Learning VBA
After installing Visual Studio Tools for Office and exploring it's functionalities, we've come to the conclusion that we won't be needing it. The current requirement is just to present the data to the client in a number of ways which is currently using Excel macros. Deployment is a big factor for this decision since deployment of VSTO projects would need the runtime installed with the accompanying assembly to the workbook, definitely additional overhead for clients who were used to just transfer the Excel workbook.
Currently, I'm reading this Excel 2003 programming book before i delve into the old code of the macros. I view this as a good experience (really?), i might make use of this VBA in the future.
