A problem about connecting ASA by ADO component of Delphi?
Is there anyone to try to use ADO component of Delphi to connect ASA?
I fail to do it.
I manipulate database by TDataSource,TADOQuery,TConnection components of
Delphi, and set up connection with ASA guide. When running the program, the
connection is set up successfully. But a EoleException is thrown once I
make a query using TADOQuery. System prompt "unknown error". Who knows what
happened? Is it a compatible problem between ASA driver(ASAProv) and ADO
component of Delphi? (All are ok when connecting ASA by BDE components).
Is there anyone to try this??

I am working on a product that has been 2 years in development. It is
currently in production, but we recently added a new feature that
required a new database connection to the main office database from
satellite locations. Many of these locations use different internet
providers to connect to our private network, and sometimes these
connections are not very reliable. On top of that, our database server
is now being hammered.
We're experiencing 'parameter @someParam not found', and 'query timeout'
errors. The first error happens more on low end machine...ADO Connection problems
I am using C++ Builder 5 with ADO and SQL Anywhere 7.0.499 and Win 2K.
I put a TADOCOnnection on my form and go to the ConnectionString
property and hit Build connection. I select the Adaptive Server

connection. The connection is succesful. Then I go to my
TADOConnection and hit connected = true, and I get an error of "Invalid
Enum Value". Then I switch everything over to the ADO for ODBC
Connections and hook up everything and test the connection and it
returns successful. Then I go to set the Connected p...ADO.net problem: i can not view image data for the rest of my table rows except the image for the first row but i can read all the other non image fields for all rows.

What were you using as connection before you migrated? Why
did you choose ADO.net?

I have to connect to a db using adodb (which i select from the references). I have to retrieve the car models from the database and bind them to a listbox. I am not sure how to proceed and I can't find any articles on ADO with .net and data binding.
Here is the code that i tried but it only retrieves the car model for the specified id. If I delete the id it doesn't work. Also it writes the car model in the listbox vertically such as:

I'm having trouble getting the ADO objects to connect to our Sybase 11
server. I believe I'm using the latest Sybase ODBC client, but the
connection fails every time (on the Connection Open method).
I guess the problem lies in the configuration of the client-- can anyone
provide me with the steps to set this up properly? I've installed the
latest MDAC setup from Microsoft (1.5 something) and the latest Sybase ODBC
drivers, set up my System DSN, etc. (which I've verified works), but still

As my saga continues from my previous post, I was finally
able to establish a connection to a SQL Server Compact

I successfully created a database profile using ADO.Net and
was able to create tables and pipeline data in. But when I
try to connect to the database during runtime using the same

The syntax in the Preview tab of the database profile looks
