• How to get aspnet_Users.UserId for an anonymous user in ASP.NET membership ?

  - by Simon_Weaver

  I am trying to get the aspnet membership UserId field from an anonymous user. I have enabled anonymous identification in web.config : <anonymousIdentification enabled="true" /> I have also created a profile: <profile> <providers> <clear /> <add name="AspNetSqlProfileProvider" type="System.Web.Profile.SqlProfileProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" connectionStringName="ApplicationServices" applicationName="/" /> </providers> <properties> <add name="Email" type="System.String" allowAnonymous="true"/> <add name="SomethingElse" type="System.Int32" allowAnonymous="true"/> </properties> </profile> I see data in my aspnetdb\aspnet_Users table for anonymous users that have had profile information set. Userid PropertyNames PropertyValuesString 36139818-4245-45dd-99cb-2a721d43f9c5 Email:S:0:17: [email protected] I just need to find how to get the 'Userid' value. It is not possible to use : Membership.Provider.GetUser(Request.AnonymousID, false); The Request.AnonymousID is a different GUID and not equal to 36139818-4245-45dd-99cb-2a721d43f9c5. Is there any way to get this Userid. I want to associate it with incomplete activity for an anonymous user. Using the primary key of aspnet_Users is preferable to having to create my own GUID (which I could do and store in the profile). This is basically a dupe of this question but the question was never actually answered.

• refering Tomcat JNDI datasource in persistence.xml

  - by binary_runner

  in server.xml I've defined global resource (I'm using Tomcat 6): <GlobalNamingResources> <Resource name="jdbc/myds" auth="Container" type="javax.sql.DataSource" maxActive="10" maxIdle="3" maxWait="10000" username="sa" password="" driverClassName="org.h2.Driver" url="jdbc:h2:~/.myds/data/db" /> </GlobalNamingResources> I see in catalina.out that this is bound, so I suppose it's OK. In my web app I have the link to the datasource, I'm not sure it's OK: <Context> <ResourceLink global='jdbc/myds' name='jdbc/myds' type="javax.sql.Datasource"/> </Context> and in application there is persistence.xml : <persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd" version="2.0"> <persistence-unit name="oam" transaction-type="RESOURCE_LOCAL"> <provider>org.hibernate.ejb.HibernatePersistence</provider> <non-jta-data-source>jdbc/myds</non-jta-data-source> <!-- class definitions here, nothing else --> <properties> <property name="hibernate.dialect" value="org.hibernate.dialect.H2Dialect"/> </properties> </persistence-unit> </persistence> It shuld be OK, but most probably this or the ResourceLink definition is wrong because I'm getting: javax.naming.NameNotFoundException: Name jdbc is not bound in this Context What's wrong and why this does not work ?

• Reasons of getting a java.lang.VerifyError

  - by JeroenWyseur

  I'm investigating the following java.lang.VerifyError java.lang.VerifyError: (class: be/post/ehr/wfm/application/serviceorganization/report/DisplayReportServlet, method: getMonthData signature: (IILjava/util/Collection;Ljava/util/Collection;Ljava/util/HashMap;Ljava/util/Collection;Ljava/util/Locale;Lorg/apache/struts/util/MessageRe˜̴MtÌ´MÚw€mçw€mp:”MŒŒ at java.lang.Class.getDeclaredConstructors0(Native Method) at java.lang.Class.privateGetDeclaredConstructors(Class.java:2357) at java.lang.Class.getConstructor0(Class.java:2671) It occurs when the jboss server in which the servlet is deployed is started. It is compiled with jdk-1.5.0_11 and I tried to recompile it with jdk-1.5.0_15 without succes. That is the compilation runs fine but when deployed, the java.lang.VerifyError occurs. When I changed the methodname and got the following error: java.lang.VerifyError: (class: be/post/ehr/wfm/application/serviceorganization/r eport/DisplayReportServlet, method: getMD signature: (IILjava/util/Collection;Lj ava/util/Collection;Ljava/util/HashMap;Ljava/util/Collection;Ljava/util/Locale;L org/apache/struts/util/MessageResources-á+ÿ+àN|+ÿ+àN+Üw-Çm+ºw-ÇmX#+ûM|X+öM at java.lang.Class.getDeclaredConstructors0(Native Method) at java.lang.Class.privateGetDeclaredConstructors(Class.java:2357 at java.lang.Class.getConstructor0(Class.java:2671) at java.lang.Class.newInstance0(Class.java:321) at java.lang.Class.newInstance(Class.java:303) You can see that more of the method signature is shown. The actual method signature is private PgasePdfTable getMonthData(int month, int year, Collection dayTypes, Collection calendarDays, HashMap bcSpecialDays, Collection activityPeriods, Locale locale, MessageResources resources) throws Exception { I already tried looking to it with javap and that gives the method signature as it should be. When my other colleagues check out the code, compile it and deploy it, they have the same problem. When the build server picks up the code and deploys it on development or testing environments (HPUX), the same error occurs. Also an automated testing machine running ubuntu shows the same error during server startup. The rest of the application runs ok, only that one servlet is out of order. Any ideas where to look would be helpful.

