title: WebView2 based ActiveX control and intercepting WM_LBUTTONDBLCLK
body: <p>I've got a legacy VS2008 application that requires WebView2 integration, the older IE implementation is no longer viable.  To accomplish this I've created and ActiveX control that wraps up the WebView2 API in VS2019.  The parent VS2008 CDialog supports multiple instances of this ActiveX control in a grid via CreateControl(). InvokeHelper() is used for simple URL and visibility commands.</p>
  <p>All works and functions as expected.  However, I need to intercept a double mouse click message to toggle full screen for the ActiveX control over which it was performed.</p>
  <p>Problem being I just don't seem to be able to intercept this message.  The ActiveX control appears to intercept the WM_LBUTTONDBLCLK message first and simply dismiss it.</p>
  <p>Any advice on how to intercept this message would be more than greatly appreciated.</p>
