I build an application using delphi 2007, and I am using ADO as database connection object.
in the application there is about 200 ADODataset\ADOQuery all those are connected to one ADOConnection and they exists in deferent Forms. The application can work with MSSQL server or Oracle.
The application works perfectly, but some times specially when I am using Oracle as backend, I am receiving an error "Object was open"
This error raise sometimes from deferent places. for example I open customer form, and I work on it, and it is perfect, but some times it raise the error "Object was open", If close the form and I open it again it works.

So the error happens specially when the application is connected to oracle database.
and it happens suddenly in deferent forms, and there is no way to follow certain steps to raise the error.
Please a solution

Note: I do not how to give a point on this questions
