INSERTED: Let’s look at “statistical significance”. Assume there’s a function call instruction somewhere. You can’t necessarily see it – a class, or a macro, or the compiler, may have slipped it in. There are other calls to the same function nearby, but this call is in a loop, or its arguments are such as to … Read more

For code in your project, the only way is adding a declaration saying that you expected that — possibly protected by an if False so that it doesn’t execute (the static code-analysis only sees what you see, not runtime info — if you opened that module yourself, you’d have no indication that main was expected). … Read more

You should suppress the warnings in this case. Code that deals with disposables should be consistent, and you shouldn’t have to care that other classes take ownership of the disposables you created and also call Dispose on them. [SuppressMessage(“Microsoft.Usage”, “CA2202:Do not dispose objects multiple times”)] public static byte[] Encrypt(string data, byte[] key, byte[] iv) { … Read more
You’re missing a return statement. When the compiler looks at your code, it’s sees a third path (the else you didn’t code for) that could occur but doesn’t return a value. Hence not all code paths return a value. For my suggested fix, I put a return after your loop ends. The other obvious spot … Read more
Python caches integers in the range [-5, 256], so integers in that range are usually but not always identical. What you see for 257 is the Python compiler optimizing identical literals when compiled in the same code object. When typing in the Python shell each line is a completely different statement, parsed and compiled separately, … Read more
I think you can just have an id that automatically increments and make it your primary id. Then, your checking should be to check the student number and syearid and status before allowing the student to vote. with that you can just have 1 table for the vote records.
