Edit: Dur... the variable is working...
MsgBox(4096, "Test", $Write)
Changed to:
MsgBox(4096, "Test", $Write[1])
Displaying properly now.
===== Original post below =====
Having a problem... Thanks to DrJohn20 for putting a tutorial up that I've been using to learn NomadMemory with CE.
I'm having a really hard time with this one though... See bottom for picture of the pointer I'm trying to read from in AutoIt, and the full code.
I can't seem to get the pointer to read correctly. "$FinalAddress" is calculating correctly, now I'm wondering if there isn't something wrong with the offsets calculating.
| Code: | ;Calculate and Write
Local $Offset[6]
$Offset[0] = 0
$Offset[1] = Dec("B4")
$Offset[2] = Dec("A8")
$Offset[3] = Dec("A4")
$Offset[4] = Dec("120")
$Offset[5] = Dec("0") |
Reversed order.. see picture. [0] is always 0.
| Code: | $StaticOffset = Dec("1C60EE8") - Dec($BaseAddress)
$FinalAddress = "0x" & Hex(Dec($BaseAddress) + $StaticOffset) |
This is calculating properly. I'm getting the same address for $FinalAddress as the address of the first pointer.
| Code: | $Write = _MemoryPointerRead($FinalAddress, $hMemory, $Offset)
;$Write = _MemoryRead("0x20A1C760", $hMemory, "wchar[10]")
MsgBox(4096, "Test", $FinalAddress)
MsgBox(4096, "Test", $Write) |
Just to make sure all the code was working right, I did a read on the address my pointer is pointing to (as you can see, it's commented out) and it's returning the value I'm looking for. So that's not the problem. (Ignore the $write variable name, I never changed it to read)
The problem (I think) is the _MemoryPointerRead and the offsets. I just cannot figure out why it's returning blank. Anybody have any idea?
