  • broken SQL 2008 SP1 Web Edition (can not login with SSMS)

    - by gerryLowry
    Scenario: My installation of SQL Server 2008 Web Edition SP1 was working properly. Since I've recently joined Microsoft's Website Spark*, I removed SQL2008 and installed SQL 2008 again using my Website Spark edition and license from the MSDN download site. Next, I updated SQL 2008 to SP1 (this is required because I'm running Windows 2008 Server R2 Web edition). When I launch SSMS (SQL Server Management Studio), "User name" is "myhost\Administrator" and is greyed out so it can not be changed. When I installed my Website Spark version, I did not include "myhost\Administrator" when I was configuring SQL 2008 service accounts. Instead I created an administrator account "myhost\mySQLaccount". ERROR MESSAGE: Connect to Server (X) Cannot connect to (local) Additional information: Login failed for user 'myhost'Admistrator' (Microsoft SQL Server, Error: 18456) I tried to use the SQL Server Configuration Manager to correct this problem but could not find any useful way to fix this issue. How to I fix this problem? Connect to Server ... Server type: Database Engine Server name: (local) Authentication: Windows Authentication Please advise. Thank you.

  • Why do Firefox and Opera ignore max-width inside of display: table-cell?

    - by brad
    The following code displays correctly in Chrome or IE (the image is 200px wide). In Firefox and Opera the max-width style is ignored completely. Why does this happen and is there a good work around? Also, which way is most standards compliant? Note One possible work around for this particular situation is to set max-width to 200px. However, this is a rather contrived example. I'm looking for a strategy for a variable width container. <!doctype html> <html> <head> <style> div { display: table-cell; padding: 15px; width: 200px; } div img { max-width: 100%; } </style> </head> <body> <div> <img src="http://farm4.static.flickr.com/3352/4644534211_b9c887b979.jpg" /> <p> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec facilisis ante, facilisis posuere ligula feugiat ut. Fusce hendrerit vehicula congue. at ligula dolor. Lorem ipsum dolor sit amet, consectetur adipiscing elit. leo metus, aliquam eget convallis eget, molestie at massa. </p> </div> </body> </html> [Update] As stated by mVChr below, the w3.org spec states that max-width does not apply to inline elements. I've tried using div img { max-width: 100%; display: block; }, but it does not seem to correct the issue.

  • .NET Hashtable - "Same" key, different hashes

    - by Simon Lindgren
    Is it possible for two .net strings to have different hashes? I have a Hashtable with amongst others the key "path". When I loop through the elements in the table to print it, i can see that the key exists. When trying to looking it up however, there is no matching element. Debugging suggests that the string I'm looking for has a different hash than the one I'm supplying as the key. This code is in a Castle Monorail project, using brail as a view engine. The key I'm looking for is inserted by a brail line like this: UrlHelper.Link(node.CurrentPage.LinkText, {@params: {@path: "/Page1"}}) Then, in this method (in a custom IRoutingRule): public string CreateUrl(System.Collections.IDictionary parameters) { PrintDictionaryToLog(parameters); string url; if (parameters.Contains("path")) { url = (string)parameters["path"]; } else { return null; } } The key is printed to the log, but the function returns null. I didn't know this could even be a problem with .net strings, but I guess this is some kind of encoding issue? Oh, and this is running mono.

  • Control Oracle Forms with outside program

    - by user256893
    I work at a company that uses the Forms based Oracle 11i. A lot of employees complain of the redundancy of data entry and I want to write a program that will ease some of that pain since all attempts to ask IT to do it have failed. The problem is, since Oracle Forms are Java based there are no "controls" as there would be on say a windows application or an HTML based form. Does anyone know of a way to tell the PC to (example only) click edit field 3 on the RMA creation form and then enter the data? The only way I can programmatically navigate Oracle is with hotkeys and it's very unreliable. I'm not concerned about the language or learning a new application to resolve this issue. I currently know (elementary to Intermediate levels) Java, VB.NET and will be taking C++ in school. Is there a tool, bridge, element spy of some sort that will allow me to send commands to elements on the forms? edit APC sez: Oracle Forms over the web run as a Java applet. I mention this because it may be relevant to your responses.

