  • Why Date Format in ASP NET MVC Differs when used inside Html Helper?

    - by Marcio Gabe
    Hi, I just came across a very interesting issue. If I use ViewData to pass a DateTime value to the view and then display it inside a textbox, even though I'm using String.Format in the exact same manner, I get different formatting results when using the Html.TextBox helper. <%= Html.TextBox("datefilter", String.Format("{0:d}", ViewData["datefilter"]))%> <input id="test" name="test" type="text" value="<%: String.Format("{0:d}", ViewData["datefilter"]) %>" /> The above code renders the following html: <input id="datefilter" name="datefilter" type="text" value="2010-06-18" /> <input id="test" name="test" type="text" value="18/06/2010" /> Notice how the fist line that uses the Html helper produces the date format in one way while the second one produces a very different output. Any ideas why? Note: I'm currently in Brazil, so the standard short date format here is dd/MM/yyyy.

  • How can I delete a file created and opened with Perl's IO::File and XML::Writer?

    - by Sho Minamimoto
    So I'm running through a list of things and have code that creates an .xml files with IO::File called $doc, then I make a new writer with XML::Writer(OUTPUT => $doc). More code runs and I build a big XML file with XML::Writer. Then, near the end of the file, I find out if I need this file at all. If I do need it, I just: $writer->end(); $doc->close(); but if I don't need it, what should I enter to just delete all data I've stored/saved and move onto the next file? I tried unlink($docpath) (before and after $doc->close()), the file was not deleted.

  • function to find common rows between more than two data frames in R

    - by biohazard
    I have 4 data frames, and would like to find the rows whose values in a certain column do not exist in any of the other data frames. I wrote this function: #function to test presence of $Name in 3 other datasets common <- function(a, b, c, d) { is.B <- is.numeric(a$Name %in% b$Name) == 1 is.C <- is.numeric(a$Name %in% c$Name) == 1 is.D <- is.numeric(a$Name %in% d$Name) == 1 t <- as.numeric(is.B & is.C & is.D) t } However, the output is always t = 0. This means that it tells me that there are no unique rows in any data sets, even though the datas frames have very different numbers of rows. Since there are no duplicate rows in any of the data frames, I should be getting t = 1 for at least some rows in the biggest dataset. Can someone figure out what I got wrong?

  • Ruby on Rails - Currency : commas causing an issue.

    - by easement
    Looking on SO, I see that the preferred way to currency using RoR is using decimal(8,2) and to output them using number_to_currency(); I can get my numbers out of the DB, but I'm having issues on getting them in. Inside my update action I have the following line: if @non_labor_expense.update_attributes(params[:non_labor_expense]) puts YAML::dump(params) The dump of params shows the correct value. xx,yyy.zz , but what gets stored in the DB is only xx.00 What do I need to do in order to take into account that there may be commas and a user may not enter .zz (the cents). Some regex and for comma? how would you handle the decimal if it were .2 versus .20 . There has to be a builtin or at least a better way. My Migration (I don't know if this helps): class ChangeExpenseToDec < ActiveRecord::Migration def self.up change_column :non_labor_expenses, :amount, :decimal, :precision => 8, :scale => 2 end def self.down change_column :non_labor_expenses, :amount, :integer end end

  • Preserving original StackTrace/LineNumbers in .NET Exceptions

    - by Sam
    Understanding the difference between throw ex and throw, why is the original StackTrace preserved in this example: static void Main(string[] args) { try { LongFaultyMethod(); } catch (System.Exception ex) { Console.WriteLine(ex.StackTrace); } } static void LongFaultyMethod() { try { int x = 20; SomethingThatThrowsException(x); } catch (Exception) { throw; } } static void SomethingThatThrowsException(int x) { int y = x / (x - x); } But not in this one: static void Main(string[] args) { try { LongFaultyMethod(); } catch (System.Exception ex) { Console.WriteLine(ex.StackTrace); } } static void LongFaultyMethod() { try { int x = 20; int y = x / (x - 20); } catch (Exception) { throw; } } The second scenario is producing the same output as throw ex would? In both cases, one expects to see the line number where y is initialized.

