  • Windows Service Fails on Launch

    - by Jeff
    I'm trying to write a windows service. It installs fine, but fails when I run it with the following exception. I've searched for the string "MyNewProgramService", but I can't find any conversions that would throw this error. I've also added try/catch blocks to a bunch of code with custom exception handling without finding where this exception is occuring. I'm thinking it's somewhere in the auto-generated configuartion/setup code. Any ideas? Event Type: Error Event Source: MyNewProgram Event Category: None Event ID: 0 Date: 4/15/2010 Time: 12:48:34 PM User: N/A Computer: 20F7KF1 Description: Service cannot be started. System.InvalidCastException: Conversion from string "MyNewProgramService" to type 'Integer' is not valid. ---> System.FormatException: Input string was not in a correct format. at Microsoft.VisualBasic.CompilerServices.Conversions.ParseDouble(String Value, NumberFormatInfo NumberFormat) at Microsoft.VisualBasic.CompilerServices.Conversions.ToInteger(String Value) --- End of inner exception stack trace --- at Microsoft.VisualBasic.CompilerServices.Conversions.ToInteger(String Value) at TaskManagerFailureHandlerService.MyNewProgramService.OnStart(String[] args) at System.ServiceProcess.ServiceBase.ServiceQueuedMainCallback(Object state)

  • Hide header if node body is empty - Drupal php snippet help

    - by Toxid
    Hello! I've made a content type for links, I'm trying to make a link directory. People only have to submit the link, description is voluntary. If no description is entered, I want the header that says "description" to disappear. The description field is the node body. Right now my snippet looks like this <?php if (!empty($node->body)) {?> <div class="field field-type-link field-field-link-archive"> <h3>Description</h3> <?php print $node->content['body']['#value'] ?></div> <?php }?> I expect this to check if node body is not empty, and if it isn't it'll print what's there. The problem is that the Description header is still printed out even if the node body is empty. Can anyone see what's wrong?

  • How can I get jquery .val() AFTER keypress event?

    - by werner5471
    I got: $(someTextInputField).keypress(function() { alert($(this).val()); }); Now the alert always returns the value BEFORE the keypress (e.g. the field is empty, I type 'a' and the alert gives me ''. Then I type 'b' and the alert gives me 'a'...). But I want the value AFTER the keypress - how can I do that? Background: I'd like to enable a button as soon as the text field contains at least one character. So I run this test on every keypress event, but using the returned val() the result is always one step behind. Using the change() event is not an option for me because then the button is disabled until you leave the text box. If there's a better way to do that, I'm glad to hear it!

  • Call an action from another controller

    - by Brian
    I have two different objects: contracts, and task orders. My requirements specify that in order to view the Details for either object, the Url should be "http://.../Contract/Details" or "http://.../TaskOrder/Details" depending on which type. They are both very similar and the details pages are almost identical, so I made a class that can either be a contract or a task order, and has a variable "objectTypeID" that says which type it is. I wrote the action "Details" in the task order controller, but now I want to call that from the contract controller instead of recopying the code. So is there any way to have the url still say ".../Contract/Details" but call the action in the TaskOrder controller instead? I tried using TaskOrderController TOController = new TaskOrderController(); TOController.Details(id); This would have worked except that I can't use the HttpContext.Session anymore, which I used several times in the action.

  • Rails 3 respond_with, route constraints and resources

    - by Intelekshual
    I'm building a versioned API, so I have the following nested controllers: ApiController < ApplicationController Api::V1Controller < ApiController Api::V1::EventsController < Api::V1Controller The API is accessed via a subdomain. I have the following routes: constraints(:subdomain => "api") do scope :module => 'api' do namespace :v1 do resources :events end end end This produces the type of URL I want (/v1/events). The problem I'm facing is when using responds_with in Api::V1::EventsController. Just doing something as simple as the below fails with the error too few arguments: def index @events = Event.all respond_with(@events) end I know respond_width is meant to be used with resources, but I'm not sure how the events resource should be accessed from the constrained, scoped, and namespaced route. I can output other things (such as current_user), just not an array of events. Help?

  • How to use SynonymFilterFactory in Solr?

