Program to sum two numbers

[dedndave]

Michael posted a batch file
give me a little time - let me see if i can make it work   :P

[blue]

I tried to make it work and I assume that the framework.c must be compiled to an .obj file and then linked but I don't know how.

[dedndave]

i think you have to assemble io.asm to make io.obj and link it with your obj
give me a few minutes...

[dedndave]

yes - we have been trying to make things work in the console
and, apparently, some have had success with it too   :eek

it seems the framework files provide a dialog box for the results to be displayed
there must be a procedure in the book
have you skipped some chapters  ?   :P

the framework app could be re-written in asm
or, you could try to make the thing work in the console

the easiest path is probably to follow the book   :bg

i am not really a "C" person - lol

[blue]

I haven't skipped any chapter. I think this book is not for a beginner in assembler as far as I get these stupid errors. I think the book itself is stupid.
Anyway, the problem is with that framework.c: getInput and showOutput.

[dedndave]

i am looking at the book, now
page 10 gives a procedure for building this project (well - it's page 10 on the web)

it says 2 things that leave me out of the game
1) visual C 2008 is required
2) an instructor will show you how to.....

i don't want to install visual C

but, this book was clearly written for a classroom environment
i suggest you set it on the shelf - you may be able to use parts of it as reference
but to get started, go with the masm32 package
once you know your way around a little, you will be better equipped to know which parts of the book are usable

That's another edition of this book, which seems better organized.

LE: That;s the practical workbook. My mistake.

blue,

I have both the first and second editions of this book. I thought I had the files for the first edition but I can't locate them anywhere. I do have the files for the second edition, but they are different from the first edition. Sorry.

blue,

Here is how to do your task in MASM32.

Blue.. may I also add - While you're learning, practice thinking in 'little black boxes'.
It take a little while, but training yourself to containerise code into working boxes will help prevent you from smashing your keyboard.
90% of good programming starts on pieces of paper - from there it's 'manual labour' to tap the keyboard for days on end. :green2

Also if you do a good job, about 75% of your filesizes contain informative comments/desciptions - You will forget what you coded a few days ago.
It's nearly impossible to remember all that sh.1t
:wink