  • jquery-sortable using behavior of a linkedlist

    - by BabaBooey
    I suspect I'm not looking at this issue in the right way so here goes. I have essentially a LinkedList of data on a web page (http://en.wikipedia.org/wiki/Linked_list) that I'd like to manipulate using traditional Linked List behavior (i.e. just updating the reference/id of the "next" object) for performance reasons. Where this gets a bit tricky is I'd ideally like to use Jquery's sortable to do this. Like the user would drag something up/down and I could just do an Ajax call to the server with the id of the object that moved and the new parent id of that object (and then behind the scenes I could figure out how to reconnect things..maybe need more data than that...). But every example I've seen where sortable is used they were sending the whole re-indexed list to the database to update which seems unnecessary to me. With a linked list to change an element's "index" I only need to make 3 updates which depending on the size of the list could be a big performance savings. Anyone have an example of what I'm trying to do...am I too far in left field?

  • Catching 'Last Record' in Coldfusion for IE javascript bug

    - by Simon Hume
    I'm using ColdFusion to pull UK postcodes into an array for display on a Google Map. This happens dynamically from a SQL database, so the numbers can range from 1 to 100+ the script works great, however, in IE (groan) it decides to display one point way off line, over in California somewhere. I fixed this issue in a previous webapp, this was due to the comma between each array item still being present at the end. Works fine in Firefox, Safari etc, but not IE. But, that one was using a set 10 records, so was easy to fix. I just need a little if statement to wrap around my comma to hide it when it hits the last record. I can't seem to get it right. Any tips/suggestions? here is the line of code in question: var address = [<cfloop query="getApplicant"><cfif getApplicant.dbHomePostCode GT ""><cfoutput>'#getApplicant.dbHomePostCode#',</cfoutput></cfif> </cfloop>]; Hopefully someone can help with this rather simple request. I'm just having a bad day at the office!

  • Scope of This JavaScript Variable

    - by dkris
    I have a question and an issue wrt the code below: My question is what is the scope of the variable loaded here. The reason why i ask this is the onload="if(loaded==1)inittextarea() code is working fine on Firefox and not IE8. Why is this happening? Is there something specific i need to do here? Or is it not a valid practice? <html> <head> <title>Some Page</title> <link rel="stylesheet" href="../css/default.css" type="text/css"> <script type="text/javascript"> var loaded = 0; /*Point of interest*/ function jsLoaded() { loaded =1; } </script> <script type="text/javascript"> function inittextarea() { alert("test") tinyMCE.init({ elements : "content", theme : "advanced", readonly : true, mode : "exact", theme : "advanced", readonly : true, setup : function(ed) { ed.onInit.add(function() { tinyMCE.activeEditor.execCommand("mceToggleVisualAid"); }); } }); } </script> <script src="../js/tiny_mce/tiny_mce.js" onload="jsLoaded()" type="text/javascript"></script> </head> <body onload="if(loaded==1)inittextarea()"><!--Works on Firefox only--> *Usual stuff* </body></html> Any pointers please?

  • How to get debugging of an App Engine application working?

    - by Chris Lacy
    I've got 10+ years in C/C++, and it appears Visual Studio has spoilt me during that time. In Visual Studio, debbuging issimple: I just add a breakpoint to a line of code, and as soon as that code is executed, my breakpoint triggers, at which point I can view a callstack, local/member variables, etc. I'm trying to achieve this functionality under App Engine. I assume that is possible? All the searching I've done to this point has led me to using Pydev in Eclipse. As best I can tell, I am successfully launching my simple 'hello world' program in Debug mode. But the IDE doesn't even seem to have an option to set a breakpoint? I must be missing something. I've googled long and hard about this, but am having no luck. Most results trace back to the same old threads that don't deal directly with my issue. Can anyone shed some light on how you get basic debugging setup using Pydev/Eclipse with App Engine? Alternatively, if there's an easier way to debug App Engine than using Pydev/Eclipse, I'd love to hear about it. Thanks in advance.

