实验内容:
写一个注册窗口,然后在另一个窗体中显示注册内容。
先写个注册窗体:7个lable，5个textbox,1个combobox,1个picturebox，3个button和1个openfiledialog
按下图进行摆放
Form1.cs 代码如下:
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 实验1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
}
private void button3_Click(object sender, EventArgs e)
{
DialogResult result = textureFileOpen.ShowDialog();
if(result==DialogResult.OK)
{
string fileName = textureFileOpen.FileName;
pictureBox1.Load(fileName);
button3.Text = "更改头像";
}
}
private void button2_Click(object sender, EventArgs e)
{
///// 清空数据 /////////
textBox1.Text = null;
textBox2.Text = null;
textBox3.Text = null;
textBox4.Text = null;
textBox5.Text = null;
comboBox1.Text = null;
pictureBox1.Image = null;
button3.Text = "上传头像";
}
private void button1_Click(object sender, EventArgs e)
{
//////////安全性检查///////////////
if (textBox1.Text == "" || textBox1.Text == "" || textBox1.Text == "" || textBox1.Text == ""||comboBox1.Text=="")
{
MessageBox.Show("你还有内容没填好!","警告:",MessageBoxButtons.OKCancel);
}
else if(textBox2.Text!=textBox3.Text)
{
MessageBox.Show("密码不一致,请再次确定!","提示:",MessageBoxButtons.OK);
}else
{
Form2 f2= new Form2();
f2.Owner = this;
f2.Show();
}
}
private void textBox3_TextChanged(object sender, EventArgs e)
{
label8.Text = "显示密码";
}
private void label8_Click(object sender, EventArgs e)
{
if(label8.Text == "显示密码")
{
textBox3.UseSystemPasswordChar = false;
textBox2.UseSystemPasswordChar = false;
label8.Text = "隐藏密码";
}
else if (label8.Text == "隐藏密码")
{
label8.Text = "显示密码";
textBox2.UseSystemPasswordChar = true;
textBox3.UseSystemPasswordChar = true;
}
}
private void button4_Click(object sender, EventArgs e)
{
DialogResult result = MessageBox.Show("你确定要退出吗？","提示:",MessageBoxButtons.OKCancel);
if(result==DialogResult.OK)
{
this.Close();
}
}
private void textBox4_KeyPress(object sender, KeyPressEventArgs e)
{
///////控制只能输入数值 8是backspace键的ASII码//////////
if (!(Char.IsNumber(e.KeyChar))&&e.KeyChar!=(char)8)
{
e.Handled = true;
}
}
}
}
注意:
1.picturebox有个sizemode属性，该属性是控制图像的显示:
Normal:表示图像被置于picturebox的左上角如果图像比它包含的picturebox大，则该图像将被剪裁掉.
stretchImage:表示picturebox中的图像被拉伸或收缩，以适合picturebox的大小
Autosize:表示调整picturebox大小，使其等于所包含图像的大小。
CenterImage:如果picturebox比图像大,则图像将局中显示，如果picturebox比图像小，则将图像居于picturebox 的中心，而边缘将被剪裁掉
zoom:表示图像大小按原有的大小比例增加或减小.
2.在Form的属性中有canclebutton这个属性，当该属性为(无)时，按下Esc键可退出程序.
另一个窗体form2:
10个lable,1个picturebox,1个textbox，1个button
如下图摆放:
Form2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 实验1
{
public partial class Form2 : Form
{
public Form2()
{
InitializeComponent();
}
private void Form2_Load(object sender, EventArgs e)
{ //把窗体1的控件实例化传递
TextBox Tex_0 = Application.OpenForms["Form1"].Controls["textBox1"] as TextBox;
TextBox Tex_1 = Application.OpenForms["Form1"].Controls["textBox4"] as TextBox;
TextBox Tex_2 = Application.OpenForms["Form1"].Controls["textBox5"] as TextBox;
ComboBox Tex_3 = Application.OpenForms["Form1"].Controls["comboBox1"] as ComboBox;
PictureBox pic = Application.OpenForms["Form1"].Controls["pictureBox1"] as PictureBox;
//信息的传递
if(Tex_0!=null)
{
label9.Text = "尊敬的" + Tex_0.Text + "你好,请核对一下以下信息!";
label2.Text = Tex_0.Text;
}
if (Tex_1!= null)
{
label5.Text = Tex_1.Text;
}
if (Tex_2 != null)
{
textBox.Text = Tex_2.Text;
}
if (Tex_3 != null)
{
label3.Text = Tex_3.Text;
}
if(pic!=null)
{
pictureBox1.Image = pic.Image;
}
}
private void textBox5_TextChanged(object sender, EventArgs e)
{
}
private void button1_Click(object sender, EventArgs e)
{
this.Close();
}
}
}
注意:
1.textbox的readonly属性设置成true(只能读取)
2. textbox的Scrollbars设置成vertical(垂直滚动条)【Horizontal(水平滚动条),both(水平加垂直滚动条)】
