定位文件夹的控件是哪个，不要DirListBox

[7kxa]

想找那个系统自带的定位文件夹的控件，就像定位文件用Common Dialog就是调用系统自带的文件浏览器。

[liul17]

只能自已编，可用 Filesystem对象

用SHBrowseForFolder及回调函数：

模块：

Private Const BIF_STATUSTEXT = &H4&
Private Const BIF_RETURNONLYFSDIRS = 1
Private Const BIF_DONTGOBELOWDOMAIN = 2

Private Const WM_USER = &H400

SHGetPathFromIDList lpIDList, sBuffer
sBuffer = Left(sBuffer, InStr(sBuffer, vbNullChar) - 1)

End If

End Function

Private Function BrowseCallbackProc(ByVal hWnd As Long, ByVal uMsg As Long, ByVal lp As Long, ByVal pData As Long) As Long

Dim lpIDList As Long
Dim ret As Long
Dim sBuffer As String

On Error Resume Next 'Sugested by MS to prevent an error from

Select Case uMsg

Case BFFM_INITIALIZED

Call SendMessage(hWnd, BFFM_SETSTATUSTEXT, 0, sBuffer)
End If

End Select

BrowseCallbackProc = 0

End Function

Private Function GetAddressofFunction(add As Long) As Long
GetAddressofFunction = add
End Function

窗体中：

Private Sub Command1_Click()
getdir = BrowseForFolder(Me, "选择路径", _默认的路径)
End Sub
