ElseIf e.KeyValue <> Keys.A Then
CheckPin1.CheckState = CheckState.Unchecked

I have a question regarding the checkbox. Here is the scenario: I have three groupboxes which I have initially set as invisible. I have three checkboxes out to the side. If I check a checkbox, is it possible to have one of the groupboxes become visible just by checking the checkbox and nothing else. (I mean without clicking a button or anything, just clicking the checkbox and then having a groupbox become visible).

im trying to detect if the connection is still active upon trying to send or receive anything. Now I have checks in place if it's connected then it will send or receive however... it's saying it's connected when it is not connected... and therefore my program tries to send and receive and errors.
I am determining if it is ok to send and receive by using the Socket.Poll(-1, SelectMode.SelectWrite)
if it's true then im connected and data can be passed..This seems to always be true until I send something and it fails..How can I catch the socket not being connected before it fails upon sending or receiving?
I work as an IT Administrator and manage a few Servers, Routers, VPN Connections over a number if locations. What I am wanting to do is create a vb.net app that will go out and ping say every 2-5mins each of the servers, routers, that are listed and then shows beside the Hostname a Green Circle which means online and if its a Red Circle its offline, and the screen refreshes if their is a problem or a device / service comes back online.
Then if its offline email a particular email address showing the hostname of either the server or router and which location saying its offline. If possible to make it easier to change the devices to show possible have a txt file or something like that with the Hostname, IP Address, Location.
