请教:一个Winfrom如何防止远程登录开多个程序?
服务器是win2003,程序是放在“启动”那里自动启动的,但多个用户远程登录后会造成程序开多个,有什么办法防止程序在windows系统中只开一个? (不做成“服务”的前提下),先谢谢了!!!

C# code
不同用户没试过试过,我有当前用户不能多开的 你试试不同用户行不行。
        #region 程序只运行一次
        /// <summary>
        /// 程序只运行一次
        /// </summary>
        /// <returns>null</returns>
        public static Process RunningInstance()
        {
            Process current = Process.GetCurrentProcess();
            Process[] processes = Process.GetProcessesByName(current.ProcessName);
            //Loop through the running processes in with the same name 
            foreach (Process process in processes)
            {
                //Ignore the current process 
                if (process.Id != current.Id)
                {
                    //Make sure that the process is running from the exe file. 
                    if (Assembly.GetExecutingAssembly().Location.Replace("/", "\\") == current.MainModule.FileName)
                    {
                        //Return the other process instance. 
                        return process;
                    }
                }
            }
            //No other instance was found, return null. 
            return null;
        } 
        #endregion
