Posted By:      Posted Date: August 25, 2010    Points: 0   Category :ASP.Net
 

Good afternoon.

I'm trying to put an AutoCompleteExtender working, but i'm having an error, that i discovered with Fiddler, that is the reason that the autocomplete doesn't work:

Parameter names ending with "specified" added to web service method call

Linq2Sql error: "Invalid attempt to call Read when reader is closed."

  

I've read up on this error from other posts and on other sites, but haven't found a solid resolution to the issue yet. My setup is as follows:

I have a RepositoryBase class that fields certain db calls that all repositories need to perform. In one such call, "GetSecurityGroup", it works most of the time, but will seemingly at random throw an exception with the error "Invalid attempt to call Read when reader is closed." All other Repository classes inherit from this one, and they all use the same DataContext object, which I understand isn't thread safe. Since there could be multiple calls to the DataContext object on the same page, perhaps one is using the DataContext when the next tries to do so. I'm not sure. What can I do to ensure this doesn't happen?


Parameter Data changing between DataSource_Inserting and the BLL call

  


Hi,

I have a problem when trying to validate data on insertion (and possibly update, didnt try it yet) .


I use a formview in insert mode, linking to a custom BLL that then link to a DAL to insert data into a table. The problem is the parameter data is changing between the Datasource inserting event and when the BLL insert method is called. 2 field, that cannot be null in the database, have default value added to them. Bot sure how to explain so well so 'ill post some picture explaining :


This is the form I use, I enter only test in the textbox for the value Nom


this is the trace for my DataSource_Inserting event, as you can see, only the "Nom" value is non-null


But then, right after the event is done and the call is made to the BLL, the value for "Sexe" and "DateDeNaissance" has been changed to some default value, namely 0 and Jan 1, year 1.



This of course is causing problem because if the user does not provide value for "Sexe" and "DateDeNaissance" then I want t

SharePoint ASPX Web Service Call Error

  
I have developed an ASPX page using VS2005. This page simply queries a SharePoint list through a WSS web service using CAML and takes the results and populates a DataTable and binds it to a DataView.

Issues in GetItemDataSources web service call in 2008 Report Server R2

  
Hi, I'm using Reporting Services web services endpoint ReportService2005.asmx with 2008 report server R2 and I'm facing some issues in getting the data source names for a report definition using the GetItemDataSources web service. The problem is that the data source names returned are different from the names of the actual data sources on the report server. The report has the following data sources: 0 1 _0 _A Data Source And the names returned by the GetItemDataSources for 2008 report server R2 is: AutoGen_0 AutoGen_1 AutoGen__0 AutoGen__A Data_Source When I make the same calls using a 2005 report server, the names returned are the same as that in the report definition. To summarize, only numeric data source names are changed to "Autogen_<number>"(eg. Autogen_0), data source names beginning with "_" are changed to "Autogen_<data source name>"(eg. AutoGen__A)  and spaces are replaced by an "_".   What is the problem for the data source names returned for 2008 report server R2? Or has there been any change in the way in which report server stores the data source names? Thanks, Kulbhushan Singhal.

syntax problem passing parameter into Indexing Service Query

  
Hi everyone, I have the following query which works fine: select OriginalFileName from Document_Entries where EntryType like 'File%' and substring(entry,charindex('file_',entry),LEN(entry)) in (  SELECT filename FROM OPENQUERY(MySearchCat, 'SELECT Directory, FileName FROM SCOPE() WHERE    CONTAINS('' "green" '') ') )  It finds all documents in the document system which contain the word "green" using the index catalog.  My problem is that i need to include this query in a larger stored procedure which accepts a parameter for key words amongst others. I can't work out the syntax to get the @keywords parameter into query. The closest I've come is the following which runs but comes back with "incorrect syntax near keyword 'green'".  The @keywords parameter will contain any key words the user enters.   declare @keywords nvarchar(500) set @keywords='green'   Declare @query nvarchar(max) set @query = ' select OriginalFileName from Document_Entries where EntryType like ''File%'' and substring(entry,charindex(''file_'',entry),LEN(entry)) in (  SELECT filename FROM OPENQUERY(MySearchCat, ''SELECT Directory, FileName FROM SCOPE() WHERE    CONTAINS(''' + @keywords + ''') '')     )  )' exec(@query)   Any ideas? thanks Gus

jQuery Call to Web Service, with Punctuation

  
Hello everyone! I hope you're all having a nice week so far. I'm trying to call a web service and the passed string may have punctuation, depending on what the user types in. I currently have an HTML textbox and a jQuery call to the .NET web service.  I definitely think the string with punctuation fails because jQuery will send the string wrong, so I tried a few different javascript encoding functions I could find.  I was never able to encode it successfully and decode it in .NET, saving the string with punctuation.   Basically I have a textbox that a user can update their status in.  If the user wants to use punctuation, I'd like them to be able to.  How can I accomplish this with jQuery and .NET?

passing messageContract object to a WCF Service method using Soap - not as a method parameter

  
i want a web application to create a service reference to my WCF service, insert information to the header of the soap call and call my WCF method. my WCF supports soap operations (also there is an endpoint in the config). i read about MessageContract attribute and declared one in the interface file: [ServiceContract] public interface IBasicService { [OperationContract] [WebGet(UriTemplate = "GetData?value={value}")] // Add support for HTTP GET Requests string GetData(int value); } [MessageContract] public class BasicServiceHeader { [MessageHeader] public string myString; } the implementation of the contract : public class BasicService : IBasicService { public string GetData(int value) { return string.Format("You entered: {0}", value); } } i don't want the BasicServiceHeader to be passed as a parameter of GetData function , i want to keep the function signature as it is (without a BasicServiceHeader parameter) and to extract the BasicServiceHeader inside the function, (just like using soapHeader) can i do that ?

Send/open timeouts on WAS-hosted WCF service with named pipe orTCP binding, per-call instancing

  
We have a client that sends requests to a per-call WCF service (WAS hosted, NP binding, same machine) in a loop. The WCF service calls an external EXE to process requests. The operations on the service can take a few seconds, or a few hours. To combat this, we have sendTimeout=00:05:00, receiveTimeout=00:05:00 and a built-in circuit-breaker on the service that kills the external process after 00:05:00. Any service-side errors are returned to the client as FaultExceptions.  On the client, FaultExceptions are logged and the client proxy is aborted (proxy.Abort()). The client has configurable multithreading. In this example, it is running 3 threads, each of which creates a proxy, makes a call, and closes the proxy (or aborts it if an exception was received). Since the service is instanced as per-call, and it never receives more than 3 simultaneous calls (each of which being followed by a .Close() or .Abort() on the proxy), I would not expect the client to be getting timeouts during the send, but I am. In fact, the send timeouts I am receiving would seem to imply that the WCF service is hitting the default session limit, even though the class is explicitly marked with [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)]. I put some trace logging on the client and I can see that the timeout is occurring when the proxy is being created. sendTimeout seems to