• Is there a difference between plain text emails, and multipart emails with only plain text?

  - by Brian Armstrong

  I'm using Rails to send emails and I just want to send a plain text email (there is no corresponding HTML part). I've noticed that if I just have one file named email.text.plain.erb it actually generates a multipart email with one part (the plain text part) like this: Content-Type: multipart/alternative; boundary=mimepart_4c04a2d34c4bb_690a4e56b0362 --mimepart_4c04a2d34c4bb_690a4e56b0362 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: Quoted-printable Content-Disposition: inline text of the email here... --mimepart_4c04a2d34c4bb_690a4e56b0362-- But if I take out the text.plain part and name it email.erb ActionMailer generates a regular plain text email without multipart like this: Content-Type: text/plain; charset=utf-8 text of the email here... Both work fine most of the time (so this is kind of nitpicky), but I guess my question is whether the second one is more correct. My goal here is just to make sure deliverability is as high as possible across a wide variety of devices and email clients. I've read that plain text emails can have slightly better deliverability rates than html and was just curious if throwing in this multipart (even if it only contained a plain text part) might throw off some of the dumber email clients. Thanks for your help!

• Textbox autofill not in correct position in safari

  - by jerjer

  Hello All, Has anyone experience this weird issue on safari? Textbox autofill is not at its correct position, please see screenshot below. I have been searching for answers in google for almost a day, still no luck. This is the built-in autofill feature of safari. Here is the markup: index.php <html> <body> <div id="nav"></div> <div id="content"> <iframe style="width:100%;height:100%" src="add_user.php" frameborder="0"></iframe> </div> .... </body> </html> add_user.php <html> .... <body> <form method="post"> <h3>Add User (Admin only) <div id="msg">Please enter First and Last Name.</div> <ul> <li><label>* Email</label> <input type="text" id="email" /></li> <li><label>* First Name</label> <input type="text" id="fname" /></li> <li><label>* Last Name</label> <input type="text" id="lname" /></li> .... </ul> </form> </body> </html> I am suspecting that this is caused by the iframe, but it works just fine in other browsers. Also I could not change the page design(using iframe) right away for practical reasons. Thanks

