How can I change the forecolor of a line

Hi Frank,

You'd need to apply a classification type tag over the line's range and have a highlighting style associated with that classification type.  One way you could do this is to use a custom indicator.  See the "Indicators - Custom" QuickStart for an example.  By altering the HighlightingStyle that is registered for the classification type, you could choose to just change the foreground color.  Also, methods like "editor.Document.IndicatorManager.Add" have overloads where you pass in an ITextSnapshotLine and the indicator will track one particular line.  You can get lines via editor.Document.CurrentSnapshot.Lines[lineno].
