Start a process using wmi on a remote computer - c++

Question

I used this code provided on msdn to connect to remote computer to check processes, but I don't understand how to start a process on remote PC using wmi in c++.
IWbemServices *pSvc = NULL;
// Get the user name and password for the remote computer
CREDUI_INFO cui;
bool useToken = false;
bool useNTLM = true;
wchar_t pszName[CREDUI_MAX_USERNAME_LENGTH+1] = {0};
wchar_t pszPwd[CREDUI_MAX_PASSWORD_LENGTH+1] = {0};
wchar_t pszDomain[CREDUI_MAX_USERNAME_LENGTH+1];
wchar_t pszUserName[CREDUI_MAX_USERNAME_LENGTH+1];
wchar_t pszAuthority[CREDUI_MAX_USERNAME_LENGTH+1];
BOOL fSave;
DWORD dwErr;
memset(&cui,0,sizeof(CREDUI_INFO));
cui.cbSize = sizeof(CREDUI_INFO);
cui.hwndParent = NULL;
// Ensure that MessageText and CaptionText identify
// what credentials to use and which application requires them.
cui.pszMessageText = TEXT("Press cancel to use process token");
cui.pszCaptionText = TEXT("Enter Account Information");
cui.hbmBanner = NULL;
fSave = FALSE;
dwErr = CredUIPromptForCredentials(
&cui, // CREDUI_INFO structure
TEXT(""), // Target for credentials
NULL, // Reserved
0, // Reason
pszName, // User name
CREDUI_MAX_USERNAME_LENGTH+1, // Max number for user name
pszPwd, // Password
CREDUI_MAX_PASSWORD_LENGTH+1, // Max number for password
&fSave, // State of save check box
CREDUI_FLAGS_GENERIC_CREDENTIALS |// flags
CREDUI_FLAGS_ALWAYS_SHOW_UI |
CREDUI_FLAGS_DO_NOT_PERSIST);
if(dwErr == ERROR_CANCELLED)
{
useToken = true;
}
else if (dwErr)
{
cout << "Did not get credentials " << dwErr << endl;
pLoc->Release();
CoUninitialize();
return 1;
}
// change the computerName strings below to the full computer name
// of the remote computer
if(!useNTLM)
{
StringCchPrintf(pszAuthority, CREDUI_MAX_USERNAME_LENGTH+1, L"kERBEROS:%s", L"COMPUTERNAME");
}
// Connect to the remote root\cimv2 namespace
// and obtain pointer pSvc to make IWbemServices calls.
//---------------------------------------------------------
hres = pLoc->ConnectServer(
_bstr_t(L"\\\\COMPUTERNAME\\root\\cimv2"),
_bstr_t(useToken?NULL:pszName), // User name
_bstr_t(useToken?NULL:pszPwd), // User password
NULL, // Locale
NULL, // Security flags
_bstr_t(useNTLM?NULL:pszAuthority),// Authority
NULL, // Context object
&pSvc // IWbemServices proxy
);
if (FAILED(hres))
{
cout << "Could not connect. Error code = 0x"
<< hex << hres << endl;
pLoc->Release();
CoUninitialize();
return 1; // Program has failed.
}
