Hi,

I suppose you meant " How to programmatically add topic to Discussion Board, and some comments to topic..." ? Below is the sample code that you can modify and create a Discussion topic and then discussion message entity.

Create a DiscussionTopicEntity

Few notes:
1. You need to get the BoardId where you want to create a Topic
2. Pass in the id of the Topic as an Guid to get the proper PK
3. UserId parameter specifies the owner / creator of the Topic - you can use SecurityUtility.GetUserId() if you want to pass in the current user id

Create a DiscussionMessageEntity (Post)

Few notes:
1. You need to get the TopicId of the previously created topic you can do that by using the topic entity property Id
2. Pass in the id of the Message as an Guid to get the proper PK
3. UserId parameter specifies the owner / creator of the Message - you can use SecurityUtility.GetUserId() if you want to pass in the current user id

If you want to implement AntiXSS or SPAM security while posting a message you can use the following code

To implement AntiXSS security on the message html content use
To implement AntiXSS security on the message plain text content use

To implement SPAM check you can use the following

I hope I have covered everything you need, let us know if you need anything else.
