I want to create a QR-code myself with a logo. Maybe its because I don't know enough about QR codes but I'm scared that if the generator where I created the QR-code gets removed that my QR-code isn't working anymore. So that's why I want to create it myself.
so my questions are as follows:
Is it convenient and possible to make a QR code with a logo from scratch without a generator?
Does anyone have a tutorial for this?
Do I not have to worry about using a generator because the QR code continues to work if the generator no longer exists?

We generate a QR code fine for TOTP multi factor. This QR code can be consumed fine by google authenticator, authy, etc.
We are trying to figure out how to include our logo, so the auth app can show our logo instead of a generic logo.
I have dug all over for the spec on what goes in the QR code, and have not found this info yet.
There is nothing in the spec for adding a logo.
Instead, what services like Authy and andOTP do is look at the provider, and pattern match against a known list of popular providers.
For example, andOTP has a curated list of thumbnails for specific services.
If your organisation is as big as, say, Dropbox - you'll already be on the list. If not, you'll need to ask Authy and all the other providers to add your logo.
This has nothing to do with TOTP at all.
As the data in any QR code is redundant, there are some techniques allowing adding a logo by sacrificing the redundancy. Your QR code will become less readable though

Although it's not part of the spec, some implementations (at least FreeOTP) allows you to specify a logo with the image parameter.
example:
otpauth://totp/Issuer%3Ajohn%40example.com?image=https://picsum.photos/100&secret=4ED3SSHWSYSHC3FTEZFIOFPLDFIT2R2Y&issuer=Issuer
Not all implementations take this into account. In fact I only now for sure it works with FreeOTP since 2014. I've not digged further on other implementation.
So, I need to create a photo gallery for a client. However, I do not have access to the code base yet (I know :/ ) and will not for a while. There's also nobody technical onsite, so they wouldn't be able to implement what I send them if I hand code the project. I was thinking of creating the gallery using something like WordPress/Tumblr/SquareSpace etc. and having them just link through their original site. I'm aware that there are a lot of issues concerning building this, but what do you think the best way to tackle this is?
I'm currently working on a project that requires me to generate a printable report. I'm using a PDF reporting I found in code project, you can click here: PDF Reporting to get a better view.
The thing is that the report that I need to produce already has a form that needs to be followed that can be found here: FORM. I was planning on placing the form as a background image through CSS3, place the necessary data over the image and throw it to the PDF reporting controller. Problem is that when the pdf view has been generated, the background image is missing. Is it possible to actually pass an image to this PDF reporting? I already tried placing an img tag as mentioned in the site but it didn't work.
Is this a good solution or is it better if we recreate the form from scratch. If you have other approach to this problem, I'd be glad to hear your suggestions.
Oh and by the way, we are using mvc3, razor view.
Update: We are also using entity frame work and asp.net 4.1
Thanks in advance!
I would suggest you to think about Microsoft Report Viewer.
You have a proper designer, very easy to use, and you can generate PDF files as well.
You can find a good tutorial here.
In your situation it would be better to map each field of the report as a parameter so you do not have to create a dataset.
We need to compile to QtHelp (.qch and .qhc). I'm wondering what tool/toolchain would be easiest for this? We'd like a WYSIWYG help authoring tool as our starting point, then run the output from that through whatever we have to to get QtHelp.
We have used Help & Manual in the past, and that's the kind of WYSIWYG interface we're looking for in a help authoring tool. But we need the toolchain to produce simple html pages (one per help topic) that we can use with qhelpgenerator or qcollectiongenerator, as well as create the .qhp's (at least the table of contents and the keywords sections) and .qhcp to generate the .qch's and .qhc. I'm not seeing how Help & Manual can fit into this.
We've looked briefly at Sphynx, but it seems it has extremely limited options for text formatting. For example, it doesn't look like there's any way to change the font, font size, font color, etc. for a section of text. It appears to be actually impossible to have text that is both bold and italic. Looks great for developer documentation, but seems to be missing basic stuff for authoring a user help file. Please correct me if I somehow missed the basic text formatting features!
So, what WYSIWYG help authoring tool do you recommend, and what is the path from that tool to .qch's and a .qhc?
Looks like Help and Manual will work after all! Here's the sequence we're looking at now. If please comment if you see any problems or improvements that can be made.
In Help & Manual (tested with version 5.5.1 Build 1296 professional license), in the Project Explorer, in the Configuration section:
Go HTML Page Templates\Default. In the HTML Source Code tab, comment out the section.
Go to Publishing Options\Web Help.
In Layout, select No frames, no scripts.
In Navigation, we don't need anything checked - although if there is a way to control the format of the value of KEYWORD_INDEX so we could copy and paste directly into our .qhp, that would be great! I haven't found a way to do that, so we plan to maintain keywords directly in the .qhp.
Similarly, Table of Contents is also irrelevant, unless we can control the format we'll have to maintain the toc directly in the .qhp.
In Popup Topics, we are set to HTML encoded topics. Not sure if this is necessary.
That's all the settings we have to change. Create help content in H&M as normal, then to publish Webhelp. This creates a separate .htm file for each topic.
In the same folder as the .htm's, we create our .qhp and .qhcp files, and run qcollectiongenerator to produce our .qhc, which we then display with Qt Assistant. See http://doc.qt.nokia.com/4.7/qthelp-framework.html for help with the Qt side of this toolchain.
Again, it would be great if we could find a way to set up H&M to create the toc and the keywords in the format required for the .qhp and we could just paste them into the .qhp (or for that matter, maintain the .qhp in that template also). Another option would be to write a script to convert from what H&M creates for toc and keywords to what the .qhp requires. If you do that and don't mind sharing, please post the code!
Some benefits we find using H&M to solve this problem:
multiple documenters can work simultaneously, and source is stored as text files in Subversion, so it is versionable and you can compare changes.
easy WYSIWYG creation of help topics
can handle all kinds of text formatting and links. For example, in an end-to-end test of features to see what features of H&M would work in our end product (.qhc viewed in Qt Assistant), I was surprised to see Qt Assistant even handling hotspots in an image linking to other topics/anchors.
the .qhc is integrated into Qt so you have good control of your help from within your Qt app.
Again, if anyone has a better solution or improvements to this one, please post!
use Helpinator 3 Professional it's generat chm qt javahelp word pdf files easly ..
You might consider the HelpNDoc help authoring tool which has a WYSIWYG editor and can generate Qt Help files out of the box. Generated source files can optionally be kept for manual editing and manual compilation.
I want to embed live-graph.org jar into an applet and load via a webpage.
Can someone give me an example on how to call LiveGraph.application(); in an applet?
Thanks
So far I've been using the code given in following links. I'm not sure if I'm doing it right, so feel free to correct me.

I am making two another classes that are used in a livegraph demo. Actually I don't want to generate random numbers--right now I just want the application to run.
