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.

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.
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.
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.
Has anyone made explorercanvas work with GWT? Can you share the exact code?
I see a lot of references to explorercanvas with GWT. For example: http://code.google.com/p/explorercanvas/wiki/Instructions But these are always filled with caveats and complaints. I haven't seen any complete solutions.
Yeah I have done so for a project. I created a module which you can inherit and use in your gwt application and use the GWT Canvas class to write your code. You can see the details in my blog.
http://ummeessa.blogspot.com/2011/09/gwtcanvas-on-ie7-and-8.html
Hope the blog will help you creating your own module.
I have used my module in a project to create charts using canvas. It works fine in IE7/8 and I am sure there should be no issues. Everything which is supported by excanvas works in my module.
JAPopup is a handy plugin for Joomla to render Youtube videos in a Modal Window so user cannot click on multiple Youtube videos at the same time. The website URL is www.multicorewareinc.com/29042 (hast not gone live yet!). If I use a standard Joomla template such as JA_Parity or rhuk_mllkyway, JAPopup plugin works fine. But instead if I use Template 29042 from template-help.com, JAPopup hangs up. I compared the index.php files of a working template (such as rhuk_milkyway) and Template 29042 and as far as I can tell, 29042 uses Javascript extensively and there appears to be an issue when it comes to launching JAPopup (which too is based on Javascript). I put print statements in all the JAPopup modules and verified that the code was getting executed in either templates. So I am at a loss as to why JAPopup won't execute. If anyone has a suggestion, I would be grateful. Once I fix this, I plan on publishing the problem and the fix on my web-site, www.sreeiyer.com.
What does Firebug say? It's obviously a jscript conflict so start narrowing down the options - does the template use jQuery or another library? Does JAPopup use a library? You can also remove the scripting from the template and start adding it back until the error comes back, then you know what needs to be rewritten.
