Provider cannot be found. It may not be properly installed. Context ADO-MySQL-Delphi
I installed the ODBC driver for MySQL on W2K (Have Delphi 7 enterprise)
The ODBC shows everything right
When trying using ADO in Delphi, I get : Provider cannot be found. It may not be properly installed.
as soon as I try to connect.
The Provider properties does not show the "MySQLProv" but I force it in the connectionstring...

Apparantly you don't have an ADO provider for MySQL... Try connection by using an ODBC connection to MySQL instead.
Hi,
Install MyOLEDB driver for ADO instead of using ODBC.

A little bit better with MyOLEDB for ADO installed
Now when in the Delphi development I 'build' in the connectionstring, I get the list of provider and MysqlProv is there. I continue setting, click on 'test connection'.
There I get a MySQL data source name setup screen (look ODBC ???)
It look correct (says default in the name, but server and db and UID are okay)
I click ok and now I get this : "test connection failed because of an error in initializing provider. unspecified error"

Good suggestion, Alex.
I will try that DBExpress.
Hope I don't have too many things to install on that of W2K and Delphi 7 ...

Well, I had to find the 'right' libmysql.dll as the one provided with the Windows client for mysql was not working (5.x)
I succeeded to access a remote DB mysql on another machine, with a user without password.
But now when I put a password and adapt the connection parameter accordingly it fails (invalid username/password).
Trying however with a tool like mysql from a prompt it works, the connection is established.
Looking on the server (show status) I see the abort_connects increased by 1 each time I try activating the connection from Delphi.
I wonder if I shouldn't do something special to have that password correctly passed to the DB ?
