In fact, that's much of what Excel 2003 is all about--solving problems that deal with teamwork-- collecting and sharing data, programming across applications, and maintaining security.The latest in our Developer's Notebook series, this guide introduces intermediate to advanced Excel VBA programmers to the newest programming features of Excel 2003,--focusing just on what's new--so you can get up to speed quickly.
