Item - property of object PmTrend
The property enables an access to the object of Var
type that represents one variable defined on the page Data
. The variable is there defined by the index
Item(index As Variant) As Object
Writing the value:
oTrend.Item(index).Value = val
|index||(Variant) Identification of the variable either by its name (String data type, case sensitive text, for example "a1") or by the index (zero-based index).|
Property access for read only
The Var object includes information about the variable (value, name, index, etc.).
The Item property (like Var object) is read only, it means that the object cannot be changed but for example it is possible to write into the Value of the Var object.
If the variable doesn't exist, then Nothing value is returned. global error in the INFO system is generated. For variable existence testing, it is better to use the ItemEx property.
