[Code explanation] On the button click procedure write the code to create an object of Text Box class, and set the properties like name, Size and location, and then we add this control to Group Box control with the help of Controls.Add() function.[Create Dynamic Label][Add event at run time]From the above we create controls at run time and now we move to next step- create event handler at run time and attach that event to the control. Now you can ask questions directly to me on my new site ASPForums.
A code group contains a permission set (one or more permissions).
Code that performs a privileged action will perform a code access demand which will cause the CLR to walk up the call stack and examine the permission set granted to the assembly of each method in the call stack.
You would have to first handle the Preview Key Down on the textbox so when ENTER came along you would set Is Input Key so that it could be handled by or forwarded to the key Down event on the textbox.
I had the same problem and I could not make this answer work on Framework 2.0 so I dug deeper.
NET framework, is Microsoft's solution to prevent untrusted code from performing privileged actions.
When the CLR loads an assembly it will obtain evidence for the assembly and use this to identify the code group that the assembly belongs to.
Process Cmd Key(msg, key Data) End Function Private Sub tb Security_Key Press(sender As System.
Key Char) End If End Sub Private Sub txt Password_Preview Key Down(By Val sender As System. Like this: Private Sub txt Filtro_Preview Key Down(By Val sender As System.
This prevents downloaded code from performing privileged actions.
