Public Class FullscreenClass



Public Declare Function SetWindowPos Lib user32.dll Alias SetWindowPos(ByVal hWnd As IntPtr, ByVal hWndIntertAfter As IntPtr, ByVal X As Integer, ByVal Y As Integer, ByVal cx As Integer, ByVal cy As Integer, ByVal uFlags
As Integer) As Boolean 



'You also need an alias to the API function called GetSystemMetrics, like this : 
 Private Declare Function GetSystemMetrics Lib user32.dll Alias GetSystemMetrics (ByVal Which As Integer) As Integer


'Following this you need to declare 4 constants : 
    Private Const SM_CXSCREEN As Integer = 0
    Private Const SM_CYSCREEN As Integer = 1
    Public Shared HWND_TOP As IntPtr = IntPtr.Zero
    Public Const SWP_SHOWWINDOW As Integer = 64


'Then 2 public properties : 

Public ReadOnly Property ScreenX() As Integer
       Get 
           Return
        GetSystemMetrics(SM_CXSCREEN)
       End Get
End Property


Public ReadOnly Property ScreenY() As Integer
        Get
            Return
        GetSystemMetrics(SM_CYSCREEN)
        End Get 
End Property 


Public Sub FullScreen(ByVal frm As Form, ByVal boolTopOptional As Boolean)

        frm.WindowState = FormWindowState.Maximized
        frm.FormBorderStyle = Windows.Forms.FormBorderStyle.None
        Me.TopMost = boolTopOptional
        SetWindowPos(frm.Handle, HWND_TOP, 0,0, ScreenX, ScreenY, SWP_SHOWWINDOW)

End Sub

End Class      

--------------------------------------------------------------------------------- Updated Making fullscreen using Screen class

Public Class classFullScreen
    Dim varScreen As Screen
    Dim intWidth As Integer = Screen.PrimaryScreen.Bounds.Width
    Dim intHeight As Integer = Screen.PrimaryScreen.Bounds.Height
    Dim intTop As Integer = 0
    Dim intLeft As Integer = 0
    Dim intX As Integer = 0
    Dim intY As Integer = 0

    Public Function FullscreenTheForm(ByVal frm As Form)
        frm.Top = intTop
        frm.Left = intLeft
        frm.Width = intWidth + 40
        frm.Height = intHeight
        frm.FormBorderStyle = FormBorderStyle.None


        Return 0
    End Function
End Class

Now problem is -> The bottom window bar is above on form.I'm trying to resolve this issue also. Thank you mav and robert for your comments.
