• Team Foundation Server Setup/Access

  - by Angel Brighteyes

  What I need: A TFS 2010 Setup that allows 2 application developers to access the TFS from remote locations. How it is setup: Server 2008 Standard 2g Ram 300g HD space SharePoint Server 2007, using SQL Server 2005 SQL Server 2008 Standard Team Foundation Server 2010 IIS 7 Sharepoint Bindings: TFS.DynAccount.Me:80; TFS:80 TFS Bindings: TFS.DynAccount.Me:8080; TFS:8080 Using DynDNS service to account for the dynamic ip address being used, this is a requirement for the moment until I can get a better isp package. Access using Local Accounts Server is not setup on a domain, or as a domain. Consequently I did not setup AD services. Problem: When logged into TFS using my credentials TFS\AdminUser through the DynDNS account TFS.DynAccount.Me I recieve the 'Red X of Death' on the Documents and Reports folder. When logged into the TFS through the local peer to peer network using the same credentials TFS\AdminUser I do not receive the 'Red X of Death' problem. Further Troubleshooting: When users 'Right Click' the 'TeamProject1' Click 'Show Project Portal' it tries to take them to http://TFS:8080 instead of http://TFS.DynAccount.Me:8080, which doing further research I am assuming that it is because team foundation server was setup with a local name of TFS instead of 'TFS.DynAccount.Me' as specified here in Visual Studio Magazines: The Red X of Death. Users can Access the Team Portal for SharePoint via http://TFS.DynAccount.Me/TeamCollection/TeamProject so it is not like we are dead in the water or anything. However, as most employees/staff are prone to do, they have expressed a great distaste for having to do it this way and just be patient until the current project is finished since we are under a very strict deadline. Is there a way to set this up differently, or change some settings someplace, reinstall it, point a CName record for our domain website to the DynAccount (e.g. TFS.OurDomain.com points to TFS.DynAccount.Me, which consequently does allow access to the http site without issues), or something. I really don't feel like after all the time and effort I have spent into, first the cost, second the bloody install, third learning SharePoint well enough, fourth the hours into days spent on this, fifth more troubleshooting, sixth employee headaches to just let it lay where it is at. I figure in my spare/off time I would keep trying to get this to work. So I really appreciate any help any one can give me. I know this is probably something really stupid simple that I will 'Face Palm' over, but at the moment the stress and frustration just has me beat. Thank you again, this community has always been a great help.

• Squid proxy not serving modified html content

  - by Matthew

  I'm trying to use squid to modify the page content of web page requests. I followed the upside-down-ternet tutorial which showed instructions for how to flip images on pages. I need to change the actual html of the page. I've been trying to do the same thing as in the tutorial, but instead of editing the image I'm trying to edit the html page. Below is a php script I'm using to try to do it. All jpg images get flipped, but the content on the page does not get edited. The edited index.html files written contain the edited content, but the pages the users receive don't contain the edited content. #!/usr/bin/php <?php $temp = array(); while ( $input = fgets(STDIN) ) { $micro_time = microtime(); // Split the output (space delimited) from squid into an array. $temp = split(' ', $input); //Flip jpg images, this works correctly if (preg_match("/.*\.jpg/i", $temp[0])) { system("/usr/bin/wget -q -O /var/www/cache/$micro_time.jpg ". $temp[0]); system("/usr/bin/mogrify -flip /var/www/cache/$micro_time.jpg"); echo "http://127.0.0.1/cache/$micro_time.jpg\n"; } //Don't edit files that are obviously not html. $temp[0] contains url of file to get elseif (preg_match("/(jpg|png|gif|css|js|\(|\))/i", $temp[0], $matches)) { echo $input; } //Otherwise, could be html (e.g. `wget http://www.google.com` downloads index.html) else{ $time = time() . microtime(); //For unique directory names $time = preg_replace("/ /", "", $time); //Simplify things by removing the spaces mkdir("/var/www/cache/". $time); //Create unique folder system("/usr/bin/wget -q --directory-prefix=\"/var/www/cache/$time/\" ". $temp[0]); $filename = system("ls /var/www/cache/$time/"); //Get filename of downloaded file //File is html, edit the content (this does not work) if(preg_match("/.*\.html/", $filename)){ //Get the html file contents $contentfh = fopen("/var/www/cache/$time/". $filename, 'r'); $content = fread($contentfh, filesize("/var/www/cache/$time/". $filename)); fclose($contentfh); //Edit the html file contents $content = preg_replace("/<\/body>/i", "<!-- content served by proxy --></body>", $content); //Write the edited file $contentfh = fopen("/var/www/cache/$time/". $filename, 'w'); fwrite($contentfh, $content); fclose($contentfh); //Return the edited page echo "http://127.0.0.1/cache/$time/$filename\n"; } //Otherwise file is not html, don't edit else{ echo $input; } } } ?>

• What might cause the big overhead of making a HttpWebRequest call?

  - by Dimitri C.

  When I send/receive data using HttpWebRequest (on Silverlight, using the HTTP POST method) in small blocks, I measure the very small throughput of 500 bytes/s over a "localhost" connection. When sending the data in large blocks, I get 2 MB/s, which is some 5000 times faster. Does anyone know what could cause this incredibly big overhead? Update: I did the performance measurement on both Firefox 3.6 and Internet Explorer 7. Both showed similar results. Update: The Silverlight client-side code I use is essentially my own implementation of the WebClient class. The reason I wrote it is because I noticed the same performance problem with WebClient, and I thought that the HttpWebRequest would allow to tweak the performance issue. Regrettably, this did not work. The implementation is as follows: public class HttpCommChannel { public delegate void ResponseArrivedCallback(object requestContext, BinaryDataBuffer response); public HttpCommChannel(ResponseArrivedCallback responseArrivedCallback) { this.responseArrivedCallback = responseArrivedCallback; this.requestSentEvent = new ManualResetEvent(false); this.responseArrivedEvent = new ManualResetEvent(true); } public void MakeRequest(object requestContext, string url, BinaryDataBuffer requestPacket) { responseArrivedEvent.WaitOne(); responseArrivedEvent.Reset(); this.requestMsg = requestPacket; this.requestContext = requestContext; this.webRequest = WebRequest.Create(url) as HttpWebRequest; this.webRequest.AllowReadStreamBuffering = true; this.webRequest.ContentType = "text/plain"; this.webRequest.Method = "POST"; this.webRequest.BeginGetRequestStream(new AsyncCallback(this.GetRequestStreamCallback), null); this.requestSentEvent.WaitOne(); } void GetRequestStreamCallback(IAsyncResult asynchronousResult) { System.IO.Stream postStream = webRequest.EndGetRequestStream(asynchronousResult); postStream.Write(requestMsg.Data, 0, (int)requestMsg.Size); postStream.Close(); requestSentEvent.Set(); webRequest.BeginGetResponse(new AsyncCallback(this.GetResponseCallback), null); } void GetResponseCallback(IAsyncResult asynchronousResult) { HttpWebResponse response = (HttpWebResponse)webRequest.EndGetResponse(asynchronousResult); Stream streamResponse = response.GetResponseStream(); Dim.Ensure(streamResponse.CanRead); byte[] readData = new byte[streamResponse.Length]; Dim.Ensure(streamResponse.Read(readData, 0, (int)streamResponse.Length) == streamResponse.Length); streamResponse.Close(); response.Close(); webRequest = null; responseArrivedEvent.Set(); responseArrivedCallback(requestContext, new BinaryDataBuffer(readData)); } HttpWebRequest webRequest; ManualResetEvent requestSentEvent; BinaryDataBuffer requestMsg; object requestContext; ManualResetEvent responseArrivedEvent; ResponseArrivedCallback responseArrivedCallback; } I use this code to send data back and forth to an HTTP server.

