Copy Contents of Listbox to Clipboard

How can I copy all the contents of a listbox to a clipboard?

I have tried loopping though all the contents of the listbox then using the

VB Code:

DoCmd.RunCommand acCmdCopy

But doesn't seem to copy everything.

what are you working in.. Access?
that command will only copy one line...

you need to put all the lines in a variable and set that to the clipboard:

VB Code:

Private Declare Function GlobalUnlock Lib "kernel32" (ByVal hMem As Long) As Long
Private Declare Function GlobalLock Lib "kernel32" (ByVal hMem As Long) As Long
Private Declare Function GlobalAlloc Lib "kernel32" (ByVal wFlags As Long, ByVal dwBytes As Long) As Long
Private Declare Function CloseClipboard Lib "User32" () As Long
Private Declare Function OpenClipboard Lib "User32" (ByVal hwnd As Long) As Long
Private Declare Function EmptyClipboard Lib "User32" () As Long
Private Declare Function lstrcpy Lib "kernel32" (ByVal lpString1 As Any, ByVal lpString2 As Any) As Long
Private Declare Function SetClipboardData Lib "User32" (ByVal wFormat As Long, ByVal hMem As Long) As Long
Private Const GHND = &H42
Private Const CF_TEXT = 1
Private Const MAXSIZE = 4096
 
Public Function ClipBoard_SetData(MyString As String)
    Dim hGlobalMemory As Long, lpGlobalMemory As Long
    Dim hClipMemory As Long, X As Long
    
    hGlobalMemory = GlobalAlloc(GHND, Len(MyString) + 1)
    lpGlobalMemory = GlobalLock(hGlobalMemory)
    
    lpGlobalMemory = lstrcpy(lpGlobalMemory, MyString)
    If GlobalUnlock(hGlobalMemory) <> 0 Then
        MsgBox "Could not unlock memory location. Copy aborted."
        GoTo OutOfHere2
    End If
    If OpenClipboard(0&) = 0 Then
        MsgBox "Could not open the Clipboard. Copy aborted."
        Exit Function
    End If
    .
    X = EmptyClipboard()
    hClipMemory = SetClipboardData(CF_TEXT, hGlobalMemory)
    
OutOfHere2:
    
    If CloseClipboard() = 0 Then
        MsgBox "Could not close Clipboard."
    End If
 
End Function
 
Private Sub Command2_Click()
    Dim tmp As String
    For X = 0 To List3.ListCount
        List3.Selected(X) = -1
        tmp = tmp & List3.ItemData(X) & vbCrLf
    Next
    ClipBoard_SetData tmp
End Sub
