Many friends have been properly displayed when using crystal reports, and when they are first loaded, they have been properly displayed. However, after conditions replacement, the report content is not updated in time. Although the refresh method has been used on crViewer actually VB Just simply use DiscardsaveData to release data in the Crystal Report Application before filling the record set, you can 'clear the data held in the report Objcrreport.Discardsaveddata' assignment to the report data Objcrreport.Database.SetDataSource Rstvsnet2003 There is no discardsaveddata. Method, I didn't have the data that didn't refresh when I used it. So I didn't test directly, but I can release the component when I should be overloaded on the interface. ObjreportDocument.dispose ()