• Improving Performance of Crystal Reports using Stored Procedures

  - by mjh41

  Recently I updated a Crystal Report that was doing all of its work on the client-side (Selects, formulas, etc) and changed all of the logic to be done on the server-side through Stored Procedures using an Oracle 11g database. Now the report is only being used to display the output of the stored procedures and nothing else. Everything I have read on this subject says that utilizing stored procedures should greatly reduce the running time of the report, but it still takes roughly the same amount of time to retrieve the data from the server. Is there something wrong with the stored procedure I have written, or is the issue in the Crystal Report itself? Here is the stored procedure code along with the package that defines the necessary REF CURSOR. CREATE OR REPLACE PROCEDURE SP90_INVENTORYDATA_ALL ( invdata_cur IN OUT sftnecm.inv_data_all_pkg.inv_data_all_type, dCurrentEndDate IN vw_METADATA.CASEENTRCVDDATE%type, dCurrentStartDate IN vw_METADATA.CASEENTRCVDDATE%type ) AS BEGIN OPEN invdata_cur FOR SELECT vw_METADATA.CREATIONTIME, vw_METADATA.RESRESOLUTIONDATE, vw_METADATA.CASEENTRCVDDATE, vw_METADATA.CASESTATUS, vw_METADATA.CASENUMBER, (CASE WHEN vw_METADATA.CASEENTRCVDDATE < dCurrentStartDate AND ( (vw_METADATA.CASESTATUS is null OR vw_METADATA.CASESTATUS != 'Closed') OR TO_DATE(vw_METADATA.RESRESOLUTIONDATE, 'MM/DD/YYYY') >= dCurrentStartDate) then 1 else 0 end) InventoryBegin, (CASE WHEN (to_date(vw_METADATA.RESRESOLUTIONDATE, 'MM/DD/YYYY') BETWEEN dCurrentStartDate AND dCurrentEndDate) AND vw_METADATA.RESRESOLUTIONDATE is not null AND vw_METADATA.CASESTATUS is not null then 1 else 0 end) CaseClosed, (CASE WHEN vw_METADATA.CASEENTRCVDDATE BETWEEN dCurrentStartDate AND dCurrentEndDate then 1 else 0 end) CaseCreated FROM vw_METADATA WHERE vw_METADATA.CASEENTRCVDDATE <= dCurrentEndDate ORDER BY vw_METADATA.CREATIONTIME, vw_METADATA.CASESTATUS; END SP90_INVENTORYDATA_ALL; And the package: CREATE OR REPLACE PACKAGE inv_data_all_pkg AS TYPE inv_data_all_type IS REF CURSOR RETURN inv_data_all_temp%ROWTYPE; END inv_data_all_pkg;

• Why doesn't jquery .load() load a text file from an external website?

  - by Edward Tanguay

  In the example below, when I click the button, it says "Load was performed" but no text is shown. I have a clientaccesspolicy.xml in the root directory and am able to asynchronously load the same file from silverlight. So I would think I should be able to access from AJAX as well. What do I have to change so that the text of the file http://www.tanguay.info/knowsite/data.txt is properly displayed in the #content element? <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <script type="text/javascript" src="http://www.google.com/jsapi"></script> <script type="text/javascript"> google.load("jquery", "1.3.2"); google.setOnLoadCallback(function() { $('#loadButton').click(loadDataFromExernalWebsite); }); function loadDataFromExernalWebsite() { $('#content').load('http://www.tanguay.info/knowsite/data.txt', function() { alert('Load was performed.'); }); } </script> </head> <body> <p>Click the button to load content:</p> <p id="content"></p> <input id="loadButton" type="button" value="load content"/> </body> </html>

• ASP.NET MVC Ajax.BeginForm eats params of submit button clicked. Looks like bug.

  - by RonnBlack

  If you are using Ajax.BeginForm() with multiple submit buttons similar to this: // View.aspx <% using (Ajax.BeginForm("Action", "Controller", new AjaxOptions { UpdateTargetId = "MyControl", })) { %> <span id="MyControl"> <% Html.RenderPartial("MyControl"); %> </span> <% } %> //MyControl.ascx <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %> <input name="prev" type="submit" value="prev" /> <input name="next" type="submit" value="next" /> //... Everything is submitted to the controller fine but the params for the submit button that was clicked are absent from the Request. In otherwords Request["next"] and Request["prev"] are always null. I looked in to the JavaScript in Microsoft.MvcAjax.js and it looks like the function Sys_Mvc_MvcHelpers$_serializeForm completely skips over the inputs that are of type 'submit'. This doesn't seem logical at all. How else can you find out what button has been clicked? It looks like a bug to me. Is there any logical reason to skip these form parameters?

• Sharepoint survey: How to identify the question fields when fetching survey information from the Lis

  - by paul

  I am wanting to access survey information via the Lists web service and display the questions contained in the survey. The result contains a large number of Field nodes some of which are the questions in the survey. The other fields contain other information such as author, last changed etc. How can I pick out the questions? I had thought that all non-questions would be hidden but this is not the case. Here is my code as it is at the moment. It returns about 16 items. The survey has 6 questions... // read question definitions string[] HandleTypes = new string[] { "Number", "DateTime", "Text", "Choice", "GridChoice", "Boolean" }; var query = from n in node.Descendants(ns+"Field") where (n.Attribute("Hidden") == null || n.Attribute("Hidden").Value.ToLower() == "true") && (n.Attribute("Type") != null && HandleTypes.Contains(n.Attribute("Type").Value)) select new Question(n.Attribute("ID").Value) { Text = n.Attribute("DisplayName").Value, QuestionType = n.Attribute("Type").Value, Element = n }; Ideas anyone?

