Custom Dialogs

Bot Framework v4 custom dialogs bot sample

This bot has been created using Bot Framework, it shows how to sub-class the Dialog class to create different bot control mechanism like simple slot filling.

BotFramework provides a built-in base class called Dialog. By subclassing Dialog, developers can create new ways to define and control dialog flows used by the bot.

Running the sample

  • Clone the repository
git clone https://github.com/Microsoft/botbuilder-samples.git
  • Bring up a terminal, navigate to botbuilder-samples\samples\python\19.custom-dialogs folder
  • Activate your desired virtual environment
  • In the terminal, type pip install -r requirements.txt
  • Run your bot with python app.py

Testing the bot using Bot Framework Emulator

Microsoft Bot Framework Emulator is a desktop application that allows bot developers to test and debug their bots on localhost or running remotely through a tunnel.

  • Install the Bot Framework emulator from here

Custom Dialogs

BotFramework provides a built-in base class called Dialog. By subclassing Dialog, developers can create new ways to define and control dialog flows used by the bot. By adhering to the features of this class, developers will create custom dialogs that can be used side-by-side with other dialog types, as well as built-in or custom prompts.

This example demonstrates a custom Dialog class called SlotFillingDialog, which takes a series of "slots" which define a value the bot needs to collect from the user, as well as the prompt it should use. The bot will iterate through all of the slots until they are all full, at which point the dialog completes.

Deploy the bot to Azure
