I have difficulties understanding this example on how to use facets :
https://lucenenet.apache.org/docs/4.8.0-beta00008/api/Lucene.Net.Demo/Lucene.Net.Demo.Facet.SimpleFacetsExample.html
My goal is to create an index in which each document field have a facet, so that at search time i can choose which facets use to navigate data.
What i am confused about is setup of facets in index creation, to
summarize my question : is index with facets compatibile with
ReferenceManager?
Need DirectoryTaxonomyWriter to be actually written and persisted
on disk or it will embedded into the index itself and is just
temporary? I mean given the code
indexWriter.AddDocument(config.Build(taxoWriter, doc)); of the
example i expect it's temporary and will be embedded into the index (but then the example also show you need the Taxonomy to drill down facet). So can the Taxonomy be tangled in some way with the index so that the are handled althogeter with ReferenceManager?
If is not may i just use the same folder i use for storing index?
Here is a more detailed list of point that confuse me :
In my scenario i am indexing the document asyncrhonously (background process) and then fetching the indext ASAP throught ReferenceManager in ASP.NET application. I hope this way to fetch the index is compatibile with DirectoryTaxonomyWriter needed by facets.
Then i modified the code i write introducing the taxonomy writer as indicated in the example, but i am a bit confused, seems like i can't store DirectoryTaxonomyWriter into the same folder of index because the folder is locked, need i to persist it or it will be embedded into the index (so a RAMDirectory is enougth)? if i need to persist it in a different direcotry, can i safely persist it into subdirectory?
Here the code i am actually using :

I have a utility that reads the status of MicrosoftBizTalk Server resources .. specifically the ReceiveLocation component. My problem is that the program is submitting multiple entries of each item i.e each item in the data returned is being multiplied by 25 such that instead of persisting only 5 rows the data being persisted is 125. So for example instead of having just 1 row for my first row returned i have 25.
This is my program :
public List<BizTalk> GetBizTalkServicesStatistics()
{
List<BizTalk> model = new List<BizTalk>();
try
{
//Create the WMI search object.
ManagementObjectSearcher Searcher = new ManagementObjectSearcher();
ConnectionOptions options = new ConnectionOptions
{
Username = "+username+",
Password = "+password+",
Authority = "+domain+"
};
var server = "+server+";
// create the scope node so we can set the WMI root node correctly.
ManagementScope Scope = new ManagementScope("\\\\" + server + "\\root\\MicrosoftBizTalkServer", options);
Searcher.Scope = Scope;
// Build a Query to enumerate the MSBTS_ReceiveLocation instances if an argument
// is supplied use it to select only the matching RL.
//if (args.Length == 0)
SelectQuery Query = new SelectQuery();
Query.QueryString = "SELECT * FROM MSBTS_ReceiveLocation";
// else
//Query.QueryString = "SELECT * FROM MSBTS_ReceiveLocation WHERE Name = '" + args[0] + "'";
// Set the query for the searcher.
Searcher.Query = Query;
// Execute the query and determine if any results were obtained.
ManagementObjectCollection QueryCol = Searcher.Get();
// Use a bool to tell if we enter the for loop
// below because Count property is not supported
bool ReceiveLocationFound = false;
// Enumerate all properties.
foreach (ManagementBaseObject envVar in QueryCol)
{
// There is at least one Receive Location
ReceiveLocationFound = true;
PropertyDataCollection envVarProperties = envVar.Properties;
foreach (PropertyData envVarProperty in envVarProperties)
{
BizTalk bizTalk = new BizTalk();
bizTalk.Name = Convert.ToString(envVar["Name"]);
bizTalk.TransportType = Convert.ToString(envVar["AdapterName"]);
bizTalk.Uri = Convert.ToString(envVar["InboundTransportURL"]);
bizTalk.Status = Convert.ToString(envVar["Name"]);
bizTalk.ReceiveHandler = Convert.ToString(envVar["HostName"]);
bizTalk.ReceivePort = Convert.ToString(envVar["ReceivePortName"]);
bizTalk.RunDate = DateTime.Now;
bizTalk.ApplicationId = 24;
bizTalk.ServerId = 8;
bizTalk.InstanceName = "FBCZOP";
model.Add(bizTalk);
}
}
if (!ReceiveLocationFound)
{
Console.WriteLine("No receive locations found matching the specified name.");
}
}
catch (Exception excep)
{
ExceptionLogger.SendErrorToText(excep);
}
return model;
}
Save Function
public void SaveStatistics(BizTalk entity)
{
List<BizTalk> ServerInfo = new List<BizTalk>();
ServerInfo = GetBizTalkServicesStatistics();
foreach (var di in ServerInfo)
{
entity.RunDate = di.RunDate;
entity.Name = di.Name;
entity.Status = di.Status;
entity.Uri = di.Uri;
entity.InstanceName = di.InstanceName;
entity.ReceivePort = di.ReceivePort;
entity.TransportType= di.TransportType;
entity.RunDate = DateTime.Now;
entity.ReceiveHandler = di.ReceiveHandler;
entity.ServerId = entity.ServerId;
entity.ApplicationId = entity.ApplicationId;
appEntities.BizTalk.Add(entity);
appEntities.SaveChanges();
}
}
When i step through the code variable envVarProperties shows record count as 125 under envVarProperties << ResultsView :
Link 1
whilst QueryCol variable shows count of 5 :
Link 2
It looks like you're iterating an extra time in your GetBizTalkServicesStatistics() method.
