kandi X-RAY | QRCodeGenerator Summary
QR code (Quick Response Code) is the trademark for a type of matrix barcode (or two-dimensional barcode) first designed for the automotive industry in Japan. A barcode is a machine-readable optical label that contains information about the item to which it is attached. A QR code uses four standardized encoding modes (numeric, alphanumeric, byte / binary, and kanji) to efficiently store data; extensions may also be used. Read more(Wikipedia) . The QR Generator app is purely built in Java SE for backend and Java Swing for the UI, using the Model View Controller approach. It relies on XZing Library to build the QR and generate the 2D code image that can be exported to the local file system. To read the QR image, you will need to a QR Scanner or the many apps that can scan QR codes using mobile phone camera. Below is a typical screen of the application running, with the custom color scheme drop-down active in Windows 7. The L&F may differ depending on how your OS renders the UI components, since the application uses the System Default Look & Feel. A JRE 1.6 or later is required to run the application. Download the zip and unzip dist folder to a convinient folder. Ensure tha the following directories are present in the dist folder :- codes, icons, dist. These (folders)files are neccessary for the app to run. If everyting is okay double clicking on the .jar file will launch the application. Enjoy.

Answered 2021-Jun-01 at 18:56The base64 value you provided in your question is malformed, my recommendation is to not use Json Serialization for this Api response effort.
Try using Convert.ToBase64String
- Ensure the method returns

I have downloaded the QRCoder sources and I have compiled the sources with Visual studio 2019. Then I add a reference on my Visual stuio 2008 project to the generated QRCODER.dll from the folder "net35".

Answered 2021-Apr-27 at 10:40Does support the framework.net 3.5 default value in the method
The .NET Framework supports optional parameters in version 3.5 (in terms of the attributes being part of the framework), but the C# 3 compiler (which is what Visual Studio 2008 uses) doesn't. Optional parameters and named arguments were introduced in C# 4.
I would strongly recommend using a modern version of Visual Studio, even if you still need to target ancient versions of .NET. (I'd also strongly recommend moving off unsupported versions of .NET if at all possible.)

QUESTION
I am currently generating a QR code image for records in a table through a button click function, and then the image generated would need to be saved into the table.
But I am only able to generate the QR code image only and I can't seem to store the image into the database. The error given to me is:
Implicit conversion from data type nvarchar to varbinary(max) is not allowed. Use the CONVERT function to run this query.
I have search various methods online yet I can't seem to understand how the CONVERT function actually works. Below is my code:
...ANSWER
Answered 2021-Mar-01 at 04:39Instead of posting an object to the database, which is being sent as a string of some kind, you need to actually send the bytes.
Also it's a good idea to define the parameter with an explicit data type to avoid C# guessing (incorrectly) at your required data type as it has done to you here.

The attached program doesn't change the QR code in the QRView when the user changes the url in the TextField, yet the Text view below the QR code does update. What am I missing?
I tried this without the text field and also added/substituted a MapView to see if a different representable view would fire. The MapView didn't fire either and removing the Text view didn't change anything.

Answered 2020-Oct-05 at 08:45A background (hosted) service is a completely different service, using its own thread to do its job. You can't have your controller "run" something on that service, you have to tell it what to do, and have it do it.
The Background tasks with hosted services section in the docs shows two different ways a long running background service can work :
- A timed service can run each time a timer fires and do a periodic job, as long as the application is running
- A queued service waits for messages in a queue and performs a job when a message arrives
Sending an email fits into the second case. You could use the documentation example almost as-is. You can create an IBackgroundTaskQueue
interface that clients like your controller can use to submit jobs to run in the background:
