Hi,<BR><BR>I'm developing a VB program which reads excel files from a shared folder and inserts data into database. This VB program runs by the schedular 3-4 times a day. The first cell in each excel sheet indicates the date the data belongs to. Since these files are being referenced by other tools I can not move/delete the files from the shared folder after database update. <BR><BR>Here is the issue. We don't want the VB progam read the same data again and again. It should read the data and update the database only if the data is for new date. I'm not getting any good ideas to handle this issue. I *really* appreciate any suggestions.
