I have some problems with the drawing in the MoveTo function (and in the refresh). I manage to draw the new line when the mouse is moved but I don't know the proper way to remove the old line. Thus the screen is filled with all the old lines until I do a refresh. </SPAN><BR /><BR /><SPAN>I know that I can do this global refresh but I would like to do it the right way. In the IDisplayFeedback, I have access to the IScreenDisplay interface. Do I have to use the invalidate method? Does someone have an example of clean code for the MoveTo and Refresh functions?</SPAN><BR /><BR /><SPAN>I will greatly appreciate any help/comments</SPAN><BR /><SPAN>Thanks a lot</SPAN></BODY></HTML> Fri, 06 May 2011 09:14:57 GMT ThibautDusanter 2011-05-06T09:14:57Z IDisplayFeedback Refresh https://community.esri.com/t5/arcobjects-sdk-questions/idisplayfeedback-refresh/m-p/590132#M15932 <HTML><HEAD></HEAD><BODY><SPAN>Hi,</SPAN><BR /><BR /><SPAN>I am developing a custom display feedback.
