We are upgrading our project to 4D v12 and our QPix plugin stopped showing us a preview of the image we are about to take. The image capture works just fine; the only problem is that the preview simply shows a white screen.
If I select the "Video Settings..." button I get a screen with a preview, so I know that it should be possible to get the preview.
This is a longshot; if you need any more information I can provide it.
I heard back from Escape Tech Support and they claim that the issue is a bug in 4D v12. They are hoping for a fix in 4D v12.1.
MrHen, I'm glad you got an answer, even if it isn't a very satisfying on. Just so you know there isn't much in the way of 4D activity on SO (and most of what there is is for an unrelated application). If you have other issues I'd recommend the NUG or the official 4D forums.
4D NUG (networked users group) mailing list:
You can search it here: kb.4d.com
Join it (4D Tech) here so you can post: lists.4d.com/mailman/listinfo/4d_tech
Official 4D forums:
www.4d.com/us/community/forum.html
the NUG is little outdated, http://forums.4d.fr, is the place to go. There you can get in touch with the 4D headquarter instead with marketing on the NUG. :)

I am developing an application using 4D as front-end and postgresql as back-end. So i don't want the help menu to be displayed at front-end side. I do some research but i don't find any 4D commands to do so.
Also i went through 4D manuals which states that:
4D automatically manages the Help and application system menus.
These menus cannot be modified, except for the About 4D command,
which can be managed using the SET ABOUT command.
Is it really not possible or am i missing something?
Thanks in advance.
I think you are correct. You cannot remove the Help menu or set any of its items aside from 'About'.
You can go through the components and plugins you may be using and remove any of the help files within them so that they don't show up on the menu.
That is about as good a solution as we've come up with.
I am developing an application in which i need to create the video from the images. Currently i am doing this with java JMF. I then need to upload the video to the vimeo using the vimeo api.
So, if anyone can share the info that,
"Does vimeo provide the service/api of creating the video from the given images?"
If yes, pls provide some helpful link to know more about it.
Thanks in advance.
No, it does not. You should use something like QuickTime Pro, or istopmotion.
Vimeo does provide an API
https://developer.vimeo.com/api
As of July 17 2014
http://vimeoapi.tumblr.com/tagged/vimeo-api
But it doesn't appear to have the functionality you want. At least I couldn't find it with a cursory search. In fact it looks very primitive.
You should consider using some other piece of software for converting images to video, then uploading that.
Does anybody know anything about chrome.experimental.sidebar namespace? Is it still available? Is it going to be removed? Anything?
It's not available in the Google Chrome Extensions documentation anymore.
Do you know anything about availability of sidebars in Google Chrome?
You can see all relevant information in the corresponding Chrome bug. To quote comment 41:
The sidebar's on ice for now. We're going to go through an API
prioritization exercise near the end of the year to figure out what's
important for 2012, so there's some chance it could resurface. I'd put
the probability pretty low though.
And comment 42 clarifies that a sidebar API doesn't seem to be the top priority right now but it might still get finished later. Or, what sounds more likely judging by comment 50, this functionality will be morphed into a more generic API.
I happend to stumble upon this site
http://www.htmlfivewow.com/demos/terminal/terminal.html
It is simply amazing. I was just wondering on how is the terminal being emulated in the browser ? Can we embed the terminal in the browser and use it normally ? If so how?
i found this link which kinda enlightens the architecture http://www.htmlfivewow.com/slide33
But one thing aint clear what exactly is CRX-LEss Web app ? its completly new term , i havent herd of it before ( googling dint quite help me )
The actual presentation for the demos is from the Google I/O conference, and the talk was called HTML5: The Wow and the How. If you watch the video, they go over everything that's implemented in the terminal demo:
http://www.youtube.com/watch?v=WlwY6_W4VG8
It's very cool stuff.
A great thing about the web is that on any page you can View Source. Give it a shot. The source is well-structured and though it could be better-commented it's pretty straightforward. Even if you don't understand it in its entirety it will give you a place to start searching for the techniques used.
With JavaScript, the DOM, and <canvas> (which, I should mention, isn't used in this instance) just about anything can be created, from terminal emulators to Nintendo emulators.
A CRX-Less web app is an unzipped Chrome extension and points to the manifest.json file for the extension. It is an experimental feature and must be enabled in the chrome:flags page. https://developers.google.com/chrome/apps/docs/no_crx explains how the process works.
I imagine there must be out there a website that collects information about HTML 5 feature and what browsers version started to support them.
This might be a good way to decide based on your website profile, if you can apply that HTML 5 feature without a fallback for your visitors.
Do you know such a site/resource ?
For example I want to know what browsers support the multiple upload feature for inputs and what browser version was the first.
Update
I'm not pleased with the sites suggested so I'm opening a bounty.
Suggestions so far: Html5Test, Caniuse, modernizr.com, QuirksMode
Update 2
Some people don't understand the question. I need to implement the multiple upload feature. I know from analytics what browser are they using ( I know this is not 100% correct ).
I'm willing to sacrifice some of the visitors by not offering some advance features but I need to understand how big is this procent. I'm NOT trying to DETECT in anyway the browser. It's a similar approach with other sites that dropped IE 6 support.
So please don't talk about bad practice.
Try to look at Html5Test or caniuse.
If it's server side, you can analyze user agent to find out if client's version supports HTML5. Wikipedia is your friend.
If it's client side, there's Modernizr library.
A quick search gave me this interesting result (reproduced in several blogs): http://www.findmebyip.com/litmus/
And you can may also want to take a look at this list of how to detect each feature: http://diveintohtml5.ep.io/everything.html
Here is another website, quite incomplete but verbose and "work in progress" as of March 2011, so it might be worth keeping an eye on: http://html5accessibility.com/
This one is off topic, but since I found it, I add it. CSS compatibility in IE browsers (very extensive): http://msdn.microsoft.com/en-us/library/cc351024(VS.85).aspx
And here you can find info specific to the gecko engine: https://developer.mozilla.org/en/HTML/HTML5
And, of course, MDC has compatibility tables for each feature, but separated in different pages, not as a table, e.g.: https://developer.mozilla.org/en/HTML/Element/input
http://www.modernizr.com/
HTML5Test.com collects the information but they don't give detailed reports for perusal.
A good reference site for some stuff is http://www.browserscope.org/ but that doesn't go into a lot of detail with HTML5 specific support
Another source of related stuff is http://w3c-test.org/html/tests/reporting/report.htm which is creating a set of HTML testing tools that can be run.
You or someone who wanted to create this information could use these tests and then store the UA String of each browser that hit the site with the results of each test.
Then you could just find the earliest version of each browser type that a feature successfully run on.
I think this information is stored in the databases of the sites mentioned but they just don't display it which sort of sucks. Maybe try emailing them and suggesting they add these reports.
Take a look at caniuse.com, it’s exactly what you are searching for.
QuirksMode is also a great resource, and there is an entry for multiple files input.
My vote is for:
http://www.findmebyip.com/litmus
Which i found via this blog:
http://www.deepbluesky.com/blog/-/browser-support-for-css3-and-html5_72/
You should try this website. I hope this is what you were looking for.
