Is there a CEF(Chromium Embedded Framework) based chm viewer? - windows

Windows self integrated CHM viewer is fine, but it always use internal Internet Explorer, For some computers that have low version of Internet Explorer do not support advanced HTML and CSS features.
So is there some alternative software for CHM viewer?

There are a few alternatives to the Microsoft CHM Help viewer with various levels of quality and evolution throughout the years. It is highly plausible that the cross-platform ones such as Okular or xCHM are using a WebKit based web-browser to display the topic content. WebKit is the browser engine used by Google Chrome and therefore CEF.
That being said, a technical writer should carefully think if it makes sense to use a third-party CHM help viewer, as it would imply:
The installation of a potentially large and unknown application on the end-user's computer;
Possible difficulties for the end-user to operate this new application, which would be dramatic as its purpose is to help her in the first place;
The possibility that the installation or use of this new application "steals" the .CHM extension and opens every CHM help file in the future, making it a nightmare for novice users;
Extensive tests to make sure that the chosen application correctly works with the CHM help files as they evolve;
One possible solution would be to consider another documentation format such as an online HTML documentation web-site (which can be opened using any web-browser), or a cross-platform QT help file (which would require the installation of the Qt framework).
A single source help authoring tool such as HelpNDoc, RoboHelp or Flare can be used to simplify the process of creating multiple documentation formats for different audiences: most of them can produce basic CHM help file for the Windows operating system, as well as full-featured HTML documentation web-sites and printable Word or PDF manuals without too much extra efforts.

Desktop application using Firefox WebExtensions

I am working on a XUL desktop application, where I use the browser tag and load a URL in that tag within the desktop application.
However, some websites display as old format and according to Mozilla, XUL is deprecated and will not be useable at the end of 2017. I want to build the application with the latest technology: WebExtensions.
I have searched many examples on the usage of WebExtensions, but all are working within the browser. Can I make a standalone desktop application just like XUL, but using WebExtensions?
If yes, then please give me some hints on how to get started.
If no, is any alternative for the same requirement available?
Webextensions are fairly limited in their scope. Even if there was an application runtime utilising them, you probably wouldn't get much use out of them due to the restrictive isolation from the host system.
Strictly speaking not webextensions, albeit very similar:
The Electron framework/runtime*
Someone at Mozilla is also working on an alternative dubbed "Positron"** though that software's future is uncertain and there is a chance he might abandon it for an entirely new, highly simplified project (at least that's what I gathered from my conversation with him on Github).

UIAutomation event for when PDF downloaded in Internet Explorer

I am trying to handle an event for when a PDF has downloaded and been fully displayed in Internet Explorer.
Which UIAutomation event will handle this?
If you are referring to the UIAutomation object in the .NET Framework, it supports managed code. Internet Explorer is written in C++ as unmanaged code. Some folks have managed to write extensions using managed code, in spite of clear advice to the contrary, however, I've not heard of anyone successfully controlling IE using managed code.
Earlier versions of IE could be automated using COM interfaces or VBA objects, however, these features have been increasing deprecated over the years.
In addition, few of those interfaces supported extensions. (PDF is not a natively supported file type for Internet Explorer, so automation would depend on the surfaces exposed by the application registered to handle PDF mime types for the individual user.)
Since Edge is now the official browser, it's unlikely that IE will be updated to support managed code extensions. Note that Edge does not currently support extensions and little information is available describing when, or if, that will change. (There have been vague promises in the past, but little additional information.)
If you're trying to accomplish a specific effect, consider posting a more specific question, one showing:
The code that you're trying to use,
The effect you're trying to achieve, and
The behavior you're seeing instead.
Hope this helps...

