• heirarchial data from self referencing table in tree form

  - by Beta033

  Ii looks like this has been asked and answered in all the simple cases, excluding the one that i'm having trouble with. I've tried using a recursive CTE to generate this, however maybe a cursor would be better? or maybe a set of recursive functions will do the trick? Can this be done in a cte? consider the following table PrimaryKey ParentKey 1 NULL 2 1 3 6 4 7 5 2 6 1 7 NULL should yield PK 1 -2 --5 -6 --3 7 -4 where the number of - marks equal the depth, my primary difficulty is the ordering.

• SQL Server (2008) Creating link tables with unique rows

  - by peteski22

  Hi guys, I'm having trouble getting in touch with SQL Server Managemen Studio 2008! I want to create a link-table that will link an Event to many Audiences (EventAudience). An example of the data that could be contained: EventId | AudienceId 4 1 5 1 4 2 However, I don't want this: EventId | AudienceId 4 1 4 1 I've been looking at relationships and constraints.. but no joy so far! As a sneaky second part to the question, I would like to set up the Audience table such that if a row is deleted from Audience, it will clear down the EventAudience link table in a cascading manner. As always, ANY help/advice appreciated! Thanks Pete

• C# Design a class with interface?

  - by Haroon

  I am having a bit of trouble understanding how I will design a class. My class will have 3 methods ICollection<Field> GetFields(); //perform validation internally - return back the object T UpdateFields(ICollection<Field> fields); //pass in model object with values on it, set up fields, then pass back all fields ICollection<Field> GetFieldsWithValues(T object); What is the best way to construct/design such a class keeping in mind: 1. The model object I pass in will be one of 3 or 4 tables, however when I call GetFIelds - internally for each object I know what fields will be there i.e. list.add(new Field{name = "id", value = "5"}); list.add(new Field{name = "nameofcompany", value = "super guys"});

• Drupal 6 CCK node form redirect issue

  - by swdv

  Hi, I am having trouble with a multi-step node form for a CCK content type. I set $form_state['redirect'] to a thank you page path, but it does not get redirected upon successful submission. Here is the code following documentation on the Drupal 5.x to 6.x form API at http://drupal.org/node/144132 function rnf_form_alter(&$form, &$form_state, $form_id) { // ... $form['#submit'][] = 'rnf_regret_form_submit'; } function rnf_regret_form_submit($form, &$form_state) { $form_state['redirect'] = 'content/forget-thank-you'; } Any help would be appreciated. Thanks.

• JSP Problem ussing implicit object (session) in a function

  - by user234666

  Can the object of type HttpSession called session be accessed from a function? In a simple jsp page I have a function(see below) defined in the header of the page, and set to an onclick handle of for a button. When I press this button, I'll never see the second alert message. If I do something in the body of the page (like Session ID: <%= session.getId() % ) I have no trouble accessing it. What newbie mistake am I making? function doTest() { alert('Preforming test 122333232'); String sessionId = session.getId(); alert('After access'); if(sessionId == null) { alert('session id is null?'); } Thanks

• Object Recognition from Templates

  - by JonLeah

  Hi Guys, I was hoping someone could point me in the right direction here. With a picture of a die (from above) I want to recognize which side is up. I understand the basics in play here, but I'm having trouble grasping the power of OpenCV. I imagine I want a picture of each side of the die. Then I can somehow compare them all to the current image to be classified. How can I use OpenCV to do this? Thanks, Jonathan

• Class-Dump Installation

  - by sj-dev

  So this may sound like a really stupid question and I HAVE looked at the how-to from the parent website, but no matter what I do, I cannot get this program to even start to install... I tried entering: cd /opt/local/bin/portslocation/dports/class-dump which returned a "this file/director doesnt exist" error, so i tried to get to it folder by folder. when i got all the way to: cd /opt/local/bin/ i cannot go any further. when i check the contents of the bin directory, the only files i can find are (and i cannot access these apparently either): "daemondo port portf portindex portmirror" i have tried doing this on 2 computers so far to no avail, macports is installed on both like the website said and i am having trouble finding any support for it. please and thank you!!

