Hi all,
Using C++ .net I have developed a new Gina.dll to replace the one that windows has in order to add support to Biomatrics under windows NT.
At the end of the programming phase i detected that the Logon Scripts were executed,But In login Dialog box last successfully login Username not shown in textbox of 'usernsme'
I have use "ImpersonateLoggedOnUser" for this problem ut prolem not solved.
I have read as many docs as could, but there is something missing i dont see.
//////Code
ImpersonateAndGetUserName(HANDLE hToken, wchar_t* name, int cch) {
bool result = false;
if (ImpersonateLoggedOnUser(hToken)) {
DWORD cchName = cch;
if (GetUserName(name, &cchName))
result = true;
else LCF1(L"GetUserName failed: %d", GetLastError());
RevertToSelf();
}
else LCF1(L"ImpersonateLoggedOnUser failed: %d", GetLastError());
return result;
}
