• c# Active Directory via WMI

  - by Juri Bogdanov

  Hi! Does anyone has some example about accessing Active Directory, LDAP querying using WMI (System.Management namespace) and not System.DirectoryServices namespace. Here on MSDN page it is described a little using CIM classes http://msdn.microsoft.com/en-us/library/aa392320(v=VS.85).aspx But I cant find some C# example realizing it. For example, to access some Win32 class you have to initialize Scope object to use CIMV2 namespace private ConnectionOptions connection; private ManagementScope scope; ... connection = new ConnectionOptions(); ... scope = new ManagementScope("\\\\" + computer + "\\root\\CIMV2", connection); try { scope.Connect(); } And use ObjectQuery class for querying WMI data ObjectQuery objectQuery = new ObjectQuery("SELECT Name FROM Win32_Processor"); ManagementObjectSearcher searcher = ManagementObjectSearcher(scope, objectQuery); foreach (ManagementObject queryObj in searcher.Get()) { return queryObj["Name"].ToString(); } How is it possible to access AD using the same scope? Thanks :)

• Error connecting to exchange mailbox using WebDav

  - by Warda

  We have a windows service that uses the “WebDAV .NET for Exchange” libraries to access the mail server. The WebDav libraries attempts to access the mailbox to process mails. The Error occurs on attempting to retrieve the mailbox contents. The Code snippet below is how the code retrieves the mailbox contents: NetworkCredential credential = new NetworkCredential(Username, Password, Domain); WebdavSession session = new WebdavSession(credential); session.UserMailbox = MailServerURL; Resource resource = new Resource(session); if (UseFormsBasedAuthentication) resource.PerformFormsBasedAuthentication(https://owa.domain.company.org/[email protected]/Inbox"); Mailbox myMailbox = resource.Mailbox; Calling the “resource.Mailbox” raises the following exception: --- System.Net.WebException: The remote server returned an error: (405) Method Not Allowed. at System.Net.HttpWebRequest.GetResponse() at Independentsoft.Webdav.Exchange.Resource.a(String A_0, PropertyName[] A_1) at Independentsoft.Webdav.Exchange.Resource.e(String A_0) at Independentsoft.Webdav.Exchange.Resource.get_Mailbox() at Any helps will be more than appreciated. Thanks

• File I/O OS handling

  - by Albinoswordfish

  This isn't a direct coding question but more of a OS handling mechanism. I was reading somebody's previous question regarding C# and file handling. Apparently C# was throwing an exception regarding a file being locked when trying to access this. So my question is, does C# use an internal lock to handle file I/O between processes, or does the OS use some type of mutual exclusion for file I/O? From what I learned about operating systems, well at least unix, is that the OS doesn't implement any type of mutual exclusion for processes trying to access the same file.

• Help with Linq Expression - INotifyPropertyChanged

  - by Stephen Patten

  Hello, I'm reading the source code from the latest Prism 4 drop and am interested in solving this problem. There is a base class for the ViewModels that implements INotifyPropertyChanged and INotifyDataErrorInfo and provides some refactoring friendly change notification. protected void RaisePropertyChanged<T>(Expression<Func<T>> propertyExpresssion) { var propertyName = ExtractPropertyName(propertyExpresssion); this.RaisePropertyChanged(propertyName); } private string ExtractPropertyName<T>(Expression<Func<T>> propertyExpresssion) { if (propertyExpresssion == null) { throw new ArgumentNullException("propertyExpression"); } var memberExpression = propertyExpresssion.Body as MemberExpression; if (memberExpression == null) { throw new ArgumentException("The expression is not a member access expression.", "propertyExpression"); } var property = memberExpression.Member as PropertyInfo; if (property == null) { throw new ArgumentException("The member access expression does not access property.","propertyExpression"); } if (!property.DeclaringType.IsAssignableFrom(this.GetType())) { throw new ArgumentException("The referenced property belongs to a different type.", "propertyExpression"); } var getMethod = property.GetGetMethod(true); if (getMethod == null) { // this shouldn't happen - the expression would reject the property before reaching this far throw new ArgumentException("The referenced property does not have a get method.", "propertyExpression"); } if (getMethod.IsStatic) { throw new ArgumentException("The referenced property is a static property.", "propertyExpression"); } return memberExpression.Member.Name; } and as an example of it's usage private void RetrieveNewQuestionnaire() { this.Questions.Clear(); var template = this.questionnaireService.GetQuestionnaireTemplate(); this.questionnaire = new Questionnaire(template); foreach (var question in this.questionnaire.Questions) { this.Questions.Add(this.CreateQuestionViewModel(question)); } this.RaisePropertyChanged(() => this.Name); this.RaisePropertyChanged(() => this.UnansweredQuestions); this.RaisePropertyChanged(() => this.TotalQuestions); this.RaisePropertyChanged(() => this.CanSubmit); } My question is this. What would it take to pass an array of the property names to an overloaded method (RaisePropertyChanged) and condense this last bit of code from 4 lines to 1? Thank you, Stephen

• Uploading image file from website on yahoo server causes 410 gone error message when trying to acces

