I Basically have this, which is working fine:
Ideas = new Mongo.Collection('ideas', {_driver: companyDb});
CompanyDb above is defined as:
companyDbString = 'mongodb://127.0.0.1:27017/demo';
companyDb = new MongoInternals.RemoteCollectionDriver(companyDbString);
However, how would i change the driver for the Meteor users collection. I've tried this:
Meteor.users = new Mongo.Collection('users', {_driver: companyDb});
But it gives the expected 'Error: There is already a collection named "users"' error.
I know this sounds like a strange use case, but 'companyDb' changes as the subdomain changes in my application. So I basically need a separate mongo database per sub domain
Try this
AnotherUsersCollection = new Mongo.Collection(“users”, { _driver: companyDb });
or
var remote = 'mongoURL';
database = new MongoInternals.RemoteCollectionDriver(remote);
You can perform database operations with your database object, like so.
database.mongo.findOne('users', "selector_object")
An example might be
database.mongo.findOne('users', {emails : {$elemMatch : {address : "email_string"} } } )

I'm newbie in SQLite.
I would like to query my SQLite database to get multiple rows.
When I add a new item in my local database I call this method Add:
public bool Add<T>(string key, T value)
{
return this.Insert(new SQliteCacheTable(key, this.GetBytes(value))) == 1;
}
_simpleCache.Add("favorite_1", data1);
_simpleCache.Add("favorite_2", data2);
_simpleCache.Add("favorite_3", data2);
Then,
I would like to retrieve from local database all entries where key starts with "favorite_"
to returns all objects in the database which are "favorite" objects.
I'm experienced in Linq, and I would like to do something like this:
IEnumerable<Element> = repository.Find((element) => element.Key.StartWith("favorite_"))
In the SQLiteConnection class there is a method like this:
SQLite.Net.SQLiteConnection.Find<T>(System.Linq.Expressions.Expression<System.Func<T,bool>>)
But I would like the same with in returns a collection IEnumerable<T>.
Can you help me please?
Thank you.

You have to build your query on the table itself, not the connection:
Assuming:
SQLiteConnection repository;
Then the code would look like:
var favorites = repository.Table<SQliteCacheTable>().Where(item => item.StartsWith("favorite_"));
The favorites variable is of type TableQuery<SQliteCacheTable> though, so it does not yet contain your data. The execution of the actual SQL query will be deferred until you try to access the results (by enumerating with foreach or converting to a list with ToList, for example).
To actually observe what's going on on the database, you can turn on tracing in sqlite-net, by setting repository.Trace = true on your SQLiteConnection object.
Finally, it's worth mentioning that you can also use the C# query syntax on TableQuery<T> objects, if your comfortable with it. So your query could become:
var favorites = from item in repository.Table<SQliteCacheTable>()
where item.StartsWith("favorite_")
select item;
I'm trying to get a list of the available users from the Core Service. I spend quite some time looking at the available service methods and the most obvious seemed to be this:
TrusteesFilterData trusteesFilterData = new TrusteesFilterData
{
BaseColumns = ListBaseColumns.IdAndTitle,
IsPredefined = false,
ItemType = ItemType.User
};
XElement listTrustees = client.GetSystemWideListXml(trusteesFilterData);
However, the code throws an error when calling GetSystemWideListXml - Unable to create Abstract Class. Am I using the correct approach and, if so what am I doing wrong? If not, what should I be doing instead?
Take a look at the samples in the open source project for workflow notification
http://code.google.com/p/tridion-notification-framework/source/browse/NotificationService/NotificationService/Worker.cs
Lines 22 - 26 in the DoWork() method should do what you need - I think need to use UsersFilterData rather than TrusteesFilterData
var users = client.GetSystemWideList(new UsersFilterData { BaseColumns = ListBaseColumns.IdAndTitle, IsPredefined = false });
Can anyone provide me with a .NET (C# / VB) sample of how to get all mailboxes that I have access to ?
I have only been able to get my OWN mailbox via EWS - not ALL THE OTHER mailboxes that I also have access to through Outlook.
I don't have the names nor the id's of these mailboxes but isn't it possible to retrieve ALL mailboxes - including my own - that I am allowed to see - just as I can in Outlook ?
I am using Autodiscover to get my mailbox like this: service.AutodiscoverUrl("xxxx#ee.dd") - this will perhaps only get my own mailbox and not all the rest?
Please help !?
The way I got around this was to define the group mailbox in question as a "mailbox" object and then obtain the FolderID for the particular folder.
Define mailbox object
Mailbox gpmailbox = new Mailbox("mailbox#yourdomainname.com");
Get the FolderID (in this case, the Inbox)
FolderId gpInbox = new FolderId(WellKnownFolderName.Inbox, gpmailbox);
Use FolderID in your normal code (in this case I'm obtaining 100 messages)
ItemView view = new ItemView(100);
FindItemsResults<Item> results = hookToServer.FindItems(new FolderId(WellKnownFolderName.Inbox, gpmailbox), view);
The key is to grab the FolderID of the folder you need. Hope this helps.
