• Is there a JSON parser for VB6 / VBA?

  - by Ben McCormack

  I'm trying to consume a web service in VB6. The service (which I control) currently can return a SOAP/XML message or JSON. I'm having a really difficult time figuring out if VB6's SOAP type (version 1) can handle a returned object (as opposed to simple types like string, int, etc.). So far I can't figure out what I need to do to get VB6 to play with returned objects. So I thought I might serialize the response in the web service as a JSON string. Does a JSON parser exist for VB6?

• events not firing in VisualForce

  - by Ben

  In the page below,Topic__c is a single-select picklist. My intention is to have this list control which of the input fields is available below. The user selects an option, and the onchange event should fire, and rerender the fields. <apex:inputField value="{!Call_Report__c.Topic__c}" id="topic" > <apex:actionSupport event="onchange" reRender="tickerInput,sectorInput,bondInput"> <apex:param name="topicSelection" value="{!Call_Report__c.Topic__c}" /> </apex:actionSupport> </apex:inputField> <apex:inputField value="{!Call_Report__c.Tickers__c}" rendered="{!Call_Report__c.Topic__c='Issuer'}" id="tickerInput" /> <apex:inputField value="{!Call_Report__c.Sector__c}" rendered="{!Call_Report__c.Topic__c='Industry'}" id="sectorInput"/> <apex:inputField value="{!Call_Report__c.Security__c}" rendered="{!Call_Report__c.Topic__c='Specific Bond'}" id="bondInput" /> Am I doing something obviously wrong here? http://community.salesforce.com/t5/Visualforce-Development/Multi-select-picklist-not-firing-event-for-AJAX-refreshes/m-p/173572/highlight/false#M22119 seems to imply that what I am doing is reasonable...

• location.hash in an iframe scrolls the parent window

  - by Ben Clayton

  Hi all. I have a page with an iframe. Inside the iframe is code (that I can't change) that sets location.hash to the id of an element in the iframe window. This has the unwanted effect of scrolling my outermost browser window so that the top of the window touches the top of the iframe. This is quite annoying as I have a toolbar above the iframe that is vital to my app. Is there any way of preventing the setting of location.hash affecting the scroll position of the main window? Will preventDefault help me out here? Thanks!

• Use Maven to trigger a wsgen & wsimport in a row, using wsdlLocation

  - by ben

  I have hard times using maven to generate my client. So Please refer to http://stackoverflow.com/questions/2131001/creating-a-web-service-client-directly-from-the-source for the first part of my question. To keep it simple and short, I want to go from here (a file in src/main/java) : package com.example.maven.jaxws.helloservice; import javax.jws.WebService; @WebService public class Hello { public String sayHello(String param) { ; return "Hello " + param; } } to there : /** * This class was generated by the JAX-WS RI. * JAX-WS RI 2.1.7-b01- * Generated source version: 2.1 * */ @WebServiceClient(name = "HelloService", targetNamespace = "http://helloservice.jaxws.maven.example.com/", wsdlLocation = "http://localhost:8080/test/") public class HelloService extends Service { private final static URL HELLOSERVICE_WSDL_LOCATION; private final static Logger logger = Logger.getLogger(com.example.wsimport.HelloService.class.getName()); ...etc using only 1 pom.xml file. Please note the wsdlLocation set on the end. The pom.xml file will probably use both maven-jaxws-plugin wsgen AND wsimport with some tricky configuration to achieve this.

• How to populate object dependencies with routing bapi

  - by Ben V

  I'm using BAPI_ROUTING_CREATE to interface routing creation/changes from an external system. There doesn't seem to be a way to pass VC object dependencies for each operation. Does anyone know of a way to programmatically update object dependencies? I'd prefer to avoid BDCs if possible.

• Entity Relationship Diagramming

  - by Ben Aston

  I'd like to improve my understanding of cardinality constraints in ER diagrams. I have two entities: User Location But, I want the relationship between these two entities to be many-to-many (a user can be in many locations and a location can have many users). To do this I need to introduce an association class UserLocation. Is it correct to say I now have 3 entities? If I were to draw an ER diagam of the above, would I draw in the UserLocation entity, and would the cardinality look like this? User 1 ------ * User Location * ------ 1 Location

