Path Selection Dialog Box

I was hoping to use the common dialog box for mere path selection (as opposed to actually having to pick a file)

I'd like a "browse for path" dialog box. Are there any common controls that can do this and return only the path name.

Code:

---

'Using the browser dialog box
'make a reference

Option Explicit

Private Const BIF_RETURNONLYFSDIRS = 1
Private Const BIF_DONTGOBELOWDOMAIN = 2
Private Const MAX_PATH = 260

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

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

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

Private 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




Private Sub Form_Load()
'Opens a Browse Folders Dialog Box that displays the
'directories in your computer
Dim lpIDList As Long ' Declare Varibles
Dim sBuffer As String
Dim szTitle As String
Dim tBrowseInfo As BrowseInfo

szTitle = "Hello World. Click on a directory and " & _
"it's path will be displayed in a message box"
' Text to appear in the the gray area under the title bar
' telling you what to do

With tBrowseInfo
.hWndOwner = Me.hWnd ' Owner Form
.lpszTitle = lstrcat(szTitle, "")
.ulFlags = BIF_RETURNONLYFSDIRS + BIF_DONTGOBELOWDOMAIN
End With

lpIDList = SHBrowseForFolder(tBrowseInfo)

If (lpIDList) Then
sBuffer = Space(MAX_PATH)
SHGetPathFromIDList lpIDList, sBuffer
sBuffer = Left(sBuffer, InStr(sBuffer, vbNullChar) - 1)

' <<< Add Your Code Here >>>

MsgBox sBuffer

End If
End Sub

---

This is what I've been using, but I cannot find out how to get the dialog window to start up at a specific directory.

I want to be able to take the user directly to the last selected directory, but instead the dialog starts at the root directory, and the user has to navigate through the directories each time.

Does anybody know how to do this?
