For some reason you cannot inherit from ProgressBar and implement this.

But you can add a handler for ProgressBar.Invalidated event and use some code like:-

      StringFormat sf = StringFormat.GenericDefault ;
      sf.Alignment = StringAlignment.Center ;
      sf.LineAlignment = StringAlignment.Center ;

      Graphics g = progressBar1.CreateGraphics();
      g.DrawString( "Transparancy" , Font , SystemBrushes.WindowText , progressBar1.Width / 2  , progressBar1.Height / 2  , sf );
      g.Dispose();

I couldn't make it work either so I too placed it whenever I changed the Progress Bar. Sadly though this simply didn't work or look anything like working.

        Dim sf As StringFormat  = StringFormat.GenericDefault
       
        sf.Alignment = StringAlignment.Center
        sf.LineAlignment = StringAlignment.Center

        Dim g As Graphics = pbStorageUsed.CreateGraphics()
        g.DrawString( labFreeSpace.Text , Font , SystemBrushes.WindowText , CInt(pbStorageUsed.Width / 2)  , CInt(pbStorageUsed.Height / 2)  , sf )
        g.Dispose()

Does the author have an explanation for absolutely nothing appearing?  (Yes, there is text in labFreeSpace.Text).
