ios - How to delay the camera function that uses zxing library? -

-

I use zxing to scan the barcode but the camera scans the real quick, so that my method is overloaded with the result Lets do it. 

  - (empty) Capture result: (ZXCapture *) Capture Result: How to make it slow or delay the barcode to scan?  
 (ZXResult *) Result {If (! Result) Return; // We found a result display information about onscreen NSString * formatString = [self barcode formatattostring: result.barcodeFormat]; NSString * display = [NSString stringWithFormat: @ "Scan! \ N \ n Format:% @ \ n \ nContent: \ n% @", format string, result.txt]; [Self.decodedLabel DemonstrationOnMineTrade: @Selector (with Settext Object): Wait until Available: Yes]; // Vibrate Audio Services Play System Sound (CascismSIDID_Wibet); }    
 
 
 I suggest using the sleep function to use sleep (TimeInSeconds) Try to do this, so it will delay the scanner for the seconds you enter.

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...
