What is sadscript? Can I use it in vb.net? Why hasn't anyone I have asked heard of it? - vb.net

The title is my question.
Basically, I have heard people speak of it before, I understand it to have something to do with vb6, and I know it lets the user code for the application, but I am unable to determine if it is a separate library or built into vb, and I cannot find documentation for it anywhere.
Thanks for the help!

Sadscript appears to be a scripting language for a mmorg engine called Eclipse (not the IDE called Eclipse). As far as I can tell, the only connection to Visual Basic is that sadscript has a very similar syntax to VB6, so it will be easy to learn if you know VB (and vice versa).

Introduction
Sadscript is a variant of VB6 used for scripting. It isn't natively part of VB6. I've seen it used as part of VB6, rumors of it's use with python, and heard that it can be used for VB.NET.
Acceptance
It's been used in MMORPG engines like Elysium Diamond, PlayerWorlds, and more. It's most prominent livliness is through the MMORPG engine known as Eclipse. It's said to be an easy scripting language and there are rumors that some colleges teach this scripting language. Because of how VB6 is, scripting alternatives for VB6 are few and far between (Also see VB6 & Lua ).
Obtain
The "SadScript Engine" (for lack of better words) itself is quite difficult to find. There appears to be no central repository, and only remants of links to it's engine. I managed to find a link to the SadScript 3 Engine & tutorial for MirageSource MMORPG engine.

Unmanaged language or library to write shell extension?

I need to write a cascading shell extension à la 7Zip. It appears that only the .Net 4 framework supports this, but even in March 2012, MS still advises against using a managed language for this purpose.
So what unmanaged languages are available to write shell extensions for Windows (XP, Vista, 7)?
I read that writing a COM DLL is not easy even for seasoned C++ developpers, so it's probably a dead-end for non-pros. VB6 has been deadware for a decade. I looked at PureBasic and PowerBasic but they don't seem good candidates either.
So is there simply no reasonably easy language to write a cascading shell extension?
As a work-around, is there a library that I could call from VB.Net that would handle the hard part?
Thank you.
There is not a lot you can do if you're not willing to go into the unmanaged world. There is a series of articles on codeproject. This is the first of such articles. They helped me quite a bit. It is written in unmanaged c++ using visual studios ATL project which takes care of some other classes that you would otherwise have to deal with.
COM objects may not be the easiest thing to understand but once they're working they are fairly solid. If anything just treat it as a learning experience.

Can VB.NET be used as a game engine?