Web technologies in GUI apps

What's your experience in using web technologies (HTML, XML, CSS, JavaScript) to implement part of the functionality of a GUI application? Pros and cons, please.
No servers, relational databases, AJAX, or cookies for session management, nor an existing webapp either, but rather a GUI app that uses web widgets (like Qt WebKit) to render and handle substantial parts of the UI, while taking advantage of a GUI framework to achieve an even richer interaction and better desktop integration.
I've already validated that the approach is possible using PyQt. Content can be rendered from the file system or from strings, and URL requests (images or clicks) can be captured and served by the form's event handlers. CSS and JavaScript are supported, perhaps with some limitations.
# ...
self.webView.page().setLinkDelegationPolicy(
QtWebKit.QWebPage.DelegateExternalLinks
)
#...
class TotiMainWindow(QtGui.QMainWindow):
def linkClicked(self, url):
pass # events arrive here
Note: This question is different from this one and this one made before, among other things because there is no requirement to use web technologies on the GUI, but there is the requirement that the application should work without a network connection available, and should integrate well with the default desktop over different platforms, without previous infrastructure requirements (no .NET, Java, browsers, or database servers).
Note: I posted a different version of this question on PMS but found very little experience with this approach there.
Closing Note
I just found most of the information I was looking for in a series of blog posts by André Pareis.
I think the largest advantage to using web markup like HTML/CSS and other web technologies is that desktop apps may very well have their days numbered.
As we speak, Google engineers are working on the Chromium OS, which essentially consists of a single GUI application... the browser...
Now, while nothing may never actually come of it, there is clearly a rising trend in the number of applications accessible through a web browser, accessible anywhere. It seems to me that this is the future of application development.
By using these technologies, this becomes one less headache you have to deal with when or if you determine that your app should be available as a web application.
Update: A few years ago, we developed an Agent Desktop for our call center that is essentially a local application that opens sockets to integrate with the phone system. The user interface the agents use is built with HTML, CSS, and JavaScript, and the experience is stunning. When we released our latest update in 2010 with a professional CSS redesign, our agents were all very impressed with not only how easy it was to interact but also how easy it was to use.
In the future we will port this 100% to the browser, but for now it needs to be a local application because of the COM integration with the phone system.
We did exactly this for a project back when Windows XP was new.
This gave my team several benefits:
A good-looking UI with relatively little effort
Easily change the style of the UI in a consistent manner using CSS
Relatively simple integration with C++ (invoking functions from the ui and vice versa)
The drawbacks we saw were:
Some not-so-good firewalls considered accessing internal resources (ie other html pages in the ui) to be a web request
Adding and accessing the needed resources could in some cases be a bit cumbersome
It was possible set properties in Internet Explorer that would prevent JS from running in the application
Note that some of Windows XP:s programs are using this approach.
This probably works best with small, more Wizard-like parts of the ui (which our ui consisted almost entirely of).
I have since then not really been involved in ui projects, so I cannot really tell you whether this approach is still valid... I know that MFC-based applications will let you use HTML-based dialogs though.
In a similar situation in 2005 I created a stand-alone webapp using XForms, CSS, JavaScript, XML and XML Schema for offline data retrieval and verification. With a good XForms -> HTML + JS transformer (Chiba) it did the job with no bug fixes after the initial release. It was used for 6-12 months (IIRC) by about a dozen engineers for a project gathering test data in the tunnel of the Large Hadron Collider. The biggest surprise of that project was just how much you get for free when going for a web platform, even for offline use. Highly recommended.
The major problem is that it reduces your development speed, or the quality of your user interface. A lot. Unless you're using Seaside, it is much faster to develop a desktop app.
There is quite some number of applications built on top of Mozilla platform. It isn't 100% web technology, as instead of HTML you use XML based XUL, but the rest is indeed web stack (JavaScript, CSS). The most successful of these it the OpenKomodo and it's commercial big brother Komodo IDE.
On the other hand, as far as Qt goes, the newest version 4.7 you can build GUI using QML language. Don't let the name mislead you, it's not markup, it acctually JavaScript with app-specific extensions.