• exception with Linq to SQL using sdf file

  - by Ben

  Hi, I've set up a project with an SDF local database file and am trying to access it using an LINQ To SQL (".dbml") file. I have used the connection string provided by the sdf file and can instanciate the object with out a problem: thisDataContext = new MyDataContext(GetConnectionString()); However, whenever i try to access any information from it eg var collection = (from MyObject p in thisDataContext.MyTable select p); I get the error - "The table name is not valid. [ Token line number (if known) = 2,Token line offset (if known) = 14,Table name = Person ]" I am using Visual Studio 2008 SP1 .Net 3.5 and SQL 2008 CE. I gather something similar happened for SQL 2005 CE and a Hotfix was released, but i would have thought the fix would have been fixed in this version before release. Does anyone know the fix for this? Thanks

• How are Wordpress plugins differentiated by Wordpress

  - by Ben Jackson

  I have created a wordpress plugin and uploaded it to my test site, but under Plugins wordpress informs me that there is update available to my plugin and it takes me to a completely separate plugin on wordpress.org Why is wordpress confusing them? How are plugins differentiated from each other as unique? Should I have a unique code or something? What is it in my plugin which is the same as the plugin Wordpress is confusing it with?

• what is this internet explorer (javascript?) syntax error -2146827286?

  - by ben

  Hi everyone, So, I've been trying to troubleshoot this bug where some big percentage of windows users who are on my ajax (jquery) web app are not able to play. I haven't been able to reproduce it on my end with a windows 7 IE8 running in a parallels vm. The main problem seems to be in the javascript somewhere because what users are complaining about is an ajax button isn't working. They click it and nothing happens, so either the event isn't firing, or my ajax call is failing, and possibly the return from the ajax could be failing. After trying some ideas, a friend suggested I check out damnit! https://damnit.jupiterit.com/ which will catch exceptions in javascript and email them to you. This is a pretty awesome tool! So, now i have a little more data, but, am stuck. Basically it seems like the majority of the exceptions seem to be complaining about a syntax error. I will paste the samples below. message: Syntax error number: -2146827286 description: Syntax error Browser: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729; InfoPath.2; .NET CLR 1.0.3705; OfficeLiveConnector.1.3; OfficeLivePatch.0.0) What's interesting is that the syntax error is consistently occurring in browsers reporting MSIE 8.0 but with windows vista, xp, and below, so older OS with the latest IE. Does anyone know of this error? Could this possibly be some weird slow computer/slow internet connection thing where may be my javascript files aren't fully loaded before I call the functions. I am using the jquery $(document).ready() to wait before I setup anything.

• Mercurial over ssh client and server on Windows

  - by Ben Von Handorf

  I'm trying to configure Mercurial for use with both a windows server (freeSSHd) and client (both command line and TortoiseHG). I'm using the most recent versions of everything... all downloaded in the past few days. Using public key auth, I have been able to get connected to the server and I'm able to use plink to execute "hg version" and get a response, but when I try to clone a repository from the ssh server the command appears to hang. Running with -v yields: hg -v clone ssh://<username>@<server>//hg/repositoryA testRepositoryA running "plink.exe -i "<path to private key file>" <username>@<server> "hg -R /hg/repositoryA serve --stdio"" with nothing more forthcoming. Running the hg serve command directly on the server yields an apparently responsive Mercurial server, but the clients do not seem to make any further requests. Running "hg serve" in the repository directory and cloning over http works perfectly. What should I be looking for to help debug this? Is there something the clients (hg and TortoiseHG) aren't sending to continue the request stream? Additional Information: If I change to an invalid repository on the target machine, the appropriate error is displayed, so it does appear that the remote hg is running and correctly evaluating the path. Running with --debug and --traceback results in: sending hello command sending between command It hangs here, until I CTRL-C Traceback (most recent call last): File "mercurial\dispatch.pyo", line 46, in _runcatch File "mercurial\dispatch.pyo", line 452, in _dispatch File "mercurial\dispatch.pyo", line 320, in runcommand File "mercurial\dispatch.pyo", line 504, in _runcommand File "mercurial\dispatch.pyo", line 457, in checkargs File "mercurial\dispatch.pyo", line 451, in <lambda> File "mercurial\util.pyo", line 402, in check File "mercurial\commands.pyo", line 636, in clone File "mercurial\hg.pyo", line 187, in clone File "mercurial\hg.pyo", line 63, in repository File "mercurial\sshrepo.pyo", line 51, in __init__ File "mercurial\sshrepo.pyo", line 73, in validate_repo KeyboardInterrupt interrupted! Responding to Ryan: There does not appear to be any CPU usage or increasing memory usage on the server. It appears to be waiting for the client to send a request or something similar. 11/19/2009 : More information: The problem is definitely in the freeSSHd/server side of the equation. Connecting to bitbucket over ssh with the same keyset works fine. Still working on this.

