Let user create snapshot (QVD) by pressing Button?
Hi all, what I need to achieve is that users can create their own snapshots of current data by pressing a button in the front end. And, then be able to switch between the current data (combined from SQL dB + flat XLS files) and historical data (QVD's created over time) as they see fit. The switching then to be done by 'simply' selecting from a Listbox that shows available datasets. Next step, would be / but let me get this right first, is comparing between current data and one/more snapshots... Thanks for your input, regards, Zach.
