我正在尝试创建一个流程来启动需要UI的应用程序。因此它不能在 session 0中。
我的想法是获取当前登录用户的winlogon.exe的进程ID。这样,我可以复制winlogon token 并使用CreateProcessAsUser函数运行我的应用程序。
到目前为止我的代码:(当需要运行我想要的应用程序时,将调用此代码)

#include <windows.h>
#include <tlhelp32.h>
#include <tchar.h>

this function()
{
  HANDLE hProcessSnap;
  HANDLE hProcess;
  PROCESSENTRY32 pe32;
  DWORD dwPriorityClass;

  // Take a snapshot of all processes in the system.
  hProcessSnap = CreateToolhelp32Snapshot( TH32CS_SNAPPROCESS, 0 );

  // Set the size of the structure before using it.
  pe32.dwSize = sizeof( PROCESSENTRY32 );

  //get the active session id
  DWORD sessionID = WTSGetActiveConsoleSessionId();

  // Now walk through the snapshot of processes
  //I want to narrow this down to processes called winlogon
  //if multiple users logged on system i want to make sure the active user
  //will get the application run the their screen
  do
  {
  // Retrieve the priority class.
    dwPriorityClass = 0;

    //here i want to compare the sessionID with session IDs of each winlogon process
    //stuck for implementation here
    //when i find a match i can use the processID to gain the token and create
    //a duplicate so it can be used in CreateAsUser function.
  }while( Process32Next( hProcessSnap, &pe32 ) );

 }

因此,基本上,我需要一些帮助来将进程的快照范围缩小到“winlogon”,并遍历这些进程的 session ID以匹配 Activity 用户的sessionID。
先谢谢了

最佳答案

您可以使用ProcessIdToSessionId获取与“winlogon.exe”匹配的每个进程的 session ID,然后将结果与WTSGetActiveConsoleSessionId进行比较。

您可以在循环中使用以下代码片段:

if (_wcsicmp(pe32.szExeFile, L"winlogon.exe") == 0)
{
    DWORD ProcessSessionId = 0;
    ProcessIdToSessionId(pe32.th32ProcessID, &ProcessSessionId);
    if (ProcessSessionId == sessionID)
    {
        DoYourMagic(pe32.th32ProcessID);
        break;
    }
}
