D++ is a scripting language that can handle things like basic I/O, if statements, variables, expression evalutaion, and more! It can compile the applications into executable files. Although it does NOT compile a true Win32 application, it compiles your source with a DLL to create a valid Win32 application by coping the DLL (blank app with built-in linker) and your source code and making a new EXE.

OK, so this doesn't do much yet but it's pretty unique and unless someone can show me something better then my "excellent" vote sticks! Ofcourse it's slow, C++ is slower than assembler because C++ is written in assembler (?) and VB is slower than C++ because it's written in C++ and D++ has to be slower than VB because it's made in VB... did that make any sense? Anyway keep it up SqueakMac. (If this comment was disrespectful, please report it.)
Yes, a interpreter will of course be slower than the language it is designed in, but there is so many levels of "slower than...". According to your logic, "Slower than VB" and "Much slower than VB" are the same? ;)

I get fairly good performance out of my own Script Engine, so I do not believe it is neccessary to do it in C or ASM. I haven't benchmarked it but I think it would be a couple of 1000x faster than this one. I think it it important to say that you can make a program go *really* slow no matter what language you are using, but if you optimize it the choice of language does not matter that much. ;) (If this comment was disrespectful, please report it.)
And guys ... don't expect him to write this program in ASM or C++. That get's rather friggin' tricky. Especially writing windows programs in ASM. VC++ I can understand but I don't think he's that knowledgable.
After talking to him I think he only knows Basic. Although, he'll probably become the next Linus Torvald here in the near future. So don't diss on him. ;)
Peace Squeak ... (If this comment was disrespectful, please report it.)
you people saying to make it in c/c++ or asm, its hard enough making it in vb, c/c++ and asm is a great deal harder,i'd know hey squeack, ignore those that as just being lazy and copying source -Nova Ice (If this comment was disrespectful, please report it.)
Hey, why does everyone say remake D++ in C or ASM? Last time I checked this was "http://www.planetsourcecode.com/vb"
Anyway, nice project Squeak. I don't know where they got the "slow" D++ stuff from. Ran fine on my machine.
Oh yeah... check out some encryption stuff on PSC. I bet you could encrypt the syntax of your scripts pretty easily to make it look like your own save format. Would be cool in my opinion. (If this comment was disrespectful, please report it.)
If people are truly worried about speed then they must have been the old school programmers working on 8086 processors trying to conserve space and make it fast. I can understand efficiency back then but efficiency is totally different now.
With our fast computers its only microseconds less of time in VB. So who really cares? Bill Clinton called a 1 GHz computer a super computer back in '95. Now we can own 1 GHz computers for a couple paychecks.
Except for maybe those people with P133 and 8 megs of RAM everyone shouldn't be picky about microseconds of speed. (If this comment was disrespectful, please report it.)
As far as you writing an interpreter at a young age, I am a little bit impressed. As far as how well it runs (not considering your age), and the style in which the code is done, I'm not impressed. (If this comment was disrespectful, please report it.)
Using VB instead of ASM also gives you a lot of functionality "for free". Try making an interpreter that supports forms, controls, objects etc in ASM. Yikes! (no wonder M$ needs a lot of time to complete VB7 ). (If this comment was disrespectful, please report it.)
to all the people who seem to think maximum optimisation is not needed (in any code) - well that's just down right selfish and rather crazy ! who is the code for ? you or your users ? if it's for your users then OPTIMISE OPTIMISE and do MORE optimsising ! they WILL appreciate it and NOT everyone is able or willing to spend a "couple of paychecks" on some do-everything GHz computer ! just so they can test some vb source code example ! meaning - if code is OPTIMISED audience is also MAXIMISED meaning YOU get more CUSTOMERS and if commercial (or vote based) YOU get more MONEY or votes ! c'mon now think about it sensibly people ! sheeesh ...... (If this comment was disrespectful, please report it.)
Hey SqueakMac remember me? Well I am sure you do. Wait till you see my version of d++ (v2.5). Its like D++ and D++ IDE on crack...its MMAADD. I am sure you all will love it. Expect it as soon as psc will let me upload it. Which, by the way, I have tried 4 times. (If this comment was disrespectful, please report it.)
Better yet, forget all the people saying to optimize! Abandon VB! Screw C++! Don't worry about ASM! If you REALLY wanna be 1337, write it like a TRUE programmer: in straight machine language! (end sarcasm here) Nice program, but just try not to get too boastful about it like you did on JEL. (If this comment was disrespectful, please report it.)
Man.. u lot r f**ked. He has done it as an example of what vb can do.. not as a program to be marketed. And another thing.. its not slow.. its just all your computers are crap!!!.. it works great on my pc, and runs as fast as anything written in C. If u so desperatly want it in C, write it urself.. and actually help the open source world to continue. (If this comment was disrespectful, please report it.)
Well I gotta agree do it in c or c++. Maybe even assembler. I have written a basic scripting engine in c though it wasn't to work as a stand alone script language. As for optimizing it is true you can optimize any code to work faster but realisticly the slowest c code will beat the fastest vb code any day. Personaly I only picked up vb because I had to for school and I found it instaly easy. If you really want to become good at a language don't start witht he basic. Try something harder like c. When you need a basic language then you'll find it to be extremly simple. So basicly I'd say yeah take some time to learn c/c++ (prolly c for this because it is faster slightly than c++ and I prefer it in general) and try writing it in c. If you really want to go for it you might be able to eventually create your own true language. VB is a very limited language in a lot of aspects. And for those who think vb can do anything c can do I recomend you learn some c. (If this comment was disrespectful, please report it.)
Good Work Squeak !!! Me too i've 13 years old and i'll try to beat you :) Wait for my next script, you will see :) (If this comment was disrespectful, please report it.)
Hey Squeek, I think its good & I'm impressed. As for writing it in C++, it would be hard. As for writing it in ASM (Win32) can anyone do that? Cos if you can, I wanta talk to you! (If this comment was disrespectful, please report it.)
People still saying do it in C++ or ASM?!? I tried to remake this in ASM after I downloaded it, my ASM file got to be 9583 lines, and it didn't even have the compiler part yet! Don't tell someone to do something in ASM unless it is a very basic program, a keygen, or C++ with inline assembly in some parts. (If this comment was disrespectful, please report it.)
Here is a idea- Program it in VB, then decompile it and go through the code BY HAND, fixing and optimizing it as you go- VB adds ALOT of content to the file (Subs,things like that) that are NOT EVEN USED IN THE PROGRAME... so go through it and take out all the cr@p. (If this comment was disrespectful, please report it.)
Ahh Squeak has done very well. and about that slow. it is indeed slow if you compare it with C or ASM. But remember this is a interpreter coded by a 'kid'.
I'm waiting for 'BlueLighting', it might be way faster :-D. (If this comment was disrespectful, please report it.)
D++'s maths parser (if it can be called that) is blown out of the sky by practically all other VB scripting languages I've seen. Apart from that, with a little work and conversion to C++, it'd be pretty good. (If this comment was disrespectful, please report it.)
People here, who thinks that VC++ is written in ASM ?! VC++ is written in C, of course it is used ASM in. How do you think that the complete VC++ can be written in ASM. It would take ages. And even MASM is written in VC++..
You did a well coding but if you want a real compiler, you should directly access memory (vb cannot do that) and have a powerful control of strings (C/C++ is best for it) And i think if you programme it in C/c++ it will be easier for your code handling after a moment. Or you can simply programme the editor part in VB and the compiler in C (i advice.)
See you.. :) (If this comment was disrespectful, please report it.)
Well well, quite a living conversation going on here. The only thing i want to add to this is that this code finally has practical use. It's not 'Unfinished chatprogram' nr 100 or useless function nr 1000 but a real working program. Keep it up, SqueakMac, good coding ! U know it, Visual B. rules !! (If this comment was disrespectful, please report it.)
For all of you who think that vb is just a "SLOW" language. HA. VB6 is a little slow. But VB.NET is as fast or faster then C# (If this comment was disrespectful, please report it.)
Not to be the "Odd man out" But it does not work on my CPU. Im running WinXP home and it compiles but then the D++ app that pops up is black. Zip Zero, Null, Nothing. But if any one has an comments about how to make it work just click on my name and E-Mail Me.

