Char shellchar [256]; // defines the command line
DWORD dwtype;

// Open the Registry root keyword
If (regopenkey (hkey_classes_root, null, & hkroot) = error_success)
{
// Open the subkeyword
If (regopenkeyex (hkroot,
"Htmlfile // shell // open // command ",
0,
Key_all_access,
& Hsubkey) = error_success)
{
// Read the registry and obtain the command line of the default browser
Regenumvalue (hsubkey,
0,
Valuename,

Null,
& Dwtype,
Datavalue,
& Cbdatavalue );
// Call parameter (Home Address) Assignment
Strcpy (shellchar, (char *) datavalue );
