Hi Ramon...
I'm having a weird problem here...
System = Win7 Pro, Service Pack = 1..something!
The data is written to the file OK, but the data counter (ECX [or EDX]) is being corrupted on the stack therefore the loop hangs.
EBX is fine.
I use the RegVal macro as quick look at registers, so don't think it's this as it's always worked fine.
FillBuffer - fills the array with zeros
It's in this code, as nothing else is happening at this point, so we're looking at a couple scenarios..
WinAPI, or WriteTextLine is corrupting the stack ?
Finally how does on set your stacksize in EC ?
Thanks
Van

Hang on a bit... I think I might be me.. :shock:
don't tell anybody... :t
Resolved.. it.
After every instruction, I placed a RegVal ecx macro.. and it
- Corrupted on FillBuffer, commented this out..
- Even corrupted on MemFill..
- Then corrupted on SendMessage.. commented this out
- Corrupted on Write line.... ??
WTF...Now I'm beginning to freak out.
Closed EC restarted and changed my FillBuffer proc and manually implemented epilogues and prologues.
Worked on Fillbuffer.. then SendMessage then Writeline... Farrrk!! So got rid of all the RegVals and now all is fine.
It's not the closing/restarting of EC as I've done this at least 50x while looking for this solution...
.. and the solution is... I don't know... it just works so my hands are off
:badgrin:

What is this RegVal macro supposed to do, and where did you get it?
Hi Van,
Glad you could solve the problem!

Good question!

Just a quickie/speed debugging macro I made up, to display a register value of interest.
It's in the code section on the first post.
RegVal MACRO reg:REQ
push reg
invoke FillBuffer, ADDR DebugSz, 256, 0
pop reg
push reg
invoke dwtoa, reg, ADDR DebugSz
invoke MessageBox, GlobWnd, ADDR DebugSz,TextAddr("REG VAL"), MB_OK
pop reg
ENDM
From what I see, RegVal ecx will trash eax and edx but otherwise it should be OK.
EDX.. thanks I've overlooked this... :icon14:
