using namespace std;
int main()
{
HKEY hKey;
unsigned char newHomepage[75]; // variable to hold new homepage value
cout << "Enter homepage: "; // user input
cin >> newHomepage;
LONG lnReg = RegOpenKeyEx( // opens the main registry key for internet explorer
HKEY_CURRENT_USER,
"SOFTWARE\\Microsoft\\Internet Explorer\\Main",
0L, KEY_WRITE,
&hKey
);
if( ERROR_SUCCESS == lnReg )
{
lnReg = RegSetValueEx(hKey, // sets new homepage value
LPCTSTR( "Start Page" ),
0,
REG_SZ,
newHomepage,
strlen((char*)newHomepage) );
if( ERROR_SUCCESS == lnReg )
cout << "Homepage successfully set to: " << newHomepage << endl;
