I am an amateur programmer working on some personal music software. Under Win98 and VB5 I wrote a routine that used the WinAPI involving callbacks to find, open and process real time input from a MIDI keyboard.
Revisiting the project after installing VB2010 Express, I am having trouble getting my head round the colossal increase in size and complexity of the language. In particular the need to use delegates to legitimise callback functions is puzzling me deeply.
I have written code which runs error free but nothing actually happens when I play the MIDI keyboard. I need help with understanding the program structure and relationships needed to create a midi_device class with methods to open the device, respond to the realtime inputs and close the device. Thanks for any help, David T

Take a look at some of these articles[^], which may help to explain things more clearly. If you have some specific piece of code that is causing problems you can post it here and people will try to help you.

Thank you for the references to delegates, which will be helpful. I was already well aware of the analogy of function pointers inherent in delegates. I will take up your suggestion and will code up a minimalist version which opens, handles midi messages and closes the device and see where that takes us.
I have copied code examples before for handling callbacks via delegates but never got anywhere. I suspect that because most examples are not complete viable programs, I must be getting something wrong with the overall program structure. Oh for the glorious simplicity of Dartmouth BASIC which I started with in the 1970s !!

can't save a VB6 project with flash10.ocx control. how to fix it?
|
|

By moving to something more modern. Implement new functionality with VB.NET, and integrate that into your legacy-VB6 project using the InterOp Forms Toolkit. That's a free download that can glue VB.NET code into your existing VB6-code.
Thus, glue new functionality in there with VB.NET, and try to migrate the rest as soon as you can. VB6 will apps will run on Weight, but there's no guarantees for Wine or Wen.
By the way, why couldn't you save it? Did the IDE throw some kind of message at ya? If yes, could you kindly post it here?

Well, with the total lack of detail and any error messages, the best anyone can tell you is that you screwed something up.
Seriously, why are you starting new developement work in VB6? It's been dead and unsupported for YEARS now. VB.NET Express is free and downloadable from here[^].

True, but can still create programs from it and it still works.
Simple Thanks and Regards,

Been programming in Visual Basic for 4 years this point forward, and is very good at it (I can even create programs completely on code, without dragging those items from the toolbox). Programming C++ for 1 year so far and the same with C#.

and you can learn a bunch of bad habits from it that you're going to have to unlearn when VB6 no longer works at all.

Please Help me with this I will make you a program on visual basic 2010, im just learning visual basic 6.0. I have made a lot of programs with it but im more familiar with visual basic 2010, I found that they are almost the same, but anyway I need some help with this program. I would up load it here but it says the file is to big. So thanks, Oh I can program using C#2010 or C++ 2010 and visual basic 2010 just tell me what you would like on a program and what language you want me to use. Thanks for looking at my post, Oh, I tried to e-mail, but the owner has not got back to me. Thanks. http://www.mediafire.com/?7k4zrq5c6n7a2hh[^]

Sorry, but nobody is going to download some file(s) from a web site in order to figure out what your problem is. If you have a technical question then post it here and include any extracts of your program that is causing you problems.

I'd like a program that generates next week's winning lottery numbers for UK lottery - must guarantee they are winning. You can choose between a Lisp or APL implementation.

mediafire with curious file name..
i won't download it.

All files on mediafire look like this (I use it myself) but I still wouldn't download it!

If you are trying to share source-code, then take a look at the article-section. I doubt that there will be many people who are going to learn VB6, as the language is on it's way out. If you find both languages very similar, then it'd be wise to switch to something from this millennium, not the past one.
This site has got 8 million+ members. I don't think that the owner will have the time to respond to personal emails very often.

i've heard it called true basic, but i'm talking about the basic i learned in 84. i was good at that, and i'm trying to write a program in basic, but can't find a compiler. i looked on the internet all day today with no luck. specifically, i need to know what file extension to save, if i need to use anything besides notepad, and if i need a compiler. thanx

take your pick here[^]. Took me 5 seconds to find.
I expect most of them use .BAS by default and accept any extension you specify explicitly.

You need to look at what you are trying to achieve, then decide on the tool to do the job (it won't be basic BTW) then look at the requirements for those tools.
A better question might have been - I want to achieve X, what tools will be easiest to use to do this (background, basic 25 years out of date). Good luck with that one

It's called Small Basic[^] But it's not like QBasic.

If you're serious about Basic you may want to invest some time in studying VB.NET. Microsoft offer a great free IDE[^] which includes all the tools you will need to get started.

they don't really help. let me expand on what i'm doing. i'm trying to write to the hd directly and use the basic i'm familiar with. i studied python and visual basic as well, they are not really suited to what i'm doing. the basic i used is called ti basic, found that last night. i found a bunch of variants, but i may as well use vb if i have to use one i don't know. i'm thinking i'll have to use assembly language to get the job done, it involves writing repeated 1's to the hd, then 0's, then 1's again. from what i'm reading, ti basic would be great for this, but i can't find a compiler that works. if i can find some way to interact with the drivers of the hard drive, that would be the best way to do what i'm trying to do. like tell the driver to write to the hd til it's full, the do it again. i know i could use debug to write to sectors of the hd, but if i mess up, there goes the box i'm working on. it's sort of advanced and may well be above my level of expertise, so if you can't help me, i understand.

What system do you expect to run this on? If it's Windows, UNIX or Linux you should probably be thinking of using C/C++ as you will most likely need to make system calls that are not so easy to do in Basic. I would be interested to know what you expect to happen when you tell the disk driver to write to the disk until it's full. More than likely your system will stop dead.
