microsoft access 2010 vba dao记录集findfirst

我有一个名为QB的表，它有一个字段名Item。我正试着用find first和

Dim curDatabase As DAO.Database
  Set curDatabase = CurrentDb
  Set rsQB = curDatabase.OpenRecordset("QB", dbOpenDynaset)

  'This works and equals the value for Item in the first record of the table 
  msgbox (rsQB("Item").Value)

  'Item_No.Value is a string.  The following all do not work:
  rsQB.FindFirst "[Item] = " & Item_No.Value
  rsQB.FindFirst ("[Item] = " & Item_No.Value)
  rsQB.FindFirst "[Item] = '" & Item_No.Value &"'"



  rsQB.Close

---

这个给你什么错误信息

rsQB.FindFirst“[Item]=”&Item_No.Value&“”

这一条会给你什么错误消息<代码>rsQB.FindFirst“[项目]=”&项目编号值&“”
