  - by newName

  I would like to open a popup window using javascript in my c#.net app. This is the code in the body tag in my webform <script language=javascript> function openWindow(strEmail) { window.open('CheckEmail.aspx?email=' + strEmail + , 'Check Email','left=100,top=100,toolbar=no,scrollbars=yes,width=680,height=350'); return false; } </script> this is my code in the Page_Load section this.btnCheck.Attributes.Add("onclick", "return openWindow(" + txtEmail.Text + ");"); right now I'm trying to pass the string from my textbox "txtEmail" so in my popup window i can get the request.querystring but Im a little unsure of how the syntax is.

• Can't access dojo object property using string variable

  - by Kareem

  I am retrieving a json associative array using a dojo xhrGet request. The data comes back just fine, however I need the app to be able to display the keys and their properties (or values) without knowing the keys beforehand. So, I do the following: function getData() { dojo.xhrGet( { url: "ytd_process.php", handleAs: "json", load: function(response) { for (var key in response) { dojo.byId("boxes").innerHTML+="<div id=\"box\">"+key+":"+response.key+"</div>"; } console.dir(response); // Dump it to the console } }); }; The keys are retrieved and displayed on the page, but the response.key returns undefined. I know the syntax is correct because if I replace .key with an actual key value it will display correctly. It appears it doesn't like a string as the key. Any help or advice would be greatly appreciated. Thank you.

• A simple factory_girl question

  - by gmile

  I have two factories (post_factory.rb, comment_factory.rb) in separate files. I'd like to create a bit complex factory, which will create a post with associated comments for me. I created a third file, called complex_factory.rb, and wrote the following code: Factory.define :post_with_comments, :parent => :post do |post| post.after_create { |p| Factory(:user_last_state, :post => p) } end But rake spec raises an error, stating that the file is unaware of post and comment factories. At the very next moment, I naïvely wrote requires at the top: require "post_factory.rb" require "comment_factory.rb" But that didn't gave any proper result. Maybe this requires actually looking the wrong direction? Or they pretty much don't matter (as registering factories for visibility might be more complex that I assume). Am I missing something? Any ideas?

• C# Design Layout/Patterns

  - by wpfwannabe

  I am still fairly new to C# and I am trying to decide the best way to structure a new program. Here is what I want to do and I would like feed back on my idea. Presentation Layer Business Layer (Separate Class Library) Data Layer (Separate Class Library) Model Layer (Separate Class Library) What I am struggling with is if it is ok to have the classes in the Data Layer and Business Layer inherit from the types I define in Model Layer. This way I can extended the types as needed in my Business Layer with any new properties I see fit. I might not use every property from the Model type in my Business Layer class but is that really a big deal? If this isn't clear enough I can try and put together an example.

• updating all other records

  - by Andrew Welch

  Hi, I've got a query below. I want to add a condition that if the parameter of @IsPrestigeFeatured = 0 then update all of the other rows < PropertyId in the IsprestigeFeatured column to 0 and if @IsPrestigeFeatured = 1 then IsprestigeFeatured = 1 where propertyId = PropertyId. I've looked into case statements / if statements but I can't seem to get the syntax right. cheers ALTER PROCEDURE dbo.Update_Property @propertyId int, @propertyTypeId int, @Name ntext, @Price int, @DescriptionResultsExcerpt text, @Description ntext, @Characteristics ntext, @IsRenovation int, @IsCharacter int, @IsPrestige int, @IsHomepageFeatured int, @IsPrestigeFeatured int, @CityId int, @DepartmentId int, @CommuneId int As UPDATE Property SET Name = @Name, PropertyTypeID = @propertyTypeId, Price = @Price, DescriptionResultsExcerpt = @DescriptionResultsExcerpt, Description = @Description, Characteristics = @Characteristics, IsRenovation = @IsRenovation, IsCharacter = @IsCharacter, IsPrestige = @IsPrestige, IsHomepageFeatured = @IsHomepageFeatured, IsPrestigeFeatured = @IsPrestigeFeatured, CityId = @CityId, DepartmentId = @DepartmentId, CommuneId = @CommuneId FROM Property WHERE (PropertyId = @PropertyId)

