Clarification on Wikia article, showing how to add a userform.

[Matt_Double_You]

Hi there,

Could someone please clarify the process for communicating between a userform and TestCSharpDll.cs?  I'm learning C#, and have created a little plugin that updates CustomTags each time a new track plays.  I'm now wanting to let the user choose which CustomTags will be updated.  Unfortunately, I can't figure out how to populate the userform comboboxes (or even a single messagebox) with the field names of the custom tags.  I've provided the code for the userform below, but I suspect I'm well on the wrong track.

namespace MusicBeePlugin
{
  public partial class ConfigSettings : Form
  {
      public ConfigSettings()
      {
          InitializeComponent();
      }
      public ConfigSettings(Plugin.MusicBeeApiInterface pApi)
      {
      }
      private Plugin.MusicBeeApiInterface mApi;
      private void ConfigSettings_Load(object sender, EventArgs e)
      {
        MessageBox.Show(mApi.Setting_GetFieldName(Plugin.MetaDataType.Custom1));
      }
  }
}
