سلام


این کد اتصال usb و کلا device هست و نیازمند فعال سازی پلاگین MemoryEx هست .


در Global Function :

WM_MOVING = 0x0216;
WM_DEVICECHANGE = 0x0219;
DBT_DEVICEARRIVAL = 0x8000;
DBT_DEVTYP_VOLUME = 0x00000002;






function EventHandler(hWnd, uMsg, wParam, lParam)
    if (hWnd == mainWinHdl and uMsg == WM_DEVICECHANGE) then
    --MainWindows_DEVICECHANGE  
        if (wParam == DBT_DEVICEARRIVAL) then
        -- etesal device
        DEV_BROADCAST_HDRStructure = MemoryEx.DefineStruct(
        {UINT("dbch_size");
        UINT("dbch_devicetype");
        UINT("dbch_reserved");
        }
        );
        
        hdlDEVStruct = MemoryEx.AssignStruct(lParam, DEV_BROADCAST_HDRStructure);
            if (hdlDEVStruct.dbch_devicetype == DBT_DEVTYP_VOLUME) then
            -- etesal usb
            Dialog.Message("Notice", "usb device connected", MB_OK, MB_ICONINFORMATION, MB_DEFBUTTON1);
            end
        
        end   
    
    end
    
return Subclass.OldWinProc(hWnd, uMsg, wParam, lParam);
end

در OnShow :

mainWinHdl = Application.GetWndHandle();
Subclass.Create(mainWinHdl, EventHandler);

در OnShutDown :

Subclass.Remove(mainWinHdl);
