The ability to create objects from other Office applications is one of the great things about using VBA. For example, you can write a macro that will create an Outlook message object and attach a shortcut to the currently open workbook. A button on the toolbar will perform this same action, which is fine if that’s all you want to do. But using the sample macro below, you can add other text to the message, pre-address it, or perform other actions. You can also tie the creation of the message to some other user action. For instance, you could automatically send a message to certain people if the user saves the workbook and if the values of certain cells match criteria you set—all without any user interaction.

In the early days of the phone system, you picked up a telephone and talked to an operator who put your call through. As more people got phone lines, the phone company began to replace its operators with special switching equipment. When you dialed a number, your telephone sent a signal to the switching equipment, which routed your call to its destination. Such switching systems could handle more calls more efficiently than human operators, but they also opened the door to phone phreaking. Trying to trick a human operator into letting you make a free phone call to Brazil was nearly impossible, but tricking a mindless machine into letting you make free phone calls only required sending signals identical to the phone company’s. If you knew the right signals, the switching systems would blindly obey your orders.

Whether it’s because you have made a call using a mobile phone, received a message on your pager, checked your email from a PDA or even just seen an advert related to it, we have all come across a wireless data or voice network!If a user, application or company wishes to make data portable, mobile and accessible then wireless networking is the answer. A wireless networking system would rid of the downtime you would normally have in a wired network due to cable problems. It would also save time and money due to the fact that you would spare the expense of installing a lot of cables. Also, if a client computer needs to relocate to another part of the office then all you need to do is move the machine with the wireless network card.
