I need to translate this code from lucene.net 2.3.2 to 3.0.3.
This code works fine in 2.3.2 but in 3.0.3 the method tokenStream.Next() does not return a token but a boolean. What I need to understand is where to read the token object when next() returns true.
Analyzer analyzer = new StandardAnalyzer();
StringReader stringReader = new StringReader("the house id red");
TokenStream tokenStream = analyzer.TokenStream("", stringReader);
Token token = tokenStream.Next();
while (token != null)
{
System.Diagnostics.Debug.Write(token.TermText());
token = tokenStream.Next();
}
The TokenStreams in Lucene 3+ can now represent a whole set of values (called attributes) for each position in the stream. So you need to modify your example to be attribute aware...
var analyzer = new StandardAnalyzer(Lucene.Net.Util.Version.LUCENE_30);
var stringReader = new StringReader("the house id red");
var tokenStream = analyzer.TokenStream(string.Empty, stringReader);
var termAtt = tokenStream.GetAttribute<ITermAttribute>();
while (tokenStream.IncrementToken())
{
Console.WriteLine(termAtt.Term);
}

On CRM 2013 on-premise, I'm trying to write a plugin that triggers when an update is made to a field on Quote. The plugin then creates a new custom entity "new_contract".
My plugin is successfully triggered when the update to that field is made. However I keep getting an error message "The given key was not present in the dictionary" when trying to create the new custom entity.
I'm using a "PostImage" in this code. I confirm that it's registered using the same name in Plugin Registration.
Here is the code
var targetEntity = context.GetParameterCollection<Entity>
(context.InputParameters, "Target");
if (targetEntity == null)
{throw new InvalidPluginExecutionException(OperationStatus.Failed,
"Target Entity cannot be null")}
var postImage = context.PostEntityImages["PostImage"];
if (postImage == null)
{throw new InvalidPluginExecutionException(OperationStatus.Failed,
"Post Image is required");}
var quote = context.GenerateCompositeEntity(targetEntity, postImage);
//throw new InvalidPluginExecutionException(OperationStatus.Failed, "Update is captured");
//Guid QuoteId = (Guid)quote.Attributes["quoteid"];
var serviceFactory = (IOrganizationServiceFactory)serviceProvider
.GetService(typeof(IOrganizationServiceFactory));
var service = serviceFactory.CreateOrganizationService(context.UserId);
var contractEntity = new Entity();
contractEntity = new Entity("new_contract");
if (quote.Attributes.Contains("portfolio"))
{
var quotePortfolio = (EntityReference)quote.Attributes["new_portfolio];
contractEntity[Schema.new_contract.PortfolioName] =
new EntityReference(quotePortfolio.LogicalName, quotePortfolio.Id);
}
if (quote.Attributes.Contains(Schema.Quote.QuoteName))
{
var quoteName = (string)quote.Attributes["name"];
contractEntity[Schema.new_contract.contractName] = quoteName;
}
var contractId = service.Create(contractEntity);
I think context does not contain "PostImage" attribute.You should check context to see whether it contains the attribute before getting the data.
Looking at this line in your post above:
var service = serviceFactory.CreateOrganizationService(context.UserId);
I am deducing that the type of your context variable is LocalPluginContext (since this contains the UserId value) which does not expose the images (as another answer states).
To access the images, you need to get to the Plugin Execution Context:
IPluginExecutionContext pluginContext = context.PluginExecutionContext;
Entity postImage = null;
if (pluginContext.PostEntityImages != null && pluginContext.PostEntityImages.Contains("PostImage))
{
postImage = pluginContext.PostEntityImages["PostImage"];
}
In the below code segment, you are checking for the attribute "portfolio" and using "new_portfolio". Can you correct that and let us know whether that worked.
if (quote.Attributes.Contains("portfolio"))
{
var quotePortfolio = (EntityReference)quote.Attributes["new_portfolio];
contractEntity[Schema.new_contract.PortfolioName] = new EntityReference(quotePortfolio.LogicalName, quotePortfolio.Id);
}
First, you don't say what line is throwing the exception. Put in the VS debugger and find the line that is throwing the exception.
I did see that you are trying to read from a dictionary here without first checking if the dictionary contains the key, that can be the source of this exception.
var postImage = context.PostEntityImages["PostImage"];
if (postImage == null)
throw new InvalidPluginExecutionException(OperationStatus.Failed,
"Post Image is required");
Try this:
if(!context.PostEntityImages.Contains("PostImage") ||
context.PostEntityImages["PostImage"] == null)
InvalidPluginExecutionException(OperationStatus.Failed, "Post Image is required");
var postImage = context.PostEntityImages["PostImage"];
Although, I don't think that a PostEntityImage Value will ever be null, if it passes the Contains test you don't really need the null check.
I'm trying to query invoices using the .NET IPP DevKit v3.
Following all the directions found on the documentation site, I can query invoices and add skip/take/order by/where/etc to the query when using ONLY default fields. But, as soon as I add non-default fields, skip/take/order by/where/etc does NOT seem to work.
Here's the error:
System.ArgumentException was unhandled
HResult=-2147024809
Message=Expression of type 'System.Collections.Generic.IEnumerable`1[<>f__AnonymousType0`3[Intuit.Ipp.Data.Invoice,Intuit.Ipp.Data.Line[],Intuit.Ipp.Data.LinkedTxn[]]]' cannot be used for parameter of type 'System.Linq.IQueryable`1[<>f__AnonymousType0`3[Intuit.Ipp.Data.Invoice,Intuit.Ipp.Data.Line[],Intuit.Ipp.Data.LinkedTxn[]]]' of method 'System.Linq.IQueryable`1[<>f__AnonymousType0`3[Intuit.Ipp.Data.Invoice,Intuit.Ipp.Data.Line[],Intuit.Ipp.Data.LinkedTxn[]]] Skip[<>f__AnonymousType0`3](System.Linq.IQueryable`1[<>f__AnonymousType0`3[Intuit.Ipp.Data.Invoice,Intuit.Ipp.Data.Line[],Intuit.Ipp.Data.LinkedTxn[]]], Int32)'

What am I missing here?
Code:
string AppToken = "your AppToken goes here";
string AppConsumerKey = "your AppConsumerKey goes here";
string AppConsumerKeySecret = "your AppConsumerKeySecret goes here";
string AccessToken = "your AccessToken goes here";
string AccessTokenSecret = "your AccessTokenSecret goes here";
string RealmCompanyId = "your RealmId goes here";
OAuthRequestValidator oauthValidator = new OAuthRequestValidator(AccessToken, AccessTokenSecret, AppConsumerKey, AppConsumerKeySecret);
ServiceContext context = new ServiceContext(AppToken, RealmCompanyId, IntuitServicesType.QBD, oauthValidator);
QueryService<Intuit.Ipp.Data.Invoice> qs = new QueryService<Intuit.Ipp.Data.Invoice>(context);
// This works...
var defaultQuery = qs.Select(c => c).Skip(0).Take(10).OrderBy(c => c.Id);
var defaultList = defaultQuery.ToList();
// This works...
var nonDefaultQuery = qs.Select(c => new { c, c.Line, c.LinkedTxn });
var nonDefaultList = nonDefaultQuery.ToList();
// This does NOT work!!
var nonDefaultQueryWithSkip = qs.Select(c => new { c, c.Line, c.LinkedTxn }).Skip(0).Take(10);
var nonDefaultListWithSkip = nonDefaultQueryWithSkip.ToList();
I tried on the API explorer-
Select *,Line.*, LinkedTxn.* FROM Invoice startPosition 1 maxResults 10 (which is your last query) and it works fine but not from .net sdk. I will double check this on the .net SDK and get back to you. Can you verify that you get the correct results on API explorer from this query?
This now works in the latest version (IppDotNetSdkForQuickBooksApiV3.2.0.0)
Here's an example:
QueryService<Intuit.Ipp.Data.Invoice> qs = new QueryService<Intuit.Ipp.Data.Invoice>(context);
string query = string.Format("SELECT *, Line.* FROM Invoice ORDERBY Id STARTPOSITION {0} MAXRESULTS {1}", startPos, pageSize);
var recs = qs.ExecuteIdsQuery(query);
foreach (Intuit.Ipp.Data.Invoice rec in recs)
{
// do stuff...
}

I have a plugin in post-operation witch need to create a folder on sharepoint via webservice, to do that, my plugin calls a webservice to execute a FechXML to get the info from the entity, but the problem is that entity still not exist, and it give me Null.
How do i force the plugin to submit/save the data to my FechXml to work?

