thanks for the link. useful.

1. And what are the reasons you "can not use worker thread for this function"?

need something more deterministic. The thread operation does not quite sync with operation in the library...

Have a function as part of a dialog class which has some loops and so on and works. But during its run, the dialog needs its controls , etc. refreshed and update. For reasons can not use worker...

1. yes, this thread simply returns. No even driven exit is used.
2. Like may typical examples, this library is Initialized for providing callback function. library has exit routine that gets called...

the thread includes a series of steps till it returns. The first step is to initialize the library. I moved it out of the thread and seems to resolve it. Not 100% sure yet. Need to do more testing....

this is the code i use to check for thread exit.

void CMyDlg::OnBnClickedButton()

How many threads are started in your application?

in one of the tabs only when a button is clicked on.

Does the every tab dialog start the thread?

click on a button

How did you check...

only one thread get started in one of the tabs by clicking on a button. the rest are regular buttons.

my application is multi tab application which uses tab tree control. The APPCRASH may not be related to start of the thread. I could not see any memory lean risk code. I use CREATE for each dialog in...

this is the way I start my thread and get going to the end.

I have not dealt with threads and got stock with writing an app for data acquisition experiments.

why you do not use std::threads?. What are other alternatives based on your experiences?. Specially for passing array of objects to it in C++. I read _beginthread(ex) are appropriate for C++.

This is what I mean?. Condition variables versus events.. ?
https://en.cppreference.com/w/cpp/thread/condition_variable

how about condition variables versus events?. Both work at kernel level?. Which is more proper to use?.

need examples of a proper way to wait for a flag change in another thread without blocking the events?. In C++/windows.

thank you 2kaud and others.

Is there a reason why the SetThreadPriority is removed by 2Kaud?. Maybe it is not genuine c++?? may actually run faster without it??.
