Namespace: Microsoft.PointOfService
Assembly: Microsoft.PointOfService (in microsoft.pointofservice.dll)

Syntax

'Declaration
Public MustOverride Sub FreezeValue ( _
    item As Integer, _
    freeze As Boolean _
)

public abstract void FreezeValue (
    int item,
    bool freeze
)

public:
virtual void FreezeValue (
    int item, 
    bool freeze
) abstract

public abstract void FreezeValue (
    int item, 
    boolean freeze
)

public abstract function FreezeValue (
    item : int, 
    freeze : boolean
)

Parameters

  • item
    The bitwise value of FreezeValueType flags that sets the state of the selected parameter item or items.
  • freeze
    If true, the item is not automatically set to zero when the item is removed from the scale.

Remarks

This method performs a bitwise logical OR function to determine the state of the item or items selected after a ReadWeight or a DoPriceCalculating method is called. If the item bit value is true, then the scale does not clear (set to zero) the associated tare values and/or unit price. If item bit value is false, then the scale will clear (set to zero) the associated tare values and/or unit price.

This method may cause a PosControlException to be thrown with the following error codes:

Value

Meaning

E_ILLEGAL

The current state of the scale device does not allow the freezing of the requested tare or unit price value.
