new to asm (simple question)

[Mark Jones]

   .if eax==WM_INITDIALOG
         invoke  GetDlgItem,hWin,chkTurns  ; CheckBox0
         mov hChkTurns, eax

...It gives an error on the bold line. It gives no description just the error number A2001.
chkTurns is declared (chkTurns equ 1001), hChkTurns is declared (hChkTurns equ 0)

I have no idea what is wrong. Also, where can I find out what the error numbers mean? I am using RadASM with MASM.

Hi Troy,

Take things one step at a time. MASM error descriptions are read from a file (ML.ERR) located in \masm32\bin. If that file is missing, any errors reported will not contain descriptions. (The first time I installed MASM32 mine disappeared somewhow...) :lol

As for your mov hChkTurns, eax, consider what you're trying to do here. EAX is a DWORD register (4 bytes) and you're tring to move that into a STATIC value declared with EQU. For this instruction to work you'll need to supply four non-static bytes at a memory offset. What Ossa said above reserves a DWORD (DD, 4 bytes), initalized to zero, at the physical memory offset "hChkTurns." Never give up! :U

ok, i see that now. I changed the equ to dd and it will run but gives a compile warning. Also the msgbox still never appears and the close button on my form does not work. I had to end the process manually.

I have attached the project as a sort of last resort. Thank you.

Okay Troy, I'll help. I don't know what "Oasis" is, but note that the discussion of any sort of program which violates a software license agreement is forbidden here. Your code includes a "poke" routine and a "nopit" value and others which are indicative of tampering with another program... if that is the case this topic may be locked and/or deleted. Fair warning!

I changed the EQU to DD and it will run but gives a compile warning.

You did change "EQU" to "DD", but the "DD" was still under a .CONST directive. :wink

Constants go under .CONST, data under .DATA or .DATA?, and code under .CODE sections. The "." directives supercede all other directives and datatypes.

You don't technically need an .inc file. You could delete that file and replace the top of the main file with this:

Code Select Expand


include masm32rt.inc       ; MASM32 v9.0 compile-time libs and standard options
comment * unused:
include shell32.inc
includelib shell32.lib *

DlgProc     PROTO   :HWND,:UINT,:WPARAM,:LPARAM
Poke        PROTO   :DWORD,:DWORD,:BYTE

; Constants only!
.const
IDD_DIALOG1         equ 101
chkTurns            equ 1001
chkFollowers        equ 1002
chkScarab           equ 1003

; Initialized (preset) Data
.data
wnd_name            db  'Oasis',0
cls_name            db  'Oasis',0
rew                 db  'This Stuff Is Hard!',0
nopit               db  090h,090h,090h
aTurns              dd  041825Eh
uTurns              db  004h,050h,089h

; Unitialized (zeroed) Data
.data?
hInstance           dd  ?
hChkTurns           dd  ?

.code
start:


As an optimization tip, notice that "wnd_name" and "cls_name" have the same values. If both of these do not change, remove one of them.

As for all the other issues,

    ;mov eax,uMsg

This is causing a big problem. When Windows sends messages to your WndProc, the message (a DWORD) is passed as "uMsg" so here this value is never getting into EAX and therefore no messages are ever being retrieved and processed! :U

[Troy Lundin]

Well, as to your first comment. That is the reason I had never posted my project.

As to ;mov eax,uMsg: I uncommented it and it all worked fine. That makes it even more irritating that this was such a simple solution.
Thank you for your continued help.

Mark,
apparantly he's trying to write a trainer for the game called "Oasis", available here:http://www.oasisgame.com/
