Summary: The CopyIcon API

!!!!C# Signature:
 [DllImport("user32.dll")]
 static extern IntPtr CopyIcon(IntPtr hIcon);
!!!!VB Signature:
 <DllImport("user32.dll")> _
 Public Shared Function CopyIcon(ByVal hIcon As IntPtr) As IntPtr
 End Function
!!!!User-Defined Types:
None.

!!!!Notes:
Need to also include the following
[DllImport("user32.dll")]
 static extern IntPtr LoadCursor(IntPtr hInstance, int lpCursorName);

!!!!Tips & Tricks:
CopyCursor reference will fail at runtime, according to documentation it is a macro:
#define CopyCursor(pcur) ((HCURSOR)CopyIcon((HICON)(pcur)))
That means: instead of CopyCursor use CopyIcon instead.
Please add some!

!!!!Sample Code:
 private static string BusyCursorIcon { get; set; }
 private static string DoneCursorIcon { get; set; }

private const uint OCR_NORMAL = 32512;
 private const uint OCR_WAIT = 32514;

[DllImport("user32.dll", SetLastError = true, CharSet = CharSet.Auto)]
 private static extern IntPtr LoadCursorFromFile(string lpFileName);

[DllImport("user32.dll", SetLastError = true, CharSet = CharSet.Auto)]
 private static extern IntPtr CopyIcon(IntPtr hcur);

[DllImport("user32.dll", SetLastError = true, CharSet = CharSet.Auto)]
 private static extern bool SetSystemCursor(IntPtr hcur, uint id);

string folderPath = Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location);
 BusyCursorIcon = Path.Combine(folderPath, "aero_busy_xl.ani");
 DoneCursorIcon = Path.Combine(folderPath, "arrow_m.cur");

if (!File.Exists(BusyCursorIcon) || !File.Exists(DoneCursorIcon))
 {
   // AB: use api only to change cursor; same call will switch cursor!
   SetSystemCursor(LoadCursor(IntPtr.Zero, OCR_WAIT), OCR_NORMAL);
 }
 else 
 {
   IntPtr cursor = (working)  
        ? LoadCursorFromFile(BusyCursorIcon) 
        : LoadCursorFromFile(DoneCursorIcon);
   if (cursor != IntPtr.Zero)
     SetSystemCursor(CopyIcon(cursor), OCR_NORMAL);
   else
     SetSystemCursor(LoadCursor(IntPtr.Zero, OCR_WAIT), OCR_NORMAL);
 }

!!!!Alternative Managed API:
Do you know one?  Please contribute it!
