DoubleBuffer Property

Summary

Gets or sets a flag that indicates whether to enable double buffering.

Syntax

C++

public bool DoubleBuffer { get; set; }

  
Public Property DoubleBuffer As Boolean

public: 
property bool DoubleBuffer { 
   bool get(); 
   void set (    bool ); 
}

Property Value

Flag that indicates whether to use double buffering while doing memory transfer. Possible values are: true to enable double buffering, false to not enable double buffering.

Remarks

When true, the buffer specified with MemoryBufferSize will be multiplied by 2 internally. If MemoryBufferSize is 0 then the default buffer size (64K) will be used internally and then it will be doubled. When false, no double buffering is used. This is the default value.
