static extern bool SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter, int X, int Y, int cx, int cy, SetWindowPosFlags uFlags);
VB.NET Signature:

C# Constants:
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);
VB.NET Constants:
Private ReadOnly HWND_BOTTOM As New IntPtr(1)
Private ReadOnly HWND_NOTOPMOST As New IntPtr(-2)
Private ReadOnly HWND_TOP As New IntPtr(0)
Private 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.
Alternative Managed API:
Use the System.Windows.Forms.Form.TopMost property.
