  • How can I make the Entity data model designer use my database column descriptions?

    - by Jack
    I am using EF4 with Visual Studio 2010. I have a SQL database already created and all my columns are documented with the Description property in SQL management studio. When I create the edmx in Visual Studio, how can I make it read those descriptions and use them to add comments to my generated classes? I know I can use the Summary and LongDescription in the edmx properties but I'm looking for a way to do this without having to copy and paste every description. Thanks!

  • encode array to JSON in PHP to get [elm1,elm2,elm3] instead of {elm1:{},elm2:{},elm3:{}}

    - by Itay Moav
    I am trying to json_encode an array, which is what returns from a Zend_DB query. var_dump gives: (Manually adding 0 member does not change the picture). array(3) { [1]=> array(3) { ["comment_id"]=> string(1) "1" ["erasable"]=> string(1) "1" ["comment"]=> string(6) "test 1" } [2]=> array(3) { ["comment_id"]=> string(1) "2" ["erasable"]=> string(1) "1" ["comment"]=> string(6) "test 1" } [3]=> array(3) { ["comment_id"]=> string(1) "3" ["erasable"]=> string(1) "1" ["comment"]=> string(6) "jhghjg" } } The encoded string looks: {"1":{"comment_id":"1","erasable":"1","comment":"test 1"}, "2":{"comment_id":"2","erasable":"1","comment":"test 1"}, "3":{"comment_id":"3","erasable":"1","comment":"jhghjg"}} While I need it as: [{"comment_id":"1","erasable":"1","comment":"test 1"}, {"comment_id":"2","erasable":"1","comment":"test 1"}, {"comment_id":"3","erasable":"1","comment":"jhghjg"}] As the php.ini/json__encode documentation says it should. Any ideas?

  • Question about ASP.NET MVC and static data (ie. images, scripts, etc)

    - by Pure.Krome
    Hi folks, If i have a request for a resource in my ASP.NET MVC1 (or 2) web app for a static resource, say ... an image or a javascript file or a css file ... does the .NET framework try and see if the request matches the route list ... and eventually can't find a controller for it? eg. Resource: /Content/Images/Foo.png Does this request go through my route list .. fails to match any controllers / actions to this request and then .. i donno ... attempt that path directly?

  • How to use $.get data to replace certain elements in a webpage?

    - by Jack Ha
    I'm using jQuery 1.4.2 to navigate smoothly between similar webpages (in ff3). When clicking on a link, a javascript script should load the new html, filter out the right elements and replace them on the current page. It looks like the $(htmlcode) does not do the thing I expected. The actions below work when loading the page directly, but when using the $.get I have the following problems: the find function seems only to look inside a div element called id="page", which is inside the body element one of the elements has <script>...</script>, but the <script>...</script> is not present in the DOM of $(htmlcode). Anybody knows how to solve this? $.get( url, function(responseText, textStatus, xmlHttpRequest) { alert($(responseText).find("#header")); // works, #header is inside div#page alert($(responseText).find("#header").html()); // displays content, but WITHOUT the <script>...</script> alert($(responseText).find("title")); // does not work, title is outside div#page } );

  • Database design advice needed.

    - by user346271
    Hi all, I'm a lone developer for a telecoms company, and am after some database design advice from anyone with a bit of time to answer. I am inserting into one table ~2 million rows each day, these tables then get archived and compressed on a monthly basis. Each monthly table contains ~15,000,000 rows. Although this is increasing month on month. For every insert I do above I am combining the data from rows which belong together and creating another "correlated" table. This table is currently not being archived, as I need to make sure I never miss an update to the correlated table. (Hope that makes sense) Although in general this information should remain fairly static after a couple of days of processing. All of the above is working perfectly. However my company now wishes to perform some stats against this data, and these tables are getting too large to provide the results in what would be deemed a reasonable time. Even with the appropriate indexes set. So I guess after all the above my question is quite simple. Should I write a script which groups the data from my correlated table into smaller tables. Or should I store the queries result sets in something like memcache? I'm already using mysqls cache, but due to having limited control over how long the data is stored for, it's not working ideally. The main advantages I can see of using something like memcache: No blocking on my correlated table after the query has been cashed. Greater flexibility of sharing the collected data between the backend collector and front end processor. (i.e custom reports could be written in the backend and the results of these stored in the cache under a key which then gets shared with anyone who would want to see the data of this report) Redundancy and scalability if we start sharing this data with a large amount of customers. The main disadvantages I can see of using something like memcache: Data is not persistent if machine is rebooted / cache is flushed. The main advantages of using MySql Persistent data. Less code changes (although adding something like memcache is trivial anyway) The main disadvantages of using MySql Have to define table templates every time I want to store provide a new set of grouped data. Have to write a program which loops through the correlated data and fills these new tables. Potentially will still grow slower as the data continues to be filled. Apologies for quite a long question. It's helped me to write down these thoughts here anyway, and any advice/help/experience with dealing with this sort of problem would be greatly appreciated. Many thanks. Alan

  • Why would you precede the main() function in C with a data type?

