Hello,

I've try to add a menu whith the code below in myPostInitControl :

{
   CFrameWnd *MachFrame = MachView->MachFrame;           //Prblem here -> MachFrame = 0x00000
   CMenu *menu = MachFrame->GetMenu();
   HMENU hSubmenu = CreatePopupMenu();
   int pos = FindMenuItem3(menu,"PlugIn Control");
    //here we can add menu items to MAch3's menu..
   int x = pos;
   HMENU control = GetSubMenu( menu->m_hMenu, pos);
    InsertMenu ( control, -1, MF_BYPOSITION, RangeStart , _T("kk") );
   MachFrame->DrawMenuBar();*/
}

Compling is OK but when I start mach3, I've gort a error triged . After debugging the dll, I saw that MachFrame  is equal to 0x00000 so there is a probleme somewhere.... Do you know where is the problem whith this code ?

I've use the "mach3 internal and plugin bible" http://www.google.fr/url?sa=t&source=web&cd=1&ved=0CB0QFjAA&url=http%3A%2F%2Fwww.cnczone.com%2Fforums%2Fattachment.php%3Fattachmentid%3D113858%26d%3D1283534276&rct=j&q=mach3%20plugin%20bible&ei=iafJTZ6aK8TMhAe1h-isDQ&usg=AFQjCNEpq4AGpFKRAqSJRPQAkVSXY1PcwQ&sig2=fiIfMq0sLSH2yqb4P_68Vg&cad=rja

Thanks a lot for your help.


PS : I can add a menu by searching the "Mach3 CNC" window and using his HWND, that works perfectly... but myNotify is not called when I click a menu item under mach3... :( So I dont know hox to do for handle Menu Item click in thsi case ...

Yes ! I got it running :)

This is what I've done :
On MyInitControl I initialise RangeStar :

void myInitControl()
{
   RangeStart  = GetMenuRange( 1 );
}


On MyPostInit I call a thread that will search for MAch3 windows while mach3 is loading. When mach3 is found, it add the menu item :


void myPostInitControl()
{
   AfxBeginThread(ProcessFindMach3, NULL);
}

The code for my thred is :

UINT  ProcessFindMach3(LPVOID param)
{
   do {
      EnumWindows(EnumWindowsProc2, NULL);
   }while(mach3Wnd==NULL);

   mach3CWnd.Attach(mach3Wnd);
   dlg = new CProbeDlg;
   dlg->Create(IDD_DIALOG_CONFIG,&mach3CWnd);

   
   static bool menued = false;
    if( !menued)
    {
        //" Startup of Menu handler"
        menued = true;
      if (mach3Wnd != NULL)
      {

         CMenu *menu = mach3CWnd.GetMenu();
         HMENU hSubmenu = CreatePopupMenu();
         int pos = FindMenuItem3(menu,"PlugIn Control");
         //here we can add menu items to MAch3's menu..
         int x = pos;
         HMENU control = GetSubMenu( menu->m_hMenu, pos);
         InsertMenu ( control, -1, MF_BYPOSITION, RangeStart , _T("Probe") );
         mach3CWnd.DrawMenuBar();
      }
   }
   return 1;
}

My Callback routine :

BOOL CALLBACK EnumWindowsProc2(HWND hWnd, LPARAM lParam)
{
   char String[255];

   if (!hWnd)
      return TRUE;      // Not a window
   if (!::IsWindowVisible(hWnd))
      return TRUE;      // Not visible
   if (!SendMessage(hWnd, WM_GETTEXT, sizeof(String), (LPARAM)String))
      return TRUE;      // No window title

   GetWindowText(hWnd,String,0);
   CString toto(String);
   if (toto.Find("Mach3 CNC",0) !=-1)
   {
      mach3Wnd=hWnd;
      return 1;
   }
   
   return TRUE;
}

And FinWindow :

int FindMenuItem3(CMenu* Menu, LPCTSTR MenuString)
{
   ASSERT(Menu);
   ASSERT(::IsMenu(Menu->GetSafeHmenu()));

   int count = Menu->GetMenuItemCount();
   for (int i = 0; i < count; i++)
   {
      CString str;
      if (Menu->GetMenuString(i, str, MF_BYPOSITION) &&
         (strcmp(str, MenuString) == 0))
         return i;
   }

   return -1;
}


I have also Add the notify routine ion my .cpp:

extern void myNotify(int ID);

extern "C" __declspec(dllexport) void Notify(int ID)

{
   AFX_MANAGE_STATE(AfxGetStaticModuleState());
   myNotify(ID);

   //Called when reset is pressed, at end of actual reset commend in Mach3.
   //Check the Engine.Estop variable to see if we have reset or not..
}

And in MyNotify I got the message ID when I click on menu item, so I call My Plugin :

void myNotify(int ID)
{
if (ID == RangeStar)
{
....
}
}

Sorry, it is not correct because we cannot create a Dlg in a thread... So I must create the dlg outside the thread...

THere is no notify when mach3 is completly loaded ??

Ok, I do this and it works :

UINT ProcessFindMach3(LPVOID param)
{
   do {
      EnumWindows(EnumWindowsProc2, NULL);
   }while(mach3Wnd==NULL);
   MachWindowFound = true;
   return 0;
}

And I create the Dlg in MyUpdate :

void myUpdate()

{
   // DbgMsg(("myUpdate entry"));

   if (MachWindowFound == true)
   {
      MachWindowFound = false;
      CreateDlgOutside();
   }



   // DbgMsg(("myUpdate exit"));
}

void CreateDlgOutside(void)
{
   mach3CWnd.Attach(mach3Wnd);
   dlg = new CProbeDlg;
   dlg->Create(IDD_DIALOG_CONFIG,&mach3CWnd);
   static bool menued = false;
    if( !menued)
    {
        //" Startup of Menu handler"
        menued = true;
      if (mach3Wnd != NULL)
      {

         CMenu *menu = mach3CWnd.GetMenu();
         HMENU hSubmenu = CreatePopupMenu();
         int pos = FindMenuItem3(menu,"PlugIn Control");
         //here we can add menu items to MAch3's menu..
         int x = pos;
         HMENU control = GetSubMenu( menu->m_hMenu, pos);
         InsertMenu ( control, -1, MF_BYPOSITION, RangeStart , _T("Probe") );
         mach3CWnd.DrawMenuBar();
      }
   }
}
