  • Ruby integer to string key

    - by Gene
    A system I'm building needs to convert non-negative Ruby integers into shortest-possible UTF-8 string values. The only requirement on the strings is that their lexicographic order be identical to the natural order on integers. What's the best Ruby way to do this? We can assume the integers are 32 bits and the sign bit is 0. This is successful: (i >> 24).chr + ((i >> 16) & 0xff).chr + ((i >> 8) & 0xff).chr + (i & 0xff).chr But it appears to be 1) garbage-intense and 2) ugly. I've also looked at pack solutions, but these don't seem portable due to byte order. FWIW, the application is Redis hash field names. Building keys may be a performance bottleneck, but probably not. This question is mostly about the "Ruby way".

  • MySQL - What is the correct primary key method

    - by Hammerstein
    I'm starting to develop an application using MySQL and although I've developed apps before using databases, I've normally gone to the incrementing id method. The other day I was reading a posting somewhere and saw someone being picked apart for this, for not properly "normalising the database". I'm not a big database person, but I wanted to make sure I'm doing this right. Any ideas, help / guidance?

like PersonalInfo,contactInfo,Address there will be only one record, but for tags like "OtherInfo","academicInfo","ProfessionalInfo" there will be multiple records so in xml there are tags for that. now to edit tags having one record only for one user i did coding like: private void FillFamilyInfoControls(XElement rootElement) { ddlSunsign.DataBind(); XElement parentElement; string xPathQuery = "FamilyInfo/Fields"; parentElement = rootElement.XPathSelectElement(xPathQuery); txtGallantryHistory.Text = parentElement.Element("GallantryHistory").Attribute("value").Value; txtEthinicity.Text = parentElement.Element("Ethinicity").Attribute("value").Value; txtKulDev.Text = parentElement.Element("KulDev").Attribute("value").Value; txtKulDevi.Text = parentElement.Element("KulDevi").Attribute("value").Value; txtCaste.Text = parentElement.Element("Caste").Attribute("value").Value; ddlSunsign.SelectedValue = parentElement.Element("SunSignId").Attribute("value").Value; ddlSunsign.SelectedItem.Text = parentElement.Element("SunSignName").Attribute("value").Value; } private XElement UpdateFamilyInfoXML(XElement rootElement) { XElement parentElement; string xPathQuery = "FamilyInfo/Fields"; parentElement = rootElement.XPathSelectElement(xPathQuery); parentElement.Element("GallantryHistory").Attribute("value").Value = txtGallantryHistory.Text; parentElement.Element("Ethinicity").Attribute("value").Value = txtEthinicity.Text; parentElement.Element("KulDev").Attribute("value").Value = txtKulDev.Text; parentElement.Element("KulDevi").Attribute("value").Value = txtKulDevi.Text;

parentElement.Element("SunSignName").Attribute("value").Value = ddlSunsign.SelectedItem.Text; parentElement.Element("ModifiedBy").Attribute("value").Value = UMSession.CurrentLoggedInUser.UserId.ToString(); parentElement.Element("ModifiedOn").Attribute("value").Value = System.DateTime.Now.ToString(); return rootElement; //rootElement.XPathSelectElement(xPathQuery) = parentElement; } these 2 functions i have used to update xml and to get data from xml and fill into controls. but for the tags where there are multiple records... i am not able to find any solution /control using which i an do it easily. coz my field's value is in attribute named "Value" when in the examples i saw its between opening and closing tag.. i have 2 methods to do so. 1 . i make one page to edit a single record and pass id of record to that page on editing. open the page in iframe on same page to edit and in page_load get data from database for id passed and fill it in control. 2 . i store xml on server as physical file and use it in page i opened in iframe to edit the record. so i am confused... can anybody please guide me that what shpould i do to let user provide interface to edit this xml data/user profile ?

My problem is that all users, even those who are not in groupA can access the /home/groupA/Public/Dropbox and see all files. I just want them to be able to put files in there but not see the content of the folder and prohibit them from deleting any files in there. Does anybody have a clue what could be the problem and how I can fix it ?

