  • Usage of closures with multiple arguments in swift

    - by Nilzone-
    This question is largely based on this one: Link The main difference being that I want to pass in arguments to the closure as well. Say I have something like this: func someFunctionThatTakesAClosure(completionClosure: (venues: Dictionary<String, AnyObject>, error: NSError) -> ()) { // function body goes here var error: NSError? let responseDictionary: Dictionary<String, AnyObject> = ["test" : "test2"] completionClosure(venues: responseDictionary, error: error!) } No error here. But when I call this function in my main view controller I have tried several ways but all of the result in different errors: venueService.someFunctionThatTakesAClosure(completionClosure(venues: Dictionary<String, AnyObject>, error: NSError){ }) or like this: venueService.someFunctionThatTakesAClosure((venues: Dictionary<String, AnyObject>, error: NSError){ }) or even like this: venueService.someFunctionThatTakesAClosure(completionClosure: (venues: Dictionary<String, AnyObject>, error: NSError) -> (){ }); I'm probably just way tired, but any help would be greatly appreciated!

  • DNS Server (2008 r2) MMC The server DC01 could not be contacted. The error was: Access was denied

    - by Silviu-Ionut Radu
    I've just migrated the AD with the whole nine yards, FSMO, PDC, RID, Schema, etc, from an SBS 2003 to a Win 2008 R2 Std. I have managed to have no error in the dcdiag before I demoted the SBS 2003 from the AD, fsmocheck, conectivity, advertising, dns, etc. The SBS 2003 demoted successfully. After this step I have restarted both, the old SBS and the new Win 2008 r2. After restart the new DC (which is the GC) started with an Access denied to the DNS Server MMC, actually it is looking like I would try to connect to the 2008 r2 DNS server from an older server console I can NOT manage DNS server through MMC nor through dnscmd (Command failed: ERROR_ACCESS_DENIED 5 0x5) I cannot even use the Action Option from the DNS Server MMC because all the options are DISABLED but for "Launch nslookup". I've made a lot of research on the internet but no luck, yet. So I come to ask for help. Thank you very much.

  • Can I create an SSH user which can access only certain directory?

    - by RiMMER
    I have a Virtual Private Server which I can connect to using SSH with my root account, being able to execute any linux command and access all the disk area, obviously. I would like to create another user account, which would be able to access this server using SSH too, but only to a certain directory, for example /var/www/example.com/ For example, imagine this user has a HUGE error.log file (500 MB) located in /var/www/example.com/logs/error.log When accessing this file using FTP, this user needs to download 500 MB to view the last lines of the log, but I'd like him to be able to execute something like this: tail error.log Therefore I need him to be able to access the server using SSH, but I don't want to grant him access to all server areas. How can I do this?

  • Database error when deleting entry in my rails app.

    - by Danny McClelland
    Hi Everyone...again! I have almost everything in my Rails app working, with the exception of detroying entries. I can destroy entries for companies but not kases and people. The following error show when trying to do so: SQLite3::SQLException: no such column: kases_people.kase_id: SELECT * FROM "kases" INNER JOIN "kases_people" ON "kases".id = "kases_people".kase_id WHERE ("kases_people".person_id = 5 ) I suspect this is an error with the party model for the has_many :through associations that I dont fully understand. You can find an up to date version of the app at www.github.com/dannyweb/surveycontrol Thanks, Danny

  • Can "\Device\NamedPipe\\Win32Pipes" handles cause "Too many open files" error?

    - by Igor Oks
    Continuing from this question: When I am trying to do fopen on Windows, I get a "Too many open files" error. I tried to analyze, how many open files I have, and seems like not too much. But when I executed Process Explorer, I noticed that I have many open handles with similar names: "\Device\NamedPipe\Win32Pipes.00000590.000000e2", "\Device\NamedPipe\Win32Pipes.00000590.000000e3", etc. I see that the number of these handles is exactly equal to the number of the iterations that my program executed, before it returned "Too many open files" and stopped. I am looking for an answer, what are these handles, and could they actually cause the "Too many open files" error? In my program I am loading files from remote drive, and I am creating TCP/IP connections. Could one of these operations create these handles?

  • How to view status of software RAID 1 resynching?

    - by tputkonen
    I have two 500 GB disks and yesterday I mirrored first drive to the second one using software RAID 1. PC has now been on for 30 hours. Both disks say "Resynching", but there is no progress indicator. In addition, there is a small yellow exclamation mark on both disks. My questions are: How long could the synch take for 500 GB drive with about 150 GB of data? PC has 4 GBs of RAM and AMD dual core 4000+ Is there a way to monitor status of the synching? How can I check what the exclamation mark means?

  • "Verifying DMI Pool" hang caused by raid array..

    - by Ling
    Hi Experts, I have a problem, I obtained a new server with 4 hard drives (2 500 gig, 2 two TB), and an adeptec RAID card. I arranged them in two arrays with RAID 1 (500 gigs together as primary and the 2 TB drives for lots of data). When both arrays are configured, the server hangs while booting at message "Verifying DMI Pool", however if I remove the second array from the configuration the server boots fine. I have checked they are both on different channels, I have disabled all other peripherals from the boot menu and ensured the hard drive is #1. I have booted into the linux rescue mode and checked that it is reading both arrays fine. What else could be causing these problems? Thanks

  • DataBinding and ErrorProvider - How to provide custom error messages?

