Interesting info however at my work I discourage use of report custom code. Generally the logic to turn a textbox red or green is better contained in the underlying SQL which of course is where all the other logic sits. Keeping it all in the one place is easier to write and quicker for other dev's to pick up. For example I'l derive a column named ThresholdExceeded and simply stick a 1 in there for use with a very simple IIF statement against the color proterty in the report. Recently I had to chart the middle value for the month only which could have been the 14th,15th or even the 21st. Far better to T-SQL it rather than just through VB hoops.
