• Application leaking Strings?

  - by Jörg B.

  My .net application does some heavy string loading/manipulation and unfortunately the memory consumption keeps rising and rising and when looking at it with a profiler I see alot of unreleased string instances. Now at one point of time or another I do need all objects t hat do have these string fields, but once done, I could get rid of e.g. the half of it and I Dispose() and set the instances to null, but the Garbage Collector does not to pick that up.. they remain in memory (even after half an hour after disposing etc). Now how do I get properly rid of unneeded strings/object instances in order to release them? They are nowhere referenced anymore (afaik) but e.g. aspose's memory profiler says their distance to the gc's root is '3'?

• Multiple Questions per page using Drupal Quiz

  - by Andrew

  I'm using the Drupal Quiz module, and have setup some basic quizzes and stuff like that. However some further customization is required, involving more than 1 question per page, and a multi-type answer in this type of format: Question 1: Describe 4 things you did last summer a) [ short answer space - text field ] b) "I wept" c) "My whole family died so I learned self reliance" d) "I got another xbox" Question 2: Describe 2 things you hate about yourself a) "My arms are way shorter than my legs" b) "I was born without human emotion" So I guess in two parts, how to show multiple questions per page, and then how to allow multiple text fields for answers. Oh and this quiz is not graded, it's like a self assessment. Thanks!

• Sanitize json input to a java server

  - by morgancodes

  I'm using json to pass data between the browser and a java server. I'm using Json-lib to convert between java objects and json. I'd like to strip out susupicious looking stuff (i.e "doSomethingNasty().) from the user input while converting from json to java. I can imagine several points at which I could do this: I could examine the raw json string and strip out funny-looking stuff I could look for a way to intercept every json value on its way into the java object, and look for funny stuff there. I could traverse my new java objects immediately after reconstitution from json, look for any fields that are Strings, and stripp stuff out there. What's the best approach? Are there any technologies built for this this task that I tack tack on to what I have already?

• Custom login in Django

  - by alpgs

  Django newbie here. I wrote simplified login form which takes email and password. It works great if both email and password are supplied, but if either is missing i get KeyError exception. According to django documentation this should never happen: By default, each Field class assumes the value is required, so if you pass an empty value -- either None or the empty string ("") -- then clean() will raise a ValidationError exception I tried to write my own validators for fields (clean_email and clean_password), but it doesn't work (ie I get KeyError exception). What am I doing wrong? class LoginForm(forms.Form): email = forms.EmailField(label=_(u'Your email')) password = forms.CharField(widget=forms.PasswordInput, label=_(u'Password')) def clean_email(self): data = self.cleaned_data['email'] if not data: raise forms.ValidationError(_("Please enter email")) return data def clean_password(self): data = self.cleaned_data['password'] if not data: raise forms.ValidationError(_("Please enter your password")) return data def clean(self): try: username = User.objects.get(email__iexact=self.cleaned_data['email']).username except User.DoesNotExist: raise forms.ValidationError(_("No such email registered")) password = self.cleaned_data['password'] self.user = auth.authenticate(username=username, password=password) if self.user is None or not self.user.is_active: raise forms.ValidationError(_("Email or password is incorrect")) return self.cleaned_data

• Databinding multiple tables linq query to gridview?

  - by Curtis White

  My question is how can I display a linq query in a gridview that has data from multiple tables AND allow the user to edit some of the fields or delete the data from a single table? I'd like to do this with either a linqdatasource or a linq query. I'm aware I can set the e.Result to the query on the selecting event. I've also been able to build a custom databound control for displaying the linq relations (parent.child). However, I'm not sure how I can make this work with delete? I'm thinking I may need to handle the delete event with custom code.

• Class Methods Inheritence

  - by Roman A. Taycher

  I was told that static methods in java didn't have Inheritance but when I try the following test package test1; public class Main { /** * @param args the command line arguments */ public static void main(String[] args) { TB.ttt(); TB.ttt2(); } } package test1; public class TA { static public Boolean ttt() { System.out.println("TestInheritenceA"); return true; } static public String test ="ClassA"; } package test1; public class TB extends TA{ static public void ttt2(){ System.out.println(test); } } it printed : TestInheritenceA ClassA so do java static methods (and fields have) inheritance (if you try to call a class method does it go down the inheritance chai looking for class methods). Was this ever not the case,are there any inheritance OO languages that are messed up like that for class methods?

• How do I keep the width of a table constant when it has dynamic content?

  - by Lincoln Bergeson

  How do I keep the width of a table constant, even when the content of that table is interactively changing? Old Post: How do I insert a variable length tab in HTML? I want certain dynamic fields in my table to line up but they're changing width constantly. EDIT: What I mean is this: in any text editor I can press tab to align certain bits of text, and not care about how many spaces there are. In fact, the number of spaces there needs to be for the leftmost part of the text can change, and I still won't care, as long as the text lines up. How do I do this is in HTML?

