• Notification Email Best Practices--From Server Setup to Programming

  - by Andrew Wagner

  All, I'm in the process now of building a SaaS tool that allows network admins to generate notification emails to the members of the end-users of our platform (among many many other things). I'm running into a bit of an "out of my expertise" wall, as I know there are a lot of variables involved with configuring an application that can: Run in a distributed way via load balancing and still-- Leverage a single mail server for sending notification emails Process unsubscribe requests Avoid any ISP blacklisting in the process. If anyone has the time and has done this before, I'd love if you could walk me through the A-Z of best practices both from a configuration perspective and an execution perspective for generating these emails (anything from necessary DNS settings to ideal SMTP setup and configuration) Currently, our application generates email via Google Apps using the PHPMailer class. While this works well, it doesn't queue messages (potential for timeout problems if any of our clients amass a very large list of end-users), and Google limits the amount of allowed generated email messages to 500/day. I know this is a lofty question, but any guidance you could provide would be smashing and a big help as we work through this hurtle in our beta development stage. Thanks!

• UpdateModel() fails after migration from MVC 1.0 to MVC 2.0

  - by Alastair Pitts

  We are in the process of migrating our ASP.NET MVC 1.0 web app to MVC 2.0 but we have run into a small snag. In our report creation wizard, it is possible leave the Title text box empty and have it be populated with a generic title (in the post action). The code that does the update on the model of the Title is: if (TryUpdateModel(reportToEdit, new[] { "Title" })) { //all ok here try to create (custom validation and attach to graph to follow) //if title is empty get config subject if (reportToEdit.Title.Trim().Length <= 0) reportToEdit.Title = reportConfiguration.Subject; if (!_service.CreateReport(1, reportToEdit, SelectedUser.ID, reportConfigID, reportCategoryID, reportTypeID, deviceUnitID)) return RedirectToAction("Index"); } In MVC 1.0, this works correctly,the reportToEdit has an empty title if the textbox is empty, which is then populated with the Subject property. In MVC 2.0 this fails/returns false. If I add the line above: UpdateModel(reportToEdit, new[] { "Title" }); it throws System.InvalidOperationException was unhandled by user code Message="The model of type 'Footprint.Web.Models.Reports' could not be updated." Source="System.Web.Mvc" StackTrace: at System.Web.Mvc.Controller.UpdateModel[TModel](TModel model, String prefix, String[] includeProperties, String[] excludeProperties, IValueProvider valueProvider) at System.Web.Mvc.Controller.UpdateModel[TModel](TModel model, String[] includeProperties) at Footprint.Web.Controllers.ReportsController.Step1(FormCollection form) in C:\TFS Workspace\ExtBusiness_Footprint\Branches\apitts_uioverhaul\Footprint\Footprint.Web\Controllers\ReportsController.cs:line 398 at lambda_method(ExecutionScope , ControllerBase , Object[] ) at System.Web.Mvc.ActionMethodDispatcher.Execute(ControllerBase controller, Object[] parameters) at System.Web.Mvc.ReflectedActionDescriptor.Execute(ControllerContext controllerContext, IDictionary`2 parameters) at System.Web.Mvc.ControllerActionInvoker.InvokeActionMethod(ControllerContext controllerContext, ActionDescriptor actionDescriptor, IDictionary`2 parameters) at System.Web.Mvc.ControllerActionInvoker.<>c__DisplayClassd.<InvokeActionMethodWithFilters>b__a() at System.Web.Mvc.ControllerActionInvoker.InvokeActionMethodFilter(IActionFilter filter, ActionExecutingContext preContext, Func`1 continuation) InnerException: Reading the MVC2 Release notes I see this breaking change: Every property for model objects that use IDataErrorInfo to perform validation is validated, regardless of whether a new value was set. In ASP.NET MVC 1.0, only properties that had new values set would be validated. In ASP.NET MVC 2, the Error property of IDataErrorInfo is called only if all the property validators were successful. but I'm confused how this is affecting me. I'm using the entity framework generated classes. Can anyone pinpoint why this is failing?

