Throw exception and expect the user to catch it? Thanks

• ListItemCollection is limited to 127 items?

  - by HeavyWave

  I am trying to add a lot of item to ListItemCollection in the ListControl, but once the Count reaches 127 I can't add any more items. It doesn't throw any exceptions, just doesn't add the items. I have changed Capacity to 256, but it still won't add more than 127 items. Is there a hard-coded limit?

• How to define custom exception class in Java, the easiest way?

  - by yegor256

  I'm trying to define my own exception class the easiest way, and this is what I'm getting: public class MyException extends Exception {} public class Foo { public bar() throws MyException { throw new MyException("try again please"); } } This is what Java compiler says: cannot find symbol: constructor MyException(java.lang.String) I had a feeling that this constructor has to be inherited from java.lang.Exception, isn't it?

• How can I tell the number of replacements in a formatter string?

  - by sdanna

  Given the following method: (real method has a few more parameters, but the important ones are below...) public string DoSomething(string formatter, params string[] values) { // Do something eventually involving a call to String.Format(formatter, values); } Is there a way to tell if my values array has enough objects in it to cover the formatter, so that I can throw an exception if there aren't (short of doing the string.Format; that isn't an option until the end due to some lambda conversions)?

• How can I determine if a composite format string is invalid?

  - by Tinister

  Per the documentation, String.Format will throw a FormatException if either (A) the format string is invalid or (B) the format string contains an index that cannot be found in the args array. I want to be able to determine which (if either) of those conditions fail on any arbitrary string and array of arguments. Is there anything that can do that for me? Thanks!

• How to access a superclass method from a nested class?

  - by m01

  I hope this code explains the problem: class Foo { void a() { / *stuff */ } } class Bar extends Foo { void a() { throw new Exception("This is not allowed for Bar"); } class Baz { void blah() { // how to access Foo.a from here? } } } I know that I may be doing something wrong, because inheritance perhaps shouldn't be used in such way. But it's the easiest way in my situation. And, beside that, I'm just curious. Is it possible?

• Can @Inject be made option in JSR 330 (like @Autowire(required=false)?

  - by Eric B.

  Spring's @Autowire can be configured such that Spring will throw an error if no matching autowire candidates are found: @Autowire(required=false) Is there an equivalent JSR-330 annotation? @Inject always fails if there is no matching candidate. Is there any way I can use @Inject but not have the framework fail if no matching types are found? I haven't been able to find any documentation to that extent.

• Blackberry persistance: ObjectGroup createGroup vs. createGroupIgnoreTooBig

  - by Tamar

  What is the difference between the createGroup and createGroupIgnoreTooBig? I understand that createGroup will throw the too big exception when the object exceeds 64k, and createGroupIgnoreTooBig will not. But does it mean that createGroupIgnoreTooBig allows me to create objects larger than 64k, or will it only partially group it?

  - by HMojtaba

  Hi every one! I really need to make this connection throw wireless (or lan ethernet).

Is there any header or any library which can do that for me? thanks

• C# WPF XAML Loading

  - by user3713589

  Hi I'd like to inquire on how i can load a WPF Xaml into code so that I can change the values of the attributes of some XAML elements and output it by creating another XAML files. This is so that I can output the same file with values dynamically input by the user. the XamlReader.Load() method cannot be used; it will throw an exception (because they are unable to recognise Window as the root element). I'm using VS2013 and C#.

• DBTransaction Rollback throws

  - by pdiddy

  Looking into the documentation it says that the Rollback method can throw when the transaction is not in pending state (after begin transaction and before commit transaction). I can't seem to find a way to check whether the transaction can be rollback or not. There isn't a state property either.

• Safe division function

  - by bugspy.net

  I would like to define some kind of safe division (and modulo) function, one that would return some predefined value when attempting to divide by zero. I don't want to throw exceptions, just to return some "reasonable" value (1? 0?) and continue the program flow. Obviously there is no correct return value, but I wonder if there is some standard or known approach to this