  • Visual Studio 2008: Can't connect to known good TFS 2010 beta 2

    - by p.campbell
    A freshly installed TFS 2010 Beta 2 is at http://serverX:8080/tfs. A Windows 7 developer machine with VS 2008 Pro SP1 and the VS2008 Team Explorer (no SP). The TFS 2008 Service Pack 1 didn't work for me - "None of the products that are addressed by this software update are installed on this computer." The developer machine is able to browse the TFS site at the above URL. The Issue is around trying to add the TFS server into the Team Explorer window in Visual Studio 2008. Here's a screenshot showing the error: unable to connect to this Team Foundation Server. Possible reasons for failure include: The Team Foundation Server name, port number or protocol is incorrect. The Team Foundation Server is offline. Password is expired or incorrect. The TFS server is up and running properly. Firewall ports are open, and is accessible via the browser on the dev machine!! larger image Question: how can you connect from VS 2008 Pro to a TFS 2010 Beta 2 server? Resolution Here's how I solved this problem: installed VS 2008 Team Explorer as above. re-install VS 2008 Service Pack 1 when adding a TFS server to Team Explorer, you MUST specify the URL as such: http://[tfsserver]:[port]/[vdir]/[projectCollection] in my case above, it was http://serverX:8080/tfs/AppDev-TestProject you cannot simply add the TFS server name and have VS look for all Project Collections on the server. TFS 2010 has a new URL (by default) and VS 2008 doesn't recognize how to gather that list.

  • Doctrine 1.2: How do i prevent a contraint from being assigned to both sides of a One-to-many relati

    - by prodigitalson
    Is there a way to prevent Doctrine from assigning a contraint on both sides of a one-to-one relationship? Ive tried moving the definition from one side to the other and using owning side but it still places a constraint on both tables. when I only want the parent table to have a constraint - ie. its possible for the parent to not have an associated child. For example iwant the following sql schema essentially: CREATE TABLE `parent_table` ( `child_id` varchar(50) NOT NULL, `id` integer UNSIGNED NOT NULL auto_increment, PRIMARY KEY (`id`) ); CREATE TABLE `child_table` ( `id` integer UNSIGNED NOT NULL auto_increment, `child_id` varchar(50) NOT NULL, PRIMARY KEY (`id`), UNIQUE KEY (`child_id`), CONSTRAINT `parent_table_child_id_FK_child_table_child_id` FOREIGN KEY (`child_id`) REFERENCES `parent_table` (`child_id`) ); However im getting something like this: CREATE TABLE `parent_table` ( `child_id` varchar(50) NOT NULL, `id` integer UNSIGNED NOT NULL auto_increment, PRIMARY KEY (`id`), CONSTRAINT `child_table_child_id_FK_parent_table_child_id` FOREIGN KEY (`child_id`) REFERENCES `child_table` (`child_id`) ); CREATE TABLE `child_table` ( `id` integer UNSIGNED NOT NULL auto_increment, `child_id` varchar(50) NOT NULL, PRIMARY KEY (`id`), UNIQUE KEY (`child_id`), CONSTRAINT `parent_table_child_id_FK_child_table_child_id` FOREIGN KEY (`child_id`) REFERENCES `parent_table` (`child_id`) ); I could just remove the constraint manually or modify my accessors to return/set a single entity in the collection (using a one-to-many) but it seems like there should built in way to handle this. Also im using Symfony 1.4.4 (pear installtion ATM) - in case its an sfDoctrinePlugin issue and not necessarily Doctrine itself.