  • unable to decrypt certain files with secret key pgp 6.5.8, any advice?

    - by pythonian29033
    Ok so I do some stuff for a client of ours that requires me to decrypt some of their suppliers messages, the thing is, something weird happened the other day and I can only decrypt some files with an old decryption script, but for certain files I get the error: "Message is encrypted. Cannot decrypt message. It can only be decrypted by: 2048 bits, Key ID 98627E12, Created 2000-03-02 "Other Guy "" as you can see, the key is ancient and I was still 9years old when it was created, so I have know idea who this "Other Guy" is. . .and I can't understand why I'm able to decrypt some of the supplier's files with the decryption script, but for others it fails. PS: the supplier only uses one public key, so this should work for all the files, any advice?

  • How do I use an SSH public key from a remote machine?

    - by kubi
    Setup The public keys are set up on a Macbook. I can do a passwordless push to github and a server (iMac) on the local network. The Problem I know the keys are partially setup correctly, because I everything works if I'm sitting at the Macbook. What doesn't work is when I SSH into the Macbook remotely and attempt to push to github or to the iMac server. I'm prompted to input my SSH key passphrase. What am I missing to enable pushing to github from the Macbook while logged in remotely from the iMac?

  • Get CruiseControl to talk to github with the correct public key.

    - by Jezmond
    Hi All, Has anybody installed git and ControlControl and got CruiseControl to pull from GitHub on a window 2003 server. I keep getting public key errors (access denied) - Which is good i suppose as that confirms git is talking to github. However what is not good is that I dont not know where to install the rsa keys so they will be picked up by the running process (git in the context of cc.net). Any help would save me a lot of hair! I have tried installing the keys into; c:\Program Files\Git.ssh Whereby running git bash and cd ~ take me to: c:\Program Files\Git Thanks in advance

  • keybinding issues with xmodmap across synergy

    - by Rick
    I've got two systems I use across Synergy. On the main one I have a normal keyboard that I swap caps lock and ctrl for. So I do: xmodmap -e 'keycode 66 = Control_L' xmodmap -e 'clear lock' xmodmap -e 'add Control = Control_L' Where keycode 66 is my caps lock key. The trouble is that I can't get this key to act as a control key on the other machine I connect to with synergy. The strange thing is that if I plug a keyboard into the machine, and run xev, the control key there is keycode 37. When I then hit my modified control key (keycode 66 on the master) it's registering as keycode 37 on the remote machine. So according to xev, it should be picking it up as a control keypress. Anyone have any hints on if Synergy is doing something overly helpful for me?

  • Can Google App users view Exchange users public calendars and contacts?

    - by CT
    My company currently uses MS Exchange 2003 for company email, contacts, and calendars. We have approximately 150 users. Construction industry. I would like to look into migrating from Exchange to Google Apps. It will be an easier sell to the powers that be if we can migrate certain smaller departments first successfully than an entire company move. I would like to first migrate our field superintendents who are usually out of the office working remotely. Approx 30 users. Will Google App users be able to see our Exchange user's calendars and vice versa? How about public folders? Anyone's migration story is much appreciated. Thank you.

  • phpBB - display a public message when the whole board is private

    - by Sparky672
    In my installation all discussion forums/boards are private and can only be seen after a user registers and admin approves their membership. This is working. When a user first comes to the main phpBB page and they're not logged in, they can see very little except for the login and registration functions. Now I'm trying to configure phpBB to display a Read Me posting that is available to general public before registration or login. The problem is that I'd have to create a whole "public" forum and it would likely contain only one topic thread called "Read Me". The users would have to click into the public forum and then click again to get into the Topic called "Read Me". Is it possible to have a Topic thread outside of a forum? If not, is there another, better, way to achieve this? I just want to display a message, maybe a few short paragraphs to the public, explaining the purpose of the Forum and that they must register and wait for approval in order to gain additional access. I'm not seeing anything like this in the ACP. Thank-you.

