Might want to look at how your calling your function MemWrite() << it has 4 parameters, then you use Call("MemWrite") with no parameters

Edit:

Typo

yea, looks like $dll isn't set ....

[sd333221]

Cant i declare the parameters before i call the function?

$Adress = "0185C465"
$DataToWrite = "C605F955860101"
$DataSize= "7"

Call("MemWrite")

[sd333221]

Yes, but what may i choose as the $dll is this the target?

I just want the target to be "Diablo II.exe".

Can you recommend me an other writetomem script?

Call("MemWrite")

You would need to declare them in the Function itself... then just do a call to it like MemWrite() rather than Call("MemWrite")

Example:

Func MemWrite($ProcessName = "Actual Processes name", $Address = "0185C465", $DataToWrite = "C605F955860101", $DataSize = "9")

That way all the parameters are optional because the are pre-defined.

thank you, i try this now

I couldn't find anywhere where this WriteMemLoc is located and or what DLL it uses. I know that w0uters Mem functions uses the kernel32.dll but this wasn't on MSDN site as a function.

[sd333221]

this is w0uters mem function

Func _MemWrite($ah_Mem, $i_Address, $v_Inject)
    Local $av_Call = DllCall($ah_Mem[0], 'int', 'WriteProcessMemory', 'int', $ah_Mem[1], 'int', $i_Address, 'ptr', DllStructGetPtr($v_Inject), 'int', DllStructGetSize($v_Inject), 'int', '')
    Return $av_Call[0]
EndFunc ;==>_MemWrite

but i dont know how to use the parameters :;(

could you make an example with:

file: Winesweeper.exe

adress: 0185C465

bytes: C605F955860101

size: 7

just to explain?

same error, the MemWrite function is corrupted i think

where did you specify $dll ? so what do you expect... magic ?

[sd333221]

where did you specify $dll ? so what do you expect... magic ?

what $dll do i have to use? i want to edit the memory of my .exe file not an dll!

[SmOke_N]

what $dll do i have to use? i want to edit the memory of my .exe file not an dll!

He's saying this.

1. You have a variable named $dll that is undefined

2. You are using DLLCall() with No DLL, because $dll is undefined.

i suggest you take a good look at my _mem udf and figure out how it works.

i suggest you take a good look at my _mem udf and figure out how it works.

Look in his signature for the _mem udf. Also, you don't have to "Call" a function like that in AutoIt, you can simply type the function name, like this:

Function ()

and if it requires parameters:

Function (parameter1, parameter2, etc...)

If you read wOuter's _mem udf topic and are still having trouble even though you know everything is being done correctly, you may need to alter his functions to suit your needs. They are not set to read and write every conceivable thing that can be read and written to memory. You may need to specify DWORD, or CHAR, etc.. depending on what you are doing. You also may need to specify a few other different parameters.