• WPF TreeViewItem Context Menu Unhighlights Item

  - by Snea

  I have been having problems with this for some time now, and have come up with some less-than-desirable solutions. The problem is that when a TreeViewItem's context menu is opened, the TreeViewItem is greyed out. Is it possible for a TreeViewItem to stay highlighted while its ContextMenu is open? The problem with the TreeViewItem greying out, is that it gives no relation to the context menu and the TreeViewItem, and it looks ugly. Generally, the code I use for setting a context menu is this. Sometimes the context menu will be generated by the code with a PreviewRightMouseButtonDown EventSetter, but it doesn't make a difference. <TreeView> <TreeView.Resources> <Style TargetType="{x:Type TreeViewItem}"> <Setter Property="ContextMenu"> <Setter.Value> <ContextMenu> <MenuItem Header="Menu Item 1" /> <MenuItem Header="Menu Item 2" /> </ContextMenu> </Setter.Value> </Setter> </Style> </TreeView.Resources> <TreeViewItem Header="Item 1"> <TreeViewItem Header="Sub-Item 1"/> </TreeViewItem> <TreeViewItem Header="Item 2"></TreeViewItem> </TreeView> So far the only solution I have found is to override the "grey" unfocused color with the focused color, but then the TreeView never seems unfocused, such as when another control is clicked on. I have had problems with ListViews as well.

• Entity Framework 4.0 Databinding with sorting not working

  - by Mike Gates

  I want to do something that I thought would be very simple. I want to bind a generated Entity Framework EntityCollection to a WPF DataGrid. I also want this grid to be sortable. I have tried all kinds of things to make this happen, including using a CollectionViewSource. However, nothing seems to work. Using a normal CollectionViewSource around the EntityCollection gives me: 'System.Windows.Data.BindingListCollectionView' view does not support sorting. Ok...strange. I would have thought this would work. Next on the CollectionViewSource, I try setting: CollectionViewType="ListCollectionView" Great, sorting now works. But wait, I can't add or remove entities using the grid now, presumably because ListCollectionView doesn't support this with an entity framework context. So, I guess I need to capture events coming out of the datagrid in order to add or remove entities manually from my context. Now I can't find an event to capture to detect an add...! Why is this so hard? This should be the standard "demo" case that Microsoft should have designed around. Any ideas?

• Jaxb2Marshaller and primitive types

  - by Thomas Einwaller

  Is it possible to create a web service operation using primitive or basic Java types when using the Jaxb2Marschaller in spring-ws? For example a method looking like this: @Override @PayloadRoot(localPart = "AddTaskRequest", namespace = "http://example.com/examplews/") public long addTask(final Task task) throws AddTaskFault { // do something return 0; } I am using the maven jaxws plugin to generate the interface and model classes from my WSDL. When I try to call the webservice I get the following error: java.lang.IllegalStateException: No adapter for endpoint [...]: Does your endpoint implement a supported interface like MessageHandler or PayloadEndpoint I found out that if I change the method to that: @Override @PayloadRoot(localPart = "AddTaskRequest", namespace = "http://example.com/examplews/") public JAXBElement<Long> addTask(final JAXBElement<Task> task) throws AddTaskFault { final ObjectFactory objectFactory = new ObjectFactory(); return objectFactory.createAddTaskResponse(0L); } I am able to call it - but this signature is not compatible with the interface generated by the maven jaxws plugin. What can I do to configure either spring-ws to be able to use the first kind of implementation or to tell maven jaxws plugin to generate the second variant of the interface? UPDATE: My relevant spring-ws config entries look like that: <bean id="marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller"> <property name="contextPath" value="com.example.examplews" /> </bean> <bean class="org.springframework.ws.server.endpoint.adapter.GenericMarshallingMethodEndpointAdapter"> <constructor-arg ref="marshaller" /> </bean> <bean class="org.springframework.ws.server.endpoint.mapping.PayloadRootAnnotationMethodEndpointMapping"> <property name="order" value="1" /> </bean>

• SQLiteQueryBuilder.buildQuery not using selectArgs?