  • Tableview not updating correctly after adding person

    - by tazboy
    I have to be missing something simple here but it escapes me. After the user enters a new person to a mutable array I want to update the table. The mutable array is the datasource. I believe my issue lies within cellForRowAtIndexPath. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { TextFieldCell *customCell = (TextFieldCell *)[tableView dequeueReusableCellWithIdentifier:@"TextCellID"]; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"cell"]; if (indexPath.row == 0) { if (customCell == nil) { NSArray *nibObjects = [[NSBundle mainBundle] loadNibNamed:@"TextFieldCell" owner:nil options:nil]; for (id currentObject in nibObjects) { if ([currentObject isKindOfClass:[TextFieldCell class]]) customCell = (TextFieldCell *)currentObject; } } customCell.nameTextField.delegate = self; cell = customCell; } else { if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"cell"]; cell.textLabel.text = [[self.peopleArray objectAtIndex:indexPath.row-1] name]; NSLog(@"PERSON AT ROW %d = %@", indexPath.row-1, [[self.peopleArray objectAtIndex:indexPath.row-1] name]); NSLog(@"peopleArray's Size = %d", [self.peopleArray count]); } } return cell; } When I first load the view everything is great. This is what prints: PERSON AT ROW 0 = Melissa peopleArray's Size = 2 PERSON AT ROW 1 = Dave peopleArray's Size = 2 After I add someone to that array I get this: PERSON AT ROW 1 = Dave peopleArray's Size = 3 PERSON AT ROW 2 = Tom peopleArray's Size = 3 When I add a second person I get: PERSON AT ROW 2 = Tom peopleArray's Size = 4 PERSON AT ROW 3 = Ralph peopleArray's Size = 4 Why is not printing everyone in the array? This pattern continues and it only ever prints two people, and it's always the last two people. What the heck am I missing?

  • Aggregating / Collecting AJAX requests

    - by Ganesh Shankar
    I have situation where a user can manipulate a large set of data (presented in a table) by using a bunch of filters represented as checkboxes. The page is AJAXed up so the user doesn't have to wait for a full page refresh every time they click a filter. The way it's currently implemented is by having an event handler watch all the checkboxes and request filtered data from the server when a click event is triggered. This works fine. However, there is a usability & performance issue with doing it this way. For example, if a user clicks 6 checkboxes, 6 AJAX requests are triggered and they all come back at various intervals causing the page to be updated 6 times. This will most probably annoy the user and seems rather inefficient. I want to put some kind of timeout on the event handler to do something like this: "Wait for 1 second and if there are no more filters clicked trigger the AJAX request". However, at the moment I've only been able to delay all 6 requests by 1 second. I'm not sure how to aggregate / collect the filter info into 1 AJAX request. Any suggestions would be greatly appreciated!

  • What is causing my HTTP server to fail with "exit status -1073741819"?

    - by Keeblebrox
    As an exercise I created a small HTTP server that generates random game mechanics, similar to this one. I wrote it on a Windows 7 (32-bit) system and it works flawlessly. However, when I run it on my home machine, Windows 7 (64-bit), it always fails with the same message: exit status -1073741819. I haven't managed to find anything on the web which references that status code, so I don't know how important it is. Here's code for the server, with redundancy abridged: package main import ( "fmt" "math/rand" "time" "net/http" "html/template" ) // Info about a game mechanic type MechanicInfo struct { Name, Desc string } // Print a mechanic as a string func (m MechanicInfo) String() string { return fmt.Sprintf("%s: %s", m.Name, m.Desc) } // A possible game mechanic var ( UnkillableObjects = &MechanicInfo{"Avoiding Unkillable Objects", "There are objects that the player cannot touch. These are different from normal enemies because they cannot be destroyed or moved."} //... Race = &MechanicInfo{"Race", "The player must reach a place before the opponent does. Like \"Timed\" except the enemy as a \"timer\" can be slowed down by the player's actions, or there may be multiple enemies being raced against."} ) // Slice containing all game mechanics var GameMechanics []*MechanicInfo // Pseudorandom number generator var prng *rand.Rand // Get a random mechanic func RandMechanic() *MechanicInfo { i := prng.Intn(len(GameMechanics)) return GameMechanics[i] } // Initialize the package func init() { prng = rand.New(rand.NewSource(time.Now().Unix())) GameMechanics = make([]*MechanicInfo, 34) GameMechanics[0] = UnkillableObjects //... GameMechanics[33] = Race } // serving var index = template.Must(template.ParseFiles( "templates/_base.html", "templates/index.html", )) func randMechHandler(w http.ResponseWriter, req *http.Request) { mechanics := [3]*MechanicInfo{RandMechanic(), RandMechanic(), RandMechanic()} if err := index.Execute(w, mechanics); err != nil { http.Error(w, err.Error(), http.StatusInternalServerError) } } func main() { http.HandleFunc("/", randMechHandler) if err := http.ListenAndServe(":80", nil); err != nil { panic(err) } } In addition, the unabridged code, the _base.html template, and the index.html template. What could be causing this issue? Is there a process for debugging a cryptic exit status like this?

