先在模塊中聲明和定義函數
Declare Function SHGetPathFromIDList Lib "shell32.dll" _
Alias "SHGetPathFromIDListA" (ByVal pidl As Long, _
ByVal pszPath As String) As Long
Declare Function SHBrowseForFolder Lib "shell32.dll" _
Alias "SHBrowseForFolderA" (lpBrowseInfo As BROWSEINFO) As Long
Type BROWSEINFO
hOwner As Long
pidlRoot As Long
pszDisplayName As String
lpszTitle As String
ulFlags As Long
lpfn As Long
lParam As Long
iImage As Long
End Type
Function GetDirectory(Optional Msg) As String
Dim bInfo As BROWSEINFO
Dim path As String
Dim r As Long, x As Long, pos As Integer
' Root folder = Desktop
bInfo.pidlRoot = 0&
' Title in the dialog
If IsMissing(Msg) Then
bInfo.lpszTitle = "Select a folder."
Else
bInfo.lpszTitle = Msg
End If
' Type of directory to return
bInfo.ulFlags = &H1
' Display the dialog
x = SHBrowseForFolder(bInfo)
' Parse the result
path = Space$(512)
r = SHGetPathFromIDList(ByVal x, ByVal path)
If r Then
pos = InStr(path, Chr$(0))
GetDirectory = Left(path, pos - 1)
Else
GetDirectory = ""
End If
End Function
然後再定義按扭了，最後在標簽上顯示所選路徑
Private Sub Command1_Click()
Label1.Caption = GetDirectory
End Sub