  - by user297468

  Alright, I'm trying to query a sqlite database. I was trying to be good and use the query method of SQLiteDatabase and pass in the values in the selectArgs parameter to ensure everything got properly escaped, but it wouldn't work. I never got any rows returned (no errors, either). I started getting curious about the SQL that this generated so I did some more poking around and found SQLiteQueryBuilder (and apparently Stack Overflow doesn't handle links with parentheses in them well, so I can't link to the anchor for the buildQuery method), which I assume uses the same logic to generate the SQL statement. I did this: SQLiteQueryBuilder builder = new SQLiteQueryBuilder(); builder.setTables(BarcodeDb.Barcodes.TABLE_NAME); String sql = builder.buildQuery(new String[] { BarcodeDb.Barcodes.ID, BarcodeDb.Barcodes.TIMESTAMP, BarcodeDb.Barcodes.TYPE, BarcodeDb.Barcodes.VALUE }, "? = '?' AND ? = '?'", new String[] { BarcodeDb.Barcodes.VALUE, barcode.getValue(), BarcodeDb.Barcodes.TYPE, barcode.getType()}, null, null, null, null); Log.d(tag, "Query is: " + sql); The SQL that gets logged at this point is: SELECT _id, timestamp, type, value FROM barcodes WHERE (? = '?' AND ? = '?') However, here's what the documentation for SQLiteQueryBuilder.buildQuery says about the selectAgs parameter: You may include ?s in selection, which will be replaced by the values from selectionArgs, in order that they appear in the selection. ...but it isn't working. Any ideas?

• Hidden Field losing its Value on postback

  - by Ratan

  I have a ascx page where I am using a hidden field to store the value of a the drop down box as it is generated using a google address finder. My problem is that when I try to store the value directly in the hidden field : hfDdlVerifyID.Value = ddlVerifySS.SelectedValue; in the event of a button click, the value is stored but on postback is lost again. Whereas, if i try to use Scriptmanager to do it, nothing is stored. getBuild.AppendLine("$get('" + hfDdlVerifyID.ClientID + "').value = $get('" + ddlVerifySS.ClientID + ").value;"); ScriptManager.RegisterClientScriptBlock(this.Page, this.GetType(), "storeHidden", getBuild.ToString(), true); // Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "storeHidden", getBuild.ToString(), true); string test = hfDdlVerifyID.Value.ToString(); The ascx page is : <asp:UpdatePanel ID = ddlUpdate runat="server"> <ContentTemplate> <asp:Panel ID="pVerify" runat="server"> <br /> <fieldset> <legend> <asp:Literal ID="lVerify" runat="server" /> </legend> <asp:CheckBox ID ="cbVerify" runat ="server" Text ="Use the value from the following list, (Uncheck to accept address as it is)."

• How to control the download url for dotNetFx35setup.exe without using the Visual Studio bootstrapper

  - by tronda

  Previously I've used to Visual Studio 2008 setup.bin to generate a bootstrapper. I had some issues with it which were difficult to resolve and turned to dotNetInstaller. One great thing with the VS 2008 generated bootstrapper, was that I was able to control the download location for the .NET framework. By using the MSBuild task I could specify the componentsLocation: <GenerateBootstrapper ApplicationFile="$(TargetFileName)" ApplicationName="MyApp" ApplicationUrl="http://$(InstallerHost)$(DownloadUrl)" BootstrapperItems="@(BootstrapperFile)" CopyComponents="True" ComponentsLocation="Relative" OutputPath="$(OutputPath)" Path="C:\Program Files\Microsoft SDKs\Windows\v6.0A\Bootstrapper\" /> Here I'm able to use the ComponentsLocation="Relative" and the bootstrapper would download from our own web server - which is what I want. When I no longer have the VS 2008 bootstrapper, I would like to have the same feature. The new boostrapper downloads the dotNetFx35setup.exe from a defined server, but the problem is that this ".NET bootstrapper" connects to Microsoft's servers for downloading the needed packages. Trying to run the following command: dotNetFx35setup.exe /? did not show any options to control the download location. The web server will contain the package structure which the Windows SDK (v6.0A) has within the Bootstrapper\Packages directory. The structure looks like this: Packages DotNetFX DotNetFX30 DotNetFX35 DotNetFx35Client DotNetFx35SP1 ..... When I state a dependency to the .NET Framework 3.5, the DotNetFX35 directory structure gets copied into the bin/Debug directory. I've copied this directory onto the web server and it looks like this: DotNetFX35 dotNetFX20 dotNetFX30 dotNetFX35 x64 netfx35_x64.exe x86 netfx35_x86.exe dotNetMSP dotNetFx35setup.exe The other directories contains mainly MSI, MSP and MSU files. So any pointers on how to control downloading of the .NET framework. Shouldn't I use the dotNetFx35setup.exe file? If not - which should I use?

• What do these MS DTC Exceptions mean?

