Add various colored text and other formatting to forms and reports in your database, depending upon which conditions are met, even without the conditional formatting feature provided by Microsoft Access 2000 and later versions.
Microsoft Access 2000 and later versions provide conditional formatting for text boxes and combo boxes that allow you to change the display of the text from the regular settings applied in the Properties window, depending upon whether certain conditions you have identified have been met. This may be colored text, highlighted text, or bold, italic or underlined text. Conditional formatting can even allow you to enable or disable the text box or combo box control. However, this feature isn't available in earlier versions, and there are a few limitations in the built-in conditional formatting, as we'll soon find out.
