menu output to console

[Xor Stance]

I tried my best to read the Win32API reference, I suggest to add "MG_OK". Can you guys help me please?

Is it on the includes? or might I need to include it? It sounded kind like a joke but it's serious too.
I mean that I needed to put as a constant the menus but I need to define a variable as a integer, then after he types his name.
Since I'm not quite familiar with masm syntax, somehow how should it be. I'm trying my best! and the include files I read, I somehow
understand some but it's too complicated on how to use it, I wanted to learn first from console then later to Windows; just I kinda
suck on this stuff, I haven't take that much time but I know from console will be fast.

I cannot tell what you are trying to do with this code. When I attempt to assemble it, as posted, I get 13 errors.

Code Select Expand


C:\masm32\My\_TRY\xor.asm(19) : error A2008: syntax error : name
C:\masm32\My\_TRY\xor.asm(20) : error A2008: syntax error : age

The problem code is:

Code Select Expand


(19) IDM_NAME "name" equ 1
(20) IDM_MENU "age" equ 2


The proper syntax for EQU is:

symbol EQU expression

The symbol must be a unique name. The expression can be an integer, a constant expression, a one- or two- character string constant (four-character on the 80386/80486), or an expression that evaluates to an address.

C:\masm32\My\_TRY\xor.asm(42) : error A2108: use of register assumed to ERROR

These errors are a side effect of the missing .CODE directive the should precede Start.

C:\masm32\My\_TRY\xor.asm(40) : error A2006: undefined symbol : StdIn

These errors are because your includes do not include:
include \masm32\include\masm32.inc
includelib \masm32\lib\masm32.lib

Code Select Expand


C:\masm32\My\_TRY\xor.asm(27) : error A2111: conflicting parameter definition

This error is because you WinMain procedure declaration does not match the prototype.

Code Select Expand


C:\masm32\My\_TRY\xor.asm(43) : fatal error A1011: directive must be in control block

And this error is due to a misplaced .ELSE.

When you solve these problems, you will uncover some additional errors, but they are essentially more of the same.

You might take a look at the example Vortex posted here:

Hi,
   You haven't included masm32.inc and masm32.lib to use StdOut. Are you using a GUI app or is it linked as a console app. If it is a console app it cannot usually have a window or a menu. If it is a GUI App, you need to get a console first using AllocConsole.

I got tire for now, what I wanted that the user displays to elect "name or age" after that if he/she inputs name he will have to put his name,
I fix some but them I got more than I do.

Does masm supports most Win32API? So I founded new things like "GetStdHandle" in console apps. I know that some like declaring the numbers
of byte it's not necessary how the Win32API tells it. 

[thomasantony]

Hi,
 Understand what your code does before posting it ::) . You don't have a window then why do you have a WndProc? Who will set the values of wParam? ::) . Read Iczelion's tuts first. I will give some pointers on your problem.
1. Display a list like :
 A. Name
 B. Age
 Choose:
2. Use Stdin
3. Check if input is 'A', then display question and get name from user else do the stpes to get the age

BTW, StdOut calls GetStdHandle and then WriteFile. As of the numbers use the constants in windows.inc

I just forgot about WndProc and and wParam, the thing is that does it requires the command line in console? I knew that it was code from the windows and I thought some instructions could be use in the console. When I declare before I declare .IF which instruction should be use if it's
in Eax register? mov eax,wParam was before, I guess it will be move the 16-bits on eax?

mov eax,ax
What are you trying to do? Move value in 16bit register to a 32bit register? If so, use movzx or movsx and not mov.

.IF NAME=='A'

.ELSEIF ax==AGE

.ELSE

stpes==AGE


NAME is a constant.

Hi,
   Here is a piece of code

; do all the includes and data etc.
.data

Thanks everyone!  :U

Xor,
your code shows that you do not understand some of the fundamentals of programming, let alone understand asm. I would suggest that you learn some basics (like string comparison) before doing any more, you can't solve more complex bugs when your code is full of simple ones.
