VB6.0 如何调用存储过程，返回结果集问题？

对于VB6.0这个软件，估计对于现在很多程序员来说，都不知道啥软件来了，但本人还在摸，

    If rs.BOF And rs.EOF Then
        MsgBox "There is no master FR connect setting, please contact IT."
        Exit Sub
    Else
        frConnectStr = rs("DESCRIPTION")
    End If
    
    
    If frCn.State = adStateOpen Then
      frCn.Close
      Set frCn = Nothing
    End If
    
    frCn.CursorLocation = adUseServer 'adUseClient 'adUseServer
    frCn.IsolationLevel = adXactReadCommitted
    frCn.CommandTimeout = 1800
    frCn.Open frConnectStr

'    Dim cmd As ADODB.Command
'    Set cmd = New ADODB.Command
'    cmd.CommandText = "dbo.FR_GEN_DATA_FOR_AGPO"
'    cmd.CommandType = adCmdStoredProc
'    cmd.ActiveConnection = frCn
'    cmd.CommandTimeout = 300
'    With cmd.Parameters
'        .Append cmd.CreateParameter("@JOSTR", adVarChar, adParamInput, 4000, "20G04502DE01,20G07345GB01,")
'        .Append cmd.CreateParameter("@Character", adVarChar, adParamInput, 1, "C")
'        .Append cmd.CreateParameter("@DayPeriod", adInteger, adParamInput, , 7)
'   End With
'   Set rsFr = cmd.Execute
'    Debug.Print cmd.State


    sql = "exec dbo.FR_GEN_DATA_FOR_AGPO '20G04502DE01,20G07345GB01,', 'C',7"
    Set rsFr = frCn.Execute(sql)
    
   
   Debug.Print rsFr.State
   If rsFr.State = 1 Then
    Debug.Print rsFr.RecordCount
    If rsFr.BOF And rsFr.EOF Then
        MsgBox "There is no mapping data in FR."
    Else
        Do While Not rsFr.EOF
            Debug.Print rsFr(0)
        
         rsFr.MoveNext
        Loop
    End If
    'Get JO, by G or C
    
   End If

记得存储过程，要补上一个 SET NOCOUNT ON， 原理不详~~~囧
