Hi,

Assembly.GetExecutingAssembly().GetType(
"[YOUR PROJECT NAME]." & objectName)
The above line searches in the assembly manifest for the type specfied by objectName and returns that type.

returnObj = Activator.CreateInstance(Type, args

Teh above line calls the constructor of the specfied type by passing the arugments if required for the type and returns an instance of the type.

The above code is using Reflection to dynamically create a type based on the given object name. Using reflection, given a type it creates an instance object. The above code extracts the type information from the assembly metadata and then creates and instance of the object/
