• ASP.NET Hosting Options

  - by Adam Haile

  I'm not trying to start a "which language is better" argument here, so please don't go there. I typically use PHP for most of my web development (mostly because hosting is cheap), but for various reasons I'm looking to use ASP.NET for a couple new projects. But one of the major reasons I've stayed away from ASP.NET up until now is the cost. I've seen some budget hosting options, but they always seem a little sketchy to me. From what I've generally found, that's just the way the hosting scene looks for ASP.NET unless you want to go dedicated. Does anyone have any good suggestions for a solid ASP.NET host with a good feature set and reliability for my money? Also, are there any options out there along the lines of Amazon's Elastic Compute Cloud? And yes, I know... Mono. I'm talking about Windows based "grid" hosting options?

• ASP User Control Issue

  - by Steven

  I am attempting to construct my own date picker using code from several sources. Why won't the calendar hide when visible? myDate.ascx <%@ Control Language="vb" AutoEventWireup="false" CodeBehind="myDate.ascx.vb" Inherits="Website.myDate" %> <asp:TextBox ID="dateText" runat="server" > </asp:TextBox> <asp:Button ID="dateBtn" runat="server" UseSubmitBehavior="false" Text="x" /> <asp:Calendar ID="dateCal" runat="server" ></asp:Calendar> myDate.ascx.vb Partial Public Class myDate Inherits System.Web.UI.UserControl Protected Sub dateCal_SelectionChanged(ByVal sender As Object, ByVal e As EventArgs) Handles dateCal.SelectionChanged dateText.Text = dateCal.SelectedDate ' Update text box' dateCal.Visible = False ' Hide calendar' End Sub Protected Sub dateCal_VisibleMonthChanged(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.MonthChangedEventArgs) Handles dateCal.VisibleMonthChanged dateCal.Visible = True ' For some reason, changing the month hides the calendar (so show it)' End Sub Private Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load dateCal.Visible = False ' Hide calendar on load' End Sub Protected Sub dateBtn_Click(ByVal sender As Object, ByVal e As EventArgs) Handles dateBtn.Click dateCal.Visible = Not dateCal.Visible ' On button press, toggle visibility' End Sub End Class

• Scala: Can I nudge a combinator parser to be locally greedy?

  - by eed3si9n

  Suppose I have an ambiguous language expressed in combinator parser. Is there a way to make certain expressions locally greedy? Here's an example of what I mean. import scala.util.parsing.combinator._ object Example extends JavaTokenParsers { def obj: Parser[Any] = (shortchain | longchain) ~ anyrep def longchain: Parser[Any] = zero~zero~one~one def shortchain: Parser[Any] = zero~zero def anyrep: Parser[Any] = rep(any) def any: Parser[Any] = zero | one def zero: Parser[Any] = "0" def one: Parser[Any] = "1" def main(args: Array[String]) { println(parseAll(obj, args(0) )) } } After compiling, I can run it as follows: $ scala Example 001111 [1.7] parsed: ((0~0)~List(1, 1, 1, 1)) I would like to somehow instruct the first part of obj to be locally greedy and match with longchain. If I switch the order around, it matches the longchain, but that's not because of the greediness. def obj: Parser[Any] = (longchain | shortchain) ~ anyrep

• Too many argumants for function

  - by Stas Kurilin

  I'm starting learning Lisp with Java background. In SICP's exercise there is many tasks where students should create abstract functions with many parameters, like (define (filtered-accumulate combiner null-value term a next b filter)...) in exercise 3.11. In Java (language with safe, static typing discipline) - method with more than 4 arguments usually smells, but in Lisp/Scheme it doesnt, does it? I'm wandering how many arguments do you use in you functions? If you use it in production, do you make such many layers?

