Credential Providers V2 Active for All users(Tiles) - c++

Question

I use sample code of "Credential Providers in Windows 10". I develop my code and change it very good.
But I have some problem with it:
It is not enable (Show tile) for all users in my windows. (Show for one user only)
I See this questions:
https://stackoverflow.com/a/31247811/3477587
Credential provider not displayed for all users (Other user included)
So I change my code but when use from my DLL win-login don't load and I must delete in in safe-mode to I can enter to my windows without Credential Providers.
I change my code as follow:
std::vector<CSamanCredential*> _pCredential; // SampleV2Credential
HRESULT CSamanProvider::GetCredentialAt(
DWORD dwIndex,
_Outptr_result_nullonfailure_ ICredentialProviderCredential** ppcpc)
{
HRESULT hr = E_INVALIDARG;
*ppcpc = nullptr;
hr = _pCredential[dwIndex]->QueryInterface(IID_PPV_ARGS(ppcpc));
return hr;
}
HRESULT CSamanProvider::GetCredentialCount(
_Out_ DWORD* pdwCount,
_Out_ DWORD* pdwDefault,
_Out_ BOOL* pbAutoLogonWithDefault)
{
*pdwDefault = CREDENTIAL_PROVIDER_NO_DEFAULT;
*pbAutoLogonWithDefault = FALSE;
if (_fRecreateEnumeratedCredentials)
{
_fRecreateEnumeratedCredentials = false;
_ReleaseEnumeratedCredentials();
_CreateEnumeratedCredentials();
}
DWORD dwUserCount = 0;
HRESULT hr;
if (_pCredProviderUserArray != nullptr) {
hr = _pCredProviderUserArray->GetCount(&dwUserCount);
}
if ((dwUserCount == 0) || (IsOS(OS_DOMAINMEMBER) == 1)) {
dwUserCount += 1;//display additional empty tile
}
*pdwCount = dwUserCount;
return S_OK;
}
void CSamanProvider::_ReleaseEnumeratedCredentials()
{
DWORD dwUserCount;
_pCredProviderUserArray->GetCount(&dwUserCount);
for (DWORD i = 0; i < dwUserCount; i++) {
if (_pCredential[i] != nullptr)
{
_pCredential[i]->Release();
_pCredential[i] = nullptr;
}
}
}
So I change other place in my code but I don't get result.

Answer 1

You must follow instructions in the posts you mentioned.
As a indirect response to ICredentialProviderSetUserArray::SetUserArray you must prepare tile for each user in the supplied list.
Later your tiles will be asked for ICredentialProviderCredential2::GetUserSid.
There your tile must return one of SIDs from the list of previous step.
When I was implementing this logic had to redesign a huge part of my code to support this feature.

Answer 2

I read this code. This is very helpful for knowing instruction and other details.

This code (C++) active CP for all user on computer.
