A close to authodox API Window.
« on: July 01, 2016, 07:22:41 PM »
I have kept working on trying to get a basic window that looks more like conventional API code. It would seem that any procedure that has more than 4 arguments needs to have a stack frame. Those with less arguments appear to work fine with no stack frame as do pure mnemonic procedures. Something I found unusual was that I could not get a clean exit with the window unless I specifically used SendMessage to WM_DESTROY from the WM_CLOSE message location.

This is the test piece.

You seem to allocate spill space, call GetModuleHandle then reclaim that space, leaving none for the other API calls.
Maybe you're lucky with the spill being absorbed by the locals?

The problem is the documentation is so poor that I am writing this stuff by test piece to see what will actually run.

JJ,

These are the assembler and linker I am using. It looks like you are using the 32 bit version of ML.

sinsi,

It works just as well with the following. I think its Vasily's macros providing the spill space.


    ;;; mov hInstance, rv64(GetModuleHandle,0)

    invoke GetModuleHandle,0
    mov hInstance, rax


This is what the proc entry and API disassemble to.

That could indeed explain something. Mine sits in C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\ml.exe
I didn't know that there are separate 32- and 64-bit versions of VS :(

I'm using ver 12 which  is 64-bit, came from vs13 iirc.

Hutch,

Thanks a lot, now I could build (and debug) my first 64-bit program :t

I feel a bit uneasy about Vasily's libs, includes and macros, though. Once adopted, they will effectively block the road for the Watcom family assemblers, the main reason being that it contains workarounds for the crippled ML64. And he is not a particularly active member of our forum, too.

OTOH the other assemblers seem to drift apart a little bit, and I can't imagine following (macro-wise, commandline option-wise) several idiosyncratic forks. It was a lot of work to keep my baby compatible to ML 6.15...10.0, JWasm, AsmC ::)

I don't want to spoil the party here, especially because I don't plan to become an active 64-bit fan. Playing around, yes, real work, no :lol:

The good news is we are beyond the last remark:
It might be helpful to have a sticky post in the 64-bit forum with a "Hello World" archive containing
- basic includes (kernel, user, msvcrt, ...), or at least exact links to them
- basic libs, or at least exact links to them
- a batch file that takes an asm file as argument
- a link to the version of ml/jwasm/hjwasm/asmc that works with the hello world
- a link to a free 64-bit debugger

So far, I find it far too confusing to even start playing with 64-bit code 8)

But it would still require work and discipline to arrive at a "starter's kit for 64-bit assembly" that is as easy to use and consistent as the Masm32 libraries and includes.

P.S.: Window 3 builds, but only without resources:

Impossibile avviare il programma perché api-ms-win-crt-runtime-l1-1-0.dll non è presente nel computer. Per risolvere il problema, provare a reinstallare il programma.

That it's in Italian is part of the problem: No help from the internet... Microsoft crap, DLL hell version 2.0.

Google translate
Unable to start the program because bee-ms-win-crt-runtime-l1-1-0.dll is not on the computer. To solve the problem, try reinstalling the program

Does the version with resources and manifest run OK ?

Your exe runs ok. It's cvtres that complains... edit: ok after installing Visual C++ Redistributable for Visual Studio 2015

that may, just possibly, be true. Perhaps.
