If RView contains an invalid value, an error exception will be thrown.
Example
Public list as AdxRtList
Set list = New AdxRtList
Dim MyArray as Variant
MyArray = list.ListFields("DEM=", RT_FRV_ALL, RT_FCV_VALUE)
NumFields = list.FieldListCount("DEM=", RT_FRV_ALL)
'NumFields holds the number of rows (fields) contained in
MyArray. '
2.1.12. ItemListCount
ItemListCount(RView)
This property supplies the number of items described by the ListItems property.
Arguments
RView
One of the values from the RT_ItemRowView enumeration. This specifies
how the counting should be performed: one row for each updated field, one
row for each registered field, or one row for each field supplied by the
identified item.
Return Value
The number of items counted is supplied as an integer. This will be zero if an error occurs.
Error Handling
An error exception may be thrown in the following cases:
If RView is set to RT_IRV_UPDATED and the property is queried outside of an event callback (i.e.
one of OnImage, OnUpdate or OnTime), the return value will be 0. In this case, an error exception
will be thrown.
If RView contains an invalid value, an error exception will be thrown.
Example
Public list as AdxRtList
Set list = New AdxRtList
Dim MyArray as Variant
MyArray = list.ListItems(RT_IRV_ALL, RT_ICV_USERTAG)
ListCount = list.ItemListCount(RT_IRV_ALL)
'ListCount holds the number of rows (items) contained in
MyArray. '
