[Freedos-devel] new app: scrsave
Hi, I am releasing this app under public domain. What it does is quite simple: it saves the contents of the screen into a file c:\screen.txt, once every 3 seconds. I am releasing this code to public domain since: - GPL is too restrictive, and it is many times problematic for incorporating into commercial products. - I am having some problems, and I feel that if more people are exposed to the code, they will be able to fix it, or tell me what I am doing wrong. Problems: the app displays a char on the right upper corner of the screen, which indicates that is it working. I start the app, and in commmand.com it works. I type some commands (like dir of something similar) and I can see the commands output on the text file. However when I start prorams like "turbo pascal" or "edit" or "dos navigator" I still get the old command prompt on the text file. The funny thing is that I see in the right upper corner my app runnning. All the screen handeling was done by reading or writing from segment B800. In TP code it looks like this: Type VGA_Screen = array[0..25-1,0..80-1] of record letter: char; color: byte; end; Var Screen: VGA_Screen absolute $B800:; The I just read or write to this variable to read or write to the screen. If anyone has a better approach, please do tell. I also need to implement "virtual keyboard input" from a text file. I found function 5 of int 16h which can help me, however some tests I have run did not work: procedure send_key( ascii: char; scan_code: byte ); Begin asm mov ah, 05h mov ah, scan_code mov cl, ascii int 16h end; End; I send some chars to this function and then I did a readln. I expected to get the letters sent to this function and the ones I actually typed on the KB in the string. However I got only the ones I typed in the keyboard. The app can be find in: http://cucomania.homelinux.net/pub/dos/scrsave.pas http://cucomania.homelinux.net/pub/dos/scrsave.exe I compiled under TP 7.01 (the one from the french borland site they gace away some years ago). I can port it to C, and probably will in the future. -- diego, kde-il translation team Please avoid sending me Word or PowerPoint attachments.

Hi, I think you will be able to capture the screen in Borland IDEs by simply making your program check which screen PAGE is in use. You can find that information in the 0x40:xx BIOS data area. Public domain is okay - easier for people to use your code in other programs. But GPL does not limit people in reading your code either! It only limits people in what license they may use for derived works. And of course you could port it to Turbo Pascal 5.5, of which even the English version is available for free from the Borland community museum. Or to C or to Assembly language or whatever you want :-).

But GPL does not limit people in reading your code either! But it limits them by not giving them perision to reuse this code in their projects. I dont like the virus effect of GPL. MIT might be a good idea... maybe next project. > It only limits people in what license they may use for derived works. I dont get it... Page N is in B800:[80x*25*N] right? I tested it... (I made an arrays of screens, and printed all of them into a file. and still I can write to the first line in the screen ... so I think I am seeing page number 0... I will test again. > And of course you could port it to Turbo Pascal 5.5, of which even > the English version is available for free from the Borland community > museum.

[Freedos-devel] Joke of the day: lb040501.zip !?
Hi, I got an urgent request to make my homepage 8.3 name compatible. So I would have to upload lbacache-01may2004.zip as lb040501.zip (which is YYMMDD order, nice for sorting but completely unreadable to normal Germans). The claim is that (paraphrasing) "having to use a web browser to download non-8.3-filename and save it as 8.3 filename on disk would be contradictory to GPL". I hope that even web browsers for DOS are able to use URLs which are longer than 8.3? In that case, I assume that it is possible to download the file under every 8.3 filename that the user wants. For extra convenience, I wrote a shell script which helps to mass-rename files: echo mmv lbacache-\*\?\?\?20\*.zip lb\#5\#2\#4\#1.zip Uhm, sorry, must be: mmv lbacache-\*\?\?\?20\*.zip lb\#5\#2\#4\#1.zip ;-). Whatever. Sample result: Before -> lbacache-01apr2003.zip lbacache-10jun2003.zip lbacache-20sep2003.zip After -> lb03ar01.zip lb03jn10.zip lb03sp20.zip You could make that a bit more sophisticated to replace the months by numerical versions. Have fun. If you are REALLY downloading my software under DOS, and your browser is unable to process non-8.3 URLs, let me know. Doh.

[Freedos-devel] MHCOMD.VBX module
Hello all. First of all, please accept my apologies for posting an off-topic message. Second, I don't know whether the request that I'll be doing is considered piracy or not. If it is, please accept my apologies for that as well and just disregard this message. The point is: while assisting a client, a program stopped working because it lacks this MHCOMD.VBX module. If is there anyone out there who has this module and could send it to me, I would be very grateful. There is this BIBLIO program which, after the HDD being reformatted, it stopped working. As soon as I double-clicked that, it called for a GRID.VBX module which I was able to find within the (very old) floppies of my client. I copied it into the HDD and the program then called for a CRYSTAL.VBX module which luckily I was able to find as well. Then, the program called for this MHCOMD.VBX module... Which I didn't find anywhere (within the floppies that were still readable). I tried the web as well. No deal. Furthermore, if any of you could point me to some other mailing list where perhaps I could find help, I would also be very grateful. Thanks to all for your attention, have a nice day, Henrique --- This SF.Net email is sponsored by Sleepycat Software Learn developer strategies Cisco, Motorola, Ericsson & Lucent use to deliver higher performing products faster, at low TCO. http://www.sleepycat.com/telcomwpreg.php?From=osdnemail3 ___ Freedos-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/freedos-devel
