UWP printing failure: 0x80040154 - printing

I've seen a complete failure of the ability to print from UWP apps on my PC, which has halted development.
The error that appears is 0x80040154. All printers are affected. No traditional steps to repair have been successful.
Desktop applications and modern Windows apps, like Mail, are unaffected. Only UWP access to printers.
I suspect that some permission relating to COM interaction between UWP and a Microsoft print interface has been damaged, but I've not a clue how to diagnose and repair. Has anyone seem anything similar to this and know how to dx and repair? Thanks.

How can I inspect element in an iPhone X's browser?

I have a CSS bug (visual difference) that seems to happen only in iPhone X devices.
what I would usually do in cases like these is use the inspector tool in the browser the bug occurs to find the rule I wrote that is not cross browser, and do a trial and error in the inspector tool until I find what works cross browser and cross platform.
knowing that iPhone uses safari browser - I installed safari on my windows PC but couldn't reproduce the bug.
how can I simulate a browser in a iPhone on my windows PC? or is there another way to find the quirk in this case in order to fix it?
I can't afford a mac.
I have windows 10 on my PC but can also use a linux distribution if needed.
also, this cannot be debugged in a cloud because the security team won't allow the code to be hosted on an external cloud at the stage of development.
As far as I know, your best/cheapest approach would be to run MacOS within a Virtual Machine and then perform the steps Neal suggested.
But keep in mind that you need to run the network config of your Virtual Machine in "Bridge Mode" otherwise your virtual macos can't see any devices on your network.

Delphi 10.2.2 App Tethering with Bluetooth how?

I use app tethering with Delphi between Android and Windows since Seattle and now with Tokyo 10.2.2 and it works quite well across WLAN. The only problems arise from customers that sometime delete custom rules in the Windows firewall so that the devices cannot find each other anymore.
Because of that support effort I would like to additionally offer bluetooth between the two devices but I cannot get it up and running. The Embarcadero documentation is not very helpful either.
What I tried so far (based on the solution working with WLAN):
Bluetooth Pair the phone with the PC
Switch both sides from "Network" Protocol (what ist UDP Broadcast) to "Bluetooth"
Added a Bluetooth component on both sides and activated it (it has no more settings). Also doesnt work without it.
When closing the PC application I get an EBluetoothException saying "cannot establish connection" that's all.
The devices do not discover each other. Perhaps I am missing one important step. So if anyone has bluetooth app tethering up and running I would be grateful if he shared his experiences here!
Thanks!

Run Microsot Internet Explorer inside an iOS Application

Is there any way to run Internet Explorer inside an iOS Application? I am looking for a component, like WebView, which be able to open IE websites.
Thanks.
The shortest answer is no, there's no IE for iPhone or iPad. Sorry to
tell you this, Internet Explorer lovers or those of you who are
required to use it, but there never will be.
There are two key reasons for this:
Microsoft stopped making Internet Explorer for the Mac in 2006. If the
company doesn't develop IE for the Mac, it seems very unlikely that
Microsoft would suddenly bring IE to the iPhone More importantly,
Microsoft doesn't make IE for any operating system anymore. The
company retired Internet Explorer completely in 2015 and replaced it
with a new browser called Edge.

Debugging GWT on tablets (Android, iPad)

We're running with a strange error running our GWT application on tablets (both iPad and Android). It's a touch event the one producing the error ("undefined is not an object")
How can you debug a GWT application for this scenario. We need to produce tablet touch events or run the GWT code on development mode in the tablet.
A couple options that have helped us debug GWT apps on the iPad:
a Windows machine with a touchscreen (we have this one at the office)
Java logging + the popup log panel (or remote logging) (Google Developer's Guide)
Firebug Lite - this may not help with this specific problem, but maybe in the future. :)
Hope some of these help.
I believe you can debug a compiled GWT application (works for me using GWT 2.4).
You need to have the GWT Developer Plugin installed in the tablet browser. I don't know if it's possible but if it is, all you need to do is append the gwt.codesvr=<yourDevMachineIp>:<yourDevModePort> query parameter to your app URL while running Dev Mode for your app in Eclipse.
Disclaimer: I've only tried this with a compiled app in a browser running on the same machine as my Eclipse IDE. If you're successful, please post a brief note here.

Debug windows phone 7 via Visual Studio without internet

I'm debugging a windows phone 7 application using Visual Studio, and I'm trying to catch an exception that's thrown when the connection suddenly disappears. I'm looking for a solution that's much easier than just pulling out my ethernet cable every time I navigate with a webbrowser...
Thanks!
No. You don't need to.
I've done this by setting Fiddler as a proxy for the emulator, and closing it when I want to simulate no internet connection.
If you want to try this solution, you will find this link helpful.
