Okay, I looked into the sourcode of VLC (which is able to disable screensaver on my PC), and I found out that it calls simply some commands in a periodic way: xdg-screensaver reset xscreensaver-command -deactivate gnome-screensaver-command --poke I will have to test if it really works for my program...

From your question I guess that my hope for a portable way is hopeless :-P

In my case, this is a the KDE power management that shuts my screen off, but it's me - for other users it could be a Gnome screensaver, or a Windows *.scr...

Hi, I am working on a little FreeBASIC program, which do not take any keyboard/mouse input. After few minutes of work, my OS (linux) is starting a screensaver, and I have to press any key or move the mouse to get back to my program. Is there any (hopefully portable) way to prevent the OS from launch...

@TJF: Ah zoo, ich spreche kein deutsche. Das ist a hund. Pommes-frittes bitte. (and that's it about my german skills) :-D But I will definitely look into these examples, looks interesting (and maybe passing the whole website into a translator will help me to understand what it's about) :) @dafhi: Ye...

Hi all, thanks for all your suggestions :) I replaced all my DIM declarations by STATIC declarations, but it doesn't changed the overall speed in any noticeable way... Still, the most consuming part is the operation of writing to screen. @TJF: I have absolutely no experience with hardware accelerati...

I hope I am not mistaken, and here are some very slight improvements in the loops Merci cher compatriote! :) Thanks, I edited my first post to add your optimizations (and also added another very little one that I noticed now). Still, as you say - these loops optimizations are really thin, and doesn...

Hi all! I am currently working on a program which is trying to refresh the screen at a rate of ~60hz. Unfortunately, this is painfully *slow* :( The screen size I am working on is 160x144 magnified 4x (that is really 640x576). This is my current code: #MACRO DetectScreenChanges() LcdModified...

What about this one?

Anybody knows how to perform Base64 encoding/decoding on a file in freebasic? Hi, Here you will find a neat FreeBASIC function to encode a string into Base64: gopher://gopher.viste-family.net/1/fb-stuff/ I extensively tested this function, and it works very well (I'm using it in my web server proje...

Hello! Thanks evryone for your attention! :) @TJF - Yes, this is exactly what I was looking for! I am totally discovering the declaring-functions-as-variable stuff, and I am amazed that such cool tricks are possible with FreeBASIC. I am using that now in my program (declaring two different functions...

Thank you all to your valuable input! I don't knew that casting an UBYTE into a BYTE will just "make things happen" - and indeed, it seems to be the fastest possible way. I replaced my overkill function by #DEFINE UbyteToByte(ub) cast(byte,(ub)) ...and I assume it is impossib...

Hello, I am playing with one of my programs, trying to make it as fast as I can. The program is processing data coming from various files, and there may be two different types of files (each type requires a different processing). I wrote two different functions, each function is specialized into pro...

Hi people! I'm looking after a way of converting a UBYTE representing a 2-complemented number into a signed BYTE. So far, I am using this: FUNCTION UbyteToByte(BYREF UnsignedByte AS UBYTE) AS BYTE REM Returns a signed value from a two-complemented integer IF (UnsignedByte AND &b10000...

Thanks to both of you, I truly appreciate all the information provided here. Somehow the window that pops up is still fairly small, is there a way to make it larger or even fill the screen? Sure, but it won't be SCREEN 13 anymore. You need to use SCREENRES instead. SCREENRES 800, 600 SLEEP or, for ...

@Fox Only the q key actually responds with your method. That's because you don't use my method - you sabotaged your own program :-D You're making a "SELECT CASE UCASE(LastKey)", and then looking after "CASE "w"". There is no suprise that it doesn't work - an UCASE won't give you a "w" ever. The "q"...
