Control style bit flags are used to categorize supported behavior. A control can enable a style by calling the SetStyle method and passing in the appropriate ControlStyles bit and the Boolean value to set the bit to. To determine the value assigned to a specified ControlStyles bit, use the GetStyle method and pass in the ControlStyles member to evaluate.

The following code example returns the value of the double-buffering related style bits for a Form. This example returns true only if all the style bits are set to true.

Public Function DoubleBufferingEnabled() As Boolean
   ' Get the value of the double-buffering style bits.
   Return Me.GetStyle((ControlStyles.DoubleBuffer _
     Or ControlStyles.UserPaint _
     Or ControlStyles.AllPaintingInWmPaint))
End Function

public bool DoubleBufferingEnabled()
{
   // Get the value of the double-buffering style bits.
   return this.GetStyle(ControlStyles.DoubleBuffer | 
      ControlStyles.UserPaint | 
      ControlStyles.AllPaintingInWmPaint);
}

public:
   bool DoubleBufferingEnabled()
   {

      // Get the value of the double-buffering style bits.
      return this->GetStyle( static_cast<ControlStyles>(ControlStyles::DoubleBuffer | ControlStyles::UserPaint | ControlStyles::AllPaintingInWmPaint) );
   }