• Workflow Foundation (WF) -- Why does setting a DependencyProperty to a COM object using SetValue() t

  - by stakx

  Assume that I have a .NET Workflow Foundation (WF) SequenceActivity class with the following property: public IWorkspace Workspace { get; set; } // ^^^^^^^^^^ // important: this is a COM interface type! public static DependencyProperty WorkspaceProperty = DependencyProperty.Register( "Workspace", typeof(IWorkspace), typeof(FoobarActivity)); // <-- this activity class This activity executes some code that sets both of the above like this: this.Workspace = ...; // exact code not relevant; property set to a COM object SetValue(WorkspaceProperty, this.Workspace); The last line (which makes the call to SetValue) results in an ArgumentException for the second parameter (having the value of this.Workspace): Type […].IWorkspace of dependency property Workspace does not match the value's type System.__ComObject.                                           (translated from German, the English exception text might differ slightly) As soon as I register the dependency property with typeof(object) instead of typeof(IWorkspace) as the second parameter, the code executes just fine. However, that would result in the possibility to assign just about any value to the dependency property, and I do not want that. It seems to me that WF dependency properties don't work for COM interop objects.Does anyone have a solution to this?

• Map enum in JPA with fixed values ?

  - by Kartoch

  I'm looking for the different ways to map an enum using JPA. I especially want to set the integer value of each enum entry and to save only the integer value. @Entity @Table(name = "AUTHORITY_") public class Authority implements Serializable { public enum Right { READ(100), WRITE(200), EDITOR (300); private int value; Right(int value) { this.value = value; } public int getValue() { return value; } }; @Id @GeneratedValue(strategy = GenerationType.AUTO) @Column(name = "AUTHORITY_ID") private Long id; // the enum to map : private Right right; } A simple solution is to use the Enumerated annotation with EnumType.ORDINAL: @Column(name = "RIGHT") @Enumerated(EnumType.ORDINAL) private Right right; But in this case JPA maps the enum index (0,1,2) and not the value I want (100,200,300). Th two solutions I found do not seem simple... First Solution A solution, proposed here, uses @PrePersist and @PostLoad to convert the enum to an other field and mark the enum field as transient: @Basic private int intValueForAnEnum; @PrePersist void populateDBFields() { intValueForAnEnum = right.getValue(); } @PostLoad void populateTransientFields() { right = Right.valueOf(intValueForAnEnum); } Second Solution The second solution proposed here proposed a generic conversion object, but still seems heavy and hibernate-oriented (@Type doesn't seem to exist in JEE): @Type( type = "org.appfuse.tutorial.commons.hibernate.GenericEnumUserType", parameters = { @Parameter( name = "enumClass", value = "Authority$Right"), @Parameter( name = "identifierMethod", value = "toInt"), @Parameter( name = "valueOfMethod", value = "fromInt") } ) Is there any other solutions ? I've several ideas in mind but I don't know if they exist in JPA: use the setter and getter methods of right member of Authority Class when loading and saving the Authority object an equivalent idea would be to tell JPA what are the methods of Right enum to convert enum to int and int to enum Because I'm using Spring, is there any way to tell JPA to use a specific converter (RightEditor) ?

• Character Encoding: â??

