• Why does changing LCD screen resolution (Windows 7) take several seconds?

  - by Jakub P.

  Why does it take so long for a computer monitor to change resolution? Why does it take 2-3 seconds rather than, say, 50 ms? E.g. my current Windows 7 with strong GPU and 24 inch monitor takes 2-3 seconds. Why so long? I know some might say "it's JUST 2 seconds", but come on... Games produce hundreds of FPS, and monitors work at 60 Hz, so what is it that takes so much time? I remember this was the same in just about any machine I ever worked with.

• I want to reformat my external hard disk but disk utility said it could not be unmounted

  - by Faith

  Hi I wanted to reformat my HP 500GB hard disk to MS DOS (FAT) by using Disk Utility but Disk Utility kept saying that the hard disk cannot be unmounted. I tried googling it but nothing seems to answer my question. I'm not trying to reformat the hard disk in my Mac but my external hard disk! I usually format my hard disks to clear the documents I no longer need. And I'll change it to ExFat but currently, whenever I plug in my hard disk on Windows, the whole system just hangs there. Can someone help??

• Finding the unique paths through a Neo4j graph

  - by Larry

  I have a Neo4j graph with 12 inputs and 4 outputs, and am trying to write a query with the Java Traverser that will return the 14 unique paths from an input to an output node. All the queries I have tried return only a subset of the 14 paths. For example, the code below returns 4 paths, but the other 10 all stop 1 node short of the output. RelationshipType relType = RelationshipTypes.EDGE; TraversalDescription td = new TraversalDescriptionImpl() .depthFirst() .relationships(relType, Direction.OUTGOING); for (Node node : inputs){ Traverser tv = td.traverse(node); Iterator<Path> iter = tv.iterator(); // ... print path } I've tried uniqueness and depth settings as well, with no effect. The query below returns all 14 paths using the web interface, but when I use the ExecutionEngine class, I only get 13 paths back. START s=node(*) MATCH (s)-[p:EDGE*]->(c) WHERE s.type! = "INPUT" AND c.type! = "OUTPUT" RETURN p How do I get all the unique paths using the Java API?

• Load Balancing and High Availability for Web Site

  - by nzgirl

  We've developing a database driven (70%/30% read/write load) website using C#.NET, IIS and MS SQL Server 2008 to be hosted on Windows 2008. Due to contractual reasons our setup has to be hosted on our own physical/virtual servers instead of a cloud solution at this stage. Could someone outline or link to some best practices that would provide both high availability (priority at the moment) and eventually load balancing for our site. We're probably looking at some sort of 2 SQL server mirrored system and 2 ISS web servers to start with. Thanks in advance.

• How do you assign resources and keep begin, end and duration of a task intact?

  - by Random

  I have problems with assigning more than one resource to a group of tasks. The idea is simple, my tasks are in one group and are manually scheduled to particular begin and end dates. I want to assign more than one resource to keep task duration and dates (fixed duration) and increase work. For top level tasks it works fine but as long tasks are grouped, the duration of each is extended to reach group end date and work remains. For the problematic tasks, the Gantt chart looks like this: One resource attached (good) ( Task 1.1 ) ( Task 1.2 ) (Task 1.3) More than one resource attached (wrong) ( Task 1.1 )....................... ( Task 1.2 ).......... (Task 1.3) So for tasks like that, I want to have a fixed schedule and just increase work by adding resources that work in the same time, but sometimes MS Project does leveling to do resources work sequentialy.

• Codeigniter - Active record - sql - complex join

  - by Jack

  I have a function that retrieves all tags from a table: function global_popular_tags() { $this->db->select('tags.*, COUNT(tags.id) AS count'); $this->db->from('tags'); $this->db->join('tags_to_work', 'tags.id = tags_to_work.tag_id'); $this->db->group_by('tags.id'); $this->db->order_by('count', 'desc'); $query = $this->db->get()->result_array(); return $query; } I have another table called 'work'. The 'work' table has a 'draft' column with values of either 1 or 0. I want the COUNT(tags.id) to take into account whether the work with the specific tag is in draft mode (1) or not. Say there are 10 pieces of work tagged with, for example, 'design'. The COUNT will be 10. But 2 of these pieces of work are in draft mode, so the COUNT should really be 8. How do I manage this?

