User-Defined Types:

static readonly IntPtr HWND_TOPMOST = new IntPtr(-1);

static readonly IntPtr HWND_NOTOPMOST = new IntPtr(-2);

static readonly IntPtr HWND_TOP = new IntPtr(0);

static readonly IntPtr HWND_BOTTOM = new IntPtr(1);

ReadOnly HWND_BOTTOM As New IntPtr(1)

ReadOnly HWND_NOTOPMOST As New IntPtr(-2)

ReadOnly HWND_TOP As New IntPtr(0)

ReadOnly HWND_TOPMOST As New IntPtr(-1)

Notes:

HWND_TOP will bring a window to the front of the Z-Order only if the thread is in the foreground. Otherwise it will bring the window to the front of the thread's Z-order.
