• Why might SQL execute more quickly on SQL Server 2000 when NOT using a stored procedure?

  - by Kofi Sarfo

  I could see nothing wrong with the execution plan. Besides, as I understand it, SQL Server 2000 extended many of the performance benefits of stored procedures to all SQL statements by recognising new T-SQL statements against T-SQL statements of existing execution plans (by retaining execution plans for all SQL statements in the procedure cache, not just stored procedure execution plans) It's a fairly straight forward SELECT statement with sensible table joins, no transactions included or linked servers being referenced within the query and WITH (NOLOCK) table hints applied. The stored procedure was created by dbo and the user has all the necessary permissions. So my question is this: What are the likely reasons for a query to take only a few seconds to run but then take several minutes when identical T-SQL is run via a stored procedure?

• How to register data for validation using RegisterForEventValidation in asp.net

  - by rocksolid

  I would like to know the method of using RegisterForEventValidation in asp.net My problem is this. If I enable eventvalidation, then changing the controls using javascript and then posting the information back to the server later on throws up an error. But If I disable event validation, the data present/selected in the controls is not available in the event handlers in code behind. So, how should one resolve such issues? Also, are there are any good articles that explain the issue and a resolution in detail? Tried googling. Came across many articles. But nothing that matched my expectations. Thanks!

• Simple github fetch/merge not pulling in remote branch?

  - by chum of chance

  I have a project I forked on github to my repository. I made changes on the "experiment" branch of the project the committed the project to my fork. If you go to my branch on Github you can see the that the experiment branch was correctly committed. I would like to merge the experiment branch with the original repo (which I have rights to). I issued the following commands: git clone [email protected]:originalrepo/theproject.git git checkout -b experiment origin/experiment cd theproject git remote add experiment [email protected]:chumofchance/theproject.git git fetch experiment git merge experiment "Already up to date" However, when I view the project in explorer, it appears that nothing has changed. Am I screwing something up in regards to fetching the experiment branch (vs the master branch)?

• Scala type system : basic type mismatch

  - by SiM

  I have a basic type system type mismatch problem: I have a class with a method def Create(nodeItem : NodeItem) = {p_nodeStart.addEndNode(nodeItem)} where p_nodeStart is NodeCache class NodeCache[END_T<:BaseNode] private(node: Node) extends BaseNode { def addEndNode(endNode : END_T) = {this.CACHE_HAS_ENDNODES.Create(endNode)} and the error its giving me is: error: type mismatch; found : nodes.NodeItem required: Nothing def Create(nodeItem : NodeItem) = {p_nodeStart.addEndNode(nodeItem)} while the NodeCache is defined as object NodeTrigger { def Create() { val nodeTimeCache = NodeCache.Create[NodeItem](node) and in object NodeCache object NodeCache { def Create[END_T<:BaseNode]() { val nodeCache = new NodeCache[END_T](node); Any ideas, how to fix the error?

• SQL finding members who are not friends of another member

  - by thedirktastik

  I'm struggling to find a query which will return members who aren't friends of a certain member. Here is the layout of my tables: member_login: MemberID, email, password member_info: memberID, first_name, last_name member_friends: friendID, req_member, req_date, app_member, app_date, date_deactivated I tried to use NOT IN to run a query that would return the opposite of friends but nothing I try seems to be working. Here's what I thought would work: SELECT Mi.First_Name, Mi.Last_Name FROM Member_Info Mi WHERE Mi.Memberid NOT IN( SELECT Mi.Memberid, Mi.First_Name, Mi.Last_Name FROM Member_Info Mi, Member_Login Ml, Member_Friends Mf WHERE Mi.Memberid = Ml.Memberid AND (Mi.Memberid = Mf.Req_Member AND Mf.App_Member = 1 OR Mi.Memberid = Mf.App_Member AND Mf.Req_Member =1) AND Ml.Date_Deactivated <= 0 AND Mf.App_Date > 0 ); Any ideas?