  - by creocare

  I have a form that lets users upload a photo of themselves. This seems to work. The photo does exist on the server once uploaded. When I try to access the file I get a "403 forbidden - you don't have permission to access this url on this sever" and also I get "Additionally, a 410 Gone error was encountered while trying to use an ErrorDocument to handle the request." This is the code I have for uploading the image. $target_path = "images/"; $target_path = $target_path . basename( $_FILES['uploadpic']['name']); if(move_uploaded_file($_FILES['uploadpic']['tmp_name'], $target_path)) { echo "The file ". basename( $_FILES['uploadpic']['name']). " has been uploaded"; } else { echo "There was an error uploading the file, please try again!"; }

• accessing a static property via COM

  - by joreg

  is it possible to access a static property of a COM object without creating an instance of the object? my situation is this: i have an unmanaged application (written in delphi). this application exposes a COM-based plugininterface. until now i only wrote managed plugins in c#. plugins provide their info (name, author, ..) via a static property that returns an instance of PluginInfo (which implements IPluginInfo). this static property i can access on the managed plugins using http://managedvcl.com. now i want to write unmanaged plugins on the same interface. i can load them using: plug := CreateComObject(TGuid) as IMyPlugInterface; and they run, but i don't know how to read out their PluginInfo. so the question again is: is there another way than implementing IPluginInfo in the plugin-class and only accessing the info after i have created an instance of the plugin?

• mysql: how to set max_allowed_packet for shared hosting?

  - by Sadi

  Hello, I need to set (increase) max_allowed_packet. But the problem is I am using a shared hosting. So, I can not access the .ini or .cnf file. Also I can not use the SET command. How can I am able to set a value (actually increase) for the max_allowed_packet, without asking the hosting support. I have no SSH access there. EDIT: I am trying to use VB 4.0.3. In there the attachment size is limited by it. So, I do not think splitting the file can be an option in this case. Thank you Sadi

• How can I block based on URL (from address bar) in a safari extension

  - by PerilousApricot

  I'm trying to write an extension that will block access to (configurable) list of URLs if they are accessed more than N times per hour. From what I understand, I need to have a start script pass a "should I load this" message to a global HTML page (who can access the settings object to get the list of URLs), who will give a thumbs up/thumbs down message back to the start script to deny/allow loading. That works out fine for me, but when I use the usual beforeLoad/canLoad handlers, I get messages for all the sub-items that need to be loaded (images/etc..), which screws up the #accesses/hour limit I'm trying to make. Is there a way to synchronously pass messages back and forth between the two sandboxes so I can tell the global HTML page, "this is the URL in the window bar and the timestamp for when this request came in", so I can limit duplicate requests? Thanks!

• post commit hook fail

  - by jarad mayers

  I have Master/Slave setup using Win2k8R with SVN 1.6.9 and using TortoiseSVN 1.6.7. The access is through Apache and using http. Everything works but when I commit I get the following message: Error: post-commit hook failed (exit code 1) with output: Error: The process cannot access the file because it is being used by another process. This happen when using multiple TortoiseSVN dialog for committing the files in rapid succession. If I use one TortoiseSVN dialog and wait till the commit reply is back then I won't see the problem. In other words, committing one at the time cause no issue. The post-commit script output is logged. Even though I get the above error but when I check the Master and Slave repository the files have been replicated okay with no issue. I am wondering how this issue can be solved.

• JSON - msg.d is undefined error

  - by Narmatha Balasundaram

  Hi - Webmethod returns an array of objects - something like this {"d": [[{"Amount":100,"Name":"StackOverflow"}, {"Amount":200,"Name":"Badges"}, {"Amount":300,"Name":"Questions"}]]} On the client-side, when the JSON is referenced using msg.d, I get a msg.d is undefined error. I am using jQuery JavaScript Library v1.4.2 How do I access the elements in the array of objects? Adding more findings, code and questions: I don't see __type in the JSON object that is returned. Does that mean that the object sent from the server is not JSON formatted? When the __type is not a part of the response, I will not be able to use msg.d? (msg.d is undefined) Some more: 1. I can access the elements from client side using msg[0][0].Amount - How can I specifically JSON format my return object (from the server)

• what is the global.asax Application_Start equivalent when using WAS in IIS7

  - by Mike Tours

  Hi I'd like to use the netTcpBinding for my WCF application which is currently hosted in IIS7, which means configuring it to use WAS instead. This is fairly straight forward however, my application previously made use of the Application_Start event in the global.asax file. I do not require access to the httpContext(which I understand access has been removed in IIS7), however I would still like to hook into the start or init methods? Does an equivalent exist when hosting an application in WAS as apposed to IIS7? Using classic mode is not an option(again I'm not interested in the httpcontext and this only appears to work if using an http binding) - and I've seen an example of putting a static class instide the app_code folder which looks like a horrible hack.

• How do I connect to mysql from php ?

