The solution is don't buy printers that use a multi-color ink cartridge. Yes, the printers will be more expensive but the lower ink costs, especially for heavy printer users, will cover it.

You're right.
Mine is a WF 2760 & I bought it explicitly because it uses separate ink cartridges for all 4 colors (black, yellow, cyan, magenta).
You can replace any one that runs low without the others buggering up.

Your only missing the Black...
Just print on Black Epson Paper... You'll be fine...

I plan to add logging into my Windows Form application.
NLog is still looking good for me in my case.
are there any people still using it from codeproject community?

We are using Log4Net, which I'm not very fond of, never tried NLog but it seems a better choice.

your input is always insightful for me.
I used this post as a jump start.

I use nlog - I prefer it to log4net. It's very easily configured, and comes with pre-canned formatters for most situations that you can think of.

The better question is, should I do logging? Seriously. I'm not being facetious. Logging sounds great until, as I've always experienced, there are reams of output to wade through and nobody bothers and they even forget there's logging going on.
What is it you need to log, and when exactly does it need to be logged?
Now granted, years ago my team added logging to every user action (this was a DOS desktop app at that) which was enabled in "QA" mode. We logged the tester's activity, we were able to play it back, and when they said "I did x, y, and z" we could look at the log and say, "no, you did x, A and z" and they were stunned. So that kind of logging was quite useful!

I think logging exceptions and/or unexpected errors is a must, especially for debugging purposes.
I am not really into informational logging in a Prod environment; maybe, in dev, but not prod.
we have a pageview table that stores all the page view stuff for troubleshooting and metrics for business team.

Agreed. I've actually become rather brutal about it - I send an email to myself when something critical blows up. I have a few Outlook rules as a result.

your question is great: my first step is to log some data files that are empty. I downloaded these kinds of files using web API.
I need to know what kind of files are empty.
later on I will go deeper to record exceptions.

Generally it is useful to use logging on different levels and enable/disable the levels as needed. There might be no need to see any informational messages in certain applications until there is a certain error that you want to inspect. In other cases it might be useful to see verbose things like "user x did action y" all the time. As a rule of thumb I would only log things to which I had a specific use-case in mind or things I knew from experience that they help down the line.
Regarding if logging should be done in general: Yes, please. As someone who writes and uses tools that go through logs all the time I am very grateful for applications that log well - meaning not too much, but at least all errors and warnings.
If you use Windows then you could think about writing events to an eventlog instead of writing text files tho.

Having supported numerous systems, I can tell you that Logging Matters.
And with current day abilities to create date/time files, and delete files over 7 days old, etc.
I am fine.
The one issue we ran into was needing INSANE levels of logging to track down a DEEP bug.
7 Days worth of this would overwhelm ANY system. (Think of it as turning on Kernel Debugging)
So, we implemented an in-memory circular log for that level of debugging, and NEVER wrote it to disk,
until an exception occurred. So, we had all of our "good logging", and then we had an INSANE level,
that would usually cover the last couple of minutes before an exception. (to be clear, we trapped the exception,
and added that logging information to the output, along with a stack trace).
Within a few days we had a rare problem isolated (something that happened about every 10,000 sessions).
Yes, we need logging. But be careful, I've seen people logging DB connection credentials! OUCH!

just write message into a text file?
it turns out my case is simple. I just dump my messages into a text file, which file name is with timestamp.

Pretty much. Maybe
I don't use logging packages (well, I did in another development life). I live in the embedded world, and for the last slate of products, we rolled our own. I won't get into writing stuff to the file system and worrying about loss of power. What I will tell you to do is to use a comma delimited format for your logging. Think ahead of time what information is useful to you and set up standards. Error levels, associated data. But keep it all comma delimited.
Being able to suck this into Excel is priceless.

Why would I use Azure when speed is dependent on my Internet connection, and Sql Server on my computer, or network is much faster (I think)?

Depends on what you want.
If you want a mobile DB, that can be accessed by any device, any time, over LAN, WAN, mobile or wired connection then Azure is one way to go.
If you want security, speed, and low cost, then ... ummm ... it probably isn't ...

Do not think of Azure as an alternative to your development computer.
It is an alternative to the server (farm) hosting your application.
And while Azure and AWS can run virtual machines, it is an outdated way of doing software deployment and you will have limited benefit from running those in Azure.
Docker will start to present some benefits (specifically if you need to run on-prem as well), but a "cloud native" architecture where you use Azure storage solutions, authentications, serverless, messagebus, ... is where you see the full benefit.

Hey, can you elaborate a bit on how docker will give benefits when running on premis? I use docker a lot in my dev environment but not for deploying to production.
