There can be only one incidence of a particular Member ID in the people table but that person may register for several different events. There are two other types of controls available to Visual Basic beyond the intrinsic ones. ActiveX controls are designed for more complex operations than the intrinsic controls we have used to this point. They work the same way as the intrinsic ones but are not a part of the Visual Basic control package. ActiveX controls employ a standard technology called component object modules and these can be used with a variety of programming languages.
Insertable objects comprise another type of control.
We are going to use several ActiveX controls in our project. These will include the DBCombo box control, the DBGrid control and the Windows Common Dialog Box control. The DBCombo box control is a combo box that will tie directly to a field in a database. The properties for this control can be set using the properties window or through code. Remember that you must have a configured data control on your form before you set the properties for the DBCombo box.
