I change the color of the line. Then I open a CDialog with DoModal().<BR /> The PROBLEM: The color of line is not changed! After closing the dialog the color is changed. <BR /> I think its a problem with actualize the autocad view.<BR /> This function does not work:<BR /> <BR /> CView* pActiveView = acedGetAcadFrame()-&gt;GetActiveFrame()-&gt;GetActiveView();<BR /> pActiveView-&gt;UpdateData(FALSE);<BR /> pActiveView-&gt;UpdateWindow();<BR /> <BR /> Could somebody help me? How can I update the view before opening the Dialog?<BR /> <BR /> Thanks for help!<BR /> Robert Tue, 10 Sep 2002 22:46:14 GMT https://forums.autodesk.com/t5/objectarx-forum/how-to-update-autocad-view/m-p/312315#M39392 Anonymous 2002-09-10T22:46:14Z https://forums.autodesk.com/t5/objectarx-forum/how-to-update-autocad-view/m-p/312316#M39393 May be the problem is in your code with changing entity's color.
