筛选后导出任意字段内容到EXCEL中，该如何做到

Function 导出数据(tbname As String, frmname As String, subfrmname As String, Qdefname As String, ParamArray A() As Variant)
'功能：导出子窗体数据到Excel中
'参数：tbname--子窗体数据表
'      frmname--主窗体名称
'      subfrmnane--子窗体名称
'      Qdefname--查询名称
'      A()--导出的字段数组
Dim Qdef As QueryDef
Dim strWhere, strSQL As String
Dim i As Long
strWhere = Forms(frmname).Controls(subfrmname).Form.Filter
If strWhere = "" Then strWhere = "True"
strSQL = ""
For i = 0 To UBound(A, 1)
    strSQL = strSQL & A(i) & ","
Next
If strSQL = "" Then
    strSQL = "*"
Else
    strSQL = Left(strSQL, Len(strSQL) - 1)
End If
strSQL = "Select " & strSQL & " FROM " & tbname & " Where " & strWhere
If DCount("*", "MSysObjects", "Type=5 and Name='" & Qdefname & "'") = 0 Then
    Set Qdef = CurrentDb.CreateQueryDef(Qdefname)
    Qdef.SQL = strSQL
End If
Set Qdef = CurrentDb.QueryDefs(Qdefname)
Qdef.SQL = strSQL
Qdef.Close
Set Qdef = Nothing
DoCmd.OutputTo acOutputQuery, Qdefname, acFormatXLS, , True
End Function
