I want to use executeCodeEx to call setwindowstext, how to write code?

For example, mouse_event can't be used? These 5 parameters? He said up to 4 parameters?

Dark Byte · Posted: Wed Apr 03, 2019 11:01 pm Post subject:

correct, but then again, most of the common functions already have a celua implementation (like mouse_event)

Try a different process not CE

What if we need to use __fastcall calling convention? It seems that executeCodeEx can only use stdcall or cdecl calling conventions.

Dark Byte · Posted: Thu Mar 02, 2023 3:16 pm Post subject:

for custom types of calling conventions you'll have to write a wrapper using auto assembler or C that converts the provided parameters to the required calling mechanism

e.g: call for a 2 param __fastcall call it like a 2 param stdcall

IDA disassembler determined it to be a fastcall function, it uses the registers ECX, EDX, R8, R9.

Dark Byte · Posted: Thu Mar 02, 2023 3:56 pm Post subject:

r8 and r9? So it's 64-bit?

In that case it's normal 64-bit calling abi. You can pick whatever calling convention, it won't affect the result

Thank you so much Dark Byte, this is saving me so much time now that I can call functions for testing within cheat engine. <3