• Custom Types in WCF Rest

  - by user316341

  I am using the Rest Singleton WCF Service temple from the Rest Starter Kit. The temples uses sample item as its sample Item. i am attempting to replace that sample ITem with a custom type from web reference in my ASP.Net project .dll. The types and name spaces are found and i can replace the sample item in the code. when i run the application i get this error: "Exception has been thrown by the target of an invocation." when this line is executed "return new SingletonServiceHost(serviceType, baseAddresses);" <%@ ServiceHost Language="C#" Debug="true" Service="SAUDServices.Service" Factory="SAUDServices.AppServiceHostFactory"%> using System; using System.ServiceModel; using System.ServiceModel.Activation; using Microsoft.ServiceModel.Web.SpecializedServices; using Stretchatyourdesk; namespace SAUDServices { class AppServiceHostFactory : ServiceHostFactory { protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses) { return new SingletonServiceHost(serviceType, baseAddresses); } } }

• Creating a child process on Unix systems?

  - by Hakan Svensson

  I'm trying to create a child process in another process. I am writing both the programs in C language. First I write a dummy process which will be the child process. What it is doing is only to write a string on the screen. It works well on its own. Then I write another program which will be the parent process. However, I can't make it happen. I'm trying to use fork and execl functions together, but I fail. I also want the child process does not terminate until the parent process terminates. How should I write the parent process? Thanks.

• How do Scala parser combinators compare to Haskell's Parsec?

  - by artif

  I have read that Haskell parser combinators (in Parsec) can parse context sensitive grammars. Is this also true for Scala parser combinators? If so, is this what the "into" (aka "") function is for? What are some strengths/weaknesses of Scala's implementation of parser combinators, vs Haskell's? Do they accept the same class of grammars? Is it easier to generate error messages or do other miscellaneous useful things with one or the other? How does packrat parsing (introduced in Scala 2.8) fit into this picture? Is there a webpage or some other resource that shows how different operators/functions/DSL-sugar from one language's implementation maps onto the other's?

• Can I align the text in a C# balloon tip ?

  - by John

  Hello, I wrote a little C# program that displays text in a balloon tip from time to time. When the text is in English, there's no problem : Everything is aligned to the left and is readable, but sometimes I have some Hebrew text and a left alignment of a RTL language gets all screwy. I was wondering if there's a way to right-align the Hebrew text ? Google pointed me to articles that can help me change the balloon color and font, but none of them have an alignment argument. Is it even possible ? Any help will be appropriated. John

• Different NSTimeZone names being returned

  - by Michael Waterfall

  I've noticed that on some devices the NSTimeZone's name method for a particular timezone can return different values. When testing the Brisbane time zone, my device returns @"Australia/Brisbane" whereas another user's device returns "Etc/GMT-10". Both iPhone's are running 3.1.2. The Date and Time Programming Guide for Cocoa states that: timeZoneWithName: The name passed to this method may be in any of the formats understood by the system, for example EST, Etc/GMT-2, America/Argentina/Buenos_Aires, Europe/Monaco, or US/Pacific, as shown in the following code fragment. I'd just like to know what could determine which value is used? The device? The language?

• How to use Netbeans platform syntax highlight with JEditorPane?

  - by Volta

  There are many tutorials online giving very complex or non-working examples on this. It seems that people recommend others to use the syntax highlighters offered by netbeans but I am totally puzzled on how to do so! I have checked many many sites on this and the best I can find is : http://www.antonioshome.net/kitchen/netbeans/nbms-standalone.php However I am still not able to use this example (as it is aimed to people who don't want to use the Netbeans platform but just a portion of it) and I am still not sure if I can just use syntax highlighting in a simple plug 'n play way. For example netbeans supports several language highlights by default, can I just use the highlighters in a JEditorPane to parse Ruby/Python/Java for example ? or do I need to write my own parser :-| ? I will really appreciate a small simple example on how to plug syntax highlight in a standalone application using the netbeans platform.

• TinyMCE: Double forecolor and backcolor buttons?

