C#--第十一周任务一登录窗体与主窗体
首先是登陆窗体:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class frmLogin : Form
{
public frmLogin()
{
InitializeComponent();
}
private void frmLogin_Load(object sender, EventArgs e)
{
}
Form frmMain;
private void button1_Click(object sender, EventArgs e)
{//要求：在登录窗体中，假设当用户输入账号为“zhangsan”，且密码为“123”（密码显示为*）
//，则通过登录，销毁登录窗体，同时打开主窗体。否则，给出错误提示，如“账号或密码错误”
if(textBox1.Text.Equals("zhangsan")&&textBox2.Text.Equals("123"))
{
frmMain = new frmMain();
frmMain.Show();
}
else
{
MessageBox.Show("您的账号或密码错误");
}
}
private void textBox1_TextChanged(object sender, EventArgs e)
{
}
private void textBox2_TextChanged(object sender, EventArgs e)
{
}
}
}
接着是主窗体:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class frmMain : Form
{
public frmMain()
{
InitializeComponent();
}
private void frmMain_Load(object sender, EventArgs e)
{
}
private void 文件ToolStripMenuItem_Click(object sender, EventArgs e)
{
}
private void 打开主窗体1ToolStripMenuItem_Click(object sender, EventArgs e)
{
frm子窗体1 f = new frm子窗体1();
f.Show();
f.MdiParent = this;
}
private void 打开主窗体2ToolStripMenuItem_Click(object sender, EventArgs e)
{
foreach (var item in this.MdiChildren)
{
item.Dispose();
}
frm子窗体2 f1 = new frm子窗体2();
f1.Show();
f1.MdiParent = this;
}
private void frmMain_Load_1(object sender, EventArgs e)
{
}
}
}
最后是两个子窗体
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class frm子窗体1 : Form
{
public frm子窗体1()
{
InitializeComponent();
}
private void frm子窗体1_Load(object sender, EventArgs e)
{
}
}
}
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class frm子窗体2 : Form
{
public frm子窗体2()
{
InitializeComponent();
}
private void frm子窗体2_Load(object sender, EventArgs e)
{
}
}
}
