First of all I want to apologize for the English.
I'am develop windows 8.1 store app. On C++/CX language. My solution contains several projects. One of projects has the 'Windows Runtime Component' type, and perform geocoding and reverse geocoding.
For a geocoding I use 'Bing Maps SDK for Windows 8.1 Store apps'(link).
Here's my algorithm:
void addressByLocation(double latitude, double longitude)
{
ResourceLoader^ loader = ref new ResourceLoader();
String^ credentials = loader->GetString("BingMapCredentials");
Location^ location = ref new Location(latitude, longitude);
ReverseGeocodeRequestOptions^ requestOptions = ref new ReverseGeocodeRequestOptions(location);
Map^ map = ref new Map();
map->Credentials = credentials;
SearchManager^ searchManager = map->SearchManager;
task<LocationDataResponse^> reverseGeocodeTask(searchManager->ReverseGeocodeAsync(requestOptions));
reverseGeocodeTask.then([=](LocationDataResponse^ response)
{
if (!response->HasError)
{
//
}
});
}
I've got the problem in this line:
Map^ map = ref new Map();
It always generates an exception with text:
"Platform::DisconnectedException ^ at memory location 0x0396DF80.
HRESULT:0x80010108 The object invoked has disconnected from its clients.
WinRT information: The object invoked has disconnected from its clients."
But I noticed something weird. If add project to the solution which contains UI(xaml), my code in this project works perfectly fine, without any exceptions.
Can somebody specify an error to me? Or give the explanation for this strange behavior.
There is probably other methods to perform geocoding for windows 8.1 store apps, which I don't know yet.
Thanks.

I'm trying to launch an image using WinRT API WIndows::System::Launcher::LaunchFileAsync().
Code snippet is as follows:
RoInitialize(RO_INIT_MULTITHREADED);
String^ imagePath = ref new String(L"C:\\Users\\GoodMan\\Pictures\\wood.png");
auto file = Storage::StorageFile::GetFileFromPathAsync(imagePath);
Windows::System::Launcher::LaunchFileAsync(file);
I'm getting this error from the LaunchFileAsync() API:
error C2665: 'Windows::System::Launcher::LaunchFileAsync' : none of
the 2 overloads could convert all the argument types
Can I please get help how to solve this. I'm very new to WinRT C++ coding .
The method GetFileFromPathAsync does not return a StorageFile, but it returns IAsyncOperation<StorageFile>^. What you have to do is convert the latter to the former, as follows:
using namespace concurrency;
String^ imagePath = ref new String(L"C:\\Users\\GoodMan\\Pictures\\wood.png");
auto task = create_task(Windows::Storage::StorageFile::GetFileFromPathAsync(imagePath));
task.then([this](Windows::Storage::StorageFile^ file)
{
Windows::System::Launcher::LaunchFileAsync(file);
});
Generally all Windows Store app framework methods that end in Async will return either an IAsyncOperation, or a task. These methods are what are known as asynchronous methods, and require some special handling. See this article for more info: Asynchronous programming in C++ .
So now everything is great, correct? Well, not quite. There is another issue with your code. It is that when you run the code above, you will get an access-denied error. The reason is that Windows Store Apps are sandboxed, and you cannot generally access just any file on the filesystem.
You are in luck, though, because you are trying to access a file in your Pictures folder. The Pictures folder is a special folder that Windows Store apps have access to. You can get at it using the KnownFolders class:
using namespace concurrency;
Windows::Storage::StorageFolder^ pictures =
Windows::Storage::KnownFolders::PicturesLibrary;
auto task = create_task(pictures->GetFileAsync("wood.png"));
task.then([this](Windows::Storage::StorageFile^ file)
{
Windows::System::Launcher::LaunchFileAsync(file);
});
Note that in order to access the Pictures folder your application has to declare it in the project manifest. To do so, double click on the Package.appmanifest file in the project "tree" in Visual Studio, and select the Capabilities tab. Then under Capabilities, check Pictures Library.
I am using Sitecore Glass Mapper for a new project I'm setting up.
We are using Sitecore 7.2, latest version of Team Development for Sitecore (TDS) code generation and the latest version of glass.
