  • Unable to make 2 parallel TCP requests to the same TCP Client

    - by soldieraman
    Error: Unable to read data from the transport connection: A blocking operation was interrupted by a call to WSACancelBlockingCall Situation There is a TCP Server My web application connects to this TCP Server Using the below code: TcpClientInfo = new TcpClient(); _result = TcpClientInfo.BeginConnect(<serverAddress>,<portNumber>, null, null); bool success = _result.AsyncWaitHandle.WaitOne(20000, true); if (!success) { TcpClientInfo.Close(); throw new Exception("Connection Timeout: Failed to establish connection."); } NetworkStreamInfo = TcpClientInfo.GetStream(); NetworkStreamInfo.ReadTimeout = 20000; 2 Users use the same application from two different location to access information from this server at the SAME TIME Server takes around 2sec to reply Both Connect But One of the user gets above error "Unable to read data from the transport connection: A blocking operation was interrupted by a call to WSACancelBlockingCall" when trying to read data from stream How can I resolve this issue? Use a better way of connecting to the server Can't because it's a server issue if a server issue, how should the server handle request to avoid this problem

  • UILocalNotification crash

    - by Miky Mike
    Hi everyone, could you please help me ? I'm setting up an UILocalNotification and It crashes when I try to set its userInfo dictionary. My dictionary is not empty (It contains 88 objects). Here is the code : NSDictionary* myUserInfo = [NSDictionary dictionaryWithObject: fetchedObjects forKey: @"textbody"]; UILocalNotification *localNotif = [[UILocalNotification alloc] init]; if (localNotif == nil) return; // défining the interval NSTimeInterval oneMinute = 60; localNotif.timeZone = [NSTimeZone localTimeZone]; NSDate *fireDate = [[NSDate alloc]initWithTimeIntervalSinceNow:oneMinute]; localNotif.fireDate = fireDate; localNotif.userInfo = myUserInfo; [fetchedObjects release]; and the console gives me this : Property list invalid for format: 200 *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'unable to serialize userInfo: (null)' Any idea ?

  • Creating share programmatically fails with error 9

    - by Christopher
    Directory.CreateDirectory("C:\MyTestShare") Dim managementClass As New ManagementClass("Win32_Share") Dim inParams As ManagementBaseObject = managementClass.GetMethodParameters("Create") inParams.Item("Description") = "My Files Share" inParams.Item("Name") = "My Files Share" inParams.Item("Path") = "C:\MyTestShare" inParams.Item("Type") = 0 If (DirectCast(managementClass.InvokeMethod("Create", inParams, Nothing).Properties.Item("ReturnValue").Value, UInt32) <> 0) Then Throw New Exception("Unable to share directory.") End If I am using the following code to set up a share, but I am always getting a return value of 9 which means invalid name. I am passing a string and have tried to use an explicit string and I still get error 9. I am creating the share remotely rather than on local machine however. Not sure if that matter.

  • Can a grails controller extend from a base class? How to make it so grails doesn't blow up?

    - by egervari
    I wrote a base class to help build my controllers more quickly and to remove duplication. It provides some helper methods, default actions and some meta programming to make these things easier to build. One of those methods in the base class is like this: def dynamicList(Class clazz) { def model = new LinkedHashMap() model[getMapString(clazz) + "s"] = list(clazz) model[getMapString(clazz) + "sTotal"] = count(clazz) model } The action that calls it, also in the base class, is this: def list = { dynamicList(clazz) } Unfortunately, when I go to list action in the controller subclass that inherits the base class when my application is deployed, I get this exception: groovy.lang.MissingMethodException: No signature of method: groovy.lang.MissingMethodException.dynamicList() is applicable for argument types: (java.lang.Class) values: [class project .user.User] at project.user.UserController$_closure1.doCall(UserController.groovy:18) at project.user.UserController$_closure1.doCall(UserController.groovy) at java.lang.Thread.run(Thread.java:619) How can I hit grails over the head and just tell it do what I want it to do? My controller unit tests run just fine, so grails' run-time is totally at fault :/ Ken

