Do the following…
[sourcecode language=’cpp’]GUID guId = { 0 };
CoCreateGuid( &guId );
// or
UUID uid = { 0 };
UuidCreate( &uid );[/sourcecode]
For converting to string use…
[sourcecode language=’cpp’]PUCHAR pChar = 0;
// Convert to string
UuidToString( &uid, &pChar );
MessageBox( NULL, (char*)pChar, NULL, MB_OK );
//Don’t forget to free allocated string
RpcStringFree( &pChar );[/sourcecode]
