Abstract: A method, system, and apparatus for providing access to asynchronous data in a spreadsheet application program is provided. When a request is received to utilize an asynchronous data element in a spreadsheet, the spreadsheet application program instructs an asynchronous data server to provide updated values for the asynchronous data element. When the asynchronous data server program receives an updated value, it notifies the spreadsheet application program that a changed value for the data element is available. The next time the spreadsheet application program has idle processing time following a notification that an update is available, the spreadsheet application program determines whether a notification has been received from the asynchronous data server program. If an update is available, the spreadsheet application program contacts the asynchronous data server and requests the update. In response, the asynchronous data server program transmits the update to the spreadsheet application program.

Abstract: A system and methods for joining the correct wireless network are provided. The invention allows a device connecting to an unsecure wireless network to choose the correct network from many available wireless networks which are in range. A piece of code is executed on one of the PCs already on the network, then the device connects to each unsecure wireless network in range and sends a small message. If that message receives a reply from the code running on the PC that is already on the wireless network, that particular wireless network is determined to be the correct wireless network.
