CreateProcessAsUser的用法

最近太忙了，忙着弄公司的产品，现在好不容易有点时间来写点东西，代码很乱，没有整理，只是提供思路

DWORD __stdcall INTER_GetExplorerToken(OUT PHANDLE phExplorerToken )
{
DWORD dwStatus = ERROR_FILE_NOT_FOUND ;
BOOL bRet = FALSE ;
HANDLE hProcess = NULL ;
HANDLE hProcessSnap = NULL ;
char szExplorerPath[MAX_PATH] = { 0 } ;
char FileName[MAX_PATH] = { 0 } ;
PROCESSENTRY32 pe32 = { 0 } ;
__try
{
GetWindowsDirectory( szExplorerPath , MAX_PATH ) ;
strcat( szExplorerPath , "//Explorer.EXE" ) ;
hProcessSnap = CreateToolhelp32Snapshot( TH32CS_SNAPPROCESS , 0 ) ;
if( hProcessSnap == INVALID_HANDLE_VALUE )
{
dwStatus = GetLastError() ;
__leave ;
}
pe32.dwSize = sizeof( PROCESSENTRY32 ) ;
if( !Process32First( hProcessSnap, &pe32 ))
{
dwStatus = GetLastError() ;
__leave ;
}
do {
hProcess = OpenProcess(
PROCESS_ALL_ACCESS ,
FALSE ,
pe32.th32ProcessID ) ;
if( NULL != hProcess )
{
DWORD (__stdcall *GMFNE)(HANDLE hProcess,
HMODULE hModule,
LPTSTR lpFilename,
DWORD nSize);
HMODULE hPsapi=LoadLibrary("PSAPI");
if ( ! hPsapi )
{
dwStatus = GetLastError() ;
break ;
}
GMFNE=(DWORD (__stdcall *) (HANDLE, HMODULE,LPTSTR,DWORD))GetProcAddress(hPsapi,"GetModuleFileNameExA");
if ( GMFNE(hProcess , NULL , FileName , MAX_PATH) )
{
if( !strcmpi( FileName , szExplorerPath ))
{
HANDLE hToken ;
if( OpenProcessToken( hProcess , TOKEN_ALL_ACCESS , &hToken ))
{
* phExplorerToken = hToken ;
dwStatus = 0 ;
}
break ;
}
}
CloseHandle ( hProcess ) ;
hProcess = NULL ;
}

} while( Process32Next( hProcessSnap, &pe32 )) ;
}
__finally
{
if( NULL != hProcess )
{
CloseHandle( hProcess ) ;
}
if( NULL != hProcessSnap )
{
CloseHandle ( hProcessSnap ) ;
}
}
return dwStatus ;
}