I know VB.NET, and I've been planning on creating a simple 2d game engine. I got no problems with creating such engine and running the actual game. However, I've been told that VB.NET might not be the best choice for "working too much with graphics". I'd like to know if that's true. Can VB.NET truly not manage efficiently loads of graphics simultaneously on the screen? If no, what kind of software am I supposed to use for creating this engine?
I have found that people generally view VB.NET as a subpar language, and mostly associate it with Visual Basic 6.0 (or earlier).
In the .NET world, VB.NET is a first class citizen that simply has a verbose syntax. It's particularly because of the verbosity that I would probably choose C#, if not going with C++.
Still, you can use VB.NET to work with whatever drawing libraries that you want, and you can even use it with XNA and Managed DirectX. It can even be linked against unmanaged libraries as long as you are willing to do to the required interop.
As for managing the graphics on the screen efficiently, it really depends on how well you do it, and how much you want done. If someone can do it well in C#, then you can do it well in VB.NET with the exception of unsafe code. It's too general to say either way given the vague "simple 2D game engine" description, but chances are it is more than possible.
These days, managed code is quickly catching up to unmanaged code, and while it's not quite perfect, it is really impressively good.
It's not the language you need to consider as much as the Framework.
Suggest you look at XNA:
Your First Game - XNA Game Studio in 2D (step-by-step tutorial)
Also, DirectX:
DirectX Developer Center
Learn DirectX
VB.NET Already supports XNA including on Windows Phone 7. So if you are looking to develop games and if you language of choice is VB + XNA you are all set to go.
Take a look at the official announcement: http://blogs.msdn.com/b/lisa/archive/2011/03/28/xna-is-coming-to-visual-basic.aspx
Visual Basic's primary use is for Win 32 Apps with a standard GUI. If you are planning on building a game I definitely recommend C++. It has faster execution speed and better libraries for game development. Visual Basic will not deliver as good of performance of C++ would give you. IMO It would be better for you and the user.
I don't know much of the graphics issues in vb but as far as i have heard you can't create games for xbox using vb.net, it only supports PC.
XNA game studio can be used for game development. Although it is supposed for c#, you can find how to use it with vb in here...
http://www.alanphipps.com/VisualBasicdotNET-XNA.html
If you are still relatively new to programming then C++ is more than likely to make you quit early.
Don't aim at C++ until you have at learned C#.
C++ is a great and diverse language but definitely not friendly grounds for anyone who hasn't been programming for a long time. This is ESPECIALLY considering if your first language is one such a VB.
To Answer the Topic?
Yes vb.net can make a game, arcade,FPS,RPG,MMO or what ever you what within your ability to code. if you wanna learn some find playing with open source engines to get the feel helps. so try looking up some and give that a go.
my comment is at the person above's comment,
Visual Basic can do alot, and we find out new stuff all the time.
i seen vb6 game engines work well, graphical and feature wise.
wile visual basic is more down to earth for writing, C++ isnt ik its not, ive tried it.
but VB i can pick up easyr.
my experience ?? 2007 to present day, ive work with vb6 mmo game engine source codes,
Mirage,Elysium,Eclipse,EA,EFF
ive also tried using irrlect engine years back.
for a beginner should learn VB.net or C# .
C++ is to complex.

VB6 Parser/Lexer/Scripter

I've got a game in VB6 and it works great and all, but I have been toying with the idea of creating a scripting engine. Ii'm thinking I'd like VB6 to read in flat text script files for me and then lex/parse/execute them.
I have good programming experience, and I've built a simple C compiler, as well as a LOGO emulator before.
My question is:
Are there any tools that I can use, like Lexx/Yakk/Bison to help me? How should I approach this problem in regards to lexing, parsing, and feeding the commands back to VB6 so I can handle them? Is this idea a BAD IDEA in the sense that there are too many obstacles in the way (For example, building minesweeper in assembly, though not impossible, is very difficult, and a bad idea.)?
Use the Microsoft® Windows® Script Control because it is easy to integrate into existing VB6 applications. The control supports VBScript, JScript, or any other "Active Script" implementation.
I have used the Windows Script Control in four projects and it works extremely well. Very easy to integrate. I wish Microsoft would have given us a replacement in .NET, and made it as easy to use. (I understand the control is not needed in .NET, but having the ability to simply create an object that handles everything is nice.)
Windows Script Control
The Microsoft® Windows® Script Control
is an ActiveX® control that provides
developers with an easy way to make
their applications scriptable. This,
in turn, enables users to extend
application functionality through
scripts, much as they do with macros
today.

Unless you're doing it for your own instruction, you may want to try using Lua: VB6 - Lua Integration
If you're willing to use VBScript rather than VB6 you might be able to just use the MSScriptControl to run the commands rather than creating your own. Here's an article discussing using it from a .Net app, though it's an ActiveX control so should give you quite a bit of flexibility.
The control can be downloaded from here.
I've actually seen some quite reasonable implementations of compilers/interpreters in VB6[1] - It's not the language I would choose (few functional features, insufficent static type system), but with experience, you can outweigh these drawbacks and be quite productive - So why not.
You can use the GOLD parser generator that supports VB6 as a start.
[1]: Somewhere on PSC or in this download repository I think ...
Note that there is the MSScriptControl too.
There also appears to be an additonal alternative for VB6:
SadScript is an variant of VB6 most prominently used for VB6 as an scripting engine in MMORPGS .