  • Has anyone used Ant4Eclipse with Project Lombok?

    - by gmcnaughton
    Has anyone successfully used Ant4Eclipse (http://www.ant4eclipse.org/) in combination with Project Lombok (http://projectlombok.org/)? Lombok provides annotations for removing boilerplate code; however, it doesn't appear to play nicely with Ant4Eclipse (headless compilation of Eclipse projects). For instance, the following Lombok sample compiles fine in Eclipse and javac: import lombok.Getter; public class LombokTest { private @Getter String foo; public LombokTest() { String s = this.getFoo(); } } But compiling with Ant4Eclipse's <buildJdtProject> yields the following: [javac] Compiling 1 source file [javac] ---------- [javac] 1. WARNING in C:\dev\Java\workspace\LombokTest\src\LombokTest.java (at line 4) [javac] private @Getter String foo; [javac] ^^^ [javac] The field LombokTest.foo is never read locally [javac] ---------- [javac] 2. ERROR in C:\dev\Java\workspace\LombokTest\src\LombokTest.java (at line 8) [javac] String s = this.getFoo(); [javac] ^^^^^^ [javac] The method getFoo() is undefined for the type LombokTest [javac] ---------- Has anyone successfully used these libraries together? Thanks! Edit: sample project demonstrating the issue

  • Full Text Search in SQL Server 2008 shows wrong display_item for Thai language

    - by ensecoz
    I am working with SQL Server 2008. My task is to investigate the issue where FTS cannot find the right result for Thai. First, I have the table which enables the FTS on the column 'ItemName' which is nvarchar. The Catalog is created with the Thai Language. Note that the Thai language is one of the languages that doesn't separate the word by spaces, so '????' '???' '????' are written like this in a sentence: '???????????' In the table, there are many rows that include the word (????); for example row#1 (ItemName: '???????????') On the webpage, I try to search for '????' but SQL Server cannot find it. So I try to investigate it by trying the following query in SQL Server: select * from sys.dm_fts_parser(N'"???????????"', 1054, 0, 0) ...to see how the words are broken. The first one is the text to be broken. The second parameter is to specify that we're using Thai (WorkBreaker, so on). Here is the result: row#1 (display_item: '????', source_item: '???????????') row#2 (display_item: '????', source_item: '???????????') row#3 (display_item: '??', source_item: '???????????') Notice that the first and second row display the wrong display_item '?' in the '????' isn't even Thai characters. '?' in '????' is not a Thai character either. So the question is where did those alien characters come from? I guess this why I cannot search for '????' because the word breaker is broken and keeping the wrong character in the indexes. Please help!

