how do i use these both together?

i can't seem to get it working

code:

---

function OnEvent_Initialize(){
var Wnd = MsgPlus.CreateWnd("windows.xml","dragdrop");
Wnd.RegisterMessageNotification(WM_DROPFILES);
Interop.Call("shell32","DragAcceptFiles",Wnd.handle,true);
}

function OndragdropEvent_MessageNotification(PlusWnd, Message){
switch(Message){
case WM_DROPFILES:
Debug.Trace(Interop.Call("shell32","DragQueryFile",0,0xFFFFFFFF,null,0));
break;
}
}

Here you go sir!

code:

---

var WM_DROPFILES = 0x233;
function OnEvent_Initialize() {
   var Wnd = MsgPlus.CreateWnd("Windows.xml","dragdrop");
   Interop.Call("shell32", "DragAcceptFiles", Wnd.handle, true);
   Wnd.RegisterMessageNotification(WM_DROPFILES, true);
}
function OndragdropEvent_MessageNotification(PlusWnd, Message, wParam, lParam){
   switch(Message){
      case WM_DROPFILES:
         //Set some variables
         var MAX_PATH = 260; //Maximum characters in a path
         var lpszFile = Interop.Allocate((MAX_PATH+1)*2); //File name buffer
         var arrFiles = new Array(); //Array to store the files in
         //Get the files count
         var nFilesCount = Interop.Call("shell32", "DragQueryFileW", wParam, 0xFFFFFFFF, 0, 0); //wParam is a handle to the dropped files
         //Loop through the files
         for(var i=0; i<nFilesCount; i++) {
            var Result = Interop.Call("shell32", "DragQueryFileW", wParam, i, lpszFile, lpszFile.Size);
            if(lpszFile.ReadString(0) != null) {
               Debug.Trace("File "+i+": "+lpszFile.ReadString(0));
               arrFiles.push(lpszFile.ReadString(0));
            }
         }
         break;
   }
}

thanks
