Re: time delay

Pick any value for your delay. I can guarantee that it will be wrong. This is exactly the
WRONG way to wait for an application to enter its message loop. Look at

WaitForInputIdle

which is the correct way to wait for a child process to come up. Note that like all wait
operations, this blocks the waiting thread, so if the thread is a main GUI thread, you
should not do a wait there; instead, you should spawn another thread which does the
WaitForInputIdle and posts a message back to the main GUI thread when the created process
is ready to accept input.

Generally, if you are in a situation where polling is required, you should always rethink
the problem to see if polling can be avoided.

For some details on how to use a separate thread to handle blocking requests and provide
asynchronous notification, see my essay on asynchronous process notification on my MVP
Tips site.