• A* pathfinder obstacle collision problem

  - by Cheesebaron

  I am working on a project with a robot that has to find its way to an object and avoid some obstacles when going to that object it has to pick up. The problem lies in that the robot and the object the robot needs to pick up are both one pixel wide in the pathfinder. In reality they are a lot bigger. Often the A* pathfinder chooses to place the route along the edges of the obstacles, sometimes making it collide with them, which we do not wish to have to do. I have tried to add some more non-walkable fields to the obstacles, but it does not always work out very well. It still collides with the obstacles, also adding too many points where it is not allowed to walk, results in that there is no path it can run on. Do you have any suggestions on what to do about this problem?

• ASP.NET Dates Deployment Issue

  - by Jonathan Stowell

  Hi guys, I recently bought some webspace with dailyrazor.com. I have deployed an application I have been working on to the server and am currently trying to workout the bugs but I can't seem to solve this one. I have set up my database in Visual Studio to use the one I have create with dailyrazor the same db the deployed version will use. I am using British Dates and on my localhost datetime is displayed: 27/05/2010 09:00 However on the dailyrazor host it is displayed: 5/27/2010 9:00 AM Short Dates e.g. 27/04/2010 display the same on both servers. This is causing some issues when entering data as errors occur on date fields. Any help would be appreciated. Thanks, Jon

• disable text drag and drop

  - by maniek

  There is a common feature of modern browsers where a user can select some text and drag it to an input field. Within the same field it causes moving of text, between different fields it does copying. How do I disable that? If there is no portable way, I am mostly interested in firefox. This is an intranet webapp, so I am also interested in modifying the browser/getting a plugin to do this. Maybe some system-level settings (I`m on windows XP)? I need to keep the default select-copy-paste functionality. The background is I have multiple-field data entry forms, and users often drag something by mistake.

• Codeigniter - form not rendering on live server?

  - by pingu

  hi guys, I've written a small website with CI, which is all working fine on dev. However, when I copy the files over for live, everything works except for my form which is not being rendered. I am using <?php echo form_open('home'); ?> and <?php echo form_close(); ?> The form fields within the form, which I'm generating as follows are being rendered fine, but there is simply no form around them?! <?php $data = array( 'name'=> 'name', 'id'=> 'name', 'class'=>'textfield', 'value' => set_value('name') ); echo form_input($data); ?> Any ideas - I've used CI on a few apps, and this is the first time I've come across this issue. I've got all the helpers etc called correctly, as this is working perfectly in the development environment.

• displaying current minute of a soccer match

  - by zurna

  I could not figure out the logic I would need to display a current minute of a soccer match. I have three fields in the database. DateFirstStarted DateSecondStarted DateFullEnded I should enter DateFirstStarted when the game starts and on the website. i.e. game starts at 7:05pm, on 7:25pm it should display '20 on the website. However, it should stop on the 45th minute. Then, I enter DateSecondStarted when the second half starts and should count from 46 to 90 and freeze there. Do I make sense? How can I do it? Is there a better way to do this?

These are called from a string array in strings.xml <string name="app_name">Taxi Me</string> <string-array name="taxi_array"> <item>Barrys Taxi</item> <item>Boom Taxi</item> </string-array> What i was trying to do is create subitems for these so that i can show fields such as address and contact details etc. I made a customlistview a while back but cant work out how i can do it using the strings.xml file? Are there any particular tags i need to use so they show up in the list view? Any help would be greatly appreciated. Thanks

• Can I prevent RequiredFieldValidation from triggering against postbacks from a specific control.

  - by marcusstarnes

  I have a web form with a number of textbox controls which I've associated RequiredFieldValidator's with. I have a ValidationSummary control on the page to render any incomplete fields when I submit the page. However, I've just had to add an image upload facility to the same page, and have an 'Upload' button which I have posting back to perform the upload. I don't want this upload button to trigger the RequiredFieldValidators for the rest of the page though - I want this upload postback to be ignored as far as the validation goes. What's the best way to stop the RequiredFieldValidator's from firing when I submit this upload button on the page because at the moment, the upload won't occur unless I have first field out all of the other textbox controls on the page.

• Do you use enums in your data applications and how?

  - by Ivan

  My practice shows that a general enterprise application has a lot of entities which's nature corresponds to an elementary enumeration. For example We may have an Order entity which may have such fields as "OrderType", "OrderStatus", "Currency", etc. referencing corresponding Entities which are nothing more than just a textual name bound to a key to be referenced. Using enums would look very natural here. But entities have to be defined in application code at design-time, am I right? While in we need to be able to CRUD enum value variants at runtime and use enums in server-side SQL queries (like stored procedures and views). What are you practices and thoughts on this subject? I am particularly interested in C#4, linq and T-SQL.

• Question About DateCreated and DateModified Columns - SQL Server

  - by user311509

  CREATE TABLE Customer ( customerID int identity (500,20) CONSTRAINT . . dateCreated datetime DEFAULT GetDate() NOT NULL, dateModified datetime DEFAULT GetDate() NOT NULL ); When i insert a record, dateCreated and dateModified gets set to default date/time. When i update/modify the record, dateModified and dateCreated remains as is? What should i do? Obviously, i need to dateCreated value to remain as was inserted the first time and dateModified keeps changing when a change/modification occurs in the record fields. In other words, can you please write a sample quick trigger? I don't know much yet...

