The entire contents of the picture box to the clipboard

VB itself does not allow you a Form, UserControl or a PictureBox on a complete picture to the clipboard. If you use Clipboard.SetData, will only copy the bitmap object loaded. By using the API method, you can go beyond this limit, to ensure all contents are copied, including any you just draw a graph.

Start a new project, in the form put a Command and a PictureBox. The PictureBox's Autoredraw property is set to 1. Then add a standard module, copy the following code into the.

Private Type RECT

Left As Long

Top As Long

Right As Long

Bottom As Long

End Type

'GDI function:

Private Declare Function BitBlt Lib "gdi32" (ByVal hDestDC As Long, ByVal x As Long, ByVal y As Long, ByVal nWidth As Long, ByVal nHeight As Long, ByVal hSrcDC As Long, ByVal xSrc As Long, ByVal ySrc As Long, ByVal dwRop As Long) As Long

Private Const SRCCOPY = & HCC0020 '(DWORD) dest = source

'Create a memory DC:

Declare Function CreateCompatibleDC Lib "gdi32" (ByVal hDC As Long) As Long

'In memory to create a bitmap:

Declare Function CreateCompatibleBitmap Lib "gdi32" (ByVal hDC As Long, ByVal nWidth As Long, ByVal nHeight As Long) As Long

'To a GDI object into the DC, back to the original that:

Declare Function SelectObject Lib "gdi32" (ByVal hDC As Long, ByVal hObject As Long) As Long

'Delete the GDI object:

Declare Function DeleteObject Lib "gdi32" (ByVal hObject As Long) As Long

'Clipboard functions:

Private Declare Function OpenClipboard Lib "USER32" (ByVal hWnd As Long) As Long

Private Declare Function CloseClipboard Lib "USER32" () As Long

Private Declare Function SetClipboardData Lib "USER32" (ByVal wFormat As Long, ByVal hMem As Long) As Long

Private Declare Function EmptyClipboard Lib "USER32" () As Long

Private Const CF_BITMAP = 2

Public Function CopyEntirePicture (ByRef objFrom As Object) As Boolean

Dim lhDC As Long

Dim lhBMP As Long

Dim lhBMPOld As Long

'In memory to establish a point we will want to copy the object DC:

lhDC = CreateCompatibleDC (objFrom.hDC)

If (lhDC <> 0) Then

'Create a point will want to copy a bitmap object:

lhBMP = CreateCompatibleBitmap (objFrom.hDC, objFrom.ScaleWidth Screen.TwipsPerPixelX, objFrom.ScaleHeight Screen.TwipsPerPixelY)

If (lhBMP <> 0) Then

'The bitmap selected into the DC we have just set up in and where the old store the original bitmap:

lhBMPOld = SelectObject (lhDC, lhBMP)

'Copy the contents of the objFrom to build a bitmap in:

BitBlt lhDC, 0, 0, objFrom.ScaleWidth Screen.TwipsPerPixelX, objFrom.ScaleHeight Screen.TwipsPerPixelY, objFrom.hDC, 0, 0, SRCCOPY

'Restoration of DC content:

SelectObject lhDC, lhBMPOld

'Now the bitmap into the clipboard:

EmptyClipboard

OpenClipboard 0

SetClipboardData CF_BITMAP, lhBMP

CloseClipboard

'We are here not to delete the establishment of the bitmap -

'It now belongs to the clipboard, when the clipboard changes, Windows will we remove it.

End If

'Clear just created DC:

DeleteObject lhDC

End If

End Function

To test this method, these code to the form:

Private Sub Command1_Click ()

CopyEntirePicture Picture1

End Sub

Private Sub Form_Load ()

Dim i As Long

'Painted in the PictureBox something:

With Picture1.Font

. Name = "Arial"

. Bold = True

. Size = 12

End With

For i = 1 To 20

Picture1.ForeColor = QBColor (i Mod 15)

銆??Picture1.Print &quot;http://www.archtide.com&quot;

Next i

End Sub
