How can I get a layer's DataSource properties. I have some loaded layers in a map control, and I would like to get some information from these layers.Do you know what classes/interfaces I need to use in order to get theinformation that is displayed in a layer properties Source tab. (Seeattached pic)
Keep in mind, these are ALREADY loaded layers. I'm not attempting norable to load the layers myself and get the information at that point.(if that makes any difference)
I'm looking for the data for these items
- Data Type:
- Feature Class:
- SERVER:
- INSTANCE:
- Location:
- AUTHENTICATION_MODE:
- VERSION:
- Feature Type
- Geometry Type

Re: How can I get a layer's DataSource properties. Just for reference, may be wrong
•Data Type: IFeatureLayer.DataSourceType
•Feature Class: IFeatureLayer.featureClass
•SERVER: IFeatureLayer.featureClass->Idataset->IpropertySet->GetProperty("Server")
•INSTANCE:IFeatureLayer.featureClass->Idataset->IpropertySet->GetProperty("Instance")
•Location:IFeatureLayer.featureClass->Idataset->IpropertySet->GetProperty("database")
•AUTHENTICATION_MODE:IFeatureLayer.featureClass->Idataset->IpropertySet->GetProperty("AUTHENTICATION_MODE")
•VERSION:IFeatureLayer.featureClass->Idataset->IpropertySet->GetProperty("version")

0 Re: How can I get a layer's DataSource properties. have you got a sample of this working? I'm trying to do exactly thesame thing with some SDE layers in a map but hitting an error.
pfeatureclass = pfeaturelayer.FeatureClass
pdataset = pfeatureclass.FeatureDataset
MsgBox(pdataset.PropertySet.GetProperty("Server"))
pfeatureclass seems to be set okay but pdataset is always nothing which then causes the propertyset to fail Reply With QuoteTopBottom

0 Re: How can I get a layer's DataSource properties. You can use pfeatureclass.FeatureDataset if the feature class is storedinside feature dataset. if not use below statement to convertifeatureclass to idataset and then get the connection properties.
IDataset pdataset = pfeatureclass as IDataset; Reply With QuoteTopBottom

0 Re: How can I get a layer's DataSource properties. Well, another option, if the data is published via server, would be to use:
.NET
IPublishLayer.DataDetails
http://help.arcgis.com/en/sdk/10.0/a...0p29000000.htm
Java
FeatureLayer.getDataDetails()
http://help.arcgis.com/en/sdk/10.0/j...tureLayer.html
You get a nicely formatted String with those properties you're looking for.
Data Type: ArcSDE Database
Location: Server: Server Name
User: username
Instance: sde:sqlserver:whatever
Version: dbo.DEFAULT
Description: Instance default version.
Feature Class: server.owner.name
And, as you can see the Java version gets the output wrong. I reported as a potential bug...