When a plugin runs on the Post-Operation, it is still within the database transaction, and it hasn't actually been committed to the database. Any calls done with the service reference passed in as a part of the Plugin Context will be executed within the context on the database transaction and you will be able to retrieve the newly created/updated values. If you create a brand new OrganizationServiceProxy (Which I'm guessing is what you're doing), it will execute outside of the database transaction, and will not see the newly created / updated values.
As #AndyMeyers suggests in his comment (which really should be an answer IMHO), grabbing the data from the plugin context either via a pre/post image or the target is ideal since it eliminates another database call. If you're having to lookup records that may have been created by another plugin that fired earlier, you'll need to use the IOrganizationService that is included in the plugin context.
I had no option and I used this code to run webservice based on image and forget the FecthXml, as mentioned, i get all info from the Image on the post operation and send back to the WebService. Thanks, here is the code:
entity = (Entity)context.InputParameters["Target"];
concursid = (Guid)entity.Attributes["fcg_concursid"];
guid = concursid.ToString();
string npconcurs = (string)entity.Attributes["fcg_numer"];
nconcurs= npconcurs;
EntityReference nprograma = (EntityReference)entity.Attributes["fcg_unidadeorganica"];
program = nprogram.Name;
if (entity.LogicalName != "fcg_concurs")
I am trying to index into a document a field with one term that has a payload.
Since the only constructor of Field that can work for me takes a TokenStream, I decided to inherit from this class and give the most basic implementation for what I need:
public class MyTokenStream : TokenStream
{
TermAttribute termAtt;
PayloadAttribute payloadAtt;
bool moreTokens = true;
public MyTokenStream()
{
termAtt = (TermAttribute)GetAttribute(typeof(TermAttribute));
payloadAtt = (PayloadAttribute)GetAttribute(typeof(PayloadAttribute));
}
public override bool IncrementToken()
{
if (moreTokens)
{
termAtt.SetTermBuffer("my_val");
payloadAtt.SetPayload(new Payload(/*bye[] data*/));
moreTokens = false;
}
return false;
}
}
The code which was used while indexing:
IndexWriter writer = //init tndex writer...
Document d = new Document();
d.Add(new Field("field_name", new MyTokenStream()));
writer.AddDocument(d);
writer.Commit();
And the code that was used during the search:
IndexSearcher searcher = //init index searcher
Query query = new TermQuery(new Term("field_name", "my_val"));
TopDocs result = searcher.Search(query, null, 10);
I used the debugger to verify that call to IncrementToken() actually sets the TermBuffer.
My problem is that the returned TopDocs instance returns no documents, and I cant understand why... Actually I started from TermPositions (which gives me approach to the Payload...), but it also gave me no results.
Can someone explain to me what am I doing wrong?
I am currently using Lucene .NET 2.9.2
After you set the TermBuffer you need to return true from IncrementToken, you return false when you have nothing to feed the TermBuffer with anymore
I need to change the storage schema of the entities on runtime.
I've followed a wonderful post, available here:
http://blogs.microsoft.co.il/blogs/idof/archive/2008/08/22/change-entity-framework-storage-db-schema-in-runtime.aspx?CommentPosted=true#commentmessage
This works perfectly, but only for queries, not for modifications.
Any idea why?
Well, I was looking for this piece of code all around the Internet. In the end I had to do it myself. It's based on Brandon Haynes adapter, but this function is all you need to change the schema on runtime - and you don't need to replace the autogenerated context constructors.