• What happens when I subscribe to a message using NServiceBus?

  - by Ben Aston

  When I subscribe as the recipient of a certain type of message using NServiceBus Bus.Subscribe<MyMessage>() What am I actually doing? Am I specifying that a particular method on the recipient type will be invoked upon message receipt? If so, within what context does the method run - in a static context, or within the context of a new'd-up parent class instance (and if so, how does NServiceBus know what constructor to use)?

• Click event keeps firing

  - by Ben Shelock

  I have absolutely no idea why this is happening but the following code seems to be executed a huge ammount of times in all browsers. $('#save_albums').click(function(){ for(var i = 1; i <= 5; i++){ html = $('#your_albums ol li').eq(i).html(); alert(html); } }); Looks fairly innocent to me... Here's the code in it's entirety $(function(){ $('#query').keyup(function(){ var text = encodeURI($(this).val()); if(text.length > 3){ $('#results').load('search.php?album='+text, function(){ $('.album').hover(function(){ $(this).css('outline', '1px solid black') },function(){ $(this).css('outline', 'none') }); $('.album').click(function(){ $('#fores').remove(); $('#yours').show(); if($('#your_albums ol li').length <= 4){ albumInfo = '<li><div class="album">' + $(this).html() + '</div></li>'; if($('#your_albums ol li').length >= 1){ $('#your_albums ol li').last().after(albumInfo); } else{ $('#your_albums ol').html(albumInfo); } } else{ alert('No more than 5 please'); } }); $('#clear_albums').click(function(e){ e.preventDefault; $('#your_albums ol li').remove(); }); $('#save_albums').click(function(){ for(var i = 1; i <= 5; i++){ html = $('#your_albums ol li').eq(i).html(); alert(html); } }); }); } else{ $('#results').text('Query must be more than 3 characters'); } }); });

• How do I make a form modal in Windows Forms?

  - by Ben McCormack

  I'm trying to create a child form that helps the user to enter data for a field in the parent form. I want this child form to be modal, but I don't know what I need to do to make this form modal. Perhaps there's a different type of item I need to use; if so, let me know.

• database splitting; multiple tables

  - by Ben

  I am coding a classifieds ad web app. What is the optimal way to structure the database for this? Because of the high repeatability, would it be faster (in terms of searching/indexing) to have a separate table in the database for each city? Or would it be okay to just have one table for every city (it would have a lot of rows..). The classifieds table has id, user_id, city_name, category,[description and detail fields].

• Script tag in XHTML

  - by Ben

  Hi, This might sound like a reaaaally dumb question but... why do browsers have a fit with this syntax: <script type='text/javascript' src="/path/to/my.js" /> and want this instead <script type='text/javascript' src="/path/to/my.js"></script> Seems the first construct should be valid since there's no inner content to the tag.. ?

• Fragment Shader Eye-Space unscaled depth coordinate

  - by Ben Jones

  I'm trying to use the unscaled (true distance from the front clipping plane) distance to objects in my scene in a GLSL fragment shader. The gl_FragCoord.z value is smaller than I expect. In my vertex shader, I just use ftransform() to set gl_Position. I'm seeing values between 2 and 3 when I expect them to be between 15 and 20. How can I get the real eye-space depth? Thanks!

• extjs - center a formPanel on a normal panel

  - by Ben

  Hi there, I'm using extjs and just trying to solve a simple problem: I have a form with a fixed width. I want to Center this form within a normal Ext.Panel. I'm trying to achieve this the 'css-way' - setting the left and right margin to 'auto'. But this doesn' work, it seems the margins are just ignored. The Code: var curStateForm = new Ext.FormPanel({ title:'test', width:300, bodyStyle:'margin:5px auto 0 auto', items: [edIst, edAdjust, edSumme] }); var testPanel = new Ext.Panel({ width: '100%', frame:true, items:[curStateForm] }); Thx to all!

• How do I set the ItemsSource of a DataGrid in XAML?

