Hook | Pull to refresh for the web

There is no public interface in the Magnification API that allows clients to apply filtering (other than color transforms). This used to be possible, but the MagSetImageScalingCallback API was deprecated in Windows 7:

This function works only when Desktop Window Manager (DWM) is off.

Even if it is still available, it will no longer work as designed. From Desktop Window Manager is always on:

In Windows 8, Desktop Window Manager (DWM) is always ON and cannot be disabled by end users and apps.

With that, you're pretty much out of luck trying to replicate the results of the Magnifier application's upscaler using the Magnification API.

The Magnifier application appears to be using undocumented API calls to accomplish the upscaling effects. Running dumpbin /IMPORTS magnify.exe | findstr "Mag" lists some of the public APIs, as well as the following:

• MagSetLensUseBitmapSmoothing
• MagSetFullscreenUseBitmapSmoothing

Unless you are willing to reverse-engineer those API calls, you're going to have to spend your time on another project, or look into a different solution.

A note on the upscaling algorithm: If you look closely you'll notice that the upscaled image doesn't exhibit any of the artifacts associated with smoothing algorithms.

The image isn't blurred in any way. Instead, it shows sharp edges everywhere. I don't know what upscaling algorithm is at work here. Wikipedia's entry on Pixel-art scaling algorithms lists some that have very similar properties. It might well be one of those, or a modified version thereof.

Because you are executing useEffect callback whenever data changes and you are changing data in useEffect callback.

Remove data as dependency.

Use this code to fix it

This was difficult for me to understand, so I wanted to share if anyone else has the same issue.

It seems that an async method will break a method chain, there's no way around that. And since fetch is asynchronous, await must be used, and in order for await to be used, the calling method must be declared async. Thus the method chain will be broken.

The way the method chain is called must be changed.

In my OP, I linked https://jsfiddle.net/47sfj3Lv/3/ as a much simpler version of the same problem. StackOverflow's 'fiddle' effectively blocks 'fetch' for security reasons, so I need to use JSFiddle for demonstration.

Here's a working version of the same code using then and how/why it works, and a slightly shorter version, because await can be specified with the the fetch, obviously.

The issue seems to be that you are already on the "/country/:name" path and are clicking to visit another country. The router correctly updates the URL in the address bar, but because CountryDetail is already mounted it neglects to recompute the item and allCountries state. This is because the useEffect hook only runs once when the component mounts.

The name param (match.params.name) is actually a dependency for the GET requests, it should be added to the useEffect hook's dependency array.

I have the dumb and answered my own question. I did not in fact try every variation with/without .columns.

You can do it by adding DISABLE_ESLINT_PLUGIN=true to the "build" in the "scripts" part in your package.json:

Hello I have found a solution. I had several instances running and therefore the npm start then selected a different port than I defined in the test. Have killed all processes on the port and restarted

You can turn off any specific rule like so:

I'm assuming you have missing dependencies on your code generation class path. Once you update your question, I'll update my answer.

jOOQ won't support your generated composite types in generated code out of the box, you'll still have to add forced type configurations for that, possibly embeddable type configurations:

• https://www.jooq.org/doc/latest/manual/code-generation/codegen-advanced/codegen-config-database/codegen-database-forced-types/
• https://www.jooq.org/doc/latest/manual/code-generation/codegen-embeddable-types/

Note that the JPADatabase offers a quick win by integrating with simple JPA defined schemas very quickly. It has its caveats. For best results, I recommend going DDL first (and generate both jOOQ code and JPA model from that), because it will be much easier to put your schema change management under version control, e.g. via Flyway or Liquibase.
