Search for: KB10405 - Using XDK to build a custom layer. Question from a customer: ''Can I use ActiveX DK objects, methods, and properties in my application to take data from a proprietary data structure and build a layer which the DK can then work with as if the layer had originally been loaded from one of the DK-supported data sources?'' Answer: Generally, yes. All the layers are treated exactly the same way. Created: November 21, 2003, Modified: August 05, 2015