• Java == operator. "Invalid assignment operator"

  - by Tom

  Hi, I was trying to write a simple method boolean validate(MyObject o) { return o.getPropertyA() == null && o.getPropertyB()==null; } And got a strange error on the == null part. Maybe my Java is rusty after a season in PLSQL. Consider this: Integer i = 4; i ==null; //compile error: Syntax error on token ==. Invalid assignment operator. Integer i2 = 4; if (i==null); //No problem How can this be ? Any explanation ? Im using jdk160_05.

• Inside a decorator-class, access instance of the class which contains the decorated method

  - by ifischer

  I have the following decorator, which saves a configuration file after a method decorated with @saveconfig is called: class saveconfig(object): def __init__(self, f): self.f = f def __call__(self, *args): self.f(object, *args) # Here i want to access "cfg" defined in pbtools print "Saving configuration" I'm using this decorator inside the following class. After the method createkvm is called, the configuration object self.cfg should be saved inside the decorator: class pbtools() def __init__(self): self.configfile = open("pbt.properties", 'r+') # This variable should be available inside my decorator self.cfg = ConfigObj(infile = self.configfile) @saveconfig def createkvm(self): print "creating kvm" My problem is that i need to access the object variable self.cfg inside the decorator saveconfig. A first naive approach was to add a parameter to the decorator which holds the object, like @saveconfig(self), but this doesn't work. How can I access object variables of the method host inside the decorator? Do i have to define the decorator inside the same class to get access?

• Author in wiki, generate PDF documents, CHM files or embedded help

  - by Dilum Ranatunga

  Anyone know of a wiki or wiki plugin that generates a PDF file or CHM file that spans the entire wiki? I would like to have control of the table of contents. I would like the internal and external links to work. Ideally allow for tweaking the output template, but that is not a deal-breaker. I want to generate content using WIKI syntax and mindset (lots of cross-links etc), but ship the content in PDF, CHM or an embedded application form. Something friendlier than installing the wiki software on the enduser machine...

• in-memory database in Python

  - by Claudiu

  I'm doing some queries in Python on a large database to get some stats out of the database. I want these stats to be in-memory so other programs can use them without going to a database. I was thinking of how to structure them, and after trying to set up some complicated nested dictionaries, I realized that a good representation would be an SQL table. I don't want to store the data back into the persistent database, though. Are there any in-memory implementations of an SQL database that supports querying the data with SQL syntax?

• C# Language Design: explicit interface implementation of an event

  - by ControlFlow

  Small question about C# language design :)) If I had an interface like this: interface IFoo { int Value { get; set; } } It's possible to explicitly implement such interface using C# 3.0 auto-implemented properties: sealed class Foo : IFoo { int IFoo.Value { get; set; } } But if I had an event in the interface: interface IFoo { event EventHandler Event; } And trying to explicitly implement it using field-like event: sealed class Foo : IFoo { event EventHandler IFoo.Event; } I will get the following compiler error: error CS0071: An explicit interface implementation of an event must use event accessor syntax I think that field-like events is the some kind of dualism for auto-implemented properties. So my question is: what is the design reason for such restriction done?

• Insert xelements using LINQ Select?

  - by Simon Woods

  I have a source piece of xml into which I want to insert multiple elements which are created dependant upon certain values found in the original xml At present I have a sub which does this for me: <Extension()> Public Sub AddElements(ByVal xml As XElement, ByVal elementList As IEnumerable(Of XElement)) For Each e In elementList xml.Add(e) Next End Sub And this is getting invoked in a routine as follows: Dim myElement = New XElement("NewElements") myElement.AddElements( xml.Descendants("TheElements"). Where(Function(e) e.Attribute("FilterElement") IsNot Nothing). Select(Function(e) New XElement("NewElement", New XAttribute("Text", e.Attribute("FilterElement").Value)))) Is it possible to re-write this using Linq syntax so I don't need to call out to the Sub AddElements but could do it all in-line Many Thx Simon

