    I have searched the forum but can't find any sample code
    for storing some text into the clipboard. Ideas?

      I found some code somewhere quite a while back and modified it for my needs...

      Function SetClipboardText Alias "SetClipboardText" (ByVal sText As String) Export As Long
        Local hData As Long, hGlob As Long
      ' ** Create a global memory object and copy the data into it
        hData = GlobalAlloc(%GMEM_MOVEABLE Or %GMEM_DDESHARE, Len(sText)+1)
        hGlob = GlobalLock(hData)
        Poke$ hGlob, sText + Chr$(0)
        GlobalUnlock hData
      ' ** Open the clipboard
        If IsFalse(OpenClipboard(%NULL)) Then
          GlobalFree hData
          Exit Function
        End If
      ' ** Paste the data into the clipboard
        Function = SetClipboardData(%CF_TEXT, hData)
      End Function
      Function GetClipboardText Alias "GetClipboardText" () Export As String
       Local zPtr As Asciiz Ptr
       OpenClipBoard 0
       zPtr = GetClipboardData(%CF_TEXT)
       If zPtr <> 0 Then Function = @zPtr
      End Function

        Related subject: Does anyone know how to copy both text and font data
        from a control, like a textbox? MS Charmap does some trick there, using
        plain textbox and when you copy the contents via Copy button, it also
        copies the font.

        Fiddled around with this once, but finally resorted to using Rich Edit
        instead. Would be fun to know how to do it with any control though..

          Borje --
          All is simple - MS products write some formats.
          Try to copy from Word and so on, and look results.

            Yes, once did similar viewer and MS Charmap copy is Rich text format,
            but question is how they do it. Remember I tried many things but never
            got it to work with standard textbox, so to save time, I decided to
            use Rich edit control instead. Have a feeling answer is very simple,
            but hard part is always to find out those simple answers.

            The fun thing with MS Charmap is, if to use right-click menu or Ctrl+C
            to copy from textbox, no font data is stored. Only when using copy button,
            which indicates they render the contents via special function somehow.

            Not important question - don't work with it anymore. Just wondered if
            anyone ever had stumbled upon this and solved the MS Charmap riddle..