Is there any Subtext IDE or equivalent Example-driven Visual Programming Language/Interface published on the Internet?

I'm really excited about this new and experimental language named Subtext. But it's author haven't released nothing about it besides some papers and videos. Should I clone it? There are similar alternatives?
UPDATE I'm looking for an example-driven VPL, not just a VPL.
As Edwards' says in his related work section, the Self programming language is very similar. It shares subtext's emphsis on directness, uniformity, and liveness, but doesn't emphasize a tabular format (Schematic tables).
A lot of of work went into the Solaris version:
http://research.sun.com/self/papers/papers.html
seems there's a Mac & linux version, not sure how mature it is:
http://selflanguage.org/
Here's a video demo'ing Self, where they emphasize directness, uniformity, and liveness:
http://www.smalltalk.org.br/movies/
When you say "any VPL", do you mean none at all, or not a run-of-the-mill one? From the wording of the title question, I'll assume the latter. Here're a couple with some serious programming theory behind them:
Morphic is/was a/the UI piece of Self, and is now ported to Squeak:
http://wiki.squeak.org/squeak/2139
Prograph was a way-cool system, but I don't know of an available version.
A bit further out there is Kahn's Toontalk, based on Pictorial Janus:
http://www.toontalk.com/
I am sure you are aware of VPL On Wikipedia that lists many different VPL languages. You have not supplied information on what you are trying to achieve but another site is Synopsis. This is a commercial product.
From their website:
Synopsis is a completely visual RAD tool for Windows that frees you from having to write textual code and learning unnecesary programming details. With Synopsis you can concentrate on creating software instead of wrestling with mundane and complex low-level development tasks.
The image below shows how this application looks:
(source: codemorphis.com)
Granted my knowledge on this subject is limited and I do follow this to see if something really powerful can be created. I did see a project on CodeProject or CodePlex that was written in C# that allowed VPL but I cant find that URL.
If I ever do find that application I will edit this post!
You haven't provided more information about features you expect from such a VPL environment, but I think that "Tersus" could be interesting thing to look at. There're many VPLs, but mainly they're targeted as educational tools or addition to particular technologies (i.e VPL for Microsoft Robotics Studio) to simplify common tasks programming. The "Tersus" is full blown application development platform. It's open source and free to download for many OSes.

Coherence — The Director’s Cut
The Coherence home page is up at http://coherence-lang.org. The submitted version of the paper is there, with a new intro and a surprise ending.
Coherence claims to be an experimental programming language, a continuation of Subtext using other means.
Intentional shipped, but they are still kind of alpha, with limited distribution and testing. You can make example driven DSLs, but I don't know if the environment itself works that way.

Has Lua a future as a general-purpose scripting language?

As already discussed in "Lua as a general-purpose scripting language?" Lua currently probably isn't the best scripting language for the desktop environment.
But what do you think about the future? Will Lua get so popular that there will soon be enough libraries to be able to use it like Python, Ruby or something similar?
Or will it simply stay in it's WoW niche and that's it?
I think it has a great future, a lot of projects are starting to adopt it for it's simplicity and usefulness.
Example: Awesome WM (Window Manager)
The project recently released version 3, incorporating a new configuration system completely written in Lua. Allowing you to literally write your configuration file as a program, loops, booleans, data structures.
Personally I love the syntax and the flexibility of such a system, I think it has great potential.
I wouldn't be surprised if it became more popular in the future.

