Center picture in picture box (code needs polishing)

Hi,
TO TRY THE CODE: place a picturebox on a form and name it DOWN

I want to use picture box as a command button in order to avoid the focus rectangle when the regular command button is down.
To do that I draw edge at runtime around my picture box (see code below)

The button part works well (picture box looks like the button)

The only part I have trouble with is centering the picture in the picture box. I've got the code from Arron Young and it works on a picture box but when I combine it with my code to draw the edges around the picture box it doesn't center.

Anyway here's the code (the last sub - CenterPicture() is the one I want to use with the rest of my code.... so far unsuccessfully.

VB Code:

Private Declare Function DrawEdge Lib "user32" (ByVal hDC As Long, qrc As RECT, ByVal Edge As Long, ByVal grfFlags As Long) As Long
Private Type RECT
    Left As Long
    Top As Long
    Right As Long
    Bottom As Long
End Type
Private Const BDR_RAISEDOUTER = &H1
Private Const BDR_SUNKENOUTER = &H2
Private Const BDR_RAISEDINNER = &H4
Private Const BDR_SUNKENINNER = &H8
Private Const EDGE_RAISED = (BDR_RAISEDOUTER Or BDR_RAISEDINNER)
Private Const EDGE_SUNKEN = (BDR_SUNKENOUTER Or BDR_SUNKENINNER)
Private Const EDGE_ETCHED = (BDR_SUNKENOUTER Or BDR_RAISEDINNER)
Private Const EDGE_BUMP = (BDR_RAISEDOUTER Or BDR_SUNKENINNER)
Private Const BF_LEFT = &H1
Private Const BF_TOP = &H2
Private Const BF_RIGHT = &H4
Private Const BF_BOTTOM = &H8
Private Const BF_RECT = (BF_LEFT Or BF_TOP Or BF_RIGHT Or BF_BOTTOM)
 
Dim ButtonBorder As Long     ' picture variable to store Edge type
 
' Draw picture with edges at startup
Private Sub Form_Load()
  DOWN.AutoRedraw = False
  ButtonBorder = EDGE_RAISED       ' draw "button edge" around picture
End Sub
 
' This will make our picturebox look like a PRESSED button
Private Sub DnPressed()
  ButtonBorder = EDGE_SUNKEN
  DOWN.Refresh
End Sub
' This will make our picturebox look like a RELEASSED button
Private Sub DnReleased()
  ButtonBorder = EDGE_RAISED
  DOWN.Refresh
End Sub
 
' Simulate Command_MouseDown() & command_MouseUp()
Private Sub DOWN_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
  Call DnPressed
End Sub
Private Sub DOWN_MouseUp(Button As Integer, Shift As Integer, X As Single, Y As Single)
  Call DnReleased
End Sub
Private Sub DOWN_DblClick()
  Call DnPressed
End Sub
 
' Repaint drawn edges around our picture
Private Sub DOWN_Paint()
  Dim r As RECT
  DOWN.Cls
  r.Bottom = DOWN.ScaleHeight
  r.Right = DOWN.ScaleWidth
  DrawEdge DOWN.hDC, r, ButtonBorder, BF_RECT
End Sub