    My understanding of OAuth (2.0) is that its a software stack and protocol to allow 2+ web apps to share information about a single end user. User A is a member of Site B and Site C; Site B wants to fetch some data from Site C about User A, and this is where OAuth steps in. So first off, if this assessment is incorrect, please begin by clarifying this for me and correcting me! Assuming I'm on the right track, then I guess I'm not seeing the need for OAuth to begin with (!). I'm sure I'm just not seeing the "forest through the trees" here, but the way I see it, couldn't Site C just expose a public API that Site B could use to fetch the same data (sans OAuth)? If Site C required user credentials to access the data, could this public API just use HTTPS for secure transport and require username/password as a part of each API call? Again, I'm sure I'm missing something, but I'm just not understanding why I would need OAuth when a secure, public API written and exposed by Site C seems more than capable of delivering what Site B needs regarding User A. In general, I'm looking for a set of guidelines to go by when deciding to choose between using OAuth for my web apps or just writing my own web service ( exposing public API). Thanks in advance!

  • An Xml Serializable PropertyBag Dictionary Class for .NET

    - by Rick Strahl
    I don't know about you but I frequently need property bags in my applications to store and possibly cache arbitrary data. Dictionary<T,V> works well for this although I always seem to be hunting for a more specific generic type that provides a string key based dictionary. There's string dictionary, but it only works with strings. There's Hashset<T> but it uses the actual values as keys. In most key value pair situations for me string is key value to work off. Dictionary<T,V> works well enough, but there are some issues with serialization of dictionaries in .NET. The .NET framework doesn't do well serializing IDictionary objects out of the box. The XmlSerializer doesn't support serialization of IDictionary via it's default serialization, and while the DataContractSerializer does support IDictionary serialization it produces some pretty atrocious XML. What doesn't work? First off Dictionary serialization with the Xml Serializer doesn't work so the following fails: [TestMethod] public void DictionaryXmlSerializerTest() { var bag = new Dictionary<string, object>(); bag.Add("key", "Value"); bag.Add("Key2", 100.10M); bag.Add("Key3", Guid.NewGuid()); bag.Add("Key4", DateTime.Now); bag.Add("Key5", true); bag.Add("Key7", new byte[3] { 42, 45, 66 }); TestContext.WriteLine(this.ToXml(bag)); } public string ToXml(object obj) { if (obj == null) return null; StringWriter sw = new StringWriter(); XmlSerializer ser = new XmlSerializer(obj.GetType()); ser.Serialize(sw, obj); return sw.ToString(); } The error you get with this is: System.NotSupportedException: The type System.Collections.Generic.Dictionary`2[[System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[System.Object, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]] is not supported because it implements IDictionary. Got it! BTW, the same is true with binary serialization. Running the same code above against the DataContractSerializer does work: [TestMethod] public void DictionaryDataContextSerializerTest() { var bag = new Dictionary<string, object>(); bag.Add("key", "Value"); bag.Add("Key2", 100.10M); bag.Add("Key3", Guid.NewGuid()); bag.Add("Key4", DateTime.Now); bag.Add("Key5", true); bag.Add("Key7", new byte[3] { 42, 45, 66 }); TestContext.WriteLine(this.ToXmlDcs(bag)); } public string ToXmlDcs(object value, bool throwExceptions = false) { var ser = new DataContractSerializer(value.GetType(), null, int.MaxValue, true, false, null); MemoryStream ms = new MemoryStream(); ser.WriteObject(ms, value); return Encoding.UTF8.GetString(ms.ToArray(), 0, (int)ms.Length); } This DOES work but produces some pretty heinous XML (formatted with line breaks and indentation here): <ArrayOfKeyValueOfstringanyType