The following code snippets show how to create and change this object in your code. These examples assume that you have placed a control named audioDjStudio1 on a form or dialog and that you want to change a couple of graphic settings (Bands and Background colors).

Visual Basic.NET

Here follows the code needed to perform the requested operations

' create the spectrum on player 0 over an existing control

AudioDjStudio1.DisplaySpectrum.Create(0, PictureBox1.Handle)

' set the blue color for spectrum bands of player 0

AudioDjStudio1.DisplaySpectrum.set_ColorBands(0, Color.Blue)

' set the white color for spectrum background of player 0

AudioDjStudio1.DisplaySpectrum.set_ColorBackground(0, Color.White)

Visual C#.NET

Here follows the code needed to perform the requested operations

// create the spectrum on player 0 over an existing control

audioDjStudio1.DisplaySpectrum.Create(0, pictureBox1.Handle);

// set the blue color for spectrum bands of player 0

audioDjStudio1.DisplaySpectrum.set_ColorBands (0, Color.Blue);
