title: SetScrollPos: scroll bar moving, but control content not updating
body: <pre><code>[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);
  </code></pre>
  
  <p>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?</p>