  - by Ben McCormack

  I'm trying to set the ItemsSource property of a DataGrid named dgIssueSummary to be an ObservableCollection named IssueSummaryList. Currently, everything is working when I set the ItemsSource property in my code-behind: public partial class MainPage : UserControl { private ObservableCollection<IssueSummary> IssueSummaryList = new ObservableCollection<IssueSummary> public MainPage() { InitializeComponent(); dgIssueSummary.ItemsSource = IssueSummaryList } } However, I'd rather set the ItemsSource property in XAML, but I can't get it to work. Here's the XAML code I have: <sdk:DataGrid x:Name="dgIssueSummary" AutoGenerateColumns="False" ItemsSource="{Binding IssueSummaryList}" > <sdk:DataGrid.Columns> <sdk:DataGridTextColumn Binding="{Binding ProblemType}" Header="Problem Type"/> <sdk:DataGridTextColumn Binding="{Binding Count}" Header="Count"/> </sdk:DataGrid.Columns> </sdk:DataGrid> What do I need to do to set the ItemsSource property to be the IssueSummaryList in XAML rather than C#?

• contentEditable cursor position/style in FireFox

  I'm having trouble using contentEditable in FireFox 3. I have a problem where the cursor will appear above or only partially in the div after I click in it (until I start typing at which time it behaves correctly). Any ideas on how I can stop this from happening? HTML: <html> <head><title>Test Page</title></head> <body> <div id="editor" style="position:absolute; left:157px; top:230px; width:120px; height:30px"> <div id="input" style="width:100%; height:100%; border:1px solid black; outline:none" contentEditable="true"> </div> </div> </body> </html>

I'm currently trying this as the value of the onmouseover attribute: this.className=#{(actions.currentlySelectedActionButton == 0)?'actionButton actionButtonChosen':'actionButton'}; whereas the CSS looks like this: (the relevant parts): .actionButton { width: 100%; height: 20px; border: thin solid #000; cursor:default; } .actionButtonChosen { background-color: blue; } It's not working. Anyone spotting the error would help me greatly. Thanks!

• Problem Activating Sharepoint Timer Job

  - by Ben Robinson

  I have created a very simple sharepoint timer job. All i want it to do is iterate through a list and update each list item so that it triggers an existing workflow that works fine. In other words all i am trying to do is work around the limitation that workflows cannot be triggered on a scheduled basis. I have written a class that inherits from SPJobDefinition that does the work and i have a class that inherits from SPFeatureReceiver to install and activate it. I have created the feature using SPVisualdev that my coleagues have used in the past for other SP development. My Job class is below: public class DriverSafetyCheckTrigger : SPJobDefinition { private string pi_SiteUrl; public DriverSafetyCheckTrigger(string SiteURL, SPWebApplication WebApp):base("DriverSafetyCheckTrigger",WebApp,null, SPJobLockType.Job) { this.Title = "DriverSafetyCheckTrigger"; pi_SiteUrl = SiteURL; } public override void Execute(Guid targetInstanceId) { using (SPSite siteCollection = new SPSite(pi_SiteUrl)) { using (SPWeb site = siteCollection.RootWeb) { SPList taskList = site.Lists["Driver Safety Check"]; foreach(SPListItem item in taskList.Items) { item.Update(); } } } } } And the only thing in the feature reciever class is that i have overridden the FeatureActivated method below: public override void FeatureActivated(SPFeatureReceiverProperties Properties) { SPSite site = Properties.Feature.Parent as SPSite; // Make sure the job isn't already registered. foreach (SPJobDefinition job in site.WebApplication.JobDefinitions) { if (job.Name == "DriverSafetyCheckTrigger") job.Delete(); } // Install the job. DriverSafetyCheckTrigger oDriverSafetyCheckTrigger = new DriverSafetyCheckTrigger(site.Url, site.WebApplication); SPDailySchedule oSchedule = new SPDailySchedule(); oSchedule.BeginHour = 1; oDriverSafetyCheckTrigger.Schedule = oSchedule; oDriverSafetyCheckTrigger.Update(); } The problem i have is that when i try to activate the feature it throws a NullReferenceException on the line oDriverSafetyCheckTrigger.Update(). I am not sure what is null in this case, the example i have followed for this is this tutorial. I am not sure what I am doing wrong.

• WCF Paged Results & Data Export

  - by Ben

  I've walked into a project that is using a WCF service for the data tier. Currently, when data is needed for a grid, all rows are returned and the results are bound to a grid and the dataset is stuffed into a session variable for paging/sorting/rebinding. We've already hit a max message size problem, so I'm thinking it's time to convert from fetch and cache to fetch only the current page. Face value this seems easy enough, but there's a small catch. The user is allowed to export the entire result set at any point. This means that for grid viewing purposes fetching the current page is fine, but when they want to do an export, I still need to make a call for all data. This puts me back into the max message size issue. What is the recommended approach for this type of setup? We are currently using the wsHttpBinding... Thanks for any assistance.
