我需要参考什么吗?我该如何使用:
Dim fso As New FileSystemObject
Dim fld As Folder
Dim ts As TextStream
我收到一个错误,因为它无法识别这些对象。

Answers:
在Excel中,您需要设置对VB脚本运行时库的引用。相关文件通常位于\Windows\System32\scrrun.dll
Microsoft Scripting Runtime
” 旁边的复选框scrrun.dll
将显示在列表框下方如果已启用对VBA对象模型的访问,则也可以直接在代码中完成此操作。
Access可以通过选中复选框启用Trust access to the VBA project object model
在发现文件>选项>信任中心>信任中心设置>宏设置
要添加参考:
Sub Add_Reference()
Application.VBE.ActiveVBProject.References.AddFromFile "C:\Windows\System32\scrrun.dll"
'Add a reference
End Sub
删除参考:
Sub Remove_Reference()
Dim oReference As Object
Set oReference = Application.VBE.ActiveVBProject.References.Item("Scripting")
Application.VBE.ActiveVBProject.References.Remove oReference
'Remove a reference
End Sub
在excel 2013中,对象创建字符串为:
Dim fso
Set fso = CreateObject("Scripting.FileSystemObject")
而不是上面答案中的代码:
Dim fs,fname
Set fs=Server.CreateObject("Scripting.FileSystemObject")
Dim fso As Object
这些家伙提供了有关如何使用文件系统对象http://www.w3schools.com/asp/asp_ref_filesystem.asp的出色示例。
<%
dim fs,fname
set fs=Server.CreateObject("Scripting.FileSystemObject")
set fname=fs.CreateTextFile("c:\test.txt",true)
fname.WriteLine("Hello World!")
fname.Close
set fname=nothing
set fs=nothing
%>
添加参考之后,我不得不使用
Dim fso As New Scripting.FileSystemObject
如上所述导入脚本运行时后,您必须进行一些稍微的修改才能使其在Excel 2010(我的版本)中正常工作。在以下代码中,我还添加了用于用户选择文件的代码。
Dim intChoice As Integer
Dim strPath As String
' Select one file
Application.FileDialog(msoFileDialogOpen).AllowMultiSelect = False
' Show the selection window
intChoice = Application.FileDialog(msoFileDialogOpen).Show
' Get back the user option
If intChoice <> 0 Then
strPath = Application.FileDialog(msoFileDialogOpen).SelectedItems(1)
Else
Exit Sub
End If
Dim FSO As New Scripting.FileSystemObject
Dim fsoStream As Scripting.TextStream
Dim strLine As String
Set fsoStream = FSO.OpenTextFile(strPath)
Do Until fsoStream.AtEndOfStream = True
strLine = fsoStream.ReadLine
' ... do your work ...
Loop
fsoStream.Close
Set FSO = Nothing
希望对您有所帮助!
