You could get some ideas from the GDI implementation in Wine: search keywords in repository : https://github.com/wine-mirror/wine/blob/6d801377055911d914226a3c6af8d8637a63fa13/dlls/gdiplus/graphics.c GdipDrawArc From there you get GdipAddPathArc and then https://github.com/wine-mirror/wine/blob/6d80...

Alternatives could be somthing like SQLite or Firebird as embedded Database: Firebird could also later be easily changed to client/server mode Squirrel or Lua: Loading lua tables: https://www.freebasic.net/forum/viewtopic.php?f=7&t=22223&hilit=+Lua#p195498 For saving data you could use Serpe...

I had some ideas a while ago making macros much more powerfull. Introducing some macro statements for context handling would be great.

There could be some possibilities to optimize the alghorithm for speed or even for memory consumption, but first you must define the parameters define "set of numbers" the range / any negative numbers how many are there duplicates are they random or ... define the number "optimum sum&...

The world of the barebones is very diverse If i understand you correctly, you want to work and compile on an embedded system or a thin client. But why dont you use a normal workstation/notebook to do that? To test the program you can use than your embedded system. You also could use a VM with the l...

NASM has a very powerful preprocessor. It's so powerful that you can create things like nested block statements: for/next if/elseif/else/endif blocks .. Thats because of a very simple but powerfull context stack : so we would need something like #push|#pop|#set context #if defined(context) so we onl...

Ten years ago we still used a factura program / database based on OpenAccess4. It was so fast.. with only 2 or 3 key strokes you could be in any subprogram in less than a second. It did run well on Windows 32 bit. In DOS there is often only one way to do things UI wise. That makes it simpler after g...

Another option is to use ASM with AVX / AVX2 instructions: Each YMM register can hold and do simultaneous operations on eight 32-bit single-precision floating point numbers. So basically if the algorithm could be optimally transformed you could gain almost 8 times the speed. Realistically it could b...

Maybe it's faster if you change this by using less divisions df=((-1e12 /Rgquadro)/Rgquadro/Rgquadro)+.4 also you could change the select case: 'Maybe ? Dim as Double Rgquadro If Rglue >140 Then df=9512/((Rgquadro)) Else If rglue>= 10 Then df=((-1e12 /(Rgquadro*Rgquadro*Rgquadro)+.4 Else df=0 NUM_ER...

Keywords like Name, Width, Color can't be used as properties or membervars in types, that's a bit annoying. That would be no problem if most keywords get out of global namespace.

If you work with RANDOM files and Type records it's important not to use "As Integer" . Just "as Integer" could be 4 byte or 8 byte weather you compile for a 32 or 64 bit platform. . So if at some point you are changing platform, it would break file format compatibility and you c...

I have been thinking for a while about the quirks and about namespaces or some sort of package system. I would introduce some sort of auto namespace mode, which reflects the directory structure. Also things like an auto include mode or a compiler project / options file would be nice to have some com...

This code does the same as Joshy's but can be run from both QB and FB. So with QB you could actually write readable code.

Regular expressions are very useful: search pattern: ^(\t*)[ ]{3,5} replace with: $1\t Explanation: linebeginning followed by arbitrary number of tabs followed by 3-5 spaces and replaced by preveoiusly found tabs + one tab replacing 3-5 spaces. search and replace several times with notepad++ Spaces ...
