For a SQL Server developer wanting to create and implement a SSRS Delivery Extension needs a good step by step tutorial or example to follow.
However, I can only find one and as far as I tell it's either incomplete or not easy for a beginner to follow.
I want to create a Delivery Extension that renders a report in excel, password protect it and then email.
If anyone can point in the direction of others that would be most appreciated.
That doc has a link to Implementing a Delivery Extension, which links to SQL Server Reporting Services Product Samples, which has all the older SSRS code samples, including a custom delivery extension sample.
Although you might find it much easier to just have an external program that fetches an Excel doc through SSRS URL Access, and perform the additional delivery actions. A Delivery Extension is only necessary if you need to extend the SSRS engine to allow users to create subscriptions that use your Delivery method.
