Microsoft Access does not have a command that sends information to the
Clipboard. To post information to the Clipboard, you need to define a
Visual Basic for Applications function that calls several Microsoft Windows API functions. This article shows you how to create a function that copies text to the Clipboard.
To copy information to the Clipboard, follow these steps:
NOTE: You may have some Microsoft Windows API functions defined in an existing Microsoft Access library; therefore, your declarations may be
duplicates. If you receive a duplicate procedure name error message, remove
or comment out the declarations statement in your code.
Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements.
- Start Microsoft Access and open any database or project.
- Create a module and type or paste the following lines in the Declarations section:
Declare Function GlobalUnlock Lib "kernel32" (ByVal hMem As Long) _
Declare Function GlobalLock Lib "kernel32" (ByVal hMem As Long) _
Declare Function GlobalAlloc Lib "kernel32" (ByVal wFlags As Long, _
ByVal dwBytes As Long) As Long
Declare Function CloseClipboard Lib "User32" () As Long
Declare Function OpenClipboard Lib "User32" (ByVal hwnd As Long) _
Declare Function EmptyClipboard Lib "User32" () As Long
Declare Function lstrcpy Lib "kernel32" (ByVal lpString1 As Any, _
ByVal lpString2 As Any) As Long
Declare Function SetClipboardData Lib "User32" (ByVal wFormat _
As Long, ByVal hMem As Long) As Long
Public Const GHND = &H42
Public Const CF_TEXT = 1
Public Const MAXSIZE = 4096
- Type or paste the following procedure:
Function ClipBoard_SetData(MyString As String)
Dim hGlobalMemory As Long, lpGlobalMemory As Long
Dim hClipMemory As Long, X As Long
' Allocate moveable global memory.
hGlobalMemory = GlobalAlloc(GHND, Len(MyString) + 1)
' Lock the block to get a far pointer
' to this memory.
lpGlobalMemory = GlobalLock(hGlobalMemory)
' Copy the string to this global memory.
lpGlobalMemory = lstrcpy(lpGlobalMemory, MyString)
' Unlock the memory.
If GlobalUnlock(hGlobalMemory) <> 0 Then
MsgBox "Could not unlock memory location. Copy aborted."
' Open the Clipboard to copy data to.
If OpenClipboard(0&) = 0 Then
MsgBox "Could not open the Clipboard. Copy aborted."
' Clear the Clipboard.
X = EmptyClipboard()
' Copy the data to the Clipboard.
hClipMemory = SetClipboardData(CF_TEXT, hGlobalMemory)
If CloseClipboard() = 0 Then
MsgBox "Could not close Clipboard."
- To test this function, type the following line in the Immediate window, and then press ENTER.
? ClipBoard_SetData("To Clipboard")
Press CTRL+V (the shortcut for Paste) and note that "To Clipboard" is pasted into the Immediate window from the Clipboard.
