How to use VS2008 express and DirectX to draw a circle?

[zmarcoz]

Just want to do some very simple graphics. Like a circle or a square. Any website teaches us how to do that? Thanks

Use trigonometric functions to draw the approximation of a circle ( you need to draw a regular polygon with many sides )

You'll never learn anything with websites, apart MSDN.
Why don't you see the dozens of MS samples from DirectX SDK ?!

..in that case, I will not have learnt that I will never learn anything with websites, so I can learn from websites and what I have learnt is that that is another crap comment brought to you by george135...

Seriously, george, why do you bother?

I am new to visual C++; could you please post the link of MSDN DirectX examples? I googled those keywords, but have could not find. Thanks

Ignore george135, the only keys he has on his keyboard are letters 'M' 'S' 'D' 'N' and Windows logo

To draw a (filled) circle with triangles:

Start a triangle fan
put the central vertex
iterate angles
    draw the vertex at centralX+radius*cos(angle), centralY+radius*sin(angle)

The DirectX samples are provided as part of the DirectX SDK and can be found in the folder:
<InstallDir>\Microsoft DirectX SDK (<SDKdate>)\Samples

The provided SDK documentation can be found in:
<InstallDir>\Microsoft DirectX SDK (<SDKdate>)\Documentation

Tutorials can be found in the Documentation at:
DirectX Graphics -> Direct3D X -> Tutorials and Samples

The provided SDK samples and documentation are pretty good, but there's still plenty that can be learned online as well. Claiming otherwise is just assinine.
