Compile it in VB as a .scr and create setup disks with the plain VB setup wizard. After installing it on the Pc's you will be able to use it like a standard screen saver.

Hope this helps.

I tried out with that. It works just fine like a screen saver. Actual problem is I also could not able to show the preview to be displayed.

Thank you, Veroland. But I want to know how to make this by myself. I know That's possible using Bitblt function. The first parameter of this function is the destination of a Bitmap, or better, the preview. But I didn't discover what is this first parameter! And the password button, i just can't enable it.

Here are the functions you would need to allow you to hit the Preview button and use the Password Option.

You must call CleanExit on a mousemove or keypress event.

Declare Function VerifyScreenSavePwd Lib "PASSWORD.CPL" () As Long
Declare Function PwdChangePassword Lib "MPR.DLL" Alias "PwdChangePasswordA" (ByVal lpProvider As String, ByVal hWnd As Long, ByVal dwFlags As Long) As Long

Sub Startup()
   
  ' This routine initializes the entire program.
  ' It is called once - at program start, after the main form is loaded
  ' and the check for other copies has been done
   
  On Error GoTo Startup_err   ' try to handle errors cleanly
  Data_Dir$ = App.Path        ' default data dir of where the .scr is, otherwise
  ' the open dialog box will have nothing.
   
  CallingArguments$ = Command$    ' save the calling arguments to the program
  ' the calling arguments can be:
  '       /p = inside the preview window
  '       /c = options button selected
   
  If Left(CallingArguments$, 2) = "/p" Then ' called from inside the preview window
   
    Call PreviewDisplay
 
  End If
   
  ' if it was not inside the preview display then either the program was called
  ' or the setup was called, either way we need to get the config info
   
  Call GetINInfo      ' Get the necessary info from the .INI file
   
  If CallingArguments$ = "/c" Then    ' options button pressed, show setup dialog
       
    Setup.Text1.Text = Data_Dir$
    Setup.Show 1
 
  End If
   
  ' if got here then a normal program start
  lx = ShowCursor(False)  ' hide the cursor
  Main_Form.Show           ' show the maximized main screen
  gMouseX = -1            ' set mouse value so mousemove routine will know what to do
  gMouseY = -1
   
  Exit Sub

Startup_err:          ' an error occured, exit cleanly
            CleanExit
           
End Sub

Public Sub PreviewDisplay()
 
  ' this routine displays a form in the little screen saver preview display
  ' note: code based on source by Jeff Hack
   
  ' the preview window handle will be in the right 3 chars of the calling arguments
  Dim Temp%, PrevHWND As Long
   
  ' note we don't show the "Main_Form" here as it tries to maximize itself
  ' against the entire screen and besides a mouse move/key press could end the
  ' display instead of clicking on a button.
   
  PrevHWND = CLng(Right$(Command$, Len(Command$) - 3))
  Temp% = SetParent(PreviewForm.Picture1.hwnd, PrevHWND) 'set active window to the preview window
 
  ' show the graphic in the window, this is a static display but
  ' a active one could be done here
  PreviewForm.Picture1.Left = 0
  PreviewForm.Picture1.Top = 0
  DoEvents        'allow Windows to check for other events
 
  Do While IsWindowVisible(PrevHWND) <> 0 ' wait around until the window dissapears (ok or cancel)
   
    DoEvents  'allow Windows to check for other events
 
  Loop
   
  End
   
End Sub

Sub CleanExit()
   
  If InCleanExit = False Then
   
    InCleanExit = True
   
    If VerifyScreenSavePwd = 1 Then
   
      ' this routine exits the program cleanly
   
      ' turn the cursor back on
      lx = ShowCursor(True)
     
      ' Turn back on Windows desire to start another screen saver
      lx = SystemParametersInfo(SPI_SETSCREENSAVEACTIVE, 1, ByVal 0&, 0)
   
      InCleanExit = False
      ' note, optionally put in a error dialog box here.
      End
   
    End If
   
    InCleanExit = False
   
  End If
 
End Sub
