Your function probably differs from its prototype
(second and third parameters conflict),
or needs to be prototyped.
Send full program code for exact answer.

You should use the exact WNDPROC declaration for defining your function:

  LRESULT MyWndProc(HWND hwnd, MSG msg, WPARAM wparam, LPARAM lparam)
  {
    // rest of your code here.
  }
