How to disable shaders?

[Flying_sands]

I want to render the scene with 2 passes. In the first pass, I want to render with shader. But in the second pass, I want to render the scene with fixed function. So, how to disable the shader? I use glDeleteObject, but it does not work.

glUseProgramObject(0);

If you mix shaders and fixed function in multipass rendering, make sure to remember that your shaders all use ftransform() to assure position invariance.
