Graphics Output

[SureshAbraham]

I have Borland C++ free compiler installed on my MS windows platform. I can view the normal output window. However, when I try graphics like drawing a circle or arc, the output just disappears. How can I solve this?

You can write program under win32 platform, but it isn't easy. You can find some information about that. http://www.functionx.com/win32/

If you want to make GUI program "easily" I suggest the qtsdk + qdcreator.

http://qt.nokia.com/downloads at LGPL part.

i guess he is trying to draw graphics on console window, not in GUI form.

Perhaps we ought to ask what library he is using to draw graphics?

Is it the old Borland BGI library? How are you trying to draw the circles and arcs?

Hi,

Thanks for your response . I am using the console version. Our two friends have already suggested that only GUI form will work. Still, It used to work well with my old systems. I had run even simulations on that. Besides, no compilation or linking errors are reported. The screen is just turning base color. Is it some resolution problem? I have tried various resolutions also . Any way I am including my Graphics header(not complete) here. Help me out if you can.

Ah, yes, that's the old Borland BGI graphics.
If you are using Vista (or later, I think) then you are out of luck -- they won't work for you anymore.

If you still wish to use the BGI graphics, I suggest you check out the WinBGIm library.
http://www.cplusplus.com/forum/beginner/7409/
http://www.cplusplus.com/forum/beginner/11131/#msg52558

Otherwise, you'll want to use something like SFML, which is a very advanced library.
http://www.sfml-dev.org/
It has quite a learning-curve though. For what you are doing, you might want to stick with WinBGIm.

Good luck!