  - by David B

  I wrote a program to demonstrate the behavior of DTC timeouts with multiple threads. I'm getting several exceptions, seemingly at random. Are all of these simple Timeouts, or are some of them indicative of deeper problems (connection pool interactions, etc)? The Microsoft Distributed Transaction Coordinator (MS DTC) has cancelled the distributed transaction. Distributed transaction completed. Either enlist this session in a new transaction or the NULL transaction. The transaction associated with the current connection has completed but has not been disposed. The transaction must be disposed before the connection can be used to execute SQL statements. The operation is not valid for the state of the transaction. ExecuteReader requires an open and available Connection. The connection's current state is closed. Here's the data part of the code: using (DemoDataDataContext dc1 = new DemoDataDataContext(Conn1)) using (DemoDataDataContext dc2 = new DemoDataDataContext(Conn2)) { WriteMany(dc1, 100); //generate 100 records for insert WriteMany(dc2, 100000); //generate 100,000 records for insert Console.WriteLine("{0} : {1}", Name, " generated records for insert."); using (TransactionScope ts = new TransactionScope()) { dc1.SubmitChanges(); dc2.SubmitChanges(); ts.Complete(); } }

• Error using Dynamic Data Filtering: missing datasource

  - by sebastiaan

  I am trying to use the ASP.NET Dynamic Data Filtering project, but I'm running into a problem during the configuration. I'm following the instructions on the author's blog, and everything works like described. Then it tells me to change the datasource using the designer view. I am told to select the "GridDataSource" in the "Configure data source" wizard. This option is not there though. I get all of the classes in my project, including the DataContext that was generated by Linq. When I choose "Show only DataContext objects", the dropdown ("Choose your context object:") is completely empty. When I turn of the checkbox and choose my DataContext class, I get asked which table I want and all that. But, as the whole purpose of a Dynamic Data site is NOT to use one single table, that's not much help. So I've looked at the instructions again and copied the resulting datasource from the example: <asp:DynamicLinqDataSource ID="GridDataSource" runat="server" EnableDelete="True" EnableUpdate="True"></asp:DynamicLinqDataSource> Which is exactly what I had, without the "WhereParameters" nodes in there. Now, when I run the list page however, I get an exception about a missing datasource from the filtering component. Of course when I remove the DynamicFilterRepeater, it works again. This is the meat of the exception: [InvalidOperationException: Missing DataSource] Catalyst.Web.DynamicData.DynamicFilterRepeater.GetTable() in D:\Catalyst\Projects\DynamicData\Project\Trunk\DynamicData\DynamicData\DynamicFilterRepeater.cs:74 Catalyst.Web.DynamicData.DynamicFilterRepeater.GetFilters() in D:\Catalyst\Projects\DynamicData\Project\Trunk\DynamicData\DynamicData\DynamicFilterRepeater.cs:81 Catalyst.Web.DynamicData.DynamicFilterRepeater.OnInit(EventArgs e) in D:\Catalyst\Projects\DynamicData\Project\Trunk\DynamicData\DynamicData\DynamicFilterRepeater.cs:106 How do I make the DynamicFilterRepeater recognize my datasource? I'm using VS2010 Pro, on a Win7 machine.

• Connecting git to github on windows 7 without bash

  - by George Mauer

  I'm setting up git on my new Windows 7 machine and I'm hitting a roadblock when it comes to getting github to acknowledge my ssh key. I am doing things a little different from the standard script in that I would rather not use cygwin and prefer to use my powershell prompt. The following is what I did: I installed msysgit (portable). I went to C:\program files\git\bin and used ssh-keygen to generate a public/private ssh keypair which I put in c:\Temp I then created a directory named .ssh\ in c:\Users\myusername\ (on windows 7) I moved both the files generated by the ssh-keygen (id_rsa and id_rsa.pub) into the .ssh directory I went to my account on github, created a new public key, copy-pasted the contents of id_rsa.pub into it and saved I now go to my powershell prompt, set-alias git 'C:\program files\git\bin\git.exe' I try to now do a clone [email protected]:togakangaroo/ps-profile.git which rejects my authentication: Permission denied (publickey). fatal: The remote end hung up unexpectedly Past experience says that this means git is not recognizing my key. What steps am I missing? I have a feeling that I need to somehow configure git so that it knows where my ssh keys are (though it would seem it should look there automatically) but I don't know how to do that. Another possible clue is that when I try to run git config --global user.name "George Mauer" I get an error fatal: $HOME not set I did however set up a HOME environment user variable with the value %HOMEDRIVE%%HOMEPATH%

