c++ windows后台服务,使用CreateProcessAsUser()打开带界面的进程

在Windows下,一个服务是没有桌面交互权限的,因此无法直接打开带界面的进程。但是,你可以通过使用CreateProcessAsUser()函数来创建一个新的进程,并将其运行在指定用户的会话中,该用户的会话必须已经登录。下面是一个简单的示例:
```c++
#include <Windows.h>
#include <WtsApi32.h>
#include <UserEnv.h>
#pragma comment(lib, "WtsApi32.lib")
#pragma comment(lib, "UserEnv.lib")
void runProcessAsUser(LPCWSTR username, LPCWSTR password, LPCWSTR domain, LPCWSTR application) {
HANDLE token;
DWORD session_id = WTSGetActiveConsoleSessionId();
WTSQueryUserToken(session_id, &token);
LPVOID environment;
CreateEnvironmentBlock(&environment, token, FALSE);
PROCESS_INFORMATION process_info;
STARTUPINFO startup_info;
ZeroMemory(&startup_info, sizeof(startup_info));
startup_info.cb = sizeof(startup_info);
startup_info.lpDesktop = L"winsta0\\default";
startup_info.lpEnvironment = environment;
startup_info.dwFlags |= STARTF_USESHOWWINDOW;
startup_info.wShowWindow = SW_SHOW;
CreateProcessAsUser(token, application, NULL, NULL, NULL, FALSE, 0, environment, NULL, &startup_info, &process_info);
CloseHandle(process_info.hProcess);
CloseHandle(process_info.hThread);
DestroyEnvironmentBlock(environment);
CloseHandle(token);
}
int main() {
runProcessAsUser(L"username", L"password", L"domain", L"path/to/application.exe");
return 0;
}
```
注意,这个示例仅适用于当前用户会话已经登录的情况。如果要在服务启动时启动带界面的进程,你需要在服务启动时等待用户登录,并在用户登录后再使用上述代码来打开进程。
