分享如何在程序里模拟在cmd里用管理员权限运行一条指令？
win7下，我想执行net user administrator /active:yes这样一条指令，用system()函数执行时返回错误，返回错误是“发生系统错误 5 拒绝访问”，原来是没有管理员权限，用手动右键点击cmd.exe，选择使用管理员权限运行就ok了，但在代码里如何能模拟管理员权限的cmd来运行一条指令呢？

啊，，哈哈 搞定啦，你那个命令差一点点就成了，改成这样就好了
ShellExecute(0,"runas", LPCSTR("cmd.exe"),LPCSTR("/c net user administrator /active:yes"),"",SW_HIDE);
多谢各位的帮助。。。

生成一个临时文本文件tmp.bat，内容为
runas /noprofile /user:mymachine\administrator "cmd /c \"net user administrator /active:yes\""

试试看。
CreateProcessAsUser
The CreateProcessAsUser function creates a new process and its primary thread. The new process then executes a specified executable file. The CreateProcessAsUser function is similar to the CreateProcess function, except that the new process runs in the security context of the user represented by the hToken parameter. By default, the new process is non-interactive, that is, it runs on a desktop that is not visible and cannot receive user input. Also, by default, the new process inherits the environment of the calling process, rather than the environment associated with the specified user.
BOOL CreateProcessAsUser(
HANDLE hToken, // handle to a token representing the logged-on user
LPCTSTR lpApplicationName, // pointer to name of executable module
LPTSTR lpCommandLine, // pointer to command line string
LPSECURITY_ATTRIBUTES lpProcessAttributes, // process security attributes
LPSECURITY_ATTRIBUTES lpThreadAttributes, // thread security attributes
BOOL bInheritHandles, // whether new process inherits handles
DWORD dwCreationFlags, // creation flags
LPVOID lpEnvironment, // pointer to new environment block
LPCTSTR lpCurrentDirectory, // pointer to current directory name
LPSTARTUPINFO lpStartupInfo, // pointer to STARTUPINFO
LPPROCESS_INFORMATION lpProcessInformation // pointer to PROCESS_INFORMATION
);

ShellExecuteA(0,"runas","cmd","","",1);
这样是以管理员权限打开了cmd窗口，但怎么运行net user administrator /active:yes指令呢？
