Some message properties have been pre-defined for your convenience. Pre-defined properties can be read but should not be set. The predefined message properties are:
ias_Adapters For network status notification messages, a list of network adapters that can be used to connect to the MobiLink server. The list is a string and is delimited by a vertical bar.
ias_DeliveryCount Int. The number of attempts that have been made so far to deliver the message.
ias_MessageType Int. Indicates the type of the message. The message types can be:
|
Value |
Message type |
Description |
|---|---|---|
|
0 |
REGULAR |
If a message does not have the ias_MessageType property set, it is a regular message. |
|
13 |
PUSH_NOTIFICATION |
When a push notification is received from the server, a message of type PUSH_NOTIFICATION is sent to the system queue. See Notifications of push notification. |
|
14 |
NETWORK_STATUS_NOTIFICATION |
When there is a change in network status, a message of this type is sent to the system queue. See Network status notifications. |
ias_RASNames String. For network status notification messages, a list of RAS entry names that can be used to connect to the MobiLink server. The list is delimited by a vertical bar.
ias_NetworkStatus Int. For network status notification messages, the state of the network connection. The value is 1 if connected, 0 otherwise.
ias_Originator String. The message store ID of the originator of the message.
ias_Status Int. The current status of the message. This property is not supported in the SQL API. The values can be:
| Status Code | Description |
|---|---|
| 1 | Pending - The message has been sent but not received. |
| 10 | Receiving - The message is in the process of being received, or it was received but not acknowledged. |
| 20 | Final - The message has achieved a final state. |
| 30 | Expired - The message was not received before its expiration time has passed. |
| 40 | Cancelled - The message has been canceled. |
| 50 | Unreceivable - The message is either malformed, or there were too many failed attempts to deliver it. |
| 60 | Received - The message has been received and acknowledged. |
There are constants for the status values. See:
ias_StatusTime The time at which the message became its current status. It is in units that are natural for the platform. It is a local time. In the C++ API, for Windows and PocketPC platforms, the timestamp is the SYSTEMTIME, converted to a FILETIME, which is copied to a qa_long value. This property is not supported in the SQL API.
| API | This property returns... |
|---|---|
| .NET | DateTime |
| C++ | string |
| Java | java.util.Date object |
The QAnywhere APIs for .NET, C++, and Java provide constants for specifying message properties. See:
