how do i make a program wait indefinitely

[Vivek Vijayan]

i m doing an networked application.how do i make a program wait indefinitely until an input is received...like getche() or getch() in c

This code was posted by me...

The best way is to wait on AutoResetEvent or ManualResetEvent and once the input is constructed, to signal those events

cant we do without using thread???

It seems to me that your desired result is to be interrupted once the input is received. Interruption by definition means context-switching (threads). You can apply a different approach (which is not a good design), by checking a boolean variable in a while loop. As stated this isn't desired as: 1. You will waste the cpu cycles 2. You will have threads anyway 3. You will need to deal with the race condition by applying locks - as one thread will read the boolean whereas another thread will write.

I always thought it was cin << ReadKey(); ...Or has my memory gone KABOOM! again?

That's C++. :-D

Are you sure you don't want a Windows Service?

You don't need a lock for a bool though, just make it volatile and be careful when reading it (copy to local first)

Input from what, the network? If so, just do a blocking read without timeout?

[Vivek Vijayan]

yes from network how do i block read??

If you make a NetworkStream, a normal Read should be blocking - I think. But don't trust me on this one, go to MSDN and check..