  - by akaphenom

  I am trying to piece together the mysterious string of characters â?? I am seeing quite a bit of in our database - I am fairly sure this is a result of conversion between character encodings, but I am not completely positive. The users are able to enter text (or cut and paste) into a Ext-Js rich text editor. The data is posted to a severlet which persists it to the database, and when I view it in the database i see those strange characters... is there any way to decode these back to their original meaning, if I was able to discover the correct encoding - or is there a loss of bits or bytes that has occured through the conversion process? Users are cutting and pasting from multiple versions of MS Word and PDF. Does the encoding follow where the user copied from? Thank you website is UTF-8 We are using ms sql server 2005; SELECT serverproperty('Collation') -- Server default collation. Latin1_General_CI_AS SELECT databasepropertyex('xxxx', 'Collation') -- Database default SQL_Latin1_General_CP1_CI_AS and the column: Column_name Type Computed Length Prec Scale Nullable TrimTrailingBlanks FixedLenNullInSource Collation text varchar no -1 yes no yes SQL_Latin1_General_CP1_CI_AS The non-Unicode equivalents of the nchar, nvarchar, and ntext data types in SQL Server 2000 are listed below. When Unicode data is inserted into one of these non-Unicode data type columns through a command string (otherwise known as a "language event"), SQL Server converts the data to the data type using the code page associated with the collation of the column. When a character cannot be represented on a code page, it is replaced by a question mark (?), indicating the data has been lost. Appearance of unexpected characters or question marks in your data indicates your data has been converted from Unicode to non-Unicode at some layer, and this conversion resulted in lost characters. So this may be the root cause of the problem... and not an easy one to solve on our end.

• "import numpy" tries to load my own package

  - by Sebastian

  I have a python (2.7) project containing my own packages util and operator (and so forth). I read about relative imports, but perhaps I didn't understand. I have the following directory structure: top-dir/ util/__init__.py (empty) util/ua.py util/ub.py operator/__init__.py ... test/test1.py The test1.py file contains #!/usr/bin/env python2 from __future__ import absolute_import # removing this line dosn't change anything. It's default functionality in python2.7 I guess import numpy as np It's fine when I execute test1.py inside the test/ folder. But when I move to the top-dir/ the import numpy wants to include my own util package: Traceback (most recent call last): File "tests/laplace_2d_square.py", line 4, in <module> import numpy as np File "/usr/lib/python2.7/site-packages/numpy/__init__.py", line 137, in <module> import add_newdocs File "/usr/lib/python2.7/site-packages/numpy/add_newdocs.py", line 9, in <module> from numpy.lib import add_newdoc File "/usr/lib/python2.7/site-packages/numpy/lib/__init__.py", line 4, in <module> from type_check import * File "/usr/lib/python2.7/site-packages/numpy/lib/type_check.py", line 8, in <module> import numpy.core.numeric as _nx File "/usr/lib/python2.7/site-packages/numpy/core/__init__.py", line 45, in <module> from numpy.testing import Tester File "/usr/lib/python2.7/site-packages/numpy/testing/__init__.py", line 8, in <module> from unittest import TestCase File "/usr/lib/python2.7/unittest/__init__.py", line 58, in <module> from .result import TestResult File "/usr/lib/python2.7/unittest/result.py", line 9, in <module> from . import util File "/usr/lib/python2.7/unittest/util.py", line 2, in <module> from collections import namedtuple, OrderedDict File "/usr/lib/python2.7/collections.py", line 9, in <module> from operator import itemgetter as _itemgetter, eq as _eq ImportError: cannot import name itemgetter The troublesome line is either from . import util or perhaps from operator import itemgetter as _itemgetter, eq as _eq What can I do?

• Blackberry MDS simulator - Can't connect to the internet in the simulator.

  - by bcoyour

  I'm trying to do some testing of a website through the Blackberry simulator, while the simulator works fine, I can't get to any sites in the Blackberry Browser. Here is the specific setup I'm using. I'm Windows 7 (64-bit) Home Edition I have the latest (at the time) MDS installation - BlackBerry Email and MDS Services Simulators 4.1.4 Finally, I have the latest (at the time) Blackberry Simulator - BlackBerry Smartphone Simulators 5.0.0 (5.0.0.442) - 9700 I first start the MDS service, it briefly pops up the command-prompt and then closes it. I'm assuming that when it does that, it started the MDS service. Then I open the Blackberry simulator (9700), which opens up fine and loads the Blackberry OS. Then with the Blackberry OS all loaded up, I navigate to the browser and for example type www.google.com and then at the bottom it just says "sending request" and loads for about a minute. Then times out and says it can't find a connection. Anyone have any thoughts on what I'm missing? Or, does anyone know of an online simulator for the Blackberry, because thus far this has been a huge pain for testing sites on a Blackberry. Thank you! Ben

• HTML - Correct way of coding a checkbox with a Label.

