I'd be a sliderule jockey for an engineering firm. That's almost what I ended up doing, anyway, only computer programming was hella more fun.

I have heard people say that only use partial classes when there is auto-generated code. I have found that I like to use them to separate different parts of the code that are pretty much independent, but not totally. It seems to make working on the code easier since functionality is separated by files, and this reduces the length of each file, which makes it easy to find what I am looking. If I created separate classes for the same thing, I would need to pass information to allow them to change access elements. I have also used, but did not implement, a case in an adapter where all the calls to get database data were through the same class, and each table had its own file which was a partial class. I thought this worked well, and kept code conflicts down. I just followed the pattern.

I do the same thing.

I do the same thing if a class has a large number of methods, but this is quite rare.
In most cases, my top level facade class will expose a number (e.g. half a dozen) of services, each of which offer specific functionality. This allows me to swap/evolve service provider implementations over time. This pattern has proved useful when maintaining this[^] app over several versions.

Anything for self-promotion. Ever the salesman.

But it's true. 
Maintaining a fairly large app (with a large active user base) over 12+ years is no easy feat. I need the benefit of a carefully thought out design to help me do that. I was just sharing my experience.

I was just teasing you, Ravi. I agree with your comments on the topic.

Hi Ravi-ji,
Assuming you have not published in depth about this strategy for app structure, I'd really appreciate seeing an article by you on this.
cheers, Bill

Dunno if it's worthy of an article, Bill-ji. Maybe a tip, at best?
It isn't something I designed - just a pattern I employ. But I'll tipify it if you think it's worth doing.

Sukria,
I accept tips

OK.
But you're giving me more credit for my knowledge of Hindi (and software engineering) than I'm due.

I use them extensively. Particularly for library routines.
.net 1 should not have been released without them.

Never having used one I now see an immediate use for them. I have a dashboard with multiple tabs, all the data is related but I got annoyed by the size of the code base and split the 3rd tab out to a UC. Now I see I should have create a partial class.
Never underestimate the power of human stupidity

Usually when I have tabs I split out into separate classes, but partial classes seems like I good option
|
|
|
|

Partial classes is a good thing, but like anything it can be abused.
I have inherited an application with thousands of partial classes spread over just a few files partitioned by funtionality.
If I ever meet the programmer I'll teach him generics with a drill and a cactus.

For a particular WinForm app, I have a lot of controls on the main page. I use partial classes to break up the handling of the control events into their logical groups.
Otherwise, I never use partial classes, and instead use a publisher/subscriber pattern to communicate between instances, which also has the advantages of:
1) letting me hook in logging so I can see what the heck is going on
2) process intercommunication asynchronously, as the pub/sub I use can make message handler call on a separate thread
3) better exception handling, as the pub/sub will wrap the message handler call in a try-catch and log exceptions
4) because the exception handler uses the pub/sub itself to log the exception, I get can wire up other services, like an email notification, when errors occur
5) and the pub/sub instantiates the receiver class, so I'm enforcing completely isolated processing, which is great for thread safety.
So effectively, all the things that actually do non-UI things become services, and I often write them as runtime loaded modules that register themselves in the pub/sub, which is cool because I can then easily mock the services, change the business logic by loading a different module that implements different behaviors, extend the behaviors simply by adding new modules that handle the same messages, and so forth.
So there, in a nutshell, you have The Clifton Method[^].

Update: The contest has been extended to Aug 7! We know there's a couple of contestants who needed a little extra time so make the most of the extra week and get your entries in.
Our Internet of Things Article Challenge[^] is on and we've had a few questions I thought I may as well answer here:
- Any language, any platform. We're truly not fussed.
- It's about IoT which means connected devices. IMO there's no sensible definitive explanation of IoT: it's essentially just a label for technologies that connect "non-computer" devices with other devices or computers in order to achieve automation or sensing. You connect your thermostat to a weather service to get it to work out when to turn up the AC. You connect your burglar alarm and cameras to your phone so you can rest easy on holidays. If your idea is about connecting devices it's good to go.
- We need code. A discussion about your commercial app is great, but if your article doesn't actually allow someone to get down and get coding then it's not really a tutorial
- We want applications but it doesn't have to be a perfect, completed, packaged app you can sell. We're only after apps that run, that do something. Anything. Sprinkle it with bugs and build someting cute and pointless. It's the educational factor that's important.
This is really about having some fun with connected devices.
cheers

My mom is heading up to O'Hare to pick up a rescue dog coming from Europe, and her vehicle's (a 2016 Ford Explorer) GPS is off by AT LEAST 1/4 mile, as it told her to take an exit AFTER she passed it! I noticed this offset before (the little car icon would jump around), but usually it would sort itself out within a few seconds. I think the receiver may not be working correctly. Now it will take her AT LEAST another hour to get there thanks to traffic! And the plane has already landed!

Ford GPS? Turn it off and buy a Garmin (with a lifetime map/traffic subscription)!

Not enough money to do so right now. 
Seriously, though. Her Nokia phone gets better accuracy!

Gotcha.
I wouldn't pay extra for a GPS package if I bought a car. My $150 Garmin works wonders and is portable to boot. Plus a lifetime subscription of updated maps Hard to go wrong with that. Just sayin'.

The car was cheaper than a 2015 version with no GPS!
