利用VB提取HTML文件中的EMAIL地址
| 电子邮件(EMAIL)是INTERNET上应用最广泛的一种服务之一。我们每天都在使用电子邮件,有时为了宣传我们的产品、网站等,更是离不开电子邮件,这就需要收集很多的EMAIL地址。下面我们将向大家介绍用VB自编一个EMAIL地址提取器,用来提取保存在我们硬盘中的HTML文件中所包含的EMAIL地址。 |
| 进入VB,选择“标准EXE”新建一工程,选择“工程”菜单下的“引用”,选中Microsoft scripting Runtime”,然后再选择“工程”菜单中的“部件”,在弹出的对话框中选择“Microsoft common dialog control 6.0”,在工具箱中加入通用对话框控件。接下来在默认窗体FORM1上添加三个标签控件,一个文本框控件text1,一个列表框控件LIST1,并命名为lstemail,三个命令command1~command3,其Caption属性分别设置为“提取”、“整理”、“保存”,设置完成的界面如下图所示: |
|
| Dim X, Y, St1, St2, tmpY As Integer |
| Private Sub StripEmail(FilePath As String) |
| Dim tmpEmail1, tmpEmail2 As String |
| Open FilePath For Input As #1 |
| For X = 1 To Len(tmpEmail1) |
| tmpEmail2 = Mid(tmpEmail1, X, 7) |
| If tmpEmail2 = "mailto:" Then |
| For Y = 1 To Len(tmpEmail1) |
| tmpEmail2 = Mid(tmpEmail1, tmpY, 1) |
| If tmpEmail2 = Chr(34) Or tmpEmail2 = "?" Then |
| tmpEmail2 = Mid(tmpEmail1, St1 + 7, ((St2 - St1) - 7)) |
| If (Left(tmpEmail2, 2) <> "//") And (Left(tmpEmail2, 1) <> " ") Then |
| lstEmail.AddItem tmpEmail2 |
| Private Sub Command1_Click() |
| Dim fs As New FileSystemObject ' 建立 FileSystemObject |
| Dim fd As Folder ' 定义 Folder 对象 |
| Set fd = fs.GetFolder(Text1) |
| Screen.MousePointer = vbHourglass |
| FindFile fd, "*.htm" 'Text1.Text |
| Screen.MousePointer = vbDefault |
| Sub FindFile(fd As Folder, FileName As String) |
| Dim sfd As Folder, f As File |
| If UCase(f.Name) Like UCase(FileName) Then |
| lblEmail = "已查找到的地址数为: " & lstEmail.ListCount |
| For Each sfd In fd.SubFolders |
| FindFile sfd, FileName ' 循环查找 |
| Private Sub Command2_Click() |
| For i = 0 To lstEmail.ListCount - 1 |
| For X = 0 To lstEmail.ListCount - 1 |
| If LCase(lstEmail.List(X)) = LCase(lstEmail.List(i)) Then |
| lblEmail = "共有" & lstEmail.ListCount & "个地址" |
| Private Sub Command3_Click() |
| commondialog1.Filter = "文本文件(*.txt)*.txt" |
| If commondialog1.FileName <> "" Then |
| strname = commondialog1.FileName |
| strname = App.Path & "emailaddress.txt" |
| Open strname For Output As #1 |
| For i = 0 To lstEmail.ListCount - 1 |
| Print #1, lstEmail.List(i) |
| 本程序在WINDOWS ME、VB6.0中文企业版中运行通过。以上程序稍加修改即可实现提取其他类型文件中的EMAIL地址。 |
