Thanks a ton,

The standard library does not provide any means of doing that. Thus, you
will want to use a third-party library. There is a C++ library FAQ
somewhere out there on the internet (it used to get posted here regularly,
but I do not recall seeing it recently).

Details of third-party libraries are off-topic in this group. Your best bet
would be a news group of forum dedicated to the particular target platform
of your application.

Read

http://www.codeproject.com/aspnet/webcamimage.asp

http://www.planet-source-code.com/vb...1339&lngWId=10

and adapt that code to C++. In Linux/FreeBSD, you could read some open
source projects code, it would be more easy.

I know the norms' group but I don't agree. Why doesn't help him?
If you don't like off-topics threads, just don't read them. I think we
can learn from them too. Why no?

ps. forgive my english

He is helping him, and others too. He helps the OP by telling him that
this is off topic in this group, so the next time the OP has a
question he/she can more easily decide if this group is appropriate or
not. Further he pointed the op to the library FAQ, which might help
the OP to find information that he/she needs. And third, he tells the
OP that it would be better to ask the question in a group specific for
his platform where more people with the knowledge he needs might be
found.

Further it helps others by keeping this group clean so that when you
or someone else have a C++ language question you can post it here
knowing that there are people reading and answering questions. If the
noise-ration is to high those experts who we depend on will go some
other place and it will be more difficult to get answers to our
questions.

And, by posting the question in the correct group the chance that
someone with the same problem will find an answered question by
searching increases.

The easy way to turn off automatic updates for Windows 10/11

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
