Advanced: Requires expert coding, interoperability, and multiuser skills.

This article applies to a Microsoft Access database (.mdb) and to a Microsoft Access project (.adp).



SUMMARY
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.



MORE INFORMATION
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) _ As Long Declare Function GlobalLock Lib "kernel32" (ByVal hMem As Long) _ 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) _ 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." GoTo OutOfHere2 End If

' Open the Clipboard to copy data to. If OpenClipboard(0&) = 0 Then MsgBox "Could not open the Clipboard. Copy aborted." Exit Function End If

' Clear the Clipboard. X = EmptyClipboard

' Copy the data to the Clipboard. hClipMemory = SetClipboardData(CF_TEXT, hGlobalMemory)

OutOfHere2:

If CloseClipboard = 0 Then MsgBox "Could not close Clipboard." End If

End Function

 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.