• XML Socket and Regular Socket in Flash/Flex does not send message immediately.

  - by kramer

  I am trying to build a basic RIA where my Flex application client opens an XML socket, sends the xml message "people_list" to server, and prints out the response. I have ruby at the server side and I have successfully set up the security policy stuff. The ruby xml server, successfully accepts the connections from Flex, successfully detects when they are closed and can also send messages to client. But; there is a problem... It cannot receive messages from flex client. The messages sent from flex client are queued and sent as one package when the socket is closed. Therefore, the whole wait-for-request-then-reply thing is not working... This is also -kinda- mentioned in the XMLSocket.send() document, where it is stated that the messages are sent async so; they may be delivered at any time in future. But; I need them to be synced, flushed or whatever. This is the server side code: require 'socket' require 'observer' class Network_Reader_Ops include Observable @@reader_listener_socket = UDPSocket.new @@reader_broadcast_socket = UDPSocket.new @@thread_id def initialize @@reader_broadcast_socket.setsockopt(Socket::SOL_SOCKET, Socket::SO_BROADCAST, 1) @@reader_broadcast_socket.setsockopt(Socket::SOL_SOCKET, Socket::SO_REUSEADDR, 1) @@reader_listener_socket.setsockopt(Socket::SOL_SOCKET, Socket::SO_REUSEADDR, 1) @@reader_broadcast_socket.bind('', 50050) @@reader_listener_socket.bind('', 50051) @@thread_id = Thread.start do loop do begin text, sender = @@reader_listener_socket.recvfrom_nonblock 1024 print("Knock response recived: ", text) notify_observers text rescue Errno::EAGAIN retry rescue Errno::EWOULDBLOCK retry end end end end def query @@reader_broadcast_socket.send("KNOCK KNOCK", 0, "255.255.255.255", 50050) end def stop Thread.kill @@thread_id end end class XMLSocket_Connection attr_accessor :connection_id def update (data) connection_id.write(data+"\0") end end begin # Set EOL for Flash $/ = '\x00' xml_socket = TCPServer.open('', '4444') security_policy_socket = TCPServer.open('', '843') xml_socket.setsockopt(Socket::SOL_SOCKET, Socket::SO_REUSEADDR, 1) security_policy_socket.setsockopt(Socket::SOL_SOCKET, Socket::SO_REUSEADDR, 1) a = Thread.start do network_ops = nil loop { accepted_connection = xml_socket.accept print(accepted_connection.peeraddr, " is accepted\n") while accepted_connection.gets incoming = $_.dump print("Received: ", incoming) if incoming == "<request>readers on network</request>" then network_ops = Network_Reader_Ops.new this_con = XMLSocket_Connection.new this_con.connection_id = accepted_connection network_ops.add_observer this_con network_ops.query end end if not network_ops.nil? then network_ops.delete_observer this_con network_ops.stop network_ops = nil end print(accepted_connection, " is gone\n") accepted_connection.close } end b = Thread.start do loop { accepted_connection = security_policy_socket.accept Thread.start do current_connection = accepted_connection while current_connection.gets if $_ =~ /.*policy\-file.*/i then current_connection.write("<cross-domain-policy><allow-access-from domain="*" to-ports="*" /></cross-domain-policy>\0") end end current_connection.close end } end a.join b.join rescue puts "FAILED" retry end And this is the flex/flash client side code: UPDATE: I have also tried using regular socket and calling flush() method but; the result was same. private var socket:XMLSocket = new XMLSocket(); protected function stopXMLSocket():void { socket.close(); } protected function startXMLSocket():void { socket.addEventListener(DataEvent.DATA, dataHandler); socket.connect(xmlSocketServer_address, xmlSocketServer_port); socket.send("<request>readers on network</request>"); } protected function dataHandler(event:DataEvent):void { mx.controls.Alert.show(event.data); } How do I achieve the described behaviour?

• Asynchronous callback for network in Objective-C Iphone

  - by vodkhang

  I am working with network request - response in Objective-C. There is something with asynchronous model that I don't understand. In summary, I have a view that will show my statuses from 2 social networks: Twitter and Facebook. When I clicked refresh, it will call a model manager. That model manager will call 2 service helpers to request for latest items. When 2 service helpers receive data, it will pass back to model manager and this model will add all data into a sorted array. What I don't understand here is that : when response from social networks come back, how many threads will handle the response. From my understanding about multithreading and networking (in Java), there must have 2 threads handle 2 responses and those 2 threads will execute the code to add the responses to the array. So, it can have race condition and the program can go wrong right? Is it the correct working model of iphone objective-C? Or they do it in a different way that it will never have race condition and we don't have to care about locking, synchronize? Here is my example code: ModelManager.m - (void)updateMyItems:(NSArray *)items { self.helpers = [self authenticatedHelpersForAction:NCHelperActionGetMyItems]; for (id<NCHelper> helper in self.helpers) { [helper updateMyItems:items]; // NETWORK request here } } - (void)helper:(id <NCHelper>)helper didReturnItems:(NSArray *)items { [self helperDidFinishGettingMyItems:items callback:@selector(model:didGetMyItems:)]; break; } } // some private attributes int *_currentSocialNetworkItemsCount = 0; // to count the number of items of a social network - (void)helperDidFinishGettingMyItems:(NSArray *)items { for (Item *item in items) { _currentSocialNetworkItemsCount ++; } NSLog(@"count: %d", _currentSocialNetworkItemsCount); _currentSocialNetworkItemsCount = 0; } I want to ask if there is a case that the method helperDidFinishGettingMyItems is called concurrently. That means, for example, faceboook returns 10 items, twitter returns 10 items, will the output of count will ever be larger than 10? And if there is only one single thread, how can the thread finishes parsing 1 response and jump to the other response because, IMO, thread is only executed sequently, block of code by block of code

