試圖掛鉤的DoDragDrop資源管理器，但委託方法並沒有叫

Question

「OLE32」，「的DoDragDrop」功能掛鉤的探險家是 成功，但每當我在資源管理器將文件拖到我的 DoDragDropHook功能是不是打電話，是新的鉤的概念，我想從過去3個月，但到現在沒有 正確的結果。請幫我我要去哪裏錯了

namespace DragDrop_DLL 
{ 
    public class Main : EasyHook.IEntryPoint 
    {  

     DragDrop_Console.RemoteMon Interface;   

     public LocalHook dragDropHook; 

     public Main(RemoteHooking.IContext InContext, String InChannelName) 
     { 
      try 
      { 
       Interface = RemoteHooking.IpcConnectClient<DragDrop_Console.RemoteMon>(InChannelName); 

       File.AppendAllText(@"F:\DragDropLog.txt", "Main : Channel Name passed" + Environment.NewLine); 
      } 
      catch (Exception ex) 
      { 
       Interface.ErrorHandle(ex); 

       File.AppendAllText(@"F:\DragDropLog.txt", "Main Exception :"+ ex.ToString() + Environment.NewLine); 
      } 

     } 

     public void Run(RemoteHooking.IContext InContext, String InChannelName) 
     { 
      try 
      { 
       dragDropHook = LocalHook.Create(LocalHook.GetProcAddress("Ole32.dll", "DoDragDrop"), new DragDropDelegate(DoDragDropHook), null); 


       dragDropHook.ThreadACL.SetInclusiveACL(new Int32[] { 0 }); 
       //Also tried with setExclusiveACL 
       //dragDropHook.ThreadACL.SetExclusiveACL(new Int32[] { 0 }); 
       File.AppendAllText(@"F:\DragDropLog.txt", "Run : LocalHook Created" + Environment.NewLine); 
      } 
      catch (Exception ex) 
      { 
       Interface.ErrorHandle(ex); 

       File.AppendAllText(@"F:\DragDropLog.txt", "Run Exception :" + ex.ToString() + Environment.NewLine); 

       return; 
      } 

      Interface.IsInstalled(RemoteHooking.GetCurrentProcessId()); 

      RemoteHooking.WakeUpProcess(); 

      while (true) 
      { 
       Thread.Sleep(1000);       
      } 
     }  

     [DllImport("Ole32.dll",CharSet=CharSet.Unicode,SetLastError =true,CallingConvention =CallingConvention.StdCall)] 
     static extern int DoDragDrop(
      IDataObject pDataObj, 
      IDropSource pDropSource, 
      UInt32 dwOKEffects, 
      UInt32[] pdwEffect); 

     [UnmanagedFunctionPointer(CallingConvention.StdCall,CharSet =CharSet.Ansi, SetLastError = true)] 
     [return: MarshalAs(UnmanagedType.I4)] 
     delegate int DragDropDelegate(
      IDataObject pDataObj, 
      IDropSource pDropSource, 
      UInt32 dwOKEffects, 
      UInt32[] pdwEffect); 

     static int DoDragDropHook(
      IDataObject pDataObj, 
      IDropSource pDropSource, 
      UInt32 dwOKEffects, 
      UInt32[] pdwEffect) 
     { 
      try 
      { 
       ((Main)HookRuntimeInfo.Callback).Interface.GotDragFileObject(pDataObj); 

       File.AppendAllText(@"F:\DragDropLog.txt", "DoDragDrop Hit :" + pDataObj.ToString() + Environment.NewLine); 

      } 
      catch(Exception ex) 
      { 
       File.AppendAllText(@"F:\DragDropLog.txt", "DoDragDropHook Exception :" + ex.ToString() + Environment.NewLine); 
      } 

      return DoDragDrop(pDataObj, pDropSource, dwOKEffects, pdwEffect); 
     } 
    } 

    internal interface IDropSource 
    { 
    }  

}

這是一個僞代碼：

private void CanvasLP_Drop(object sender, DragEventArgs e) 
    { 
     if (e.Handled == false) 
     { 
      Thumb thumb = (Thumb)e.Data.GetData("Object"); 
      //thumb is used to store the dropped item, as in my case it is of type Thumb 
      //Object here is the item being dragged 
      //You can get file path from file name by using: 
      //Path.Combine(Directory.GetCurrentDirectory(), filename) 

     } 
    }
