C#中啓動另一個程序的有效方法

在工作過程中。技術總監給出了這樣一個有效的啓動程序的有效方法，現在和大家分享下：

 

private void btnCreate_Click(object sender, EventArgs e)
        ...{
            int hWnd = FindWindow(null, "test");//窗體的名稱
            //check if PowerReuse is launched or not
            //if yes, pass path of project to PowerReuse
            //or, launch PowerReuse with specifIEd parameter
            if (hWnd > 0)
            ...{
                MessageBox.Show("powerReuse has been launched already." + " " + hWnd.ToString());
                //SendMessage to PowerReuse
                return;
            }

            try
            ...{
                Process Main_P = new Process();
                //this path should be retrIEved from Windows Registry,
                //the loaction is written by Installter during process of installation.
                Main_P.StartInfo.FileName = @"C: est.exe";//運行的exe路徑
                
                //This URL is passed to PowerReuse to open
                Main_P.StartInfo.Arguments = @"C:Tempabc.prj";//運行時的參數

                Main_P.StartInfo.UseShellExecute = true;
                
                Main_P.Start();
                //
                //we have to wait for a while until UI has been initialized
                //
                Main_P.WaitForInputIdle(10000);

                //although UI has been initialzIEd,
                //it does not mean main form of application has been completed.
                //we may wait for another 10 seconds
                for (int i = 0; i < 100; i++)
                ...{
                    hWnd = FindWindow(null, "PowerReuse (Beta)");
                    //hWnd = Main_P.MainWindowHandle.ToInt32() ;
                    if (hWnd > 0) break;
        Thread.Sleep(100);
                }

                //Here, we check if PowerReuse is fully launched 
                if (hWnd == 0)
                ...{
                    //Handle exception
                    MessageBox.Show("We cannot find window handle of PowerReuse");
                }
                else
                ...{
                    //other handling
                    //
                    MessageBox.Show(hWnd.ToString() + " " + Main_P.MainWindowHandle.ToString() + " " + Main_P.MainWindowTitle);
                }
            }
            catch (Exception ex)
   ...{
                MessageBox.Show(ex.Message);
            }
        }