The code I am trying to execute:
var b = new SitecoreContext();
var c = b.GetCurrentItem<T01_Homepage>();
b is not null. c is null.
var d = b.GetItem<T01_Homepage>("path")
d is null.
I added my assembly in GlassMapperScCustom:
public static IConfigurationLoader[] GlassLoaders(){
var attributes = new AttributeConfigurationLoader(new[] { "Company.Framework.Websites.Corporate", "Company.Framework.Core", "Company.Framework.Common" });
return new IConfigurationLoader[] { attributes };
}
When I look into b.GlassContext.TypeConfigurations all my models are there.
I figured it could be a language issue because the site is in dutch and maybe the wrong language would be resolved incorrectly. This was also not the case.
I disabled WebActivator and added the GlassMapperSc.Start() in my Global.asax Application_Start method.
We are also using Autofac as DI framework. But without it, it still isn't working as you can see above. Also when I create my own custom models without TDS code generation the result of GetCurrentItem<T> is null.
Does anyone have an idea how I can fix this?
Did you check your Sites.config and the default language for this website? There could be a difference between the language which is defined in your Sitecore languages folder and your configuration.
I had a similar problem with one of my projects where I changed the Sitecore.Context.Language to "nl" instead of "nl-NL". The glass mapper will return null, but Sitecore.Context.Database.GetItem will return an object in this case.
Most of the times it is a language issue. The mapper returns a null object when you do not have versions in the current or given language.
What can be confusing is that Sitecore.Context.Database.GetItem returns an object, even if it does not have a version in the current language. Be sure to check that item.Versions has any.
Some things you may try (this didn't fit in the comments field)
1) Confirm that the related fields in the Sitecore Item object contain values (so Sitecore.Context.Item for your "c" var and Sitecore.Context.Database.GetItem("path") for your "d" var)
2) Try to encapsulate the GetItem/GetCurrentItem call in a VersionCountDisabler, like this:
T01_Homepage model = null;
using (new VersionCountDisabler())
{
var context = new SitecoreContext();
model = context.GetItem<T01_Homepage>("path");
}
// Do you have data in model now?
3) Try to encapsulate the same call with a SecurityDisabler. Just to confirm it's not a security issue.
4) If you still don't know what it is, please update your question with some (simplified) code for your model.
I am trying to use the Microsoft web browser control on a form, however if you navigate to a site that takes a long time to load; the whole form UI locks up until everything is loaded. To combat this I am trying to run the web browser control seperate to everything else. I have created a small sample app using this tutorial: http://msdn.microsoft.com/en-us/library/ms171728.aspx
I have an error on the below function:
void SetNavigate(String* text)
{
if(this->axWebBrowser1->InvokeRequired)
{
SetNavigateDelegate* d = __gc new SetNavigateDelegate(this, &Form1::SetNavigate);
this->Invoke(d, __gc new Object[] { text });
}
else
{
this->axWebBrowser1->Navigate(text);
}
}
The line specifically is:
this->Invoke(d, __gc new Object[] { text });
error C2958: the left parenthesis '(' found at '\testbrowser\form1.h(56)' was not matched correctly
I had to sub delegate for __delegate, __gc new for gcnew and ^ for * so I am guessing this is another 2003 .NET being behind the times problem, does any one know the correct syntax I am looking for to stop the error appearing?
In 2003, I don't think you could use the {} array initializers inline yet. Try assigning the __gc new Object[] { text } to a named variable.
... and do anything you can to get away from writing managed c++ in vs2003. It's completely awful, and C++/CLI introduced in 2005 is a big improvement.
I'm looking for a simple C++ WebService Client Library that can be easily linked into my application.
Preferably this library:
can be used to access any SOAP WebService (so I can pass the URL, the WebService name, the WebService method and all the arguments as arguments to a function call)
can be linked statically in a C++ application (so no DLL's)
is freeware or available at a low cost
can be used royalty-free in my application
can query the Web service for its WSDL and return me the available method names, arguments of the methods and their data types
Before anyone of you answers .NET: been there, tried it. My major objections against .NET are:
you can generate the proxy but it's impossible to change the WebService name in the generated proxy code afterwards, since .NET uses reflection to check the WebService name (see Dynamically call SOAP service from own scripting language for my question regarding that problem)
generating the proxy class on the fly doesn't always seem to work correctly
I already used Google to look up this information, but I couldn't find one.
