While designing a new WPF application I noticed exceptions not being thrown during data binding for controls with DataTemplates. To test I wrote the following simple user control with as little logic as possible. I'm using .NET 3.5 SP1, VS2008 SP1 running on WIN7. When the DataContext is set, TestMethod is called and an exception is t...
This fails on VS2010 RC LINQ-to-SQL with the InvalidOperationException "Stored procedures cannot be used inside queries.": var foo = (from a in aTable from b in this.SomeStoredProcedure() where a.Id == b.Id select b.Id); SomeStoredProcedure is a SQL procedure which returns a table. 'join' also appears to fail. Any thought...
Will the following append() in the catch cause the rethrown exception to see the effect of append() being called? try { mayThrowMyErr(); } catch (myErr &err) { err.append("Add to my message here"); throw; // Does the rethrow exception reflect the call to append()? } Similarly, if I rewrite it this way, will bit slicing occur if ...

I was playing around with istream iterators and exception handling a few days ago and I came across with this curiousity: #include <iostream> #include <fstream> #include <iterator> #include <algorithm> using namespace std; int main(int argc, char* argv[]) { if (argc < 2) { cout << argv[0] << " <file>" << endl; return -1...

In Java, is there a semantic difference between using "Illegal" (as in IllegalArgumentException) versus "Invalid" (as in javax.activity.InvalidActivityException)? During the course of an assignment it became useful to write a subclass of IllegalArgumentException to represent a series of input characters that cannot be tokenized, and I'...
I just want to confirm my understanding of exceptions and how they impact their objects. If I throw an exception, that halts the processing of a method, correct? So there's no point in doing if ( some_check() ) { throw new Exception(...); } else { ... } I should just do this if ( some_check() ) { throw new Exception(......

Is it a good idea to place these into their own subpackage below the package that has all the classes that will be using these exceptions? For example: com.company.project.core contains a bunch of classes which can throw some cus...
I'm using JPA in my DAOs outside of Spring . The Spring framework defines DataAccessExceptions that are independent of databases implementations. Is there any advantage for a non Spring user to use the Spring data access exceptions instead of those of JPA ? I guess that the Spring DataAccessExceptions exist since Spring handle several u...
