我怀疑

FindServerConnection\u NoMsg

没有打开连接，因为它以

NoMsg

结尾，所以您没有看到连接未打开的错误。然后，在不知道打开失败的情况下继续使用连接

发布

FindServerConnection\u NoMsg

的代码

---

顺便说一句，你的问题本身应该给你一个线索。它特别指出连接无法使用，并且可能未打开。这应该告诉你从哪里开始查找，至少告诉你应该在你的问题中发布打开连接的代码。

你已经在

TryConnection\u NoMsg

函数（？）中关闭了连接

谢谢大家。我解决了我的问题。这就是我在代码中看到的

两件事：你能把剩下的代码格式化，让它看起来和第一部分一样好吗？另外，代码中的错误发生在哪里？@pbrp:我回滚了您上次的编辑，因为您删除了一些相关的代码（并且完全弄乱了所有代码的格式）。如果你要编辑文章，请学会设置代码格式；“编辑”页面上有可用的帮助。您何时收到此错误？在哪一个动作上？faaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa。将这一点减少到再现错误所需的最小代码量。我相信我在这里遇到了问题。命令未打开。这是我的错误。我认为.commandType=adCmdtext与cmdCommand.ActiveConnection=objConn.CommandText=“query here”之间存在问题.CommandType=adCmdText End With Set rcdReclamation=New ADODB.Recordset With rcdReclamation.ActiveConnection=objConn.CursorType=adOpenDynamic.CursorLocation=adUseClient.LockType=adLockOptimious.Open cmdCommand End With Remove
