我是一个全新的视觉基础和自我教学的人。我正在工作室2008中构建一个VB(我不得不使用这个版本),它登录到设备,传输登录和密码,然后使用反射传输从.txt文件读取的命令。所有这一切都很好。设备执行命令并输出28种可能的响应中的1种。
我正在使用精选案例来评估答案并采取相应行动。当在会话窗口中看到EXECUTED时,设备会话按预期停止,我的测试数据被设计为所以我得到的第一个响应是“EXECUTED”,奇怪的是我的VB“看到”EXECUTED消息(案例1)但是选择案例响应好像已经看到FAILED(案例2),测试数据的后续行违反了不同的情况(5和6),但响应始终是下一个案例。我试过Case n,case is = n,case“string value”但是我收到了错误。
这是我的代码 - 请注意,我还没有定义所有28个案例,但未定义的案例在我的活动版本中被REM了。我们将非常感激地提出任何想法或建议!

您在第一个"
中缺少双引号Case
。尝试将其更改为:
Case 0 ' "RUNNING"
Result = Dev_Resp(0)
Resp = MsgBox((Dev_Resp(0) & CR & CR & "Continue?"), 17, "Case 0 error")
注意我在"Continue?"
之前添加了双引号。

摆脱With
声明。创建并分配持有者变量并将其与select语句一起使用。这样做将允许您通过在调试器中设置停止点来查看实际传递到select语句的内容。
Dim temp_resp as integer = refl.WaitForStrings(Dev_Resp, "0:4:30")
Select Case temp_resp
'the case statements here.
End Select
答案 2 :(得分:0)
反射WaitForStrings使用从零开始的数组参数,但它返回一个基于1的字符串索引。 Waitforstrings将数组条目零视为第一个有效条目,因此第一个选择案例(Case = 1)对应于数组条目0。