xmlns="http://schemas.microsoft.com/2003/10/Serialization/Arrays" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"> <KeyValueOfstringanyType> <Key>key</Key> <Value i:type="a:string" xmlns:a="http://www.w3.org/2001/XMLSchema">Value</Value> </KeyValueOfstringanyType> <KeyValueOfstringanyType> <Key>Key2</Key> <Value i:type="a:decimal" xmlns:a="http://www.w3.org/2001/XMLSchema">100.10</Value> </KeyValueOfstringanyType> <KeyValueOfstringanyType> <Key>Key3</Key> <Value i:type="a:guid" xmlns:a="http://schemas.microsoft.com/2003/10/Serialization/">2cd46d2a-a636-4af4-979b-e834d39b6d37</Value> </KeyValueOfstringanyType> <KeyValueOfstringanyType> <Key>Key4</Key> <Value i:type="a:dateTime" xmlns:a="http://www.w3.org/2001/XMLSchema">2011-09-19T17:17:05.4406999-07:00</Value> </KeyValueOfstringanyType> <KeyValueOfstringanyType> <Key>Key5</Key> <Value i:type="a:boolean" xmlns:a="http://www.w3.org/2001/XMLSchema">true</Value> </KeyValueOfstringanyType> <KeyValueOfstringanyType> <Key>Key7</Key> <Value i:type="a:base64Binary" xmlns:a="http://www.w3.org/2001/XMLSchema">Ki1C</Value> </KeyValueOfstringanyType> </ArrayOfKeyValueOfstringanyType> Ouch! That seriously hurts the eye! :-) Worse though it's extremely verbose with all those repetitive namespace declarations. It's good to know that it works in a pinch, but for a human readable/editable solution or something lightweight to store in a database it's not quite ideal. Why should I care? As a little background, in one of my applications I have a need for a flexible property bag that is used on a free form database field on an otherwise static entity. Basically what I have is a standard database record to which arbitrary properties can be added in an XML based string field. I intend to expose those arbitrary properties as a collection from field data stored in XML. The concept is pretty simple: When loading write the data to the collection, when the data is saved serialize the data into an XML string and store it into the database. When reading the data pick up the XML and if the collection on the entity is accessed automatically deserialize the XML into the Dictionary. (I'll talk more about this in another post). While the DataContext Serializer would work, it's verbosity is problematic both for size of the generated XML strings and the fact that users can manually edit this XML based property data in an advanced mode. A clean(er) layout certainly would be preferable and more user friendly. Custom XMLSerialization with a PropertyBag Class So… after a bunch of experimentation with different serialization formats I decided to create a custom PropertyBag class that provides for a serializable Dictionary. It's basically a custom Dictionary<TType,TValue> implementation with the keys always set as string keys. The result are PropertyBag<TValue> and PropertyBag (which defaults to the object type for values). The PropertyBag<TType> and PropertyBag classes provide these features: Subclassed from Dictionary<T,V> Implements IXmlSerializable with a cleanish XML format ToXml() and FromXml() methods to export and import to and from XML strings Static CreateFromXml() method to create an instance It's simple enough as it's merely a Dictionary<string,object> subclass but that supports serialization to a - what I think at least - cleaner XML format. The class is super simple to use: [TestMethod] public void PropertyBagTwoWayObjectSerializationTest() { var bag = new PropertyBag(); bag.Add("key", "Value"); bag.Add("Key2", 100.10M); bag.Add("Key3", Guid.NewGuid()); bag.Add("Key4", DateTime.Now); bag.Add("Key5", true); bag.Add("Key7", new byte[3] { 42,45,66 } ); bag.Add("Key8", null); bag.Add("Key9", new ComplexObject() { Name = "Rick", Entered = DateTime.Now, Count = 10 }); string xml = bag.ToXml(); TestContext.WriteLine(bag.ToXml()); bag.Clear(); bag.FromXml(xml); Assert.IsTrue(bag["key"] as string == "Value"); Assert.IsInstanceOfType( bag["Key3"], typeof(Guid)); Assert.IsNull(bag["Key8"]); //Assert.IsNull(bag["Key10"]); Assert.IsInstanceOfType(bag["Key9"], typeof(ComplexObject)); } This