  • Adjusting Timezone - Convert XML DateTime to SQL DateTime

    - by noob.spt
    We are using TypedDataSet in our application. Data is passed to procedure in form of XML for insert/update. Now after populating DE with data, datetime remains the same though timezone information is added as below. Date in DB: 2009-10-29 18:52:53.43 Date in XML: 2009-10-29T18:52:53.43-05:00 Now when I am trying to convert below XML to SQL DateTime it is adjusting 5 hours and I am getting 2009-10-29 23:52:53.430 as the final output, which is wrong. Need to find a way to extract datetime from below XML snippet ignoring timezone. I have XML in following format, with timezone difference -05.00 <Order> <EnteredDateTime>2009-10-29T18:52:53.43-05:00</EnteredDateTime> </Order>

  • Committing file deletions to svn repository whilst ignoring some other local mods

    - by TheJuice
    I have svn repository where I have scheduled some files and folders to be moved in the repository with svn mv. I also have some files that are peers of the files to be moved that have local modifications of which I only want a subset of those files to be committed along with the moves. e.g. the output of svn st would look like: D foo/bar D foo/bar/a.txt D foo/bar/b.txt M foo/exclude.txt M foo/include.txt A foo/whiz/bar A + foo/whiz/bar/c.txt A + foo/whiz/bar/d.txt To commit to the moves to the repository, I would need to perform the commit on foo but that would also commit the modifications to foo/exclude.txt and foo/include.txt. How would I commit only the deletions/additions as a result of the move plus the mods to foo/include.txt whilst excluding foo/exclude.txt? I have a feeling the answer lies with the --depth argument to svn ci but it's not clear to me how it will operate.

  • How does struts 1.X ActionForm handle pure html checkbox list?

    - by BlueDolphin
    I am dealing with an old application which uses struts 1.2. And for some reason, we are using pure html form to submit to struts action. For example: for the content output of testAction.do, I try to submit to itself. item 1 item 2 Then I associate an form bean TestForm with testAction. I am not sure how to specify the properties in the form so that it take the value from myitem1 after user click "submit" I tried to add getMyitem1(), setMyitem1(String[] items), getSelectedMyitem1(), setSelectedMyitem1(String[] items) Those set methods are only called when page are loaded. I guess my understanding of ActionForm in struts 1.x must be wrong. Please advise, thanks.

  • SQL Server - Compare int values in a select clause

    - by Russell
    This is what I thought would be a simple select clause, however the following is giving me grief! I am using SQL Server 2008. Basically I want to compare two integer values and return the boolean result in the select clause. Here is a simple example: DECLARE @A INT DECLARE @B INT SET @A = 1 SET @B = 2 SELECT @A = @B Currently the only output is "Command(s) completed successfully." Where I reasonably believe it is assigning @A to @B. I thought this would be simple but have not been able to achieve this. Any help would be great! Thanks

  • How to remove the file extension in a zsh completion?

    - by meeselet
    I want to adjust zsh so that I can tab complete: myprog <tab> using all *.foo files in ~/somedir, but have it so that it displays them without the .foo extension. Is there any way to do this? This is what I have so far: #compdef myprog typeset -A opt_args local context state line local -a mydirs mydirs="(. ~/somedir)" _arguments -s -S \ "*:name:->foos" \ && return 0 case $state in (foos) _files -W ${mydirs} -g '*.foo(:r)' && return 0 ;; esac return 1 However, this displays double the output for every file (that is, each .foo file is listed with and without its extension). Is there any way around this?

  • Database Design: A proper table design for large number of column values.

    - by Jake
    I wish to perform an experiment many different times. After every trial, I am left with a "large" set of output statistics -- let's say, 1000. I would like to store the outputs of my experiments in a table, but what's the best way...? Option 1 Have a table with 1000 columns. Seems like a bad idea. What if the number of statistics one day exceeds the maximum number of columns? Option 2 Have a table with three columns. Let's say, ID, StatisticType, and StatisticValue. That way, you can have as many statistics as you want. However, reading a single experiments statistics becomes more complicated. Moreover, what if different statistics are different data types?? Any suggestions?

  • What is the fastest way to trim blank lines from beginning and end of array?

    - by Edward Tanguay
    This script: <?php $lines[] = ''; $lines[] = 'first line '; $lines[] = 'second line '; $lines[] = ''; $lines[] = 'fourth line'; $lines[] = ''; $lines[] = ''; $lineCount = 1; foreach($lines as $line) { echo $lineCount . ': [' . trim($line) . ']<br/>'; $lineCount++; } ?> produces this output: 1: [] 2: [first line] 3: [second line] 4: [] 5: [fourth line] 6: [] 7: [] What is the fastest, most efficient way to change the above script so that it also deletes the preceding and trailing blank entries but not the interior blank entries so that it outputs this: 1: [first line] 2: [second line] 3: [] 4: [fourth line] I could use the foreach loop but I imagine there is a way with array_filter or something similar which is much more efficient.

  • MySQL calling in Username to show instead of ID!

