I want to import some data from an Excel file ( xls ) by using TADOConnection and TADOTable.

I connect to file with no problem, but when i open TADOTable some fields have ftFloat datatype because their values in excel file are numeric, but their values are not a number!

I want all fields of TADOTable (columns of Excel file) to have ftString datatype.

I set the types of columms in Excel file to Text but no changes affected!

How can I do this?


Question: What happens to light and mass in the center of a black hole?
Answer: Simply put: we don't know. From our perspective a black hole cuts off its interior from the rest of the Universe, the only aspects of a black hole that remain are mass, charge, and spin. In truth, even barely understanding what happens inside the event horizon will depend on an understanding of quantum gravity, something which we do not yet have. And even then it will still be largely theoretical since we have no way of interacting with the interior of a black hole.
