将VBA转换为VBScript - 不工作但没有错误

Question

我一直在关注有关将VBA转换为VBScript的文章和问题,但我现在卡住了.以下代码仍然适用于VBA(如果我删除Sub例程调用)但它不会作为脚本运行.

该代码打开与SQL Server的连接以检查表以查看该进程是否已在今天运行并将结果加载到Recordset中.如果该字段设置为No然后它打开Excel工作簿并运行宏.它适用于VBA,但是当我运行与脚本相同的代码时,没有任何事情发生(也没有错误).

你能看出问题所在吗？非常感谢.

NB.有两行cmd.CommandText.注释掉的行旨在始终返回No以仅用于测试目的.

您无法在VBScript中实例化外部对象,例如New ADODB.Connection因为没有对外部库的引用.

你不能使用常量像adCmdText无论是.它们将被视为未定义的空变量.

您没有收到任何错误,因为您关闭了它们On Error Resume Next.删除它,你会得到你的错误.

确保所有外部对象实例化都CreateObject像使用Excel一样完成,并将所有外部常量替换为其文字值.
