| i don't code in c# so not sure about the first question but the second one, yes that declares an array of size 2 with byte elements each of value 0x90 which is 2 NOPs. at least if the array declarations are the same as in c++.

huh?
Found on cef this

 don't expect to do this without learning anything
You'll have to learn C++. And I'm not talking about just learning a bit of it cause you won't get anywhere.
If you want to use C# then like he said use WriteProcessMemory. did you even attempt to search it?

i'm not much of a C# guy but try something like this.
byte[] hack_on = { 0x0F, 0x84 };
byte[] hack_off = { 0x0F, 0x85 };
if(!mypatch)
{
writeProcessmemory(handle, address, hack_on, 2,0);
mypatch = 1;
}
else
{
writeProcessmemory(handle,address,hack_off,2,0);
mypatch =0;
}
as for inline asm, while C# doesn't normally have support for it their
are somewhat decent alternatives such as shynds blackmagic library

| why don't you write a dll in C++, the use inline asm to make you're script and then import that function into your C# project?

| Just write the bytes directly with WriteProcessMemory, same result.

ok so
| Code: | private void button1_Click(object sender, EventArgs e)
{
IntPtr bytesout;
byte[] NewVal = { 0x90 };
return WriteProcessMemory(ProcessHandle, (IntPtr)0x0001337 , NewVal, (UIntPtr)NewVal.Length, out bytesout);
} |
give error
| Quote: | | Since 'simpleTrainer.Form1.button1_Click(object, System.EventArgs)' returns void, a return keyword must not be followed by an object expression |
---edit---
when i delete return , error dissapear , can it be without return?

read the error, it tells you exactly what's wrong.
get rid of the return.

ok no errors, my button looks that:
| Code: | private void button1_Click(object sender, EventArgs e)
{
WindowHandle = FindWindow("MapleStoryClass", "MapleStory");
GetWindowThreadProcessId(WindowHandle, out ProcID);
IntPtr bytesout;
ProcessHandle = OpenProcess(0x1F0FFF, 1, ProcID);
byte[] NewVal = { 0x90 };
WriteProcessMemory(ProcessHandle, (IntPtr)0x0001337 , NewVal, (UIntPtr)NewVal.Length, out bytesout);
} |
this example should nop adress 00001337 ?

You used FindWindow with both the Class and the Window ... ,
use just the class.
Remember though, you need to nop ALL the bytes in that address.
And yes, it will work in case 0x000001337 exists.