• SQL Having Clause

  - by Wally

  I'm trying to get a stored procedure to work using the following syntax: select count(sl.Item_Number) as NumOccurrences from spv3SalesDocument as sd left outer join spv3saleslineitem as sl on sd.Sales_Doc_Type = sl.Sales_Doc_Type and sd.Sales_Doc_Num = sl.Sales_Doc_Num where sd.Sales_Doc_Type='ORDER' and sd.Sales_Doc_Num='OREQP0000170' and sl.Item_Number = 'MCN-USF' group by sl.Item_Number having count (distinct sl.Item_Number) = 0 In this particular case when the criteria is not met the query returns no records and the 'count' is just blank. I need a 0 returned so that I can apply a condition instead of just nothing. I'm guessing it is a fairly simple fix but beyond my simple brain capacity. Any help is greatly appreciated. Wally

• MongoDB C# Driver Unable to Find by Object ID?

  - by Hery

  Using MongoDB C# driver (http://github.com/samus/mongodb-csharp), seems that I'm unable to get the data by ObjectId. Below the command that I'm using: var spec = new Document { { "_id", id } }; var doc = mc.FindOne(spec); I also tried this: var spec = new Document { { "_id", "ObjectId(\"" + id + "\")" } }; var doc = mc.FindOne(spec); Both return nothing. Meanwhile, if I query it from the mongo console, it returns the expected result. My question is, does that driver actually support the lookup by ObjectId? Thanks..

• Problem trying to move a CCSprite circle in Cocos2d

  - by thyrgle

  Hi, So I am trying to move a CCSprite (which has the picture of a circle and is 32 by 32 pixels) with ccTouchesBegan. I have tried the following: -(void) ccTouchesBegan:(UITouch *)touch withEvent:(UIEvent *)event { CGPoint location = [touch locationInView:touch.view]; if ((location.x <= L1Circle1.position.x + 32 && location.x >= L1Circle2.position.x - 32) && (location.y <= L1Circle1.position.y + 32 || location.y >= L1Circle2.position.y - 32)) { L1Circle1.position = ccp(location.x, location.y); } } But, when I touch the screen in the simulator nothing happens... What am I doing wrong?

• Drupal Imagecache not working

  - by stef

  I created an Imagecache setting that just resizes to 125px wide. First issue is that the preview image is 404. Then I want to print out an image via <?php print theme('imagecache', 'imported_image', $node->picture, 'test', 'test', $attributes); ?> 'imported_image' being the preset and $node-picture is a correct path. The html prints out ok but the path it's trying load the image from does not exist. In sites/default/files/imagecache there is no folder with the name of the preset. Flushing the preset does nothing. The imagecache folder is writeable by everyone. This is on MAMP. Anyone know what the issue could be?

• Creating share programmatically fails with error 9

  - by Christopher

  Directory.CreateDirectory("C:\MyTestShare") Dim managementClass As New ManagementClass("Win32_Share") Dim inParams As ManagementBaseObject = managementClass.GetMethodParameters("Create") inParams.Item("Description") = "My Files Share" inParams.Item("Name") = "My Files Share" inParams.Item("Path") = "C:\MyTestShare" inParams.Item("Type") = 0 If (DirectCast(managementClass.InvokeMethod("Create", inParams, Nothing).Properties.Item("ReturnValue").Value, UInt32) <> 0) Then Throw New Exception("Unable to share directory.") End If I am using the following code to set up a share, but I am always getting a return value of 9 which means invalid name. I am passing a string and have tried to use an explicit string and I still get error 9. I am creating the share remotely rather than on local machine however. Not sure if that matter.

• How can I programmatically read a Adobe DRM'd Epub?

  - by DEzra

  I am writing an ebook reader that supports the epub format (i have the parsing of open epub working), but I would like to support the reading of Adobe DRM locked epubs. I have read through the Adobe digital editions site (faq and support pages) and googled, but alas as yet I have not found any docs on the API to: authorise the PC using the user's Adobe ID credentials and decrypt the epub for parsing by my app. Does anyone have any pointers to docs or APIs? I would prefer APIs in Python, C++. But any API is better than nothing ;-) UPDATE1: I am writing my app on Desktops (linux, mac and windows). UPDATE2: Just to be clear, I am assuming that user has paid for the book legitimately and so does have an Adobe ID. I don't want to crack the DRM, just allow the user to read their books that they bought.

