vb中在界面上如何设计使输出路径可在盘符下文件夹中可选，还可以建立新文件夹
'=======================================================================
'以下部分代码放在模块中
Option Explicit
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 BIF_RETURNONLYFSDIRS = 1
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 ForFolder(hwndOwner As Long, sPrompt As String) As String
'declare variables to be used
Dim iNull As Integer
Dim lpIDList As Long
Dim lResult As Long
Dim sPath As String
Dim udtBI As BrowseInfo
'initialise variables
With udtBI
.hwndOwner = hwndOwner
.lpszTitle = lstrcat(sPrompt, "")
.ulFlags = BIF_RETURNONLYFSDIRS
End With
'Call the browse for folder API
lpIDList = SHBrowseForFolder(udtBI)
'get the resulting string path
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
'If cancel was pressed, sPath = ""
ForFolder = sPath
End Function
'在窗体上放一个按钮控件，一个文本框控件，输入以下代码：
Private Sub Command1_Click()
pa2 = ForFolder(hWnd, "请选择目录")
If Right(pa2, 1) <> "\" Then pa2 = pa2 + "\"
Text1.Text = pa2
End Sub
太感谢了，不过我试着弹出几个对话框，不能正常
Public Const BIF_RETURNONLYFSDIRS = 1
Public Const MAX_PATH = 260
这段好像不对
注意上面的代码要放到模块里面啊~！
能给我一段代码吗，我主要是可以通过自己选择输出的目录，但是这个输出的TXT是新建的