    - by BeowulfOF
    We use BusinessObjects, implementing IDataErrorInfo and IEditableObject. BindingLists with those Objects are added to BindingSources, those are used to bind UserControls and DataGrids on the forms (WinForms). The BindingSource is additionally set as DataSource to the ErrorProvider of the form. We do use currently TextBoxes for Properties of Type int and short. They are validated inside the BusinessObjects with custom validation, like min/max values, etc. That works fine, since error message form our custom validations show up nicely next to the TextBox. However, if the input is greater than the value of an int (e.g. "9999999999") the BindingSource doesn't even try to enter that Value into the BusinesObject but instead gives the errormessage to the errorprovider like "The value for Int32 was too big.". We do not want to bother our users with "Int32" but want a custom errormessage for that. It is nice, that the BindingSource does provide this feature, but is it possible to provide custom error messages for this?

  • How do I fix "Setup did not find any hard disk drives installed in your computer" error during Win X

    - by CT
    I just bought a nettop. It came with WinXP Home. I first installed Win 7 on it. I wasn't that happy with the performance so I decided to go back to XP. I am using an external dvd drive and a Win XP Pro disc. I boot from the dvd drive and during the install get this error: Setup did not find any hard disk drives installed in your computer. Make sure any hard disk drives are powered on and properly connected to your computer, and that any disk-related hardware configuration is correct. This may involve running a manufacturer-supplied diagnostic or setup program. Setup cannot continue. To quit Setup, press F3.

  • What is the scope of TRANSACTION in Sql server

    - by Shantanu Gupta
    I was creating a stored procedure and i got stuck in the writing methodology of me and my collegue. I am using SQL Server 2005 I was writing Stored procedure like this BEGIN TRAN BEGIN TRY INSERT INTO Tags.tblTopic (Topic, TopicCode, Description) VALUES(@Topic, @TopicCode, @Description) INSERT INTO Tags.tblSubjectTopic (SubjectId, TopicId) VALUES(@SubjectId, @@IDENTITY) COMMIT TRAN END TRY BEGIN CATCH DECLARE @Error VARCHAR(1000) SET @Error= 'ERROR NO : '+ERROR_NUMBER() + ', LINE NO : '+ ERROR_LINE() + ', ERROR MESSAGE : '+ERROR_MESSAGE() PRINT @Error ROLLBACK TRAN END CATCH And my collegue was writing it like the below one BEGIN TRY BEGIN TRAN INSERT INTO Tags.tblTopic (Topic, TopicCode, Description) VALUES(@Topic, @TopicCode, @Description) INSERT INTO Tags.tblSubjectTopic (SubjectId, TopicId) VALUES(@SubjectId, @@IDENTITY) COMMIT TRAN END TRY BEGIN CATCH DECLARE @Error VARCHAR(1000) SET @Error= 'ERROR NO : '+ERROR_NUMBER() + ', LINE NO : '+ ERROR_LINE() + ', ERROR MESSAGE : '+ERROR_MESSAGE() PRINT @Error ROLLBACK TRAN END CATCH Here the only difference that you will find is the position of writing Begin TRAN. According to me the methodology of my collegue should not work when an exception occurs i.e. Rollback should not get executed because TRAN does'nt have scope. But when i tried to run both the code, both was working in the same way. I am confused to know how does TRANSACTION works. Is it scope free or what ?

  • maximum string length quota error consuming WCF webservice from Biztalk.

    - by TygerKrash
    I'm getting this error message "The Maximum string content length quota (8192) has been exceeded while reading XML data. This quotea may be increased by changing the MaxStringContentLength property on the XmlDictionaryReaderQuotas object used when creating the XML reader" In the one of my orchestrations that consumes a wcf webservice (stacktrace indicates the receive shape is where the issue is), It is likely that the response is very large. looking at some of the other questions with this error message the solution is to change a WCF bindings setting in the configuration file. However I can't find these configuration settings when I'm using biztalk. They don't seem to be generated anywhere, should I be trying to add them to BTSNTSVc.exe.config. Any suggestions welcome.

  • How do I fix "error 1004, 0, Unable to find property" in an Entity Framework 4 WinForms application?

    - by Ivan
    I've designed an EF4 model (quite complex inheritance, lots of small tables incl. multiple self-referencing), generated (table-per-type) a database and inserted some basic data manually. It works fine in an ASP.Net Dynamic Data Entities web application with full automatic scaffolding. But when in a WinForms application using the same model (I share it as a part of a class library) I construct a query and bind a combo box to it (the way it's shown here), I get an InnerException {"Internal .NET Framework Data Provider error 1004, 0, Unable to find property... I've found a question about the same problem here (incl. a sample to reproduce the error) but no answer. I use final Visual Studio 2010, no beta.