  - by egarcia

  I've been using formtastic in order to generate HTML forms on rails applications. My question, however, is really HTML-related. Today I found a strange behaviour on the way formtastic generates checkboxes (fields of type :boolean on formtastic lingo). The rest of the fields (non-checkboxes) are generated this way: <li> <label for="my_textbox_field">My TextBox</label> <input id="my_textbox_field" type="text" ... > </li> Checkboxes, however, are enclosed inside their <label> tags completely - like this: <li> <label for="my_boolean_field"> <input id="my_boolean_field" type="checkbox" ... > This is my boolean field </label> </li> Formtastic phylosophy seems to be based on the Learning to Love Forms presentation. In effect, on slide 36 of that presentation this structure is suggested for checkboxes. I guess in the presentation itself the presenter explained why this was done, but it is not written on the slides. Can anyone tell me why enclosing checkboxes inside their <label> tag might be a good idea, as opposed to putting them outside, like with textboxes?

• Style Trigger on Attached Property

  - by vanja.

  I have created my own Attached Property like this: public static class LabelExtension { public static bool GetSelectable(DependencyObject obj) { return (bool)obj.GetValue(SelectableProperty); } public static void SetSelectable(DependencyObject obj, bool value) { obj.SetValue(SelectableProperty, value); } // Using a DependencyProperty as the backing store for Selectable. This enables animation, styling, binding, etc... public static readonly DependencyProperty SelectableProperty = DependencyProperty.RegisterAttached("Selectable", typeof(bool), typeof(Label), new UIPropertyMetadata(false)); } And then I'm trying to create a style with a trigger that depends on it: <!--Label--> <Style TargetType="{x:Type Label}"> <Style.Triggers> <Trigger Property="Util:LabelExtension.Selectable" Value="True"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type Label}"> <TextBox IsReadOnly="True" Text="{TemplateBinding Content}" /> </ControlTemplate> </Setter.Value> </Setter> </Trigger> </Style.Triggers> </Style> But I'm getting a run time exception: Cannot convert the value in attribute 'Property' to object of type 'System.Windows.DependencyProperty'. Error at object 'System.Windows.Trigger' in markup file How can I access the value of the attached property in a style trigger? I have tried using a DataTrigger with a RelativeSource binding but it wasn't pulling the value through.

• Visual Studio 2008 project organization for executable and assembly

  - by user304582

  Hi - I am having a problem setting up the following in Visual Studio 2008: a parent project which includes the entrypoint Main() method class and which declares an interface, and a child project which has classes that implement the interface declared in the parent project. I have specified that Parent's Output type is a Console application, and Child's Output type is a Class library. In Child I have add a reference to the Parent as a project, and specified that Child depends on Parent and that the build order should be Parent, then Child. The build succeeds, and as far I can tell, the right things show up in the Child/bin/debug directory: Parent.exe and Child.dll. However, if I run Parent.exe, then at the point when it should load a class from the Child.dll, it fails with the error message: exception executing operation System.TypeLoadException: Could not load type 'Child.some.class' from assembly 'Parent, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'. I guess I'm confused as to how to get the Parent and Child projects to play together. I plan on having more child projects that use the same framework that is set up in the Parent, and so I do not want to move the entrypoint class down into the Child project. If I try to specify that the Child project is also a Console application, then the build process fails because there is no Main() entrypoint class in the child (even though the Parent project is included as a reference). Any help would be welcome! Thanks, Martin

• Accessing Item Fields via Sitecore Web Service

  - by Catch

  I am creating items on the fly via Sitecore Web Service. So far I can create the items from this function: AddFromTemplate And I also tried this link: http://blog.hansmelis.be/2012/05/29/sitecore-web-service-pitfalls/ But I am finding it hard to access the fields. So far here is my code: public void CreateItemInSitecore(string getDayGuid, Oracle.DataAccess.Client.OracleDataReader reader) { if (getDayGuid != null) { var sitecoreService = new EverBankCMS.VisualSitecoreService(); var addItem = sitecoreService.AddFromTemplate(getDayGuid, templateIdRTT, "Testing", database, myCred); var getChildren = sitecoreService.GetChildren(getDayGuid, database, myCred); for (int i = 0; i < getChildren.ChildNodes.Count; i++) { if (getChildren.ChildNodes[i].InnerText.ToString() == "Testing") { var getItem = sitecoreService.GetItemFields(getChildren.ChildNodes[i].Attributes[0].Value, "en", "1", true, database, myCred); string p = getChildren.ChildNodes[i].Attributes[0].Value; } } } } So as you can see I am creating an Item and I want to access the Fields for that item. I thought that GetItemFields will give me some value, but finding it hard to get it. Any clue?

