Virtual Arduino without Arduino

I need to programming Arduino and Ethernet Shield but I have not both!

How to do that?

I have tried to do it with Virtual Bread Board (VBB), but there are no Ethernet Shield.

I need to use server and client in my project. Client will be on Arduino+EthernetShield, but server will on PC and it will be written on C.

If you don't have the hardware, what good will the software do you?

And anyway, wouldn't you also need virtual LEDs, virtual motors, steppers, thermistors, LDRs, transistors, FETs, switches, VFDs, ethernet hardware, accelerometers, etc? And a virtual emulation of the physical world in which the sensors live, to provide varying input, and a virtual person to observe the led blinking?

... And then we'd all be living in The Matrix, and look where that leads.

ok… I can run LED Blink on VBB… but I need more! I got code from here Arduino Tutorials - Ethernet+SD

there are link on sorce:

It is WEB server … and I need to test its! On VBB!

Is it impossible?

I have many errors in code… I think that VBB think that code is Java, but it is C!

It does not. It knows it is C++. However, it does not know about all the libraries you are trying to reference.
