I started looking at it today, but do not see anywhere that allows someone to specify "who" is controlling the services. Where does the service controller d ...Show All

• Architecture Advantages of OOP ?

  Hello, Im a fun of OOP designs. I design my bussiness classes when I start a new project.

So my conclusions are: Only plain Button objects may be assigned to the Form ...Show All
