  • R - Subsetting XTS via Time and Which

    - by user2844947
    Currently, I have a XTS, called Data, which contains a Date, and two value columns which are numbers. I would like to get a single number as output and which would be the mean of Value1 in the time period from a point where Value2 < mean(Value2) and going forward 14 data points, weeks in this particular data set. In order to get the dates where Value2 < mean(Value2), I wrote the below code Data[which(Data$Value2 < mean(Data$Value2)),"Date"] However, I am not sure how to get the mean of Value1 in the period, going 14 days forward from each of the resultant dates from the above code.

  • Upload file from client machine to server - prepopulate file picker path?

    - by user246114
    Hi, I'd like to upload a file from a client machine to my server. The user would have to specify the file to upload as I understand it, using a form that looks like: <input type="file" name="datafile" size="40"> This pops up a native file picker, which is great. The problem I'm having is that it's a real pain (for most users) to go looking around their machine for the file I'm interested in. Is there a way I can initialize the file picker with a path to make it more convenient for the user? Like I know some users will be on a windows machine, so I could prepopulate the picker by already sending them to the My Documents folder for example. I don't see how this is possible, just wondering if something like that exists, Thank you

  • How to use PHP Time function to set a time variable of '09:30', add a specific amount of seconds and

    - by Henry
    Hi guys, hopefully you can help me here. I have some code (please see below) which takes the current time, then adds specific seconds to the time and re-displays the time 1 minute in the future. Instead of the time being the current time, I want it to be a time which I set - say 9:30. Then I want to be able to add, for example 65 seconds and it shows me 9:31. Please can you show me how to change it from current time, to a specific time I can set myself. Thank you. <?php $my_time = date('h:i:s',time()); $seconds2add = 65; $new_time= strtotime($my_time); $new_time+=$seconds2add; echo date('h:i:s',$new_time); ?>

  • How can I convert (string) timestamp to mysql datetime on Windows 32 bit PHP?

    - by user239619
    I'm attempting to call LinkedIn's API and store Network Updates. Each update has a Unix timestamp that I'm retrieving as a string variable from the REST XML response. I want to convert the string timestamp to a mysql datetime format. The date() function accepts an integer as the second argument for time to be converted. However, I'm on Windows 32 bit PHP and the integer type for this platform is limited to 2147483647. $timestamp = '1293714626675'; // sample pulled from linkedin $timestamp = (int) $timestamp; // timestamp now equals 2147483647 $mysqlDatetime = date('Y-m-d H:i:s', $timestamp); // produces incorrect time Is there a better method of creating the mysql datetime in PHP? I realize that I can convert it upon insert into MySQL however, that would require changing other dependent code.

  • Coalesce and Case-When with To_Date not working as expected (Postgres bug?)

    - by ADTC
    I'm using Postgres 9.1. The following query does not work as expected. Coalesce should return the first non-null value. However, this query returns null (1?) instead of the date (2). select COALESCE( TO_DATE('','yyyymmdd'), --(1) TO_DATE('20130201','yyyymmdd') --(2) ); --(1) this evaluates independently to null --(2) this evaluates independently to the date, and therefore is the first non-null value What am I doing wrong? Any workaround? Edit: This may have nothing to do with Coalesce at all. I tried some experiments with Case When constructs; it turns out, Postgres has this big ugly bug where it treats TO_DATE('','yyyymmdd') as not null, even though selecting it returns null.

  • How do I convert german dates to MySQL standard dates?

    - by Kebman
    I'm importing a CSV file with dotted german dates into a MySQL database. I want the dates in the CSV to automatically be formatted correctly to the correct data type fields used by MySQL. I'm using Sequel Pro for the import. I gather I'm supposed to use the STR_TO_DATE function, but I just can't wrap my head around how to use add value or expression. German date Here are the dates in the CSV file: DD.MM.YYYY e.g.: 28.01.1978 MySQL date Here is what I want to end up with in the database: YYYY-MM-DD e.g.: 1978-01-28 Any ideas?

