Vs.net C # calls an Active component

Active

The undeniable invocation of active in code can be very handy for programming, although Microsoft does not only call active components with. Net.
This example is an example of a simple Web page calling an active component that implements the data to be passed into and displayed in a control in an active component.
The instance code is as follows:
1. Establish an active component (created here with. NET C #)
(In this procedure: Set up Class Library add component class after put: Label, Button, GroupBox one)
It is important to note that you must add a reference using System.Security to the AssemblyInfo.cs of the class library before building the. dll, and properties [Assembly:allowpartiallytrustedcallers ()]. This is to give the control sufficient permissions to display it on the page.

2, the Web page calls the active component
Note Web page calls need to place active. dll in the Web's virtual directory.
