• NHibernate Many to Many delete all my data in the table

  - by Daoming Yang

  I would love to thank @Stefan Steinegger and @David helped me out yesterday with many-to-many mapping. I have 3 tables which are "News", "Tags" and "News_Tags" with Many-To-Many relationship and the "News_Tags" is the link table. If I delete one of the news records, the following mappings will delete all my news records which have the same tags. One thing I need to notice, I only allowed unique tag stored in the "Tag" table. This mapping make sense for me, it will delete the tag and related News records, but how can I implement a tagging system with NHibernate? Can anyone give me some suggestion? Many thanks. Daoming. News Mapping: <class name="New" table="News" lazy="false"> <id name="NewID"> <generator class="identity" /> </id> <property name="Title" type="String"></property> <property name="Description" type="String"></property> <set name="TagsList" table="New_Tags" lazy="false" inverse="true" cascade="all"> <key column="NewID" /> <many-to-many class="Tag" column="TagID" /> </set> </class> Tag Mapping: <class name="Tag" table="Tags" lazy="false"> <id name="TagID"> <generator class="identity" /> </id> <property name="TagName" type="String"></property> <property name="DateCreated" type="DateTime"></property> <!--inverse="true" has been defined in the "News mapping"--> <set name="NewsList" table="New_Tags" lazy="false" cascade="all"> <key column="TagID" /> <many-to-many class="New" column="NewID" /> </set> </class>

• Resize form based on if subform visible

  - by dmr

  I have a form with a subform on it. If subform contains no records, it's visible property is false. In that case, I'd like the outer form to shrink so that there isn't a big empty space where the subform was. The long way to do this would be by setting the position for all the controls on the form based on whether the subform is visible. However, is there an easier way to do this (maybe with the can grow/ can shrink property)?

• Setup my domain at Whois.com as nameservers for a Dedicated Server with Kloxo

  - by BoDiE2003

  Hello, this is my first time at ServerFault, I'm a stackoverflow user. I'm faceing the next problem and may be its me, but I can't find proper guides to set up a domain and nameservers for a dedicated box. I have a domain, at whois.com, and a Dedicated server at Reliable Hosting Services, the server has 5 IPs, I know that I need 2 of them for the nameservers. Right now, my domain at whois.com is using nsX.whois.com nameservers and it has 2 child nameservers: ns1.mydomain.com & ns2.mydomain.com pointing to those 2 IPs from my Server. Whats next? I still cannot set that domain as my main server domain since it says: To map an IP to a domain, the domain must ping to the same IP, otherwise, the domain will stop working. The domain you are trying to map this IP to, doesn't resolve back to the IP, and so it cannot be set as the default domain for the IP. Well and I'm stuck on those steps, whats next to have my nameservers working and my main domain assigned to my server? Thank you very much and happy new year!!

• What could be wrong with my VLAN?

  - by Matt

  I've got a VLAN 10 setup as a management VLAN. The management VLAN comes off port 48 and links to another set of switches that do not support VLAN's so it was I believe set up as an untagged access port. In the past this was a different brand of switch and this worked fine. However, since changing to the HP V1910-48G series I can't seem to get this working. I must point out that as far as I'm aware it is wired up properly (I can't check this physically as I'm working remote and have asked the tech who's got access to double check for me). Now I don't have a huge amount of experience with VLAN environments but AFAIK this is right. I've set the port 48 (linked to the management switches) as an untagged port with PVID 10 and access link type. Is this all I'd need to do from a configuration perspective to ensure all devices connected to port 48 would end up being on VLAN 10 and not needing to tag their frames. i.e. the tag would be added by the switch before being forwarded.

• 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?

• SQL server Agent - Not starting - Automatic start enabled

  SQL server agent is not starting automatically even when it is set to "Automatic". We have a weekend reboot of the server and usually it should come up automatically since it is set to "Automatic".

• Specify default group and permissions for new files in a certain directory

  - by mislav

  I have a certain directory in which there is a project shared by multiple users. These users use SSH to gain access to this directory and modify/create files. This project should only be writeable to a certain group of users: lets call it "mygroup". During an SSH session, all files/directories created by the current user should by default be owned by group "mygroup" and have group-writeable permissions. I can solve the permissions problem with umask: $ cd project $ umask 002 $ touch test.txt File "test.txt" is now group-writeable, but still belongs to my default group ("mislav", same as my username) and not to "mygroup". I can chgrp recursively to set the desired group, but I wanted to know is there a way to set some group implicitly like umask changes default permissions during a session. This specific directory is a shared git repo with a working copy and I want git checkout and git reset operations to set the correct mask and group for new files created in the working copy. The OS is Ubuntu Linux. Update: a colleague suggests I should look into getfacl/setfacl of POSIX ACL but the solution below combined with umask 002 in the current session is good enough for me and is much more simple.

• Using jQuery's ajax get request with parameters, returning page content

  - by Stevie Jenowski

  Thank you for looking at my question, as I appreciate your time. Okay, so I'm trying to use jQuery's get function to call my php script which ultimately returns a variable which is a built template of the main content of my page minus my static header/footer, for which I would like to replace the "old" page content without the page reloading. Can anyone point me in the right direction as to where I'm going wrong here? My code is as follows... jQuery: function getData(time, type) { $.ajax({ type: "GET", url: "getData.php", data: "time=" + time + "&type=" + type, success: function(data){ $('#pageContent').fadeOut("slow"); $('#pageContent').html(data); $('#pageContent').fadeIn("slow"); } }); return false; } getData.php(paraphrased): .... $time = empty($_GET['time']) ? '' : $_GET['time']; $type = empty($_GET['type']) ? '' : $_GET['type']; echo getData($time, $type); function getData($time, $type) ...... ..... $tmpl = new Template(); $tmpl->time= $time; $tmpl->type = $type; $builtpage = $tmpl->build('index.tmpl'); return $builtpage; ..... ...... jQuery function call: <a href="#" onclick="getData("<?php print $tmpl->time; ?>", "Orange")">Orange</a> <a href="#" onclick="getData("<?php print $tmpl->time; ?>", "Apple")">Apple</a> <a href="#" onclick="getData("<?php print $tmpl->time; ?>", "Banana")">Banana</a> When I click any link, the ajax seems to run fine, and the page does refuse to reload, but the content still remains unchanged... Anyone happen to know what's up?

• reference dll not copying to bin with deployment project causing error

  - by g.foley

  We have several external dlls being referenced in our Web Application Project. We have a deployment project for installing on the hosting servers. When we were using .net 3.5 and vs2008 the dll were being copied to the bin folder. Since we have upgraded to .net 4 vs2010 this no longer happens and we are getting servers errors since the references cannot be found. CopyLocal is set to true, and i cannot find anything inside the web.config which suggest this is being set else where.

• How to populate GridView if Internet not available but images already cached to SD Card

• machine learning and code generator from strings

  - by BCS

  The problem: Given a set of hand categorized strings (or a set of ordered vectors of strings) generate a decision function to categorize more input. The question: are there any tools out there that will do that? I'm thinking of some kind of reasonably polished, download, install and go kind of things, as opposed to to some library or a brittle academic program.

• memory leak on mdi with blank child form

  Hi, I've created a blank application with a mdi parent form opening a blank child form from the menu. When the parent form of the child form is set to the mdi - it appears the system does not release memory - thus a leak. When the parent form is not set, the child form is removed. Does anyone know why this apparent memory leak can be resolved? I've been using the ants memory profiler. Bob.
