Hello, Is WriteExcel backwards compactible? meaning can the new version operate old code that was meant for a really old WriteExcel version? Just when I tried using something like add_format, it complained add_format wasnt there (instead there is addformat), and the person already using WriteExcel installed it ages ago. Is it safe to use the same old code if I updated WriteExcel? If there is any flaws in doing so please let me know, no matter how small they are. Thanks.

Can you not just answer here? I've already signed up to this forum, but I can sign up to google groups at a later date hehe... please :-)

Hi John, I mean if I were to upgrade to the latest version would there be any errors from using his code as it is or would the old addformat's work still as they should normally? as well as having the updated add_format that I can use?

Don't think he used any bitmaps.

Don't worry if I have any further questions I will proceed to register to google groups, just currently looking a quick answer :-)
