Does anybody have an example on how to access the Win32 API from EU? I need to access a particular API function. Thanks, Marcus

You *could* be a bit more specificThere are literally thousands of examples in hundred's of programs on the EU contributions page, as well as examples in Euphoria\Demo\Win32 It's all done thru link_dll, define_c_func, define_c_proc... one way or another...

Hello, If you want to spend the rest of your life figuring out Win32lib then more power to you but if you really want a leg-up on Win API then, I would suggest getting a book and actually reading the explanations the author gives for each API routine...A C/C++ language book that got me started was Windows Programming Annotated Archives Code with Commentary by Herberb Schildt. Probably cant find this particular book anymore but there are dozens like it. Win32lib will only make your head swim simply because its far more advanced than you need as a beginner. Sorry Tone to step in there but if he doesnt know what API calls do then Win32lib wont help at all.

----- Original Message ----- From: "Euler German" <efgerman at myrealbox.com> > Euman, > > What about ol' Petzold's Programming Windows 95? Do you think it can > help? > > -- Euler I have never read the book but I think David started Win32lib by basing the code on that book. I think if you ask Derek if he would have done it this way he'll tell you no and maybe even David dropping the project may be due to the way he started the library and not wanting to go back and change everything but, this is just a guess......So, dont base a project on what you learn from one book! There are too many lines in Win32lib that make the library redundant, over sized and slow.."note: I didnt say very slow". I dont know enough yet to comment on how it shouldve been written but I have ideas. Anyone who uses Win32lib is stuck in the loop of having code that is poor in performance, size and bug ridden. Currently there are only a handfull of people that can write code for Win32lib so your stuck if you have a bug creap up. Learn to write API from the get-go and you'll be better off in the long run. Write your own darn code then you'll feel better about yourself and learn more, faster...Programs will take many times longer to develop in the beginning but well worth the time spent researching info either on the net, from books or the MS-SDK. I would like to see Win32lib answer what this API means to a program seterrmode = define_c_func(kernel32,"SetErrorMode",{C_UINT},C_UINT) junk = c_func(seterrmode,{SEM_FAILCRITICALERRORS}) hehe just a joke Derek, Matt, Wolf, David..etc Euman

I can speak to a couple of these issues, but keep in mind that I haven't really looked though Win32Lib in a while - there have been quite a few changes since I (gratefully) left it with Derek. Win32Lib was written for ease of use, and (especially with Judith's IDE) I think it's achieved that. The tradeoff, unfortunately, is speed. A case in point is the handling of fonts. The old version of Win32Lib basically created a new font every time there was a call to a routine that used fonts. This was horribly expensive, but it hid the nasty details from the user, and (attempted to) prevent resource leaks. As for Win32Lib is 'bug ridden', I suspect that's a bit harsh. And keep in mind that the author of any software program can't fix bugs they don't know about. So one of the best ways to fix Win32Lib is to report any known bugs to Derek. Sure, you could 'roll your own' version, but in retrospect, I wish that someone else had written Win32Lib, so I could have been doing more interesting things. Just my (probably obsolete) two cents. -- David Cuny

I, for one, never would have been able to start programming in Windows without Win32Lib.

Not to mention that if I tried to do natively what I'm doing in Win32Lib (and I have tried, and gave up quickly), I'd be bald by now trying to find the one line with the wrong parameter. I'm very grateful to all those who have found the bugs for me, added features I could never figure out, and prepackage it in such a way as to make it a real solution to real problems. > Just my (probably obsolete) two cents.

Actually, it was euman who wrote that (no surprise). However, he could have said exactly the same thing about Windows itself. - if you use it, you are "stuck in the loop of having code that is poor in performance, size and bug ridden." Even the dozen or so people in the world who write Windows programs in assembler don't gain much in the way of speed or stability, so where does the blame really lie? > David Cuny wrote: > > Win32Lib was written for ease of use, and (especially with Judith's > > DE) I think it's achieved that.

I had really bad experiences with VB a few years ago, and I don't expect enough improvements have been made that it would now suddenly be useful. I certainly wouldn't waste any money to find out. But all of that's academic, because I now avoid Windows whenever possible. Regards, Irv

I use win32lib because I just don't like the POKEmonish code (allocate,poke,c_proc, free) Without having most of the code constructing the API calls, there's more time for focusing on the actual problem. It is apparent that creating an API over API causes some speed/functionality loss. I also don't want to binded too much to Micrsoft and their API. If we had kind of cross-platform win32lib... That's just my opinion. Martin
