Private Const SW_SHOWMINIMIZED = 2
Private Const SW_SHOWMINNOACTIVE = 7
Private Const SW_SHOWNA = 8
Private Const SW_SHOWNOACTIVATE = 4
Private Const SW_SHOWNORMAL = 1

Private Const ERROR_FILE_NOT_FOUND = 2&
Private Const ERROR_PATH_NOT_FOUND = 3&
Private Const ERROR_BAD_FORMAT = 11&
Private Const SE_ERR_ACCESSDENIED = 5            '  access denied
Private Const SE_ERR_ASSOCINCOMPLETE = 27
Private Const SE_ERR_DDEBUSY = 30
Private Const SE_ERR_DDEFAIL = 29
Private Const SE_ERR_DDETIMEOUT = 28
