MCode Tutorial (Compiled Code in AHK)

[tic]

Which compiler are you using? I was just wanting to test this application so downloaded

x86_64-w64-mingw32-gcc-4.9.2.exe

I use an assembly compiler for all tasks I'm doing in MCode.
Its not quite comfortable but useable.

3. an MCode Function:
I use this one:

Code: Select all

MCode(mcode)
{
  static e := {1:4, 2:1}, c := (A_PtrSize=8) ? "x64" : "x86"
  if (!regexmatch(mcode, "^([0-9]+),(" c ":|.*?," c ":)([^,]+)", m))
    return
  if (!DllCall("crypt32\CryptStringToBinary", "str", m3, "uint", 0, "uint", e[m1], "ptr", 0, "uint*", s, "ptr", 0, "ptr", 0))
    return
  p := DllCall("GlobalAlloc", "uint", 0, "ptr", s, "ptr")
  if (c="x64")
    DllCall("VirtualProtect", "ptr", p, "ptr", s, "uint", 0x40, "uint*", op)
  if (DllCall("crypt32\CryptStringToBinary", "str", m3, "uint", 0, "uint", e[m1], "ptr", p, "uint*", s, "ptr", 0, "ptr", 0))
    return p
  DllCall("GlobalFree", "ptr", p)
}

are you sure VirtualProtect is only needed on AHKx64?

Hi all,

I am a bit new to MCODE, but I have managed to install compiler TDM-GCC-64\bin\gcc.exe and was able to generate MCODE. However, I have been searching for at least couple hours but can't find a way to set compiler to generate MCODE encoding in hexadecimal vs base64(the default). The function is writeen in C.
Any help is appreciated, thank you.

Someone helped me.. thank you..
You have to change it under "Settings" here :
"Laszlo Style" for Hex
"Bentschi Style" for Base64

[nnnik]

Which compiler did you use? Also why do you want to use Hex instead of base64?

What does 1 or 2 stand for before x64/x86? I've seen machine codes using these. For example, in this one : " 2,x86:aipYww==,x64:uCoAAADD ".

Thank you.

its stupid way of passing CRYPT_STRING_HEX(1) / CRYPT_STRING_BASE64(2) to CryptStringToBinary(), depending on whose mcode functions ure using

[robodesign]

Thank you.... So, if it's bentschi mode /edition , it's in base 64, right ?

[swagfag]

i dont know what betchis looks like
in the one 3 posts above me, yes.

just follow the code

[joedf]

Yes, base64.
