Hi, I am using following piece of code to remove all annotations from the selected page. Though it deletes all annotations from selected page, but sticky note annotations are still present on the page. Any help on this please.. QP.SelectPage(1); int nAnnotCount = QP.AnnotationCount(); for(int nIndex=1; nIndex<=nAnnotCount; nIndex++) { int nRetVal = QP.DeleteAnnotation(nIndex); } Lakkan

It does not completely explain the symptoms you describe, but the direction of your loop is incorrect. For deletions, you should normally start with the last item and decrement the index. Otherwise the deletion of item 1 will change the index in all the later items, and the deletion will fail when the index exceeds the number of items remaining.