    - by Milktrader
    Many are familiar with the hello world program in C #include <stdio.h> main () { printf ("hello world"); return 0; } Why do some precede the main () function with int as in: int main() Also, I've seen the word 'void' entered inside the () as in: int main(void) It seems like extra typing for nothing, but maybe it's a best practice that pays dividends in other situations? Also, why precede main() with an int if you're returning a character string? If anything, one would expect: char main(void) I'm also foggy about why we return 0 at the end of the function.

  • oracle index for string column - does format of data affects quality of index?

    - by Jayan
    We have following type of "Unique ID" column for many tables in the database (Oracle). It is a string with following format <randomnumber>-<ascendingnumber>-<machinename> So we have some thing like this U1234-12345-NBBJD U1234-12346-NBBJD U1234-12347-NBBJD U1234-12348-NBBJD U1234-12349-NBBJD The UID value is unique, we have unique index on them. Does the following format is more efficient than above for index scans? NBBJD-U1234-12345 NBBJD-U1234-12346 NBBJD-U1234-12347 NBBJD-U1234-12348 NBBJD-U1234-12349

  • Best practice: How to persist simple data without a database in django?

    - by Infinity
    I'm building a website that doesn't require a database because a REST API "is the database". (Except you don't want to be putting site-specific things in there, since the API is used by mostly mobile clients) However there's a few things that normally would be put in a database, for example the "jobs" page. You have master list view, and the detail views for each job, and it should be easy to add new job entries. (not necessarily via a CMS, but that would be awesome) e.g. example.com/careers/ and example.com/careers/77/ I could just hardcode this stuff in templates, but that's no DRY- you have to update the master template and the detail template every time. What do you guys think? Maybe a YAML file? Or any better ideas? Thx

  • T-SQL - Is there a (free) way to compare data in two tables?

    - by RPM1984
    Okay so i have table a and table b. (SQL Server 2008) Both tables have the exact same schema. For the purposes of this question, consider table a = my local dev table, table b = the live table. I need to create a SQL script (containing UPDATE/DELETE/INSERT statements) that will update table b to be the same as table a. This script will then be deployed to the live database. Any free tools out there that can do this, or better yet a way i can do it myself? I'm thinking i probably need to do some type of a join on all the fields in the tables, then generate dynamic sql based on that. Anyone have any ideas?

  • Looping class, for template engine kind of thing

    Hey, I am updating my class Nesty so it's infinite but I'm having a little trouble....

  • C++: Simple data type for a variable in IF statement?

    - by Jason
    I am new to C++ and am making a simple text RPG, anyway, The scenario is I have a "welcome" screen with choices 1-3, and have a simple IF statement to check them, here: int choice; std::cout << "--> "; std::cin >> choice; if(choice == 1) { //.. That works fine, but if someone enters a letter as selection (instead of 1, 2 or 3) it'll become "-392493492"or something and crash the program. So I came up with: char choice; std::cout << "--> "; std::cin >> choice; if(choice == 1) { //.. This works kinda fine, but when I enter a number it seems to skip the IF statements completely.. Is the char "1" the same as the number 1? I get a compiler errro with this (ISO-CPP or something): if(choice == "1") So how on earth do I see if they entered 1-3 correctly!?

  • Troubleshooting multiple GET variables In PHP

    - by V413HAV
    This may be a very simple question but I don't what's the wrong thing am doing here... To explain you clearly, I've set a real simple example below: <ul> <li><a href="test.php?link1=true">Link 1</a></li> <li><a href="test.php?link2=true">Link 2</a></li> <li><a href="test.php?link3=true">Link 3</a></li> </ul> <?php if(isset($_GET['link1'])) { if(($_GET['link1']) == 'true') { echo 'This Is Link 1'; } } if(isset($_GET['link2'])) { if(($_GET['link2']) == 'true') { echo 'This Is Link 2'; } } if(isset($_GET['link3'])) { if(($_GET['link3']) == 'true') { echo 'This Is Link 3'; } } ?> This is a test.php page, here I've set 3 different arguments for $_GET, and show contents accordingly, now everything works perfect, the only thing am not understanding is how to block this kind of url say if user clicks on link 1 the url will be : http://localhost/test.php?link1=true And the Output of this url is This is Link 1 Now if I change this url to : http://localhost/test.php?link3=true&link2=true&link1=true And the Output what I get is This Is Link 1This Is Link 2This Is Link 3 Now this is ok here, but it's very annoying if someone types this and see's forms one below the other, any way I can stop this tampering?

