Sample Code:

Here's the data structure for the NotifyIconData block, contributed by staff at http://www.softswift.com

    [StructLayout(LayoutKind.Sequential)]
    public struct RECT
    public struct NotifyIconData
    {
        public Int32 left;
        public Int32 top;
        public Int32 right;
        public Int32 bottom;
        public System.Int32 cbSize; // DWORD
        public System.IntPtr hWnd; // HWND
        public System.Int32 uID; // UINT
        public NotifyFlags uFlags; // UINT
        public System.Int32 uCallbackMessage; // UINT
        public System.IntPtr hIcon; // HICON
        [MarshalAs(UnmanagedType.ByValTStr, SizeConst=128)]
        public System.String szTip; // char[128]
        public System.Int32 dwState; // DWORD
        public System.Int32 dwStateMask; // DWORD
        [MarshalAs(UnmanagedType.ByValTStr, SizeConst=256)]
        public System.String szInfo; // char[256]
        public System.Int32 uTimeoutOrVersion; // UINT
        [MarshalAs(UnmanagedType.ByValTStr, SizeConst=64)]
        public System.String szInfoTitle; // char[64]
        public System.Int32 dwInfoFlags; // DWORD
        //GUID guidItem; > IE 6
    }

    [StructLayout(LayoutKind.Sequential)]
    public struct NOTIFYICONIDENTIFIER
    {
        public uint cbSize;
        public IntPtr hWnd;
        public uint uID;
        public Guid guidItem;
    }

    [DllImport("shell32.dll", SetLastError = true)]
    private static extern int Shell_NotifyIconGetRect([In]ref NOTIFYICONIDENTIFIER identifier, [Out]out RECT iconLocation);

    public static RECT GetNotifyIconRect(IntPtr windowHandle, uint taskbarIconId)
    {
        var rect = new RECT();
        var notifyIcon = new NOTIFYICONIDENTIFIER();
        notifyIcon.cbSize = (uint)Marshal.SizeOf(notifyIcon.GetType());
        notifyIcon.hWnd = windowHandle;
        notifyIcon.uID = taskbarIconId;
        var hresult = Shell_NotifyIconGetRect(ref notifyIcon, out rect);
        if (hresult == 0x80004005)
        {
            // E_FAIL, will happen if the icon is not there.
            throw new Win32Exception(hresult, "Failed to get icon position.");
        }

        if (hresult != 0)
        {
            throw new Win32Exception(hresult);
        }

And then we noticed that the data structure is already provided elsewhere on this site but without a reference so here's the reference http://www.pinvoke.net/default.aspx/Structures.NOTIFYICONDATA

        return rect;
    }

Notes:

None.
