• Retrieving multiple rows in SQL Server but distinct filtering only on one

  - by Nicklas

  I have this: SELECT Product.ProductID, Product.Name, Product.GroupID, Product.GradeID, AVG(tblReview.Grade) AS Grade FROM Product left Join tblReview ON Product.GroupID = tblReview.GroupID WHERE (Product.CategoryID = @CategoryID) GROUP BY Product.ProductID, Product.Name, Product.GroupID, Product.GradeID I would like to return only the rows where Product.Name is unique. If I make a SELECT DISTINCT the ProductID is different on every row so all the rows are unique.

• .htaccess Redirect Loop, adding multiple .php extensions

  - by Ryan Smith

  I have sort of a small parent/teacher social network set up for my school. I use my .htaccess file to make the links to teacher profiles cleaner and to add a trailing slash to all urls. I get this problem when going to /teachers/teacher-name/ the link (sometimes) redirects to /teachers/teacher-name.php.php.php.php.php.php.php.php... Below is my .htaccess file. Sometimes if I clear my browser cache in Chrome it temporarily fixes it. I can't exactly wright .htaccess syntax, but I'm pretty familiar with it. Any suggestions are appreciated! RewriteEngine on RewriteBase / #remove php ext RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME}\.php -f RewriteRule ^([^/]+)/$ $1.php RewriteRule ^([^/]+)/([^/]+)/$ $1/$2.php #force trailing slash/ RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)([^/])$ /$1$2/ [L,R=301] #other rewrites RewriteRule ^teachers/([^/\.]+)/$ /teachers/profile.php?u=$1 RewriteRule ^teachers/([^/\.]+)/posts/$ /teachers/posts.php?u=$1 RewriteRule ^teachers/([^/\.]+)/posts/([^/\.]+)/$ /teachers/post.php?u=$1&p=$2 RewriteRule ^gallery/([^/\.]+)/$ /gallery/album.php?n=$1 RewriteRule ^gallery/([^/\.]+)/slideshow/$ /gallery/slideshow.php?n=$1 RewriteRule ^gallery/([^/\.]+)/([^/\.]+)/([^/\.]+)/$ /gallery/photo.php?a=$1&p=$2&e=$3 EDIT:I have attached a screenshot of exactly what I'm talking about.

• Authenticating to multiple OUs in Active Directory

  - by Jaxidian

  I'm using the Active Directory Membership Provider with the following configuration: <connectionStrings> <add name="MyConnString" connectionString="LDAP://domaincontroller/OU=Product Users,DC=my,DC=domain,DC=com" /> </connectionStrings> <membership defaultProvider="MyProvider"> <providers> <clear /> <add name="MyProvider" connectionStringName="MyConnString" connectionUsername="my.domain.com\service_account" connectionPassword="biguglypassword" type="System.Web.Security.ActiveDirectoryMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" /> </providers> </membership> This works perfectly except it requires ALL of my users to be in the "Product Users" OU when I would actually like to have all of my users organized into various child OUs under our "Product Users" OU. Is this possible? (Note that this is a partial repost of this question but the question I'm asking here was never answered there.)

• Multiple delimiters using Regex.Split in C#

  - by Arthur Frankel

  Let's say you need to split a string by various delimiters including newline (/r, /n) and a few other 'special' character strings. For example: This is a sample %%% text &&& that I would like to split %%% into an array. I would like the following in the resulting string array (contents via index) [0]This is a sample [1]text [2]that I would [3]like to split [4]into an array. I would like to use C# Regex.Split() function. What is the regex expression to match on all of my delimiters? Thanks in advance

• WPF, Setting property with single value on multiple subcontrols

  - by Andre van Heerwaarde

  I have a parent contentcontrol which displays data via a datatemplate. The datatemplate contains a stackpanel with several usercontols of the same type. I like to set the property only once on the parent control, it must set the value of the property on all the subcontrols. But if there is a way to do it on the stackpanel it's also OK. The template can be changed at runtime and the values need also to be propagated to the new template. My current solution is to implement the property on both parent and subcontrol and use code to propagate the value from the parent to all the subcontrols. My question is: is there a better or other ways of doing this?