• WCF Webservices and FaultContract - Client's receiving SoapExc insted of FaultException<TDetails>

  - by Alessandro Di Lello

  Hi All, i'm developing a WCF Webservice and consuming it within a mvc2 application. My problem is that i'm using FaultContracts on my methods with a custom FaultDetail and i'm throwing manyally the faultexception but when the client receive the exception , it receives a normal SoapException instead of my FaultException that i throwed from the service side. Here is some code: Custom Fault Detail Class: [DataContract] public class MyFaultDetails { [DataMember] public string Message { get; set; } } Operation on service contract: [OperationContract] [FaultContract(typeof(MyFaultDetails))] void ThrowException(); Implementation: public void ThrowException() { var details = new MyFaultDetails { Message = "Exception Test" }; throw new FaultException<MyFaultDetails >(details , new FaultReason(details .Message), new FaultCode("MyFault")); } Client side: try { // Obv proxy init etc.. service.ThrowException(); } catch (FaultException<MyFaultDetails> ex) { // stuff } catch (Exception ex) { // stuff } What i expect is to catch the FaultException , instead that catch is skipped and the next catch is taken with an exception of type SoapException. Am i missing something ? i red a lot of threads about using faultcontracts within wcf and what i did seems to be good. I had a look at the wsdl and xsd generated and they look fine. here's a snippet regarding this method: <wsdl:operation name="ThrowException"> <wsdl:input wsaw:Action="http://tempuri.org/IAnyJobService/ThrowException" message="tns:IAnyJobService_ThrowException_InputMessage" /> <wsdl:output wsaw:Action="http://tempuri.org/IAnyJobService/ThrowExceptionResponse" message="tns:IAnyJobService_ThrowException_OutputMessage" /> <wsdl:fault wsaw:Action="http://tempuri.org/IAnyJobService/ThrowExceptionAnyJobServiceFaultExceptionFault" name="AnyJobServiceFaultExceptionFault" message="tns:IAnyJobService_ThrowException_AnyJobServiceFaultExceptionFault_FaultMessage" /> </wsdl:operation> <wsdl:operation name="ThrowException"> <soap:operation soapAction="http://tempuri.org/IAnyJobService/ThrowException" style="document" /> <wsdl:input> <soap:body use="literal" /> </wsdl:input> <wsdl:output> <soap:body use="literal" /> </wsdl:output> <wsdl:fault name="AnyJobServiceFaultExceptionFault"> <soap:fault use="literal" name="AnyJobServiceFaultExceptionFault" namespace="" /> </wsdl:fault> </wsdl:operation> Any help ?

• CruiseControl.Net Publisher email failing to send e-mail

  - by CrimsonX

  So here's my problem: I cannot seem to be able to configure CruiseControl.NET to send out an e-mail to me when a build occurs. I copied the example from the documentation and filled it in with my own values. http://confluence.public.thoughtworks.org/display/CCNET/Email+Publisher Here's the relevant section of ccnet.config below <publishers> <merge> <files> <file>C:\Build\Temp\*.xml</file> </files> </merge> <xmllogger logDir="buildlogs" /> <statistics> <statisticList> <statistic /> </statisticList> </statistics> <email includeDetails="TRUE" mailhostUsername="user" mailhostPassword="password" useSSL="TRUE"> <from>[email protected]</from> <mailhost>mail.mycompanysmtpserver.com</mailhost> <users> <user name="MyName Lastname" group="buildmaster" address="[email protected]" /> </users> <groups> <group name="buildmaster"> <notifications> <notificationType>Always</notificationType> </notifications> </group> </groups> <modifierNotificationTypes> <NotificationType>Failed</NotificationType> <NotificationType>Fixed</NotificationType> </modifierNotificationTypes> <subjectSettings> <subject buildResult="StillBroken" value="Build is still broken for {CCNetProject}" /> </subjectSettings> </email> </publishers> I have had a successful CruiseControl.NET server configured for some time, and it successfully updates people through CCTray, but I need to add e-mail support as well. I've already looked at the relevant StackOverflow articles like this one and many more and tried my hand at googling the solution but I dont know what I could be doing wrong. The only other thing that I'd like to validate is that I can send/receive e-mails using my username/password with the SMTP server I received from IT (my mail works properly) but I just followed the steps on testing an SMTP server here and everything looks fine http://support.microsoft.com/kb/153119 Anyone have any ideas as to why I'm getting this problem, or how to troubleshoot it further?

• WCF Timeout issue - should there even be a socket connection?

  - by stiank81

  I have a .Net application which is split into a client and server side. The communication between them is handled using WCF. I'm not using the automagic service references, but instead I've built the connection manually like described in the Screencast by Miguel Castro. Summarized this means that I create a console application on the server side that holds ServiceHost objects for the different services: var myServiceHost = new System.ServiceModel.ServiceHost(typeof(MyService), new Uri("net.tcp://localhost:8002")); myServiceHost.Open(); And on the client side I have service proxies creating channels using the ChannelFactory: IMyService proxy = new ChannelFactory<IMyService>("MyServiceEndpoint").CreateChannel(); The client and server side share the service contract defined in the interface IMyService. And another advantage is that I get minimal App.config files - without all the autogenerated stuff created through the Service References. Example from client side: <?xml version="1.0"?> <configuration> <system.serviceModel> <client> <endpoint address="net.tcp://localhost:8002/MyEndpoint" binding="netTcpBinding" contract="IMyService" name="MyServiceEndpoint"/> </client> </system.serviceModel> </configuration> So - to my problem. I create the proxy once, and it holds a channel all the way through the application. However, if I leave the application without use for a few minutes the channel has timed out, and I get the following exception: The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '00:00:59.9979998'. How do I prevent this? I'm assuming I need to specify a higher timeout in my configuration? But I don't want it to ever time out. But on the other hand - I don't want a socket connection! Do I need one? Thought I could go connection less with WCF... What's the permanent solution and best practice on solving this? Set timeout to "never".. Create a new channel for each request? I'm assuming there is some overhead creating the channel?.. Increase the timeout to e.g. 5minutes and create new channel if the connection did timeout? Make it connection less somehow? (Without the overhead of creating channels..) Something else...

