C++ - Specialize member function for Template Class -

-

I have a class-template representing the mathematical vector: 

  Lt; class Value_T, unsigned int N & gt; Square vector (public: zero normal) () {// normal liver only to double / float vectors} Personal: vector value_type elements [n] in element:; // Number of elements fixed constant size = N; };   
 I have to make a special treatment for the whole type of vectors because vector generalization is not possible on this type. So I can have a separate (specialization) for the generalized method which is based on the template graph VectorT class-template's Value_T  
 I have tried to use the template specialization in different ways, But it did not get to work. Do I have to work a template function normally? At the moment it is just an  normal  member-method.   
 
 
 You can solve this with an  tag sending  technique:  
  #include & lt; Iostream & gt; # Include & lt; Type_traits & gt; Template & lt; Class Value_T, unsigned int N & gt; Square vector {public: zero normal () {tag = std :: integral_constant & lt; bool, std :: is_same & lt; Value_T, double & gt; :: using value || Std :: is_same & lt; Value_T, float & gt; :: value & gt ;; // Generally normalize only double / float vectors (tag); } Private: zero generalized (standard :: true_type) {std :: cout & lt; & Lt; "Generalized" & lt; & Lt; Std :: endl; } Zero general (std :: false_type) {std :: cout & lt; & Lt; "Not normal" & lt; & Lt; Std :: endl; } // Vector value element in element [n] in meteite elements; // Number of elements fixed static std :: size_t size = N; };

php - PDO bindParam() fatal error -

I am trying to learn PDO, now I have written this small code, but it gives me a serious error: Fatal error: Call a member function at a non-object dot () ... $ con = new mysqli ("127.0.0.1", "root", "", "csvdangercheck"); $ Query = $ con- & gt; ("Id,` var1`, `var2`) values ​​(" id,: var1,: var2) ";); $ query- & gt; bypass pattern (': id', $ id); $ query- & gt; BindParam (': var1', $ VAL1); $ Query- & gt; bindParam (': var2', $ val2); $ Query-> Executed (); I Trying to use print_r ($ con-> errorInfo ()) but Fatal error: Undefined method mysqli :: errorInfo ( ) ... can someone tell me what am I missing? Flaffeh said, you have PDO Missing Mysqy, try it: $ con = new PDO ('mysql: host = 127.0.0.1; dbname = csvdangercheck', 'root', '');

php - How can I cram 6+31 numeric characters into 22 alphanumeric characters? -

-
I have a 6 digit number and a 31-digit number (such as "234536" and "201103231043330478311223582826") that I The API needs to be crawled in the same 22-character alphanumeric field that uses PHP. I tried to convert each one to 32 (using custom code could not handle the base_convert () large number) and to connect with a single-character delimiter, but It only gives me 26 characters This is a restore API, so the letters should be URI-protected. I would like to do a database table cross with two references without reference to another reference value, if possible, any suggestions? Instead use a radix of 62. This will give you 22 characters for the top, 3.35 for the pre and 17.3 for the next. & gt; & Gt; & Gt; Math.log (10 ** 6) /math.log (62) 3.3474826039165504 & gt; & Gt; & Gt; Math.log (10 ** 31) /math.log (62) 17.295326786902177

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i...