• slow record deletion with large ntext values

  - by asking

  I'm having trouble deleting some records via a stored procedure from a table in SQLServer 2008R2 that has ntext columns. The stored proc is timing out and running the query directly takes a very long time. The initial query was a straight "delete from y where x = z" and I've also tried running it in batches of 1000 with transactions but it is still slow and timing out in a stored proc. The majority of the records in the table will not be deleted each time (it's not just a once-off query but will be run other times). The ntext columns are not used in the where clause and I can't change the column types. Any suggestions on the quickest way to delete records with large ntext values? Thanks

• What should I do in order to be able to work with maven + eclipse + wicket + hibernate + spring in M

  - by spderosso

  I want to create a web app that will use wicket, hibernate and spring frameworks. My IDE of choice is Eclipse, I am using maven for the .war generation and I am running Mac OS. What steps should I follow to correctly install and configure all the tools so as to have a project running that relies on these 3 frameworks. I was able to successfully set up wicket but I am having trouble for setting up hibernate and spring. I went through multiple tutorials but I still couldn't find the solution. Thanks!

• can anyone explain the why the the 1st example gets different results than the following 2

  - by klumsy

  $b = (2,3) $myarray1 = @(,$b,$b) $myarray1[0].length #this will be 1 $myarray1[1].length $myarray2 = @( ,$b ,$b ) $myarray2[0].length #this will be 2 $myarray[1].length $myarray3 = @(,$b ,$b ) $myarray3[0].length #this will be 2 $myarray3[1].length UPDATE I think on #powershell IRC we have worked it out, Here is another example that demonstrates the danger of breaking with the comma on the following line rather than the top line when listing multiple items in an array over multiple lines. $b = (1..20) $a = @( $b, $b ,$b, $b, $b ,$b) for($i=0;$i -lt $a.length;$i++) { $a[$i].length } "--------" $a = @( $b, $b ,$b ,$b, $b ,$b) for($i=0;$i -lt $a.length;$i++) { $a[$i].length } produces 20 20 20 20 20 20 -------- 20 20 20 1 20 20 I'm curious how people will explain this. I think i understand it now, but would have trouble explaining it in a concise understandable fashion, though the above example goes somewhat towards that goal.

• Is it possible to run C++ binded with SDL+OpenGL code on a web browser?

  - by unknownthreat

  My client wants her website to have an application that renders 3D (light 3D stuff, we are drawing only flat squares in 3D world) but web programming is not my thing. So I am looking for something that can run a C++ program from a web browser. But I think, if this is the case, then the client side must download the program first, and that's not what I want. The client should only be able to use this application only on the website. I came across Google Native Client, which claims that it can run x86 native code in web applications. I haven't decide whether it is worth it or not and I don't know whether this is what I want or not, so I decided to ask experienced people about this. If I want to have something like this, is what I said above possible? Or I completely need other languages like Flex because it does not worth the trouble? Or is Google Native Client suitable for doing something like this?

• Is Kohana worth giving up on due to lack of Documentation & Examples?

  - by Asaf

  Hello, I've recently chose Kohana for a new project I'm doing And quite frankly, it's going a bit slow due to lack of resources. I've stumbled again and again on problems that I can't find a solution to Examples are probably the hardest to come by, so I'm considering Switching, especially because I'm only starting and I am still able to do it without to much trouble. I've been looking at CodeIgniter, although I know that Kohana is a branch out, CodeIgniter has far more examples and documentation, I'm wondering about your opinion. Edit: I would love to see some complete Kohana sites example, so that I would have a really quick reference. Nothing like already-working code to give you inspiration.

• Hooking a synchronous event handler on a form submit button in JS

  - by Xzhsh

  Hi, I'm working on a security project in javascript (something I honestly have not used), and I'm having some trouble with EventListeners. My code looks something like this: function prevclick(evt) { evt.preventDefault(); document.loginform.submitbtn.removeEventListener('click',prevclick,false); var req = new XMLHttpRequest(); req.open("GET","testlog.php?submission=complete",false); req.send(); document.loginform.submitbtn.click(); //tried this and loginform.submit() } document.loginform.submitbtn.addEventListener('click',prevclick,false); But the problem is, the submit button doesn't submit the form on the first click (it does, however, send the http request on the first click), and on the second click of the submit button, it works as normal. I think there is a problem with the synchronization, but I do need to have the request processed before forwarding the user to the next page. Any ideas on this would be great. Thanks in advance.