Thanks
EDIT:
To clarify this further, I really want something where I can write code like this (or something in this style):
SoapClient mySoapClient;
mySoapClient.setURL("http://someserver/somewebservice");
mySoapClient.setMethod("DoSomething");
mySoapClient.setParameter(1,"Hello");
mySoapClient.setParameter(2,12345);
mySoapClient.sendRequest();
string result;
mySoapClient.getResult(result);
No dynamic code generation.
Have you looked at gSOAP? I think it will be suitable for your needs.
http://gsoap2.sourceforge.net/
I found a solution using on-the-fly-generated assemblies (which I couldn't get working the previous time). Starting point is http://refact.blogspot.com/2007_05_01_archive.html.
E.g. This is the code to use the PeriodicTable web service:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net;
using System.Web;
using System.Web.Services;
using System.Web.Services.Description;
using System.CodeDom;
using System.CodeDom.Compiler;
using System.Xml.Serialization;
using System.IO;
using System.Reflection;
namespace GenericSoapClient
{
class Program
{
static void method1()
{
Uri uri = new Uri("http://www.webservicex.net/periodictable.asmx?WSDL");
WebRequest webRequest = WebRequest.Create(uri);
System.IO.Stream requestStream = webRequest.GetResponse().GetResponseStream();
// Get a WSDL
ServiceDescription sd = ServiceDescription.Read(requestStream);
string sdName = sd.Services[0].Name;
// Initialize a service description servImport
ServiceDescriptionImporter servImport = new ServiceDescriptionImporter();
servImport.AddServiceDescription(sd, String.Empty, String.Empty);
servImport.ProtocolName = "Soap";
servImport.CodeGenerationOptions = CodeGenerationOptions.GenerateProperties;
CodeNamespace nameSpace = new CodeNamespace();
CodeCompileUnit codeCompileUnit = new CodeCompileUnit();
codeCompileUnit.Namespaces.Add(nameSpace);
// Set Warnings
ServiceDescriptionImportWarnings warnings = servImport.Import(nameSpace, codeCompileUnit);
if (warnings == 0)
{
StringWriter stringWriter =
new StringWriter(System.Globalization.CultureInfo.CurrentCulture);
Microsoft.CSharp.CSharpCodeProvider prov =
new Microsoft.CSharp.CSharpCodeProvider();
prov.GenerateCodeFromNamespace(nameSpace,
stringWriter,
new CodeGeneratorOptions());
string[] assemblyReferences =
new string[2] { "System.Web.Services.dll", "System.Xml.dll" };
CompilerParameters param = new CompilerParameters(assemblyReferences);
param.GenerateExecutable = false;
param.GenerateInMemory = true;
param.TreatWarningsAsErrors = false;
param.WarningLevel = 4;
CompilerResults results = new CompilerResults(new TempFileCollection());
results = prov.CompileAssemblyFromDom(param, codeCompileUnit);
Assembly assembly = results.CompiledAssembly;
Type service = assembly.GetType(sdName);
//MethodInfo[] methodInfo = service.GetMethods();
List<string> methods = new List<string>();
// only find methods of this object type (the one we generated)
// we don't want inherited members (this type inherited from SoapHttpClientProtocol)
foreach (MethodInfo minfo in service.GetMethods(BindingFlags.Instance | BindingFlags.Public | BindingFlags.DeclaredOnly))
{
methods.Add(minfo.Name);
Console.WriteLine (minfo.Name + " returns " + minfo.ReturnType.ToString());
ParameterInfo[] parameters = minfo.GetParameters();
foreach (ParameterInfo pinfo in parameters)
{
Console.WriteLine(" " + pinfo.Name + " " + pinfo.ParameterType.ToString());
}
}
// Create instance of created web service client proxy
object obj = assembly.CreateInstance(sdName);
Type type = obj.GetType();
object[] args0 = new object[] { };
string result0 = (string)type.InvokeMember(methods[0], BindingFlags.InvokeMethod, null, obj, args0);
Console.WriteLine(result0);
object[] args1 = new object[] { "Oxygen" };
string result1 = (string)type.InvokeMember(methods[1], BindingFlags.InvokeMethod, null, obj, args1);
Console.WriteLine(result1);
}
}
}
}
In this code I explicitly use methods[0] and methods[1] but in reality you would check the method names of course. In this example I get the names of all elements in the periodic table, then get the atomic weight of oxygen.
