Thread: Open a WebPage

Is there a way to open a web page in C?

I'm a newbie in this, im just starting... My goal is to open a link to a web page after the user enters the correct password. I can post my code so far if you ask for it, where it asks for the password and when it gets the correct one it opens up a program (iexplore.exe).

please help

ok so i didn't know how to attach or write my code here.. but I read the rules!!

Code:

#include <stdio.h>
#include <stdlib.h>

int main()
{
    char* pass;
    char* p="hello";
    int i=0;

    printf("Enter password and press ENTER.\n \n");
    do
    {
        printf("Password: ");
        scanf( "%s",  pass);

        if(strcmp ( pass, p ) == 0)
        {
            printf("Correct Password. \n \n");
            i=10;
        }
        else
        {
            if(strcmp ( pass, "hint" ) == 0)
            {
                printf("Password Hint: Form of salutation. \n \n");
            }
            else
            {
                printf("Incorrect Password. \nType 'hint' for help. \n \n");
                i++;
            }
        }

        if (i == 3)
        {
            i++;
            printf("\n---- PROGRAM TERMINATED ----\n--- PRESS ANY KEY TO END ---\n");
            getch();
        }
    }
    while (i<4);

    if (i == 10)
    {
        printf("Press ENTER to continue... \n");
        getch();
        //Open a program or file
        system ("C:\\PROGRA~1\\INTERN~1\\iexplore\.exe");
        printf("\n---- PROGRAM TERMINATED ----\n--- PRESS ANY KEY TO END ---\n");
        getch();
    }

    return 0;
}

so as you can see now, i did use the system() to call for iexplore.exe, but how do i open a specific page? i dont want it to open the homepage. i've been reading also some kind of changing the registry keys of windows so the c program would change the homepage, but that's kind of intrusive!

i don't get it... :S
like this?

this is only the end....

Code:

        //Open a program or file
        open (webpage);
        printf("\n---- PROGRAM TERMINATED ----\n--- PRESS ANY KEY TO END ---\n");
        getch();
    }

    return 0;
}

void open(char *webpage)
{
    system ("C:\\PROGRA~1\\INTERN~1\\iexplore.exe");

As laserlight pointed out concatenate the URL string to the iexplorer executable.

im sorry but i've been trying and i dont get the concatenate...
i searched and i think i got the the concatenate right.. but is not working like that, it just ends. this is what i got:

Code:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

char* internet="C:\\PROGRA~1\\INTERN~1\\iexplore.exe";
char* url="www.google.com";



int main()
{
    char* pass;
    char* p="hello";
    int i=0;

    printf("Enter password and press ENTER.\n \n");
    do
    {
        printf("Password: ");
        scanf( "%s",  pass);

        if(strcmp ( pass, p ) == 0)
        {
            printf("Correct Password. \n \n");
            i=10;
        }
        else
        {
            if(strcmp ( pass, "hint" ) == 0)
            {
                printf("Password Hint: Form of salutation. \n \n");
            }
            else
            {
                printf("Incorrect Password. \nType 'hint' for help. \n \n");
                i++;
            }
        }

        if (i == 3)
        {
            i++;
            printf("\n---- PROGRAM TERMINATED ----\n--- PRESS ANY KEY TO END ---\n");
            getch();
        }
    }
    while (i<4);

    if (i == 10)
    {
        strcat(internet, url);
        printf("Press ENTER to continue... \n");
        getch();
        //Open a program or file
        system (internet);
        printf("\n---- PROGRAM TERMINATED ----\n--- PRESS ANY KEY TO END ---\n");
        getch();
    }

    return 0;
}

supply in args when making the system call.

Space(s) separate the command from its argument and strcat() won't do that for you.

ok i got it with the shellexecute! thanks to everyone!!
though i still got some memory error at the end :S.
will anyone care to suggest something more?

Code:

#include <stdio.h>
#include <stdlib.h>
#include <windows.h>

int main()
{
    char* pass;
    char* p="hello";
    int i=0;

    printf("Enter password and press ENTER.\n \n");
    do
    {
        printf("Password: ");
        scanf( "%s",  pass);

        if(strcmp ( pass, p ) == 0)
        {
            printf("Correct Password. \n \n");
            i=10;
        }
        else
        {
            if(strcmp ( pass, "hint" ) == 0)
            {
                printf("Password Hint: Form of salutation. \n \n");
            }
            else
            {
                printf("Incorrect Password. \nType 'hint' for help. \n \n");
                i++;
            }
        }

    }
    while (i<3);

    if (i == 10)
    {
        printf("Opening program... \n\n");
                //Open a program or file
        ShellExecute(NULL, "open", "http://www.microsoft.com", NULL, NULL, SW_SHOWNORMAL);
        printf("Close program to contione. \nPress any key. \n\n");
        getch();
    }

    printf("\n---- PROGRAM TERMINATED ----\n--- PRESS ANY KEY TO END ---\n");
    getch();

    return 0;
}

this works..

system ("START www.website_name_here.com");
