   CPoint point 



Indicates whether various virtual keys are down. This parameter can be any combination of the following values:

  • MK_CONTROL   Set if CTRL key is down.

  • MK_LBUTTON   Set if left mouse button is down.

  • MK_MBUTTON   Set if middle mouse button is down.

  • MK_RBUTTON   Set if right mouse button is down.

  • MK_SHIFT   Set if SHIFT key is down.


Specifies the x and y coordinates of the cursor. These coordinates are always relative to the upper-left corner of the window.

This member function is called by the framework to allow your application to handle a Windows message. The parameters passed to your function reflect the parameters received by the framework when the message was received. If you call the base-class implementation of this function, that implementation will use the parameters originally passed with the message and not the parameters you supply to the function.
