Question

我正在使用C＃创建一个客户端，以使用一些示例连接到bopup。作为Windows应用程序运行时，句柄的值为0，而作为控制台应用程序运行时，值为> 0。为了使窗体内的主窗口句柄生效，我需要做些其他事情吗？

控制台：

static void Main(string[] args)
    {
        string error = null;
        uint refResult = 0;

        CSCLIENTLib.ServerClientVB client = new CSCLIENTLib.ServerClientVB();

        try
        {
            IntPtr handle = Process.GetCurrentProcess().MainWindowHandle;

            string server = "localhost";
     //       Console.WriteLine(server + "|" + 0 + "|" + (byte)VBClientType.Messenger + "|" + (uint)handle + "|" + refResult);
            client.Initialize(server, 0, (byte)VBClientType.Messenger, (uint)handle, ref refResult);


        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.ToString());

            client.GetEventDescription(refResult, ref error);
            Console.WriteLine(error);
        }
}

作为Windows窗体应用程序：

 public partial class Form1 : Form
    {
       string error = null;
       uint refResult = 0;
        private static CSCLIENTLib.ServerClientVB client;
        IntPtr handle;

        public Form1()
        {
            InitializeComponent();

            init_connection();
        }

  private void init_connection()
        {
            client = new CSCLIENTLib.ServerClientVB();
            try
            {
                handle = Process.GetCurrentProcess().MainWindowHandle;
                string server = "localhost";
                MessageBox.Show(server + "|" + 0 + "|" + (byte)VBClientType.Messenger + "|" + (uint)handle + "|" + refResult);
                client.Initialize(server, 0, (byte)VBClientType.Messenger, (uint)handle, ref refResult);
            }
            catch (Exception ex)
            {
                // Console.WriteLine(ex.ToString());
                MessageBox.Show("ERROR: " + ex.ToString());
                client.GetEventDescription(refResult, ref error);
                // Console.WriteLine(error);
                MessageBox.Show("ERROR: " + error.ToString());

            }
    }
    }

如果要使用当前表单的句柄，请使用Handle属性（this.Handle）。

handle = this.Handle;

C＃intptr没有得到处理
