Hi Dojo,

I have a view with many child DVEs. However, I'm not sure which one is the parent DVE. Is there a way to easily find this information through Cube?

Thanks!

Hi Caio,

You can find the parent element by simply looking at the name. DVEs are named <parent_element_name>.<identifier> like Parent_element.Slot1.

You can also look at the protocol of the DVE. The DVEs take the protocol of the parent element's protocol - so searching in Protocols & Templates also can help you find the parent element.

Hi,
I believe this the default behavior. However, there are some connectors that can implement a different approach. See the option exportProtocol in https://docs.dataminer.services/develop/schemadoc/Protocol/Protocol.Type-options.html
"Add :noElementPrefix to leave out the parent element name in the virtual element name"

Hi Caio,

Another possible way (via Dashboard app) is using a GQI query (see data source 'Get elements'). You could use the column 'DVE Parent ID' to identify the parent element.

Hope it helps.

Hi Caio,

You can send the GetElementByID message via the Client Test Tool. The input IDs should be taken from the DVE element. Example:

Kind regards,

Hi Catarina, thank you for your reply. This is definitely useful! But in cases where I don't have access to Client Test tool, is there an easy way to find this info only using Cube?

you can do the same in an automation script:

IConnection conn = engine.GetUserConnection();

int dataminerID = 1; // change to your dve dma id
int elementID = 123; // change to your dve element id
DMSMessage[] resp = conn.HandleMessage(new GetLiteElementInfo() { DataMinerID = dataminerID, ElementID = elementID });
if (resp.Length == 1 && resp[0] is LiteElementInfoEvent element)
{
// now retrieve the main element via element.DveParentDmaId/element.DveParentElementId
resp = conn.HandleMessage(new GetLiteElementInfo() { DataMinerID = element.DveParentDmaId, ElementID = element.DveParentElementId });
if (resp.Length == 1 && resp[0] is LiteElementInfoEvent mainelement)
{
engine.GenerateInformation("Main element is: " + mainelement.Name);
}
}
