>Also , i want to ask another question that, if i display the table on the grid, the column header is what the fields name, how can i change the display column name into a meaningful name?!

Wai Wai,

The gird has columns and the columns have Headers the header's caption property is what you see at the top of the column. By default VFOP uses the field name when you don't tell it what to use.

You can set the ColumnCount in the grid and then set the Caption of each header to what you want.