• Is this code thread-safe?

  - by mafutrct

  I've got a class with several properties. On every value update, a Store method is called with stores all fields (in a file). private int _Prop1; public int Prop1 { get { return _Prop1; } set { _Prop1 = value; Store(); } } // more similar properties here... private XmlSerializer _Ser = new ...; private void Store() { lock (_Ser) { using (FileStream fs = new ...) { _Ser.Serialize (fs, this); } } } Is this design thread-safe? (Btw, if you can think of a more appropriate caption, feel free to edit.)

• Xcode 4: deleting items in Build Settings

  - by occulus

  In XCode 4.0 there's a newly designed Build Settings page. My problem is that I can't see how to remove a setting once I've specified it. Example: I've changed "Versioning System" to "Apple Generic" at the target level. Afterwards I realised I should set it at the project level, and so I want to delete the target level setting. However, there's no way I can see to remove the setting -- you click on it and there's two options, neither of which is the default "not specified" empty setting. Hitting the delete key on the keyboard nothing. The same goes for fields that accept text -- if I try to delete a setting by just deleting all the text set, it still shows that field in green, but with no text in it, and regards it as the presence of a setting.

• Hibernate: same generated value in two properties

  - by Markos Fragkakis

  Hi, I have an entity A with fields: aId (the system id) bId I want the first to be generated: @Id @Column(name = "PRODUCT_ID", unique = true, nullable = false, precision = 12, scale = 0) @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "PROD_GEN") @BusinessKey public Long getAId() { return this.aId; } I want the bId to be initially exactly as the aId. One approach is to insert the entity, then get the aId generated by the DB (2nd query) and then update the entity, setting the bId to be equal to aId (3rd query). Is there a way to get the bId to get the same generated value as aId? Note that afterwards, I want to be able to update bId from my gui. If the solution is JPA, even better.

• Stored Procedure with ALTER TABLE

  - by psayre23

  I have a need to sync auto_increment fields between two tables in different databases on the same MySQL server. The hope was to create a stored procedure where the permissions of the admin would let the web user run ALTER TABLE [db1].[table] AUTO_INCREMENT = [num]; without giving it permissions (That just smells of SQL injection). My problem is I'm receiving errors when creating the store procedure. Is this something that is not allowed by MySQL? DROP PROCEDURE IF EXISTS sync_auto_increment; CREATE PROCEDURE set_auto_increment (tableName VARCHAR(64), inc INT) BEGIN ALTER TABLE tableName AUTO_INCREMENT = inc; END;

• PL/SQL Package invalidated

  - by FrustratedWithFormsDesigner

  I have a script that makes use of a package (PKG_MY_PACKAGE). I will change some of the fields in a query in that package and then recompile it (I don't change or compile any other packages). I run the script and I get an error that looks like ORA-04068: existing state of packages has been discarded ORA-04061: existing state of package body "USER3.PKG_MY_PACKAGE" has been invalidated ORA-04065: not executed, altered or dropped package body "USER3.PKG_MY_PACKAGE" ORA-06508: PL/SQL: could not find program unit being called: "USER3.PKG_MY_PACKAGE" ORA-06512: at line 34 I run the script again (without changing anything else in the system) and the script executes successfully. I thought that when I compiled before I executed the script that would fix any invalid references. This is 100% reproducible, and the more I test this script the more annoying it gets. What could cause this, and what would fix it? (oracle 10g, using PL/SQL Developer 7)

• Lucene.NET - Find documents that do not contain a specified field

  - by Brandon

  Let's say I have 2 instance of a class called 'Animal'. Animal has 3 fields: Name, Age, and Type The name field is nullable, so before I insert an instance of Animal as a Lucene indexed document, I check if Animal.Name == null, and if it does, I do not insert it as a field in my document. If I were to retrieve all animals, I would see that the Name field does not exist and I can set its value to null. However, there may be situations where I want to say "Get me all animals that do not have a name specified yet." In this situation I want to retrieve all Lucene.NET documents from my animal index that do not contain the Name field. Is there an easy way to do this with Lucene.NET? I want to stay away from having to perform some sort of hack to check if my name field has a value of 'null'.

• Passing single attributes to associated factories

  - by lambdabutz

  I'm looking for a way to pass fields into the factories of associated models without having to explicitly call the factory itself. For example, lets say I have some factories like so: Factory.define :person do |person| person.name "Default Bob" person.sex "M" person.house {|p| p.association(:house)} end Factory.define :house do |house| house.color "Red" house.has_ac true house.suburb {|h| h.association(:suburb)} end Factory.define :suburb do |suburb| suburb.name "Little boxes" end This is fine and all, but if I want to use factories to create someone in a specific house in a specific suburb I have do this: sub = Factory(:suburb, :name => "Blue town") house = Factory(:house, :color => "Blue", :suburb => sub) person = Factory(:person, :name => "Bill", :house => house) While this isn't bad in this small case, my actual models sometimes have 7 or 8 associations, and when I want to create an object whose associations I only care about a single attribute, the code for this starts to get really heavy. Is there somewhat I can pass attributes to nested Factories without having to recall the Factory itself?