• Unity and Object Creation

  - by William

  I am using unity as my IoC container. I am trying to implement a type of IProviderRepository. The concrete implementation has a constructor that accepts a type of IRepository. When I remove the constructor parameter from the concrete implementation everything works fine. I am sure the container is wired correctly. When I try to create the concrete object with the constructor I receive the following error: "The current build operation (build key Build Key[EMRGen.Infrastructure.Data.IRepository1[EMRGen.Model.Provider.Provider], null]) failed: The current type, EMRGen.Infrastructure.Data.IRepository1[EMRGen.Model.Provider.Provider], is an interface and cannot be constructed. Are you missing a type mapping? (Strategy type BuildPlanStrategy, index 3)". Is it possible to achieve the above mention functionality with Unity? Namely have Unity infer a concrete type from the Interface and also inject the constructor of the concrete type with the appropriate concrete object based on constructor parameters. Below is sample of my types defined in Unity and a skeleton class listing for what I want to achieve. IProviderRepository is implemented by ProviderRepository which has a constructor that expects a type of IRepository. <typeAlias alias="ProviderRepositoryInterface" type="EMRGen.Model.Provider.IProviderRepository, EMRGen.Model" /> <typeAlias alias="ProviderRepositoryConcrete" type="EMRGen.Infrastructure.Repositories.Providers.ProviderRepository, EMRGen.Infrastructure.Repositories" /> <typeAlias alias="ProviderGenericRepositoryInterface" type="EMRGen.Infrastructure.Data.IRepository`1[[EMRGen.Model.Provider.IProvider, EMRGen.Model]], EMRGen.Infrastructure" /> <typeAlias alias="ProviderGenericRepositoryConcrete" type="EMRGen.Infrastructure.Repositories.EntityFramework.ApplicationRepository`1[[EMRGen.Model.Provider.Provider, EMRGen.Model]], EMRGen.Infrastructure.Repositories" /> <!-- Provider Mapping--> <typeAlias alias="ProviderInterface" type="EMRGen.Model.Provider.IProvider, EMRGen.Model" /> <typeAlias alias="ProviderConcrete" type="EMRGen.Model.Provider.Doctor, EMRGen.Model" /> //Illustrate the call being made inside my class public class PrescriptionService { PrescriptionService() { IUnityContainer uc = UnitySingleton.Instance.Container; UnityServiceLocator unityServiceLocator = new UnityServiceLocator(uc); ServiceLocator.SetLocatorProvider(() => unityServiceLocator); IProviderRepository pRepository = ServiceLocator.Current.GetInstance<IProviderRepository>(); } } public class GenericRepository<IProvider> : IRepository<IProvider> { } public class ProviderRepository : IProviderRepository { private IRepository<IProvider> _genericProviderRepository; //Explict public default constructor public ProviderRepository(IRepository<IProvider> genericProviderRepository) { _genericProviderRepository = genericProviderRepository; } }

• C#.NET Socket Programming: Connecting to remote computers.

  - by Gio Borje

  I have a typical server in my end and a friend using a client to connect to my IP/Port and he consistently receives the exception: "A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond {MY_IP}:{MY_PORT}"—You don't need to know my IP. The client and server, however, work fine on the loopback address (127.0.0.1). I also do not have any firewall nor is windows firewall active.

• Exception using SQLiteDataReader

  - by galford13x

  I'm making a Custom SQLite Wrapper. This is meant to allow a presistent connection to a database. However, I receive an exception when calling this function twice. public Boolean DatabaseConnected(string databasePath) { bool exists = false; if (ConnectionOpen()) { this.Command.CommandText = string.Format(DATABASE_QUERY); using (reader = this.Command.ExecuteReader()) { while (reader.Read()) { if (string.Compare(reader[FILE_NAME_COL_HEADER].ToString(), databasePath, true) == 0) { exists = true; break; } } reader.Close(); } } return exists; } I use the above function to check if the database is currently open before executing a command or trying to open a database.

• Limit for Google calendar SMS notification per day

  - by pit777

  What is the limit for Google calendar SMS notification per day? How to detect I reached sms limit? Google write only this: http://www.google.com/support/calendar/bin/answer.py?hl=en&answer=36589 You might have reached the limit for SMS notifications. There is a limit to the number of SMS notifications you can receive each day. This limit shouldn't affect most users, but it's something to keep in mind if you've scheduled a large number of events and are no longer receiving SMS notifications. I created sms reminder based on google calendar api(apps-script), but I think now I reached the daily limit for SMS notifications... but google not informed what is exactly amount of sms limit restriction :/ function emailNotification() { // POWIADOMIENIA SMS O NOWEJ POCZCIE var calendarID = "[email protected]"; // id kalendarza o nazwie „sms4email” var gmailLabelTODO = "autoscriptslabels/sms"; // etykieta „AutoScriptsLabels/SMS” var gmailLabelDONE = "done/_sms"; // etykieta „DONE/_SMS” var calendarEventDescription = "this-is-sms_notification-mark"; // etykieta utworzonego zdarzenia, dzieki której mozna bedzie je znalezc podczas kasowania var calendar = CalendarApp.getCalendarById(calendarID); // otwieramy kalendarz var threads = GmailApp.getUserLabelByName(gmailLabelTODO).getThreads(); // zmienna przechowujaca kolekcje lancuszków z etykieta TODO var now = new Date(); if(threads == 0) return; // zaprzestanie wykonywania, jezeli brak nowych lancuszków for(i in threads) // tworzymy zdarzenia { var title = threads[i].getFirstMessageSubject(); // tytul emaila var startDate = new Date(now.getTime()+120000); var endDate = new Date(now.getTime()+120000); var messages = threads[i].getMessages(); var senderEmail = messages[0].getFrom(); // nadawca emaila var advancedArgs = {location:senderEmail, description:calendarEventDescription}; calendar.createEvent(title, startDate, endDate, advancedArgs); } Utilities.sleep(1000); GmailApp.getUserLabelByName(gmailLabelDONE).addToThreads(threads); // dodawanie etykiety DONE Utilities.sleep(1000); GmailApp.getUserLabelByName(gmailLabelTODO).removeFromThreads(threads); // usuwanie etykiety TODO Utilities.sleep(120000); // czekamy az kalendarz wysle SMS var TodaysEvents = calendar.getEventsForDay(now); for (i in TodaysEvents) // wyszukiwanie wedlug zdarzenia i kasowanie po wyslaniu { if (TodaysEvents[i].getDescription()==calendarEventDescription) TodaysEvents[i].deleteEvent(); } }