uses the PropertyBag class which uses a PropertyBag<string,object> - which means it returns untyped values of type object. I suspect for me this will be the most common scenario as I'd want to store arbitrary values in the PropertyBag rather than one specific type. The same code with a strongly typed PropertyBag<decimal> looks like this: [TestMethod] public void PropertyBagTwoWayValueTypeSerializationTest() { var bag = new PropertyBag<decimal>(); bag.Add("key", 10M); bag.Add("Key1", 100.10M); bag.Add("Key2", 200.10M); bag.Add("Key3", 300.10M); string xml = bag.ToXml(); TestContext.WriteLine(bag.ToXml()); bag.Clear(); bag.FromXml(xml); Assert.IsTrue(bag.Get("Key1") == 100.10M); Assert.IsTrue(bag.Get("Key3") == 300.10M); } and produces typed results of type decimal. The types can be either value or reference types the combination of which actually proved to be a little more tricky than anticipated due to null and specific string value checks required - getting the generic typing right required use of default(T) and Convert.ChangeType() to trick the compiler into playing nice. Of course the whole raison d'etre for this class is the XML serialization. You can see in the code above that we're doing a .ToXml() and .FromXml() to serialize to and from string. The XML produced for the first example looks like this: <?xml version="1.0" encoding="utf-8"?> <properties> <item> <key>key</key> <value>Value</value> </item> <item> <key>Key2</key> <value type="decimal">100.10</value> </item> <item> <key>Key3</key> <value type="___System.Guid"> <guid>f7a92032-0c6d-4e9d-9950-b15ff7cd207d</guid> </value> </item> <item> <key>Key4</key> <value type="datetime">2011-09-26T17:45:58.5789578-10:00</value> </item> <item> <key>Key5</key> <value type="boolean">true</value> </item> <item> <key>Key7</key> <value type="base64Binary">Ki1C</value> </item> <item> <key>Key8</key> <value type="nil" /> </item> <item> <key>Key9</key> <value type="___Westwind.Tools.Tests.PropertyBagTest+ComplexObject"> <ComplexObject> <Name>Rick</Name> <Entered>2011-09-26T17:45:58.5789578-10:00</Entered> <Count>10</Count> </ComplexObject> </value> </item> </properties>   The format is a bit cleaner than the DataContractSerializer. Each item is serialized into <key> <value> pairs. If the value is a string no type information is written. Since string tends to be the most common type this saves space and serialization processing. All other types are attributed. Simple types are mapped to XML types so things like decimal, datetime, boolean and base64Binary are encoded using their Xml type values. All other types are embedded with a hokey format that describes the .NET type preceded by a three underscores and then are encoded using the XmlSerializer. You can see this best above in the ComplexObject encoding. For custom types this isn't pretty either, but it's more concise than the DCS and it works as long as you're serializing back and forth between .NET clients at least. The XML generated from the second example that uses PropertyBag<decimal> looks like this: <?xml version="1.0" encoding="utf-8"?> <properties> <item> <key>key</key> <value type="decimal">10</value> </item> <item> <key>Key1</key> <value type="decimal">100.10</value> </item> <item> <key>Key2</key> <value type="decimal">200.10</value> </item> <item> <key>Key3</key> <value type="decimal">300.10</value> </item> </properties>   How does it work As I mentioned there's nothing fancy about this solution - it's little more than a subclass of Dictionary<T,V> that implements custom Xml Serialization and a couple of helper methods that facilitate getting the XML in and out of the class more easily. But it's proven very handy for a number of projects for me where dynamic data storage is required. Here's the code: /// <summary> /// Creates a serializable string/object dictionary that is XML serializable /// Encodes keys as element names and values as simple values with a type /// attribute that contains an XML type name.