  • Why can't I access the facebook friends list after reopening a session in ios

    - by user1532390
    I am upgrading to the facebook 3.0 sdk for ios. Things went well, until I tried to open an existing session after relaunching the application. I am trying to access the list of friends for the facebook user. if ([[FBSession activeSession] isOpen]) { [request startWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) { //do something here }]; }else{ [[self session] openWithCompletionHandler:^(FBSession *session, FBSessionState status, NSError *error) { if ([self isValid]) { [request startWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) { //log this error we always get NSLog(@"%@",error); //do something else }]; } }]; } However I get this error: Error Domain=com.facebook.sdk Code=5 "The operation couldn’t be completed. (com.facebook.sdk error 5.)" UserInfo=0x1d92ff40 {com.facebook.sdk:ParsedJSONResponseKey={ body = { error = { code = 2500; message = "An active access token must be used to query information about the current user."; type = OAuthException; }; }; code = 400; }, com.facebook.sdk:HTTPStatusCode=400} I've found that if I use the FBSession reauthorize method it allows me to complete the request without error, but it also means I must show UI or switch apps every time we relaunch the application which is unacceptable. Any suggestions on what I should be doing differently?

  • Mac Console.app not logging any messages

    - by karl_
    I recently attempted to overcome the 500 message limitation on console logs using the advice provided here: Mac: Extend or disable 500 Messages Limit of Console I copied the PLIST file onto my desktop, made the modifications, and re-copied into the LaunchDaemon folder. No dice. Unfortunately, this also broke logging in general- the console hasn't logged a message since I attempted this switch. I even went back and undid my changes. Still no logs. What's going on? Is there a way to reinstall Console.app, or revert to original settings?

  • Unknown error in Producer/Consumer program, believe it to be an infinite loop.

    - by ray2k
    Hello, I am writing a program that is solving the producer/consumer problem, specifically the bounded-buffer version(i believe they mean the same thing). The producer will be generating x number of random numbers, where x is a command line parameter to my program. At the current moment, I believe my program is entering an infinite loop, but I'm not sure why it is occurring. I believe I am executing the semaphores correctly. You compile it like this: gcc -o prodcon prodcon.cpp -lpthread -lrt Then to run, ./prodcon 100(the number of randum nums to produce) This is my code. typedef int buffer_item; #include <stdlib.h> #include <stdio.h> #include <pthread.h> #include <semaphore.h> #include <unistd.h> #define BUFF_SIZE 10 #define RAND_DIVISOR 100000000 #define TRUE 1 //two threads void *Producer(void *param); void *Consumer(void *param); int insert_item(buffer_item item); int remove_item(buffer_item *item); int returnRandom(); //the global semaphores sem_t empty, full, mutex; //the buffer buffer_item buf[BUFF_SIZE]; //buffer counter int counter; //number of random numbers to produce int numRand; int main(int argc, char** argv) { /* thread ids and attributes */ pthread_t pid, cid; pthread_attr_t attr; pthread_attr_init(&attr); pthread_attr_setscope(&attr, PTHREAD_SCOPE_SYSTEM); numRand = atoi(argv[1]); sem_init(&empty,0,BUFF_SIZE); sem_init(&full,0,0); sem_init(&mutex,0,0); printf("main started\n"); pthread_create(&pid, &attr, Producer, NULL); pthread_create(&cid, &attr, Consumer, NULL); printf("main gets here"); pthread_join(pid, NULL); pthread_join(cid, NULL); printf("main done\n"); return 0; } //generates a randum number between 1 and 100 int returnRandom() { int num; srand(time(NULL)); num = rand() % 100 + 1; return num; } //begin producing items void *Producer(void *param) { buffer_item item; int i; for(i = 0; i < numRand; i++) { //sleep for a random period of time int rNum = rand() / RAND_DIVISOR; sleep(rNum); //generate a random number item = returnRandom(); //acquire the empty lock sem_wait(&empty); //acquire the mutex lock sem_wait(&mutex); if(insert_item(item)) { fprintf(stderr, " Producer report error condition\n"); } else { printf("producer produced %d\n", item); } /* release the mutex lock */ sem_post(&mutex); /* signal full */ sem_post(&full); } return NULL; } /* Consumer Thread */ void *Consumer(void *param) { buffer_item item; int i; for(i = 0; i < numRand; i++) { /* sleep for a random period of time */ int rNum = rand() / RAND_DIVISOR; sleep(rNum); /* aquire the full lock */ sem_wait(&full); /* aquire the mutex lock */ sem_wait(&mutex); if(remove_item(&item)) { fprintf(stderr, "Consumer report error condition\n"); } else { printf("consumer consumed %d\n", item); } /* release the mutex lock */ sem_post(&mutex); /* signal empty */ sem_post(&empty); } return NULL; } /* Add an item to the buffer */ int insert_item(buffer_item item) { /* When the buffer is not full add the item and increment the counter*/ if(counter < BUFF_SIZE) { buf[counter] = item; counter++; return 0; } else { /* Error the buffer is full */ return -1; } } /* Remove an item from the buffer */ int remove_item(buffer_item *item) { /* When the buffer is not empty remove the item and decrement the counter */ if(counter > 0) { *item = buf[(counter-1)]; counter--; return 0; } else { /* Error buffer empty */ return -1; } }
