Paradox Tables (Languages & Exporting)
I'd appreciate it if someone could let me know if there is a way of exporting Paradox table data into some sort of file (comma delimited or otherwise). And then importing that data into another table (with same fields, except a few extra fields appended after the original fields), thus preserving the data.
Also is there a preffered Table Language to set a table to so that users can save Internatonal character data? I'm using Paradox 'ascii' as my Table Language and a user is complaining that it does not save his Greek character data correctly.
Thanks in advance for your help.

I know of a easy way to export your table to an ascii file, as well as, import it back. I don't however have the slightest idea about the Greek part. If you want me to answer the question - without the greek portion - I will, assuming you will grade it if it works for you.

Yes of course I will give anyone the points they deserve should they help me with a problem. (Still require help with the Language problem I have with Paradox tables)
The code that ronit posted works great for converting from Paradox ASCII -> DOS Text ASCII
Now when I tried to change the code to convert from the (exported) DOS Text ASCII file to a Paradox ASCII file I received the following error:
Project Project1.exe raised exception class EDBEngineError with message 'Invalid parameter.' Process stopped.
This happens on the open method of t2 (where the program halts in the code)
I have created an empty database with the same fields required (because all I wanted to do was import the data from the Text ASCII file into the Paradox ASCII table)
Here's what my code looks like for the DOS ASCII -> Paradox ASCII conversion :
// Converts from ASCII text file to Paradox DB Table
procedure TForm1.Button2Click(Sender
var
t1, t2: tTable; {t1 = ASCII; t2 = Paradox}
begin
t1 := tTable.create(self);
with t1 do
begin
// Open TXT file from current directory
DataBaseName := '';
tableName := 'myfile.txt';
tableType := ttASCII;
open;
ShowMessage('Successful TXT file open');
end;
t2 := tTable.create(self);
with t2 do
begin
// Save to current directory
DataBaseName := '';
tableName := 'myfile.DB';
TableType := ttParadox;
createTable;
Open;
Edit;
BatchMove(t1, batCopy);
close;
ShowMessage('Successful IMPORT');
end;
t1.close;
end;
Thanks for all help.

If you want to copy to a paradox table and this table already exists then try to delete the command createTable;
I think you won't get then the error 'invalid parameter... '

About the greek stuff, I think you should do the following:
1. In Delphi3 activate the Bdeadmin.exe which is in
C:\Program Files\Borland\Common Files\BDE
2. In the configuration page enter the
Configuration\Drivers\Nati
3. Change the property LANGDRIVER from 'ascii' to
Paradox Greek GR437 and save.

Thanks Ronit - with a few changes it works like a charm now - the conversion and exporting from one table to another.
