Excel 2003 - How to build my own XLA?

How can you make the .xla file if you want to create your own xla? I have the code, classes, shapes, etc....what is the process to makin开发者_运维技巧g an xla file to point to? I know that I have to put it in my program files folder, and then go through the steps to adding an "add-in" in xls...but i mean actually saving an xla file to point to....

can i simply write all this in xls and then save it as file type xla?? because i have tried to do that but I get an error that it is not a valid add in when I am in a spreadsheet trying to point to it?

thanks!
