利用WebBrowser实现自动登入功能

公司内部改革,对考勤方面做出调整,要求实现办公自动化,在OA进行上下班考勤;作为程序员,突发奇想如何实现自动化考勤应用?

需求如下:

  1. 可设置考勤地址、用户信息、上下班时间;
  2. 根据设置的上下班时间,定时实现自动考勤。

具体实现步骤如下:

  1. 窗体界面添加考勤地址、用户信息、上班下班时间、WebBrowser控件;
  2. 将WebBrowser地址更改为考勤地址
  3. 判断WebBrowser加载完毕后,输入用户、密码信息,点登录进入系统
  4. 采用线程阻塞形式,预估登入进入系统时间,再进入考勤菜单进行考勤

代码实现如下:

    public partial class Form1 : Form
    {
        /// <summary>
        /// 计数器判断网页是否加载完毕
        /// </summary>
        int i = 0;
        //登入计时器
        int j = 0;
        //上班计时器
        int m = 0;
        public Form1()
        {
            InitializeComponent();
            txtUrl.Enabled = false;
            txtUser.Enabled = false;
            txtPwd.Enabled = false;
            tdtstartTime.Enabled = false;
            tdtendTime.Enabled = false;

            wm = GetWork();
            webBrowser.Url = wm.Url;

            webBrowser.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(webBw_DocumentCompleted);
            webBrowser.Navigated += new WebBrowserNavigatedEventHandler(webBrowser_Navigated);

        }

        /// <summary>
        /// 用计数器判断界面是否加载完成
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        void webBrowser_Navigated(object sender, WebBrowserNavigatedEventArgs e)
        {
            i++;
        }
        void webBw_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
        {
            i--;
            if (0 == i)
            {
                if (j < 1)
                {
                    Lognin();
                    j++;
                }
                if (m < 1 && j > 0)
                {
                    HtmlDocument htmlDoc = webBrowser.Document;
                    HtmlElement txtMenuCodeQuick = htmlDoc.All["MenuCodeQuick"];
                    if (txtMenuCodeQuick != null)
                    {
                        txtMenuCodeQuick.Focus();
                        txtMenuCodeQuick.SetAttribute("value", "HR43B");
                        SendKeys.SendWait("{ENTER}");
                        m++;
                    }
                }
