 |
|
Hello,
I would change my application for Vista and I got a problem to fin the
username.Using this function my code is :
LPSTR utilisateur;
LPDWORD taille;
GetUserName(utilisateur,taille);
When I insspec the user name I obtain anything else that the user
name.Something strange in the pointer.
Must I do something else
I thank you in advance

Yes.
You have done no initialisation whatsoever in that code, just used
random values and handed them to a function. I'm surprised it isn't
crashing.
Something more like
char utilisateur[200] = { 0 };
DWORD taille = sizeof(utilisateur)/sizeof(utilisateur[0]);
if (GetUserName(&utilisateur[0], &taille) != 0)
{
...
}
(though I'd personally use vectors, using a two stage process to firstly
get the size, secondly get the content into a resized vector).
