我试图在对象上设置安全权限.这是代码:
PROCESS_INFORMATION pi = {0};
STARTUPINFO si = {0};
si.cb = sizeof(STARTUPINFO);
CreateProcess("C:\\AP\\DataBase\\dbntsrv.exe", NULL, NULL, NULL, FALSE, CREATE_NO_WINDOW, NULL, "C:\\ADP\\SQLBase", &si, &pi);
result = SetSecurityInfo(pi.hProcess, SE_WINDOW_OBJECT, PROCESS_TERMINATE, NULL, NULL, NULL, NULL);

但它给了我编译时错误'SetSecurityInfo' : undeclared identifier..和'SE_WINDOW_OBJECT' : undeclared identifier..任何想法为什么会发生这种情况?谢谢

似乎编译器没有识别Move,所以bestLine没有被声明.我认为这可能是一个循环依赖,并尝试声明一个不完整的类型Move,但它没有任何影响.有人可以解释我错过的东西吗?