Remove the foreach loop that starts with foreach (PropertyData envVarProperty in envVarProperties). This is looping through each property the object has (All 25 properties) for each instance (5 instances)... 25 * 5 = 125 values you are retrieving. You only want to iterate through your instances and pull the properties you want. That way you end up with 5 objects in your model object.
I'd suggest maybe something like this (untested because I don't have BizTalk)
public List<BizTalk> GetBizTalkServicesStatistics()
{
List<BizTalk> model = new List<BizTalk>();
try
{
//Create the WMI search object.
ConnectionOptions options = new ConnectionOptions
{
Username = "+username+",
Password = "+password+",
Authority = "+domain+"
};
var server = "+server+";
// create the scope node so we can set the WMI root node correctly.
ManagementScope Scope = new ManagementScope("\\\\" + server + "\\root\\MicrosoftBizTalkServer", options);
ManagementObjectSearcher Searcher = new ManagementObjectSearcher(Scope, new ObjectQuery("SELECT * FROM MSBTS_ReceiveLocation"));
// Enumerate all properties.
foreach (ManagementObject instance in Searcher.Get())
{
{
BizTalk bizTalk = new BizTalk();
bizTalk.Name = instance.Properties["Name"]?.Value?.ToString();
bizTalk.TransportType = instance.Properties["AdapterName"]?.Value?.ToString();
bizTalk.Uri = instance.Properties["InboundTransportURL"]?.Value?.ToString();
bizTalk.Status = instance.Properties["Name"]?.Value?.ToString();
bizTalk.ReceiveHandler = instance.Properties["HostName"]?.Value?.ToString();
bizTalk.ReceivePort = instance.Properties["ReceivePortName"]?.Value?.ToString();
bizTalk.RunDate = DateTime.Now;
bizTalk.ApplicationId = 24;
bizTalk.ServerId = 8;
bizTalk.InstanceName = "FBCZOP";
model.Add(bizTalk);
}
}
// Determine
if (model.Count == 0)
{
Console.WriteLine("No receive locations found matching the specified name.");
}
}
catch (Exception excep)
{
ExceptionLogger.SendErrorToText(excep);
}
return model;
}
Also, this can be simplified more if you remove the connectionoptions (unless you are hard coding credentials which is highly advised against). If you are just using the identity of the executing user, that data is not needed.

You are adding the same entity 25 times and overwrite its properties by reference. You need to initialize a new entity inside your loop:
foreach (var di in ServerInfo)
{
var entity = new BizTalk();
entity.RunDate = di.RunDate;
entity.Name = di.Name;
entity.Status = di.Status;
entity.Uri = di.Uri;
entity.InstanceName = di.InstanceName;
entity.ReceivePort = di.ReceivePort;
entity.TransportType= di.TransportType;
entity.RunDate = DateTime.Now;
entity.ReceiveHandler = di.ReceiveHandler;
entity.ServerId = entity.ServerId;
entity.ApplicationId = entity.ApplicationId;
appEntities.BizTalk.Add(entity);
appEn.SaveChanges();
}
}
As you don't show the code where "SaveStatistics" is called it's not sure this will fix your complete problem, but it's at least one method that does not do what you expect it to do.
I have content items stored in Ektron that are assigned to taxonomies. I'm trying to create a method that will allow me to programmatically change the taxonomies. So far I find the content item by ID, and I'm able to retrieve its taxonomies, but I'm not sure how to change them.
var ektronItem = contentManager.GetItem((long) item.tctmd_id);
if (ektronItem != null) // item exists in Ektron
{
var newTaxonomies = item.taxonomy_ids;
var taxonomyAPI = new Taxonomy();
var taxData = taxonomyAPI.ReadAllAssignedCategory(ektronItem.Id);
foreach (var tax in taxData)
{
taxonomyAPI.RemoveTaxonomyItem(???);
// here I'm trying to remove the content item from the taxonomy
}
}
taxonomyAPI.RemoveTaxonomyItem() takes a Ektron.Cms.TaxonomyRequest object, but I'm not sure how to create this. I'm also not sure if this is even the method I should be using.
