• Can I use Linq-to-xml to persist my object state without having to use/know Xpath & XSD Syntax?

  - by Greg

  Hi, Can I use Linq-to-xml to persist my object state without having to use/know Xpath & XSD Syntax? ie. really looking for simple but flexible way to persist a graph of object data (e.g. have say 2 or 3 classes with associations) - if Linq-to-xml were as simple as saying "persist this graph to XML", and then you could also query it via Linq, or load it into memory again/change/then re-save to the xml file.

• How can an object not be compared to null?

  - by ProfK

  I have an 'optional' parameter on a method that is a KeyValuePair. I wanted an overload that passes null to the core method for this parameter, but in the core method, when I want to check if the KeyValuePair is null, I get the following error: Operator '!=' cannot be applied to operands of type System.Collections.Generic.KeyValuePair<string,object>' and '<null>. How can I not be allowed to check if an object is null?

  - by WilliamKF

  I have an unsigned char array that I need in a std::string, but my current way uses reinterpret_cast which I would like to avoid. Is there a cleaner way to do this? unsigned char my_txt[] = { 0x52, 0x5f, 0x73, 0x68, 0x7e, 0x29, 0x33, 0x74, 0x74, 0x73, 0x72, 0x55 } unsigned int my_txt_len = 12; std::string my_std_string(reinterpret_cast<const char *>(my_txt), my_txt_len);

• How can I return a Future object with Spring without writing concurrency logic?

  - by Johan

  How can I return a java.util.concurrent.Future object with a Receipt object and only use the @javax.ejb.Asynchronous annotation? And do I need any extra configuration to let Spring handle ejb annotations? I don't want to write any concurrency logic myself. Here's my attempt that doesn't work: @Asynchronous public Future<Receipt> execute(Job job) { Receipt receipt = timeConsumingWork(job); return receipt; }

• How do I create a duplicate instance of object contained in a shared pointer in c++?

  - by user367848

  I have an object which has both a copy constructor and assignment operator defined. It is enclosed inside a shared pointer. I want to make another shared pointer that contains a copy of the original shared pointer (i.e. new shared pointer to a new memory location, which however, has the same data as the original object). Thanks for any assistance.

• How to remove a single, specific object from a ConcurrentBag<>?

  - by routeNpingme

  With the new ConcurrentBag<T> in .NET 4, how do you remove a certain, specific object from it when only TryTake() and TryPeek() are available? I'm thinking of using TryTake() and then just adding the resulting object back into the list if I don't want to remove it, but I feel like I might be missing something. Is this the correct way?

• How to assign a value of a property to a var ONLY if the object isn't null

  - by Blankman

  In my code, is there a shorthand that I can use to assign a variable the value of a object's property ONLY if the object isn't null? string username = SomeUserObject.Username; // fails if null I know I can do a check like if(SomeUserObject != null) but I think I saw a shorthand for this kind of test. I tried: string username = SomeUserObject ?? "" : SomeUserObject.Username; But that doesn't work.

• Is there a standard dialog for constructing an ADO.Net connection string (that is redistributable)?

  - by rathkopf

  I want to use a standard dialog to solicit user input of an ADO.net connection string. It is trivial to do for the oledb connection string as described here: MSDN Article on MSDASC.DataLinks().Prompt I've also found examples that use Microsoft.Data.ConnectionUI.dll and MicrosoftData.ConnectionUI.Dialog.dll from VS (HOWTO: Using the Choose Data Source dialog of Visual Studio 2005 from your own code). Unfortunately these DLLs are not licensed for redistribution. Is there a standard dialog for choosing a data source that can be distributed with my application?

• How do I translate a ISO 8601 datetime string into a Python datetime object?

  - by Andrey Fedorov

  I'm getting a datetime string in a format like "2009-05-28T16:15:00" (this is ISO 8601, I believe) one hack-ish option seems to be to parse the string using time.strptime and passing the first 6 elements of the touple into the datetime constructor, like: datetime.datetime(*time.strptime("2007-03-04T21:08:12", "%Y-%m-%dT%H:%M:%S")[:6]) I haven't been able to find a "cleaner" way of doing this, is there one?

• Best way to manage JSON object via GET and POST in php.

  - by Kucebe

  My site does some short ajax call in JSON format, using jQuery. At client-side i'd like to send object just passing it in ajax function, without being forced to wrap it in an object literal like this: {'JSON_Obj' : myJSON_Obj }. For the same reasons, at server-side i'd like to manage objects without the binding of $_GET['JSON_Obj'] or $_POST['JSON_Obj']. For example, using file_get_contents("php://input"), i can manage POST requests in that way, but in GET format it doesn't work. Any suggestions?

• What does a b prefix before a python string means ?

  - by kriss

  In a python source code I stumbled upon I've seen a small b before a string like in: b"abcdef" I know of u prefix that means unicode and r prefix that means raw. What does the b stand for and in which kind of source code is it useful as it seems to be exactly like a plain string without any prefix ?

• Why is "int + string" possible in statically-typed C# but not in dynamically-typed Python?

  - by Salvador Dali

  While studying C# I found it really strange, that dynamically typed Python will rise an error in the following code: i = 5 print i + " " whereas statically typed C# will normally proceed the similar code: int i = 5; Console.Write(i + " "); I would expect other way around (in python I would be able to do this without any casting, but C# would require me to cast int to string or string to int). Just to highlight, I am not asking what language is better, I am curious what was the reason behind implementing the language this way.
