I\'m creating a dictionary system, where words meaning is editable in RichTextBox
(for user define FontSize, Color, etc...)
So how to can I save meaning
You can just use the "Memo" field type if you're in Access 2007 or newer. Setting the TextFormat property to RichText will allow for RTF.
To edit it, just use a text box with the appropriate field set as its control source.
To read it via code, access the .Value property. You can also insert formatting tags (e.g. ) this way if you'd like.