• SIMPLE OpenSSL RSA Encryption in C/C++ is causing me headaches

  - by Josh

  Hey guys, I'm having some trouble figuring out how to do this. Basically I just want a client and server to be able to send each other encrypted messages. This is going to be incredibly insecure because I'm trying to figure this all out so I might as well start at the ground floor. So far I've got all the keys working but encryption/decryption is giving me hell. I'll start by saying I am using C++ but most of these functions require C strings so whatever I'm doing may be causing problems. Note that on the client side I receive the following error in regards to decryption. error:04065072:rsa routines:RSA_EAY_PRIVATE_DECRYPT:padding check failed I don't really understand how padding works so I don't know how to fix it. Anywho here are the relevant variables on each side followed by the code. Client: RSA *myKey; // Loaded with private key // The below will hold the decrypted message unsigned char* decrypted = (unsigned char*) malloc(RSA_size(myKey)); /* The below holds the encrypted string received over the network. Originally held in a C-string but C strings never work for me and scare me so I put it in a C++ string */ string encrypted; // The reinterpret_cast line was to get rid of an error message. // Maybe the cause of one of my problems? if(RSA_private_decrypt(sizeof(encrypted.c_str()), reinterpret_cast<const unsigned char*>(encrypted.c_str()), decrypted, myKey, RSA_PKCS1_OAEP_PADDING)==-1) { cout << "Private decryption failed" << endl; ERR_error_string(ERR_peek_last_error(), errBuf); printf("Error: %s\n", errBuf); free(decrypted); exit(1); } Server: RSA *pkey; // Holds the client's public key string key; // Holds a session key I want to encrypt and send //The below will hold the encrypted message unsigned char *encrypted = (unsigned char*)malloc(RSA_size(pkey)); // The reinterpret_cast line was to get rid of an error message. // Maybe the cause of one of my problems? if(RSA_public_encrypt(sizeof(key.c_str()), reinterpret_cast<const unsigned char*>(key.c_str()), encrypted, pkey, RSA_PKCS1_OAEP_PADDING)==-1) { cout << "Public encryption failed" << endl; ERR_error_string(ERR_peek_last_error(), errBuf); printf("Error: %s\n", errBuf); free(encrypted); exit(1); } Let me once again state, in case I didn't before, that I know my code sucks but I'm just trying to establish a framework for understanding this. I'm sorry if this offends you veteran coders. Thanks in advance for any help you guys can provide!

• getExtra from Intent launched from a pendingIntent

  - by spagi

  Hi. I am trying to make some alarms after the user selects something with a time from a list and create a notification for it at the given time. My problem is that the "showname" that a putExtra on my Intent cant be received at the broadcast receiver. It always get null value. This is the way I do it for most of my intents but I think this time maybe because of the pendingIntent or the broadcastReceiver something need to be done differentelly. Thank you The function that sends the Intent through the pending intent public void setAlarm(String showname,String time) { String[] hourminute=time.split(":"); String hour = hourminute[0]; String minute = hourminute[1]; Calendar rightNow = Calendar.getInstance(); rightNow.set(Calendar.HOUR_OF_DAY, Integer.parseInt(hour)); rightNow.set(Calendar.MINUTE, Integer.parseInt(minute)); rightNow.set(Calendar.SECOND, 0); long t=rightNow.getTimeInMillis(); long t1=System.currentTimeMillis(); try { Intent intent = new Intent(this, alarmreceiver.class); Bundle c = new Bundle(); c.putString("showname", showname);//This is the value I want to pass intent.putExtras(c); PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 12345, intent, 0); AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE); alarmManager.set(AlarmManager.RTC_WAKEUP, rightNow.getTimeInMillis(),pendingIntent); //Log.e("ALARM", "time of millis: "+System.currentTimeMillis()); Toast.makeText(this, "Alarm set", Toast.LENGTH_LONG).show(); } catch (Exception e) { Log.e("ALARM", "ERROR IN CODE:"+e.toString()); } } And this is the receiving end public class alarmreceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { // Toast.makeText(context, "Alarm worked.", Toast.LENGTH_LONG).show(); Bundle b = intent.getExtras(); String showname=b.getString("showname");//This is where I suppose to receive it but its null NotificationManager manger = (NotificationManager) context .getSystemService(context.NOTIFICATION_SERVICE); Notification notification = new Notification(R.drawable.icon, "TVGuide ?pe???µ?s?", System.currentTimeMillis()); PendingIntent contentIntent = PendingIntent.getActivity(context, 0, new Intent(context, tvguide.class), 0); notification.setLatestEventInfo(context, "?? ?????aµµa ?e????se", showname, contentIntent); notification.flags = Notification.FLAG_ONLY_ALERT_ONCE; notification.sound = Uri.parse("file:///sdcard/dominating.mp3"); notification.vibrate = new long[]{100, 250, 100, 500}; manger.notify(1, notification); } }

• log4net not logging with a mixture of .net 1.1 and .net 3.5

  - by Jim P

  Hi All, I have an iis server on a windows 2003 production machine that will not log using log4net in the .net3.5 web application. Log4net works fine in the 1.1 apps using log4net version 1.2.9.0 and but not the 3.5 web app. The logging works fine in a development and staging environment but not in production. It does not error and I receive no events logged in the event viewer and don't know where to look next. I have tried both versions of log4net (1.2.9.0 and 1.2.10.0) and both work in development and staging but not in production. For testing purposes I have created just a single page application that just echos back the time when the page is hit and also is supposed to log to my logfile using log4net. Here is my web.config file: <configSections> <!-- LOG4NET Configuration --> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" requirePermission="false" /> </configSections> <log4net debug="true"> <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender"> <param name="File" value="D:\DIF\Logs\TestApp\TestApp_"/> <param name="AppendToFile" value="true"/> <param name="RollingStyle" value="Date"/> <param name="DatePattern" value="yyyyMMdd\.\l\o\g"/> <param name="StaticLogFileName" value="false"/> <layout type="log4net.Layout.PatternLayout"> <param name="ConversionPattern" value="%date{HH:mm:ss} %C::%M [%-5level] - %message%newline"/> </layout> </appender> <root> <level value="ALL"/> <appender-ref ref="RollingFileAppender"/> </root> </log4net> Here is my log4net initialization: // Logging for the application private static ILog mlog = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType); protected void Application_Start(object sender, EventArgs e) { try { // Start the configuration of the Logging XmlConfigurator.Configure(); mlog.Info("Started logging for the TestApp Application."); } catch (Exception ex) { throw; } } Any help would be greatly appreciated.

