The reason for writing this class is because of the "template class" written by the individual. Because there are many free personal homepage space (because of Ara pole, there is no money to buy space =. =) Does not provide FSO. So causes Scripting.Dictionary Can't be used, so "template class" can't run. So I wrote a thought of "Dictionary Class".
This class does not differ from the use of Scripting.Dictionary object, so it is previously written according to scripting.dictionary, and you can use this class without any modification. This type is more than scripting.dictionary, there is an insert Method: INSERT (SKEY, NKEY, NVAL, NMETHOD), this method is to insert new dictionary data into a dictionary location with SKEY KEY. NKey, NVAL is a key value of new datagical data and value .NMethod is inserted The location. If this value is 1, "B", "Black", or null value, it is inserted into dictionary data with SKEY to Key, otherwise the front.