• Crazy idea: Connect .NET and SAP with SAP JCo using IKVM.NET

  - by Kottan

  Because the SAP Connector for .NET is no longer maintained by SAP, I am now looking for an alternative to connect the Microsoft world with the SAP world. I know there a third party products like ERPConnect, but I want to do this with tools from SAP. Therefore there arised the crazy idea to use the SAP Java Connector in combination with the tool IKVM.NET (www.ikvm.net/devguide/net2java.html). IKVM.NET provides The IKVMC tool, which converts Java bytecode to .NET dll's and exe's. "No sooner said than done!" I converted the SAP JCo to .NET dlls and created a new Visual Studio solution. I put all the JCO files into a subdirectory of my solution. I set 2 references to the generated IKVM.OpenJDK.Core.dll and sapjco.dll. Great, all JCO classes where now available as .NET classes. Full of optimism I wrote some little code to connect to a SAP system. JCO.Client client = null; client = JCO.createClient(...) The compiliation of my testcode had no errors. "Wonderful !" I thought. Then I started my tetstapplication. Unfortunately I got an exception calling JCO.createClient: Could not load middleware layer 'com.sap.mw.jco.rfc.MiddlewareRFC'\r\nno sapjcorfc in java.library.path I have 2 questions on this topic. 1) Do you think my idea using SAP Java Connector to connect .NET with SAP is a good idea or is it nonsens ? Perhaps someone had already the same idea ;-) 2) How can the above exception be solved ?

• Add inset box-shadow on Google Maps element

  - by linkyndy

  I am willing to add some inset box-shadow to a tag that is containing a Google Maps element. However, it seems nothing happens, probably because Google loads some other div's in the original element, hence covering the generated box-shadow. How can I achieve this effect? Here's the code I have: <section id="map-container"> <figure id="map"></figure> </section> #map-container { position: relative; float: right; width: 700px; background-color: #F9FAFC; border-top-right-radius: 5px; border-bottom-right-radius: 5px; } #map { position: relative; height: 400px; border-top-right-radius: 5px; border-bottom-right-radius: 5px; box-shadow: 0 1px 0 0 #F6F7FB inset, 0 -1px 0 0 #E0E5E1 inset, 0 -2px 0 0 #EBEBED inset, 0 -3px 0 0 #F4F4F6 inset; } Thank you!

• Using FluentValidation with Castle Windsor and Entity Framework 4.0 (POCO) in MVC2

  - by Brian McCord

  This isn't a very simple question, but hopefully someone has run across it. I am trying to get the following things working together: MVC2 FluentValidation Entity Framework 4.0 (POCO) Castle Windsor I've pretty much gotten everything working. I have Castle Windsor implemented and working with the Controllers being served up by the WindsorControllerFactory that is part of MVCContrib. I also have Castle serving up the FluentValidation validators as is described by this article: http://www.jeremyskinner.co.uk/2010/02/22/using-fluentvalidation-with-an-ioc-container/ My problem comes in when I try to use Html.EditorForModel or EditorFor on a view. When I try to do that I get this error message: No component for supporting the service FluentValidation.IValidator`1[[System.Data.Entity.DynamicProxies.State_71C51A42554BA6C3CF05105DA05435AD209602C217FC4C34CA52ACEA2B06B99B, EntityFrameworkDynamicProxies-BrindleyInsurance.BusinessObjects, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]] was found This is due to using the POCO generation on Entity Framework 4.0. At runtime, the generated classes get wrapped with a Dynamic Proxy so tracking and lazy loading can happen. Apparently, when using EditorForModel or EditorFor, it tries to ask Windsor to create a validator for the dynamic proxy type instead of the underlying real type. Does anyone know what I can do to solve this issue?

• Using JavaScript/jQuery to return a list of CSS selectors based on highlighted text

  - by Bungle

  I've been given some project requirements that involve (ideally) returning a list of CSS selectors based on highlighted text. In other words, a user could do something like this on a page: Click a button to indicate that their next text selection should be recorded. Highlight some text on the page. See a generated list of CSS selectors that correspond to all the elements that contain the highlighted text. Firstly, does this seem like a feasible goal? jQuery makes it easy to use a selector to access a particular element, but I'm not sure if the reverse holds true. If an element lacks an id attribute, I also don't know how you'd return an "optimized" selector - i.e., one that identifies an element uniquely. Maybe crawl up the DOM until you find an ID, then stem the selector from there? Secondly, from a high-level perspective, any ideas on how to go about this? Any tips or tricks that could speed development? I very much appreciate any help. Thanks!

