GetClipText retreives the current text in the clipboard.

SetClipText sets the required text to the clipboard.

function GetClipText(var szText:string):Boolean;
var
  hData:  DWORD;
  pData:  Pointer;
  dwSize: DWORD;
begin
  Result := FALSE;
  if OpenClipBoard(0) then
  begin
    hData := GetClipBoardData(CF_TEXT);
    if hData <> 0 then
    begin
      pData := GlobalLock(hData);
      if pData <> nil then
      begin
        dwSize := GlobalSize(hData);
        if dwSize <> 0 then
        begin
          SetLength(szText, dwSize);
          CopyMemory(@szText[1], pData, dwSize);
          Result := TRUE;
        end;
        GlobalUnlock(DWORD(pData));
      end;
    end;
    CloseClipBoard;
  end;
end;
function SetClipText(szText:string):Boolean;
var
  pData:  DWORD;
  dwSize: DWORD;
begin
  Result := FALSE;
  if OpenClipBoard(0) then
  begin
    dwSize := Length(szText) + 1;
    if dwSize <> 0 then
    begin
      pData := GlobalAlloc(MEM_COMMIT, dwSize);
      if pData <> 0 then
      begin
        CopyMemory(Pointer(pData), PChar(szText), dwSize);
        if SetClipBoardData(CF_TEXT, pData) <> 0 then
          Result := TRUE;
      end;
    end;
    CloseClipBoard;
  end;
end;

Usage:

var
  szText: string;
begin
  if SetClipText('Hello World!') then
  begin
    if GetClipText(szText) then
      MessageBox(0, PChar(szText), nil, 0);
  end;
end.