• IIS 7 problem which does not occur under apache

  - by cc0

  I'm hosting a little site using a JavaScript to draw a simple graph. It involves one html index file, some css and some js files. It has all been working perfectly on two different apache servers, but when I set up IIS 7 the ajax calls fail. I get no java debug errors in firefox that I can work with, or any kind of error message at all. Without going into the code itself, does anyone have a similar experience with IIS? This is the first time I'm using IIS so I'm not quite sure what to expect to have trouble with. I'd love some input on this, if I have to delve into the code itself I'll make a new thread, I just thought I'd see if this could be a typical issue. Any help is appreciated!

  Hi, I'm having trouble authenticating as a specific user on MS Team Foundation Server. In older versions it would look like: teamFoundationCredential = new System.Net.NetworkCredential("<USERNAME>", "<PASSWORD>", "<DOMAIN>"); TeamFoundationServer tfs = new TeamFoundationServer("http://mars:8080/", teamFoundationCredential); Can some one tell me the equivilent for the 2010 version. So far I have: ICredentialsProvider cred = null; tfs = TfsTeamProjectCollectionFactory.GetTeamProjectCollection(new Uri("http://asebeast.cpsc.ucalgar.ca:8080/tfs/DefualtCollection")); tfs.EnsureAuthenticated(); Thanks

• how to insert page view of a node in another page in drupal

  - by sprugman

  I have a list of node ids and I want to display the 'page' view of each one. For various reasons, I don't want to do this with views, and don't think I should need a module. Just an API call to theme('node'). Something like: $nids = array(3,4,5); foreach ($nids as $nid) { $node = node_load($nid); $result .= theme('node', $node); } but I'm not getting back the full page view of the node. I added this to my node-[type].tpl.php file: if ($page) print "PAGE MODE "; else print "NOT PAGE "; if ($teaser) print "TEASER MODE "; else print "NOT TEASER "; and got: NOT PAGE NOT TEASER I seem to be in some kind of limbo. I suspect there's an argument that I add to the theme function, but the terms are all so general (theme, teaser, page, node), I'm having trouble with my google-fu.

• How to write following MongoDB query in C# Driver?

  - by user3043457

  I wrote the exact query I need in Mongo console, but I'm having trouble rewriting it in C# driver. Here's a sample of the document, it's simple dictionary: { "_id" : ObjectId("539716bc101c588f941e2c27"), "_t" : "DictionaryDocument", "CsvSeparator" : ",", "SelectedAccounts" : "0", ... } Here's the query: db.settings.find({"SelectedAccounts" :{$exists:true}},{"SelectedAccounts":1, "_id":0} ) Now, I got the first part, Find with exists working, but how to write the second parameter in C# driver? I'd just like a single string as a result, not entire document. Here's C# code I got so far: _collection.FindOneAs(typeof(DictionaryDocument), Query.Exists(key)); key in this case is "SelectedAccounts". I'd like the query to filter and return only the data I need, I don't want to return all the results and search on the C# side. EDIT: I wouldn't mind if _id was passed back, but I don't need it. So only this part would work if it could be converted in C#: db.settings.find({"SelectedAccounts" :{$exists:true}},{"SelectedAccounts":1} )

• How to use Eclipse's Display View for Debug?

  - by jzd

  At the link below it explains that the "display view allows you to manipulate live code in a scrapbook type fashion (see Figure 8). To manipulate a variable, simply type the name of the variable in the Display view, and you'll be greeted with a familiar content assist." http://www.ibm.com/developerworks/library/os-ecbug/ However, I am having trouble getting it to work. I have the view open but all the buttons are disabled. I have tried putting code in the view, selecting code in the view, selecting code in other views, while running and while not running debug, but the only button that is ever enabled on the view is "clear console". Suggestions on what I am doing wrong?

• SQLite problem with some parameterized queries

  - by Trevor Balcom

  I am having some trouble using SQLite and parameterized queries with a few tables. I have noticed some queries using the "SELECT * FROM Table WHERE row=?" are returning 1 row when there should be more rows returned. If I change the parameterized query to "SELECT * FROM Table WHERE row='row'" then the correct number of rows is returned. Does anyone know why sqlite3_step would return only 1 row when using a parameterized query vs. using the same query in a traditional non-parameterized way? I am using a very thin C++ wrapper around SQLite3. I suspect there could be a problem with the wrapper, but this problem only exists on a few tables. It makes me wonder if there is something wrong with the way those tables are setup. Any advice is appreciated.
