文件知识大汇聚

我们每天点来点去，在C、D、E、F盘中来回的穿越。好像在找什么东西似的。开始以为文件很神秘，不知道奇怪的文件从何方而来，见证奇迹的时刻到来了。

对驱动、目录和文件列表框编写的代码如下。

Private Sub Command1_Click(Index As Integer)
Select Case Index
Case 0
File1.Pattern = "*.*"
Case 1
File1.Pattern = "*.txt"
Case 2
File1.Pattern = "*.jpg;*.bmp;*.tif"
Case 3
File1.Pattern = "*.mp3;*.avi;*.wav;*.dat"
End Select
End Sub

Private Sub Dir1_Change()
File1.Path = Dir1.Path
End Sub

Private Sub Drive1_Change()
Dir1.Path = Drive1.Drive
End Sub

Private Sub Form_Load()
Dir1.Path = "c:\windows"
End Sub

显示文件路径名

Private Sub Dir1_Change()
File1.Path = Dir1.Path
Label1.Caption = Dir1.Path
End Sub

Private Sub Drive1_Change()
Dir1.Path = Drive1.Drive
Label1.Caption = Drive1.Drive
End Sub

Private Sub File1_Click()
If Right(Dir1.Path,1) = "\" Then
Label1.Caption = Dir1.Path & File1.FileName
Else
Label1.Caption = Dir1.Path & "\" & File1.FileName
End If
End Sub

Private Sub Form_Load()
Dir1.Path = Drive1.Drive
File1.FileName = Dir1.Path
End Sub

调用系统文件

Private Sub Command1_Click(Index As Integer)
Dim x
Select Case Index
Case 0
x =Shell("D:\qq\QQProtect\Bin\QQProtect.exe",1)
Case 1
x = Shell("D:\qq\QQProtect\Bin\QQProtect.exe",3)
Case 2
x = Shell("D:\qq\QQProtect\Bin\QQProtect.exe",3)
Case 3
x = Shell("D:\qq\QQProtect\Bin\QQProtect.exe",1)
End Select
End Sub

Private Sub Command1_Click()
Dim killedfile As String,xuanzhe As String
Dim x
If Right(Dir1.Path,1) = "\" Then
xuanzhe = Dir1.Path & File1.FileName
Else
xuanzhe = Dir1.Path & "\" & File1.FileName
End If
killedfile = xuanzhe
x = MsgBox("你确认你删除文件吗？",35,"确认框")
If x = 6 Then
Kill killedfile
MsgBox "确认已删除！"
End If
End Sub

Private Sub Command2_Click()
End
End Sub

Private Sub Dir1_Change()
File1.Path = Dir1.Path
End Sub

Private Sub Drive1_Change()
Dir1.Path = Drive1.Drive
End Sub

文件的复制

Private Sub Command1_Click()
Dim yuanfile As String,mufile As String
If Right(Dir1.Path,1) = "\" Then
yuanfile = Dir1.Path & File1.Path
Else
yuanfile = Dir1.Path & "\" & File1.Path
End If
mufile = InputBox("请输入要复制的目的文件","请输入")
If mufile <> "" Then
FileCopy yuanfile,mufile
MsgBox "复制成功"
End If

End Sub

Private Sub Dir1_Change()
File1.Path = Dir1.Path
End Sub

Private Sub Drive1_Change() Dir1.Path = Drive1.Drive End Sub
