DataType  

Description 

(Read/Write) The requested data type that applies to ShowLeafs methods. This property defaults to 

VT_EMPTY, which means that any data type is acceptable. 

Syntax 

DataType As Integer 

Remarks 

Any legal Variant type can be passed as a requested data type. The server responds with names 

that are compatible with this data type (may be none). This property provides the mechanism such 

that the client only gets the leafs that are of a certain DataType.
