Hi,

I am looking for a wait function which will wait and stop the thread where it's running till specific system time (or when signaled).
for example, if the target time was set to 12:30, i'd like the program to run and the function to wait till 12:30, and then to wake up.

I've already found the WaitForSingleObject function but in this function you need to specifiy the waitting time in miliseconds...
in that case i have to calculate the time in milisec from now till the target time. this is my default choise for the moment..

Thanks!

Solution 2

WaitForSingleObject is a good choice. What's the problem with milliseconds?

How about AutoResetEvent.WaitOne(TimeSpan) ? You can create a TimeSpan object using the "-" operator on two DateTime objects. Thus, you can use something like:

AutoResetEvent^ m_event;
[...].
DateTime ^present = DateTime.Now; 
DateTime ^future = gcnew DateTime...
m_event->WaitOne(future - present);

Sorry this is only valid for C++/CLI