In case anyone else wants to know how to do this, here's the solution I came up with:
var contentManager = new Ektron.Cms.Framework.Content.ContentManager();
var criteria = new Ektron.Cms.Content.ContentCriteria(ContentProperty.Id, EkEnumeration.OrderByDirection.Ascending);
criteria.AddFilter(ContentProperty.FolderId, CriteriaFilterOperator.EqualTo, toUpdate.folder_id);
criteria.OrderByDirection = Ektron.Cms.Common.EkEnumeration.OrderByDirection.Descending;
criteria.OrderByField = Ektron.Cms.Common.ContentProperty.GoLiveDate;
criteria.FolderRecursive = true;
criteria.PagingInfo = new Ektron.Cms.PagingInfo(50, 1);
var ektronItem = contentManager.GetItem((long) item.tctmd_id);
if (ektronItem != null) // item exists in Ektron
{
// update taxonomy in Ektron
var taxIds = item.taxonomy_ids;
var taxonomyAPI = new Taxonomy();
var taxData = taxonomyAPI.ReadAllAssignedCategory(ektronItem.Id);
var taxManager = new Ektron.Cms.Framework.Organization.TaxonomyItemManager();
var taxCriteria = new TaxonomyItemCriteria();
// create a taxonomy criteria of the item ID
taxCriteria.AddFilter(TaxonomyItemProperty.ItemId, CriteriaFilterOperator.EqualTo, item.tctmd_id);
// get all taxonomy items with item ID
var taxItems = taxManager.GetList(taxCriteria);
// determine taxonomyItemType
var type = taxItems.FirstOrDefault().ItemType;
foreach (var tax in taxData)
{
// delete from old taxonomies
taxManager.Delete(tax.Id, (long)item.tctmd_id, type);
}
foreach (var tax in taxIds)
{
// add to new taxonomies
var taxonomyItemData = new TaxonomyItemData()
{
TaxonomyId = tax,
ItemType = type,
ItemId = (long)item.tctmd_id
};
try
{
taxManager.Add(taxonomyItemData);
}
catch (Exception ex)
{
}
}
}
i need copy and paste some records of my table with just but change one field.
here is my code:
using (ClearWhiteDBEntities cwContext = new ClearWhiteDBEntities())
{
var qlstfld = from lstflds in cwContext.tblListFields
where lstflds.listId == theLongSrc
select lstflds;
foreach (var item in qlstfld)
{
tblListField lstFldRow = new tblListField
{
name = item.name,
filterFieldId = item.filterFieldId,
listId = theLongDes, //this field must be change in paste
continueById = item.continueById,
destinationId = item.destinationId,
conditionId = item.conditionId,
userId = userId,
date = Convert.ToDateTime(DateTime.Now.ToShortDateString()),
time = DateTime.Now.TimeOfDay,
IP = trueIp
};
cwContext.AddTotblListFields(lstFldRow);
cwContext.SaveChanges();
}
}
but i get this error:
an error accured white starting a transaction on the provider connection. see the inner exception for details.
what is best solution to copy and paste records but change one field?
If you are using change tracking:
using (ClearWhiteDBEntities cwContext = new ClearWhiteDBEntities())
{
var qlstfld = from lstflds in cwContext.tblListFields
where lstflds.listId == theLongSrc
select lstflds;
foreach (var item in qlstfld)
{
cwContext.ObjectStateManager.ChangeObjectState(item, System.Data.EntityState.Added);
item.Id = 0;
item.listId = theLongDes; //this field must be change in paste
}
cwContext.SaveChanges();
}
I'm hoping someone can help. A long time windows forms/aspx user, moving to WPF.
Not expecting a coded answer to this, but any pointers on a different way to approach would be greatly appreciated - I am probably approaching this in a very backward way.
So the objective is to have an ObservableCollection with sub ObservableCollection "childen" within to then bind to my WPF treeview control.
I can bind my collection to the treeview without issues, and have styled it with checkboxes images as desired, frustratingly, its the ObservableCollection with children of children of children I am having trouble generating in the first place.
I have a table in SQL with LDAP Paths, and various other information I'm storing against that LDAP path, which I read into my ObservableCollection.
Single level, no problem, the bit I'm struggling with is sorted the sub objects of sub objects by LDAP Path, so when I bind to the treeview is presented as AD OU's are structured.
EG:
TopOU
Users
Front Office Users
Helpdesk Users
Example LDAP Paths in my DB
LDAP://OU=Front Office Users,OU=Users,OU=TopOU,DC=dev,DC=local
LDAP://OU=Helpdesk Users,OU=Users,OU=TopOU,DC=dev,DC=local
LDAP://OU=OU=Users,OU=TopOU,DC=dev,DC=local
LDAP://OU=OU=TopOU,DC=dev,DC=local
private ObservableCollection<AssignmentData> OUTreeAssignmentsCollection = new ObservableCollection<AssignmentData>();
public class AssignmentData : INotifyPropertyChanged
{
public Int32 AssignmentID { get; set; }
public String AssignmentName { get; set; }
public AssignmentTypes AssignmentType { get; set; }
//other stuff....
