Not with C++. Now if you were interested in some Windows API, there probably is. What did you have in mind?

Hi
I just tried to call Sleep(1000) in a thread function
But when i tried to

Unit threadFun(LPVOID lparam)
{
while(1)
{
Sleep(1000); // When tried to give break point over here appliacation gets terminates
............
}

}

Can any one give me solution to this

Thanks

Remove the call to Sleep(). It's almost always unnecessary and usually indicates a design flaw.

But i need a Sleep() function over there.
Because i need a function to be get called every 1000 milliseconds

Then use SetTimer(1000).

Remember that Windows is not a real-time system, your function might or might not be called at every 1000 milliseconds, depending on what's happening on the OS.

I don't see why should the application "terminate" with this piece of code. (It might have probably helped us if you had given the remaining code within the thread function to see if anything is wrong)

With more than one thread running, may be the issue is somewhere else? Besides that, like David said, remove the unnecessary Sleep call and replace it with something that makes sense of some sort.

does the application terminate or does it hang?
i would thing that statement would cause the app to hang... continuous loop with a defined wait time.. is that 1000 seconds or milliseconds it's library specific..??

I use Sleep() all the time in threaded code, there's no reason it should cause the termination in and of itself.

However, the thread code you show runs in the context of a larger program, notably the main thread which created the thread you show. What is that thread doing? If it exits, it will take the created thread down with it.

Make sure the main code is waiting for this thread to terminate before it does.

do you mean, it is getting terminated when you try to debug?

Please prefix your main thread subject with [SOLVED] if it is solved.

I just added
WatiForSingleObject(threadHandle,INFINITE)
now working fine. Can any one tell why does it so

My answer above told you exactly why WaitForSingleObject() solved the problem

However, the thread code you show runs in the context of a larger program, notably the main thread which created the thread you show. What is that thread doing? If it exits, it will take the created thread down with it.

Isn't it just an XML-type file? Regardless, just use Excel Automation and let Excel handle the details for you.