• Visual Studio Templates - adding additional pre-existing projects

  - by Bob Palmer

  Hey all, I'm working on a Visual Studio template where the generated project relies on a number of references, which happen to be other projects under source control. The question is how do I set this up in my ProjectGroup template? For example, if I have an already existing project at "C:\Stuff\MyUtilityProject\Utility.csproj" with a single file (Tools.cs) that I want to add to my template, how would I go about this? Here's what my vstempalte looks like. FYI - I am having no issues with the ProjectTemplateLink or creation of the Solution folder, just in adding the pre-existing Utility.csproj to my new solution: Thanks in advance! <VSTemplate Version="2.0.0" xmlns="http://schemas.microsoft.com/developer/vstemplate/2005" Type="ProjectGroup"> <TemplateData> <Name>MySampleSolution</Name> <Description>My Test Project</Description> <ProjectType>CSharp</ProjectType> <Icon>__TemplateIcon.ico</Icon> </TemplateData> <TemplateContent> <ProjectCollection> <SolutionFolder Name="Content"> <Project File="C:\Stuff\MyUtilityProject\Utility.csproj"> <ProjectItem>Tools.cs</ProjectItem> </Project> </SolutionFolder> <ProjectTemplateLink ProjectName="MyWorkingTemplate"> MyWorkingTemplate\MyTemplate.vstemplate </ProjectTemplateLink> </ProjectCollection> </TemplateContent> </VSTemplate>

• How to parse nagios status.dat file?

  - by daniels

  I'd like to parse status.dat file for nagios3 and output as xml with a python script. The xml part is the easy one but how do I go about parsing the file? Use multi line regex? It's possible the file will be large as many hosts and services are monitored, will loading the whole file in memory be wise?

• mysql query to dynamically convert row data to columns

  - by Anirudh Goel

  I am working on a pivot table query. The schema is as follows Sno, Name, District The same name may appear in many districts eg take the sample data for example 1 Mike CA 2 Mike CA 3 Proctor JB 4 Luke MN 5 Luke MN 6 Mike CA 7 Mike LP 8 Proctor MN 9 Proctor JB 10 Proctor MN 11 Luke MN As you see i have a set of 4 distinct districts (CA, JB, MN, LP). Now i wanted to get the pivot table generated for it by mapping the name against districts Name CA JB MN LP Mike 3 0 0 1 Proctor 0 2 2 0 Luke 0 0 3 0 i wrote the following query for this select name,sum(if(District="CA",1,0)) as "CA",sum(if(District="JB",1,0)) as "JB",sum(if(District="MN",1,0)) as "MN",sum(if(District="LP",1,0)) as "LP" from district_details group by name However there is a possibility that the districts may increase, in that case i will have to manually edit the query again and add the new district to it. I want to know if there is a query which can dynamically take the names of distinct districts and run the above query. I know i can do it with a procedure and generating the script on the fly, is there any other method too? I ask so because the output of the query "select distinct(districts) from district_details" will return me a single column having district name on each row, which i will like to be transposed to the column.

• C++ compiler errors in xamltypeinfo.g.cpp

  - by Richard Banks

  I must be missing something obvious but I'm not sure what. I've created a blank C++ metro app and I've just added a model that I will bind to in my UI however I'm getting a range of compiler warnings related to xamltypeinfo.g.cpp and I'm not sure what I've missed. My header file looks like this: #pragma once #include "pch.h" #include "MyColor.h" using namespace Platform; namespace CppDataBinding { [Windows::UI::Xaml::Data::Bindable] public ref class MyColor sealed : Windows::UI::Xaml::Data::INotifyPropertyChanged { public: MyColor(); ~MyColor(); virtual event Windows::UI::Xaml::Data::PropertyChangedEventHandler^ PropertyChanged; property Platform::String^ RedValue { Platform::String^ get() { return _redValue; } void set(Platform::String^ value) { _redValue = value; RaisePropertyChanged("RedValue"); } } protected: void RaisePropertyChanged(Platform::String^ name); private: Platform::String^ _redValue; }; } and my cpp file looks like this: #include "pch.h" #include "MyColor.h" using namespace CppDataBinding; MyColor::MyColor() { } MyColor::~MyColor() { } void MyColor::RaisePropertyChanged(Platform::String^ name) { if (PropertyChanged != nullptr) { PropertyChanged(this, ref new Windows::UI::Xaml::Data::PropertyChangedEventArgs(name)); } } Nothing too tricky, but when I compile I get errors in xamltypeinfo.g.cpp indicating that MyColor is not defined in CppDataBinding. The relevant generated code looks like this: if (typeName == "CppDataBinding.MyColor") { userType = ref new XamlUserType(this, typeName, GetXamlTypeByName("Object")); userType->Activator = ref new XamlTypeInfo::InfoProvider::Activator( []() -> Platform::Object^ { return ref new CppDataBinding::MyColor(); }); userType->AddMemberName("RedValue", "CppDataBinding.MyColor.RedValue"); userType->SetIsBindable(); xamlType = userType; } If I remove the Bindable attribute from MyColor the code compiles. Can someone tell me what blindingly obvious thing I've missed so I can give myself a facepalm and fix the problem?