  • Accessing WPF Template for Custom Control from Code behind

    - by Ashwani Mehlem
    Hi, i am trying to access a named grid inside a default template for a custom control from code behind. But it seems that the template for the control is null, even after calling ApplyTemplate(). Is that impossible inside the controls constuctor? Here's the code: Generic.xaml: ... <ControlTemplate TargetType="{x:Type local:TimeTableControl}"> <Grid Name="ContentGrid"> </Grid> </ControlTemplate> ... TimeTableControl.cs: public TimeTableControl() { ApplyTemplate(); contentGrid = (Grid)(Template.FindName("ContentGrid", this)); //Line above causes null-pointer-exception ... }

  • Exchange 2003 Public Folder Replica list

    - by Niall
    Hi, I am trying to update a replica list on a Exchange 2003 public folder. I am using the WMI namespace exchange_publicfolder to try and add an Exchange server (using the servers DN) to the AddReplica procedure. Every time I run this I get an invalid parameter as an exception. Below is the code that I am using to do this. WMI.Connect(Server, credentials) Using WMISearcher As New ManagementObjectSearcher(WMI.Scope, & _ New ObjectQuery(String.Format("SELECT * FROM Exchange_Publicfolder WHERE path='{0}'", Name))) Using PublicFolder As ManagementObjectCollection = WMISearcher.Get For Each Folder As ManagementObject In PublicFolder Dim BaseFolder As ManagementBaseObject = Folder.GetMethodParameters("AddReplica") BaseFolder("path") = ServerDN Folder.InvokeMethod("AddReplica", BaseFolder, Nothing) Next End Using End Using I have used WMI before and I can see that the call is connecting to the correct public folder because i can itterate through the properies once the query has executed. I am not sure what I am doing wrong here. If anyone has any ideas or comments the please let me know. Thanks Niall

  • Bad temperature sensors on Foxconn motherboard?

    - by Gawain
    I have a system with a Foxconn V400 series motherboard and AMD Athlon 3000+ processor. Ever since I got it a few years ago the fans (particularly the CPU fan) have been really loud. So recently I installed SpeedFan to see why they were running so fast. SpeedFan reported the CPU temperature to be 32C, and one motherboard sensor at about 26C. But the other two motherboard sensors were reporting 78C and 64C respectively. Naturally the fans were both maxed out because of this, with the CPU fan at 5800rpm and the case fan at 2400rpm. I opened the case and everything inside was literally cool to the touch, with the exception of the CPU heatsink which was slightly warm, but nowhere near 78C. It seems like the temperature sensors are either defective or being read incorrectly. Is there some way I can decrease my fan noise without risking damage to my processor? Some way to ignore those two temp sensors? Any help would be greatly appreciated.

  • T4MVC calling controller methods multiple times?

    - by Maslow
    I suspected there was some hidden magic somewhere that stopped what looks like actual method calls all over the place in T4MVC. Then I had a view fail to compile, and the stackTrace went into my actual method, not the generated code in T4MVC. <%=Ajax.ActionLink("Apply", "Apply", new RouteValueDictionary() { { "shortName", item.Shortname } }, new AjaxOptions() { UpdateTargetId = "masterstatus" })%> <%=Html.ActionLink("Apply",MVC.Alliance.Apply(item.Shortname),new AjaxOptions() { UpdateTargetId = "masterstatus" }) %> The second method threw an exception on compile because the method Apply in my controller has an [Authorize] attribute so that if someone that isn't logged on clicks this, they get redirected to login, then right back to this page. There they can click on apply again, this time being logged in. And yes I realize one is Ajax.ActionLink while the other is Html.ActionLink I did try them both with the T4MVC version. Is this a fluke or is it actually calling into the real methods and running my database calling code just to generate the views?

