I search a lot of on internet but didn't find some good copy-paste manager for windows 7. I want to make something to easy copying multiple texts. So my question is what function to use in c++ to select some text that will be copy. The plan is that every time when is pressed CTRL+C selected text copy to some txt file, and when is pressed CTRL+V application show you what is in that file, and you can use what text you need. The main question is how to select text, what function to use? Platform win 7.
You should read up a bit on how the Windows clip board works. Every application in the system can place objects of different formats (including text) on the clip board. The easiest way to grab the content out of any applications is probably to somehow monitor the clip board and get the data from there.
For the pasting part, if I remember correctly, there is a special kind of "owner-handled" data on the clip board. Using that, the data isn't actually published on the clip board, only a reference to the application currently having the clip board data. Whenever the data is pasted the application gets notified that it should send the data to the recipient. It should be possible to exploit that functionality to get your application to pop up a windows where the user can select what data to paste.

I've used Qt for widget development a fair bit. That's straightforward. But how could I write a program that can be invoked from anywhere on Windows?
Say I've selected some text in a web browser. I want to be able to invoke my program via keystroke, maybe show a little list containing a list of text files I can select (ideally where the cursor is), and then add the selected text to that file.
How can I do this?
I suggest you to have a look at:

This is a very random and maybe a bit strange question that i thought of at 3AM. I was thinking about how code could make my day to day life easier. Every morning I wake up, open chrome to the facebook conversations with my boyfriend, and write "good morning". And thats when i thought about this hypothetical project(just out of curiosity, I wouldn't use it haha): making a code that i can just run that does all of this for me.
I could have a html file that could redirect to the facebook link(https://www.facebook.com/messages/t/boyfriend_name). But how would I go on to make the code open this file, then move the mouse to where its supposed to go (the white area where the user inputs the text) then insert the text then press send?
I'm not asking for any code help as I can imagine that is too much, but my question is: could this be achievable in C++?(This is what we've been studying at school so far). If not, what coding language should I use? Is the idea achievable without a vast knowledge in computer science? If yes, have you got any sources about opening files using C++, moving cursor etc.
Note:The OS this would happen on is Windows 10
To do what you want is possible by using AutoIT and to use it from C++ you can try AutoITX for C++. With AutoIT it's possible to detect windows, move the mouse and insert text, although a web page is like a blackbox to it, so you'll have to rely on relative pixel coordinates (it might not be very robust).
My objective is to create a game playable in the Linux terminal. However, there is a concept that I don't know how to name, so my searches are coming up empty handed.
How do programs like iptraf access the output on such a low level that they can modify the background, foreground and character content of each cell as well as capturing all keyboard input instead of the shell?
I assume that somewhere, there exists a 2D array that can be modified to display custom terminal window content, but I can't name this concept so I can't search for it. What concept am I describing?
As per the idea of this meta-answer, I'm answering this question so that i will get removed from the "unanswered" listing.
The concept you are looking for was described by #123, it's called ncurses.
I'm curious to know how you can draw/update a certain region of the terminal/console. Is there any cross-platform libraries to do so?
The reason I want to know is because I am developing an instant message command line application, and I was curious to know how I can update the message viewer (where all the messages go) separately to where you write commands/text for other people in the chat. Obviously if I just tried to get input and write to cout then the input the user is entering and the messages would be "interfered" (by interfered I mean split in multiple lines).
I was thinking of using two stream objects: one to store the view (messages/output from the server) and one to store the input from the user, and just redraw whenever required. However, this seems inefficient and it requires me to clear the screen (in which case I don't know how to clear the screen efficiently and in a cross-platform manner).
I was also thinking of just switching to Qt/wxWidgets as it might simpler to make a GUI.
Use ncurses library to write text-based user interfaces in a terminal-independent manner.
As suggested by #Naruto, ncurses is a good way to go. At a much more basic level, you can also just use ANSI escape codes to move the cursor around the screen too:
For example, to position the cursor at line 5, column 23, you can enter this
echo -n "\033[5;23H"
There are more examples here.
At user request, my (for now C#) application reads big chunks of rich text (for now, in .NET FlowDocument XAML format) from a SQL Server database, and displays it.
I use a C# RichTextBox for that, it works but the whole thing is much too slow (the whole application is not very responsive). I want to remake everything in native C++.
What is the best way to get fast rich text rendering in Windows 7?
I would welcome suggestions
1) on the text API to use (Direct2D/DirectWrite or GDI or something else? use glyphs or higher level functions?),
2) also on how to store the rich text in memory to accomodate scrolling up and down the flow of text, insertion in the middle of the text etc.
Thanks.
