Re: [Gambas-user] Gambas 2 - Gambas 3
Good morning Benoit (and everyone) Just came about a question: When I want to bring my Gambas2 app to Gambas3, will this be as roundabout as it is from Gambas1 to Gambas2? (Creating new forms and converting the code...) Or is it more upward compatible? The reason for asking this is that you told me that you would just maintain bugfixes in Gambas2 and bring changes only to Gambas3. As I'm still maintaining some bigger Gambas1 projects, I would then migrate them to Gambas3 directly rather than having them under Gambas2 - if it's as much work again... Hope I could make clear what I mean... Regards Rolf The weirdest thing between Gambas 2 and Gambas 3 at the moment is Desktop.Scale, that is smaller in Gambas 3. Gambas 3 does a little conversion for controls whose W and H = 3 * Desktop.Scale (it adds one Desktop.Scale), but you have to update all your forms and check them one by one to redesign them. There are many other changes in instruction syntax and class interfaces, but I never note them at the moment. Hopefully, they are less changes between Gambas 3 and Gambas 2 than between Gambas 2 and Gambas 1. So please try and tell us the result! :-) -- Benoît -- Open Source Business Conference (OSBC), March 24-25, 2009, San Francisco, CA -OSBC tackles the biggest issue in open source: Open Sourcing the Enterprise -Strategies to boost innovation and cut costs with open source participation -Receive a $600 discount off the registration fee with the source code: SFAD http://p.sf.net/sfu/XcvMzF8H ___ Gambas-user mailing list Gambas-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/gambas-user

Re: [Gambas-user] Locking files - best method
I think you're looking for the filesystem to prevent you from file operations while 'locked'. I used 'locking' with VB5 and relied on Window's internal locking mechanism. After years of agony, I found the external subdirectory method the best. I don't have shared files on just one computer, there are many computers. I found that VB5 sometimes got stupid and never unlocked - especially when long time between reboots. But now, with the subdir method, I can fully control it. I do this with Gambas using Samba while I port away from VB5. The main problem is this: Program 1 locks a file (or a portion of a file) and that program freezes up, locks up, computer is shutdown, etc WHILE the lock is in force. Then other programs try the same and The whole system is screwed! Now that I use subdirs, I know that a lock 'should be' free (ie unlocked) within 10 seconds because I know that there is no way my code should last that longand something is wrong. In such a case, I can actually proceed (fake re-locking it) with the second program, give a warning message that it couldn't lock because it is taking too long but is proceeding and will subsequently unlock (rmdir) too. In very few cases, I have had to go in and RMDIR manually because things got jammed up, but discovered those situations to be wierd-condition bugs which are now fixed.

Re: [Gambas-user] Locking files - best method
That's right. I tried your idea, and it works fine as long as every other program keeps looking for the dirs. My problem is similar: Part of the software runs on Windows, originally programmed with VB5. To make it compatible to the Linux side client, I introduced a lock-file scheme. It still uses that successfully. Unfortunately, I lost the VB source over the years :-( so it has to keep on running like that, and so has the Linux client. Luckily, though, we are only 2 persons in our offices who use this thing on a daily basis, so it's no harm. There are some other Linux programs meanwhile using the data, but do not write to it, so no real danger. But for my next-generation tool for the teachers there was trouble with my lock-file system, so I changed writing/reading to your lock-directory system. Easy thing, and up to now (a week or so...) it seems to be running well. I cannot use Benoits LOCK Stream here because this program is still Gambas1. I had your idea of waiting, but writing nevertheless and just give a warning as you do is even better. Maybe I'll change that part, but I'd prefer keeping the original and writing into temporary files until Admin cares about it... :-) As this application has a messaging system, I could even send me a message in this case!

A typewriter, those mechanical things that are only in black and white movies and museum actually performed CRLF using that bar to perform the line feed and carriage return. And CR LF comes from that. All the software I write for HTTP, ascii files, When reading, I only look for the LF. If I find a CR, I just ignore it. I have yet to find a case it normally doesn't work with. I agree partially with you - I don't like the CR-LF convention: I think that a single LF is enough. But your programs, even if they ignore LF when reading, still use CR-LF when writing (I hope!), otherwise they did not respect the standard. And about the standard... someone in the past said a single LF would be the line terminator. But someone else thought that CR was enough (Apple computers for example, and before, other mainframes like VAX). Then, still someone else thought that neither was good, and used CRLF. If the american DoD, from which our Internet comes, decided CR-LF was the way to go, they too had good reasons, I think, even if I don't know them. I admire so much who invented IP, TCP/IP, FTP, HTTP, that I take for good what they said: CR-LF is the right line terminator even if I don't like it. Pardon me for getting this so hot, I find it difficult to think that CR-LF is bad only because is so old... :-), the only important thing is to cooperate in a common standard. Well: the IP/TCP/HTTP/HTML standard is out there, and it works. It has been developed in full democracy (you know what RFC stands for), and so many different kinds of computer can intercommunicate, thanks to this standard. Do you want to say this is a stupid thing? And finally... I still use what you could call old museum printers, which need CR *and* LF. There are some around, even if you don't see them... the world is not only made from 4Gb ram computers and 30PPM laser printers...

Re: [Gambas-user] Help with some parsing
Hello Doriano, I have to excuse me - it was never my intention to insult your, as it seems deeper going feelings, regarding this particular 2 Bytes :-D Ofcourse you are right - they are (and will be in the future also) still in use... But here is the point where I do not agree with you: I do not know how old are you... My first date with CRLF was on my very expensive (4000 USD) Apple ][ with the huge ammount of 48 KB RAM, 16 KB ROM, 144 KB Floppy Disk and rare extension - Video Card allowing me to work with 80x25 chars instead of the usual 40x25 ... Not to mention the extraordinary calculation power based on the 1 MHz 6502 CPU ;-). So please excuse when I am calling this stone age, but my very simple mobile phone laying in my pocket offers 2 GB of storing capacity on volume that the old Apple used to store about 16KB and about 300 MHz RISC based power... It was not a try to reduce the meaning and importance of those command chars - but simply to show how long they are in use... Very best regards And one more time excuse my lack of respect Emil Tchekov -Ursprungliche Nachricht- Von: Doriano Blengino [mailto:doriano.bleng...@fastwebnet.it] Gesendet: Dienstag, 17.

I disagree, chr$(13) is CR; chr$(10) is LF. While it is true they are an old standard, saying they are from the stone age is not fair. HTTP protocol relies on CR-LF, and you must admit that HTTP protocol is well alive - not a stone age standard. The fact CR-LF is so old is a proof of its power. Moreover, text files are the most expressive and versatile form of digital data. Html, Xml, Svg, Postscript, PDF, are all in wide use and are based on ASCII, and so they contain CR-LF sequences. The fact Unix/Linux uses a single LF instead of a CR-LF is pretty marginal - it was simply a design choice. A windows HTTP server can take text files from disk and serve them verbatim, while a Unix HTTP server has to translate them (to add the missing CR). Anyway, the concept is the same. Most programs today can cope perfectly well with this two standars. In the end, the only thing I wanted to say is that CR and LF are far more than what you depicted, and they are still needed.
