- If the question is inappropriate then click the 'vote to remove message' button
Insults, slap-downs and sarcasm aren't welcome. Let's work to help developers, not make them feel stupid..

For those new to message boards please try to follow a few simple rules when posting your question.- Choose the correct forum for your message. Posting a VB.NET question in the C++ forum will end in tears.
- Be specific! Don't ask "can someone send me the code to create an application that does 'X'. Pinpoint exactly what it is you need help with.
- Keep the subject line brief, but descriptive. eg "File Serialization problem"
- Keep the question as brief as possible. If you have to include code, include the smallest snippet of code you can.
- Be careful when including code that you haven't made a typo. Typing mistakes can become the focal point instead of the actual question you asked.
- Do not remove or empty a message if others have replied. Keep the thread intact and available for others to search and read. If your problem was answered then edit your message and add "[Solved]" to the subject line of the original post, and cast an approval vote to the one or several answers that really helped you.
- If you are posting source code with your question, place it inside <pre></pre> tags. We advise you also check the "Encode "<" (and other HTML) characters when pasting" checkbox before pasting anything inside the PRE block, and make sure "Use HTML in this post" check box is checked.
- Be courteous and DON'T SHOUT. Everyone here helps because they enjoy helping others, not because it's their job.
- Please do not post links to your question into an unrelated forum such as the lounge. It will be deleted. Likewise, do not post the same question in more than one forum.
- Do not be abusive, offensive, inappropriate or harass anyone on the boards. Doing so will get you kicked off and banned. Play nice.
- If you have a school or university assignment, assume that your teacher or lecturer is also reading these forums.
- No advertising or soliciting.
- We reserve the right to move your posts to a more appropriate forum or to delete anything deemed inappropriate or illegal.
cheers,

There is a requirement to send and receive data over TCP/IP with a Fiscal (tax) device which acts as a gateway to the Tax authority server.
The application runs on c#.
Can anyone suggest suitable c# libraries which can be used for this purpose?
The data is to be packaged in JSON format.
Any help would be very much appreciated.

Have you researched the API, and/or requirements/protocols/syntax/authorization, for interop with the specific device you describe ?

hello
have searched google a lot but couldn't find any.
i am trying to create a report in visual studio 2019. data is coming from SQL server and using reportViewer1 to print the report.
can someone show me a good tutorial on it.
|

The reportViewer control has print controls on it. Did you try those?
|
|

i can't get to show data in the report.
i even tried with report wizard too.
first created a dataset then in the dataset created data table.
after this report filed headers are added to the report and when i run report shows only header names but no data.

It's been a long time since I have used it so I don't remember any specifics but it sounds like either the sql is not being executed or it is and it's not returning data.
Try using Sql profiler on your database to see if any sql is being executed.

Hey,
The idea is very simple, as Blazor can run ether as a Webassembly or over SignalR, shouldn`t it be possible when using a SignalR connection, to mirror the whole website of a user?
Like for support purposes, to inject a support person directly into what the user is seeing by mirroring the connection and replay all actions from one user to the output of another one?

That's why I didn't add a report in S&A.

I like hacking. That's one of the best ways to learn how things work. Do you have a question?

Learning how to exploit a vulnerability teaches not how to code.
Been doing development for over 20 years, and a "little" paranoid. Sporting my own hostfile and delivering updates to multiple hosts.
I like education.

Sure it can.
Just like SQL injection. That's hacking but we talk about it all the time. Hacking is a good way to learn how things work.

No, it doesn't; it teaches nothing about patterns, not even about security, it only shows where breaches are.

Thank you for proving my point.

It's a way of learning to know about weaknesses, not about how things work. Here an analogy for ya; you claim you can run an atomic power plant, because you know an unguarded door. In my opinion, you not even less qualified than any real programmer, but a liability.
And you know you are; that's why I post under my real name, and you don't dare too.

I don't think you understand your point then.
If all we told people is to use parameterized queries but did not explain why, the lesson would not be learned as well. Explaining how non-parameterized queries can allow someone to hack your db is magnitudes more valuable than just telling them to use parameters.

1. You can't prove that it's your real name.
2. You can't prove this is not my real name.

I can, there's a photograph on here from me. Look it up. No, no record government linking me to that, I not that much of a fool.

Easy, that's not even a legal name; you're not allowed to name children like that.
I been a developer for over 20 years. Been concerned with security for the same time. We "know a bit" about the subject

I am so old that I find the very idea of SQL injection completely crazy. Why would anyone even get close to the idea of passing SQL code ahead, without parsing it and consider it against authorization restrictions?
I know. "Because it would reduce performance". So then you could make two versions of your SQL based application: One HighPeformance version to use when benchmarking or comparing against alternatives. When you boost multiplatform and high availability, there is another, "safe" version with all the flexibility and functionality ruining performance, but beneficial in a lot of other ways.