• LINQ to SQL SubmitChangess() progress

  - by Emir

  I'm using LINQ to SQLto import old DBF files into MSSQL. I'm reading all rows and adding them to database using ctx.MyTable.InsertOnSubmit(row) After reading phase is completed I have around 100 000 pending inserts. ctx.SubmitChanges() naturally is taking a long time. Is there any way to track progress of the ctx.submitchanges()? Can ctx.Log somehow be used for this purpose? Update: Is it possible to use ctx.GetChangeSet().Inserts.Count and track insert statements using the Log? Dividing ctx.SubmitChanges() into smaller chunks is not working for me, because I need transaction, all or nothing. Update 2: I've found nice class ActionTextWriter using which I will try to count inserts. http://damieng.com/blog/2008/07/30/linq-to-sql-log-to-debug-window-file-memory-or-multiple-writers

• Check if hydrated doctrine result is NULL

  - by iggnition

  Hi, I'm trying to check if a result in my DQL is NULL. I got the following DQL query: $q = self::createQuery("l") ->select('i.*, s.aantal, m.naam, c.cat_naam, a.app_id') ->from('InstalledBase i, i.Spare s, i.Apparaat a, a.Categorie c, a.Merk m') ->execute(); return $q; Now i want to check if the s.aantal is NULL so i do: if(is_null($installedbase->Spare->spare_id)) when the variable is NOT null everything works, but when it is actually NULL i get a E notice message: Notice: Trying to get property of non-object in \installedbase\templates\_index.php on line 29 It does see that it is null though because the if condition is executed. Weird thing is i'm doing the exact same thing on another page where it works no problem. But i must be doing something wrong or stupid since those messages generally don't show for nothing. So can anybody explain this to me? :)

• .attr("disabled", "disabled") problem

  - by meo

  i have this function where basically add and remove the disabled attribute form a input field: $(bla).click(function(){ if (something) { console.log($target.prev("input")) // gives out the right object $target.toggleClass("open").prev("input").attr("disabled", "disabled"); }else{ $target.toggleClass("open").prev("input").removeAttr("disabled"); //this works } }) the removeAttr works fine but when i need to add the disabled again it does just nothing. My console.log is triggering (and giving me back the right input field) so I'm sure my that my if statement works. But if i inspect the DOM with firebug the disabled attribute does not appear. can someone help me? PS: please don't focus on the function or the if statement itself, works fine its just that attr that dies not work for disabled...

• jQuery and CodeIgniter AJAX with JSON not working

  - by thedp

  Hello, I trying to make my first AJAX with JSON call using jQuery and CodeIgniter. But for some weird reason it's not working. The jQuery code: var item = "COOL!"; $.post("http://192.168.8.138/index.php/main/test", { "item" : item }, function(data){ alert(data.result); }, "json"); The CodeIgniter code: <?php class main extends Controller { function test() { $item = trim($this->input->post('item')); $array = array('result' => $item); echo json_encode($array); } } ?> I tried to access the http://192.168.8.138/index.php/main/test page manually and it seems to be working, I got: {"result":""} I also tried to use Firebug to see XMLHttpRequest but saw nothing. I have no idea what am I doing wrong... Need help really badly. Thank you.

• How do I make a universal iPhone / iPad application that programmatically uses UISplitViewController

  - by arash13

  I couldn't find a good answer anywhere to this. I am using a UINavigationController for my iPhone app, with everything is generated programmatically, nothing in Interface Builder. I am trying to port my app to iPad, using a UISplitViewController and my existing UINavigationController, but I am not sure where I should have the logic of my program separating the view controllers for iPhone or iPad. Do I set up my main file to use a different app delegate or do I use the same app delegate and have the user interface conditionally set up within it? Besides this, whenever I try to compile my app on the simulator it does not recognize the UISplitViewController or even the condition in which I check if the class exists. Can please someone put me in the right direction, remembering that I am not using any xibs?

• datagridview winform tag only brings back the first row value

  - by jvcoach23

  I'm using visual studio 2008. I have a datagridview in a winform. I've bound to it using an object Private Sub LoadAllCampers() Dim Os As List(Of LE.Camper) = Nothing Dim Oc As New LE.Camper_Controller Os = Oc.GetCamperData(0) With Me.dgResults .DataSource = Os End With CamperBindingSource.DataSource = Os End Sub I have a tag setup on the ID property within the Camper class. when i double click on a row in teh datagridview, i do a me.dgResults.tag and it always shows the first rows ID value. If i change the ordering within the class, it will display a different value, but it's always the first value in the datagridview. I'm missing something simple to get this working.. just don't know what it is. Hopefully someone can spare a minute.

