我做了一个程序,从客户端发送UDP数据包到服务器这里是发送器代码

import java.io.IOException;
import java.net.*;

/**

public class JavaApplication9 {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) throws UnknownHostException, SocketException, IOException  {
        // TODO code application logic here
        byte[] buffer = {10,23,12,31,43,32,24};
        byte [] IP={-64,-88,1,106};
        InetAddress address = InetAddress.getByAddress(IP);
        DatagramPacket packet = new DatagramPacket(
                buffer, buffer.length, address, 57
                );
        DatagramSocket datagramSocket = new DatagramSocket();
        datagramSocket.send(packet);
        System.out.println(InetAddress.getLocalHost().getHostAddress());


    }
}

接收器代码功能是

public void run(){

    try{
        DatagramSocket serverSocket = new DatagramSocket(port); …

我正在尝试制作一个程序,当按下某个名为hide的按钮时,图像会消失.

我知道在Windows窗体应用程序中它会是这样的:

    pictureBox1->Visible=true/false;

但该代码在MFC中不起作用

我在MFC中的代码是

     Cstatic pictureBox1 =(Cstatic)Getdialogitem(IDC_IMAGE1);
     pictureBox1->Visible=false;