This example does not yet contain logic to support a proxy. I still need to add this, but for the moment, it solves my biggest problem, namely, having a generic SOAP client.
EDIT:
I know this code is C# and I was originally asking for a C++ solution, but this code proves that it can work in a .NET environment (which I can still use in limited parts of my application), and I will probably rewrite this code into C++/.NET, which solves my problem.
Axis2C : http://axis.apache.org/axis2/c/core/index.html
Axis2C ticks most of the above , please check for static linking. .
EDIT: As per last few messages on the list, static linking is incomplete. The below still holds:
Perhaps I do not understand the question correctly. Any web service you call you need to specify the endpoint URL and the operation & parameters.
Are you referring to dynamically "discovering" the services & presenting the option to call them...? If so I doubt this is possible.
If you are referring to generic framework, SOAP messages are client end responsibility any way... You should not have a problem wrapping them under some of the toolkit API's. WSDL code generation is not mandatory. I have written a few services from scratch, i.e. You can set endpoint, service and craft the SOAP message, parameters, headers etc. as you feel.
Cheers!
I'm looking for a simple example code for C++\IronPython integration, i.e. embedding python code inside a C++, or better yet, Visual C++ program.
The example code should include: how to share objects between the languages, how to call functions\methods back and forth etc...
Also, an explicit setup procedure would help too. (How to include the Python runtime dll in Visual Studio etc...)
I've found a nice example for C#\IronPython here, but couldn't find C++\IronPython example code.
UPDATE - I've written a more generic example (plus a link to a zip file containing the entire VS2008 project) as entry on my blog here.
Sorry, I am so late to the game, but here is how I have integrated IronPython into a C++/cli app in Visual Studio 2008 - .net 3.5. (actually mixed mode app with C/C++)
I write add-ons for a map making applicaiton written in Assembly. The API is exposed so that C/C++ add-ons can be written. I mix C/C++ with C++/cli. Some of the elements from this example are from the API (such as XPCALL and CmdEnd() - please just ignore them)
///////////////////////////////////////////////////////////////////////

As you can see, I expose to IronPython some objects (DrawingList, DrawingElement, DrawingPath & Node). These objects are C++/cli objects that I created to expose "things" to IronPython.
When the C++/cli source->Execute(scope) line is called, the only python line
to run is the DrawingList.RequestData.
RequestData takes a delegate and a data type.
When the C++/cli code is done, it calls the delegate pointing to the
function "diamond"
In the function diamond it retrieves the requested data with the call to
DrawingList.RequestedValue() The call to DrawingList.AddElement(dp) adds the
new element to the Applications visual Database.
And lastly the call to DrawingList.EndCommand() tells the FastCAD engine to
clean up and end the running of the plugin.
import clr
def diamond(Result1, Result2, Result3):
if(Result1 == 0):
dp = DrawingPath()
dp.drawingStuff.EntityColor = 2
dp.drawingStuff.SecondEntityColor = 2
n = DrawingList.RequestedValue()
dp.Nodes.Add(Node(n.X-50,n.Y+25))
dp.Nodes.Add(Node(n.X-25,n.Y+50))
dp.Nodes.Add(Node(n.X+25,n.Y+50))
dp.Nodes.Add(Node(n.X+50,n.Y+25))
dp.Nodes.Add(Node(n.X,n.Y-40))
DrawingList.AddElement(dp)
DrawingList.EndCommand()
DrawingList.RequestData(diamond, DrawingList.RequestType.PointType)
I hope this is what you were looking for.
If you don't need .NET functionality, you could rely on embedding Python instead of IronPython. See Python's documentation on Embedding Python in Another Application for more info and an example. If you don't mind being dependent on BOOST, you could try out its Python integration library.
