 |
|
Heey guys,
Little question, long answer:P
How to find a array of byte in delphi with readprocessmemory?
I need to find: 01 00 00 00 00 73 74 65 72 2F
How to do this:P
Grtz,
Niels

already got it:
| Code: | procedure TForm1.Button1Click(Sender: TObject);
var
test: byte;
test2: variant;
a,b: integer;
begin
for a:=978893079 to 978893279 do
begin
ReadProcessMemory(PHandle,Pointer(a),@test,1,Read);
test2:= 00;
if (test = test2) then
begin
ReadProcessMemory(PHandle,Pointer(a+1),@test,1,Read);
if (test = test2) then
begin
ReadProcessMemory(PHandle,Pointer(a+3),@test,1,Read);
if (test = test2) then
begin
ReadProcessMemory(PHandle,Pointer(a+4),@test,1,Read);
if (test = test2) then
begin
test2:= 115;
ReadProcessMemory(PHandle,Pointer(a+5),@test,1,Read);
if (test = test2) then
begin
test2:= 116;
ReadProcessMemory(PHandle,Pointer(a+6),@test,1,Read);
if (test = test2) then
begin
test2:= 101;
ReadProcessMemory(PHandle,Pointer(a+7),@test,1,Read);
if (test = test2) then
begin
test2:= 114;
ReadProcessMemory(PHandle,Pointer(a+8),@test,1,Read);
if (test = test2) then
begin
test2:= 47;
ReadProcessMemory(PHandle,Pointer(a+9),@test,1,Read);
if (test = test2) then
begin
b:=a;
metinsteen:=a;
end;
end;
end;
end;
end;
end;
end;
end;
end;
end;
ShowMessage('found');
ShowMessage(inttostr(b));
end; |
bit vrapy but t works:P
didn't know it works that fast in delphi, thougt it would be much slower because it isn't asm
//edit
hmm not so fast as i thougt. i need to scan a bigger area, than it is very slow.

it compiles to asm, fyi.
and why are you doing a billion single byte reads |

| hmm, read the array length worth of bytes from an address, then compare what you got to the original with CompareMem |

i don't really know what you mean
//edit
hmm i now know how to use comparemem, but i don't know how to read a larger area.
//edit2
i found a few things but don't know how to use them.
copymem
getprop
how do i copy the memory of an other app?

you don't unless you've injected a dll.
just read a chunk with ReadProcessMemory |

how to read a large area with readprocessmemory?
if i read about 8bytes then the first byte is 1 and all other bytes are zero

http://msdn.microsoft.com/en-us/library/ms680553%28VS.85%29.aspx
BOOL WINAPI ReadProcessMemory(
__in HANDLE hProcess,
__in LPCVOID lpBaseAddress,
__out LPVOID lpBuffer,
__in SIZE_T nSize,
__out SIZE_T *lpNumberOfBytesRead
);
nSize [in]
The number of bytes to be read from the specified process. |

you where right, this moring i tryed again reading more bytes. this time i worked.

thank you very much.

Keep in mind when you are reading from another processes memory:
| Quote: |
The entire area to be read must be accessible, and if it is not accessible, the function fails.
|
So just setting nSize to 1,000,000 has high potential to fail. Use VirtualQueryEx to get page size and information and read based on that instead for a more secure method.
