Memoryread String

Recommended Posts

hendrikhe

I am trying to read a String from an Address, but it seems more difficult than I thought. Even with the right address the MsgBox doenst show the right Value of my String, it shows the Address in Assigned Long but not the right String Value.

The String even beeing a number between 1 and 100 is a String in ASCII.

The Address of the String is 0x011683F0 and the current value of my string is 94

My Code

#include <Array.au3>
#include <NomadMemory.au3>

$ID=_MemoryOpen(ProcessExists("Tutorial.exe"))
$Address=0x011683F0
$Res = _MemoryRead($Address,$ID)

MsgBox(0,"","Value " & $Res)
MsgBox(0,"","Value " & Hex($Res))
MsgBox(0,"","Value " & Dec($Res))
MsgBox(0,"","Value " & Dec(Hex($Res)))
_MemoryClose($ID)

My results for the MsgBox:

13369

00003439

13369

78697

But it doesnt show the real value 94, maybe I need to do something like that ConvertValueToString($Res), but I dont know the right command.

If you want to read a string then you must set the last parameter in _MemoryRead to "char" as documented in NomadMemory.

EDIT:

Looks like you have the correct address because the return by default id a dword and

00003439 = ascii values for 49, which would be read as 94 for a string.
