I would like to configure OpenFramework IDE in my codeblock. I want to build an app which prints the line on screen.
If the only thing you want is to just print a line of text you can use std::cout that prints to basic output onto your console window when the application runs. This is the most basic and easiest way to solve this.
If need to do something more complex than that, like program with GUI instead of console app, I would suggest you to use something other than OpenFrameworks, like f.e. Qt, that has a support for things like this. OpenFrameworks has the capability of doing all that, it just isn't it's main goal. You can download various addons that implement things like UI elemenets, but they are usually pretty simple.
Edit: I've just realized that by line you probably didn't mean a line of text...
Well, OpenFrameworks has no longer an Code Blocks support, you can still though download an older version from http://openframeworks.cc/download/older/

I want to make desktop application with cpp and make a completely new form and I don't want to use winforms or any external addons just cpp.
When presenting output to screen you almost always have to call some kind of system call at some point. So the next closest thing to winforms is probably the winapi, but you could try some kind of graphical library for example sdl2 or sfml which encapsulates these calls with their own api. But you wouldn't have all these nice native windows buttons and tabviews and scrollbars and textboxes and ... only some basic shapes, images and pixel buffers

I know that there are WYSIWYG editors available for GUI development, but are those the best way?
I know that in HTML if you use a WYSIWYG editor like Dreamweaver, what it produces will work but it will produce bad code that causes the program to not be as efficient as it could be.
Is it the same deal with C++ and other compiled languages?
Edit: I'll be developing for Windows 7. I probably wont be needing anything fancy like progress bars, just basic things like buttons, tick boxes, and a place to display output. It will just be running CMD commands based on what the user has selected before running it and displaying CMDs output in the program.
I guess the question I specifically wanted answered is whether it is best to "hand code" the GUI like you would in HTML, or if WYSIWYG editors are the way to go.

Hi Guys I was writing a web application which requires me to compile and execute code from within a browser. I am a little clueless about it though I read the following links to see how I can go about it.
http://www.quora.com/Interviewstreet/How-can-I-build-a-compiler-like-the-one-on-InterviewStreet-from-scratch
http://norvig.com/lispy.html
developer.hackerearth.com
I am planning to write it for several languages namely C/C++/java/python/Ruby
Any pointers would be helpful
You can just take the code and send it to server server will compile and execute the code and send back to the browser.
If you don't have much time.
If you have much time then you can build your own compiler like one you want and integrate it with you'r web application. like w3school and ideone.
or pass it to local host compiler it will execute and return the result to the browser.

Recently, I've been thinking about how there are multiple versions of linux and how they are all built on a similar kernel. And I was wondering if it was possible with Windows. In this case I am thinking of having the first program loaded after the kernel has booted up and started all the devices, would be the what pops up instead of the windows login screen.
The reason for this is because I was wondering if it was possible to have the system render all the objects on the screen in a distint styling, but still process it as if it were running on a normal windows machine.
Any Thoughts?
Initially I thought this was a naive question, but Mooing Duck's link in the comments proved insightful. There are projects that do just this: EmergeDesktop, SharpE, even the KDE.
They're open and on sourceforge, go get them and dink around to your hearts content.
I'm not sure that the login screen is part of the shell however. So your alternate shell would only show up after you log in.
However, in the long run, alternate shells have no hope of competition. Microsoft controls the environment and they don't play too nice with competition.

How would I go about coding a new Windows Vista Shell?
Everything you need to do as shell has never been documented, so there are some issues with file change notifications etc. The basics are:
SystemParametersInfo(SPI_SETMINIMIZEDMETRICS,...MINIMIZEDMETRICS) with (undocumented?) flag 8
Register as the shell (SetShellWindow,SetProgmanWindow,ShellDDEInit,RegisterShellHook etc)
Hide welcome screen by setting a signal ("msgina: ShellReadyEvent" and "ShellDesktopSwitchEvent")
Start registry run key, start menu\startup and ShellServiceObjects
Set registry Explorer\SessionInfo
The good thing is, you are not the first to write a new shell, if you look around, you can find some obscure required info. Here is a list to get you started:

http://xoblite.net/source/Blackbox.cpp.html
http://svn.reactos.org/svn/reactos/trunk/reactos/base/shell/
http://www.geoffchappell.com/viewer.htm?doc=studies/windows/shell/explorer/index.htm&tx=36
A good place to start would be investigating how to build a command line parser, something that can tokenize and interpret the inputs. There are tools that can help with this like ANTLR, or you might like to try building your own.
Once you've parsed the inputs you need to decide what actions to take - launching processes, piping between processes, redirecting output - and making those system calls.
If you're just after a more powerful shell rather than interested in building one, give PowerShell a try.
