Hi,All,I am developing an ACTIVEX control embedded in IE, which is used to display continuous jpegs captured from a server.Firstly I wrote my ACTIVEX control in MFC,and call InvalidateControl() to realize control window redraw.It is ok.Then I rewrote my ACTIVEX in ATL,most of the code regards to grapic are same,but this time since InvalidateControl() can not be called in ATL based control, I call FireViewChange() to realize control window redraw time by time.However,I found that the control window got flicker when it is redraw.What happened and how to deal with? please contact: max_xiayi@hotmail.com
