title: Send an event from the c# winform parent window to the c++ mfc window
body: <p>Transfer the handle of the C# winform parent window to c++ dll via the dllimport function. After that, I would like to call Create Window with the handle as my parent and send the event that occurred in the winform parent window to the generated window. (resize, move, etc.)</p>
  <p>(Can I catch an event in onMove, onSize in the mfc window without using postMessage in the winform window?)</p>
