  • How to pass non-fatal warnings from a library

    - by wRAR
    A library function parses a file and returns an object. If a parser encounters unknown data, missing values etc., it shouldn't throw an exception and stop parsing (because this is not fatal), but there should be a way to pass information about these things to a caller (so that warnings can be displayed in the UI, for example). How can these warning be returned? I'm thinking of passing a callback function/object into the library, are there any other possible solutions?

  • Using CompareTo() on different .NET types (e.g. int vs. double)

    - by Yossin
    Hi, I've got a static method that accepts two object type variables and runs the CompareTo() method: public static int Compare(Object objA, Object objB) { return (((IComparable)objA).CompareTo(objB)); } Problem is that CompareTo() throws an exception when trying to compare between different types (e.g. int and double). Does any one know of a better way in C#, to compare between two different types? Or a workaround to this problem? Thanks

  • How do I escape backslashes in JSON?

    - by peteb
    I am using Firefox's native JSON.parse() to parse some JSON strings that include regular expressions as values, for example: var test = JSON.parse('{"regex":"/\\d+/"}'); The '\d' in the above throws an exception with JSON.parse(), but works fine when I use eval (which is what I'm trying to avoid). What I want is to preserve the '\' in the regex - is there some other JSON-friendly way to escape it?

  • How do I set a resource file to non-embedded

    - by themaninthesuitcase
    In Visual studio 2008 is it possible to have a resource file that is included as a separate file after compilation rather than as an embedded resource. This is to enable small changes to be rolled out more easily. I have tried build options of Resource, None, Compile and also copy local on and off for most of these. However when ever I try access the resource at run time I get a cannot find resource exception. Is this actually possible or am I wasting my time?

  • How to stop attributes from being pickled in Python

    - by Ries
    I am using gnosis.xml.pickle to convert an object of my own class to xml. The object is initialized so that: self.logger = MyLogger() But when I do dump the object to a string I get an exception stating that the pickler encountered an unpickleable type . Is there a way to 'tag' the logger attribute so that pickler will know not to try and pickle that attribute?

I'm gonna show some code and ask, what could be optimized and where am I sucked? sublist([], []). sublist([H | Tail1], [H | Tail2]) :- sublist(Tail1, Tail2). sublist(H, [_ | Tail]) :- sublist(H, Tail). less(X, X, _). less(X, Z, RelationList) :- member([X,Z], RelationList). less(X, Z, RelationList) :- member([X,Y], RelationList), less(Y, Z, RelationList), \+less(Z, X, RelationList). lessList(X, LessList, RelationList) :- findall(Y, less(X, Y, RelationList), List), list_to_set(List, L), sort(L, LessList), !. list_mltpl(List1, List2, List) :- findall(X, ( member(X, List1), member(X, List2)), List). chain([_], _). chain([H,T | Tail], RelationList) :- less(H, T, RelationList), chain([T|Tail], RelationList), !. have_inf(X1, X2, RelationList) :- lessList(X1, X1_cone, RelationList), lessList(X2, X2_cone, RelationList), list_mltpl(X1_cone, X2_cone, Cone), chain(Cone, RelationList), !. relations(List, E) :- findall([X1,X2], (member(X1, E), member(X2, E), X1 =\= X2), Relations), sublist(List, Relations). semilattice(List, E) :- forall( (member(X1, E), member(X2, E), X1 < X2), have_inf(X1, X2, List) ). main(E) :- relations(X, E), semilattice(X, E).

  • Why doesn't HashTable.Contains() just simply return false if it is passed a null?

    - by Nate Pinchot
    I understand why passing a null to HashTable.Contains() doesn't work, but I don't understand what the point of it throwing an ArgumentNullException is - instead of just simply returning false? What is the benefit of throwing the exception (other than to make me do null checks before calling .Contains())? Caused By [System.ArgumentNullException] Key cannot be null. Parameter name: key at System.Collections.Hashtable.ContainsKey(Object key) at System.Collections.Hashtable.Contains(Object key)

  • Determining if an Activity exists on the current device?

    - by stormin986
    Is there a way to check and see if an Activity exists on your device? If I have a youtube video link I want to specify it open in the YouTube PlayerActivity. However, I don't want to crash if for some reason they don't have it. Is there a way to check and see if the activity exists? I don't think I can catch the runtime exception since startActivity() doesn't throw it.

  • unique selling points: php, flash, rails

    - by pwebdev
    on reflecting how to talk with prospect customers on technologies for web applications, what are important requirements for chosing a specific technology? I am biased towards ruby on rails, but the code base and community of PHP is larger, while the user experience of flash sites is often an advantage to the segment of higher paying customers. how would you argue for or against the usage of a technology in general? for ruby on rails in particular?

  • Are there any simple, stupid, module based, cross-platform, c++ projects that I can check out of a r

    - by leeand00
    I'm looking for one just to get a general idea of how a standard C++ project should be properly setup. (If that's possible... :-p) Here are my requirements for this project: module-based (has libraries/modules that compile into a main program module) compiles cross-platform I'd like to do this so that I can get a hold on the basics of how a good C++ project is setup, and so that I can test out Premake.
