我想在5分钟后自动洗牌.Windows窗体包含多个查询,多个视频,多个powerpoint.
我有三种窗体形式,如下所示.
表格1代码:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace Daily_System {
public partial class Form1: Form {
public Form1() {
InitializeComponent();
timer1.Enabled = true;
timer1.Interval = 5000;
timer1.Tick += timer1_Tick;
timer1.Start();
}
private void Form1_Load(object sender, EventArgs e) {
this.WindowState = FormWindowState.Maximized;
CenterToScreen();
}
private Timer timer1 = new Timer();
private void button1_Click_1(object sender, EventArgs e) {
this.WindowState = FormWindowState.Minimized;
Form2 f = new Form2(); // …c# powerpoint windows-forms-designer winforms visual-studio-2012
