Data type

Double

Syntax

ObjectName. CapItems(long index)

Remarks

Reading this property after calling CapGet() method. After setting this property, call CapSet() method to actually set the value.

This property has a parameter. The data type of the parameter is Long and it is 0-based.

The Double type of CapItems property is used to present Double, Single(Float), Long, Integer and even Boolean types. For String type, please use CapItemsString property.

When using Double type for Boolean type, 1 denotes TRUE, 0 denotes FALSE. The constant True/False of Visual Basic can NOT be used.

This is very like CapValue property and CapValueString property, where CapValueString property is used to present String type and CapValue is used to present other types. CapValue property and CapValueString property are used when the container type is TWON_ONEVALUE.

When an error occurs and IfThrowException property is TRUE, an exception will be thrown. Check ErrorCode property and ErrorString property for error information.
