I have made C# exe trainers that use ReadProcessMemory and WriteProcessMemory, but now I want to make a dll trainer in C#. how would I read/write and would I need to make an injector? any help would be appreciated.

Managed DLLs do not load/work the same as native ones. You can't just inject a managed DLL into a process and have it work. You need to first load the .NET framework into the process then have the process load your DLL and create an instance of the main object it is exposing.

It's known as CLR hosting, there is an old guide on how to do it here:

I could give you a hand tomorrow when im able to function properly.
I can't remember if i'v made a full memory class for dll's but it wouldn't take long too.

I'll sort you out with my injector aswell. Basically does what Wiccaan mentioned besides it doesnt use a C++ dll.

A simple example of a c#/vb dll
Code:
using System;
using System.Windows.Forms;
using System.Threading;
namespace CDll
{
    public class Class1
    {
        public static int DllMain(String arg)
        {
            new Thread(Main).Start();
            return 0;
        }

        static void Main()
        {
            MessageBox.Show("C# Dll Injected");
        }
    }
}

Code:
Public Class Class1

    Public Shared Function DllMain(ByVal arg As String) As Integer
        Dim _Thread As System.Threading.Thread = New System.Threading.Thread(AddressOf Main)
        _Thread.Start()
        Return 0
    End Function

    Shared Sub Main()
        MsgBox("VB Dll Injected")
    End Sub

End Class


And they'l inject just fine


I had to do this awhile back when i wanted to make a trainer for an xtrap protected game. Worked just fine.

@Wiccaan thanks that tut was very informative. But if I can keep with c# i will. If not I'll Definitely give that tut a try.

@Pingo that would be great! can't wait to see how the injection works Very Happy