• Echo styles into the mashup of a google map and wordpress custom fields

  - by zac

  Using wordpress, I am pulling in a custom fields from specific posts to fill in the content for a google generated map. I am using this code var point = new GLatLng(48.5139,-123.150531); var marker = createMarker(point,"Lime Kiln State Park", '<?php $post_id = 182; $my_post = get_post($post_id); $title = $my_post->post_title; $snip = get_post_meta($post_id, 'mapExcerpt', true); echo $title; echo $snip; ?>') map.addOverlay(marker); I am trying to echo css style blocks but this causes a javascript error var point = new GLatLng(48.5139,-123.150531); var marker = createMarker(point,"Lime Kiln State Park", '<?php $post_id = 182; $my_post = get_post($post_id); $title = $my_post->post_title; $snip = get_post_meta($post_id, 'mapExcerpt', true); echo "<div class='theTitle'>"; echo $title; echo "</div>"; echo $snip; ?>') map.addOverlay(marker); I get the error missing ) after argument list and the output is var point = new GLatLng(48.5139,-123.150531); var marker = createMarker(point,"Lime Kiln State Park", '<div class='theTitle'>Site Title</div>Site excerpt') map.addOverlay(marker); Can someone please show me a more elegant (working) solution for this?

• Jar not found when executing class

  - by Simon

  Hi there, I'm working through the ANTLR book and there are many examples that should be easy to compile using the command line. Some information to get te problem: antlr-3.2.jar contains the ANTLR classes. I added the antlr-3.2.jar to the CLASSPATH environment variable (Windows 7) and when compiling the classes with javac everything works fine. This is what i execute to compile my program: javac Test.java ExprLexer.java ExprParser.java Test.java contains my main()-method whereas ExprLexer and ExprParser are generated by ANTLR. All three classes use classes contained in the antlr-3.2.jar. But so far so good. As I just said, compiling works fine. It's when I try to execute the Test.class that I get trouble. This is what I type: java -cp ./ Test When executing this, the interpreter tells me that he can't find the ANTLR-classes contained in the antlr-3.2.jar, altough I added an entry in the CLASSPATH variable. E:\simone\Programmierung\Language Processing Tools\ANTLR\Book Samples and Exercises\Exercise\1\output\Test.java Exception in thread "main" java.lang.NoClassDefFoundError: org/antlr/runtime/Cha rStream Caused by: java.lang.ClassNotFoundException: org.antlr.runtime.CharStream at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:248) Could not find the main class: Test. Program will exit. I'm using Windows 7 and Java 1.6_20. Can someone tell what is going on? Why will the interpreter not look in the jar-Archive I specified in the CLASSPATH? I found some kind of workaroud. I copied the antlr-3.2.jar into the directory where the Test.class is located and then executed: java -cp ./;antlr-3.2.jar Test This worked out. But I don't want to type the jar-Archive everytime I execute my test programs. Is there a possibility to tell the interpreter that he should automatically look into the archive?

• Maven WTP webapp with maven-eclipse-plugin but without m2eclipse

  - by chrsk

  I use the eclipse:eclipse goal to generate an Eclipse Project environment. The deployment works fine. The goal creates the var classpath entries for all needed dependencies. With m2eclipse there was the Maven Container which defines an export folder which was WEB-INF/lib for me. But i don't want to rely on m2eclipse so i don't want to use it anymore. the class path entries which are generated by eclipse:eclipse goal don't have such a export folder. While booting the servlet container with WTP it publishes all resources and classes except the libraries to the context. Whats missing to publish the needed libs, or isn't that possible without m2eclipse integration?
