How to Make EndScene Hook work?

[misz]

I have written a little application for gathering information about the character the player is currently playing. And I wanted to hook up to EndScene.

I used the code APoc gave as a example in the WhiteMagic Thread.

The Code Looks like:

using System;
using System.Diagnostics;
using System.Linq;
using System.Runtime.InteropServices;
using System.Windows.Forms;
using WhiteMagic;
namespace WoWInfo
{
publicpartialclassMain : Form,IProcessSelectorNotifier
{
privateProcess WoWProcess;
public Main()
{
InitializeComponent();
Process.EnterDebugMode();
}
privatevoid Main_Load(object sender, EventArgs e)
{
Process[] wowWins = Process.GetProcessesByName("wow");
if (wowWins.Count() == 0)
{
// No wow windows open
MessageBox.Show("Could not find WoW");
Close();
}
else
{
// Open Process Selector
WoWSelector sel = newWoWSelector(wowWins, this);
sel.ShowDialog();
}
}
publicvoid ProcessSelectionComplete(Process proc)
{
// A Async callback of the Process Selector
WoWProcess = proc;
}
// Hook the EndScene
privatevoid button1_Click(object sender, EventArgs e)
{
IntPtr endSceneAddr = DirectX.GetEndScenePointerManaged();
Magic.Instance.Detours.CreateAndApply(Magic.Instance.RegisterDelegate<EndSceneDelegate>(endSceneAddr), EndSceneHandler, "EndScene");
}
[UnmanagedFunctionPointer(CallingConvention.Winapi)]
publicdelegateintEndSceneDelegate(IntPtr instance);
 
privatestaticreadonlyEndSceneDelegate EndSceneHandler = EndScene;
privatestaticint EndScene(IntPtr instance)
{
MessageBox.Show("EndScene");
return (int)Magic.Instance.Detours["EndScene"].CallOriginal(instance);
}
}
}

Everyting works great, except that the EndScene methood never gets called.

Is there some special ASM code i have to inject to make the callback work.

Thank you for all help, misz.

WhiteMagic is for use with injected apps. It's obviously not going to work if you're trying to create a detour to a function that's in an external process.

Stop copy pasting shit you don't understand.
Buy a book.