  - by roberto

  Hi guys. I'm working through examples from a book on php/mysql development. I'm working on a linux/apache environment. I've set up a database and a user. I attempt to connect with this line of code: $db_server = mysql_connect($db_hostname, $db_username, $db_password); I get this error: Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'www-data'@'localhost' (using password: YES) in /var/www/hosts/dj/connect.php on line 3 unable to connect to database: Access denied for user 'www-data'@'localhost' (using password: YES) I can only guess what is happening here: I think www-data is a username for apache. Upon the database connection, the credentials being passed in to mysql are not those of my database user, but rather apache's own credentials. Is that what is happening here? How do I pass in the credentials I've defined for my user ?

• Rails, REST Architecture and HTML 5: Cross domain requests with pre-flight requests

  - by Orion

  While working on a project to make our site HTML 5 friendly, we were eager to embrace the new method for Cross Domain requests (no more posting through hidden iframes!!!). Using the Access Control specification we begin setting up some tests to verify the behaviour of various browsers. The current Rails RESTful architecture relies on the four HTTP verbs: GET, POST, PUT, DELETE. However in the Access Control spec, it dictates that non-simple methods (PUT, DELETE) require a pre-flight request using the HTTP verb OPTIONS. In addition during testing we discovered that Firefox 3.5.8 pre-flight POST requests as well. My question is this. Is anyone aware of any project for the Rails framework working to address the issue? If not, any opinions about the best strategy to support the OPTIONS method, since it has to support the routes for all the POST, PUT, DELETE methods?

• Subdomains for different applications on Windows Server 2008 R2 with Apache and IIS 7 installed

  - by Yusuf

  Hi, I have a home server, on which I have installed Apache, and several other applications that have a Web GUI (JDownloader, Free Download Manager). In order to access each of these apps (whether be it from the local network or the Internet), I have to enter a different port, e.g., http:// server:8085 or http:// xxxx.dyndns.org:8085 for Apache, http:// server:90 or http:// xxxx.dyndns.org:90 for FDM, http:// server:8081 or http:// xxxx.dyndns.org:8081 for JDownloader. I would like to be able to access them using sub-domains, e.g, http:// apache.server or http:// apache.xxxx.dyndns.org for Apache, http:// fdm.server or http:// fdm.xxxx.dyndns.org for FDM, http:// jdownloader.server or http:// jdownloader.xxxx.dyndns.org for JDownloader. First of all, would it be possible like I want it, i.e., both from LAN and Internet, and if yes, how? And then, even if it's possible only for Internet, I would like to know how to do it, if there's a way. Thanks in advance, Yusuf

• Which layer should create DataContext?

  - by Kevin

  I have a problem to decide which layer in my system should create DataContext. I have read a book, saying that if do not pass the same DataContext object for all the database updates, it will sometimes get an exception thrown from the DataContext. That's why i initially create new instance of DataContext in business layer, and pass it into data access layer. So that the same datacontext is used for all the updates. But this lead to one design problem, if i wanna change my DAL to Non-LinqToSQL in future, i need to re-write the code in business layer as well. Please give me some advice on this. Thanks. Example code 'Business Layer Public Sub SaveData(name As String) Using ts AS New TransactionScope() Using db As New MyDataContext() DAL.Insert(db,name) DAL.Insert(db,name) End Using ts.Complete() End Using End Sub 'Data Access Layer Public Sub Insert(db as MyDataContext,name As string) db.TableAInsert(name) End Sub

• HttpWebRequest socket operation during WPF binding in a property getter

  - by wpfwannabe

  In a property getter of a C# class I am doing a HTTP GET using HttpWebRequest to some https address. WPF's property binding seems to choke on this. If I try to access the property in a simple method e.g. Button_Clicked, it works perfectly. If I use WPF binding to access the same property, the app seems to be blocked on a socket's recv() method indefinitely. Is it a no-no to do this sort of thing during binding? Is app in some special state during binding? Is there an easy way for me to overcome this limitation and still maintain the same basic idea?

• Group SQL tables in SQL Server Management Studio object explorer

  - by MainMa

  I have a table which has approximately sixty tables, and other tables are added constantly. Each table is a part of a schema. A such quantity of tables makes it difficult to use Microsoft SQL Server Management Studio 2008. For example, I must scroll up in object explorer to access database related functions, or scroll down each time I need to access Views or Security features. Is it possible to group several tables to be able to expand or collapse them in Object Explorer? Maybe a folder may be displayed for each schema, letting collapse the folders I don't need to use?

• Easiest way to retrofit retry logic on LINQ to SQL migration to SQL Azure

  - by Pat James

  I have a couple of existing ASP .NET web forms and MVC applications that currently use LINQ to SQL with a SQL Server 2008 Express database on a Windows VPS: one VPS for both IIS and SQL. I am starting to outgrow the VPS's ability to effectively host both SQL and IIS and am getting ready to split them up. I am considering migrating the database to SQL Azure and keeping IIS on the VPS. After doing initial research it sounds like implementing retry logic in the data access layer is a must-do when adopting SQL Azure. I suspect this is even more critical to implement in my situation where IIS will be on a VPS outside of the Azure infrastructure. I am looking for pointers on how to do this with the least effort and impact on my existing code base. Is there a good retry pattern that can be applied once at the LINQ to SQL data access layer, as opposed to having to wrap all of my LINQ to SQL operations in try/catch/wait/retry logic?
