登陆框控件
|
好久以前作的东西,最近拿出来溜溜,最近一直没有作应用程序方面的东西了,有点生疏! 希望我的这篇东西能对您有所帮助,大家共同探讨共同进步,此文章比较简单!是作一个通用的登陆框控件!
首先建一解决项目LoginControl,添加一个类库的项目LoginControl,然后添加用户控件ctlLogin
然后在ctlLogin.cs文件中写代码
//ctlLogin.cs
using System;
using System.Collections;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Windows.Forms;
using System.Text;
namespace LoginControl
{
///
/// ctlLogin 的摘要说明。
///
public class ctlLogin : System.Windows.Forms.UserControl
{
private System.Windows.Forms.Panel panel1;
private System.Windows.Forms.Label lHeader;
private System.Windows.Forms.Label lText;
private System.Windows.Forms.Button btnLogin;
private System.Windows.Forms.Label lPassword;
private System.Windows.Forms.Label lUsername;
private System.Windows.Forms.TextBox txtPassword;
private System.Windows.Forms.TextBox txtUsername;
private System.Windows.Forms.PictureBox pictureBox1;
private System.Windows.Forms.ErrorProvider errorProvider;
///
/// 必需的设计器变量。
///
private System.ComponentModel.Container components = null;
public event System.EventHandler Successful;
public event System.EventHandler Failed;
private ArrayList strUsername=new ArrayList();
private ArrayList strPassword=new ArrayList();
private int index=-1;
private string ErrMsg = "请输入正确的用户名和密码!";
public ctlLogin()
{
// 该调用是 Windows.Forms 窗体设计器所必需的。
InitializeComponent();
// TODO: 在 InitializeComponent 调用后添加任何初始化
strUsername.Clear();
strPassword.Clear();
}
///
/// 清理所有正在使用的资源。
///
protected override void Dispose( bool disposing )
{
if( disposing )
{
if(components != null)
{
components.Dispose();
}
}
base.Dispose( disposing );
}
#region 组件设计器生成的代码
///
/// 设计器支持所需的方法 - 不要使用代码编辑器
/// 修改此方法的内容。
///
private void InitializeComponent()
