MsiProcessMessage has full documentation on record fields. Generally, you define a template for ActionData messages with ProgressText element.

<ProgressText Action="MyAction" Template="My name is [1]"/>

Then, in the custom action code, you send records with the template parameters.

using (Record rec = new Record(2))
  rec[1]= "Oscar Acosta";
  session.Message(InstallMessage.ActionData, rec);