  • EF problem with entity re-ordering and uniqueness constraint

    - by wpfwannabe
    I am using Entity Framework and I've come to an interesting stumbling block. Let's say there is a db table "Item" with "sequence" column of type int (and others of course). Column "sequence" must be unique and it is used for (re)ordering of items. EF maps this table to "Item" class with "sequence" int property. Now let's say I want to swap position of two items by mutually exchanging each other's sequence number. Upon calling SaveChanges() EF throws an exception complaining about "sequence" uniqueness. It probably generates two UPDATEs and the first one probably fails. I assume that plain SQL solution to this issue is using a third UPDATE to introduce a unique sequence value in the process but I am stuck with EF. Any thoughts?

  • How to handle request-wise DB transactions in ASP.NET MVC?

    - by Dario Solera
    I'm using SubSonic 3.0 (SimpleRepository) to handle database access in my ASP.NET MVC 1.0 application. It would be nice to handle a transaction for every web request, committing if everything went smooth and rolling back in case of exception. Is this possible? If so, how? I know this topic has been discussed many times, but I just couldn't find a satisfactory answer. I have built my own solution (create a TransactionScope in the controller, then commit/rollback in OnActionExecuted), but it turns out to be very unreliable.

  • Identifying NHibernate proxy classes

    - by Marc Gravell
    I'm not an NHibernate user; I write a serialization utility library. A user has logged a feature-request that I should handle NHibernate proxy classes, treating them the same as the actual type. At the moment my code is treating them as unexpected inheritance, and throwing an exception. The code won't know in advance about NHibernate (including no reference, but I'm not aftaid of reflection ;-p) Is there a robust / guaranteed way of detecting such proxy types? Apparently DataContractSerializer handles this fine, so I'm hoping it is something pretty simple. Perhaps some interface or [attribute] decoration. Also, during deserialization; at the moment I would be creating the original type (not the NHibernate type). Is this fine for persistence purposes? Or is the proxy type required? If the latter; what is required to create an instance of the proxy type?

  • creating a Menu from SQLite values in Java

    - by shanahobo86
    I am trying to create a ListMenu using data from an SQLite database to define the name of each MenuItem. So in a class called menu.java I have defined the array String classes [] = {}; which should hold each menu item name. In a DBAdapter class I created a function so the user can insert info to a table (This all works fine btw). public long insertContact(String name, String code, String location, String comments, int days, int start, int end, String type) { ContentValues initialValues = new ContentValues(); initialValues.put(KEY_NAME, name); initialValues.put(KEY_CODE, code); initialValues.put(KEY_LOCATION, location); initialValues.put(KEY_COMMENTS, comments); initialValues.put(KEY_DAYS, days); initialValues.put(KEY_START, start); initialValues.put(KEY_END, end); initialValues.put(KEY_TYPE, type); return db.insert(DATABASE_TABLE, null, initialValues); } It would be the Strings inserted into KEY_NAME that I need to populate that String array with. Does anyone know if this is possible? Thanks so much for the help guys. If I implement that function by Sam/Mango the program crashes, am I using it incorrectly or is the error due to the unknown size of the array? DBAdapter db = new DBAdapter(this); String classes [] = db.getClasses(); edit: I should mention that if I manually define the array: String classes [] = {"test1", "test2", "test3", etc}; It works fine. The error is a NullPointerException Here's the logcat (sorry about the formatting). I hadn't initialized with db = helper.getReadableDatabase(); in the getClasses() function but unfortunately it didn't fix the problem. 11-11 22:53:39.117: D/dalvikvm(17856): Late-enabling CheckJNI

  • What happens to an ActiveX control (COleControl) after the call to OnDestroy() ?

