Fast answer needed!

Hi everyone...

I need a fast answer to the following problem:

I want to connect to a Paradox database using the TADOQuery component. I have to provide a connection string, but I can't figure out what I have to put in there. The only specification is, that I can not use a predefined DSN, since I must be able to specify the driver (and all other data) manually.

Any help?

Jonny..

The best connection to Paradox tables is to use BDE, TTable, TQuery...

I didn't think that ADO can wotk with Paradox, because ADO is a Microsoft's and Microsoft didn't know Paradox.

Hi Motaz...

Sorry, you're wrong about that. If I provide a DSN, it works just fine. But I want to prevent providing a DSN, since all our products using BDE and we only start to use ADO. This would mean, that we have to install a additional DSN on all client machines, which I want to prevent. Another solution I can accept, if someone knows how to create a DSN from Delphi.

Regards, Jonny...

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

jonnyfive.... just like a suggestion, why don´t you install the DSN from Delphi when the application doesn´t find it ?

I did that in the past with a DSN of a ODBC driver for Sybase.

You can Use RegEdit from Delphi to write the apropiates instances and keys params (like the driver path) and it´s just works equally as if you installed the DSN...

If you want to know more about it... let me know and I can provide the code I used.

The simplest answer ain't so simple...but here goes.

Create a FileDSN that points to your database, now you can ship the *.dsn file you just created with your software and access it like so...

Provider=MSDASQL.1;Persist Security Info=False;Extended Properties="CollatingSequence=ASCII;DBQ=H:\PROGRAM FILES\COMMON FILES\BORLAND SHARED\DATA;DefaultDir=H:\PROGRAM FILES\COMMON FILES\BORLAND SHARED\DATA;Driver={Microsoft Paradox Driver (*.db )};DriverId=538;FIL=Paradox 5.X;FILEDSN=H:\Program Files\Common Files\ODBC\Data Sources\Paradox.dsn;"

or

you can open it (the *.dsn file) with a text editor and delete the

[ODBC]

from the top line, then concatenate all the lines together seperated by semi-colons and insert them into a connection string like this...

Provider=MSDASQL.1;Persist Security Info=False;Extended Properties="CollatingSequence=ASCII;DBQ=H:\PROGRAM FILES\COMMON FILES\BORLAND SHARED\DATA;DefaultDir=H:\PROGRAM FILES\COMMON FILES\BORLAND SHARED\DATA;Driver={Microsoft Paradox Driver (*.db )};DriverId=538;FIL=Paradox 5.X;MaxBufferSize=2048;MaxScanRows=8;PageTimeout=5;ParadoxNetPath=H:\WINNT\System32;ParadoxNetStyle=3.x;ParadoxUserName=admin;SafeTransactions=0;Threads=3;UID=admin;UserCommitSync=Yes;"

hope this gives you an idea

l8knight, As you say you are new:

The philosophy here at e.e. is always post answers or suggestions as a comment because that will not block the question to other experts that maybe will have a better answer (like you). And then the people who ask will have several alternatives to resolve his problem and decide was the best alternative to him. (he can Accept a comment like if was a Answer).

So welcome!!!!