• Asynchronous sockets in C#

  - by IVlad

  I'm confused about the correct way of using asynchronous socket methods in C#. I will refer to these two articles to explain things and ask my questions: MSDN article on asynchronous client sockets and devarticles.com article on socket programming. My question is about the BeginReceive() method. The MSDN article uses these two functions to handle receiving data: private static void Receive(Socket client) { try { // Create the state object. StateObject state = new StateObject(); state.workSocket = client; // Begin receiving the data from the remote device. client.BeginReceive( state.buffer, 0, StateObject.BufferSize, 0, new AsyncCallback(ReceiveCallback), state); } catch (Exception e) { Console.WriteLine(e.ToString()); } } private static void ReceiveCallback( IAsyncResult ar ) { try { // Retrieve the state object and the client socket // from the asynchronous state object. StateObject state = (StateObject) ar.AsyncState; Socket client = state.workSocket; // Read data from the remote device. int bytesRead = client.EndReceive(ar); if (bytesRead > 0) { // There might be more data, so store the data received so far. state.sb.Append(Encoding.ASCII.GetString(state.buffer,0,bytesRead)); // Get the rest of the data. client.BeginReceive(state.buffer,0,StateObject.BufferSize,0, new AsyncCallback(ReceiveCallback), state); } else { // All the data has arrived; put it in response. if (state.sb.Length > 1) { response = state.sb.ToString(); } // Signal that all bytes have been received. receiveDone.Set(); } } catch (Exception e) { Console.WriteLine(e.ToString()); } } While the devarticles.com tutorial passes null for the last parameter of the BeginReceive method, and goes on to explain that the last parameter is useful when we're dealing with multiple sockets. Now my questions are: What is the point of passing a state to the BeginReceive method if we're only working with a single socket? Is it to avoid using a class field? It seems like there's little point in doing it, but maybe I'm missing something. How can the state parameter help when dealing with multiple sockets? If I'm calling client.BeginReceive(...), won't all the data be read from the client socket? The devarticles.com tutorial makes it sound like in this call: m_asynResult = m_socClient.BeginReceive (theSocPkt.dataBuffer,0,theSocPkt.dataBuffer.Length, SocketFlags.None,pfnCallBack,theSocPkt); Data will be read from the theSocPkt.thisSocket socket, instead of from the m_socClient socket. In their example the two are one and the same, but what happens if that is not the case? I just don't really see where that last argument is useful or at least how it helps with multiple sockets. If I have multiple sockets, I still need to call BeginReceive on each of them, right?

• Safari/Chrome problem with ajaxsubmit?

  - by Jan

  Hi I'm currently having some weird issues with ajaxsubmit (http://jquery.malsup.com/form/#ajaxSubmit), which I'm currently using in a project. I have a flow where I need to open a form into a modal window. I'm using fancybox for that and it works like a charm. When the form has been forced to open in the fancybox window there can happen two things. 1) If the user who is about to submit the form is logged in she should see a confirmation in the modal box, that her input was succesfully submitted 2)If the user is not logged in there should be loaded a login form once she hits the submit button 2.1) When the user has logged in she should receive a confirmation in the modal box. This is also working like a charm in Firefox, IE8 and IE7 but not in Safari or Chrome. The weird part is that it seems like safari and chrome are completely ignoring my ajaxsubmit form. To force the first form to be opened I use the follwoing script - this part is working in both Safari and Chrome. $(".klikEnPrisForm").ajaxForm({ success: function(data){ $.fancybox({'content':data}); } }); My ajaxsubmit form scrip looks like this var options = { url: '/?altTemplate=XmlProxyKlikEnPris', dataType: 'xml', data: $(this).serializeArray(), success: function(data) { if ($(data).find('loggetind').text() == 'true') { $("#klikenpris").hide(); $('<div id="fancybox-inner-klik"></div>').appendTo('#fancybox-inner'); $('#fancybox-inner-klik').load('/KlikEnPrisAccept?tilKvittering=1&sagsno=' + $(data).find('sagsnummer').text() + '&pris=' + $(data).find('pris').text() + '&klik-comment=' + $(data).find('kommentar').text() + '&klik-telefon=' + $(data).find('tlf').text() + '&klik-maeglerkontakt=' + $(data).find('maakontakte').text()).stop(true, true); } else { $("#klikenpris").hide(); $("#fancybox-wrap").css({ 'width': '480px', 'height': '220px' }); $("#fancybox-inner").css({ 'width': '460px', 'height': '220px' }); $('<div id="fancybox-inner-klik"></div>').appendTo('#fancybox-inner'); $('#fancybox-inner-klik').load('/login.aspx?loginklikpris=0&klikpris=1&sagsno=' + $(data).find('sagsnummer').text() + '&pris=' + $(data).find('pris').text() + '&klik-comment=' + $(data).find('kommentar').text() + '&klik-telefon=' + $(data).find('tlf').text() + '&klik-maeglerkontakt=' + $(data).find('maakontakte').text()).stop(true, true); } } }; // bind to the form's submit event $('#klikenprisform').submit(function() { // inside event callbacks 'this' is the DOM element so we first // wrap it in a jQuery object and then invoke ajaxSubmit $(this).ajaxSubmit(options); // !!! Important !!! // always return false to prevent standard browser submit and page navigation return false; }); I have tried inserting an alert in the succes callback function but it's never being called it seems. It seems like the default action is not being overruled by the link written in the "url" in ajaxsubmit. I'm really puzzled about this, since it's working nicely in other browsers and I'm completely lost on how I should approach the debugging in safari/chrome. I hope all the above makes sense and I'm looking forward to hear any suggestions. Cheers!

