Basically I want to have a picturebox which shows an embedded resource if not connected to the internet, and an online image if connected to the internet.I assume this can be done on the form load event, I just don't know the code for it. Basically this is the logic though:
-If 'http:/[url].... is available (therefore connected to internet)
-Picturebox1.Image = http:[url].....
-Else[code].....
How can I code that properly? Would putting it in the form load event work?

Well, I have a form called customers. Login form and mainform.
So my clients want to have an option that explains this: If a user enters information in the customer form, then that information has to be confirmed by admins panel.
Get me well. When application program loads with a limited user, I set some buttons hidden so that only admin can see it when they log in. so in that case, users are not capable of inserting anything in the customer form.
But this time they want users to insert information then the information goes to administrators to confirm the information...if admins accepts the information, then information is then goes to customers table in database. If they don't confirm it, then that information will be ignored.
