用C#实现启动另一程序的方法

一段实例代码，程序的目的是使用C#实现启动另一程序的方法。

　　private void btnCreate_Click(object sender, EventArgs e)

　　...{

　　int hWnd = FindWindow(null, "test");//窗体名称

　　//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";//

exe路径　

//This URL is passed to PowerReuse to open

　　Main_P.StartInfo.Arguments = @"C:Tempabc.prj";//参数　　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);

　　}

　　}
