• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

Lessons on development of 64-bit C/C++ applications (conversion from 32-bits into 64-bits)

On my path to find (online) material to help refresh my ancient (ANSI / Turbo) C_Coding skills,
I landed on this wonderful PVS-Studio webpage about 64-bits coding - lessons:

Here are the links to the relevant 64-bits lessons
- https://www.viva64.com/en/pvs-studio/ - Homepage
- https://www.viva64.com/en/l/full/ - All 64-bits related articles in 1 big web-page
- https://www.viva64.com/en/l/ - all 64-bits articles separate

I'll hope you will enjoy the articles :)
 
Hi Ronald!

I would not worry about writing code for 32bit or 64bit so much, unless you are writing in a language like Assembly. Assembly you deal directly with the CPU's registers and there for have to take into account if your system is 32bit or 64bit. But most of the languages used for programming now are very high level programming languages. They are more text based, so that we the programmer can read the code more easily. And then we use a compiler to re-write the code into a language that the CPU's will understand.

So in short don't sweat it! Just concentrate on learning the logic of what programming is and the syntax of the language you decide to use.

Hope this helps you!

Thanks, Kris

This topic might appear on my low-level coding agenda in the near future, Kris.

Thanks for your reply.

@krispy1001 If he is going to use C++ then he does have some quirks to deal with in the x64 vs x86 environment. Specifically when casting pointers into integers. You can't cast them into UINT32 or DWORD in the x64 environment or you will end up with memory access violations. Secondly, he will have to use separate libraries for x64 vs x86. But otherwise there is no concern.
