AFAIK (my debugger confirms) it has and you don't need to derive from it to have a vtable.

You should use corresponding socket API's, instead of following this approach.
However, you can refer Console functions[^], and see what fits your needs.

Thanks for your reply. But actually I used the netsend command for example purpose only. I want to use some commands like cd directory, cd.., and run some .exe from console.
Can you help me in that ?
Thanks for your prompt reply.

There is equivalent of very command you like to run from command prompt. You can use CreateDirectory in this case.

You can use ShellExecure, CreateProcess for this purpose. Refer its documentation.

The error you mentioned is obvioulsy runtime error, not compliation error. Try to debug the code, giving you this problem.
Post some relevent code , to asses the problem.