The code implements ReadXml and WriteXml for the IXmlSerializable implementation using old school XmlReaders and XmlWriters (because it's pretty simple stuff - no need for XLinq here). Then there are two helper methods .ToXml() and .FromXml() that basically allow your code to easily convert between XML and a PropertyBag object. In my code that's what I use to actually to persist to and from the entity XML property during .Load() and .Save() operations. It's sweet to be able to have a string key dictionary and then be able to turn around with 1 line of code to persist the whole thing to XML and back. Hopefully some of you will find this class as useful as I've found it. It's a simple solution to a common requirement in my applications and I've used the hell out of it in the  short time since I created it. Resources You can find the complete code for the two classes plus the helpers in the Subversion repository for Westwind.Utilities.

  • Getting key/value pairs from plist-style xml using simplexml in php

    - by Anthony
    Here is an example bit from the xml file: <array> <dict> <key>Name</key> <string>Joe Smith</string> <key>Type</key> <string>Profile</string> <key>Role</key> <string>User</string> <key>Some Number</key> <integer>1</integer> <key>Some Boolean</key> <true/> </dict> </array> I have two separate goals. The first is to extract an array from the dictnode that would look like: [Name] => Joe Smith [Type] => Profile [Role] => User [Some Number] => 1 [Some Boolean] => true It's not crucial that the boolean be included, so if that adds too much complexity, I'd rather just know how to deal with the others for now. The second goal is to be able to select the value node (<string>, <integer>,etc) so that I can change the value. I would need to select it based on the text value of the preceding key element. I think the following XPath should work: //key[.=$keyname]/following-sibling[1] But I'm not sure. Basically, this whole system that Apple uses seems logical, but totally contrary to the XML is supposed to work. If I ran the world, the original XML would look more like: <dict type="array"> <value key="Name" type="string">Joe Smith</value> <value key="Type" type="string">Profile</value> <value key="Role type="string">User</value> <value key="Some Number" type="integer">1</value> <value key="Some Boolean" type="boolean">true</value> </dict> But since it is fairly logical, I am wondering if I'm missing some obvious way of handling it.

  • SQL SERVER – Create Primary Key with Specific Name when Creating Table

    - by pinaldave
    It is interesting how sometimes the documentation of simple concepts is not available online. I had received email from one of the reader where he has asked how to create Primary key with a specific name when creating the table itself. He said, he knows the method where he can create the table and then apply the primary key with specific name. The attached code was as follows: CREATE TABLE [dbo].[TestTable]( [ID] [int] IDENTITY(1,1) NOT NULL, [FirstName] [varchar](100) NULL) GO ALTER TABLE [dbo].[TestTable] ADD  CONSTRAINT [PK_TestTable] PRIMARY KEY CLUSTERED ([ID] ASC) GO He wanted to know if we can create Primary Key as part of the table name as well, and also give it a name at the same time. Though it would look very normal to all experienced developers, it can be still confusing to many. Here is the quick code that functions as the above code in one single statement. CREATE TABLE [dbo].[TestTable]( [ID] [int] IDENTITY(1,1) NOT NULL, [FirstName] [varchar](100) NULL CONSTRAINT [PK_TestTable] PRIMARY KEY CLUSTERED ([ID] ASC) ) GO Reference: Pinal Dave (http://blog.SQLAuthority.com) Filed under: Pinal Dave, Readers Question, SQL, SQL Authority, SQL Constraint and Keys, SQL Query, SQL Scripts, SQL Server, SQL Tips and Tricks, T SQL, Technology

  • What is a "Public DNS registered IP address"?

    - by Emma
    I've been reading this ICANN agreement on new TLDs and it has this section on DNS service availability, which i don't completely understand: Refers to the ability of the group of listed-as-authoritative name servers of a particular domain name (e.g., a TLD), to answer DNS queries from DNS probes. For the service to be considered available at a particular moment, at least, two of the delegated name servers registered in the DNS must have successful results from “DNS tests” to each of their public-DNS registered “IP addresses” to which the name server resolves. If 51% or more of the DNS testing probes see the service as unavailable during a given time, the DNS service will be considered unavailable. I'm not 100% sure of the part in bold: does "public" refer to the DNS or to the IP addesses? It looks like there's a mistake and that the hyphen should have been after "DNS". So basically does it mean "the public IP addresses registered in the DNS"?