• Asp.net MVC VirtualPathProvider views parse error

  - by madcapnmckay

  Hi, I am working on a plugin system for Asp.net MVC 2. I have a dll containing controllers and views as embedded resources. I scan the plugin dlls for controller using StructureMap and I then can pull them out and instantiate them when requested. This works fine. I then have a VirtualPathProvider which I adapted from this post public class AssemblyResourceProvider : VirtualPathProvider { protected virtual string WidgetDirectory { get { return "~/bin"; } } private bool IsAppResourcePath(string virtualPath) { var checkPath = VirtualPathUtility.ToAppRelative(virtualPath); return checkPath.StartsWith(WidgetDirectory, StringComparison.InvariantCultureIgnoreCase); } public override bool FileExists(string virtualPath) { return (IsAppResourcePath(virtualPath) || base.FileExists(virtualPath)); } public override VirtualFile GetFile(string virtualPath) { return IsAppResourcePath(virtualPath) ? new AssemblyResourceVirtualFile(virtualPath) : base.GetFile(virtualPath); } public override CacheDependency GetCacheDependency(string virtualPath, IEnumerable virtualPathDependencies, DateTime utcStart) { return IsAppResourcePath(virtualPath) ? null : base.GetCacheDependency(virtualPath, virtualPathDependencies, utcStart); } } internal class AssemblyResourceVirtualFile : VirtualFile { private readonly string path; public AssemblyResourceVirtualFile(string virtualPath) : base(virtualPath) { path = VirtualPathUtility.ToAppRelative(virtualPath); } public override Stream Open() { var parts = path.Split('/'); var resourceName = Path.GetFileName(path); var apath = HttpContext.Current.Server.MapPath(Path.GetDirectoryName(path)); var assembly = Assembly.LoadFile(apath); return assembly != null ? assembly.GetManifestResourceStream(assembly.GetManifestResourceNames().SingleOrDefault(s => string.Compare(s, resourceName, true) == 0)) : null; } } The VPP seems to be working fine also. The view is found and is pulled out into a stream. I then receive a parse error Could not load type 'System.Web.Mvc.ViewUserControl<dynamic>'. which I can't find mentioned in any previous example of pluggable views. Why would my view not compile at this stage? Thanks for any help, Ian EDIT: Getting closer to an answer but not quite clear why things aren't compiling. Based on the comments I checked the versions and everything is in V2, I believe dynamic was brought in at V2 so this is fine. I don't even have V3 installed so it can't be that. I have however got the view to render, if I remove the <dynamic> altogether. So a VPP works but only if the view is not strongly typed or dynamic This makes sense for the strongly typed scenario as the type is in the dynamically loaded dll so the viewengine will not be aware of it, even though the dll is in the bin. Is there a way to load types at app start? Considering having a go with MEF instead of my bespoke Structuremap solution. What do you think?

• Ajax call to WCF service returns 12031 ERROR_INTERNET_CONNECTION_RESET on new endpoint

  I have extended a WCF service with new functionality in the form of a second service contract. The service.cs now implements both contracts.

• Sockets server design advice

  - by Rob

  We are writing a socket server in c# and need some advice on the design. Background: Clients (from mobile devices) connect to our server app and we leave their socket open so we can send data back down to them whenever we need to. The amount of data varies but we generally send/receive data from each client every few seconds, so it's quite intensive. The amount of simultaneous connections can range from 50-500 (and more in the future). We have already written a server app using async sockets and it works, however we've come across some stumbling blocks and we need to make sure that what we're doing is correct. We have a collection which holds our client states (we have no socket/connection pool at the moment, should we?). Each time a client connects we create a socket and then wait for them to send us some data and in receiveCallBack we add their clientstate object to our connections dictionary (once we have verified who they are). When a client object then signs off we shutdown their socket and then close it as well as remove them from our collection of clients dictionary. Presumably everything happens in the right order, everything works as expected. However, almost everyday it stops accepting connections, or so we think, either that or it connects but doesn't actually do anything past that and we can't work out why it's just stopping. There are few things that we'r'e unsure about 1) Should we be creating some kind of connection pool as opposed to just a dictionary of client sockets 2) What happens to the sockets that connect but then don't get added to our dictionary, they just linger around in memory doing nothing, should we create ANOTHER dictionary that holds the sockets as soon as they are created? 3) What's the best way of finding if clients are no longer connected? We've read some many methods but we're not sure of the best one to use, send data or read data, if so how? 4) If we loop through the connections dictonary to check for disposed clients, should we be locking the dictionary, if so how does this affect other clients objects trying to use it at the same time, will it throw an error or just wait? 5) We often get disposedSocketException within ReceiveCallBack method at random times, does this mean we are safe to remove that socket from the collection? We can't seem to find any production type examples which show any of this working. Any advice would be greatly received

• Does oneway declaration in Android .aidl guarantee that method will be called in a separate thread?

  - by Dan Menes

  I am designing a framework for a client/server application for Android phones. I am fairly new to both Java and Android (but not new to programming in general, or threaded programming in particular). Sometimes my server and client will be in the same process, and sometimes they will be in different processes, depending on the exact use case. The client and server interfaces look something like the following: IServer.aidl: package com.my.application; interface IServer { /** * Register client callback object */ void registerCallback( in IClient callbackObject ); /** * Do something and report back */ void doSomething( in String what ); . . . } IClient.aidl: package com.my.application; oneway interface IClient { /** * Receive an answer */ void reportBack( in String answer ); . . . } Now here is where it gets interesting. I can foresee use cases where the client calls IServer.doSomething(), which in turn calls IClient.reportBack(), and on the basis of what is reported back, IClient.reportBack() needs to issue another call to IClient.doSomething(). The issue here is that IServer.doSomething() will not, in general, be reentrant. That's OK, as long as IClient.reportBack() is always invoked in a new thread. In that case, I can make sure that the implementation of IServer.doSomething() is always synchronized appropriately so that the call from the new thread blocks until the first call returns. If everything works the way I think it does, then by declaring the IClient interface as oneway, I guarantee this to be the case. At least, I can't think of any way that the call from IServer.doSomething() to IClient.reportBack() can return immediately (what oneway is supposed to ensure), yet IClient.reportBack still be able to reinvoke IServer.doSomething recursively in the same thread. Either a new thread in IServer must be started, or else the old IServer thread can be re-used for the inner call to IServer.doSomething(), but only after the outer call to IServer.doSomething() has returned. So my question is, does everything work the way I think it does? The Android documentation hardly mentions oneway interfaces.

