Self-updating Application with SHA1 check and FireDAC

- or basic self-improvement with room for improvement.

There are many ways to keep the users windows applications updated, like pushing them out via enterprise distribution setups, click-once, Squirrel (not the scripting language or the animal). But what if I just want the basics - and as simple as possible?

Disclaimer: This is not a post about security - even if SHA1 is mentioned - this is solely intended as an example on how an update process could be done in a controlled environment - like in-house distribution.

Integrating with your favorite CRM/ERP web based client

- or poor mans integration?

Sometimes you need to integrate to other systems in the organisation. And the ways of doing it always matters on which interfaces/skills/tools are at hand - but also whether you need a tight dependency and if you want or can customized anything on that client.

In the below example I will just illustrate how a standard Microsoft Dynamics 2016 CRM "Lookup Up Record" dialog can be used to link some other data/application that has interest in the CRM data - so that doing BI across systems might be more fun.
