Whenever I click the "ShowReport" Button placed on VB form, The report appeared is not refreshed. How can I do this in VB that whenever I want to see the report, it will be refreshed and contained the whole data of the table.I have clicked the "Refesh data on every print" on the Repoting Tab of the sub menu "Option...." .

Make sure that the SAVE DATA WITH REPORT option is not checked, under the file menu.