    - by Jess
    I have a users table, books table and authors table. An author can have many books, while a user can also have many books. (This is how my DB is currently setup). As I'm pretty new to So far my setup is like bookview.php?book_id=23 from accessing authors page, then seeing all books for the author. The single book's details are all displayed on this new page...I can get the output to display the user ID associated with the book, but not the user name, and this also applies for the author's name, I can the author ID to display, but not the name, so somewhere in the query below I am not calling in the correct values: SELECT users.user_id, authors.author_id, books.book_id, books.bookname, books.bookprice, books.bookplot FROM books INNER JOIN authors on books.book_id = authors.book_id INNER JOIN users ON books.book_id = users.user_id WHERE books.book_id=" . $book_id; Could someone help me correct this so I can display the author name and user name both associated with the book!

  • Rerversing AND Bitwise.

    Hey all, Here's the following algorithm: int encryption(int a, int b) { short int c, c2; uint8_t d; c = a ^ b; c2 = c; d = 0; while(c) { c &= c - 1; d++; } return d; } How can I find which variable a and b I should send in that function to decide of the output value of d? In other words, how can I reverse the algoritm to let's say if I want d=11?

The function in c must be declared with the specific prototype (but this program does not contain the prototype) why the program give the output 'x'for the char variable ? can the function in c are capable of accepting the value without being declared about type in parameters like what has done in the function declaration ?

  • What is "sentry object" in C++?

    - by Romain Hippeau
    I answered this question, and Potatoswatter answered too as The modern C++ equivalent would be a sentry object: construct it at the beginning of a function, with its constructor implementing call(), and upon return (or abnormal exit), its destructor implements I am not familiar with using sentry objects in C++. I thought they were limited to input and output streams. Could somebody explain to me about C++ sentry objects as well as how to use them as an around interceptor for one or more methods in a class ? i.e. How to do this ? Sentry objects are very similar indeed. On the one hand they require explicit instantiation (and being passed this) but on the other hand you can add to them so that they check not only the invariants of the class but some pre/post conditions for the function at hand.

  • Track/Display Array Index As Part Of Cout (C++)

    - by John Smith
    Hi, I have a command line C++ program that lets you enter basic information about a person (ID number, name, age, etc.) and I want to output to a console in the following manner: ------------------------------------------------------------------- Index ID # First Name Last Name Age ------------------------------------------------------------------- 0 1234 John Smith 25 The person objects are stored in an array of Persons and I've overload the ostream (<<) operator to print out all of the fields like you see. The dashed lines and header come from a displayHdg() function. Anyhow, I have not been able to figure out how to get the proper index value for the array. Ideally, I'd like to generate the indices for each line, but all my attempts have failed. The array is looped through and each object printed in the main() function, and the ostream is overloaded in a person class, so I tried to use global variables as well as static variables, and all of those produce incorrect numbering (i.e. show 0, 1 the first time (for 2 objects), then change to 1, 2 on the next display). Any ideas?

  • PERL XPath Parser Help

    - by cognvision
    I want to pull in data using a XML::XPath parser from a XML DB file from the Worldbank site. The problem is that I'm not seeing any results in the output. I must be missing something in the code. Ideally, I would like to extract just the death rate statistics from each country XML DB (year and value). I'm using this as part of my input: http://data.worldbank.org/sites/default/files/countries/en/afghanistan_en.xml use strict; use LWP 5.64; use HTML::ContentExtractor; use XML::XPath; my $agent1 = LWP::UserAgent->new; my $extractor = HTML::ContentExtractor->new(); #Retrieve main Worldbank country site my $mainlink = "http://data.worldbank.org/country/"; my $page = $agent1->get("$mainlink"); my $fulltext = $page->decoded_content(); #Match to just all available countries in Worldbank my $country = ""; my @countryList; if (@countryList = $fulltext =~ m/(http:\/\/data\.worldbank\.org\/country\/.*?")/gi){ foreach $country(@countryList){ #Remove " at the end of link $country=~s/\"//gi; print "\n" . $country; #Retrieve each country profile's XML DB file my $page = $agent1->get("$country"); my $fulltext = $page->decoded_content(); my $XML_DB = ""; my @countryXMLDBList; if (@countryXMLDBList = $fulltext =~ m/(http:\/\/data\.worldbank\.org\/sites\/default\/files\/countries\/en\/.*?\.xml)/gi){ foreach $XML_DB(@countryXMLDBList){ my $page = $agent1->get("$XML_DB"); my $fulltext = $page->decoded_content(); #print $fulltext; #Use XML XPath parser to find elements related to death rate my $xp = XML::XPath->new($fulltext); #my $xp = XML::XPath->new("afghanistan_en.xml"); my $nodeSet = $xp->find("//*"); if (!$nodeSet->isa('XML::XPath::NodeSet') || $nodeSet->size() == 0) { #No match found print "\nMatch not found!"; exit; } else { foreach my $node ($nodeSet->get_nodelist){ print "\n" . $node->find('country')->string_value; print "\n" . $node->find('indicator')->string_value; print "\n" . $node->find('year')->string_value; print "\n" . $node->find('value')->string_value; exit; } } } #Build line graph based on death rate statistics and output some image file format } } } I am also looking into using the xpath expression "following-sibling", but not sure how to use it correctly.

