The ProjectItem class in VI Server allows you to inspect and modify items that appear in the Project window, such as VIs, virtual folders, classes, libraries, etc.

If you have a reference to a ProjectItem, you can read the Type String property (short name is TypeString) of the item to identify what kind of item it is:

This is the same string you can use for the Type parameter of the Get All Descendents method of the ProjectItem class to get all children of a ProjectItem that match a specific type:

The following table lists valid Type String values and their descriptions. Update this table with new type strings as you discover them.
