Can a variable be passed to a shader in XNA?
Its one of the first things you learn about shaders when using them with XNA that you can pass on variables from C# to the shader code via the Effect.Parameters function. For example: In the above line, you’re sending the value stored in ‘someValue’ to the shader variable ‘shaderVariable’ ..
What is the entry point of shader in Win32?

Is it possible to get output from a shader?
The only real way to get output from a shader is via the image that it eventually outputs (GPGPU aside). But – if all you want to do is shader debugging, use PIX in the DirectX SDK. The graphics pipeline will only ever go forwards, CPU -> Vertex -> Pixel -> Frame.
