My C# Winform application encounters the situation where it cannot access a disposed object. The disposed object is a form (frmQuiz) that is opened from a button on the login form. The Situation: My application typically has two or three forms open at the same time. The Program.cs file runs form frmLoginBackground, which is just a s...
Hi, What would a piece of code which "uses exceptions to control flow" look like? I've tried to find a direct C# example, but cannot. Why is it bad? Thanks ...
I have created a collision class to detect collisions using pixels. In my class I've also developed some functions for determining the collsion angle. Based on this I created some examples: http://megaswf.com/serve/25437/ http://megaswf.com/serve/25436/ (Space to change gravity, right/left to give some speed to the ball.) As you will...
I would like to write a test using simpleTest that would fail if the method I'm testing results in a PHP E_NOTICE "undefined index : foo". I tried expectError() and expectException() without success. The simpleTest webpage indicate that simpleTest isn't able to catch compile time PHP errors, but E_NOTICE seems to be a run time error. I...
I'm trying to catch an Exception when an invalid value gets stored into a DataRow. I'm reading the values from a text file so anything could be stored there. I was hoping to be able to catch an InvalidCastException from the following code... try { // Store the values into the Data Row DataRow row = dataset.Tables["Table"].NewRow()...

Hi, I removed some class file *.class from a java project. It aims to make the whole project folder clean. Since the project was compilable and running well, I suppose that it will run faster after I clear some *.class. However, I got exception java.lang.ClassNotFoundException: at java.net.URLClassLoader$1.run(URLClassLoader.java:...

Would you throw an IllegalStateException if: A method is unable to do its job because of the value(s) of one or more fields Those fields are final and assigned only in the constructor? Textbook example: your class is an immutable Collection<BigInteger> and your method is supposed to return the maximum element, but this instance is em...
hello. I have run into broken compiler, which does not allow exceptions to inherit from std::exception (nvcc 3.0). so had to create workaround: struct exception { explicit exception(const char* message) { what_ = message; } virtual const char *what() const throw() { return what_; } operator std::exception() con...
Just had an interesting problem, caused by the following sequence of events: Code called from a WPF OnRender override threw an exception (there's no mystery in this - it's a trivial bug in some viewmodel code) The exception was unhandled, so was picked-up by our DispatcherUnhandledException handler. The DispatchedUnhandledException han...

I'm converting a Java library to Objective-C. The Java code uses exceptions flagrantly (to my Objective-C accustomed mind). When converting, should I be throwing Objective-C exceptions (only within the library; I'll catch them before they leave) or should I use NSError constructs. I'm familiar with the use-case for exceptions in regular...
If a method fails to do what it says it will do (e.g. if SendEmail fails to send an email), it should throw an exception. I blogged about this in-depth (optional read): Do your work, or throw an exception - example. It seems this idea is already a convention, even though I have not found it described elsewhere. "Exceptions are for ex...