• Changing App.config at Runtime

  - by born to hula

  I'm writing a test winforms / C# / .NET 3.5 application for the system we're developing and we fell in the need to switch between .config files at runtime, but this is turning out to be a nightmare. Here's the scene: the Winforms application is aimed at testing a WebApp, divided into 5 subsystems. The test proccess works with messages being sent between the subsystems, and for this proccess to be sucessful each subsystem got to have its own .config file. For my Test Application I wrote 5 separate configuration files. I wish I was able to switch between these 5 files during runtime, but the problem is: I can programatically edit the application .config file inumerous times, but these changes will only take effect once. I've been searching a long time for a form to address this problem but I still wasn't sucessful. I know the problem definition may be a bit confusing but I would really appreciate it if someone helped me. Thanks in advance! --- UPDATE 01-06-10 --- There's something I didn't mention before. Originally, our system is a Web Application with WCF calls between each subsystem. For performance testing reasons (we're using ANTS 4), we had to create a local copy of the assemblies and reference them from the test project. It may sound a bit wrong, but we couldn't find a satisfying way to measure performance of a remote application. --- End Update --- Here's what I'm doing: public void UpdateAppSettings(string key, string value) { XmlDocument xmlDoc = new XmlDocument(); xmlDoc.Load(AppDomain.CurrentDomain.SetupInformation.ConfigurationFile); foreach (XmlElement item in xmlDoc.DocumentElement) { foreach (XmlNode node in item.ChildNodes) { if (node.Name == key) { node.Attributes[0].Value = value; break; } } } xmlDoc.Save(AppDomain.CurrentDomain.SetupInformation.ConfigurationFile); System.Configuration.ConfigurationManager.RefreshSection("section/subSection"); }

• JavaScript To Clear Form Field On Submit Before Form Submission To Perl Script

  - by Russell C.

  We have a very long form that has a number of fields and 2 different submit buttons. When a user clicks the 1st submit button ("Photo Search") the form should POST and our script will do a search for matching photos based on what the user entered in the text input ("photo_search_text") next to the 1st submit button and reload the entire form with matching photos added to the form. Upon clicking the 2nd submit button ("Save Changes") at the end of the form, it should POST and our script should update the database with the information the user entered in the form. Unfortunately the layout of the form makes it impossible to separate it into 2 separate forms. I checked the entire form POST and unfortunately the submitted fields are identical to the perl script processing the form submission no matter which submit button is clicked so the perl script can't differentiate which action to perform based on which submit button is pushed. The only thing I can think of is to update the onclick action of the 2nd submit button so it clears the "photo_search_text" field before the form is submitted and then only perform a photo search if that fields has a value. Based on all this, my question is what does the JavaScript look that could clear out the "photo_search_text" field when someone clicks on the 2nd submit button? Here is what I've tried so far none of which has worked successfully: <input type="submit" name="submit" onclick="document.update-form.photo_search_text.value='';" value="Save Changes"> <input type="submit" name="submit" onsubmit="document.update-form.photo_search_text.value='';" value="Save Changes"> <input type="submit" name="submit" onclick="document.getElementById('photo_search_text')='';" value="Save Changes"> We also use JQuery on the site so if there is a way to do this with jQuery instead of plain JavaScript feel free to provide example code for that instead. Lastly, if there is another way to handle this that I'm not thinking of any and all suggestions would be welcome. Thanks in advance for your help!