public static EntityConnection Create(
string schema, string connString, string model)
{
XmlReader[] conceptualReader = new XmlReader[]
{
XmlReader.Create(
Assembly
.GetExecutingAssembly()
.GetManifestResourceStream(model + ".csdl")
)
};
XmlReader[] mappingReader = new XmlReader[]
{
XmlReader.Create(
Assembly
.GetExecutingAssembly()
.GetManifestResourceStream(model + ".msl")
)
};
var storageReader = XmlReader.Create(
Assembly
.GetExecutingAssembly()
.GetManifestResourceStream(model + ".ssdl")
);
XNamespace storageNS = "http://schemas.microsoft.com/ado/2009/02/edm/ssdl";
var storageXml = XElement.Load(storageReader);
foreach (var entitySet in storageXml.Descendants(storageNS + "EntitySet"))
{
var schemaAttribute = entitySet.Attributes("Schema").FirstOrDefault();
if (schemaAttribute != null)
{
schemaAttribute.SetValue(schema);
}
}
storageXml.CreateReader();
StoreItemCollection storageCollection =
new StoreItemCollection(
new XmlReader[] { storageXml.CreateReader() }
);
EdmItemCollection conceptualCollection = new EdmItemCollection(conceptualReader);
StorageMappingItemCollection mappingCollection =
new StorageMappingItemCollection(
conceptualCollection, storageCollection, mappingReader
);
var workspace = new MetadataWorkspace();
workspace.RegisterItemCollection(conceptualCollection);
workspace.RegisterItemCollection(storageCollection);
workspace.RegisterItemCollection(mappingCollection);
var connectionData = new EntityConnectionStringBuilder(connString);
var connection = DbProviderFactories
.GetFactory(connectionData.Provider)
.CreateConnection();
connection.ConnectionString = connectionData.ProviderConnectionString;
return new EntityConnection(workspace, connection);
}
The resulting EntityConnection should be passed as a parameter when instantiating the context. You can modify it, so all ssdl models are modified by this function, not only the specified one.
I've managed to resolve this issue by using a brilliant library, located in CodePlex (courtesy of Brandon Haynes), named "Entity Framework Runtime Model Adapter", available here:
http://efmodeladapter.codeplex.com/
I've tweaked it a bit, to fit our needs and without the need of replacing the designer code at all.
So, I'm good.
Thanks anyways, and especially to Brandon, amazing job!
I need import data from postgres database. It by default use schema "public". So I use Entity Framework CTP 4 "Code first". It by default use schema "dbo". To change it in runtime I use:
public class PublicSchemaContext : DbContext
{
protected override void OnModelCreating(System.Data.Entity.ModelConfiguration.ModelBuilder builder)
{
builder.Entity<series_categories>().MapSingleType().ToTable("[public].[series_categories]");
}
public DbSet<series_categories> series_categories { get; set; }
}
It work for select, insert, update and delete data. So next test in pass:
[Test]
public void AccessToPublicSchema()
{
// Select
var db = new PublicSchemaContext();
var list = db.series_categories.ToList();
Assert.Greater(list.Count, 0);
Assert.IsNotNull(list.First().series_category);
// Delete
foreach (var item in db.series_categories.Where(c => c.series_category == "Test"))
db.series_categories.Remove(item);
db.SaveChanges();
// Insert
db.series_categories.Add(new series_categories { series_category = "Test", series_metacategory_id = 1 });
db.SaveChanges();
// Update
var test = db.series_categories.Single(c => c.series_category == "Test");
test.series_category = "Test2";
db.SaveChanges();
// Delete
foreach (var item in db.series_categories.Where(c => c.series_category == "Test2"))
db.series_categories.Remove(item);
db.SaveChanges();
}
Not an answer per se but a followup on Jan Matousek's Create[EntityConnection] method showing how to use from a DbContext. Note DB is the DbContext type passed to the generic repository.
public TxRepository(bool pUseTracking, string pServer, string pDatabase, string pSchema="dbo")
{
// make our own EF database connection string using server and database names
string lConnectionString = BuildEFConnectionString(pServer, pDatabase);
// do nothing special for dbo as that is the default
if (pSchema == "dbo")
{
// supply dbcontext with our connection string
mDbContext = Activator.CreateInstance(typeof(DB), lConnectionString) as DB;
}
else // change the schema in the edmx file before we use it!
{
// Create an EntityConnection and use that to create an ObjectContext,
// then that to create a DbContext with a different default schema from that specified for the edmx file.
// This allows us to have parallel tables in the database that we can make available using either schema or synonym renames.
var lEntityConnection = CreateEntityConnection(pSchema, lConnectionString, "TxData");
// create regular ObjectContext
ObjectContext lObjectContext = new ObjectContext(lEntityConnection);
// create a DbContext from an existing ObjectContext
mDbContext = Activator.CreateInstance(typeof(DB), lObjectContext, true) as DB;
}
// finish EF setup
SetupAndOpen(pUseTracking);
}
I was able to convert the solution from Jan Matousek to work in vb.net 2013 with entity framework 6. I will also try to explain how to use the code in vb.net.
We have a JD Edwards Database which uses different Schema's for each environment (TESTDTA, CRPDTA, PRODDTA). This makes switching between environments cumbersome as you have to manually modify the .edmx file if you want to change environments.
