Centering a form using API

Hi, can anyone point me in the right direction for centering a form using API.

the reason for this is, I'm using VBA and it doesn't recognise the screen function

thanks in advance

This will get the screen size:

Code:

---

Private Declare Function GetSystemMetrics Lib "user32" (ByVal nIndex As Long) As Long
Const SM_CXSCREEN = 0 'X Size of screen
Const SM_CYSCREEN = 1 'Y Size of Screen
Me.Print "Screen X:" + Str$(GetSystemMetrics(SM_CXSCREEN))
Me.Print "Screen Y:" + Str$(GetSystemMetrics(SM_CYSCREEN))
'center it then

bucko, what you need to use the API?

Code:

---

Option Explicit
Private Declare Function MoveWindow Lib "user32" (ByVal hwnd As Long, ByVal x As Long, ByVal y As Long, ByVal nWidth As Long, ByVal nHeight As Long, ByVal bRepaint As Long) As Long

Private Sub Form_Load()
    Dim NewX As Long
    Dim NewY As Long
    Dim NewW As Long
    Dim NewH As Long
   
    NewX = ScaleX((Screen.Width - Me.Width) \ 2, vbTwips, vbPixels)
    NewY = ScaleY((Screen.Height - Me.Height) \ 2, vbTwips, vbPixels)
    NewW = ScaleX(Me.Height, vbTwips, vbPixels)
    NewH = ScaleY(Me.Height, vbTwips, vbPixels)
    MoveWindow Me.hwnd, NewX, NewY, NewW, NewH, True
End Sub

or you can archieve this without the API

Code:

---

Private Sub Form_Resize()
    If Me.WindowState <> vbMinimized Then
        Me.Left = (Screen.Width - Me.Width) \ 2
        Me.Top = (Screen.Height - Me.Height) \ 2
    End If
End Sub