//For TreeView all sub nodes
public ObservableCollection<AssignmentData> Children { get; set; }
}
I then start to read from my db in a rather nasty way, and this is where it all goes wrong, and I could use some pointers.
cmd = new SqlCommand("SELECT UserGroups.UserGroupID, UserGroups.Name, UserGroups.LDAPPath FROM UserGroups WHERE UserGroups.TypeID=1", DBCon);

With my current solution, I get a treeview, with sub nodes of sub nodes, but they are wrong/lots of duplication etc. I have spent literally days trying to fix my probably overcomplicated attempt above - but have come to the conclusion I'm probably going about it the wrong way.
Any help greatly appreciated!
Just having a peruse ;) through your code. Think I can see why you have lots of duplications. Looks like your first SQL query get's all parent/child records. Then the second query will go and get some of those records again, if that makes sense.
One approach would be to only get the top level items in your first query. Possibly by getting SQL to count the number of commas.
SELECT UserGroups.UserGroupID, UserGroups.Name, UserGroups.LDAPPath,
LENGTH(LDAPPath) - LENGTH(REPLACE(LDAPPath, ',', '')) as CommaCount
FROM UserGroups
WHERE UserGroups.TypeID=1
AND CommaCount = 2
Since you asked for different approach id say it's not very efficient to repeatedly query the database in a loop. When I'm building a tree of parent child objects I'd normally get all parent/child records in one query. Build a flat dictionary of all the objects. Then loop through it and make the parent/child associations.
The dictionary can also be useful to lookup your objects later on either directly by key or to loop through without having to make a recursive function that crawls the tree.
So I'd suggest that you break it down into 2 blocks of code.
First block: Using your existing query that get's all of the items, create a flat Dictionary with everything in.
They key of each item should probably be the result from GetLDAPHierarchical().
Second block: Next loop through the dictionary and create the hierarchy. Add anything with no parent directly to the UserOUCollection
foreach(AssignmentData d in myDictionary.Values)
{
String parentKey = GetParentLDAPKey(d.AssignmentLDAPHierarchical);
if (myDictionary.ContainsKey(parentKey))
{
myDictionary(parentKey).children.Add(d);
}
else
{
UserOUCollection.Add(d);
}
}
GetParentLDAPKey() will need to produce the same key as it's parent by removing the first part of the LDAP Path.
Hope that points you in the right direction.

Thanks so much to hman, who pointed me in a much more logical direction. I used LDAPPath as my dictionary key.
Dictionary<String, AssignmentData> OUDictionary = new Dictionary<String, AssignmentData>();
//Read from DB
cmd = new SqlCommand("SELECT UserGroups.UserGroupID, UserGroups.Name, UserGroups.LDAPPath FROM UserGroups WHERE UserGroups.TypeID=1", DBCon);
reader = cmd.ExecuteReader();
while (reader.Read())
{
AssignmentData newItem = new AssignmentData()
{
AssignmentID = Convert.ToInt32(reader[0]),
AssignmentName = reader[1].ToString(),
AssignmentImage = ouIcon,
AssignmentLDAPPath = reader[2].ToString(),
AssignmentCNPath = GetCNFromLDAPPath(reader[2].ToString()),
AssignmentTooltip = GetADSLocationTooltip(reader[2].ToString()),
AssignmentType = AssignmentTypes.UserOU,
};
UserOUDictionary.Add(reader[2].ToString(), newItem);
}
reader.Close();
reader.Dispose();
//Now Read OU List into TreeView Collection
foreach (AssignmentData d in UserOUDictionary.Values)
{
String parentKey = GetParentLDAPPath(d.AssignmentLDAPPath);
if (UserOUDictionary.ContainsKey(parentKey))
{
AssignmentData parentItem = UserOUDictionary[parentKey];
if (parentItem.Children == null) { parentItem.Children = new ObservableCollection<AssignmentData> { d }; } //add first child
else { parentItem.Children.Add(d); } //add more children to exisiting
}
else
{
UserOUCollection.Add(d); //add to root of control
}
}
private String GetParentLDAPKey(String strLDAPPath)
{
String retParentKey = strLDAPPath;
if (strLDAPPath.Contains(","))
{
retParentKey = retParentKey.Replace("LDAP://", "");
retParentKey = retParentKey.Remove(0, retParentKey.IndexOf(",") + 1);
retParentKey = "LDAP://" + retParentKey;
}
return retParentKey;
}