  • .NET out of memory troubleshooting

    - by bushman
    After reading a few enlightening articles about memory in the .NET technology, Out of Memory does not refer to physical memory, 597499. I thought I understood why a C# app would throw an out of memory exception -- until I started experimenting with two servers-- both are having 2.5 gigs of ram, windows server 2003 and identical programs running. The only significant difference between the two being one has 7% hard drive storage left and the other more than 50%. The server with 7% storage space left is consistently throwing an out of memory while the other is performing consistently well. My app is a C# web application that process' hundreds of MBs of String object. Why would this difference happen seeing that the most likely reason for the out of memory issue is out of contiguous virtual address space -- What solutions do you guys propose -- and what do you say about the following 1. turn on the 3gb switch to increase the virtual address space -- 2. instead of using one giant string object, break it up into smaller pieces and collect it in a jagged array (here I have to find a way to return to the caller in some other way as right now, the return type is a string) thanks SO

  • Set up Gitosis, but can't clone

    - by Tim Rupe
    I've set up Gitosis on a remote Ubuntu box which I will refer to as linuxserver as my host in the following commands. I'm also connecting from a Windows box using Cygwin. I followed the instructions according to: http://scie.nti.st/2007/11/14/hosting-git-repositories-the-easy-and-secure-way I had no problems up until I needed to clone the gitosis-admin repository to my local machine git clone git@linuxserver:gitosis-admin.git When I do this, the command executes, but hangs there displaying nothing until I ctrl-c to get back to a command prompt. No messages are displayed at all. I'm pretty sure I have my ssh keys set up properly, because logging in using "ssh linuxserver" into my regular account works perfectly without asking for a password. Edit: Over the weekend I set up a near identical Ubuntu box at home, and had no problem setting up Gitosis. The only difference was that I was connecting from OSX instead of Cygwin. Edit: I've also discovered that when using the Bash Shell provided with "Git Extensions", I have no problems, so the issue definitely seems to be some kind of Cygwin conflict. Edit: Just an update, but about a month after posting this question, I switched to Mercurial, and found that I prefer it much more than git. Thanks for the suggestions, but I don't plan on going back to git to try any of them out.

  • Combo box in a scrollable panel causing problems

    - by Dennis
    I have a panel with AutoScroll set to true. In it, I am programmatically adding ComboBox controls. If I add enough controls to exceed the viewable size of the panel a scroll bar appears (so far so good). However, if I open one of the combo boxes near the bottom of the viewable area the combo list isn't properly displayed and the scrollable area seems to be expanded. This results in all of the controls being "pulled" to the new bottom of the panel with some new blank space at the top. If I continue to tap on the drop down at the bottom of the panel the scrollable area will continue to expand indefinitely. I'm anchoring the controls to the left, right and top so I don't think anchoring is involved. Is there something obvious that could be causing this? Update: It looks like the problem lies with anchoring the controls to the right. If I don't anchor to the right then I don't get the strange behavior. However, without right anchoring the control gets cut off by the scroll bar. Here's a simplified test case I built that shows the issue: public Form1() { InitializeComponent(); Panel panel = new Panel(); panel.Size = new Size(80, 200); panel.AutoScroll = true; for (int i = 0; i < 10; ++i) { ComboBox cb = new ComboBox(); cb.Anchor = AnchorStyles.Left | AnchorStyles.Right | AnchorStyles.Top; cb.Items.Add("Option 1"); cb.Items.Add("Option 2"); cb.Items.Add("Option 3"); cb.Items.Add("Option 4"); cb.Location = new Point(0, i * 24); panel.Controls.Add(cb); } Controls.Add(panel); } If you scroll the bottom of the panel and tap on the combo boxes near the bottom you'll notice the strange behavior.

  • iPod touch debugging: Error on install/run only if app exists on device already?

    - by Ben
    Hi all, I am using an iPod to test an app. The device is all set up with the right provisioning profiles, etc-- that's not really the issue. But every time I start the app from Xcode on the device, I get the "A signed resource has been added, modified, or deleted." error from the Organizer window. Wait, I know, you think it's a provisioning profile problem. But here's the kicker: if I just delete the app from the iPod (using the main screen) and try again, it works fine. I only get this error when the app is already installed. The other kicker is that this behavior doesn't happen on an iPhone that I have for occasional testing-- on that device, I can start/restart/restart indefinitely. But using the iPod, my compile-run-test cycle is annoyingly slow since I have to manually delete the app each time. Any ideas? I'm using Xcode 3.2.2 (prerelease) FWIW. The iPod has stock OS 3.1.2 on it. Thanks!

