The RemoveItem method removes a value and its associated key from an 
arguments array. Subsequent attempts to access a value that was removed using 
RemoveItem will fail.

bool RemoveItem( std::string& key );

bool RemoveItem( char * key );

bool RemoveItem( enum_Keywords key );

HRESULT RemoveItem(/*[in]*/ VARIANT* key, /*[out, retval]*/ 

VARIANT_BOOL* bSuccess);

RemoveItem ( key as Variant) as Boolean

boolean RemoveItem(int key)

boolean RemoveItem(String key)

key

The key to use to locate and remove the item in the Arguments array. Leading 
and trailing spaces are always removed from the key.

A True return value means the entry was located and removed.

The SetElement method is identical to SetValue (which is similar to AddItem), 
except that it uses an index value instead of a key. 

bool SetElement( int index, int value );

bool SetElement( int index, unsigned int value );

bool SetElement( int index, unsigned short value );

bool SetElement( int index, short value );