  - by petsson

  I'm having a problem using TinyMCE. In IE8, the forecolor and backcolor, for some random reason, is displayed twice. See picture below. Source code (I add the forecolor and backcolor in theme_advanced_buttons2): tinyMCE.init({ mode : "exact", elements : "<%= editArea.ClientID %>", custom_shortcuts : false, language : "en", relative_urls : false, convert_urls : false, forced_root_block : false, force_p_newlines : true, force_br_newlines : false, fix_nesting : true, plugins : "pagebreak,table", pagebreak_separator : '<div style="page-break-after:always;"></div>', theme : "advanced", skin : "o2k7", skin_variant : "blue", width : "540", height : "470", theme_advanced_toolbar_location : "top", theme_advanced_statusbar_location : "none", theme_advanced_font_sizes : "1,2,3,4,5,6,7", font_size_style_values : "0.6em,0.8em,1em,1.2em,1.5em,2em,3em", theme_advanced_buttons1 : "newdocument,|,copy,cut,paste,|,hr,pagebreak,|,undo,redo,|,code|,image,code", theme_advanced_buttons2 : "fontselect,fontsizeselect,|,bold,italic,underline,strikethrough,|,justifyleft,justifycenter,justifyright,justifyfull,|,forecolor,backcolor", // <-- This gives me double forecolor and backcolor theme_advanced_buttons3 : "table,|,row_props,cell_props,|,col_before,col_after,row_before,row_after,|,split_cells,merge_cells,|,delete_col,delete_row," });

• Using one LINQ statement with different parameters

  - by Brettski

  I have a pretty complex linq statement I need to access for different methods. Each of these methods may need to see the resulting data with different parameters. For one method it may be a project code, for another it may be language. The statement is pretty much the same it's just the where part which changes. I have not been able to figure out how to use different where statements without duplicating the entire linq statement, and that just isn't dry enough for me. For example (greatly simplified): var r = from c in customer where c.name == "some name" // or it may be var r = from c in customer where c.customerId == 8 Is there a way to have both of these in the same statement so I can use one or the other based on what I am doing? I tried an if statement to use one of the where statements or the other, and that didn't go over very well.

• Programming related name for a kitten? [closed]

  - by andrhamm

  I am a programmer and I just got my first kitten. A Google search for nerdy/geeky cat names was unimpressive. She's a little black kitten with a very courageous and adventurous attitude! She has a little light gray spot on her chest which might turn white with time. Here she is on my Flickr Which name would you suggest? Which of these do you like? It should be something short that has a couple contrasting sounds so it stands out a bit when you say it. PHP is my favorite scripting language but it makes for a lousy name :P Java Pixel Perl Ruby Gizmo Mocha Thanks for the help!

• In VB.NET how do you specify Inherits/implements on a generic class with multi-constraints

  - by Romel Evans

  When I write the following statement in VB.Net (C# is my normal language), I get an "end of statement expected" referring to the "Implements" statement. <Serializable()> _ <XmlSchemaProvider("EtgSchema")> _ Public Class SerializeableEntity(Of T As {Class, ISerializable, New}) _ Implements IXmlSerializable, ISerializable ... End Class The C# version that I'm trying to emulate is: [Serializable] [XmlSchemaProvider("MySchema")] public class SerializableEntity<T> : IXmlSerializable, ISerializable where T : class, new() { .... } Sometimes I feel like I have 5 thumbs with VB.NET :)

• linux user login/logout log for computer restriction

  - by Cedric

  Hi ! I would like to know how to log the login and logout of a user. I know it's possible to use the command "last". But this command is based on a file that has a r/w permission for the user, hence the possibility to change these data. I would like to log these data over two months. Why would I like to do that ? In fact, I would like to prevent a normal user to use a computer more than an hour a day - except week-ends, and 10 hours in total a week. Cedric System used : kubuntu, Programming language : bash script

