vb获取启动文件夹路径

答案：Private Const CSIDL_Users_STARTMENU_a = &H7 '当前用户\开始-程序-启动
' 声明API函数
Private Declare Function SHGetPathFromIDList Lib "shell32.dll" Alias "SHGetPathFromIDListA" (ByVal pidl As Long, ByVal pszPath As String) As Long
Private Declare Function SHGetSpecialFolderLocation Lib "shell32.dll" (ByVal hwndOwner As Long, ByVal nFolder As Long, pidl As Long) As Long
Private Function GetSpecialPath(CSIDL As Long) As String
    Dim s As Long
    Dim path As String
    Dim pidl As Long
    '根据指定的文件夹获得pidl
    s = SHGetSpecialFolderLocation(Me.hWnd, CSIDL, pidl)
    If s = NOERROR Then ' 根据r的返回值判断是否有错误发生，如果没有错误就获取文件夹路径
        path = Space$(512)
        s = SHGetPathFromIDList(ByVal pidl, ByVal path)
        GetSpecialPath = Left$(path, InStr(path, Chr$(0)) - 1)
        Exit Function
    End If
    GetSpecialPath = ""
End Function

Private Sub Form_Load()
msgbox GetSpecialPath(CSIDL_Users_STARTMENU_a) & "\"
End Sub