    - by richj
    I have an ActiveX control written in C++ that runs in Internet Explorer 8. Most of the time (approx 90%) when the tab or browser containing the control is closed, there is an access violation like this: The thread 'Win32 Thread' (0x1bf0) has exited with code 0 (0x0). Unhandled exception at 0x77b3b9fd in iexplore.exe: 0xC0000005: Access violation reading location 0x65007408. The access violation occurs after the call to OnDestroy() but before the call to the control's destructor. The debug output says: No symbols are loaded for any call stack frame. The source code cannot be displayed. None of my code is present in the stacktrace, although perhaps the heap was corrupted at some earlier point during execution. What lifecycle events does an ActiveX control receive between the call to OnDestroy() and the control's destructor?

  • Is there any way to limit the size of an STL Map?

    - by Nathan Fellman
    I want to implement some sort of lookup table in C++ that will act as a cache. It is meant to emulate a piece of hardware I'm simulating. The keys are non-integer, so I'm guessing a hash is in order. I have no intention of inventing the wheel so I intend to use stl::map for this (though suggestions for alternatives are welcome). The question is, is there any way to limit the size of the hash to emulate the fact that my hardware is of finite size? I'd expect the hash's insert method to return an error message or throw an exception if the limit is reached. If there is no such way, I'll simply check its size before trying to insert, but that seems like an inelegant way to do it.

  • How to get this XmlAttribute

    - by user328738
    From the MusicBrainz REST service, I get the following xml: <artist-list offset="0" count="59"> <artist type="Person" id="xxxxx" ext:score="100"> ... Using WCF and XmlSerializationFormat, I'm able to get the type and id attributes... but How do I get the "ext:score" one? This works: public class Artist { [XmlAttribute("id")] public string ID { get; set; } [XmlAttribute("type")] public ArtistType Type { get; set; } But this doesnt: [XmlAttribute("ext:score")] public string Score { get; set; } It produces a serialization exception. I've also tried just using "score", but it doesn't work. Any help?

  • Why can't set cast an object from Excel interop?

    - by AngryHacker
    Trying to get a reference to the worksheets (using Excel interop): Excel.Application xl = new Excel.ApplicationClass(); Excel.Workbooks xlWorkBooks = xl.Workbooks; Excel.Workbook xlWorkBook = xlWorkBooks.Open(fileName, 0, false, 5, "", "", true, Excel.XlPlatform.xlWindows, "\t", false, false, 0, true, 1, 0); Excel.Worksheets xlWorkSheets = (Excel.Worksheets) xlWorkBook.Worksheets; // crashes The error is that it cannot cast it: Unable to cast COM object of type 'System.__ComObject' to interface type 'Microsoft.Office.Interop.Excel.Worksheets'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{000208B1-0000-0000-C000-000000000046}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)). Is my cast incorrect?

  • Cascading S3 Sink Tap not being deleted with SinkMode.REPLACE

    - by Eric Charles
    We are running Cascading with a Sink Tap being configured to store in Amazon S3 and were facing some FileAlreadyExistsException (see [1]). This was only from time to time (1 time on around 100) and was not reproducable. Digging into the Cascading codem, we discovered the Hfs.deleteResource() is called (among others) by the BaseFlow.deleteSinksIfNotUpdate(). Btw, we were quite intrigued with the silent NPE (with comment "hack to get around npe thrown when fs reaches root directory"). From there, we extended the Hfs tap with our own Tap to add more action in the deleteResource() method (see [2]) with a retry mechanism calling directly the getFileSystem(conf).delete. The retry mechanism seemed to bring improvement, but we are still sometimes facing failures (see example in [3]): it sounds like HDFS returns isDeleted=true, but asking directly after if the folder exists, we receive exists=true, which should not happen. Logs also shows randomly isDeleted true or false when the flow succeeds, which sounds like the returned value is irrelevant or not to be trusted. Can anybody bring his own S3 experience with such a behavior: "folder should be deleted, but it is not"? We suspect a S3 issue, but could it also be in Cascading or HDFS? We run on Hadoop Cloudera-cdh3u5 and Cascading 2.0.1-wip-dev.
