All About Dictionary Object in QTP/UFT

There are many ways to use Dictionary Objects but the most common use of Dictionary Object is to keep the value in an Array and refer each value with a unique Key or Index. Basically, Dictionary Object is nothing but an Array which contains values which are referred by unique keys. For each value in Dictionary Object, there is one unique key associated with value. Using Key name, we can call associated value anywhere in the script.