as for you people that keep saying "Do it in c/C++ ASM blah blah blah" Lol dont you people know the diffrence between ASM and VB? look ill show ya Visual Basic and the key word is: VISUAL you all go on like doing D++ in VB is easy... its not hard ill admin BUT the thing is Visual Basic, ASM and C/C++ are all totally diffrent... Vb is point and click... how many C++ compilers are as easy to use a VB? VC++ and Borland are the only things that comes close that i can think of at the moment... if any of you people that say do it in C++ are VC++ coders.. why dont you try to make something like this is lets say hmm Bloodshed C++ compiler... thats just to state the fact that VB and C++ are totally diffrent, C++ is on a ALOT Higher level the VB... so stop givein the kid a hard time because its VB not C++ and yeah it runs fine on my box, if your crying about speed its simple DONT USE IT... use Python or Perl (If this comment was disrespectful, please report it.)
There are alot of replies here, and i didn't have time to read them all. But i did see Simon Price' one. This is how I have understood it: x86 Assembly | ---| C------------ | | C++ VB

...and...to write something like this in 'MASM' doesn't seem that hard these days. MASM has many new features added to it that allow for Macros. There are some already programmed macros for programmers to use, such as InStr, Mid, Left and Right. Although the older ASM languages are harder, they aren't as hard as many people believe...
Phreak (If this comment was disrespectful, please report it.)
Oh God, what the ... you are talking about, the best way to write programming language is to write it in vb or c++. Here we make IDE, syntax highlite and stuff like that. Then we simple take the code, convert it in ASM code, not hard att all, like declaring variable will be like two lines of code in asm. Then wenn this translator which is best ot be writen in c, easy to write and fast enough, we take our assambler, writen in asm if possible, and simply convert asm code in hex. Simple as that, and you have pure application writen in asm. (If this comment was disrespectful, please report it.)
Interesting. I am making my own language, uisng your dll writing. It is currently write text, though it'll improve. (If this comment was disrespectful, please report it.)