• A tool to find and fix incomplete source code documentation

  - by Pekka

  I have several finished, older PHP projects with a lot of includes that I would like to document in javadoc/phpDocumentor style. While working through each file manually and being forced to do a code review alongside the documenting would be the best thing, I am, simply out of time constraints, interested in tools to help me automate the task as much as possible. The tool I am thinking about would ideally have the following features: Parse a PHP project tree and tell me where there are undocumented files, classes, and functions/methods (i.e. elements missing the appropriate docblock comment) Provide a method to half-way easily add the missing docblocks by creating the empty structures and, ideally, opening the file in an editor (internal or external I don't care) so I can put in the description. Optional: Automatic recognition of parameter types, return values and such. But that's not really required. The language in question is PHP, though I could imagine that a C/Java tool might be able to handle PHP files after some tweaking. Thanks for your great input!

• Detecting Infinite recursion in Python or dynamic languages

  - by drozzy

  Recently I tried compiling program something like this with GCC: int f(int i){ if(i<0){ return 0;} return f(i-1); and it ran just fine. When I inspected the stack frames the compiler optimized the program to use only one frame, by just jumping back to the beginning of the function and only replacing the arguments to f. And - the compiler wasn't even running in optimized mode. Now, when I try the same thing in Python - I hit maximum recursion wall (or stack overflow). Is there way that a dynamic language like python can take advantage of these nice optimizations? Maybe it's possible to use a compiler instead of an interpreter to make this work? Just curious!

• writing a fast parser in python

  - by panzi

  I've written a hands-on recursive pure python parser for a some file format (ARFF) we use in one lecture. Now running my exercise submission is awfully slow. Turns out by far the most time is spent in my parser. It's consuming a lot of CPU time, the HD is not the bottleneck. I wonder what performant ways are there to write a parser in python? I'd rather not rewrite it in C. I tried to use jython, but that decreased performance a lot! The files I parse are partially huge ( 150 MB) with very long lines. My current parser only needs a look-ahead of one character. I'd post the source here but I don't know if that's such a good idea. After all the submission deadline has not jet ended. But then, the focus in this exercise is not the parser. You can choose whatever language you want to use and there already is a parser for Java.

• Parsing Indentation-based syntaxes in Haskell's Parsec

  - by pavpanchekha

  I'm trying to parse an indentation-based language (think Python, Haskell itself, Boo, YAML) in Haskell using Parsec. I've seen the IndentParser library, and it looks like it's the perfect match, but what I can't figure out is how to make my TokenParser into an indentation parser. Here's the code I have so far: import qualified Text.ParserCombinators.Parsec.Token as T import qualified Text.ParserCombinators.Parsec.IndentParser.Token as IT lexer = T.makeTokenParser mylangDef ident = IT.identifier lexer This throws the error: parser2.hs:29:28: Couldn't match expected type `IT.TokenParser st' against inferred type `T.GenTokenParser s u m' In the first argument of `IT.identifier', namely `lexer' In the expression: IT.identifier lexer In the definition of `ident': ident = IT.identifier lexer What am I doing wrong? How should I create an IT.TokenParser? Or is IndentParser broken and to be avoided?

• pyopengl: Could it replace c++ ?

  - by Tom

  Hi everyone. I'm starting a computer graphics course, and I have to choose a language. Choices are between C++ and Python. I have no problem with C++, python is a work in progress. So i was thinking to go down the python road, using pyopengl for graphics part. I have heard though, that performance is an issue. Is python / pyopengl mature enough to challenge C++ on performance? I realize its a long shot, but I'd like to hear your thoughts, experiences on uses of pyopengl. Thanks in advance.

• Questions every good Java/J2EE Developer should be able to answer?

  - by Rachel

  I was going through Questions every good .Net developer should be able to answer and was highly impressed with the content and approach of this question, and so in the same spirit, I am asking this question for Java/J2EE Developer. What questions do you think should a good Java/J2EE programmer be able to answer? I am marking this question as community wiki as it is not user specific and it aims to serve programming community at large. Looking forward for some amazing responses. EDIT: Please answer questions too, as suggested in the comments, so that people could learn something new regarding the language, too.
