This problem is connected with OLEDB but not with DbxMda. Please try to clean the registry on your machine (using, for example, the Ccleaner application).

I also get this problem using a mysql 5.x database from a delphi 7 application. The error is triggered for me when a connection is closed during the destroy procedure of the sqlconnection object. the error is in the TSQLConnection.RegisterTraceCallback(Value: Boolean); call
Code: Select all
if Assigned(FISQLConnection) then
begin
Check(FISQLConnection.SetOption(
TSQLConnectionOption(eConnCallback), Integer(0))); <-- dies here in sqlexpr.pas