  • deadlock because of foreign key?

    - by George2
    Hello everyone, I am using SQL Server 2008 Enterprise. I met with deadlock in the following store procedure, but because of my fault, I did not record the deadlock graph. But now I can not reproduce deadlock issue. I want to have a postmortem to find the root cause of deadlock to avoid deadlock in the future. The deadlock happens on delete statement. For the delete statement, Param1 is a column of table FooTable, Param1 is a foreign key of another table (refers to another primary key clustered index column of the other table). There is no index on Param1 itself for table FooTable. FooTable has another column which is used as clustered primary key, but not Param1 column. Here is my guess why there is deadlock, and I want to let people review whether my analysis is correct? Since Param1 column has no index, there will be a table scan, and will acquire table level lock, because of foreign key, the delete operation will also need to check master table (e.g. to acquire lock on master table); Some operation on master table acquires master table lock, but want to acquire lock on FooTable; (1) and (2) cause cycle lock which makes deadlock happen. My analysis correct? Any reproduce scenario? create PROCEDURE [dbo].[FooProc] ( @Param1 int ,@Param2 int ,@Param3 int ) AS DELETE FooTable WHERE Param1 = @Param1 INSERT INTO FooTable ( Param1 ,Param2 ,Param3 ) VALUES ( @Param1 ,@Param2 ,@Param3 ) DECLARE @ID bigint SET @ID = ISNULL(@@Identity,-1) IF @ID > 0 BEGIN SELECT IdentityStr FROM FooTable WHERE ID = @ID END thanks in advance, George

  • Page_PreRender fires twice on first load in session

    - by awe
    I have an issue when I access the application, I notice that Page_PreRender is fired twice. This only happens the first time in a new session. It does not happen if I refresh the page, or on postbacks. I use .NET framework 3.5 and the built in ajax functionality. I think the problem is not related to img tag with empty src attribute as I have seen other posts has mentioned, because I see this in both FireFox and IE. The posts I saw about this stated that this was not a problem in IE. I have also searched and found no img tags with empty src in the generated page source, so it should not be this. I have also made a simple test page where I have included some of the functionality, and this does not happen. Here I have also tried to reproduce the empty src bug by including <img src="" /> on the page, but this does not trigger this problem. Have anyone any suggestions on what happens? Note: It is the entire page cycle that is firing twice, not just render.

  • asp.net mvc ajax form helper/post additional data

    - by Jopache
    I would like to use the ajax helper to create ajax requests that send additional, dynamic data with the post (for example, get the last element with class = blogCommentDateTime and send the value of that last one to the controller which will return only blog comments after it). I have successfully done so with the help of jQuery Form plugin like so: $(document).ready(function () { $("#addCommentForm").submit(function () { var lastCommentDate = $(".CommentDateHidden:last").val(); var lastCommentData = { lastCommentDateTicks: lastCommentDate }; var formSubmitParams = { data: lastCommentData, success: AddCommentResponseHandler } $("#addCommentForm").ajaxSubmit(formSubmitParams); return false; }); This form was created with html.beginform() method. I am wondering if there is an easy way to do this using the ajax.beginform() helper? When I try to use the same code but replace html.beginform() with ajax.beginform(), when i try to submit the form, I am issuing 2 posts (which is understandable, one being taken care of by the helper, the other one by me with the JS above. I can't create 2 requests, so this option is out) I tried getting rid of the return false and changing ajaxSubmit() to ajaxForm() so that it would only "prepare" the form, and this leads in only one post, but it does not include the extra parameter that I defined, so this is worthless as well. I then tried keeping the ajaxForm() but calling that whenever the submit button on the form gets clicked rather than when the form gets submitted (I guess this is almost the same thing) and that results in 2 posts also. The biggest reason I am asking this question is that I have run in to some issues with the javascript above and using mvc validation provided by the mvc framework (which i will set up another question for) and would like to know this so I can dive further in to my validation issue.