• jQuery Custom Gallery and jCarousel problem

  - by steve

  Active site can be seen here: http://www.studioimbrue.com/index2.php There are currently two small problems with the coding. First: when the page loads and you attempt to click on one of the large images to advance, nothing happens. Once a thumbnail is clicked, the click functionality of the large image comes available. I'm trying to fix it so when the page loads, the user can just start clicking the large image. Second: when an image is clicked, the thumbnail highlight changes. The only problem there is once it gets past 4, the "current" thumbnail needs to be seen, thus the carousel should go to that one. Right now the code for that is nextThumb.closest('.thumbscontainer').jcarousel('next'); but that makes it scroll every time you click. Thanks for any help

• How can I find out which version of emacs introduced a function?

  - by Chris R

  I want to write a .emacs that uses as much of the mainline emacs functionality as possible, falling back gracefully when run under previous versions. I've found through trial and error some functions that didn't exist, for example, in emacs 22 but now do in emacs 23 on the rare occasion that I've ended up running my dotfiles under emacs 22. However, I'd like to take a more proactive approach to this, and have subsets of my dotfiles that only take effect when version = <some-threshold> (for example). The function I'm focusing on right now is scroll-bar-mode but I'd like a general solution. I have not seen a consistent source for this info; I've checked the gnu.org online docs, the function code itself, and so far nothing. How can I determine this, without keeping every version of emacs I want to support kicking around?

• How to update control state in asp.net/ajax?

  - by darth_alexious

  I'm trying to update certain controls according to a selection in a dropdown list. For example, in the "selectedIndexChanged" event of a dropDownList, if a user selects the value "sport-car" the text box "payload" is disabled and the textbox "max speed" is enabled. private sub dropDownList1_SelectedIndexChanged(byval sender as object, byval e as eventargs) handles dropDownList1.SelectedIndexChanged If dropDownList1.selectedValue = "sport-car" then textBox_payLoad.enabled = false textBox_maxSpeed.enabled = true end if end sub When I'm doing something like this, the controls aren't enabled/disabled, even the event (wich I've added a breakpoint) seems not to be raised (sometimes several time after it is raised). Also, when the instructions in the condition is executed, nothing changes. What am I doing wrong? Maybe this is a very easy issue, but I'm a begginer in MS Visual Web Developer.

• Bind selected value on combobox to view model

  - by Shaggy

  Hi, I have my silverlight app which pulls data into a datagrid from a view model. The vm is exposed via Mef. I also have a details grid which has comboboxes. The vm also contains the data to populate the combobox values. Upon first load, everything works fine and the selected items on te comboboxes are correct and I can select alternative values. However, if I sort my main data grid (allow sort=true) then I find the binding for selected value on the comboboxes dissapear. The combobox is still populated with data but nothing is selected. Has anyone come across this issue before? I am unsure how to solve this one. Thanks

• How can I find out if an data- attribute is set to an empty value?

  - by Stephan Wagner

  Is there a way to find out if an data- attribute is set to an empty value or if it is not set at all? See this fiddle example (Check the console when clicking on the elements): http://jsfiddle.net/StephanWagner/yy8qvwfp/ <div onclick="console.log($(this).attr('data-test'))">undefined</div> <div data-test="" onclick="console.log($(this).attr('data-test'))">empty</div> <!-- this one will also return an empty value --> <div data-test onclick="console.log($(this).attr('data-test'))">null</div> <div data-test="value" onclick="console.log($(this).attr('data-test'))">value</div> Im having the issue with the third example. I need to know if the attribute actually is set to an empty value or if it is not set at all. Is that actually possible? EDIT: The reason I'm asking is that I'm updating content with the attributes value, so data-test="" should update the content to an empty value, but data-test should do nothing at all

• C++: what regex library should I use?

  - by Stéphane

  I'm working on a commercial (not open source) C++ project that runs on a linux-based system. I need to do some regex within the C++ code. (I know: I now have 2 problems.) QUESTION: What libraries do people who regularly do regex from C/C++ recommend I look into? A quick search has brought the following to my attention: 1) Boost.Regex (I need to go read the Boost Software License, but this question is not about software licenses) 2) C (not C++) POSIX regex (#include <regex.h>, regcomp, regexec, etc.) 3) http://freshmeat.net/projects/cpp_regex/ (I know nothing about this one; seems to be GPL, therefore not usable on this project) Thanks.
