WINAPI Capturing right mouse click

i have a problem with capturing mouse clicks. I have to cases:

-WM_NCHITTEST that Drag and Drop window (capture click&hold)

and

-WM_RBUTTONDOWN which is a rightclick conext menu

I have no idea how to combine those two so that they both could work properly. For now, only NCHITEST works - it takes all the clicks. RBUTTONDOWN is never entered. Any help with that?

case WM_NCHITTEST:  
        {  //Function used from MSDN
            POINT p = { LOWORD(lParam), HIWORD(lParam) };  
            ::ScreenToClient(hWnd, &p);  

            RECT r;  
            GetClientRect(hWnd, &r);  

                return PtInRect(&r, p) ? HTCAPTION : DefWindowProc(hWnd, message, wParam, lParam);  
            }
break;

case WM_RBUTTONDOWN:
    KillTimer(ball, ID_TIMER);
    p.x = LOWORD(lParam);
    p.y = HIWORD(lParam);
    hPopupMenu = CreatePopupMenu();
    ClientToScreen(hWnd, &p);

    AppendMenuW(hPopupMenu, MF_STRING, IDM_EXIT, L"EXIT");
    InsertMenu(hPopupMenu, 0, MF_BYPOSITION | MF_STRING, IDM_EXIT, TEXT("Color Picker"));
    SetForegroundWindow(hWnd);
    TrackPopupMenu(hPopupMenu, TPM_RIGHTBUTTON | TPM_BOTTOMALIGN | TPM_LEFTALIGN, p.x, p.y, 0, hWnd, NULL);
    DestroyMenu(hPopupMenu);
    SetTimer(ball, ID_TIMER, 1, NULL);
    break;

Maybe you can handle WM_NCRBUTTONDOWN:

case WM_NCRBUTTONDOWN: {
    if(wParam==HTCAPTION) {
        TrackPopupMenu(hMenu,TPM_LEFTALIGN|TPM_RIGHTBUTTON,GET_X_LPARAM(lParam),GET_Y_LPARAM(lParam),0,hWnd,NULL);
    }
    break;
}