  • Perceptron Classification and Model Training

    - by jake pinedo
    I'm having an issue with understanding how the Perceptron algorithm works and implementing it. cLabel = 0 #class label: corresponds directly with featureVectors and tweets for m in range(miters): for point in featureVectors: margin = answers[cLabel] * self.dot_product(point, w) if margin <= 0: modifier = float(lrate) * float(answers[cLabel]) modifiedPoint = point for x in modifiedPoint: if x != 0: x *= modifier newWeight = [modifiedPoint[i] + w[i] for i in range(len(w))] w = newWeight self._learnedWeight = w This is what I've implemented so far, where I have a list of class labels in answers and a learning rate (lrate) and a list of feature vectors. I run it for the numbers of iterations in miter and then get the final weight at the end. However, I'm not sure what to do with this weight. I've trained the perceptron and now I have to classify a set of tweets, but I don't know how to do that. EDIT: Specifically, what I do in my classify method is I go through and create a feature vector for the data I'm given, which isn't a problem at all, and then I take the self._learnedWeight that I get from the earlier training code and compute the dot-product of the vector and the weight. My weight and feature vectors include a bias in the 0th term of the list so I'm including that. I then check to see if the dotproduct is less than or equal to 0: if so, then I classify it as -1. Otherwise, it's 1. However, this doesn't seem to be working correctly.

  • How to make a mapped field inherited from a superclass transient in JPA?

    - by Russ Hayward
    I have a legacy schema that cannot be changed. I am using a base class for the common features and it contains an embedded object. There is a field that is normally mapped in the embedded object that needs to be in the persistence id for only one (of many) subclasses. I have made a new id class that includes it but then I get the error that the field is mapped twice. Here is some example code that is much simplified to maintain the sanity of the reader: @MappedSuperclass class BaseClass { @Embedded private Data data; } @Entity class SubClass extends BaseClass { @EmbeddedId private SubClassId id; } @Embeddable class Data { private int location; private String name; } @Embeddable class SubClassId { private int thingy; private int location; } I have tried @AttributeOverride but I can only get it to rename the field. I have tried to set it to updatable = false, insertable = false but this did not seem to work when used in the @AttributeOverride annotation. See answer below for the solution to this issue. I realise I could change the base class but I really do not want to split up the embedded object to separate the shared field as it would make the surrounding code more complex and require some ugly wrapping code. I could also redesign the whole system for this corner case but I would really rather not. I am using Hibernate as my JPA provider.

  • How do you implement a good profanity filter?

    - by Ben Throop
    Many of us need to deal with user input, search queries, and situations where the input text can potentially contain profanity or undesirable language. Oftentimes this needs to be filtered out. Where can one find a good list of swear words in various languages and dialects? Are there APIs available to sources that contain good lists? Or maybe an API that simply says "yes this is clean" or "no this is dirty" with some parameters? What are some good methods for catching folks trying to trick the system, like a$$, azz, or a55? Bonus points if you offer solutions for PHP. :) Edit: Response to answers that say simply avoid the programmatic issue: I think there is a place for this kind of filter when, for instance, a user can use public image search to find pictures that get added to a sensitive community pool. If they can search for "penis", then they will likely get many pictures of, yep. If we don't want pictures of that, then preventing the word as a search term is a good gatekeeper, though admittedly not a foolproof method. Getting the list of words in the first place is the real question. So I'm really referring to a way to figure out of a single token is dirty or not and then simply disallow it. I'd not bother preventing a sentiment like the totally hilarious "long necked giraffe" reference. Nothing you can do there. :)
