They are all the same format (columns, rows and data), but on one file there is an error. The data in one column is: row 1: 83,07 row 2: 11,57 row 3: 6,22 row 4: 0 but delphi sees it as date: row 1: row 2: 30.12.1899 11:57:00 row 3: 30.12.1899 6:22:00 row 4: 30.12.1899 Why am I getting it as date? Is there any way to force it to see it as number? Back to top Vassiliev V. V.

Rgds, JohnH Back to top Luka Guest Posted: Tue May 15, 2007 8:11 am    Post subject: Re: TXT delimited (;) filles problem I found the answer to my problem, adding IMEX=1 to the connection string tells the query to interprete all the data as text. And then I convert string to number with strtofloat(); The connection string then looks like this: adoquery1.ConnectionString:='Provider=Microsoft.Jet.OLEDB.4.0;Data Source=g:\temp+';Extended Properties=''text;FMT=Delimited; IMEX=1'''; To answer Del, all the files have numbers with comma; To answer Chris, schema.ini file is needed if the text file is TAB delimited, and when delimiter is comma, or some other symbol (like it is not needed. Thanx everyone for replays, maybe this solution will help you all at some point Luka "John Herbster" <herb-sci1_AT_sbcglobal.net> wrote in message news:4648e7f9 (AT) newsgroups (DOT) borland.com...

Thanks for the IMEX information - I am glad you have solved the problem. IFAICT this does not seem to be documented by MS with respect to text import (however, http://support.microsoft.com/kb/194124/EN-US/ describes IMEX for import from Excel). BTW, in my experience, the effect of changing the delimiter in a file that successfully imports without a schema.ini from comma to semicolon was to require a schema.ini specifying for that file format=delimiter(;) YMMV.
