Reasons for ...ADO Connection Errors
I have a multi-threaded application that hits both a local
database and a central one (over a low bandwidth connection). The same
code executes against both, depending whether the client being processed
is a local or central client. I open database connections, perform my
operations, and close them.
I am getting connection related errors such as:
a) 'Cannot create a new connection because in manual or distributed
transaction mode' when trying to establish a connection.
b) 'Operation cannot be performed while executing Asynchronously'. This

I have a script (attached) that creates an Access 2K database,
connects to it, creates a table, and pops some data into it. It all
works, no problem. However, I'm getting the following messages
on the console (CMD prompt):

I tried to connect to ASA7 via the new OLE DB - Provider and ADOExpress from
Delphi 5.01. No chance. Only the error message 'Invalid Enum Value'. About
the new provider I haven't heard anything good until now...

All right here's my problem:
I have several aspx pages that work together using a Access database. They work fine for awhile and then all of the sudden it hits an error opening the database. I should mention that this problem does not occur when I'm just using the web matrix server instead of IIS. It doesn't make any sense to me. I was hoping someone else could help, Any takers?
O.K. I was wrong it does occur with the matrix server. It just takes longer to happen. Heres a thought? Does Access have a max number of connection?

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:

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??
