how to program not in command promt
Author
I'm learning C++ and I know the basics of the language and can make text based programmes in command promt. But I want to start using grafics/polygons, I want to use a window for it but how do you do that. So I would like giudence for setting up a gui.
thanks in advance
The easiest way to start working with windows is to use something like SDL, 'specially if you want to use graphics (note the correct spelling) and polygons, since you can set up an OpenGL context with a few lines. If you plan on using D3D however, I did find some tutorials ages ago when I made a Google search, but I'm sure somebody can provide you with links if you have any trouble finding some.
Since you're learning C++, I'm going to suggest you try and read bitmaps without the help of APIs, since it'll teach you a fair bit when it comes to learning C/C++, and you can use the resulting code to load images for rendering.
A GUI on the other hand takes a bit more work. You can usually whip up something fairly simple fairly quickly, providing you have the basics (text rendering, etc.) already implemented. If you don't have anything, it can take a fair bit longer, or you can skulk around the net for a GUI that's already been implemented, but unless it's under a non-restrictive license (LGPL for example), you probably wont be able to use it in apps you plan on selling.

I will just add this, I use Dev-C++ that has a template for OpenGL. The thing is, I don't know how to use it
this is it
and how do I do a code box
this is it

[source][/source] for a source box like that. [code][/code] (note lowercase c) for fixed-width font, but no box or scrollbars. Generally for anything longer than a couple of lines you want [source].

Its probably better if you use sdl a lot less code and you don't have to deal with Windows API which is ugly as hell.
