如果是API函數的話，調用時要先封裝，例如：
Const LR_LOADFROMFILE = &H10
Const IMAGE_BITMAP = 0
Const IMAGE_ICON = 1
Const IMAGE_CURSOR = 2
Const IMAGE_ENHMETAFILE = 3
Const CF_BITMAP = 2
Private Declare Function LoadImage Lib "user32" Alias "LoadImageA" (ByVal hInst As Long, ByVal lpsz As String, ByVal dwImageType As Long, ByVal dwDesiredWidth As Long, ByVal dwDesiredHeight As Long, ByVal dwFlags As Long) As Long
Private Declare Function CloseClipboard Lib "user32" () As Long
Private Declare Function OpenClipboard Lib "user32" (ByVal hwnd As Long) As Long
Private Declare Function EmptyClipboard Lib "user32" () As Long
Private Declare Function SetClipboardData Lib "user32" (ByVal wFormat As Long, ByVal hMem As Long) As Long
Private Declare Function IsClipboardFormatAvailable Lib "user32" (ByVal wFormat As Long) As Long
Private Sub Form_Load()
Dim hDC As Long, hBitmap As Long
'Load the bitmap into the memory
hBitmap = LoadImage(App.hInstance, "d:\pintu\p1.bmp", IMAGE_BITMAP, 400, 290, LR_LOADFROMFILE)
If hBitmap = 0 Then
MsgBox "There was an error while loading the bitmap"
Exit Sub
End If
'open the clipboard
OpenClipboard Me.hwnd
'Clear the clipboard
EmptyClipboard
'Put our bitmap onto the clipboard
SetClipboardData CF_BITMAP, hBitmap
'Check if there's a bitmap on the clipboard
If IsClipboardFormatAvailable(CF_BITMAP) = 0 Then
MsgBox "There was an error while pasting the bitmap to the clipboard!"
End If
'Close the clipboard
CloseClipboard
'Get the picture from the clipboard
Me.Picture = Clipboard.GetData(vbCFBitmap)
End Sub

SizeToContent是不是自定義函數就不清楚了，如果是，可以直接Call SizeToContent(參數）就好了。
