Using Hide When formulas in forms

When LotusScript was introduced in Release 4 of Notes, suddenly many Notes developers began thinking of the Notes formula language as passe. True, it's inadequate for some purposes, such as looping or performing lengthy or complex series of actions. But in many cases it's preferable to LotusScript, for example, when you are working with strings and arrays, computing field values, and populating list boxes. The Hide When formula is used with great frequency. Each element on a form has a Hide When properties tab. These properties dictate when the element (or more accurately, the paragraph in which it resides) is and is not visible. You can use a formula that returns True (nonzero) or False (zero) for this purpose. TIP: Hide When formulas apply to an entire paragraph. You can't select a snippet of text or a graphic within a paragraph and apply a Hide When formula to just the selected item. In some cases, you can work around this limitation by using tables. Each table cell is automatically in a separate paragraph from the cells in the same row. To order the book Advanced Domino 5 Web Programming visit
