Today NetBalancer adds its most advanced feature ever since inception: Programmatic Rules.
A programmatic rule is a rule defined entirely in C# code, is compiled and then executed for every single network packet.
Based on the packet's properties and various environment data the rule then decides what priority, limit or block to assign to the packet.
Alternatively the rule can just pass the packet to the next rule if it doesn't match its criterias.
All the source code required to compile a programmatic rule in your preferred code editor is openly available in NetBalancer under an open source MIT license.
See the 'View embedding source code' link in the image above.
Just like C# scripts from the previous release, the rules also are not permitted any IO operation, including file, registry and network access to avoid elevation security vulnerabilities.
Code reflection is prohibited as well.
The license unlocks all NetBalancer App's and Service's functionality and provides:
The following code example sets event handlers for exceptions that occur on Windows Forms threads and exceptions that occur on other threads. It sets SetUnhandledExceptionMode so that all exceptions are handled by the application, regardless of the settings in the application's user configuration file. It uses the ThreadException event to handle UI thread exceptions, and the UnhandledException event to handle non-UI thread exceptions. Since UnhandledException cannot prevent an application from terminating, the example simply logs the error in the application event log before termination.
This event allows your Windows Forms application to handle otherwise unhandled exceptions that occur in Windows Forms threads. Attach your event handler to the ThreadException event to deal with these exceptions, which will leave your application in an unknown state. Where possible, exceptions should be handled by a structured exception handling block.
You can change whether this callback is used for unhandled Windows Forms thread exceptions by setting SetUnhandledExceptionMode. To catch exceptions that occur in threads not created and owned by Windows Forms, use the UnhandledException event handler.
This has been a long battle that will never end, hence the move to deliver software as services, i.e. online where the producer has more control over their content and can explicitly authorize and authenticate a user. In your case you want to do this offline. So in your scenario someone will attach your device to some system, and the accompanying software that you intend to write this routine on will make a check against the serial number of the device v/s user input.
N-based encoding (where N is the base of the number system) was often used to convert binary data into a human-readable text. The most commonly used inactivation key is base32. The advantage of this encoding is a large alphabet consisting of numbers and letters that case insensitive. The downside is that this encoding is not implemented in the .NET standard library and you should implement it yourself. You can also use the hex encoding and base64 built into mscorlib. In my example base32 is used, but I will not give its source code here. There are many examples of base32 implementation on this site.
By far the most secure way to do it is to have a centralized database of (serial number, activation key) pairs and have the user activate over the internet so you can check the key locally (on the server).
You want it to be easy to check, and hard to "go backwards". You'll see a lot of suggestions for using hashing functions, those functions are easy to go one way, but hard to go backwards. Previously, I phrased that as "it is easy to turn a cow into a hamburger, but hard to turn a hamburger into a cow". In this case, a device should know its own serial number and be able to "add" (or append) some secret (usually called "salt") to the serial and then hash or encrypt it.
If you are using reversible encryption, you want to add some sort of "check digit" to the serial numbers so that if someone does figure your encryption scheme out, there is another layer for them to figure out.
And you probably want to make things easier for your customers by making the encoding less likely to be messed up when the activation codes are handwritten (such as you write it down from the email then walk over to where the device is and punch the letters/digits in). In many fonts, I and 1, and 0 and O are similar enough that many encodings, such as your car's VIN do not use the letters i and o (and I remember older typewriters that lacked a key for the digit 1 because you were expected to use lowercase L). In such cases, Y, 4 and 7 can appear the same depending on some handwriting. So know your audience and what are their limits.
If your device has some secured memory which can not be read by connecting an programmator or an other device -you can store some key-code and then use any hashing algorithm like MD5 or SHA-1/2 to generate hash by:
This could be simplified by storing activation code itself if device has a secured memory onboard (like SmartCards has). In this way you can just keep own database of SerialCode - ActivationCode pairs.
Anything you do can be broken by a dedicated enough hacker. The question is not, "Can I create absolutely unbreakable security?" but "Can I create security good enough to protect against unskilled hackers and to make it not worth the effort for the skilled hackers?" If you reasonably expect to sell 10 million copies of your product, you'll be a big target and there may be lots of hackers out there who will try to break it. If you expect to sell a few hundred or maybe a few thousand copies, not so much.
I would look at the logs for SSRS on all of the machines as well as the load balancer. Check the SSRS logs and the windows event logs and might not even hurt to check the SQL Server logs. But I expect that one (or more) of the logs will provide better info than error 500. If memory serves, a 500 error is a server side error. Refreshing the page is likely pushing you over to a different server from the load balancer which is why a refresh fixes the issue. Basically, load balancer points you to server A which gives you the 500 error. You hit refresh, the load balancer gets your request and pushes you over to server B and you don't get the error. Since it is intermittent, it is likely that you are being directed to server A infrequently and thus don't see the error often.
But the logs will confirm what the issue is for sure. That and testing SSRS on each of the machines in the load balancer rotation. But even if you determine which machine in the load balancer rotation is giving the error, you will still need to check the logs to determine what is wrong. Therefore, I would check logs as my first step.
The above is all just my opinion on what you should do.
As with all advice you find on a random internet forum - you shouldn't blindly follow it. Always test on a test server to see if there is negative side effects before making changes to live!
I recommend you NEVER run "random code" you found online on any system you care about UNLESS you understand and can verify the code OR you don't care if the code trashes your system.
1. try to reconnect your WIFI, make sure your WIFI TCP/IP is using DHCP automatic obtain IP. if it is fixed IP, make sure the Fix IP is there that is not blank. (some user report this and be able fix the problem after reconnect to WIFI
Exactly Thank u, i dont know why they keep putting this comment when the problem 100% is from the last update just give us the older version until u fix the code and stop complaining about third party software the problem is from netcut i tried this version in 4 computers with different wifi and still the same no connection fix it and stop typing that the problem is from our computers thank u.

.NET Reactor is a powerful .NET code protection and licensing system that allows .NET software developers to protect their apps safely and easily. The program is very easy-to-use, clean, well organized, and intuitive interface, which assists developers in protecting their .NET software in a safe and simple way. .NET Reactor is able to generate a native exe file which cannot be understood directly as CIL, and the source is completely inaccessible. It is completely prevents any decompiling .NET assembly written in VB.NET, C#, J#, Delphi.NET, etc., by a variety of methods.
Leveraging the awesome WinDivert library, clumsy stops living network packets and capture them, lag/drop/tamper/.. the packets on demand, then send them away. Whether you want to track down weird bugs related to broken network, or evaluate your application on poor connections, clumsy will come in handy:
Here's a demo of clumsy working on a netcat listening for localhost udp packets, illustrated as animated gif.