• c# Attribute Question

  - by Petoj

  Well i need some help here i don't know how to solve this problem. the function of the attribute is to determine if the function can be run... So what i need is the following: The consumer of the attribute should be able to determine if it can be executed. The owner of the attribute should be able to tell the consumer that now it can/can't be executed (like a event). It must have a simple syntax. This is what i have so far but it only implements point 1, 3. [AttributeUsage(AttributeTargets.Method, AllowMultiple = false)] public class ExecuteMethodAttribute : Attribute { private Func<object, bool> canExecute; public Func<object, bool> CanExecute { get { return canExecute; } } public ExecuteMethodAttribute() { } public ExecuteMethodAttribute(Func<object, bool> canExecute) { this.canExecute = canExecute; } }

• How to perform a literal match with regex using wildcard

  - by kashif4u

  I am trying to perform literal match with regular expression using wildcard. string utterance = "Show me customer id 19"; string pattern 1 = "*tom*"; string patter 2 = "*customer id [0-9]*"; Desired results: if (Regex.IsMatch(utterance, pattern 1 )) { MATCH NOT FOUND } if (Regex.IsMatch(utterance, pattern 2 )) { MATCH FOUND } I have tried looking for literal match solution/syntax in wildcard but having difficulty. Could you also enlighten me with with an example on possible Pattern Matching Strength algorithm i.e. if code match 90 select? Note: I have table with 100000 records to perform literal matches from user utterances. Thanks in advance.

• Am I immoral for using a variable name that differs from its type only by case?

  - by Jason Baker

  For instance, take this piece of code: var person = new Person(); or for you Pythonistas: person = Person() I'm told constantly how bad this is, but have yet to see an example of the immorality of these two lines of code. To me, person is a Person and trying to give it another name is a waste of time. I suppose in the days before syntax highlighting, this would have been a big deal. But these days, it's pretty easy to tell a type name apart from a variable name. Heck, it's even easy to see the difference here on SO. Or is there something I'm missing? If so, it would be helpful if you could provide an example of code that causes problems.

• Retrieving accessors in IronRuby

  - by rsteckly

  I'm trying to figure out how to retrieve the value stored in the Person class. The problem is just that after I define an instance of the Person class, I don't know how to retrieve it within the IronRuby code because the instance name is in the .NET part. /*class Person attr_accessor :name def initialize(strname) self.name=strname end end*/ //We start the DLR, in this case starting the Ruby version ScriptEngine engine = IronRuby.Ruby.CreateEngine(); ScriptScope scope = engine.ExecuteFile("c:\\Users\\ron\\RubymineProjects\\untitled\\person.rb"); //We get the class type object person = engine.Runtime.Globals.GetVariable("Person"); //We create an instance object marcy = engine.Operations.CreateInstance(person, "marcy");

• what is order notation f(n)=O(g(n))?

  - by Lopa

  2 questions: question 1: under what circumstances would this[O(f(n))=O(k.f(n))] be the most appropriate form of time-complexity analysis? question 2: working from mathematical definition of O notation, show that O(f(n))=O(k.f(n)), for positive constant k.? My view: For the first one I think it is average case and worst case form of time-complexity. am i right? and what else do i write in that? for the second one I think we need to define the function mathematically, so is the answer something like because the multiplication by a constant just corresponds to a readjustment of value of the arbitrary constant 'k' in definition of O.

• SharePoint Custom Application Page does not recognize tagPrefix defined in custom web.config

  - by Hasan Khan

  I have a custom application page integrated in Centeral Administration. My application pages are placed in a subfolder in Template\Admin folder. I placed my own web.config in my subfolder and added tagPrefixes in the control section. However when I open my application page ASP.NET throws the exception that the tag SharePoint:InputFormTextBox was not recognized. Moving the add tagprefix statements in root web.config solves the problem but thats not acceptable in my case and I can't define them in individual pages either. What am I doing wrong? Or it doesn't work this way? What can i do to achieve this?

