I have a string with me and I wanted to find the size of box that is bounding the string.Is there any C++ API which can help me with it?
I know it can be done with GDI+.But I wanted a more better way using basic APIs
Using Gdi+ is an overhead as it would have to start Gdi+ and close it..So if i can obtain it directly without using GDI+
The lowest level function that one can think of is GetTextExtentPoint32 in Win32/GDI (C/C++ API).

I'm fairly new to c++ and was wondering if there is a way to figure out the canvas' size of another program?
For example, code something that will tell me the size and position of a program like Task Manager or CommandPropmt. Of course, they would have to be opened first.
It's quite easy to do this - get the window handle with FindWindow(), and then get the size of the window using GetWindowRect() or GetClientRect(), depending on which bit of the application window you want the size of. All these functions are part of the Win32 API and are fully documented online.

I intend to use OpenCV for a project in which I've already built the server in Go. However, OpenCV doesn't have a Go API, so what's the best solution? Call a c++ program with .exec, use swig, find another library to do computer vision?
Thanks.
Edit: I want to maximize performance, and I'm ok with C++.
SWIG is certainly a viable option.
You can also search for a Go binding to OpenCV. For example: https://github.com/lazywei/go-opencv

I have implemented a project in Windows using C++ that creates a timer queue, add entries to it, perform a callback function when the timer expires,waits for next timer, etc. It was possible using the Windows functions CreateTimer, CreateTimerQueueTimer, CreateTimer,etc.
Now my question is how to do the same thing in Linux using C++? Is there some API ? Is timer_create a good option for doing this? It will be much helpful if an example is also provided.
Can't you use libevent for this ?

I'm trying to write text-based gui. Is there a way to access terminal per pixel using pure C++? I read a one method, but it was SDL based ;[
Not sure what you imply by "Pure C++", but ncurses is the go-to library for CLI applications (and there is a port for Windows called pdcurses )

I've developed a MATLAB code that I think it is useful to be used by researchers. How can I embed it in a website to be used free?
It gets two integers and return a set of integers
Also it is possible to convert it to c++, If it helps.
Thanks
