Can I make CNC Editor with HTML5? - html

I would like to make my own CNC Editor.
I am looking for some guidance. I don’t know if it is even possible with HTML5. But it would be great if I can. If possible, please list what I should research and learn.
I don’t need it to be online accessible, I will only have it on my computer. I will be accessing it via local network from multiple different computers. I don’t want it accessing the internet, because it’s not always available.
Desired Features:
⁃ Read and Write files with different extensions (all files used are easily opened in notepad)
⁃ Store and retrieve data from a simple database file.
⁃ Make calculations
⁃ Have a text Editor window
⁃ Have a Display area for simple vector graphics depending on data loaded and provided by user.

It is possible but requires a lot of work. I would say that these are technologies you would need to master in order to pull this off:
Node.js (use express.js) - for storing and retrieving files from database and for reading/writing local files with extensions you want (server-side)
Vue.js or Angular.js or React - for building frontend interface to manipulate your vector graphics. It can also do calculations and It's good with svgs and that kind of stuff.
Electron.js (not mandatory) - it wraps it in native-app like experience. This framework actually gives you ability to write desktop apps for any os and arch.
So as I said, It would be a lot of work but its possible in the end.
Funny coincidence is that my brother is planning to build CNC machine so I might be doing this as well in next couple of months. Feel free to contact me if you need any further help!
UPDATE: You cant do it with just HTML5. It would be like trying to make wooden space shuttle.

Using a database in html without a server

I have a question regarding the client-side possibilities of a html webpage. I am currently working on my masters-thesis in aerospace engineering and plan to develop a design-catalog for inspiration. I chose html for this purpose, because I have a basic understanding, want to learn more and love the possibility of changing the style (e.g. width, height, padding, …) of all elements with a single command.
Unfortunately, there is no way of installing a local server or any other kind of software on the university computers. Besides, there is no way I get my colleagues (supervisor, Professor) to run additional software just to look at my catalog. Publishing the webpage on the intranet or internet is totally out of the question. The only possibility I have is using a browser (Firefox) and an Editor.
I thought about two different approaches:
Consider having a (Windows) folder containing images. Is it in any way possible to load all images of this specific folder into a webpage without using a server-side or installing any kind of software?
This would be even better: Is it in any way possible to make a website load data from a database into its own html code? I would like to be able to load only specific elements, e.g. all Designs with 2 Degrees of Freedom, or only load all images.
Any kind of database! I don't care if it is mySQL, MariaDB, Excel or even a CSV file or something completely different.
Security of the code is not an issue. The data is sensitive, but I have full control over the database and code. It is a no point planned to publish the webpage or host it somewhere.
I would appreciate any kind of comment whether this is in any way possible, or whether I definitely need a server (e.g. xampp) to realize my approaches. If there is no possibility I would need to implement every image by hand or scratch the idea of the design catalogue.
Thank you in advance!

windows tool to view website client content without browser

Per the title, I am looking for a tool or some sort of initiative that's already been undertaken by other developers to simply grab data off of websites so one can navigate them without looking at them in the browser. I am fully aware of how most pages work so what I would like to do is just look at the data that's being pulled from them per windows technology that's already (hopefully) been written. Does this make sense? Here is an example of what I would like to see in a tool:
a windows interface that gives me data about a webpage (menus, submenus,
button names/captions, etc...
be able to execute transactions on those pages by specifying what to do
through the tool's interface (click button, download image, etc..)
does anyone know of a tool out there to do such things?
The closest "program" that comes to mind is
WWW::Mechanize
Advertised as
Handy web browsing in a Perl object
This can in fact be used on Windows, however you
will need Perl.

