  • .split("1px") into ["1px",1,"px"] in Javascript

    - by Jay
    I'm rubbish at Regular Expressions, really! What I'd like is to split a string containing a CCS property value into an array of [string,value,unit]. For example: if I supplied the .split() method with 1px it'd return ["1px",1,"px"]. If I were to supply, similarly, 10% it'd return ["10%",10,"%"]. Can this be done? I appreciate all your help!

  • Using `g_object_set_data` for passing user name.

    - by PP
    I am using g_object_set_data to set user name with event_box so in call back i can get it with in event_box pointer. g_object_set_data(G_OBJECT(event_box), "user_name", (gpointer)(user_name) ); but problem is that i am setting user_name which is not an pointer allocated string. It is an local string (not allocated on hip) which gets destroyed. So is it necessary to allocated and then use the pointer, i just want to associate one name with this event_box.

  • In the Enterprise Library, how does the abstract Validator.cs have a method definition?

    - by Soham
    Consider this piece of code: public abstract class Validator { protected Validator() { } protected abstract void ValidateCore(object instance, string value, IList<ValidationResult> results); public void Validate(object instance, string value, IList<ValidationResult> results) { if (null == instance) throw new ArgumentNullException("instance"); if (null == results) throw new ArgumentNullException("results"); ValidateCore(instance, value, results); } } Look at the Validate() overload, how can an abstract class have definitions like this?

  • How is the result of openssl_sign() encoded?

    - by Bozho
    The docs about openssl_sign() say that the signature is returned in the passed string argument. My question is - how is it encoded? Base64, Hex-string, anything else? I don't have php installed and I have to use this PHP code I was given simply in order to verify whether my Java implementation is correct, so don't ask me "have you tried it" ;)

  • Python: Sort a dictionary by value

    - by the empirical programmer
    I have a dictionary of values read from 2 fields in a database: a string field and a numeric field. The string field is unique so that is the key of the dictionary. I can sort on the keys, but how can I sort based on the values? Note: I have read this post 72899 and probably could change my code to have a list of dictionaries but since I do not really need a list of dictionaries I wanted to know if there a simpler solution.

  • Why does Convert.ToBoolean("0") fail?

    - by JL
    I know that trying to convert string "0" to boolean will fail, I also know how to fix this, thanks to Jon Skeets answers on other questions. What I would like to know is WHY does C# not recognize "0" as a valid input for a boolean conversion, surely you could look at it like 0 = false, 1 = true, or even -1 = false and 0 = true, anyways, my logic tells me that it could be a valid input, so is there a very good reason why its not? My bet is old vb6 would be able to recognize the string input "0" as valid.

  • Why can't I construct an std::istream_iterator with an unnamed temporary?

    - by Stumped6789
    g++ allows this construction of an istream_iterator from an ifstream instance: std::ifstream ifstr("test.txt"); std::istream_iterator<std::string> iter1(ifstr); ...but it doesn't allow the same construction with an unnamed temporary: std::istream_iterator<std::string> iter2(std::ifstream("test.txt")); This gives: error: no matching function for call to ‘std::istream_iterator, ptrdiff_t::istream_iterator(std::ifstream)’ Does anyone know why this doesn't work? - thanks!

  • SQLite FTS3 sumulate LIKE somestrin%

    - by alex
    I'm writing a dictionary app and need to do the usual word suggesting while typing. LIKE somestrin% is rather slow (~1300ms on a ~100k row table) so I've turned to FTS3. Problem is, I haven't found a sane way to search from the beginning of a string. Now I'm performing a query like SELECT word, offsets(entries) FROM entries WHERE word MATCH '"chicken *"'; , then parse the offsets string in code. Are there any better options?
