How do I find out what the windows constants like WM_MOUSEMOVE and WM_MOUSEDOWN are if I'm using C#?

interop

I'm writing some code that uses some unmanaged calls into user32 functions such as SetWindowsHookEx, etc.

This requires me to use lots of constants that I'm not sure what their value is. For example, if I want to set the hook as a low-level mouse hook I need to know that WM_MOUSE_LL = 14.

Where can I look these up?

I need to know what WM_MOUSEMOVE, WM_MOUSEDOWN, and more are. When I'm dealing with interop code, what is the easiest way for me to find these? Is it possible for me to import them into C# so they will be defined?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