Browser, upload large file

I'm looking for a way to allow a user to upload a large file (~1gb) to my unix server using a web page and browser.
There are a lot of examples that illustrate how to do this with a traditional post request, however this doesn't seem like a good idea when the file is this large.
I'm looking for recommendations on the best approach.
Bonus points if the method includes a way of providing progress information to the user.
For now security is not a major concern, as most users who will be using the service can be trusted. We can also assume that the connection between client and host will not be interrupted (or if it is they have to start over).
We can also assume the user is running a browser of supporting most modern features (JavaScript, Flash, etc)
edit
No language requirements. Just looking for the best solution.
There are several ways to handle this,
1. Flash Uploader
Theres plenty of flash uploaders to improve the users GUI so that they can examine the process and the process factors such as time left, KB Done etc.
This is very good if you understand how to improve Flash source code for later developments.
2. Ajax
Theres a few ways using Ajax and PHP (although PHP Does not support it) you can use Perl module to accomplish the same thing http://pecl.php.net/package/uploadprogress, This is only if you wish to show percentage information etc.
3 Basic Javascript.
This method would be just the regular form, but with some ajax styling so when the form is submitted you can show a basic loader saying please wait while you send us the file...
If your using asp, you can take a look at: http://neatupload.codeplex.com/
Hope theres some good information to get you on your way.

Not sure about your language requirements, but you can look e.g. into
http://pypi.python.org/pypi/gp.fileupload/
Supports progress information also, btw.
I have used the dojo FileUploader widget to reliably upload audio files greater than a gigabyte with a progress bar. Though you said security was not an issue, I'd like to say that I got HTTPS uploads w/cookie based authentication hooked up flawlessly.

Adding text / input box rendering to Access for a guided user interface experience

For software used in a call centre guiding agents through a set script they must follow while on telephone calls, with the script branching dependant on answers to questions given - My system uses a MS Access / VBA front end (isnt web based due to speed, phone integration), 'call scripting' is coded in VBA when needed, but what if i want move to a more complete solution?
Is hosting a HTML/ms webbrowser control the obvious platform to build call scripting on?
A manager view will also be needed allowing managers to create scripts, divide it into parts, specify routing rules that determines the path through the script, link input boxes (ie question answers) back to database fields, specify validation rules as well.
Thinking about the complexities of building the manager view that translates the intended script into HTML/Javascript, is creating my own simple doc description language with tags for just the features i need and a 'rendering engine' in VBA a solution you might consider for this?
Ive thought about creating scripts out of standard Access controls, using relational table structure to hold the info of what controls relate to what parts of scripts, validation, routing options etc but i think due to Access' lack of runtime control creation this will be more painful than a rendering engine that takes a script written in my own doc desc language and displaying it.
What suggestions have you for the implementation of this?
The actual user interface requirements of the user-facing part of your system seem to be pretty minimal (ask question, get answer, branch to "next" question). I don't think there's any "obvious" platform to use. As always, a browser based system makes it easier for geographically scattered users to use a centralized system but will probably cost more in terms of development.
The manager-facing part of the application is more interesting and for that I'd probably suggest a desktop application rather than a browser based one. I can see this relying on a lot of drag-and-drop and line-drawing type functionality and that kind of stuff is still easier to do on the desktop, at least in my opinion.
Assuming that you can clearly define the kinds of question routing and decision points that a script has, and these decisions are relatively simple, I probably would write your own specification for how a survey is represented. The manager-facing application would create, edit, and save a specification and the user-facing application would read and step through one.
Given my personal skill set, I'd probably write both applications in Delphi, develop an XML format to represent the survey specification, and consider either XML or relational storage for the back end depending on what you actually wind up doing with the data.
I'm inclined to agree that a web interface is optimal for something like this, however WPF is a great alternative as well with many of the advantages of a web interface along with the power of a desktop application. Both web and WPF would give you considerable amount of control over how the application looks and feels, leveraged with all the power of the .NET framework. One drawback of a web app is that you have less ability to interact with the phone system directly, but I'm sure that's a problem that can be mitigated fairly easily with some AJAX. A big plus for the web platform option is that you'll have access to tons of client-side interactivity libraries like jQuery, which will allow you to polish the application with greater ease; with WPF you would likely find yourself paying for a lot of the fancy UI controls.
There is quite a few survey and question (test creating) systems built in access. I don’t see any real issues in using access as opposed to whatever system.
The advantage of HTML or text based systems is they tend to support a more dynamic type of screens.
On the other hand, for questions and display of text, in access a great trick is to place a sub-form control on a form, and then at runtime simply “set” what form is to be displayed in that sub-form (the source object properity). In fact, in access 2010, the nav control does exactly that and it displays forms as a sub-form.
Also for access 2010 we can create web based applications. In this video you can see that the half way mark, I switch to running the application in a standard browser.
http://www.youtube.com/watch?v=AU4mH0jPntI
However, the above means little here, as I not sure what you mean by some type of rendering engine. Each question + response is simply going to be some text on a screen, and thus you can simply display/change that text by changing the underlying reocrdset.
And, if you want nice formatted text with different fonts etc, well access 2007 now has support for rich text (markup text). So I don’t think you really need dynamic screen creating. Between changing the record source to display whatever text you want, and that of being able to display different forms (templates) on the fly by changing the sub-forms “source object”, you can well change part of your screen to display different text boxes with very little code.
On the other hand, if you have all of the .net tools and want to create a browser based application then you are free to do so. I suppose you could also wait for access 2010 to create a browser application.
If you willing to keep this simple, then access is a great choice. If you need a browser based application, then I don't access is the choice here.

