Hi,

I have read numerous articles that mention that VBScript works well with ASP. Knowing that VBScript is a client-side scripting language that is supported only by IE, and that ASP is a server-side scripting language designed for Microsoft's IIS, I am a bit confused by what this means. Could someone please clarify how VBScript works with ASP?

I am not sure how to explain it, but basically ASP is not a language itself. As you probably know it stands for Active Server Pages. These pages may be written in server-side VBScript or server-side Javascript. Server-side vbScript actually came before client-side I beleive, and they are both from the same language specs I beleive except client-side is heavily restricted due to security issues. Javascript is the same way, heavily restricted on the client-side and open on the server-side.

Just did a quick search, haven't read this link but this might be more info: http://www.greenvertigo.net/greenver.../asp/asp01.php

Hi dk01,

Thanks for your response! I think I have a bit better understanding now. I just have one more question:

I have found that there are quite some objects/methods that do not look a thing like VBScript. I'm just totally confused, since I thought this was supposed to be the same thing as VBScript?

For example:

Code:

<%@ Language=VBScript %> 

<HTML> 

<HEAD> 

<TITLE>Example 1</TITLE> 

</HEAD>

<BODY bgcolor=Lime aLink=DarkTurquoise> 

<P> </P> 

<%  Response.Write("Hello, world!")  %> 

</BODY> 

</HTML>

Response.write would not be valid in VBScript. It should be Document.write. Could you please explain this? Thanks!

Response.write XYZ sends a response from the server to the client saying "print XYZ", where XYZ can be a string, variable or return-value function argument.

If you are familiar with PHP, this is much like the echo() function.

Server-side VBS has a much wider range of objects & methods available to it, which is what makes it so much less restrictive.

Consider ASP VBScript a bit more ... relaxed.

Im exploring ASP myself these days ... re-coding www.CanadaHelps.Org with a team of like 7 others

Hi Abhishek,

So are you saying that a whole new set of objects and methods (including Response.write) from ASP are added to VBScript when it becomes used as a server-side language? And these new objects/methods are then converted into the client-side VBScript equivalent?

**Abhishek Reddy** · 11-06-2002, 07:22 AM

I'm assuming you're familiar with the client-server model (?)

Basically, yes to the first part - there are a whole new set of objects and methods available.

One disadvantage with server-side VBScript within ASP is that it is no longer able to interface with objects on the client side. For example, ASP/VBS cannot detect mouse events, like clicks on a button in a webpage.

So you do get a whole new set of objects/methods to play with, but a lot of the client-side flexibility is lost.

As to "conversion to client-side", nope. The code is executed and processed on the server, thus nowhere near the client. Only the resultant data is returned for the user agent to output.

Hi Abhi,

Thanks for the explanation! I understand now.

So when people say that VBScript can be used in ASP, they are referring more to the structure (For...Next, Do...Loop, etc.) rather than the specific objects and methods (like document.write).

**Abhishek Reddy** · 11-07-2002, 09:16 AM

That's pretty much right on the mark.

Both server-side and client-side VBScript have their own unique libraries, but the core libraries are more or less the same.

Thanks!

I'm checking out the forums in your signature. They look great, by the way (very creative use of the vB template, I must say!).

I've already registered and I will drop by and add a few posts soon.

Glad I could be of assistance.
