2. ADXRTLIST
2.1. ADXRTLIST PROPERTIES
2.1.1. Source
Source
Name of the data source as a string.
Arguments
None
Error Handling
Depends on the value of the DebugLevel general property, as follows:
RT_DEBUG_NO
If the source is already known as invalid or down, an exception is raised. If the status of the
source is unknown, then the process continues without any warning or error.
RT_DEBUG_IMMEDIATE
When using SSL, the source is checked for validity. If it is not valid an exception is raised
before setting a new property value.
If the source is unknown or down an exception is raised.
It is important to note that in this mode the setting of the Source property could be very slow.
Example
Public list as AdxRtList
Set list = New AdxRtList
'Declare as global variable'
'Create an instance of the list object. This syntax is more
efficient than when only the new instruction is used. Otherwise,
before execution, Visual Basic will test each statement
containing list for the value Nothing. '
list.Source = "IDN_SELECTFEED"
'Set the source name to "IDN_SELECTFEED"'
2.1.2. Mode
Mode
This property describes various behavioural aspects of the AdxRtList object. In particular, it
determines how the list object will deliver data update events to the client application. The allowed
parameters are:
FRQ : The frequency of regularly generated events. If the list’s StartUpdates
method was called with the run mode value RT_MODE_ONTIME or
RT_MODE_ONTIME_IF_UPDATED, OnTime events will be triggered at this
frequency. The minimum frequency is one event per second.
FRQ:iH set a frequency of one event every i hours.
FRQ:iM set a frequency of one event every i minutes.
FRQ:iS set a frequency of one event every i seconds.
The default frequency is one event every 10 seconds.
