winforms

[DllImport("user32.dll")]
public static extern int SetScrollPos(IntPtr hWnd, int nBar, int nPos, bool bRedraw);
[DllImport("user32.dll", CharSet = System.Runtime.InteropServices.CharSet.Auto)]
public static extern int GetScrollPos(int hWnd, int nBar);

So those are the externs im using to move the scroll position, what im doing, is i get the current position, and add or substract an exact amount of pixels, and the scroll bar on my form moves perfectly how i want it, but the content in the control stays stationary. What is the problem here?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language.
