Top 3 missing VBScript features

Why oh why am I stuck developing ASP/VBScript - that language is so crippled I can’t believe it. Every time I try to do something Right™ I bang my head against silly limitations of the language. At the moment I am really really missing

1. Proper including of external files. Server Side Includes and/or Server.Execute doesn’t quite cut it when the scripting language doesn’t have namespaces or any way of checking if a certain class already exists. If you have defined one name somewhere in a file, the language provides you with no way to avoid including that file a second time elsewhere in your code, which results in a compilation error.
2. Proper objects. Currently there is no inheritance, no typechecking of objects, no polymorphism. Objects are nothing more than a way to group functions. Actually they might be the a way to provide namespaces if it was possible to avoid including files more than once.
3. Crappy error handling. I want exceptions. Just telling the scripting engine to continue to next line if an error occurs doesn’t cut it.

Hm, I wonder if it is possible to migrate seamlessly to a .NET solution without having to rewrite the entire codebase at once.

Comments and Trackbacks

Judging by the features you miss, VBScript probably isn't the tool you need. ASP.NET written in C# might be more up your alley; as for migrating seamlessly from "classic" ASP, I don't know. Good luck :)

Actually, a complete C# rewrite (very nice language, BTW) would be quite an undertaking, if you want to take full advantage of the C#'s features (which is, like, the whole point of the rewrite effort).

Yeah, it is a matter of choosing the right tool for the job. Unfortunatly in this case, the tool has been chosen and I am not sure it is feasible to rechoose after a couple of years of development.

C# is probably what I would be aiming for (from what I have seen and read it looks real nice), however I am not certain it is possible to run both classic ASP and .NET on the same web application without asking for major problems. And no, I don't (at the moment) have a good way of testing it.
