>>>I have a problem with Crystal Reports and ADO RecordSets, the first recordset I submit to a report is correctly shown when printed or previewed. But if I do some changes and submits the new recordset, the report is not updated with the new data, instead it shows the old data.
>>>
>>>What I found out in the Preview control is a Refresh button, if I press this button I get the latest recordset. But how do I do a refresh in code?
