How to open a URL in the default web browser?

This is easily done by calling ShellExecute() HTTP and FTP URLs should be processed by both Netscape and IE: the "default" browser will handle them. Other protocols such as mailto and news may also handled by the browser. IE4 adds handlers for things like "Callto:" for Net Meeting contacts.

#include "windows.h"

 #include "shellapi.h"

 //link in the library

#pragma comment(lib,"shell32.lib")

int main(int argc, char *const argv[])

{

    ShellExecute(NULL,"open", "http://coderdreambook.blogspot.in/", "", "c:\\", SW_SHOWNORMAL);

    return 0;

}
