hi Yuri,

I have tried that but it doesn't help for me :(

The code I used to copy the DBF is shown:

close tables
TempName="C:\TEMP\MySource.DBF"
copy file "&TargetPMS" to "&TempName"
use &TempName
thisform.myGrid.recordsource=&TempName

still become blank after this code, and not a normal blank, even the grid lines of the grid are disappeared..
