  • number of months between two dates - using boost's date

    - by MartinP
    I've used boost::gregorian::date a bit now. I can see that there are the related months & years & weeks duration types. I can see how to use known durations to advance a given date. Qu: But how can I get the difference between two dates in months (or years or weeks) ? I was hoping to find a function like: template<typename DURATION> DURATION date_diff<DURATION>(const date& d1,const date& d2); There would need to be some handling of rounding too.

  • Dreamweaver regular expression substitution followed by number

    - by mark
    Hi. I'm using Dreamweaver to update copyright dates across my site. I want to preserve the existing spacing (or lack thereof) between years. Examples: © 2002-2008 should update to © 2002-2009 © 2003 - 2008 should update to © 2003 - 2009 This is the regular expression I'm using to accomplish this in Dreamweaver's find & replace function Find: ©\s*(\d{4}\s*-\s*)\d{3}[^9] Replace: © $1 2009 Here's the PROBLEM: This expression works, but has that that extra space between the hyphen and 2009. If I write the replace expression without the space, as © $12009 then dreamweaver looks for the 12,009th substitution in the find expression, and, not finding one, prints $12009. Any ideas?

  • Best way to get a random number from 1 to 50 which ISN'T x

    - by Cocorico
    Hi guys! So this is probably programming 101 stuff, but I have a problem: I have 2 numbers which are between 0 and 49. Let's call them x and y. Now I want to get a couple of other numbers which are not x or y, but are also between 0 and 49 (I am using Objective C but this is more of a general theory question I think?). Method I thought of is: int a; int b; int c; do { a = arc4random() % 49; } while ((a == x) || (a == y)); do { b = arc4random() % 49; } while ((b == x) || (b == y) || (b == a)); do { c = arc4random() % 49; } while ((c == x) || (c == y) || (c == a) || (c == b)); But it seem kind of bad to me, I don't know, I am just trying to learn to be a better programmer, what would be the most elegant sweet way to do this for best practices? Thanks!

  • Regex to test if an input string contains a certain number of characters

    - by Dan
    So, I basically would like to test to see if a string contains a range of alphanumeric characters. It's to be used as a client-side validation and I don't want to prevent users from entering whatever they want. Best to give examples of what should/should not pass validation: So to be specific, the expression I'm looking for is to test to make sure string contains anywhere from 3 to 10 alphanumeric characters. I'd like to plug into an ASP.NET client side validator. NOTE: quotes not part of input (but could be!) " f o o " should pass since there are 3 chars "f_0_0" should pass " fo " should not "F......o......o......b.....a......r" should pass thx

  • Populating a Datagrid with variable number of columns and rows in Flex

    - by Rie Mino
    I am trying to figure out how to manage a Datagrid based on an XML object like this: <matrix rows="5" columns="5"> <column> <row>0.5</row> <row>0.21</row> </column> <column> <row>0.6</row> <row>0.9</row> </column> <column> <row>0.5</row> <row>0.5</row> </column> <column> <row>0.8</row> <row>0.4</row> </column> </matrix> I will need to populate the Datagrid column names based on a different XML object and use the above XML to populate each of the column's rows. I currently am able to create the Datagrid and populate its column headers but I am unsure as to how to how to add the rows for each column. The above XML will be update with new row and column elements added and deleted. This, of course, will be bound to the Datagrid to show updates. Thanks in advanced for your help.

  • C# Check for missing number in sequence

    - by Jon
    I have an List<int> which contains 1,2,4,7,9 for example. I have a range from 0 to 10. Is there a way to determine what numbers are missing in that sequence? I thought LINQ might provide an option but I can't see one In the real world my List could contain 100,000 items so performance is key

  • android Convert phone number in International Format

    - by Arutha
    I'd like to know whether it's possible to have phone numbers converted into international format when a call is outgoing. For instance, if a french user (sorry it's the only format i know i won't make a mistake :-) try to call with the national format : 01.47.12.34.56 then a method will convert it into international format like this : +33.1.47.12.34.56 I've looked into the doc of the PhoneNumberUtils but i don't know if there is a method doing what i want.

  • Single page app with high number of images working extremely slow on iOS8 safari/Webview

    - by NikhilWanpal
    We are working on a WebView (not WKWebView, yet) app, are are observing that the app runs extremely slow on iOS 8. The same app runs smooth on lower versions of OS like iOS7 and iOS6. So we tried it in safari on iOS8 and the performance is similar to iOS6 and 7. The app is filled with images and many are high resolution. While trying to trace the issue (trial and error!) we reduced the sizes and resolutions of the images and the performance improved, but it is still not at par with versions 6 and 7. We are unable to find any such issues reported elsewhere and are stuck. It would be great if we could get some pointers on this one.

  • Count the number of dates between two dates

    - by Matt Mitchell
    I'm looking to count the dates covered (inclusive) between two DateTimes (not .TotalDays) For example: 2012-2-1 14:00 to 2012-2-2 23:00 -> 2 2012-2-1 14:00 to 2012-2-2 10:00 -> 2 2012-2-1 14:00 to 2012-2-1 15:00 -> 1 2012-1-1 00:00 to 2012-12-31 23:59 -> 366 I can get this functionality with the code below: DateTime dt1 = new DateTime(2000,1,2,12,00,00); DateTime dt2 = new DateTime(2000,1,3,03,00,00); int count = 0; for (DateTime date = dt1; date.Date <= dt2.Date; date = date.AddDays(1)) count++; return count; Is there a better way?

  • Getting the number of posts a user has by the number of rows returned?

    - by transparent
    So I have a question. I have chatting/IM website that I am working on and I was making a user profile page. I wanted to show how many posts that user had. Another issue I had earlier was that when I called a certain value it would return a 'Resource #1' type string. But I got that working by using $totalposts=mysql_query("SELECT * FROM `posts` WHERE Username='" . $username . "'"); $totalposts = mysql_fetch_row($totalposts); $totalposts = $totalposts[0]; But that just returns the last postID of the most recent post. I thought that mysql_num_rows would work. But this code returns an error (example with numbers): 29: $totalposts=mysql_query("SELECT * FROM `posts` WHERE Username='" . $username . "'"); 30: $totalposts = mysql_num_rows($totalposts); 31: $totalposts =mysql_fetch_row($totalposts); 32: $totalposts = $totalposts[0]; That returns this error: Warning: mysql_fetch_row(): supplied argument is not a valid MySQL result resource in /home/a9091503/public_html/im/user.php on line 31 Thanks guys. :) I hope you can figure this out. :D

  • Large number of tables and Hibernate memory consumption

    - by Vedran
    I'm working on a large ERP project which has database model with about 2100 tables. With "only" 500 tables mapped with Hibernate, application deployed on the web server takes about 3GB of working memory. Is there any way to reduce Hibernate's metamodel memory footprint when using that many tables in one persistence unit? Or should I just give up on ORMs and go with plain old JDBC (or even jOOQ)? Right now I'm using Hibernate 4.1.8, Spring 3.1.3, JBoss AS 7.1 and working with MSSQL database. Edit: JavaMelody memory histogram output - with 2000 generated test tables that are a bit smaller in scope from the original db model (hence 'only' 1.3GB of spent memory)
