Hello all,
i need to use the function ExpandEnvironmentStringsA in nasm to use shourtcuts such as %appdata% and %tmp% .. etc.
i tried an example on the internet but it wont running and give errors, i think the problem with parameters.
can i find complete illustrated example about using this function...
thanks alot !
Post the code that throws errors, and the errors themselves, and we'll see if we can help you.
pretty simple function
more than likely, the destination buffer is too small
the return value tells you the size of the required buffer
jmp GetFilePAth
FilePAthReturn:
pop ecx
xor Eax,Eax
Push Eax
Push ebx
Push ecx
;Call ExpandEnvironmentStringsA
call [ebp+0x10]
GetFilePAth:
call FilePAthReturn
db "%appdata%\xxx.xx"
db 0x00
this is code don't work correctly
thanks alot !
That it doesn't work is a big surprise indeed :eusa_boohoo:
;Call ExpandEnvironmentStringsA
call [ebp+0x10]
What is that, an attempt to cheat the AV brigade?
GetFilePAth:
What's your error message on that, "symbol not found"?
call FilePAthReturn
db "%appdata%\xxx.xx"
So Nasm knows by some magic that these two lines are in different segments?
Where did you copy that code from? Or do you pretend it's your own, and you understand what you are doing??
