The Control Manager enables you to install and uninstall custom ActiveX controls on a device or emulator. Additionally, the Control Manager provides an easy interface for copying and registering controls for your project. You also can use the Control Manager to confirm that the ActiveX controls you use in your application exist on your target device before you run the application.
When you install the toolkit, it automatically registers all supported ActiveX controls to your desktop computer and emulation device. When you create an application, you must register any controls used in your application on the device. Additionally, you must register any custom ActiveX controls used in your application to your device, emulator, and desktop computer. If a control is already installed and registered, the Control Manager displays “Yes” next to the control name in the Control Manager window.
Note All ActiveX controls must be registered before your application can use them. Attempting to use a control that has not been registered generates a run-time error.