  • Vagrant reporting VirtualBox guest additions out of date

    - by DTest
    Fairly new to Vagrant, so bear with me if I don't understand the process. I downloaded a CentOS box off http://www.vagrantbox.es/ Started it up running VirtualBox 4.2.4 and got this message: [default] The guest additions on this VM do not match the install version of VirtualBox! This may cause things such as forwarded ports, shared folders, and more to not work properly. If any of those things fail on this machine, please update the guest additions and repackage the box. Guest Additions Version: 4.0.8 VirtualBox Version: 4.2.4 So I used the vbguest plugin to update the guest additions, then repackaged the box as suggested. Having replaced the old box and loading it up I get the same message about guest additions being outdated, but vbguest reports that they are up to date (the automatic vbguest update is disabled in my Vagrantfile): Vagrant::Config.run do |config| config.vm.box = "centos56_64" config.vbguest.auto_update = false config.vbguest.no_remote = true end And the commands: dtest$ vagrant up [default] Importing base box 'centos56_64'... [default] The guest additions on this VM do not match the install version of VirtualBox! This may cause things such as forwarded ports, shared folders, and more to not work properly.

  • Is there a way to change the date format used when InfoPath saves the form data to xml?

    - by Robert
    I have an InfoPath Form template that has some Date Picker controls in it bound to elements in an xml data source. I know I can change the display format of the date by going into the Date Picker Properties and setting the date format. This foramt is only used for display puposes when the form is being filled out. When the form is saved as an xml file the date is always stored in the format YYYY-MM-DD. Is there a way to change the date format that gets serialized to xml? I'm using InfoPath 2007.

  • clock and date showing on a live site but not on localhost

    - by grumpypanda
    I've got clock.swf and date.swf working fine on a live site, now I am using the same code to set up a local develop environment. Everything is working well except the clock.swf and date.swf stopped working on localhost. Two same yellow errors "You need to update your Flash plugin. Click here if you want to continue." but of course my Flash player is up to date since the live site is working fine. I'll post the code below which I think has caused the error. I've been searching online for the last couple of hours but no luck, anyone has got into an issue like this before? What can be the possible cause? Any help is appreciated.

  • SqlDateTime overflow on INSERT when date is correct using a Linq to SQL DataContext

    - by Jan Hoefnagels
    Dear Linq experts, I get an SqlDateTime overflow error (Must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM.) when doing an INSERT using an Linq DataContext connected to SQL Server database when I do the SubmitChanges(). When I use the debugger the date value is correct. Even if I temporary update the code to set the date value to DateTime.Now it will not do the insert. Did anybody found a work-around for this behaviour? Maybe there is a way to check what SQL the datacontext submits to the database.

  • Time and date dimension in data warehouse

    - by peperg
    I'm buildind an data warehouse. Each fact has it's timestamp. I need to create reports by day, month, quater but by hours too. Loking at the examples I see that dates tend to be saved in dimension tabels. But I think, that it makes no sense for time. The dimension table would grow and grow. On the other hand JOIN with date dimension table is more efficent than using date/time functions in SQL. What are your opinions/solutions ? (I'm using Infobright)

  • Avoid implicit conversion from date to timestamp for selects with Oracle 11g using Hibernate

    - by sapporo
    I'm using Hibernate 3.2.1 criteria queries to select rows from an Oracle 11g database, filtering by a timestamp field. The field in question is of type java.util.Date in Java, and DATE in Oracle. It turns out that the field gets mapped to java.sql.Timestamp, and Oracle converts all rows to TIMESTAMP before comparing to the passed in value, bypassing the index and thereby ruining performance. One solution would be to use Hibernate's sqlRestriction() along with Oracle's TO_DATE function. That would fix performance, but requires rewriting the application code (lots of queries). So is there a more elegant solution? Since Hibernate already does type mapping, could it be configured to do the right thing?

  • JAX-RS JSON java.util.Date Unmarshall

    - by user229498
    Hi, I'm using Jersey (jax-rs), to build a REST rich application. Everything is great, but I really don't understand how to set in JSON Marshalling and Unmarshalling converting option for dates and numbers. I have a User class: @XmlRootElement public class User { private String username; private String password; private java.util.Date createdOn; // ... getters and setters } When createdOn property is serialized, a string like this: '2010-05-12T00:00:00+02:00', but I need to choose date Pattern both, to marshall and unmarshall. Someone knows hot to do that? Thank's a lot, Davide.

