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。一 设计界面 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：
二 输入源程序Dim X, Y, St1, St2, tmpY As Integer'提取EMAIL地址子程序Private Sub StripEmail(FilePath As String)Dim tmpEmail1, tmpEmail2 As StringOpen FilePath For Input As #1Do Until EOF(1)On Error Resume NextInput #1, tmpEmail1For X = 1 To Len(tmpEmail1)tmpEmail2 = Mid(tmpEmail1, X, 7)'查找EMAIL标志If tmpEmail2 = "mailto:" ThenSt1 = XtmpY = X + 1For Y = 1 To Len(tmpEmail1)tmpEmail2 = Mid(tmpEmail1, tmpY, 1)If tmpEmail2 = Chr(34) Or tmpEmail2 = "?" ThenSt2 = tmpYtmpEmail2 = Mid(tmpEmail1, St1 + 7, ((St2 - St1) - 7))If (Left(tmpEmail2, 2) <> "//") And (Left(tmpEmail2, 1) <> " ") ThenlstEmail.AddItem tmpEmail2Exit ForEnd IfEnd IftmpY = tmpY + 1Next YEnd IfNext XLoopClose #1End SubPrivate Sub Command1_Click()Dim fs As New FileSystemObject ' 建立 FileSystemObjectDim fd As Folder ' 定义 Folder 对象Dim sfd As FolderSet fd = fs.GetFolder(Text1)Command1.Enabled = FalseScreen.MousePointer = vbHourglassFindFile fd, "*.htm" 'Text1.TextCommand1.Enabled = TrueScreen.MousePointer = vbDefaultEnd SubSub FindFile(fd As Folder, FileName As String)Dim sfd As Folder, f As File' Part I查找该文件夹的所有文件For Each f In fd.FilesIf UCase(f.Name) Like UCase(FileName) ThenLabel2 = f.PathStripEmail (f.Path)lblEmail = "已查找到的地址数为: " & lstEmail.ListCountEnd IfDoEventsNext' Part II循环查找所有子文件夹For Each sfd In fd.SubFoldersFindFile sfd, FileName ' 循环查找NextEnd Sub Private Sub Command2_Click()'去掉重复的EMAIL地址For i = 0 To lstEmail.ListCount - 1For X = 0 To lstEmail.ListCount - 1If i = X Then GoTo NextxIf LCase(lstEmail.List(X)) = LCase(lstEmail.List(i)) ThenOn Error Resume NextlstEmail.RemoveItem XEnd IfNextx:Next XNext ilblEmail = "共有" & lstEmail.ListCount & "个地址"End Sub'保存Private Sub Command3_Click()'设置文件名Dim strname As Stringcommondialog1.Filter = "文本文件(*.txt)*.txt"commondialog1.ShowSaveIf commondialog1.FileName <> "" Thenstrname = commondialog1.FileNameElsestrname = App.Path & "\emailaddress.txt"End If'保存文件Open strname For Output As #1On Error Resume NextFor i = 0 To lstEmail.ListCount - 1Print #1, lstEmail.List(i)NextClose #1End Sub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。