• jquery access sibling TD in table

  - by Rob

  I have the following HTML Code. What I'm try to do is to have the div named javaRatingDiv to be displayed once the checkbox with the name java is checked. I can't seem to figure out how to navigate to the next TD in a table via jquery. <div id="languages"> <table style="width:inherit"> <tr style="height:50px; vertical-align:top"> <td>Select the languages that you are familiar with and rate your knowledge:</td> </tr> <tr> <table style="width:75%;" align="center"> <tr id="tableRow"> <td id="firstTD"><input type="checkbox" name="java" value="java" />&nbsp;Java</td> <td id="secondTD" style="width:200px;"> <div id="javaRatingDiv" style="display:none"> <input name="javaRating" type="radio" value="1" class="star"/> <input name="javaRating" type="radio" value="2" class="star"/> </div> </td> </tr> </table> </tr> </table> </div>

• Using datetime float representation as primary key

  - by devanalyst

  From my experience I have learn that using an surrogate INT data type column as primary key esp. an IDENTITY key column offers better performance than using GUID or char/varchar data type column as primary key. I try to use IDENTITY key as primary key wherever possible. But recently I came across a schema where the tables were horizontally partitioned and were managed via a Partitioned view. So the tables could not have an IDENTITY column since that would make the Partitioned View non updatable. One work around for this was to create a dummy 'keygenerator' table with an identity column to generate IDs for primary key. But this would mean having a 'keygenerator' table for each of the Partitioned View. My next thought was to use float as a primary key. The reason is the following key algorithm that I devised DECLARE @KEY FLOAT SET @KEY = CONVERT(FLOAT,GETDATE())/100000.0 SET @KEY = @EMP_ID + @KEY Heres how it works. CONVERT(FLOAT,GETDATE()) gives float representation of current datetime since internally all datetime are represented by SQL as a float value. CONVERT(FLOAT,GETDATE())/100000.0 converts the float representation into complete decimal value i.e. all digits are pushed to right side of ".". @KEY = @EMP_ID + @KEY adds the Employee ID which is an integer to this decimal value. The logic is that the Employee ID is guaranteed to be unique across sessions since an employee cannot connect to an application more than once at the same time. And for the same employee each time a key will be generated the current datetime will be unique. In all an unique key across all employee sessions and across time. So for Emp Ids 11 and 12, I have key values like 12.40046693321566357, 11.40046693542361111 But my concern whether float data type as primary key offer benefits compared to choosing GUID or char/varchar as primary keys. Also important thing is because of partitioning the float column is going to be part of a composite key.

• How to generate comments in hbm2java created POJO?

  - by jschoen

  My current setup using hibernate uses the hibernate.reveng.xml file to generate the various hbm.xml files. Which are then turned into POJOs using hbm2java. We spent some time while designing our schema, to place some pretty decent descriptions on the Tables and there columns. I am able to pull these descriptions into the hbm.xml files when generating them using hbm2jhbmxml. So I get something similar to this: <class name="test.Person" table="PERSONS"> <comment>The comment about the PERSONS table.</comment> <property name="firstName" type="string"> <column name="FIRST_NAME" length="100" not-null="true"> <comment>The first name of this person.</comment> </column> </property> <property name="middleInitial" type="string"> <column name="MIDDLE_INITIAL" length="1"> <comment>The middle initial of this person.</comment> </column> </property> <property name="lastName" type="string"> <column name="LAST_NAME" length="100"> <comment>The last name of this person.</comment> </column> </property> </class> So how do I tell hbm2java to pull and place these comments in the created Java files? I have read over this about editing the freemarker templates to change the way code is generated. I under stand the concept, but it was not to detailed about what else you could do with it beyond there example of pre and post conditions.

• Multiple undo managers for a text view

  - by Rui Pacheco

  Hi, I've a text view that gets its content from an attributed string stored in a model object. I list several of these model objects in a drawer and when the user clicks on one the text view swaps its content. I now need to also swap the undo manager for the text view. I initialise an undo manager on my model object and use undoManagerForTextView to return it to the text view, but something's not quite right. Strategically placed logging statements show me that everything's working as planned: on startup a new model object is initialised correctly and a non-null undo manager is always pulled by the text view. But when it comes to actually doing undo, I just can't get the behaviour I want. I open a window, type something and press cmd+z, and undo works. I open a window, type something, select a new model on the table, type something, go back to the first model and try to undo and all I get is a beep. Something on the documentation made me raise an eyebrow, as it would mean that I can't have undo with several model objects: The default undo and redo behavior applies to text fields and text in cells as long as the field or cell is the first responder (that is, the focus of keyboard actions). Once the insertion point leaves the field or cell, prior operations cannot be undone.
