Problem with Memory Addresses and Pointers

[BrettF]

I keep getting this message (sometimes, sometimes not):

_WinAPI_WriteProcessMemory: Only part of a ReadProcessMemory Or

WriteProcessMemory request was completed.

It happens when _MemWrite is called in Memory.au3

Func _MemWrite(ByRef $tMemMap, $pSrce, $pDest = 0, $iSize = 0, $sSrce = "ptr")
    Local $iWritten

    If $pDest = 0 Then $pDest = DllStructGetData($tMemMap, "Mem")
    If $iSize = 0 Then $iSize = DllStructGetData($tMemMap, "Size")
    Return _WinAPI_WriteProcessMemory(DllStructGetData($tMemMap, "hProc"), $pDest, $pSrce, $iSize, $iWritten, $sSrce)
EndFunc   ;==>_MemWrite

Is it my computer, or is there a general problem (I never have memory problems with any other programs)?

It's not meant for external use. Unless you know exactly what your doing, I'd quit now...

It's not me using Memory.au3. It is called from line 671 in GuiRichEdit.au3.

_MemWrite ($struct_MemMap, $TextRange_ptr)

Oh well -- And I donated $3 to Autoit yesterday, as an offering to the gods to try to get an answer.

It might be worth reloading GuiRichEdit.au3 in case something is out of date with it because the one in gafrost's thread has that at line 670 not 671.

And if what Martin said doesn't fix the issue, post a small script which reproduces the problem, not just a snippet of some function which you think causes the problem (because if you need help, that often means your line of thinking isn't correct, otherwise you wouldn't need help to begin with ). That greatly improves chances of getting help. Nothing's 100% guaranteed, but still, better chance.

Since you found the include, I'm surprised you have not seen this from the same thread:

expandcollapse popup

;Include my _Memory() functions
#include <Memory.au3>

;Get the process ID
Global $ProcessID = WinGetProcess("window_name");or however you want to get it

_ReadUsingPointers ()

Func _ReadUsingPointers ()
 
 ;define local variables
 Local $Data, $Pointer_1, $Pointer_2, $Pointer_3
 Local $StaticAddress = 0x6FBCBB60 ;input static address in hex
 Local $Offset1 = 56 ;enter offsets in decimal, not hex
 Local $Offset2 = 200
 Local $Offset3 = 40
 
 ;Open the process
 Local $DllHandle = _MemoryOpen($ProcessID)
 
 ;Read the process
 $Data = _MemoryRead($StaticAddress, $DllHandle)
 
 ;data returned is in decimal and must be combined
 ;with the offset for the next _MemoryRead().
 $Pointer_1 = '0x' & hex($Data + $Offset1)
 
 $Data = _MemoryRead($Pointer_1, $DllHandle)
 
 ;repeat
 $Pointer_2 = '0x' & hex($Data + $Offset2)
 
 $Data = _MemoryRead($Pointer_2, $DllHandle)
 
 ;repeat...
 $Pointer_3 = '0x' & hex($Data + $Offset3)
 
 $Data = _MemoryRead($Pointer_3, $DllHandle)
 ;continue repeating until you get to the desired data
 
 ;can use either way
 ;MsgBox(4096, "Data Read", $Data)
 MsgBox(4096, "Data Read", _MemoryRead($Pointer_3, $DllHandle))
 
 ;Close the process
 _MemoryClose($DllHandle)

EndFunc
