errorcode

An output parameter (return parameter in VB) that contains an error code from 

 in 

If the method was able to set the value it returns true, otherwise it returns false.

If the method was able to set the value it returns VARIANT_TRUE. Otherwise, it returns 
VARIANT_FALSE.

This method returns true if the method succeeds, otherwise false.

The Arguments structure (class) provides key/value support to form a collection of values. Each value 
stored in an Arguments structure is associated with a key. To add an item, use the AddItem or SetValue 
method and pass a key and a value. The key must be a string or an enumerated value, and the value can 
be almost any type (i.e. all types supported by Arg). To retrieve the item, use the appropriate GetValue 
method with a key, and the value is returned. Keys are not case sensitive, and leading and trailing spaces 
are always removed from the key. 

Arguments also supports access by index. The index is useful for retrieving items sequentially, but may 
not be as fast as retrieval by key. The Arguments structure’s index is 1-based, to provide easier support 
for Visual Basic programmers. Internally, the Arguments structure uses a binary tree and other 
techniques to provide fast access to any item. Arguments can support a virtually unlimited number of 
key-value pairs, and supports nested Arguments structure as well.
