Use Case

Here we are going to use the continuity of the same example that we used in add to dictionary.
The following activity illustrates on how we can use the set value activity to update the value
for a key in the dictionary. We are going to set the value for the key "John" as "38", and 
view the updated dictionary values with a view activity.

Steps to execute the bot

1.      Drag and drop the set value activity below the view dictionary activity.

2.      Double click on the activity

3.      In the property box give the name of the dictionary as DictNameAge

4.      In the Key, enter the key for which the value must be edited. Here it is John “38”

5.      In the value, enter the new value that must be updated to the specified key. Here
it is John “40”

6.      Select the ArgumentType1 and ArgumentType2 as it is in the dictionary. Here it is
string and Int32 respectively.

7.      Drag and drop the view dictionary activity below the set value activity to view the
updated dictionary.

8.      Execute the workflow to see the updated dictionary.

The bot executes the activity and updates the value in the dictionary which can be seen
using a view activity.
