General concept is that when a function (or method) has multi return values one being an error, error should be checked first and only proceed if the error is nil. Functions should return zero values for other (non-error) values if there is an error. If the function behaves differently, it should be documented. http.Get() does … Read more
I have found that most of the time, the reccomended fix is to add (on error resume next) before setting the shape, as I get an error saying it does not exist. NO! The recommended way to handle runtime errors is not to shove them under the carpet and continue execution as if nothing happened … Read more
Since I’ve had a little bit of a struggle with the two existing answers, I’d like to share the solution I ended up with. First of all I created my own version of an ErrorListener like Sam Harwell suggested: public class ThrowingErrorListener extends BaseErrorListener { public static final ThrowingErrorListener INSTANCE = new ThrowingErrorListener(); @Override public … Read more
Reading these answers, I find it very unhelpful to say, “Exceptions should only be used for exceptional conditions”. This begs the whole question of what is an “exceptional condition”. This is a subjective term, the best definition of which is “any condition that your normal logic flow doesn’t deal with”. In other words, an exceptional … Read more
Rust generally solves errors in two ways: Unrecoverable errors. Once you panic!, that’s it. Your program or thread aborts because it encounters something it can’t solve and its invariants have been violated. E.g. if you find invalid sequences in what should be a UTF-8 string. Recoverable errors. Also called failures in some documentation. Instead of … Read more
Assuming no UB, are 5 of the 8 possible and not the 3 unexpected ones? especially is valid input possible with error indicator set? Speaking specifically to the provisions of the standard, I’m inclined to agree with your analysis: Few functions are specified to clear the error indicator of a stream, and fgetc() is not … Read more
I like to start by categorize the possible errors. Categorize the errors. Page Not Found (this is full my log). Breaking parameters of the page by trying to hack it Error from wrong user data input. Totally Unknown error – a new bug that we must fix. a Very hard General error – nothing runs … Read more
There is still a problem in your “solved” code. You should check for fail() before checking the values. (And obviously, there is the problem of eof() and IO failure as opposed to format problems). Idiomatic reading is if (cin >> choice) { // read succeeded } else if (cin.bad()) { // IO error } else … Read more
In playing around with the procedure, I can get a a return -6, if I insert a null into foo.KeyCol and remove the RAISERROR in the inner catch. This is something SQL Server is doing, and is documented here: Return Values from Stored Procedures.
As dbaseman states this is because the asp.net handlers are not called for non-asp.net files. An easy way to force the asp.net handler to operate on all requests is to set the following in your web.config. <system.webServer> <modules runAllManagedModulesForAllRequests=”true”> </system.webServer> This tells IIS to run through all of the managed modules for all requests such … Read more
