Const GMEM_ZEROINIT = &H2
Const CF_TEXT = &H01


Declare Function OpenClipboard Lib "user32" Alias "OpenClipboard" (Byval hwnd
As Long) As Long

Sub SetClipboardText(text As String)

Dim hwnd As Long
Dim hGlobalMemory As Long
Dim lpGlobalMemory As Long
Dim ret As Long

On Error Goto error_handler

' Get a handle to current window

If hwnd Then
' Allocate memory

Clng(Len(text)+1))

If hGlobalMemory Then

lpGlobalMemory = GlobalLock(hGlobalMemory)

If lpGlobalMemory Then

ret = lstrcpy(lpGlobalMemory, text)

Call GlobalUnlock(hGlobalMemory)

If OpenClipboard(hwnd) Then
