dear wnchan: Dir() doesn't allow the user CHOOSE a path, but return the current path

I think what chuyan needs is a dialog box to Open/Save a File.
In this case, you can use the Common Dialog Control (look in components)

Hope this helps

yup, I think angelIII knows what  I need.  But I'm not sure that if common dialog box works.  Since I only want to let users to choose the directories only, I don't  want to let them input anything by typing.  I just want them to select their desired directory.  Could the common dialog box help?

In this case, not really.
You would need to implement your own dialog box using the drive control and the directory control and some buttons;
or try to find a free dialog box on sites like www.vbcontrol.com or www.vbaccelerator.com
Hope this helps

use the dirlistbox control that is in your toolbox, to see how it works stick a dirlistbox on your form and a textbox and paste this code:

Private Sub Dir1_Change()
    Text1.Text = Dir1.Path
End Sub

To try this example you need to add a textbox , commondialog control and a command button.
add this code in the form and run

Private Sub Command1_Click()
Text1 = CommonDialog1.FileName
End Sub

text1 will contain the path of the file which the user has chosen by clicking the command button.
Hope this will help you.

I'm not sure if I understand correctly what you are looking for, but try this.
Create a new VB Project.
Under the project menu click components. When the box loads, scroll down to find one called Microsoft Common Dialog Control. Check this option and click ok. It's now listed in your toolbox as a small window icon.

Add one to your form.

Once this is done, add the following code to your form's (General) (Declaration) section.

Option Explicit
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

Now add a command button to your form.
Make sure it's named Command1

Copy the following code into the Command1 Click event.
    '     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 un
    '     der the title bar
    ' telling you what to do

    With tBrowseInfo
            .hWndOwner = Me.hWnd ' Owner Form
            .lpszTitle = lstrcat(szTitle, "")
    End With
    lpIDList = SHBrowseForFolder(tBrowseInfo)

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

Run the program and click the button.
You will be prompted with a browse for folder box and you will it will return it's path. Let me know how it works out.
