如何打印PictureBox中的所有控件

添加另外一个PictureBox，然后：
Private Const WM_PAINT = &HF
Private Const WM_PRINT = &H317
Private Const PRF_CLIENT = &H4&
Private Const PRF_CHILDREN = &H10&
Private Const PRF_OWNED = &H20&
Private Const PHYSICALOFFSETX As Long = 112
Private Const PHYSICALOFFSETY As Long = 113
Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd _
As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long
Private Declare Function GetDeviceCaps Lib "gdi32" (ByVal hdc As Long, ByVal nindex _
As Long) As Long
private Sub Form_Load()
  Picture1.AutoRedraw = True
  Picture2.AutoRedraw = True
  Picture2.BorderStyle = 0
  Picture2.Visible = False
End Sub
Private Sub Command2_Click()
  Dim retval As Long, xmargin As Single, ymargin As Single
  Dim x As Single, y As Single
  x = 1: y = 1
  With Printer
    .ScaleMode = vbInches
    xmargin = GetDeviceCaps(.hdc, PHYSICALOFFSETX)
    xmargin = (xmargin * .TwipsPerPixelX) / 1440
    ymargin = GetDeviceCaps(.hdc, PHYSICALOFFSETY)
    ymargin = (ymargin * .TwipsPerPixelY) / 1440
    Picture2.Width = Picture1.Width
    Picture2.Height = Picture1.Height
    DoEvents
    Picture1.SetFocus
    retval = SendMessage(Picture1.hwnd, WM_PAINT, Picture2.hdc, 0)
    retval = SendMessage(Picture1.hwnd, WM_PRINT, Picture2.hdc, _
    PRF_CHILDREN + PRF_CLIENT + PRF_OWNED)
    DoEvents
    Printer.Print ""
    .PaintPicture Picture2.Image, x - xmargin, y - ymargin
    .EndDoc
    End With
End Sub
