L_BOOL LBarCode::IsValid (L_VOID)

Determines whether the LBarCode object is valid.



There is a pointer to a valid bitmap object.


There is not a pointer to a valid bitmap object.


Call this function to determine whether the class object has been associated with a valid LBitmapBase object.

Before using some of the LBarCode functions, a bitmap must be associated with the class object. Until a valid bitmap object is associated with the LBarCode object, this function will return false.

Specifically, barcodes cannot be read or written until a valid bitmap is associated with the LBarCode class object.