  • I'd like to know why a function executes fine when called from x but not when called from y

    When called from archive(), readcont(char *filename) executes fine! Called from runoptions() though, it fails to list the files "archived"! why is this? The program must run in terminal.

  • Configuring a library to be included with C++ test

    - by vrish88
    Hello, I would like to utilize the UnitTest++ library in a testing file. However, I am having some difficulty getting the library to be included at compile time. So here is my current directory structure: tests/ UnitTests++/ libUnitTest++.a src/ UnitTests++.h unit/ test.cpp I have just used the UnitTest++ getting started guide to just get the library setup. Here is test.cpp: // test.cpp #include <UnitTest++.h> TEST(FailSpectacularly) { CHECK(false); } int main() { return UnitTest::RunAllTests(); } And I am currently trying to compile with: gcc -lUnitTest++ -L../UnitTest++/ -I../UnitTest++/src/ test.cpp I am currently getting a bunch output with ld: symbol(s) not found at the end. So how would I be able to get the UnitTest++ library properly included when this program is compiled? I am on a Mac and I'd also like for there to be an easy way for people on a Linux machine to run these same tests. Whew, I hope this provides enough information, if not please let me know.

  • MySQL INSERT data does not get stored in proper db, only temporary?

    - by greye
    I'm having trouble with MySQL or Python and can't seem to isolate the problem. INSERTs only seem to last the run of the script and are not stored in the database. I have this script: import MySQLdb db = MySQLdb.connect(host="localhost", user="user", passwd="password", db="example") dbcursor = db.cursor() dbcursor.execute("select * from tablename") temp = dbcursor.fetchall() print 'before: '+str(temp) dbcursor.execute('INSERT INTO tablename (data1, data2, data3) VALUES ("1", "a", "b")') dbcursor.execute("select * from tablename") temp = dbcursor.fetchall() print 'after: '+str(temp) The first time I run it I get the expected output: >>> before: () after: ((1L, 'a', 'b'),) The problem is that if I run it again, the before comes out empty when it should already have the entry in it and the after doesn't break (data 1 is primary key). >>> before: () after: ((1L, 'a', 'b'),) >>> before: () after: ((1L, 'a', 'b'),) >>> before: () after: ((1L, 'a', 'b'),) If I try running the insert command twice in the same script it will break ("Duplicate entry for PRIMARY KEY") Any idea what might be happening here?

  • Headless HTML rendering to image on CentOS 5.4

    - by Jim Tough
    Hello, I have a project requirement to render HTML and capture the rendered image as a file on a headless CentOS 5.4 server. My specific requirements are: 1) Input will be a URL to the page to render, output will be an image file containing the rendered image of the page 2) CSS must be supported by the renderer up to CSS level-1 3) Static images in the page must be displayed properly in the rendered image, including any transparent color in .GIF files 4) Must be able to run on a headless CentOS 5.4 server. 5) Solution must not depend on any product or component that is not free for commercial use I do not need to do anything with the page other than get the screen capture and save it to an image. The hard part seems to be doing this in a headless environment. Some of the solutions that I've seen discussed need a display in order to work. Any suggestions? Thanks in advance, Jim

  • Storing a reference to an object in C#

    - by Jack
    I was wondering how one could store a reference to an object in .net. That is, I would like something like the following code (note, of course, that the following code may be way off from how to actually do it): class Test { private /*reference to*/ Object a; public Test(ref int a) { this.a = a; this.a = ((int)this.a) + 1; } public Object getA() { return this.a; } } /* * ... */ static void Main(string[] args) { int a; a=3; Test t = new Test(ref a); Console.WriteLine(a); Console.WriteLine(t.getA()); Console.ReadKey(); } To produce the following output: 4 4 Ideally, I would like to do this without writing a wrapper class around the integer. In other words, I think I want pointers in .Net.
