Petros,
1. Create a custom class that has a method that runs your process. It also needs a property to serve as a status flag.
2. Create a timer that checks a property and based on the value runs your process method.
3. Create a method for the custom class that instantiates an instance of the timer object and enables it. It then immediately issues a return.
4. Create an EXE and include both classes. Mark the custom class as OLEPUBLIC.

In your application, create an instance of the custom object and call the method that instantiates the timer object. Control will be returned to your calling application. The timer will fire and do the work to perform the process you. In you application, set up a mechanism to check the status flag property.

HTH.
