Hola amigos!!!
Necesito imprimir un TreeView.
En la web encontre este codigo de dephi, pero no lo puedo traducir a Builder c++, no se que significa WM_PRINT, etc..
A ver si alguine me da una mano

var
 bmp: TBitmap;
begin
 bmp := TBitmap.Create;
 try
   bmp.Width := TreeView1.Width;
   bmp.Height := TreeView1.Height;
   bmp.Canvas.Lock;
   try
     TreeView1.Perform(WM_PRINT, bmp.Canvas.Handle, PRF_CHILDREN or
PRF_CLIENT or PRF_NONCLIENT);
   finally
     bmp.Canvas.UnLock;
     bmp.SaveToFile('d: ree.bmp')
   end;
 finally
   bmp.Free
 end;
end;

Graphics::TBitmap *bmp = new Graphics::TBitmap;
 bmp->Width = TreeView1->Width;
  bmp->Height = TreeView1->Height;
  bmp->Canvas->Lock();
   TreeView1->Perform(100, (int ) bmp->Canvas->Handle, 100);
     bmp->Canvas->Unlock();