    - by AlxVallejo
    I'm trying to execute synonym filtering at query time so that if I search for X, results for Y also show up. I go to where Solr is being run, edit the .txt file and add X, Y on a new line. This does not work. I check the schema and I see: <analyzer type="query"> <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true" /> What am I missing? EDIT Assessing configuration files tomcat6/Catalina/localhost seems to point to the correct location <Context docBase="/data/solr/solr.war" debug="0" privileged="true" allowLinking="true" crossContext="true"> <Environment name="solr/home" type="java.lang.String" value="/data/solr" override="true" /> </Context> Also, in the Solr admin I see this. What does cwd mean? cwd=/usr/share/tomcat6 SolrHome=/data/solr/

  • .htaccess redirect question

    - by russp
    I have a slight problem with .htaccess redirect. I have a dynamic site with 2 levels of variables - content="type -(alpha)" and ID="number" but this is very not seo friendly what I really would like to create is a rewrite rule that generates a "friendly" url for serach engines & users alike. Very much like WordPress does. Each ID is already unique (obviously) and on creation is creating a unique "permalink" field so for example ID=1 has a "permalink field" as "2009/10/27/page title" and ID=100 would be "2010/10/27 page title". I would like folder/wall.php?content=type&ID=number to redirect to folder/permalink.php/html/htm (don't mind a non dynamic extension) Any clues? - this is not right (I know) but it also "breaks" my css file RewriteEngine On RewriteRule wall/content/(.*)/ID/(.*)/ wall.php?content=$1&ID=$2 RewriteRule wall/content/(.*)/ID/(.*) wall.php?content=$1&ID=$2

  • JSF/HTML - Add a Java applet to web page programmatically.

    - by Ben
    Theres a web page I'm making which content is very dynamic and so I'm building it from inside the backing bean. I would like to add a Java applet to the web page but I could not find the JSF component type to correspond to the <applet> tag. So My questions are - What is the JSF component type for an applet? How did you find it? (For similar future searches) Thanks! P.S - Just to be clear. An example: <h:PanelGroup> would be HtmlPanelGroup as a java object.

  • Data Annotations validation Built into model

    - by Josh
    I want to build an object model that automatically wires in validation when I attempt to save an object. I am using DataAnnotations for my validation, and it all works well, but I think my inheritance is whacked. I am looking here for some guidance on a better way to wire in my validation. So, to build in validation I have this interface public interface IValidatable { bool IsValid { get; } ValidationResponse ValidationResults { get; } void Validate(); } Then, I have a base class that all my objects inherit from. I did a class because I wanted to wire in the validation calls automatically. The issue is that the validation has to know the type of the class is it validating. So I use Generics like so. public class CoreObjectBase<T> : IValidatable where T : CoreObjectBase<T> { #region IValidatable Members public virtual bool IsValid { get { // First, check rules that always apply to this type var result = new Validator<T>().Validate((T)this); // return false if any violations occurred return !result.HasViolations; } } public virtual ValidationResponse ValidationResults { get { var result = new Validator<T>().Validate((T)this); return result; } } public virtual void Validate() { // First, check rules that always apply to this type var result = new Validator<T>().Validate((T)this); // throw error if any violations were detected if (result.HasViolations) throw new RulesException(result.Errors); } #endregion } So, I have this circular inheritance statement. My classes look like this then: public class MyClass : CoreObjectBase<MyClass> { } But the problem occurs when I have a more complicated model. Because I can only inherit from one class, when I have a situation where inheritance makes sense I believe the child classes won't have validation on their properties. public class Parent : CoreObjectBase<Parent> { //properties validated } public class Child : Parent { //properties not validated? } I haven't really tested the validation in these cases yet, but I am pretty sure that anything in child with a data annotation on it will not be automatically validated when I call Child.Validate(); due to the way the inheritance is configured. Is there a better way to do this?

  • [dynamic] Different behaviours between .NET 4.0 beta 2 and last release of .NET 4.0 !

    - by yogi4ever
    Hi. I've identified a difference of DLR between .NET 4.0 Beta 2 and the last release of .NET 4.0. In .NET 4.0 Beta 2, this code perfectly works at runtime : var dateTimeList = new List(); dynamic myDynamicObject = dateTimeList; object value = DateTime.Now; myDynamicObject.Add(value); Now, with last release of .NET 4.0, I have an exception at run time (to solve myDynamicObject.Add(value);) :-( In my real code, 'myDynamicObject' is a dynamic (but I know that it is always an ObservableCollection where T can be anything). 'value' is an instance which was got by some reflexions. As 'value' can have any type, the type of 'value' is Object. Do you see how can I solve this new limitation of .NET 4.0 ? Thanks

