While working on a Word automation project, I found that VBScript does not offer the necessary error handling required when a COM object (Word object in my case) throws an error/exception. Unfortunately, not all COM objects themselves will output an error message, etc. So in my case, depending on the type of error, I might not know that an error occurred and in any case, the Word object still resided in memory because I could not catch the object error using On Error Resume Next + the Err object (which only works for VBScript's default objects and the VBScript language). Standard Visual Basic and VBA might be better though with their additional error handling options.

So if anyone is using WSH and COM objects or Office objects, I "highly" recommend using JScript over VBScript since JScript's try/catch block will catch the object's error no matter what happens.

That's it, you can no longer be a mod, turn in your badge and gun....