• Multiple remote_form_for on the same page causes duplicate ids

  - by Ben Scheirman

  I've got a rails app that displays a list of items called modules. I'm iterating over these, rendering a partial for each one that includes a remote_form_for call. This all works, but fails HTML validation because my form text fields all have the same id. Is there a :prefix option on the form (or something else) I can use to get around this? Update: (some code) //_module_form.html.erb <% remote_form_for app_module do |f| %> <%= f.label :name %> <%= f.text_field :name %> <%= submit_tag 'Save' %> <%end %> //parent page <% @thing.modules.each do |app_module| %> <%= render :partial => "module_form", :locals => { :app_module => app_module } %> <% end %> So if I have more than 1 item in the collection, I render the identical form on the same page, and the form id and textbox id are duplicated. I can customize the form id pretty easily, but what about the text_box, since the controller is looking for specific named controls?

• Best way to deal with multiple layouts in symfony

  - by Pierre

  Hey folks. I'm looking for the best way to do something simple in symfony. Basically, I have a module in which all the pages will contain the same header and footer. That module also shares the same general layout as the other modules. I'm just wondering, should I create one file and have my content pages called up as partials or should all files have their own content and somehow call the two other templates. I made a quick example of my setup: http://grab.by/3Riy Hopefully, it'll help understand what I'm trying to do. Thanks!

• JSF actionListener is called multiple times from within HtmlTable

  - by Rose

  I have a mix of columns in my htmltable: 1 column is an actionlistener, 2 columns are actions and other columns are simple output. <h:dataTable styleClass="table" id="orderTable" value="#{table.dataModel}" var="anOrder" binding="#{table.dataTable}" rows="#{table.rows}" <an:listenerColumn backingBean="${orderEntry}" entity="${anOrder}" actionListener="closeOrder"/ <an:column label="#{msg.hdr_orderStatus}" entity="#{anOrder}" propertyName="orderStatus" / <an:actionColumn backingBean="${orderEntry}" entity="${anOrder}" action="editOrder" / <an:actionColumn backingBean="${orderEntry}" entity="${anOrder}" action="viewOrder"/ .... I'm using custom tags, but it's the same behavior if I use the default column tags. I've noticed a very strange effect: when clicking the actionlistenercolumn, the actionevent is handled 3 times. If I remove the 2 action columns then the actionevent is handled only once. The managed bean has sessionscope, bean method: public void closeOrder(ActionEvent event) { OrdersDto order; if ((order = orderRow()) == null) { return; } System.out.println("closeOrder() 1 "); orderManager.closeOrder(); System.out.println("closeOrder() 2 "); } the console prints the'debug' text 3 times.

• Enable UIBarButtonItem if multiple UITextFields are all populated

  - by CrystalSkull

  I have 3 UITextFields in a grouped UITableView and am trying to figure out the correct logic to only have my 'Save' UIBarButtonItem enabled when none of the UITextFields are empty. I'm currently using the - (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string UITextField delegate method to detect changes to the field character by character, but it is providing inconsistent results. Any ideas?

• Using delayed_job to process file uploads across multiple servers

  - by Steve Klabnik

  Does anyone have any good resources on how to do this? Basically, I'm working on a project (in Rails) where people can upload files. They might be big. I'd like to process them using delayed_job before sending them to S3. I'd also like to do this processing on a separate job queue server, rather than on the webserver itself. I'd rather not have to upload the files to the webserver, then transfer them to the job queue server, and then upload them to S3 if I don't have to. Thanks.

• Mapping multiple keys to the same value in a Javascript hash

  - by Bears will eat you

  I use a Javascript hash object to store a set of numerical counters, set up like this [this is greatly simplified]: var myHash = { A: 0, B: 0, C: 0 }; Is there a way to make other keys, ones not explicitly in myHash, map to keys that are? For instance, I'd like [again, this is simplified]: myHash['A_prime']++; // or myHash.A_prime++; to be exactly equivalent to myHash['A']++; // or myHash.A++; e.g. incrementing the value found at the key A, not A_prime.

• Reportviewer - Print report - matrix report expanding horizontally to multiple pages, avoid repeating row header

  - by abc0077

  I am generating a matrix report dynamically using report viewer version 9.0 in visual studio 2010. If i export save and print then it works normally. If there more columns report expands horizontally across mutiple pages. If i give Print option available in the toolbar of the report viewer. The columns are moved to second page which is correct but the row headers (product 1, product 2) should not be repeated in the second page.In the second page report should have all details except the product information. I am also interested to know whether it is the functionality of this version report viewer.

• Multiple Servers with identical services

  - by Jerry Bailey

  I have a dozen servers in different locations all running the same web service application but each going against their own SQL Server DB. I am writing a desktop application that consumes the web services. I want to present the user with a drop down of all servers in the network that are running the same wweb service application. Do I have to add a ServiceReference for each of the servers running the web service app and thereby having as many proxies as there are servers? Or can a define a single instance of the services and dynamically build a list of endpoints to select from a drop down?

• PHP: saving multiple tuples to the same table

  - by Binaryrespawn

  Hi all, I am trying to save data into the same table several times from the same $_POST array. You see, on my registration form a family is allowed to specify the names, gender and age of all members they wish to bring along. This data is being stored in a database table called aditional_member. Based on family size, I am dynamically generating html table rows where each row has the number of input fields required. <tr id="additionalmember_3"> <td><input type="text" name="first_name1" maxlength="50" value="" /></td> <td><input type="text" name="last_name1" maxlength="50" value="" /></td> td><select name="gender1" value="" ><option value='Male'>Male</option><option value='Female'>Female</option></select></td> <td><select name="age_group"value="" ><option value='18 to 30'>18 to 30</option><option value='31 to 60'>31 to 60</option></select></td> </tr> When I POST, let us say I have three sets of input(3 table rows as above), Is there a simple way to insert into the addional_member table the data from row one, then row two, and so on. I tried looping the insert statement, which failed. I am basically open to suggestions, I do not need to use a table. Any ideas, Thank you.

• Packing differently sized chunks of data into multiple bins

  - by knizz

  EDIT: It seems like this problem is called "Cutting stock problem" I need an algorithm that gives me the (space-)optimal arrangement of chunks in bins. One way would be put the bigger chunks in first. But see how that algorithm fails in this example: Chunks Bins ----------------------------- AAA BBB CC DD ( ) ( ) Algorithm Result ----------------------------- biggest first (AAABBB ) (CC ) optimal (AAACCDD) (BBB) "Biggest first" can't fit in DD. Maybe it helps to build a table like this: Size 1: --- Size 2: CC, DD Size 3: AAA, BBB Size 4: CCDD Size 5: AAACC, AAADD, BBBCC, BBBDD Size 6: AAABBB Size 7: AAACCDD, BBBCCDD Size 8: AAABBBCC, AAABBBDD Size 10: AAABBBCCDD

• Multiple websites, Single sign-on design

  - by Yannis

  Hi all, I have a question. A client I have been doing some work recently has a range of websites with different login mechanisms. He is looking to slowly migrate to a single sign-on mechanism for his websites (all written in asp.net mvc). I am looking at my options here, so here is a list of requirements: 1) It has to be secure (duh) 2) It needs to support extra user properties over and above the usual name, address stuff (such as money or credits for a user) 3) It has to provide a centralized user management web console for his convenience (I understand that this will be a small project on top of whatever design solution I choose to go for) 4) It has to integrate with the existing websites without re-engineering the whole product (I understand that this depends on the current product implementation). 5) It has to deal with emailing the user when he registers (in order for him to activate his account) 6) It has to deal with activating the user when he clicks the activate me link in the email (I understand that 5 and 6 require some form of email templating system to support different emails per application) I was thinking of creating a library working together with forms authentication that exposes whatever methods are required (e.g. login, logout, activate, etc. and a small restful service to implement activation from email, registration processing etc. Taking into account that loads of things have been left out to make this question brief and to the point, does this sound like a good design? But this looks like a very common problem so arent there any existing projects that I could use? Thanks for reading.

• How can I make a single WCF method ConcurrencyMode.Multiple when service is ConcurencyMode.Single
