---this is my .cpp file.

I must assume that, you are using Qt Mobility , and some part of your code doesn't work. i could try to help you if you share more details or code.

[Rahul Das]

sorry, my previous post wasn't timely.pls Ignore it.

[kuheylan]

Thank you so much.
I am using OQ creator and this project is console app. I am sending my .pro file.

anybody help me. it is very important for me

[kuheylan]

when this .cpp file is written in console app. , it gives "exited with code 0" message. But when this .cpp file is written in empty file , it gives "exited with code -1073741511" message. why!!

[Rahul Das]

Frankly, i don't know much about openCV. Anyway, exited with 0 is the result of @ return 0;@ in your main(). And That means ,successful completion of the execution.

And what does Qt do in your application ?

EDIT : Just noticed : in your pro file, @LIBS += C:/opencvbuild/install/bin/*.dll@ I am bit doubtful about this part. I am not sure,wildcard can be used in here.

[kuheylan]

in console application! ...

[Rahul Das]

yes, i know its a console application. But this is not really a Qt application right? i mean,Not a Qt-console application. I couldn't find usage of Qt APIs anywhere in codes

But my friend used this code in qt and he says that it runs and camera runs. you are right it is not really a qt app. I found it

[andre]

Please kuheylan, calm down a bit. Don't flag your message as urgent, even if it is for you. It is hard for people to guess what is going wrong in your code, especially if they don't see it.

Your code does not look like real Qt code to me. Normally, Qt code creates a Q(Core)Application, calls exec() on that, and only exits when the eventloop is terminated. You are just creating a loop of your own, and I fail to see the connection between Qt and your code. Your code doesn't use a single Qt class. Perhaps you should ask your question in an OpenCV channel?

So... It is not even your code, but something you found off the net and your friend states works, and now you expect us to support it and help you figure out what it is doing? Sorry, it doesn't work like that. Please do your own homework.

Moved to the General forum, this seems to be the least inappropriate one for this.
