随时添加删除附件问题？

qq41251299 2008-07-08 05:29:54

下面的命令可以实现添加文件，并记录文件名到text2内，
但我还想能够随时删除text2的内容，随时添加
可是我点了cls按钮后，却不能再添加了？
谁能帮忙给改改，或者有更好的代码和建议？
Private Sub CmdAdd_Click()
With CommonDialog1
.InitDir = App.Path & "\data\0606"
.DialogTitle = "打开"
.CancelError = False
'ToDo: 设置 common dialog 控件的标志和属性
.Filter = "所有文件 (*.*)|*.*"
.ShowOpen
If Len(.FileName) = 0 Then
Exit Sub
End If
End With

Dim i As Long, n As Long
n = Text2.UBound
If n > 4 Then End '最多添加6个附件
For i = 0 To n
If Len(Text2(i).Text) = 0 Then
Exit For
End If
Next '检查有没有空白文件
If i > n Then
Load Text2(i)
Text2(i).Visible = True
Text2(i).Move Text2(i - 1).Left, Text2(i - 1).Top + Text2(i - 1).Height + 90

Load Cmdcls(i)
Cmdcls(i).Visible = True
Cmdcls(i).Move Cmdcls(i - 1).Left, Cmdcls(i - 1).Top + Cmdcls(i - 1).Height + 50
End If
FileNumber = i

End Sub

Private Sub Cmdcls_Click(Index As Integer)
Text2(Index).Text = ""
End Sub

先建立一个按扭,Name=cmdCls Visible=False

再建立一个文件框,Name=Text2 Visible=False



Private Sub CmdAdd_Click()

   With CommonDialog1

        .InitDir = App.Path & "\data\0606"

        .DialogTitle = "打开"

        .CancelError = False

        'ToDo: 设置 common dialog 控件的标志和属性

        .Filter = "所有文件 (*.*) |*.*"

        .ShowOpen

        If Len(.FileName) = 0 Then

            Exit Sub

        End If

    End With

    

    Dim i As Long, n As Long

    n = Text2.UBound

    If n = 5 Then MsgBox "注意，最多添加6个文件"

    If n > 5 Then Exit Sub          '最多添加6个附件



   Load Text2(Text2.Count)

   Load cmdCls(cmdCls.Count)

   Text2(Text2.Count - 1).Text = CommonDialog1.filename

   Text2(Text2.Count - 1).Top = Text2(Text2.Count - 2).Top + Text2(0).Height

   Text2(Text2.Count - 1).Left = Text2(0).Left

   Text2(Text2.Count - 1).Visible = True

  

   cmdCls(cmdCls.Count - 1).Top = cmdCls(cmdCls.Count - 2).Top + cmdCls(0).Height

   cmdCls(cmdCls.Count - 1).Left = cmdCls(0).Left

   cmdCls(cmdCls.Count - 1).Visible = True

  

End Sub



Private Sub Cmdcls_Click(Index As Integer)

   Text2(Index).Text = ""

   For i = Index To Text2.Count - 2

     Text2(i).Text = Text2(i + 1).Text

   Next

   Unload Text2(Text2.Count - 1)

   Unload cmdCls(cmdCls.Count - 1)

   

End Sub
