java - The value of the local variable word is not used -

-

I have a way in which a scanner is in the form of a parameter, the purpose of the method is to calculate the number of words in a file Do it and have to return that number. Here's the method: 

  Public Static Inter WordCount (Scanner InputFile) FontNoteFound Actions {int wordCount = 0; While (inputFile.hasNext ()) {string word = inputFile.next (); Word count ++; } Return password; }   
 The method works fine, but I "do not use the value of the local variable" warning which I would like to get rid of I understand why I am getting a warning, however, as far as I know, I need  
  string word = inputFile.next ();   
 To move the pointer through the file. I can suppress the warning, though, I think that I am probably trying to do. I can use only the scanner class to read the file.   
 
 
 What you're doing is okay, but warnings are given because you only  the word < / Code> and can not read it anyway, instead of just saving the results, leaving the assignment and just try using  inputFile.next () .

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...