• Java JMS Messaging

  - by London

  Hello, I have a working example of sending message to server and server receiving it via qpid messaging. Here is simple hello world to send to server : http://pastebin.com/M7mSECJn And here is server which receives requests and sends response(the current client doesn't receive response) : http://pastebin.com/2mEeuzrV Here is my property file : http://pastebin.com/TLEFdpXG They all work perfectly, I can see the messages in the qpid queue via Qpid JMX management console. These examples are downloaded from https://svn.apache.org/repos/asf/qpid/trunk/qpid/java/client/example (someone may need it also). I've done Jboss messaging using spring before, but I can't manage to do the same with qpid. With jboss inside applicationsContext I had beans jndiTemplate, conectionFactory, destinationQueue, and jmscontainer like this : <!-- Queue configuration --> <bean id="jndiTemplate" class="org.springframework.jndi.JndiTemplate"> <property name="environment"> <props> <prop key="java.naming.factory.initial">org.jnp.interfaces.NamingContextFactory</prop> <prop key="java.naming.provider.url">jnp://localhost:1099</prop> <prop key="java.naming.factory.url.pkgs">org.jboss.naming:org.jnp.interfaces</prop> <prop key="java.naming.security.principal">admin</prop> <prop key="java.naming.security.credentials">admin</prop> </props> </property> </bean> <bean id="connectionFactory" class="org.springframework.jndi.JndiObjectFactoryBean"> <property name="jndiTemplate" ref="jndiTemplate" /> <property name="jndiName" value="ConnectionFactory" /> </bean> <bean id="queueDestination" class="org.springframework.jndi.JndiObjectFactoryBean"> <property name="jndiTemplate" ref="jndiTemplate" /> <property name="jndiName"> <value>queue/testQueue</value> </property> </bean> <bean id="jmsContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer"> <property name="connectionFactory" ref="connectionFactory" /> <property name="destination" ref="queueDestination" /> <property name="messageListener" ref="listener" /> </bean> and of course sender and listener : Now I'd like to rewrite this qpid example using spring context logic. Can anyone help me?

• Dynamic Overlays slowing down Google Maps (Android 2.1) on Nexus One

  - by Soumya Simanta

  Hi, I'm trying to create a dynamic ItemizedOverylay (please see the code below) on Google Maps (Android 2.1) on a Nexus One. In my Activity (that extends MapActivity) I'm creating a data thread that is receiving data from the network. A 'handler' is used to communicate the data from the receiving thread to map activity. This data contains the locations (lat, lon) of the markers that I want to overlay on my map. The location of each marker is dynamic (i.e., it changes every time I receive new data from the network.) refreshItems(ArrayList<OverlayItem> newItems) method in invoked inside the handleMessage() of the handler. There are around 11 markers in the ArrayList that is passed to refreshItems I can see the markers overlayed on the map. However, I've two issues: The old markers are not removed from the map. After a while I see a trail of markers. The map doesn't respond to any touch commands. I cannot move the map or zoom in or zoom out. After a while I see a system warning that my app is not responding message. Any idea what's wrong here ? Thanks. public class MyItemizedOverlay extends ItemizedOverlay { private ArrayList<OverlayItem> overlayItems; public CoTItemizedOverlay(Drawable defaultMarker) { super(boundCenter(defaultMarker)); overlayItems = new ArrayList<OverlayItem>(); populate(); } public void addNewItem(GeoPoint location, String markerText, String snippet) { overlayItems.add(new OverlayItem(location, markerText, snippet)); populate(); } public void removeItem(int index) { overlayItems.remove(index); populate(); } public void refreshItems(ArrayList<OverlayItem> newItems) { // remove all existing items for (int i = 0; i < cotoverlayItems.size(); i++) { overlayItems.remove(i); } // copy all the times if (newItems != null && cotoverlayItems.size() == 0) { overlayItems.addAll(newItems); } populate(); } @Override protected OverlayItem createItem(int index) { return overlayItems.get(index); } @Override public int size() { return overlayItems.size(); } }

• Minimum permission required to access Site Columns page and edit site columns

  - by ParanoidMike

  We've started to adopt SharePoint 2010, and are starting to manually migrate content from SharePoint 2007 sites to new sites we're rebuilding from scratch in SP2010. One of the things we previously had supported was to delegate responsibility for managing some of our site columns to a member of the team. The team member is not familiar with SharePoint internals, and doesn't want the responsibility of full permissions to the site and all its objects. We're now trying to figure out what the minimum permission is that we need to grant our team member, so they can continue to edit (& propagate) the content of the site columns we've defined. Permissions he currently has (which are obviously insufficient): Site permissions (according to _layouts/user.aspx): Read, Contribute, Manage Lists Permissions for specific objects in the site (according to _layouts/people.aspxMembershipGroupId=xxx, then choosing Settings, View Group Permissions): server/sites/[sitename]: Contribute server/sites/[sitename]/Lists/[a list with columns that inherit from site columns]: "Contribute No Delete" Note: the "Contribute No Delete" permission is a custom permission I designed by copying the SharePoint-native "Contribute" permission set and deselecting the Delete permission. The "Manage Lists" permission is a custom permission I designed that includes the following specific permissions: (List Permissions) Manage Lists, View Items; (Site Permissions) View Pages, Open. Operations that are throwing access denied errors: _layouts/mngfield.aspx: SharePoint returns the "Error: Access Denied" dialog, and provides three clickable options: "Sign in as a different user", "Request access", and "Go back to site" _layouts/fldedit.aspx?field=Level%5Fx0020%5F3 [one of the site columns we've defined]: can load the page and type in changes to the textboxes "...but when I press OK (save changes) I get the same message above." When our team member clicks the "Request access" link, the email I receive sends me to a page that recommends that I grant the user membership in the "[sitename] Users" group - of which he's already a member. So while SP2010 tries to request access, it doesn't actually direct me to either (a) a valid group that has the correct permissions or (b) the specific object to which I need to grant our team member access. Also note: on the SP2007 (MOSS) site (where our team member was successful in managing Site Column edits), they had dozens of additional permissions throughout the site that we do not wish to blindly re-allocate in SP2010 until we know they're necessary. Any help anyone can provide would be greatly appreciated.