  • Regex for date.

    - by Harikrishna
    What should be the regex for matching date of any format like 26FEB2009 30 Jul 2009 27 Mar 2008 29/05/2008 27 Aug 2009 What should be the regular expression for that ? I have regex that matches with 26-Feb-2009 and 26 FEB 2009 with but not with 26FEB2009. So if any one know then please update it. (?:^|[^\d\w:])(?'day'\d{1,2})(?:-?st\s+|-?th\s+|-?rd\s+|-?nd\s+|-|\s+)(?'month'Jan|Feb|Mar|Apr|May|Jun|Jul|Aug|Sep|Oct|Nov|Dec)[uarychilestmbro]*(?:\s*,?\s*|-)(?:'?(?'year'\d{2})|(?'year'\d{4}))(?=$|[^\d\w]) EDIT The date 26FEB2009 is substring of other string like FUTIDX 26FEB2009 NIFTY 0 and parsed from html page, so I can not set the whitespace or delimiter.

  • Date only from TextBoxFor()

    - by thekronos
    Hello, I'm having trouble displaying the only date part of a datetime into a textbox using TextBoxFor<,(expression, htmlAttributes). The model is based on Linq2SQL, field is a DateTime on SQL and in the Entity model. Failed : <%= Html.TextBoxFor(model => model.dtArrivalDate, String.Format("{0:dd/MM/yyyy}", Model.dtArrivalDate))%> Ps : this trick seems to be depreciated, any string value in the object htmlAttribute is ignored. Failed : [DisplayFormat( DataFormatString= "{0:dd/MM/yyyy}" )] public string dtArrivalDate { get; set; } I would like to store and display the date part only on the details/edit view without the "00:00:00" part. Any idea please ? Merry Chrismas from France to all by the way ;-)

  • mySQL date range problem

    - by StealthRT
    Hey all i am in need of a little help with figuring out how to get a range of days for my select query. Here is the code i am trying out: select id, idNumber, theDateStart, theDateEnd from clients WHERE idNumber = '010203' AND theDateStart >= '2010-04-09' AND theDateEnd <= '2010-04-09'; This is what the data in the table looks like: TheDateStart = 2010-04-09 TheDateEnd = 2010-04-11 When testing that code above, it does not populate anything. If i take out the TheEndDate, it populates but with some other tables data as well which it should not do (it should only get one record). I know the problem is within the two date's. I'm not sure how to go about getting a date range for theDateStart and theDateEnd since if someone tries it, say, on 2010-04-10, it still needs to know its within rage of the 2010-04-09 - 2010-04-11. But right now, it does not... Any help would be great! :o) David

  • VS2010 always thinks project is out of date but nothing has changed

    - by Christoph Ungersböck
    I have a very simmilar problem as described here. I also upgraded a mixed solution of C++/CLI and C# projects from VS2008 to VS2010. And one C++/CLI project always runs out of date. Even if it has been compiled and linked just before and F5 is hit the messagebox "The project is out of date. Would you like to build it?" appears. My pdb settings are set to default value (suggested solution of this problem). Any ideas?

  • Problem with Linq query and date format

    - by Alan T
    Hi All I have a C# console application written using Visual Studio 2008. My system culture is en-GB. I have a Linq query that looks like this: var myDate = "19-May-2010"; var cus = from x in _dataContext.testTable where x.CreateDate == Convert.ToDateTime(myDate) select x; The resulting SQL query generates and error because it returns the dates as "19/05/2010" which it interprets as an incorrect date. For some reason even though my system culture is set to en-GB it looks like it's trying to intrepret it as a en-US date. Any ideas how I get around this? Thanks. Alan T

  • Howto format a date as localized Short MonthDay string

    - by Wouter
    I would like to format a DateTime to a string containing the month name abbreviated and the date for use in axislabels in a graph. The default DateTime format strings do not contain abbreviated month. I guess there is no standard but I could take a substring of the first 3 characters of the month name and replace this into the MonthDay format. The reason I would use MonthDay is that the ordering of month and date is locale dependent. Does anyone have a better idea? http://msdn.microsoft.com/en-us/library/az4se3k1.aspx#MonthDay
