如何实现Picture的打印
RT
希望把Picture控件一点不变的打印出来,有没有比较简单直接的方法
比如如果我在Picture上放一个Grid,希望出来的样子和看到的样子一样

如何将PictureBox中的图形与控件一起转换为BMP图
下面的方法实际上是抓取屏幕图象的方法。
如果要得到一个PictureBox中的图形（不包括覆盖在其上的控件），可以使用SavePicture Picture1.Picture "c:\test.bmp"语句将图形存盘。这种方法不管整个图形部分是否可见，都可以保存下来。
如果要包括覆盖在其上的控件，可以用下面的办法：
首先建立一个模块，输入以下内容：
Private Type PALETTEENTRY
peRed As Byte
peGreen As Byte
peBlue As Byte
peFlags As Byte
End Type
Private Type LOGPALETTE
palVersion As Integer
palNumEntries As Integer
palPalEntry(255) As PALETTEENTRY ' Enough for 256 colors.
End Type
Private Type GUID
Data1 As Long
Data2 As Integer
Data3 As Integer
Data4(7) As Byte
End Type
#If Win32 Then
Private Const RASTERCAPS As Long = 38
Private Const RC_PALETTE As Long = &H100
Private Const SIZEPALETTE As Long = 104
Private Type RECT
Left As Long
Top As Long
Right As Long
Bottom As Long
