Stop program execution for a specified time

gdont

How can I suspend a program's execution for a specified time? In particular, I want to make an event's code start running a specified time after the event fires. I think that it could help me solve the problem of firing the FileSystemWatcher.Created event which fires when a new file is being put into a "watched" folder. The problem arises when the file is big. Then the event fires before the creation of the new file is completed and the manipulation in the event handler procedure fails to execute. That is why I thought I could put an instuction in the event handler to "wait for" (i.e. an hour) but I do not remember how to do it. (any other idea to the problem will be welcomed) Thank you

Thank you very much. Could you give me a snippet of that code?

One way is is to block the thread until there are no file handles on the file you want to access, so you could check at regular intervals (0.5 seconds, maybe) to see if the file is still being accessed.

Unfortunately FileSystemWatcher class does not provide such an event. So I will have to estimate the maximum creation time and call Thread.Sleep(thatTime) (Do you know such an event? How could I get this information?)

You can prevent a certain code from being executed using threads. The thread that is supposed to hold the code can be delayed with the Thread.Sleep(int miliseconds) or Thread.Join(int miliseconds) methods. But that would work only if you know exactly the amount of time. In your case, you should use another event that will be fired when the creation is completed so you would execute your code at the right time.
