'下面的这些你放在模块里
Public Type BrowseInfo
hWndOwner As Long
pIDLRoot As Long
pszDisplayName As Long
lpszTitle As Long
ulFlags As Long
lpfnCallback As Long
lParam As Long
iImage As Long
End Type

Public Const MAX_PATH = 260

Public Declare Sub CoTaskMemFree Lib "ole32.dll" (ByVal hMem As Long)

Public Declare Function lstrcat Lib "kernel32" Alias "lstrcatA" (ByVal lpString1 As String, ByVal lpString2 As String) As Long

Public Declare Function SHBrowseForFolder Lib "shell32" (lpbi As BrowseInfo) As Long

Public Declare Function SHGetPathFromIDList Lib "shell32" (ByVal pidList As Long, ByVal lpBuffer As String) As Long

Public Function BrowseForFolder(hWndOwner As Long, sPrompt As String) As String

Dim iNull As Integer
Dim lpIDList As Long
Dim lResult As Long
Dim sPath As String
Dim udtBI As BrowseInfo

With udtBI
.hWndOwner = hWndOwner
.lpszTitle = lstrcat(sPrompt, "")
.ulFlags = BIF_RETURNONLYFSDIRS
End With

lpIDList = SHBrowseForFolder(udtBI)

If lpIDList Then
sPath = String$(MAX_PATH, 0)
lResult = SHGetPathFromIDList(lpIDList, sPath)
Call CoTaskMemFree(lpIDList)
iNull = InStr(sPath, vbNullChar)

If iNull Then
sPath = Left$(sPath, iNull - 1)
End If

End If

BrowseForFolder = sPath

End Function

这些你就可以放在过程序：
sdirectoryname = BrowseForFolder(Me.hwnd, "请选择目录")
Text1.Text = sdirectoryname

你要的是不是这样呢。这是我写程序时收集的，具体地址我没有记下来
拿出来和多在一起分享一下。
