EnableErrorCheck Property

Summary
Gets or sets a value that indicates whether to output the optional check word for validity check when writing a barcode (if supported).
Syntax
C#
Objective-C
C++/CLI
Java
Python
public bool EnableErrorCheck { get; set; } 
@property (nonatomic, assign) BOOL enableErrorCheck; 
public boolean getEnableErrorCheck() 
public void setEnableErrorCheck(boolean value) 
public: 
property bool EnableErrorCheck { 
   bool get(); 
   void set (    bool ); 
} 
EnableErrorCheck # get and set (OneDBarcodeWriteOptions) 

Property Value

true to output the optional check word for validity check when writing a barcode (if supported). Otherwise, false. Default value is false.

Remarks

If you set the value of EnableErrorCheck to true, then the engine will perform error checking (CRC) using the optional check word and the barcode data and output this value along with the barcode data when writing.

The EnableErrorCheck property will only have effect when writing barcode symbologies that support an optional check word. These barcode symbologies are listed below:

The rest of the symbologies supported by this options class requires the check word to be valid and checking is not optional. The engine will always calculate the check word against the data and use it in writing regardless of the value of EnableErrorCheck.