• Merged rows in column, bottom row fixed height

  - by Styxxy

  I've been struggling some time now with a specific problem using Tables in MS Word (2010). I have a table with 2 rows and 2 columns and the last column, the rows are merged. Now it can happen that this last cell will expand, and I would like to have the last row in the first column to be of a fixed height and the first row has to expand. What happens now is that the last row expands and the first row has a "fixed" height. A picture of the behaviour at this moment: And this is how I would like it to behave: I have been looking through all properties and settings, but I don't seem to find any option. Neither can I found anything by searching online (probably not using the exact right keywords). Any help is appreciated.

• In what platforms/browsers does Adobe Flash come preinstalled?

  - by Michael Haren

  In what platforms/browsers does Adobe Flash come preinstalled? I'm pretty sure neither FireFox nor Safari include it on any platform but Chrome on Windows does (not sure about Mac or Linux). What about IE on a completely vanilla Win XP system? Or Win 7? Maybe mfgs like Dell add it if MS doesn't? Perhaps we can find (or build) a comprehensive list. Considering that Flash is a significant piece of the web platform, I hope I've asked this on the right place.

• IntelliPoint & Intellitype upgrade to Mouse and Keyboard Center causing system freeze?

  - by Kent England

  I allowed Microsoft to upgrade my wireless keyboard 6000 v3.0 and mouse 6000 v2.0 from Intelliyada v 8.20.468 to what appears to be v9.1.486. This was some time ago, so I can't be certain but this upgrade might be causing my system to freeze on the logon screen (user selection) in Windows 7 Home Premium 32-bit. Mouse and keyboard don't work, but system seems to be running underneath. No indication in Event Viewer about keyboard/mouse driver issues. Might be problem with transceiver hardware. I now have the "Microsoft Mouse and Keyboard Center" UI which isn't very helpful (seems to be very metro) in debugging these drivers. I'm just looking to see if anyone else had problems upgrading to this new Intelliyada software for their MS keyboard and rodent.

• PHP - Calling function inside another class -> function

  - by Kolind

  I'm trying to do this: class database { function editProvider($post) { $sql = "UPDATE tbl SET "; foreach($post as $key => $val): if($key != "providerId") { $val = formValidate($val); $sqlE[] = "`$key`='$val'"; } endforeach; $sqlE = implode(",", $sqlE); $where = ' WHERE `id` = \''.$post['id'].'\''; $sql = $sql . $sqlE . $where; $query = mysql_query($sql); if($query){ return true; } } // }//end class And then use this function * INSIDE of another class *: function formValidate($string){ $string = trim($string); $string = mysql_real_escape_string($string); return $string; } // .. on $val. Why doesn't this work? if I write in a field of the form, it's not escaping anything at all. How can that be? * UPDATE * handler.php: if(isset($_GET['do'])){ if($_GET['do'] == "addLogin") { $addLogin = $db->addLogin($_POST); } if($_GET['do'] == "addProvider") { $addProvider = $db->addProvider($_POST); } if($_GET['do'] == "editProfile") { $editProfile = $db->editProfile($_POST); } if($_GET['do'] == "editProvider") { $editProvider = $db->editProvider($_POST); } } //end if isset get do ** The editProvider function works fine except for this :-) **

• Java Hibernate session delete of object

  - by user2535201

  I'm really struggling with hibernate sessions, I never have the result I expect when making a query on a modified session object. I think all my problems are related. The last one is the following : final Session iSession = AbstractDAO.getSessionFactory().openSession(); try { iSession.beginTransaction(); MyObject iObject = DAOMyObject.getInstance().get(iSession,ObjectId); iObject.setQuantity(0); //previously the quantity was different from zero DAOMyObject.getInstance().update(iSession,iObject); DAOMyObject.getInstance().deleteObjectWithZeroQuantities(iSession); iSession.getTransaction().commit(); } catch (final Exception aException) { iSession.getTransaction().rollback(); logger.error(aException.getMessage(), aException); throw aException; } finally { iSession.close(); } What I'm not getting is why the object is not deleted, since I'm modified it in the session, the query making the delete should find it. I had the same problem with creating an object with an incremental id in a session, then creating another one in the same session before the commit, with a select max(id)+1. But the session gets me the same number of id every time.