  • Cannot add repository key

    - by William Anthony
    I just installed my new laptop with ubuntu 12.04 and when I'm trying to add key, there is a "network unreachable" error. william@ubuntu:~$ gpg --keyserver hkp://keys.gnupg.net --recv-keys 1C4CBDCDCD2EFD2A gpg: requesting key CD2EFD2A from hkp server keys.gnupg.net ?: keys.gnupg.net: Network is unreachable gpgkeys: HTTP fetch error 7: couldn't connect: Network is unreachable gpg: no valid OpenPGP data found. gpg: Total number processed: 0 I'm so sure the keyserver is not down, because I tried it again at my old laptop running ubuntu 11.04 william@william:~$ gpg --keyserver hkp://keys.gnupg.net --recv-keys 1C4CBDCDCD2EFD2A gpg: requesting key CD2EFD2A from hkp server keys.gnupg.net gpg: key CD2EFD2A: "Percona MySQL Development Team <[email protected]>" not changed gpg: Total number processed: 1 gpg: unchanged: 1 Is this a bug?

  • NHibernate Pitfalls: Loading Foreign Key Properties

    - by Ricardo Peres
    This is part of a series of posts about NHibernate Pitfalls. See the entire collection here. When saving a new entity that has references to other entities (one to one, many to one), one has two options for setting their values: Load each of these references by calling ISession.Get and passing the foreign key; Load a proxy instead, by calling ISession.Load with the foreign key. So, what is the difference? Well, ISession.Get goes to the database and tries to retrieve the record with the given key, returning null if no record is found. ISession.Load, on the other hand, just returns a proxy to that record, without going to the database. This turns out to be a better option, because we really don’t need to retrieve the record – and all of its non-lazy properties and collections -, we just need its key. An example: 1: //going to the database 2: OrderDetail od = new OrderDetail(); 3: od.Product = session.Get<Product>(1); //a product is retrieved from the database 4: od.Order = session.Get<Order>(2); //an order is retrieved from the database 5:  6: session.Save(od); 7:  8: //creating in-memory proxies 9: OrderDetail od = new OrderDetail(); 10: od.Product = session.Load<Product>(1); //a proxy to a product is created 11: od.Order = session.Load<Order>(2); //a proxy to an order is created 12:  13: session.Save(od); So, if you just need to set a foreign key, use ISession.Load instead of ISession.Get.

  • Exchange 2010 Mail Enabled Public Folder Unable to Recieve External (anon) e-mail.

    - by Alex
    Hello All, I am having issues with my "Public Folders" mail enabled folders receiving e-mails from external senders. The folder is setup with three Accepted Domains (names changed for privacy reasons): 1 - domain1.com (primary & Authoritative) 2 - domain2.com (Authoritative) 3 - domain3.com (Authoritative) When someone attempts to send an e-mail to [email protected] from inside the organization, the e-mail is received and placed in the appropriate folder. However, when someone tries to send an e-mail from outside the organization (such as a gmail account), the following error message is received: "Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 554 554 Recipient address rejected: User unknown (state 14)." When I try to send an e-mail to the same folder, using the same e-mail address above ([email protected]), but with domain2.com instead of domain3.com, it works as intended (both internal & external). I have checked, double checked, and triple checked my DNS settings comparing those from domain2 & domain3 with them both appearing identical. I have tried recreating the folders in question with the same results. I have also ran Get-PublicFolderClientPermission "\Web Programs\folder" with the following results for user anonymous: RunspaceId : 5ff99653-a8c3-4619-8eeb-abc723dc908b Identity : \Web Programs\folder User : Anonymous AccessRights : {CreateItems} Domain2.com & Domain3.com are duplicates of each other, but only domain2.com works as intended. All other exchange functions are functioning properly. If anyone out there has any suggestions, I would love to hear them. I've just hit a brick wall. Thanks for all your help in advance! --Alex
