rest content not appearing in Xamarin.forms examples - rest

I am experimenting with two of the examples ToDoRest and the XamarinForms3RestApiApp. I am looking specifically at the UWP client.
I have made sure that I have the same code on my computer as the examples in GIT.
When I run them they compile without error and the form comes up. However in both examples the existing data from the rest backend does not appear as content on the UWP page. clicking on the api link shows that the json formatted data does come up when accessed directly
In both cases its the 'vanilla' example on GIT -nothing changed.
Has anyone else experienced this on these examples?If so, what might be preventing data from showing?

Lit not working, not giving back anything from the custom web component

I'm trying to learn how to use lit as a dev tool for making web components and I'm having issues with making it run on my system.
In the documentation it states that you just need to run the command "npm i lit" on the folder of your project and after being successfully installed it should be running.
I did the "simple greeting" test also available on the documentation but it's returning me a blank page. I even copy-pasted both ts and html. Still blank page.
on my html, if I drill something into it, it shows on the page, so I know it's something regarding the custom web component (named simple-greeting).
I already did a course on native web components and I understand how it works, but I never worked with lit.
Isn't it just to import the necessary things from the respective library (like html, css, LitElement) and use it in TS?
Am I missing something? I am really confused and can't find anything online.
Thanks in advance.
It seems I forgot to run the web server. Still a long way to go, I guess.

How to reverse engineer a progressive web app ?

I found this free PWA https://www.the-qrcode-generator.com and now wonder how I could do one such myself.
Since I couldn't find any access to its source code I wondered if it'd be difficult to reverse engineer.
I'm interested in building a PWA with QRCode functionality.
This one was created with AngularJS v1.3.20. You can find the source in your console windows under Sources tab. You can easily beautify the code inside the window to make it readable.
If you want to know how they organized their rest API, the browser network tab will help a lot, just filter by XHR and examine all the call from the front end to be.
The front end is very hard to revers engineer, because most sites are served as minified bundles, so you can't see the original code.
You can however find some other information about what they used to build it, for example in the html source you can see some ng-* tags, which indicates that this is angular, you can also see that body has attribute data-ng-app meaning this is angularjs and so on.
For the QR logic you can see that there are no back end calls, meaning that it is written entirely in the client. I would search for already available solutions for that.

accessing XHR within google sheets

I've been using import functions a lot in my sports modeling, but I've never been able to figure out how to get past the issue of pulling information that is dynamically imported from another source.
For example, i'm trying to use importxml to pull the money line values in this link here: https://www.sportsbookreview.com/betting-odds/nfl-football/money-line/
I can get the information in the left columns up until "PINNACLE", and after research i now understand I can't get the rest of the information because it's not static on the page and I need to go to the source... how do I find the source of this information so I can pull it from there?
I tried inspecting the page, clicking on "network", clicking on "XHR", refreshing the page and previewing the results, but nothing seemed to match.
Am I looking in the wrong place?
The page uses websockets to download the data, so I don't think you could simulate it in Google spreadsheets using formulas (maybe it could be possible in a script). However in this particular case there is a 'classic view' variant of the page which includes all the data in its source:

Rest Console for Chrome won't let me input any info

I installed the Rest Console extension onto Chrome. I can't use this Rest Console for anything, because the only fields that accept text are 'Request URL' and 'Request Method'.
I ask here as there is no resources or community accessible for even simple instructions on how this extension works, and there are likely members of this community who have used this extension.
Use the Postman - REST Client it works perfectly!
your_url_to_post: Fill the URL
your_json_param: The name of the param that you'll pass you json
your_json_data: The json content
Don't forget to select x-www-form-urlencoded if you'll do a post

You should be able to enter text in the other field if you tick the checkbox associated to the field first.
I started having a similar issue myself (Forms wouldnt let me input data I could click them but thats as far as it went) across a lot of web pages to include my own php game and I know the form code hasnt changed at all before this issue started. I came across a article of someone else having a similar issue themselves that I was having and someone said that they needed position: relative on their forms that are not given specific instructions on positioning when dealing with google chrome. I have since made this change myself at www.immoralattack.com and the issue has stopped on that site but still continues on many others so its pretty safe to say that is the issue.
Its only happening on the dev build of chrome for me atleast and I hope this isnt something they plan on implementing on live or this will mess up alot of websites.
Also try turning off auto fill from chrome if its on, while I was looking for this bug I found alot of similar bugs but they delt with auto fill being on.

How can I program a button on an Access form to link to a browser window that looks up multiple addresses on Google Maps?

My problem is very similar to the one posted here:
http://www.utteraccess.com/forum/Plotting-Addresses-Maps-t1968130.html
except that thread never found any solutions. Basically, I'm working on an Access form that has a datasheet as a subform. Upon clicking a button on the main form I'm trying to make it so that a browser window opens up and, using the address columns from the spreadsheet data in the subform, plot all the address markers listed. I've looked up a lot of ways to attempt this but I've yet to find a way that seems to work.
I'm not even sure if it's possible to plot multiple markers on Google Maps, but according to research (and after trying it myself) it seems like it isn't, although I don't want to rule it out entirely because I'm still not 100% sure. However I know both Google Earth and batchgeo.com do allow this. I still want to try and do this on Google Maps, but if that doesn't work I want to try to do it using batchgeo.com and if that still doesn't work, then Google Earth (I don't want to make the user download external software if possible).
If it helps, from what I've read API's seem like a useful tool, though I'm not sure how to apply it to an Access form, it seems more like a way to embed to already existing websites.
I'd really appreciate if someone could help me figure out how to approach this problem!
Maybe this would help?

It is Excel but should be translatable.
Here is another example, this time using Access:

embed to already existing websites.
You're right. There's no way, that I'm aware of, to embed a Google Maps object in a form (like an ActiveX control). Microsoft MapPoint is a software product that lets you do Map integration by way of an ActiveX control (no need to use HTML and/or javascript).
What I usually do on a project like you're working on is I get my HTML page working the way I want it to, outside and independent of MS Access. You should be able to program and test the HTML file locally without having to use an actual web server. Just use something like NotePad++ or Sublime Text Editor 2 to write your HTML and Javascript and then open the file in your browser to see if it works. I'm quite sure you'll need to use Javascript in your HTML page to make this work. That's what the Google Maps API is all about.
After you have your webpage working, then you will have to go into Access and write code to create that web page on the fly with the address data for the current data set. You can just write it out to the Windows Temp folder and then open your browser control that that web page.
Julian Knight's answer links to more specifics on how to create the HTML page on the fly. It looks like gobble-de-gook, mostly because it is. Outputting HTML/Javascript/CSS from VBA is far less than optimal. This is why you troubleshoot it outside of Access, as much as you can.