First step is to create a partial class that allows you to pass a value to the constructor of your entities, by default it uses the values from your config file.
Partial Public Class JDE_Entities
Public Sub New(ByVal myObjectContext As ObjectContext)
MyBase.New(myObjectContext, True)
End Sub
End Class
Next create the function that will modify your store schema .ssdl file in memory.
Public Function CreateObjectContext(ByVal schema As String, ByVal connString As String, ByVal model As String) As ObjectContext
Dim myEntityConnection As EntityConnection = Nothing
Try
Dim conceptualReader As XmlReader = XmlReader.Create(Me.GetType().Assembly.GetManifestResourceStream(model + ".csdl"))
Dim mappingReader As XmlReader = XmlReader.Create(Me.GetType().Assembly.GetManifestResourceStream(model + ".msl"))
Dim storageReader As XmlReader = XmlReader.Create(Me.GetType().Assembly.GetManifestResourceStream(model + ".ssdl"))
Dim storageNS As XNamespace = "http://schemas.microsoft.com/ado/2009/11/edm/ssdl"
Dim storageXml = XDocument.Load(storageReader)
Dim conceptualXml = XDocument.Load(conceptualReader)
Dim mappingXml = XDocument.Load(mappingReader)
For Each myItem As XElement In storageXml.Descendants(storageNS + "EntitySet")
Dim schemaAttribute = myItem.Attributes("Schema").FirstOrDefault
If schemaAttribute IsNot Nothing Then
schemaAttribute.SetValue(schema)
End If
Next
storageXml.Save("storage.ssdl")
conceptualXml.Save("storage.csdl")
mappingXml.Save("storage.msl")
Dim storageCollection As StoreItemCollection = New StoreItemCollection("storage.ssdl")
Dim conceptualCollection As EdmItemCollection = New EdmItemCollection("storage.csdl")
Dim mappingCollection As StorageMappingItemCollection = New StorageMappingItemCollection(conceptualCollection, storageCollection, "storage.msl")
Dim workspace = New MetadataWorkspace()
workspace.RegisterItemCollection(conceptualCollection)
workspace.RegisterItemCollection(storageCollection)
workspace.RegisterItemCollection(mappingCollection)
Dim connectionData = New EntityConnectionStringBuilder(connString)
Dim connection = DbProviderFactories.GetFactory(connectionData.Provider).CreateConnection()
connection.ConnectionString = connectionData.ProviderConnectionString
myEntityConnection = New EntityConnection(workspace, connection)
Return New ObjectContext(myEntityConnection)
Catch ex As Exception
End Try
End Function
Make sure that the storageNS namespace hardcoded value matches the one used in your code, you can view this by debugging the code and examining the storageXML variable to see what was actually used.
Now you can pass a new schema name, and different database connection info at runtime when you create your entities. No more manual .edmx changes required.
Using Context As New JDE_Entities(CreateObjectContext("NewSchemaNameHere", ConnectionString_EntityFramework("ServerName", "DatabaseName", "UserName", "Password"), "JDE_Model"))
Dim myWO = From a In Context.F4801 Where a.WADOCO = 400100
If myWO IsNot Nothing Then
For Each r In myWO
Me.Label1.Text = r.WADL01
Next
End If
End Using

I had a lot of problems getting this to work when using EF6 with an OData Data Service, so I had to find an alternate solution. In my case, I didn't really need to do it on the fly. I could get away with changing the schema when deploying to some test environments, and in the installer.
Use Mono.Cecil to rewrite the embedded .ssdl resources straight in the DLLs. This works just fine in my case.
Here is a simplified example of how you can do this:
var filename = "/path/to/some.dll"
var replacement = "Schema=\"new_schema\"";
var module = ModuleDefinition.ReadModule(filename);
var ssdlResources = module.Resources.Where(x => x.Name.EndsWith(".ssdl"));
foreach (var resource in ssdlResources)
{
var item = (EmbeddedResource)resource;
string rewritten;
using (var reader = new StreamReader(item.GetResourceStream()))
{
var text = reader.ReadToEnd();
rewritten = Regex.Replace(text, "Schema=\"old_schema\"", replacement);
}
var bytes = Encoding.UTF8.GetBytes(rewritten);
var newResource = new EmbeddedResource(item.Name, item.Attributes, bytes);
module.Resources.Remove(item);
module.Resources.Add(newResource);
}
