First, you need to create your List :

Code:

SPWeb web = //[Get your web]
SPList MyList = Utilities.CreateList(web, Title, Key, SPListTemplateType.GenericList);

Then you do the following to create the SPFieldMultiLineText

Code:

// Add RichText column
string htmlFieldName = Utilities.AddField(MyList, SPFieldType.Note, FieldName, false, true);
SPFieldMultiLineText htmlField = MyList.Fields[FieldName] as SPFieldMultiLineText;
htmlField.RichText = true;
htmlField.RichTextMode = SPRichTextMode.FullHtml;
htmlField.Update();

You can even rename the original Title column

Code:

// Rename the original Title column
SPField TitleField = MyList.Fields[SPBuiltInFieldId.Title];
TitleField.Title = anOtherName;

Finally, we run our code snippet into an event receiver

Code:

[Guid("xxx")]
public class MybEventReceiver : SPFeatureReceiver
 {
 public override void FeatureActivated(SPFeatureReceiverProperties properties)
  {
  SPWeb web = //[Get your web]
  SPList MyList = Utilities.CreateList(web, Title, Key, SPListTemplateType.GenericList);
  // Rename the original Title column
  SPField TitleField = MyList.Fields[SPBuiltInFieldId.Title];
  TitleField.Title = anOtherName;
  // Add RichText column
  string htmlFieldName = Utilities.AddField(MyList, SPFieldType.Note, FieldName, false, true);
  SPFieldMultiLineText htmlField = MyList.Fields[FieldName] as SPFieldMultiLineText;
  htmlField.RichText = true;
  htmlField.RichTextMode = SPRichTextMode.FullHtml;
  htmlField.Update();
  }
 }

Actually, this could run for SharePoint 2010 too. 

Are you having a similar name for your adminCentral database : SharePoint_AdminContent_[GUID] ?
If you are looking for more control, this is how you can create databases with "better" names :

1. Launch the SharePoint 2013 Management PowerShell as an Administrator.
2. Type this :
   
   Code:
   

   New-SPConfigurationDatabase -DatabaseName CONFIG_DB_NAME_HERE -DatabaseServer SERVER_NAME_HERE -AdministrationContentDatabaseName ADMIN_DB_NAME_HERE -FarmCredentials (Get-Credential) -Passphrase (ConvertTo-SecureString "TYPE_YOUR_PWD_HERE" -AsPlainText -Force)
   

Notice that you can use this command, only before executing the SharePoint 2013 configuration Wizard, so just after binaries been installed.
During the installation, you'll be asked to launch the wizard and continue the process. You'll have to uncheck the checkbox.

Today, I'd to speek about giving users the possibility to like SharePoint 2013 posts using the Client Object API.
You'll need to instanciate your SocialFeedManager with your context, and then call the "LikePost" method with the postId you would 'like'.

Code:

public SocialThread LikeThisPost(string SharePointWebUrl, string PostId)
 { 
 SocialFeedManager feedManager = new SocialFeedManager(ctx);
 ClientResult thread = feedManager.LikePost(PostId);
 ctx.ExecuteQuery();
 return thread.Value;
 }

This method returns the whole thread, containing the root post, all the replies and many other attributes.
Maybe you'll need to parse this result into your business post object.

From the SocialPost's LikerInfo collection you could know if the current user likes the post or not.
No need to try to implement some logic for getting this, SharePoint has already done this for you.

Code:

bool CurrentUserLikesThis = socialPost.LikerInfo.IncludesCurrentUser;

Hi everybody,
