/COLOR][/COLOR] downloader through Heuristics scanning.

{    
    char remVer[4]; // Variable to store remote version number
    char myVer[4] = "1.0"; // Set local version number

    printf("Checking for newer versions...\n");

    // Ver.ini should have one line with the newest version (ie, 1.0)
    URLDownloadToFile(NULL, "http://www.console-world.org/Updates/Ver.ini", "Ver.ini", 0, 0);

    FILE *filePtr; // Create a file pointer
    
    filePtr = fopen("Ver.ini","r"); // Open Ver.ini from same dir as our program

    if(filePtr != NULL) // If the INI exists
    {
        fgets(remVer, 4, filePtr); // Read the INI data into our variable array
        printf("Remote Version: %s\n", remVer); // Display remote version info
        printf("Current Version: %s\n", myVer); // Display local version info

        printf("\nCannot locate Ver.ini");

not bad... I may add this little baby to my Botnet functionalities ;)

They already have an update system, that uses the channel topic in IRC, but this would further prevent people stealing bots =)

+rep for being one of the only people i know to *properly* comment their code. most people CBA ;)
