I am a complete novice in OpenGL ES. OpenGL I know myself a little bit.
I use Windows7. I installed Microsoft Visual Sudio 2005 and the ARM emulator.
The examples on the Internet are categorized by Android, iPhone, etc.
1) Can I use only the examples for Windows, or all?
Unfortunately, the Windows examples that I've found, do not run on my PC. In one example, it is enough to call the command 'run' in Microsoft Visual Sudio 2005. In another Microsoft Visual Sudio 2005 Command Prompt is needed.
2) What is the difference?
3) Which project in Microsoft Visual Sudio 2005 is necessary?
4) Can someone give me a brief introduction? Neither the network nor in books I can find something to the very first steps to work with OpenGL ES.

Best regards