Editor for end user documentation in C# WinForm app

I'm developing a WinForm app in c# 4.0 and would like other (non-developer) colleagues to contribute writing a context sensitive end-user helpfile. First I thought I could use "HTML Help Workshop" from Microsoft, but it seems outdated (Vista and Windows 7 not supported).
Then I've looked at Sandcastle, but the documentation is lacking and I wonder if it is suitable for non-technical users to write end-user documentation.
So I read about RoboHelp, but it's way to expensive for me.
I'm getting lost in all the information that is available about helpfiles. Can someone help give some best practices or information on what tools to use and what output format I should target (still chm or other).
Great question. I like your idea of non-developers contributing to the end-user documentation.
This idea might motivate users and testers of your application to easily contribute to the documentation.
The first thing that comes to my mind, is using a some sort of wiki engine. You could build a simple function in your WinForm application, that fires up a browser and directs in to the wiki. You could use the context from which it is called to build up an url; e.g. http://dev-wiki.mycompany.com/LoginForm?action=edit. Here the name of the form ("LoginForm") is used in the url of a wiki page.
Alternatively, you could simply use the embedded web browser control for WinForms to access the wiki. That would look something like:
var url = GetWikiUrl(myForm);
browserControl.Navigate(url);
This would be very easy to embed in your application.
In a controlled (office) environment, this would be very easy to set up. In you production environment it might be a bit more difficult, but still doable. It might leverage some end-user contributions too.
For writing documentation, I use sphinx.
It lets you document in plain text and has various output formats (chm, html, pdf etc.).
Some of these (chm, html) can be used as context-sensitive help sources.
However simple, the sphinx user-interface (text editor and make file) might not be suitable for non-technical users.
I would recommend to use Help+Manual for creating CHM documentation. It's similar to MS Word and any PC user can start to contribute doc development after short education.
But this tool isn't free :(

What Software Do You Use To Create Sitemaps / Site Structure For Large Sites?

Just wondering what software you use to create a visual sitemap / site structure representation before you start big sites?
I am looking to map out a large site, but cannot find any good software to help me map the site visually (And in pages/categories)..
Maybe SketchFlow http://electricbeach.org/?p=145 ? which is included in the Expression Blend Trial http://www.microsoft.com/downloads/details.aspx?FamilyID=92E1DB7A-5D36-449B-8C6B-D25F078F3609&displaylang=en
I strongly suggest taking a look at this tool: http://www.balsamiq.com/products/mockups
The Balsamiq tool is the best for doing mockups (i assume this is what you are referring too when talking about sitemaps before you start...). With this software you can quickly generate a working wireframe of what ever you are creating. So much functionality that you can actually share it with your client to get some good sign offs prior to typing the first bit of code.
Very powerful!
And the other one...just shown at the last MIX09 is SketchFlow. Couldn't remember it to save my life. This is a WAY COOL tool for site maps and UI mock up. I was trying to find you the actual MIX presentation as it is super cool to watch. But here are some YouTube videos of that presentation from a user perspective I guess.

update...found the SketchFlow video!!! http://videos.visitmix.com/MIX09/C01F
Great keynote from there too: http://videos.visitmix.com/MIX09/KEY01
I know this is an old question, but for others who find this via search, I personally love mocking my websites up with mind mapping tools. I've tried several but my favorite was MindNode for Mac and Xmind for Windows.
XMind free download:
http://www.xmind.net/
MindNode free download:
https://mindnode.com/
I've also tried MindMeister which works just as well as other mind mapping tools and is hosted for you so you can access your mind maps anywhere. However, MindMeister only allows you three maps (currently) without upgrading to a paid subscription.
Another that I've worked with is mockflow.com which is great for mocking up websites with all their features and buttons and even making clickable navigation. They have a free version, but again it's very limited without upgrading to a paid version.
I'm using Slickplan. This cloud based app allows me to have access to my projects from different machines regardless of their operating systems. All I need is one of the leading web browsers (Chrome, Firefox, Safari).
With Slickplan you can create visual sitemaps from scratch or you can use Site Crawler to import your existing website to visualize and reorganize its structure.
Of course you can always export your projects to the XML format, and use the exported file to create pages and menu systems inside some popular content management system - Slickplan provides plugins for WordPress, Joomla, concrete5 and a few more.