  • Execution sequence inside a jquery event handler

    - by user576358
    I have a big issue with the execution squence inside this jquery handler : Was wondering if anyone has come accross this before: I have a simple form: <form action='foo.cgi' id='myForm' > <input type=text name='name' /> <input type=submit value='Find it!'/> </form> when user clicks on Find it! would like to change the cursor to 'progress' before the data is returned through an ajax call: $(document).ready(function(){ $("#myForm ").submit(function(){ $("body").css("cursor", "progress") ; htmlobj=$.ajax({url:server_url,..........); } } However: The cursor [line 2 above ] does not change until data is returned through ajax - Seems like line 3. gets executed before 2. Any help is greatly appreciated

  • filter functions problem

    - by Adam
    I'm working on a search component for an app I'm working on and I needed to add some filters to it. I've found an example and got the first filter working fine. Now I'm trying to add a second filter I'm running into problems... In the example I found they use filterFunctions, but I only get an option for filterFunction, why is that? Here's the example code productsCollection.filterFunctions = [ filterByPrice, filterByType, filterByCondition, filterByVendor ] And this is what I'm trying acData.filterFunction = [filterByStatus, filterByDate] but with this code I get the following error message - 1067: Implicit coercion of a value of type Array to an unrelated type Function. Why am I getting this error and how would I go about add multiple filters to my Array Collection? Thanks!

  • R: How to separate character output in a loop?

    - by John
    I'm blanking on the best way to paste a list of strings together to go into an SQL statement... I'm having trouble with the separator bar | printing at the beginning when I don't want it to: foo = "blah" paste_all_together = NULL for (n in 1:4) { paste_together = paste(foo ,sep = "") paste_all_together = paste(paste_all_together, paste_together, sep = "|") } > paste_all_together [1] "|blah|blah|blah|blah" I just want it to print out "blah|blah|blah|blah". Do I need a nested loop, or is there a better itterator in R for doing this? Or perhaps a better way to input SQL statements?

  • Response.Redirect exception

    - by Tedd Hansen
    Executing the line: Response.Redirect("Whateva.aspx", true); Results in: A first chance exception of type 'System.Threading.ThreadAbortException' occurred in mscorlib.dll An exception of type 'System.Threading.ThreadAbortException' occurred in mscorlib.dll but was not handled in user code The exception is because of the "true" part, telling it to end the current request immediately. Is this how it should be? If we consider: Exceptions are generally considered heavy, and many times the reason for ending the request early is to avoid processing the rest of the page. Exceptions show up in performance monitoring, so monitoring the solution will show a false number of exceptions. Is there an alternative way to achieve the same?

  • Converting c++ string to int

    Hi! I have the following data in a c++ string John Doe 01.01.1970 I need to extract the date and time from it into int variables. I tried it like this: int last_space = text_string.find_last_of(' '); int day = int(text_string.substr(last_space + 1, 2)); But I got invalid cast from type ‘std::basic_string’ to type ‘int’. When I extract the "John Doe" part in another string variable, all works fine. What's wrong? I am trying to compile it with g++ -Wall -Werror.

  • python input for itertools.product

    - by user364249
    Looking for a way to simulate nested loops (or a cartesian product) i came across the itertools.product function. i need a function or piece of code that receive a list of integers as input and returns a specific generator. example: input = [3,2,4] - gen = product(xrange(3),xrange(2),xrange(4)) or input = [2,4,5,6] - gen = product(xrange(2),xrange(4),xrange(5),xrange(6)) as the size of the lists varies i am very confused in how to do that without the need of a lot of precoding based on a crazy amount of ifs and the size of the list. also is there a difference in calling product(range(3)) or product(xrange(3))?

  • How does Git know which Index blob to add to a tree?

    - by drozzy
    In Pro Git Ch9 the author says: Git normally creates a tree by taking the state of your staging area or index and writing a tree object from it. My question is how does git know which of two consequitive index entries to create the Tree object from? For example: $ echo 'First change' > one.txt $ git add one.txt $ find .git/objects -type f .git/objects/1f/755a7fffe4 //first index entry $ echo 'Second change' > one.txt $ git add one.txt $ find .git/objects -type f .git/objects/2d/234asdf2 //second index entry $ git commit -a -m "Initial commit" $ git cat-file master^{tree} 100644 blob 2d234asdf2 one.txt //How did it know not to take 1f755?? Does it just look at the blob timestamps? Also - what happens to the first blob created - no one is referencing it. Does it just get destroyed or forgotten?