• Having trouble with php and ajax search function

  - by Andy

  I am still quite new to php/ajax/mysql. In anycase, I'm creating a search function which is returning properly the data I'm looking for. In brief, I have a mysql database set up. A php website that has a search function. I'm now trying to add a link to a mysql database search rather than just showing the results. In my search.php, the echo line is working fine but the $string .= is not returning anything. I'm just trying to get the same as the echo but with the link to the mysql php record. Am I missing something simple? //echo $query; $result = mysqli_query($link, $query); $string = ''; if($result) { if(mysqli_affected_rows($link)!=0) { while($row = mysqli_fetch_array($result,MYSQLI_ASSOC)) { echo '<p> <b>'.$row['title'].'</b> '.$row['post_ID'].'</p>'; $string .= "<p><a href='set-detail.php?recordID=".$row->post_ID."'>".$row->title."</a></p>"; } } else { echo 'No Results for :"'.$_GET['keyword'].'"'; }

• mysql php problem: no error message despite error_reporting(E_ALL) line

Instead I get a blank page after clicking the submit button. Do I have to do something differently to insert data?

• How do I set up a working GUEST USER account in Win XP Pro?

  - by user6501

  I have two user accounts within my WinXP Pro PC. One I'd like to erase. But I'd also like to setup a GUEST user account. I've already gotten 2-step instructions on how to get rid of the extraneous account: a) use an MS tool called delprof.msi b) manually delete the former users files in Documents & Settings. But I guess my original question was too complex -- kind of like a bill in Congress. So now I am just asking the final part of the question: How do I create a GUEST ACCOUNT -- then define what it will authorize/grant access to? i.e. internet browser(s), specific programs and files etc

• ISCSI sessions appear from nowhere

  - by Maraca

  Hi, I am using Win2008 32bit Ent. running in Hyper-V with 2 LUNs over ISCSI connection (this is a MS cluster with one LUN being quorum and second as a storage). In ISCSI - target - details I see multiple sessions from same target (currently 7), however I am not sure where they are coming from as I have only one virtual NIC on this server. Sure enough 2 LUNs appear 7 times each in device manager or in disk manager. On the cluster partner however, I do not see that problem. There is only one session per target. Installing MPIO makes only difference - I am getting 8 sessions instead of 7 once I reboot. Does any one know what can cause this behavior?

• JDBC with JSP fails to insert

  I am having some issues right now with JDBC in JSP. I am trying to insert username/pass ext into my MySQL DB.

• ORDERBY "human" alphabetical order using SQL string manipulation

  - by supertrue

  I have a table of posts with titles that are in "human" alphabetical order but not in computer alphabetical order. These are in two flavors, numerical and alphabetical: Numerical: Figure 1.9, Figure 1.10, Figure 1.11... Alphabetical: Figure 1A ... Figure 1Z ... Figure 1AA If I orderby title, the result is that 1.10-1.19 come between 1.1 and 1.2, and 1AA-1AZ come between 1A and 1B. But this is not what I want; I want "human" alphabetical order, in which 1.10 comes after 1.9 and 1AA comes after 1Z. I am wondering if there's still a way in SQL to get the order that I want using string manipulation (or something else I haven't thought of). I am not an expert in SQL, so I don't know if this is possible, but if there were a way to do conditional replacement, then it seems I could impose the order I want by doing this: delete the period (which can be done with replace, right?) if the remaining figure number is more than three characters, add a 0 (zero) after the first character. This would seem to give me the outcome I want: 1.9 would become 109, which comes before 110; 1Z would become 10Z, which comes before 1AA. But can it be done in SQL? If so, what would the syntax be? Note that I don't want to modify the data itself—just to output the results of the query in the order described. This is in the context of a Wordpress installation, but I think the question is more suitably an SQL question because various things (such as pagination) depend on the ordering happening at the MySQL query stage, rather than in PHP.

• How can I make PHP scripts timeout gracefully while waiting for long-running MySQL queries?