• 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

• iphone sdk conditional in switch function

  - by Oliver

  I'm trying to make a random image appear on the press of a button. So it generates a random number, and the switch algorithm swaps the chosen image with the one in the imgview. but I want a switch in the settings app to toggle which set of images to use. I know pretty much how to do it...it's just that it doesn't work. I'm missing some syntax thing...Please help, stackoverflow? it's my birthday. int Number = rand() %30; NSString *toggleValue = [[NSUserDefaults standardUserDefaults] stringForKey:@"enabled_preference"]; switch (Number) { if (*toggleValue == 0) { case 0: picture.image = [UIImage imageNamed:@"1.png"]; break; case 1: picture.image = [UIImage imageNamed:@"2.png"]; break;} else { case 0: picture.image = [UIImage imageNamed:@"3.png"]; break; case 1: picture.image = [UIImage imageNamed:@"4.png"]; break;} }

• Drop a DB2 view if it exists...

  - by grenade

  Why doesn't this work in IBM Data Studio (Eclipse): IF EXISTS (SELECT 1 FROM SYSIBM.SYSVIEWS WHERE NAME = 'MYVIEW' AND CREATOR = 'MYSCHEMA') THEN DROP VIEW MYSCHEMA.MYVIEW; END IF; I have a feeling it has to do with statement terminators (;) but I can't find a syntax that works. Another similar question at http://stackoverflow.com/questions/355687/how-to-check-a-procedure-view-table-exists-or-not-before-dropping-it-in-db2-9-1 suggests that they had to create a proc but this isn't a solution for us.

• Get clientid in user control from external javascript file

  - by Giorgi

  Hello, I am developing a user control (ascx) in ASP.NET which uses javascript for manipulating controls. Currently the javascript code is inlined and uses <%= somecontrol.ClientID %> to get the control it needs. I want to put the javascript file in external file but from external file I cannot use the above syntax for retrieving controls. I have read about possible solutions in this and this answers but the problem is that the user control can be placed multiple times on page. This means that the Controls array (mentioned in the answers) will be rendered several times with different items. As a result the script will not be able to retrieve the id it needs. If I put <%= ClientId %> in the name of array that holds items then I will have the same problem as I am trying to solve. Any ideas?

• resolving localhost in php so can be views outside VM

  - by DA

  I'm running Windows 7. Within, I'm running Virtualbox and Ubuntu. Within Ubuntu, I'm running Apache and using PHP codeigniter. To reference our CSS and JS files, we use this syntax: <?php echo site_url('css/styles.css'); ?> When viewing the site locally (within Ubuntu VM) that resolves to: http://localhost/styles.css So works fine. The catch is when I access that site from within Windows 7 (for IE testing). To access the site in Windows 7, I refer to the IP address of the VM: http://xx.x.x.x/ That loads the site but, alas, all the site_url variables are still being rewritten as 'localhost'. Said files obviously don't exist on the localhost of my windows 7. Is there a way around this short of just hard-coding relative links in my PHP file?

• emacs indentation in asm mode

  - by Gauthier

  I am looking for the equivalent of c-indent-level and ruby-indent-level, for asm-mode. That is, I want to force the indentation to 4 spaces, and I want them to be replaced with blanks. What I've seen tells me it does not exist for asm-mode. Could someone please tell me this is wrong? I tried this also: http://stackoverflow.com/questions/69934/set-4-space-indent-in-emacs-in-text-mode , to no av. I have tried: (setq tab-width 4) (setq indent-line-function 'insert-tab) (setq asm-indent-level 4) This works however: (custom-set-variables '(tab-stop-list (quote (4 8 12 16 20 24 28 32 36 40 44 48 52 56 60 64 68 72 76 80 84 88 92 96 100 104 108 112 116 120)))) But I wonder if there is a way to define that for asm-mode only. What if I wanted to keep the default tab behaviour for other modes?
