The usual way to do this is to provide a thread function (usually a static member function of your class) and to start a worker thread (since this seems to be an MFC app, with AfxBeginThread), passing the address of the thread function. However, this has been discussed countless times here in the forums - just do a search. Also see the following FAQs:Quote:

It basically shows a progressControl going from left to right.
In the working thread loop you can easily fill in his scanDir - mainloop.
If any more questions feel free to ask. When you have integrated it into your programm test every sort of terminating to be sure you didn't get any memory leaks, which may occure if the thread isn't terminated correctly too.

:D That's an interesting approach to avoiding memory leaks...Quote:

}
The condition given to this while statement doesn't seem right. It appears the condition currently is:
"while (the end of file == true) OR (Scanning is not equal to false)".
(i don't know, your 1st condition (EndOfFile) might be correct.)
To be clearer, I think it should be:
while (!EndOfFile && Scanning == TRUE)
So, it should be: while( we're not to the end of the file AND Scanning equals true), then: it's okay to continue the operation.
Also, as mentioned, it could be that ScanDir() is so busy repeating this operation, that time isn't available to process that button click.

You are totally right. In the oiginal whilestatement the loop was only done by (Sanning!=FALSE) because EndOfFile normally is FALSE as long as its not on the end. So it would never end when its not stopped from outside, because it could not be set to False because the loops in the OnScan() Statement itself didn't allow to be called again. This Method was still busy. But the mainproblem is as I described before its all one thread and VCC isn't VB where you work with DoEvents() to allow other calls in between. When you look into my file you will see an example. I did a Static counter variable and a separte thread which counts slowly up.This counting is shown by a CProgressCtrl. The value exchange between the thread and the CProgressCtrl is triggered by a timer. Also I did a start button which changes into a stop button and a rest ( wait ) button which changes between rest and continue. ( in German rest and break and wait are similar we say 'pause' or 'paused for that. I dont know which term normally is used in English. So basically it should be very easy to put a correct ScanDir() loop in which should usea Statement like you wrote.Quote:

Hey all,
I am really happy to see all of your replies. I am very happy that every one takes so much concern about my problem. Really nice to see it. And hey JonnyPoet, thank you very much for the reply and I thank you, for not only giving me the solution also for providing me a sample program. Now I am gonna ask so many questions, which I feel worth and sharing all your ideas. I am basically a Information Assurance engineer and I am making a small Security analysis tool. I am gonna implement all your tips and ideas, then i will come, whether it worked out or still we gonna do some work... :) .. Thankx all.
-Regards

if any questions in doing all that stuff everytime feel free to ask, you are welcome. Its totally fine not to be a professional in that, for example I'm just on the way studying VC++ in the first year. So some things like that are a good training for me. ;)Quote:
