• Using Mod_Rewrite in HTTPD.CONF file

  - by Mike Lovely

  I want to rewrite URLs so when a user goes to; http://www.example.com/applications/newWeb/www/index.php?page=48&thiscontent=2660&date=2013-10-11&pubType=0&PublishTime=09:30:00&from=home&tabOption=1 and if the URL contains thiscontent=2660 (which in this example above, it does) I want to redirect them to; http://www.example.come/index.php/publications/finance-and-economics/departmental-resources I have about 30 different thiscontent=XXXX types and imagine I’ll have to copy and edit this rule 30 different times for any links to my old website still knocking around out there. I have access to my httpd.conf file but have never done a mod_rewrite before. I also don't really need these showing up in the error logs as 301s. Will that happen? Because at the moment there are hundreds!

• WAMP & WordPress - Having issues after installing plugins

  - by user1786083

  I am using WAMP (Apache 2.2.17, PHP 5.4.3) & WordPress 3.4.2. Everything was fine until I started to add and activate plugins now I get different sort of errors on the front-end/Admin e.g. "Notice: Undefined index: plugin_version in C:\repo\wpdev\wp-content\plugins\wp-rss-multi-importer\inc\upgrade.php on line 11" And "Warning: Illegal string offset 'feedslug' in C:\repo\wpdev\wp-content\plugins\wp-rss-multi-importer\inc\rss_feed.php on line 21." IF I deactivate the plugins everything seems to be fine. I have installed WAMP & WP 2X. The plugins work fine on MediaTemple. The error messages vary depending on the plugins. Search Google and came up empty. Thanks in advance.

• I can't use achiva as a proxy of my remote repository

  - by user1553915

  I want to install Achiva to manage my Maven repositories. I add a new internal repository called "public" and a new remote repository, which is my company's repository. Then I configure the proxy connector to let the repository "public" to be a proxy of the remote one. But When I enter the address "http://localhost:8084/archiva/repository/public/.../....pom" in the web brower,error occurred "Unable to fetch artifact resource". However, if I replace the remote repository with another one such as "http://repository.codehaus.org/", the proxy works. I don't know why this happens, are there something wrong with my remote repository address?

• Entity framework Update fails when object is linked to a missing child

  - by McKay

  I’m having trouble updating an objects child when the object has a reference to a nonexising child record. eg. Tables Car and CarColor have a relationship. Car.CarColorId CarColor.CarColorId If I load the car with its color record like so this var result = from x in database.Car.Include("CarColor") where x.CarId = 5 select x; I'll get back the Car object and it’s Color object. Now suppose that some time ago a CarColor had been deleted but the Car record in question still contains the CarColorId value. So when I run the query the Color object is null because the CarColor record didn’t exist. My problem here is that when I attach another Color object that does exist I get a Store update, insert error when saving. Car.Color = newColor Database.SaveChanges(); It’s like the context is trying to delete the nonexisting color. How can I get around this?

• link_to syntax with rails3 (link_to_remote) and basic javascript not working in a rails3 app?

  - by z3cko

  i am wondering if the basic link_to syntax is completely broken in current rails3 master or if i am doing some wrong syntax here. = link_to "name", nil, :onlick => "alert('Hello world!');" should actually produce an alert on click. very simple. does not work on my rails3 project! (also no error output!) any ideas? for the general link_to syntax i could not find an example where i could combine a link_to_remote with a confirmation, remote and html class (see my try below) = link_to "delete", {:action => "destroy", :remote => true, :method => :delete, :confirm => "#{a.title} wirklich L&ouml;schen?" }, :class => "trash" even the rails3 api does not help me here: http://rails3api.s3.amazonaws.com/index.html help!

• Viewstate seems to be hijacked inadvertently

  - by dvr

  Hi, we are using asp.net 2.x, we use session state stored in sql server, 2 web servers in loadbalance, iis6. our issue is that in the last 3 months we have had 2 cases where some one using our enquiry form has seen someone else's info e.g. first name and last name. We are not populating the form from objects in session so I have come to the conclusion that the second user has somehow received the viewstate from the first user, after that user has tried to submit and got an error e.g. has posted view state and returned the the same page and the other user has requested that page at the same time (must have been on the same server I am guessing if it is a viewstate issue). have any of you experienced this before? some questions mulling around in my head is how does the worker process know to retun view state to a unique request and how does it determine a unique request etc..

• How can I search for the dot character using the search command?

  - by lk

  I'm trying to use the Search command in Vim: :Rs/F/T/X R = range F = text to find T = text to replace with X = options But, when I want to search for the "." (dot character) I'm getting some problems. The task: Replace all occurences of " ." (space dot) for "" (greater-than) So, first I tried this: :%s/ ./>/g But this changed me all the " ." (space ANY-CHARACTER) to the "" character. Then I remembered that the dot character is a special one, so I tried this: :%s/ \./>/g But vim threw me an error: E486 Can't find pattern " \." And finally I tried this crazy thing: :%s/" ."/>/g and this :%s/" \."/>/g But I got the same result: E486 Can't find pattern... So, how can I search for the dot character using the search command? PS: Sorry for my poor Enlish.

• the correct actionscript to find if object already exists

  - by touB

  I have a Rect object that I'd like to create and set its properties only once. After that, I want to just modify its properties since it already exists. This is my general idea if(theRect == undefined){ Alert.show("creating"); var theRect:Rect = new Rect(); //then set properties addElement(theRect); //then add it using addElement because addChild() does not work } else { Alert.show("updating"); //no need to create it since it's already been created //just access and change the properties } I tried several ways and combinations for the if conditional check: if(theRect == undefined){ if(theRect == null){ declaring and not declaring `var theRect:Rect;` before the if check declaring and instantiating to null before the if check `var theRect:Rect = null;` but can't get the desired effect. Everytime this code block runs, and depending on which version I've used, it either gives me a "can't access null object" error or the if statement always evaluates to true and creates a new Rect object and I get the "creating" Alert. What's the right way of creating that Rect but only if doesn't exist?

• How can you check if a file exists before including/importing it in JSP?

  - by codeninja

  Assuming that requestScope.importMe is expecting a path to a jsp file <c:choose> <c:when test="${!empty requestScope.importMe && fileExists(requestScope.importMe) }"> <c:import url="${requestScope.importMe}" /> ... How can I check if the file exists before trying to include it so that an error is not thrown? I'd like to avoid using inline Java. Something using one of the JSTL tags is the preferred approach.

• Shell scripting and test expressions

  - by Paul

  Hi, I'm trying to test whether a directory path exists when a file is passed to my script. I use dirname to strip and save the path. I want my script to run only if the path exists. This is my attempt below. FILE=$1 DIRNAME=dirname $FILE if [ -z $DIRNAME ] ; then echo "Error no file path" exit 1 fi But this doesn't work. Actual when there is no file path dirname $FILE still returns "." to DIRNAME, i.e. this directory. So how do i distinguish between "." and "/bla/bla/bla". Thanks.

• JSON Response {"d":"128.00"} but displaying "128"

  - by TGuimond

  Hi all, I have been working on a shopping cart that the user can add/remove order items as they please and am returning an updated sub-total via a webservice using jQuery $.ajax Here is how I am calling the webservice and setting the sub-total with the response. //perform the ajax call $.ajax({ url: p, data: '{' + s + '}', success: function(sTotal) { //order was updated: set span to new sub-total $("#cartRow" + orderID).find(".subTotal").text(sTotal); }, failure: function() { //if the orer was not saved //console.log('Error: Order not deleted'); } }); The response I am getting seems perfectly fine: {"d":"128.00"} When I display the total on the page it displays as 128 rather than 128.00 I am fully sure it is something very simple and silly but I am so deep into it now I need someone with a fresh brain to help me out!! Cheers :)

• Common files in output directories in a C# program

  - by Net Citizen

  My VS2008 solution has the following setup. Program1 Program2 Common.dll (used and referenced by both Program1 and Program2) In debug mode I like to set my output directory to Program Files\Productname, because some code will get the exe path for various reasons. My problem is that Program1 when compiled, will give an error that it could not copy Common.dll if Program2 is started. And vise versa. The annoyance here is that I don't even make changes to Common.dll that often, but 100% of the time it will try to copy it, not only when there are changes. I end up having to close all programs, and then build and then start them. So my question is, how can I only have VS2008 copy the Common.dll if there are changes inside the Common.dll project?

• Cadr of a list involving assoc function

  - by user3619045

  I have looked around on the net and cant find an answer to my query. I would really appreciate if someone could provide a good answer without down rating this post. In Lisp car, cdr are used on data mode like '(whatever here) which makes sense to me. Now, in the book Land of Lisp the author is explaining how to build a text engine and suddenly he uses the following description to make a function. (defun describe-location (location nodes) (cadr (assoc location nodes))) Can I ask why is he doing a cadr on a list and how come it provides a response and not an error? shouldn't it be a data mode i.e with a quote in front of the opening bracket '(whatever here)? and also why is he using assoc as in (assoc location nodes) and not (assoc 'garden *nodes*) Isn't the second correct way to use assoc ? I may be missing the big picture and as such would really appreciate someone explaining these key points please. Many thanks!

• Django admin panel doesn't work after modify default user model.

  - by damienix

  I was trying to extend user profile. I founded a few solutions, but the most recommended was to create new user class containing foreign key to original django.contrib.auth.models.User class. I did it with this so i have in models.py: class UserProfile(models.Model): user = models.ForeignKey(User, unique=True) website_url = models.URLField(verify_exists=False) and in my admin.py from django.contrib import admin from someapp.models import * from django.contrib.auth.admin import UserAdmin # Define an inline admin descriptor for UserProfile model class UserProfileInline(admin.TabularInline): model = UserProfile fk_name = 'user' max_num = 1 # Define a new UserAdmin class class MyUserAdmin(UserAdmin): inlines = [UserProfileInline, ] # Re-register UserAdmin admin.site.unregister(User) admin.site.register(User, MyUserAdmin) And now when I'm trying to create/edit user in admin panel i have an error: "Unknown column 'content_userprofile.id' in 'field list'" where content is my appname. I was trying to add line AUTH_PROFILE_MODULE = 'content.UserProfile' to my settings.py but with no effect. How to tell panel admin to know how to correctly display fields in user form?

• Replace data in MySQL table with data from another table

  - by Oli

  I am trying to modify an existing MySQL database for use in a new application. I have a table of items (table_items), which has multiple fields, including "ItemID" and "ItemName". I have another table (table_list) which has "ItemName" in it, but no ItemID. I need to either update this table to contain ItemID instead of ItemName, or create a new table which imports ItemIDs from table_items as opposed to the ItemName when table_list.ItemName = table_items.ItemName. I have tried the following: UPDATE table_list A, table_items B SET A.ItemName = B.ItemID WHERE A.ItemName = B.ItemName The current table has over 500,000 rows and every time i try this in PHPMyAdmin i get the error "the MySQl server has gone away". Any help greatly appreciated.
