A string expression that indicates the HTML format being used to display the
result. The FormatResult property should include %% sequence that's replaced
with the result.
By default, the FormatResult property is "<fgcolor=808080>[=%%]</fgcolor>".
Use the Result property to retrieve the
result. The Text property indicates the
control's expression. Use the IsValid
property to specify whether the expression is syntactically correct and may be
evaluated. The Result is not displayed, if the FormatResult property is empty.
For instance, the format "</r>%%" displays the result in the
right side of the control.