  • Need help debugging a huge chunk of JSON data...

    - by meder
    I have a huge chunk, so large that I can't manually edit the file and need to read it in and do regex operations to see what's wrong. Basically - my server is PHP 5.1.6 and I can't update it. This features an older json_decode which is less featured than the 5.2/5.3 versions. json_decode returns NULL and json_last_error is being invoked but the function doesn't exist except in PHP 5.3 so I'm manually trying to see what's wrong. $regex = '#[^0-9"$a-zA-Z{:}().]#'; $json = preg_replace( $regex, '', $json ); $tree = json_decode ( $json, true ); var_dump($tree); // NULL A snippet of the JSON.. somewhere in the middle {"109":0,"103":1,"102":59,"101":70,"100":4299,"94":0,"50":51,"46":0,"45":0,"44":0,"43":0,"42":0,"23":0,"22":0,"18":0,"17":1,"16":1,"13":160,"8":4298}},"2":{"d":{"109":0,"103":92,"102":54,"101":53,"100":4301,"94":0,"50":4278,"49":328,"46":1,"45":0,"44":1,"43":0,"42":0,"26":0,"23":0,"22":0,"18":0,"17":1,"16":1,"8":4300},"m":{"94":1,"100":1,"26":1,"50":1,"8":1,"49":1,"18":1,"43":1,"42":1,"109":1},"c":{"\/":{"d":{"109":0,"100":4301,"94":0,"50":4278,"49":328,"43":0,"42":0,"26":0,"18":0,"8":4300}},"G":{"d":{"109":1,"100":4303,"94":1,"68":17,"50":64,"49":53,"43":1,"42":1,"34":0,"18":1,"13":2216,"11":0,"8":4302}}}},"3": The }}}} is suspicious but this probably just closes 4 nested object literals. Would appreciate any insight.

  • How can I incorporate a data bound list of MenuItems to another MenuItem in WPF?

    - by Julien Poulin
    I have a 'File' MenuItem were I would like to display a list of recently opened files. Here is the xaml I have now: <MenuItem Header="File}"> <MenuItem Header="Preferences..." Command="{Binding ShowOptionsViewCommand}" /> <Separator /> <ItemsControl ItemsSource="{Binding RecentFiles}"> <ItemsControl.ItemTemplate> <DataTemplate> <MenuItem Header="{Binding DisplayPath}" CommandParameter="{Binding}" Command="{Binding Path=DataContext.OpenRecentFileCommand, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type Window}}}"> </MenuItem> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> <Separator /> <MenuItem Header="Exit" Command="{Binding CloseCommand}" /> </MenuItem> However, when I use this code, there is a weird offset around the MenuItems and it looks like there is a container around them. How can I get rid of that? Here is a screenshot of what it looks like:

  • How do you extract data from a Date/Time widget from a C++ MFC dialog in VS2008

    - by jkerian
    This is a fairly basic question, but I haven't been able to find any from-to guides from VS6-VS2008. I have a dialog box that contains controls of various types, I've discovered the way of auto-generating OnBnClickedMyFooBarButtonHere() methods via the Properties dialog on the dialog editor. I can also use CWnd::GetDlgItemText(int ,CString &) to extract text, and the oddly paramaterized GetDlgItemInt(int, bool*, bool) to extract signed integers, but is there really no other option for a Date or Time value other than Manually adding in all the DDX_ crap that the class wizard used to do in VS6 Using GetDlgItemText and then parsing whatever it gives me?

  • Store data in an inconvenient table or create a derived table?

    - by user1705685
    I have a certain predefined database structure that I am stuck with. The question is whether this structure is OK for ORM or I whether should add a processing layer that would create a more convenient structure every time something is inserted into the original DB. To simplify, here's what it kind of looks like. I have a person table: PersonId Name And I have a properties table: PersonId PropertyType PropertyValue So, for person John Doe... (1, 'John Doe') ...I could have three properties: (1, 'phone', '555-55-55'), (1, 'email', '[email protected]), (1, 'type', 'employee') By using ORM I would like to get a "person" object that would have properties "name", "phone", "email", "type". Can Propel do that? How efficient is it? Is it a better idea to create a table with columns "phone", "email", "type" and fill it automatically as new rows are inserted into the properties table?
