Description

The NetControlBox component is used to load .NET components registered in global assembly cache (GAC) and to work with them.

Working with the Component

The global cache stores the assemblies installed for joint use by several applications on a computer. The registered components are loaded during the form work by the corresponding methods of the AttachControl or CreateControl component. The access to the loaded component is granted by the Control property. Further work with the component is executed by the resources of the ForeNet assembly.

NOTE. For details about global assembly cache (GAC) see additional documentation: Windows help, MSDN.

Proper components developed in the Fore.NET language can also be loaded to the component. These components must be inherited from the System.Windows.Forms.UserControl class. If required, code of any Fore.NET form can be moved to the code of proper component (it will be necessary to move code of the form designer and events handlers).
