Tips & Tricks:

Please add some!

Sample Code:

SCROLLINFO scrollinfo = new SCROLLINFO();

scrollinfo.cbSize = Marshal.SizeOf( typeof(SCROLLINFO) );

scrollinfo.fMask = Convert.ToInt32(LPCSCROLLINFO.SIF_RANGE);

scrollinfo.nMin = 0;

scrollinfo.nMax = 4;

SetScrollInfo( MyControl.Handle, (int) SBTYPES.SB_VERT, ref scrollinfo, true );
