Loop executing one thread

[sunny_sz]

Hello everbody :

I am doing my app , and I want to loop executing one thread , I know how to start a thread , but do not know how to loop executing one thread without using OnTimer() .

Say :

There is a thread for displaying current time in my edit box , now what i want is : when I click on one button to start thread and loop executing displaying current time(that's to say : always displaying update local time in my edit box) , once click on stop button , will stop thread and stop update current time .


Could anyone give me any code snippet ??

Thanks here beforehand .

You could create a global variable bool bStop = false; and set it to true if you want to stop the thread.

Thread function could look like this:
DWORD WINAPI ThreadProc(LPVOID lpParameter)
{
while(!bStop)
{
UpdateTimer();
Sleep(1000); // Replace 1000 with the update interval
}
return 0;
}

If there are two thread in my project , and I want the two thread to run synchro , and now how to realize that ?(without using OnTimer()).

Could you pls. help me out of that ?

Thank you once again !

Now I don't understand what you mean. I thought you had your main thread (the one which always exists) and now wanted to create a new using CreateThread() for updating the timer. I gave you the code for its thread function.
Do you now want to create another thread? What should this thread be doing?

Sorry for not detailed description .

Provisionally , forsake the case above , assume that there are two threads in my another project , when I click on "Run" button to start the two threads(they are running synch.) Now what i want is how to make the two threadings run synch .

Could you pls. help me ?

Anyway , thank you very much !
