I need to be able to grab the mouse move events while the user is moving over a CRichEditCtrl, and determine the character position of the mouse. &nbsp;In other words, the OnMouseMove() method tells me a CPoint, where the mouse pointer is, and I need to convert this over to a<br />
character position within the control. &nbsp;<br />
<br />
Anyone any ideas<br />
<br />
Cheer <br />
