registers as pointer q

Go back six years: fat exe but no source

Yes, I saw that also.

Still waiting for dc's reply. I will close this thread unless dc can furnish his source code.


Edit to add:  Thank you... for posting your project below.

Ok. Thanks. Where in the code are you having the issues?
Post that snippet... now we know where it comes from.

jj2007, dc, I have removed a couple posts above to tidy up

And dc, I apologize for all the scrutiny.

We are almost there:
Cannot open file: "dxbase.def"

dxfunc.inc(12) : fatal error A1000: cannot open file : dxbase.def
Press any key to continue . . .
where is dxbase.def -- ??
btw, the project looks pretty impressive.    A good candidate for the Game Development board.
I will leave it to the assembly gurus to assist you from here.  Thank you for posting your code.

ooops... it might need all the direct x defs to work. ill experiment and see... maybe only the one is needed

You can just zip those and post them here. No need to reupload the entire project again.

Hi dc,

When trying to build your project, I got many error messages. With minor modifications to four files, all attached, I got it running, though - with UAsm but not with ML:

Code Select Expand

cannot open file : oaidl.inc
cannot open file : olectl.inc
If your project built without errors on your machine, there are two possible reasons:
1. You have an old version of the Masm32 SDK
2. You changed include files of the Masm32 SDK

If the version is old, get the latest one (if \Masm32\include\windows.inc is of 10 Jan 2012 and has 977,412 bytes, you got the latest one).

Under no circumstances, never, should you change the original Masm32 SDK files, for a very simple reason: doing that, your code becomes incompatible with the SDK, and nobody can help you. It is a hundred times better to adapt your sources to the SDK than the other way round!

The exe works, it looks like a big game, compliments

Now it's time to explain where you see problems to solve: file name, line number, and three lines of code, please, so that we can check what's needed.

im gonna have to assume that a pointer and an index are not used together at all in ml... please prove me wrong...
thanx

mov eax, somevar[ecx]

Proved wrong

[NoCforMe]

Hmm, JJ: not to split hairs here or anything but isn't

Code Select Expand

    MOV    EAX, somevar[ECX]

an example of an index (ECX) only? Where's the pointer? I'm assuming that somevar is an array, with ECX indexing into it, right?

How about this--would you say this shows both a pointer (EBX) and an index (ESI)?

Code Select Expand

LEA EBX, somevar
MOV ESI, indexVal
MOV EAX, [EBX + ESI]

Anyhow, to the OP: Why so much confusion in your mind between pointers and indices? Can you give us a better clue as to where exactly you're having trouble understanding this concept? I know it's not trivial, and trips up a lot of beginners, but at the same time it ain't rocket science ...

Code Select Expand

    LEA    EBX, somevar
    MOV    ESI, indexVal
    MOV    EAX, [EBX + ESI]


If you store dwords usually must be:

Code Select Expand

    LEA    EBX, somevar
    MOV    ESI, index
    MOV    EAX, [EBX + ESI*4]

i get pointer 'pArray' from globalAlocate
then try to access it like:

Code Select Expand

mov esi,index
shl esi,2
mov eax,pArray
bt [eax+esi],0
jc @f
i get errors in assembly
ive tried:

Code Select Expand

bt [eax][esi],0

bt dword ptr eax[esi],0

bt dword ptr pArray[esi]
if anything assembles without error it isn't the allocated memory being accessed...

Interesting
