引擎提示找不到usysPurview对象，涉及usysPurview的有三段代码，高手看一下怎么回事？
(第一段)
Private Function IconLableClick(ByVal intNum As Integer)
Dim PurviewOption As Boolean

DoCmd.OpenForm "frmLogin", , , , , acDialog
Else
Dim rs As ADODB.Recordset, strSQL As String
Set rs = New ADODB.Recordset
strSQL = "select * from usysPurview where (UserID=" & Forms("frmLogin")!UserID & ") and (MenuItem=" & NowWorkSpace & ") and (ItemNumber=" & intNum & ");"
rs.Open strSQL, CurrentProject.Connection, adOpenStatic, adLockReadOnly
If rs.EOF Then
