本文实例讲述了VB打开与保存txt文件的方法。分享给大家供大家参考。具体如下：

Private Sub cmdsave_Click() Dim filelocation As String ' loads save as box commondialog1.ShowSave filelocation = commondialog1.FileName ' append saves over file if it assists Open filelocation For Append As #1 Print #1, text1.text Close #1 End Sub Private Sub cmdopen_Click() Dim filelocation As String ' show open box commondialog1.ShowOpen filelocation = commondialog1.FileName ' input files into text1.text Open filelocation For Input As #1 Do Until EOF(1) Input #1, Data text1.text = text1.text + Data + vbNewLine EOF (1) Loop Close #1 End Sub

希望本文所述对大家的VB程序设计有所帮助。
