I'm still a C++ newbie who has only recently learned some file manipulation. I looked it up online and the codes given are way beyond my current skill. Is there a simple way to do this, or are there any good tutorials that can explain this from the very basics?
In windows look at the following API:
An extensive discussion can be found here. Obviously this topic is strongly operating system related. And if you are using some framework (ie MFC/ATL) you generally find some helper infrastructure. This reply refer to the lowest API level in WIndows. If you are planning to use MFC have a look here, if you prefer ATL look here.
There is no cross-platform way to do this in C++
Now that we have that out of the way, Felice Pollano's answer provides the Windows API so you can manipulate the clipboard in Windows.
Apple provides an example application named ClipboardViewer and an entire reference to the NSPasteBoard and the functionality it provides.
As for Linux, it depends on what windowing manager you are running.
There is a cross platform way to do this in C++, provided you are willing to use the Qt Library.
A solution for this is provided here:
If you are looking for a simle way to do this : simulate the keyboard combination ctrl + v and you are done with it. On all platforms.