  - by Mark B

  I have a PHP site which runs quite a lot of database queries. With certain combinations of parameters, these queries can end up running for a long time, triggering an ugly timeout message. I want to replace this with a nice timeout message themed according to the rest of my site style. Anticipating the usual answers to this kind of question: "Optimise your queries so they don't run for so long" - I am logging long-running queries and optimising them, but I only know about these after a user has been affected. "Increase your PHP timeout setting (e.g. set_time_limit, max_execution_time) so that the long-running query can finish" - Sometimes the query can run for several minutes. I want to tell the user there's a problem before that (e.g. after 30 seconds). "Use register_tick_function to monitor how long scripts have been running" - This only gets executed between lines of code in my script. While the script is waiting for a response from the database, the tick function doesn't get called. In case it helps, the site is built using Drupal (with lots of customisation), and is running on a virtual dedicated Linux server on PHP 5.2 with MySQL 5.

• Any Microsoft SQL Server 2008 licensing restrictions on usage?

  - by ryrobes

  Does Microsoft have any problems with HOW I USE SQL Server Standard Edition 2008? I plan on using it to aggregate my clients various data sources and report on them (using the whole stack - SSIS, DB, Analysis Services and Reporting Services) via the web. I don't want to run into any issues with being accused of "re-selling" services / features when I'm not allowed to, etc. In essence, I'm charging people to build them solutions based on / using MY licensed copy and then giving them access to the final products. (reports, etc) It seems straightforward enough - but who knows with MS... (BTW, Licensed by processor / not CAL)

• Dialog boxes font is missing in Windows 7

  - by forgetso

  About 3 years ago I messed up my laptop with some virus removal software. It's obviously changed the registry settings and the text in dialogue boxes in the control panel, run box, etc. is the wrong size. See image:http://i.stack.imgur.com/SlFFU.jpg I've tried changing the MS Shell Dlg registry values to different fonts and restarting. I've made sure that I have the fonts SSERIFE.FON and SERIFE.FON on my system and that they are correctly referenced in the registry. Does anyone know how to fix this? I'd like to be able to see all of the options in the dialog boxes! Cheers

• How can I open a file as read-only from Windows Explorer?

  - by Daniel Daranas

  Is there an easy way to open a file as read-only from Windows Explorer? My inmediate interest is in a Microsoft Access file. I am doing some sanity checks in old MS Access databases and I see that their date is automatically updated when I open them. I don't like this, since it will look like all the old files have been modified today. I am working with Windows XP. Update: As Yoda said, "Do, or do not. There is no try." In my case, it was "do not". I ended up copying the entire (big) folder tree to MyDocuments, and then opening all the databases from there.

• setfirstresult & setmaxresult in child collection

  - by Miguel Marques

  I have and entity lets call it Entity, and a Child collection Children. I have a screen where the user has the Entity information, and a list with the Children collection, but that collection can be get very big, so i was thinking about using paging: get the first 20 elements, and lazy load the next only if the user explicitly presses the next button. So i created in the Entity Repository a function with this signature: IEnumerable<Child> GetChildren(Entity entity, int actualPage, int numberOfRecordsPerPage) I need to use the setfirstresult and setmaxresult, not in the Agregate root Entity, but in the child collection. But when i use those two configurations, they allways refer to the entity type of the HQL/Criteria query. Other alternative would be to create a HQL/Criteria query for the Child type, set the max and first result, then filter the ones who are in the Entity Children collection (by using subquery). But i wasn't able to do this filter. If it was a bidirectional association (Child refering the parent Entity) it would be easier. Any suggestions? Any

Is there any way with eTrust ITM 8.1 to export the different policies as csv, pdf ... whatever? I really dont want to do that manually (that would mean one print screen after the other ;-) ) Thank you very much. grub

• Is there a way to create a custom installer package to do batch installs of a bunch of programs at o

  - by user37860

  Basically I want to create a file which will automatically install a bunch of files without having to manually install each of them (i.e. Flash, Adobe Reader, MS Office, etc.). I'm guessing the easiest way to do this would be to create a batch file but I don't have much experience with the scripting side of things. I remember seeing a website at one point that would do this sort of thing for you but I'm not sure if that could be used offline or not. Thanks in advance...just looking to make things a bit more streamlined on new builds without the costs associated with imaging software. Thanks!
