Converting VBA to VBScript - Not working but no error

问题

I've been following articles and questions about converting VBA to VBScript but I'm now stuck. The following code still works in VBA (if I remove the Sub routine call) but it won't run as a script.

The code opens a connection to SQL Server to check a table to see if the process has already run today and loads the result into a Recordset. If the field is set to No then it opens up an Excel workbook and runs a macro. It works in VBA but when I run the same code as a script nothing happens (no errors either).

Can you see what the problem is? Thanks very much.

NB. There are two lines for cmd.CommandText. The commented out line is designed to always return No for testing purposes only.

You can't instantiate external objects in VBScript with e.g. New ADODB.Connection because there are no references to external libraries.

You can't use constants like adCmdText either. They will be treated as undefined empty variables.

You don't get any errors because you shut them up with On Error Resume Next. Remove that and you will get your errors.

Make sure all external object instantiation is done with CreateObject like you are doing for Excel, and replace all external constants with their literal values.