I suppose the answer starts with 'It depends how you want to use it...'.
If you're writing the common business app (fetch the data from the database, display the data in a web page or window, save the data to the database), Lua already has what you need.
The Kepler Project contains goodies for web development. Check out their modules to see some of the available libraries - there's network, MVC, DBMS access, XML, zip, WSAPI, docs...
As an example web app, check out Sputnik.
For desktop UI, there's wxLua - Lua hooks for wxWidgets.
ORM is conspicuously missing but that didn't stop people from developing in other languages before ORM was available.
If you're looking for specialized libraries - scientific, multimedia , security - don't count Lua out before you check LuaForge.
When it comes down to it, there's nothing in Lua's design that prevents general purpose use. It just happens to be small, fast, and easy to embed... so people do.
Uh? I would say instead WoW is a niche in the Lua ecosystem... The world of Lua doesn't revolve around WoW, there are lot of applications, some big like Adobe Lightroom (to take a non game), using Lua.
Lua is initially a scripting language, in the initial sense, ie. made to be embedded in an application to script it. But it is also designed as an extensible language, so we will see progressively more and more bindings of various libraries for various purposes.
But you will never get an official big distribution with batteries included, like Python or Perl, because it is just not the philosophy of the authors.
Which doesn't prevent other people to make distributions including lot of features out of the box (for Windows, particularly, where it is difficult to build the softwares).
Lot of people already use it for general system-level scripting, desktop applications, and such anyway.
There are more and more libraries for Lua.
If you are a Windows user, have look at Lua for Windows. It comes with "batteries included" (wxLua, LuaCURL, LuaUnit, getopt, LuaXML, LPeg...).
Very usefull!
It's 2017, 9 years after this question was first asked, and lua is now being heavily used in the field of machine learning due to the Torch library.
I really like it as an embedded language. It's small, very easy to use and embed and mostly does what I need right out of the box. It's also similar enough to most languages that it has never really been an issue for me. I also like how easy it is to redefine and add base functions and keywords to the language to suit whatever needs my application has.
I have used it in the WoW area but I've also found it useful as a generic scripting language for a number of different applications I've worked on, including as a type of database trigger. I like Ruby and Python and other more full-featured scripting languages but they're not nearly as convenient for embedding in small applications to give users more options for customizing their environments.
being comfortable as a shell language has nothing to do with being a great general purpose language.
i, for one, don't use it embedded in other applications; i write my applications in Lua, and anything 'extra' is a special-purpose library, either in Lua or in C.
Also, being 'popular' isn't so important. in the Lua-users list periodically someone appears that says "Lua won't be popular unless it does X!", and the usual answer is either: "great!, write it!", or "already discussed and rejected".
I think the great feature of Lua is, that it is very easily extensible. It is very easy to add the Lua interpreter to a program of your own (e.g. one written in C, C++ or Obj-C) and with just a few lines of code, you can give Lua access to any system resource you can think of. E.g. Lua offers no function to do xxx. Write one and make it available to Lua. But it's also possible the other way round. Write your own Lua extension in a language of your choice (one that is compilable), compile it into a native library, load the library within Lua and you can use the function.
That said, Lua might not be the best choice as a standalone crossplatform language. But Lua is a great language to add scripting support to your application in a crossplatform manner (if your app is crossplatform, the better!). I think Lua will have a future and I think you can expect that this language will constantly gain popularity in the long run.
Warhammer Online, and World of Warcraft use it for their addon language I believe.
I think it's hot! I'm just no good at it!
Well, greetings from 2022.
It is already a general purpose language. Today you can even serve pages using OpenResty, extend games, read databases or create scripts as shellscript replacements.
There are a plenty of libraries "modules" for Lua, many ways to achieve what you are wanting and Lua 5.4 is even faster.
The "extendable and extensive" nature of Lua, accostumed people to think it should only be used as plugin or extension. In Linux, by example, you can shebang a file with lua-any, make it executable and run like any system script. Or you can make a folder app like Python or virtualenv using Lupe. Lua 5.3 also gained impressive performance improvements.
Also there are many good tools like IUP to create native windows in Lua for Mac, BSD, Linux and Windows and side environments like Terra that lets you use Lua with its counterpart Terra and write compiled programs. Lua now, is more than a extension language, it has its own universe.
