  • C#: How to replace "-" with " -" only when it's not preceded by "e"?

    - by MaDDoX
    I imagine I should use Regex for that but I still scratch my head a lot about it (and the only similar question I found wasn't exactly my case) so I decided to ask for help. This is the input and expected output: Input: "c-0.68219,-0.0478 -1.01455-0.0441 0.2321e-4,0.43212" Output:"c -0.68219,-0.0478 -1.01455 -0.0441 0.2321e-4,0.43212" Basically I need either commas or spaces as value separators, but I can't break the exponential index (e-4). Maybe do two successive replacements?

  • MySQL DATE_ADD usage, 5 day interval

    - by Webnet
    I'm trying to select the order total sum ($) and invoice count over a 5 day period in a single query. I can't seem to get this to happen though. The current query I have is here... SELECT COUNT(id) as invoice_count, SUM(orderTotal) as orders_sum, UNIX_TIMESTAMP(created) as created FROM ids_invoice WHERE DATE_ADD(created, INTERVAL +1 DAY) AND userId = '.$userId.$whereSql I'm not entirely sure DATE_ADD is the right function I'm looking for I'm fairly new to mysql date functions so perhaps I just missed the function I needed when going through mysql docs.

  • Are there “server-side comments” in JSF / Seam / RichFaces?

    - by Jonik
    With the JSF/Seam/RichFaces stack, is there a way to mark up comments (on XHTML pages) so that they will not be included in the HTML output? I.e., something like JSP's <%-- comments --%>, as opposed to normal <!-- comments -->. I heard that facelets.SKIP_COMMENTS context-param migth do this for normal HTML comments, but is there any other option? (After all, there might be some comments that you want included in the page output and some that you don't.)

  • Java writes bad wave files

    - by Cliff
    I'm writing out wave files in Java using AudioInputStream output = new AudioInputStream(new ByteArrayInputStream(rawPCMSamples), new AudioFormat(22000,16,1,true,false), rawPCMSamples.length) AudioSystem.write(output, AudioFileFormat.Type.WAVE, new FileOutputStream('somefile.wav')) And I get what appears to be corrupt wave files on OSX. They won't play from Finder however using the same code behind a servlet writing directly to the response stream and setting the Content-Type to audio/wave seems to play fine in quicktime. What gives?

  • When running UPDATE ... datetime = NOW(); will all rows updated have the same date/time?

    - by Darryl Hein
    When you run something similar to: UPDATE table SET datetime = NOW(); on a table with 1 000 000 000 records and the query takes 10 seconds to run, will all the rows have the exact same time (minutes and seconds) or will they have different times? In other words, will the time be when the query started or when each row is updated? I'm running MySQL, but I'm thinking this applies to all dbs.
