This section aims at providing some explanations about some workarounds used in code in order to provide flexibility.

·         To provide the ability to concatenate strings, such as in the employee name, char(43) was used and replaced by a "+" when receiving the query string to prevent IE from replacing it by a space.

·         Another tip is the java function that trims the text box content before it is sent to the combo filter to allow for maximum search capability.

·         Another Tip is using the Char(32) to provide the space option when concatenating.

·         This allows the user to fill the combo box only when needed, not with the original page in order to minimize the page size.
