回答（1）：

VB可以使用FileListBox 控件来获取指定文件夹内的所有文件名。

FileListBox 控件，在运行时，在 Path 属性指定的目录中，FileListBox 控件将文件定位并列举出来。该控件用来显示所选择文件类型的文件列表。例如，可以在应用程序中创建对话框，通过它选择一个文件或者一组文件。

以下是组合使用DriveListBox 、控件DirListBox 控件和FileListBox 控件来获取硬盘下任何一个文件夹内的文件名。

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

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

Private Sub File1_Click()
    Dim i As Long
    Debug.Print "目录夹内存在" & File1.ListCount & "个文件。"
End Sub

已经完成，请留下E _ M _ A _I L或者用下面内容

1.建立一个窗体
2.放置一个文本框，用于输入索引路径，文本框命名为txtDirPath
3.放置一个按钮，用于开始索引，按钮命名为cmdSearch
4.放置一个Label，用于显示索引进度，命名为lblState
5.放置一个Command按钮，用于保存索引结果，命名为cmdSave

程序代码如下：
Dim searchingPath As String

Dim pl As Long
Dim finalOut As String
Dim c As Long

Private Sub cmdSave_Click()
Open "c:\out.txt" For Output As #1
Print #1, finalOut
Close #1
lblState.Caption = "保存完成! 已经写入到C:\Out.txt": DoEvents
End Sub

Private Sub cmdSearch_Click()
c = 0
If Right(txtDirPath.Text, 1) <> "\" Then txtDirPath.Text = txtDirPath.Text + "\"
pl = Len(txtDirPath.Text)
SearchFile txtDirPath.Text
End Sub

Private Sub Form_Load()
Me.Show
txtDirPath.SetFocus
txtDirPath.SelStart = Len(txtDirPath.Text)
End Sub

Private Sub txtDirPath_KeyPress(KeyAscii As Integer)
If KeyAscii = 13 Then cmdSearch_Click
End Sub

Sub SearchFile(strPath As String)
On Error Resume Next
Dim strName As String
Dim dir_i() As String
Dim i As Long, idir As Long
Dim showStr As String

If Right(strPath, 1) <> "\" Then strPath = strPath + "\"
strName = Dir(strPath, vbDirectory Or vbHidden Or vbNormal Or vbReadOnly)

Do While Len(strName) > 0
If strName <> "." And strName <> ".." Then
If (GetAttr(strPath & strName) And vbDirectory) = vbDirectory Then
idir = idir + 1
ReDim Preserve dir_i(idir) As String
dir_i(idir - 1) = strName
Else
c = c + 1
showStr = Replace(Mid(strPath, pl + 1), "\", "><")
finalOut = finalOut + "<" + Left(showStr, Len(showStr) - 1) + strName + vbCrLf
End If
End If
strName = Dir

If searchingPath <> strPath Then
lblState.Caption = "索引数: " & CStr(c) & "，搜索目录: " & strPath
searchingPath = strPath
DoEvents
End If
Loop

For i = 0 To idir - 1
Call SearchFile(strPath + dir_i(i))
Next i

Erase dir_i

lblState.Caption = "搜索完成，总计文件数: " & CStr(c)
End Sub
