please help with aob scan on c++.
I need to scan dynamic memory.
I need to combine FindPattern + VirtualQuery , how to do it???

Code:
DWORD FindPattern(DWORD dwAddress,DWORD dwLen,BYTE *bMask,char * szMask)
{
   for(DWORD i=0; i<dwLen; i++)
      if (bCompare((BYTE*)(dwAddress+i),bMask,szMask)) 
         return (DWORD)(dwAddress+i);
   return 0;
}

Code:

MEMORY_BASIC_INFORMATION mbi;
        VirtualQuery( ( void* )pvAddress, &mbi, sizeof( mbi ) );


PLEASE HELP , VERY NEED.

You need to loop VitualQuery and step the page sizes that are currently accessible to you.

I'm not going to hand you the code because you obviously don't know what you are doing already. Look at the MSDN page regarding VitualQuery, it explains the purpose of the API and the parameters needed to call it.

Use Google if you need to find further help. Begging isn't going to help you learn anything.

Here is what I do:
Code:

function FindPattern(pattern,sig:string;startaddress,stopaddress,index:dword):dword;
var
MBI:MEMORY_BASIC_INFORMATION;
p,i,z,k,m,nindex,nsize:dword;
rzsig:array of byte;
begin
nindex:=0;
Result:=0;
if odd(length(sig)) then exit;
SetLength(rzsig,length(pattern));
p:=length(sig);
i:=0;
z:=1;
repeat
if pattern[i+1]='?' then
rzsig[i]:=0
else
rzsig[i]:=strtoint('$'+sig[z]+sig[z+1]);
inc(i);
inc(z,2);
dec(p,2);
until p=0;

z:=length(pattern);
while(VirtualQuery(ptr(startaddress),MBI,sizeof(MBI))=SizeOf(MBI)) do begin
if startaddress>=stopaddress then break;
p:=MBI.Protect;
if not ((p=PAGE_READWRITE)or(p=PAGE_EXECUTE_READWRITE)or(p=PAGE_READONLY)or(p=PAGE_EXECUTE_READ)) then begin
inc(startaddress,MBI.RegionSize);
Continue;
end;
m:=dword(MBI.BaseAddress);
if MBI.RegionSize=0 then Continue;
if z>MBI.RegionSize then Continue;
nsize:=(MBI.RegionSize-z)+1;
p:=0;
if m>=z then
repeat
k:=pbyte(m+p)^;
if rzsig[0]=k then begin
i:=1;
repeat
if pattern[i+1]='?' then begin
inc(i);
Continue;
end;
k:=pbyte(m+p+I)^;
if not (k=rzsig[i]) then break;
inc(i);
until i=z;
if i=z then begin
if nindex=index then begin
Result:=m+p;
exit;
end
else
inc(nindex);
end;

end;

inc(p);
until p=nsize;
inc(startaddress,mbi.RegionSize);
end;


end;

yeah I know,messy.

Rather than waiting for someone to pity you, why don't you spend this time learning how to read MSDN?

We're not going to help someone who won't put in any of his/her own effort.

And that's Pascal, not AA.

I do not expect there is no way I can help in another forum, if I could, I'd make the code itself.
Pascal I have never seen ...
