I have a grid containing a databaseA and have the following in the init method of a Form. I want to index on its field 'code'.

select databaseA
=cursorsetprop("buffering",3,"databaseA")
index on code to dbAindex

It runs fine in my Visual FoxPro. But when I built it to an exe file and run it. The following message appears
--- c:\xxx\dbAindex.idx is already exist, overwrite it?
If I clicked YES, a blank database will appear in that grid
If I clicked NO, the grid will show me the databaseA normally.

How can I solve this problem?