How to take screenshot of rendered HTML page

Our web analytics package includes detailed information about user's activity within a page, and we show (click/scroll/interaction) visualizations in an overlay atop the web page. Currently this is an IFrame containing a live rendering of the page.
Since pages change over time, older data no longer corresponds to the current layout of the page. We would like to run a spider to occasionally take snapshots of the pages, allowing us to maintain a record of interactions with various versions of the page.
We have a working implementation of this (Linux), but the snapshot process is a hideous Python/JavaScript/HTML hack which opens a Firefox window, screenshotting and scrolling and merging and saving to a file. This requires us to install the X stack on our normally headless servers, and takes over a minute per page.
We would prefer a headless implementation with performance closer to that of the rendering time in a regular web browser, but haven't found anything.
There's some movement towards building something using Mozilla source as a starting point, but that seems like overkill to me, as well as a maintenance nightmare if we try to keep it up to date.
Suggestions?
An article on Digital Inspiration points towards CutyCapt which is cross-platform and uses the Webkit rendering engine as well as IECapt which uses the present IE rendering engine and requires Windows, natch. Nothing off the top of my head which uses Gecko, Firefox's rendering engine.
I doubt you're going to be able to get away from X, however. Since CutyCapt requires Qt, it requires either X or a Windows installation. And, similarly, IECapt will require Windows (or Wine if you want to try to run it under Linux, and then you're back to needing X). I doubt you'll be able to find a rendering engine which doesn't require Qt, Gtk, GDI, or Cocoa, and therefore requires a full install of display libraries.
Why not store the HTML that is sent out to the client? You could then use that to redisplay in a webbrowser as a page to show what it looked like.
Using your webanalytics data about use actions, you could they use that to default the combo boxes, fields etc to the values the client would have had, even change the CSS on buttons, etc, to mark them as being pushed.
As a benefit, you don't need the X stack, don't need to do any crawling or storing of images.
EDIT (Re Andrew Moore):
This is were you store the current CSS/images under a version number. Place an easily parsable version number in a comment in the HTML. If you change your CSS/images and use the existing names, increment the version number in the HTML output sent out.
The system that stores the HTML will know that it needs to grab a new copy and store under a new number. When redisplaying, it simply uses the version number to determine which CSS/image set to use.
We currently have a system here that uses a very similiar system so we can track users actions and provide better support when they call our help desk, as they can bring up the users session and follow what they did, even some-what live.
you can even code it to auto-censor sensitive fields when it is stored.
depending on the specifics of your needs perhaps you could get away with using one of the many free webpage thumbnail services? snapcasa, for example lets you generate thousands per month / no charge no advertizing .. (not ever used, just googled 'free thumbnail service') to find this.
just a thot