Edit: I also failed to note that my object "hookToServer" is simply the ExchangeService object. Here's how I defined it:
ExchangeService hookToServer = new ExchangeService(ExchangeVersion.Exchange2010_SP1);
hookToServer.UseDefaultCredentials = true;
hookToServer.Url = new Uri("TheExchangeServer")
I also used this as reference:
EWS 2007 Group Mailbox Guide
You can do this by Using Autodiscover to get user settings, this is a completely separate service to the one with the AutodiscoverUrl method.
The setting name you need is AlternateMailboxes, this will give a collection of all the 'other' mailboxes you have access to. You might then add the user's default mailbox to get a complete list.
In c#:
using Microsoft.Exchange.WebServices.Autodiscover; // from nuget package "Microsoft.Exchange.WebServices"
internal List<string> GetAccessibleMailboxes()
{
AutodiscoverService autodiscoverService = new AutodiscoverService("outlook.office365.com");
autodiscoverService.Credentials = networkCredential;
var userSmtpAddress = networkCredential.UserName;
GetUserSettingsResponse userresponse = autodiscoverService.GetUserSettings(
userSmtpAddress,
UserSettingName.AlternateMailboxes);
var alternateMailboxCollection = (AlternateMailboxCollection)userresponse.Settings[UserSettingName.AlternateMailboxes];
var smtpAddressList = alternateMailboxCollection.Entries.ToList().Select(a => a.SmtpAddress).ToList();
smtpAddressList.Add(userSmtpAddress);
return smtpAddressList;
}
So I managed to get some code rolling for updating the AD from an external sourced. However, I'm a bit confused about how it works.
I have a person with sAMAccount xxxx existing in different OUs.
Now, I only want to update the info in a specific OU, so I put that in my LDAP path. Still, it seem that the info has been updated in different OU's as well?
Could that be possible? Is it because there's only one "Person" object, or do the "GetDirectoryEntry()" not put me where I thought in the tree? Or.. am I only imagine and the weird things I see is becausde of something else.
Some code
DirectoryEntry entry = new DirectoryEntry(LDAP://my.path/ou=myou, dc=my, dc=path);
entry.Username = myUser
entry.Password = myPass
DirectorySearcher searcher = new DirectorySearcher(entry);
searcher.Filter = #"(&(objectClass=Person)(SamAccountname=" + person.id + "))";
SearchResult result = searcher.FindOne();
try
{
DirectoryEntry user = result.GetDirectoryEntry();
user.Properties["displayName"].Value = person.DisplayName;
user.Properties["givenName"].Value = person.Firstname;
user.CommitChanges();
user.Close();
}
catch (DirectoryServicesCOMException ex)
EDIT: It did update the Person object in all the OU's. So either the Person object is one and the same in the whole AD, whick makes my attempt to update them in only the specific OU pointless, or does the "result.GetDirectoryEntry" ignore the fact that I thought I was working only in my specific OU declared in my LDAP path.
Functionality confirmed, still wonder why I needed a specific test-ou since it's still the same users. Anyway, here we go!
So I'm starting out with EF on my website (C#) and Ive run into a bit of a snag. A user can either create or modify data and they will do that with the selection screen (page 1). If a user selects to create new data, I will perform the following code:
Program newProg = new Program();
using (DatabaseEntities context = new DatabaseEntities())
{
Guid id = new Guid(list.SelectedValue);
var itemString = from item in context.Set where item.Id == id select item;
Item selectedItem = itemString.ToList()[0];
newProg.Items.Add(selectedItem);
context.AddToProgramSet(newProg);
context.Detach(newProg);
}
Pretty much creating a new instance of the 'Program' which will be passed along each user control until the user is ready to submit to the database. At that point the following code will be executed:
using (DatabaseEntities context = new DatabaseEntities())
{
context.AddToProgramSet(this.SummaryControl.SelectedProgram);
context.SaveChanges();
}
Unfortunately when I get there, I receive the following message:
The object cannot be added to the ObjectStateManager because it already has an EntityKey. Use ObjectContext.Attach to attach an object that has an existing key.
at this line:
context.AddToProgramSet(this.SummaryControl.SelectedProgram);
Also, when I add the following line prior to the previous:
context.Attach(this.SummaryControl.SelectedProgram);
I get this error:
An object with a null EntityKey value cannot be attached to an object context.
Any help would be greatly appreciated. Thanks.
The root cause of this error is that you are attempting to add an Entity as a new Entity that already has its primary key set.
At what point do you add the Entities to your SummaryControl? Your first code snippet shows you adding the Entity:
...
newProg.Items.Add(selectedItem);
context.AddToProgramSet(newProg);
context.Detach(newProg);
...
Then you appear to add it again:
using (DatabaseEntities context = new DatabaseEntities())
{
context.AddToProgramSet(this.SummaryControl.SelectedProgram);
context.SaveChanges();
}
If newProg and this.SummaryControl.SelectedProgram are the same Entity, you've attempted to add it twice. Remove the context.AddToProgramSet(newProg); from the first snippet, do you work on the Entity, then add it to the ProgramSet.
Dave is right that the root cause is that the entity already has a primary key.
One thing that you do not show in your code is how:
Program newProg = new Program();
Becomes:
this.SummaryControl.SelectedProgram
One way that you could fix it is by saving newProg to the database before you start adding Items to it.
