Passing List to WCF Service

Posted By:      Posted Date: September 15, 2010    Points: 0   Category :WCF
Hi, All, I'm not sure this has been covered before.  I did search, but not sure that any of those responses apply: I'm relatively new to WCF. I have the following classes:  PostAddress, EmailAddress, PhoneNumber, ContactInformation and, Person.  The ContactInformation contains each a List<PostAddress>, List<EmailAddress>, List<PhoneNumber> property.  The Person class has a ContactInformation property. When I pass my Person object to my WCF service, my ContactInformation Lists values are null.  For example: I create an address with: street, city, state, zip, country and add it to my List<PostAddress> I add the list to the Person's ContactInformation's List<PostAddress> Property I pass it to the WCF Service.  At that time, I have this: Person.ContactInformation.Addresses.Count = [the number of addresses in the list] Person.ContactInformation.Addresses[index].property = null My service inferface looks like this (I haven't fully sketched it all out yet): [   ServiceContract]     public interface IMyService { [   OperationContract]     bool FoundDuplicate( Person p ); [   OperationContract]     void SubmitNewMembership( Person p, Membership m ); } I'm using Visual Studio Ultimate 2010/.NET 4 on Windows 7 Professional Edition if that

Problem with passing an Image as binary through web service



I have a web service that is accessed by a windows forms application and receives updates like facility name, address, image etc. Everything works fine except the image data is not being passed to the windows app. I am saving the images in database on both sides, so when I pull it from the server I use the following code

if (!reader.IsDBNull(floorPlanOrdinal))

facility.FloorPlan = (byte[])reader["FloorPlan"];

I can see the facility.FloorPlan Dimentions as 103840 when I debug this method which means that the data is pulled from the database fine.

On the forms side though the dimentions become 0, all other values pass fine except this. Here is the facility property in the web service on server side.

TSQL: Passing array/list/set to stored procedure (MS SQL Server)

Passing array/list/set to stored procedure is fairly common task when you are working with Databases. You can meet this when you want to filter some collection. Other case - it can be an import into database from extern sources. I will consider few solutions: creation of sql-query at server code, put set of parameters to sql stored procedure's parameter with next variants: parameters separated by comma, bulk insert, and at last table-valued parameters (it is most interesting approach, which we can use from MS SQL Server 2008). Ok, let's suppose that we have list of items and we need to filter this items by categories ("TV", "TV game device", "DVD-player") and by firms ("Firm 1", "Firm2", "Firm 3). It will look at database like this So we need a query which will return us list of items from database. Also we need opportunity to filter these items by categories or by firms. We will filter them by identifiers. Ok, we know the mission. How we will solve it? Most easy way, used by junior developers - it is creating SQL-instruction with C# code, it can be like this List<int> categories = new List<int>() { 1, 2, 3 };   StringBuilder sbSql = new StringBuilder(); sbSql.Append( @" select i.Name as ItemName, f.Name as FirmName, c.Name as CategoryName from Item i inner join Firm f on i.FirmId =

Update SharePoint List item using UpdateListItem web service with javascript

I'm using the Custom_AddListMenuItems function in a CEWP to add a menu item to each list item to Archive that item. This is achieved by updating a choice field in the item to 'Archived'. I'm trying to do this using the web service UpdateListItem web service to update the item using Javascript, but I can not find the correct code that updates the list item. I'm using this code:     var ctx=currentCtx;     var ciid=currentItemID;     var xmlHttp=null;     if (confirm("Are you sure you want to Archive this item?"))     {         var soapRequest = '<?xml version="1.0" encoding="utf-8"?>'+             '<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">'+             '    <soap:Body>'+             '        <UpdateListItems xmlns="http://schemas.microsoft.com/sharepoint/soap/">'+         

Error calling WCF service that is returning list.".Debugging resource strings are unavailable ......

Ok.this is just making me frustrated... Here is step by step of what I am trying to do (& not able to) 1. I am calling WCF service hosted in a SharePoint 2010 site from a silverlight app in same domain (So no cross doman I guess). 2. I use Linq to Sharepoint for querying the DB. 3. I am having a list "machines" in Sharepoint 2010 that is having a lookup column from Other list called "part" 4. My WCF method GetAllMachines() works perfectly well when it skips the lookup column "partname" & returns List of type machineitem. 5. But problem occurs when I add machineitemobject.parts.partsname in my Linq to Sharepoint query . My service gives the error not found Async_ExceptionOccurred] Arguments: Debugging resource strings are unavailable." 6. Note that return type of my Method is List<machinesitem> 7. The point to note here is that I use SPMETAL tool to generate the LINQ class that maps the lists . So When I try to query the lookup column it tries to add List item of the type class & that is what causing the error. Is it because I am not using datacontract in my service (but it returns the strings & all private members of machines list e.g. name,title etc) Is it making the attribute Serialisable will solve the error ??? I am kind of lost in it ...Plss help!!   Thanks

How to query for id's of the fields with List Data Retrival Services Query() web service

Since i marked a post as answer in my previous topic, it seems that people dont visit the topic anymore as they see it as "answered" while it actually is only partially answered. So i guess i have to ask again in a different topic.    I need to get data from Sharepoint Server (3.0 i belive) for my Integration Services project. For that i use Sharepoint's webservices. I've read tutorials and downloaded sample programs to talk to WSS web services. I realise i have two ways to get items in a list: Use Query() or GetListItems(). Problem is, GetListItems() has a mandatory "Row limit" field and i might have to import ALOT of fields, so i thought Query() is better for me.  But, when using GetListItems(), the WSS returns the ID of the fields (for example, for a field of type user, something like "395;Ivanov Ivan Ivanovich" is returned) but when using Query() for the same list, WSS returns only the field value ("Ivanov Ivan Ivanovich") without the ID. I need it to return the ID as well. How can i set it up, on my side or server side, so i would receive the ID's, not only the values of the fields that are actually linking to something by ID when i use Query() web service?     

Passing return value from a Web Service to a label in a Form View

I am using JavaScript to call a web service. The JS is correctly receiving and passing the web service information. At the moment, the web service returns a country name as a string to a JavaScript alert pop up box as follows:ret = CountryRegionsWebService.GetTranslatedCountryShortName(ddl1_value, ddl2_value, OnComplete, OnTimeOut, OnError);function OnComplete(args) { alert(args); } I want to change this so that web service returns the country name to a label inside an insert item template of a form view. Is there a way to pass in the label variable to the OnComplete function signature and still account for the variable args?, such as: Server Side Declaration of JavaScript ddl2.Attributes.Add("onChange", "JavaScript:OnComplete('" + lab5.ClientID + "', '" + "args" + "');"); Client Side JavaScript function OnComplete(lab5_id, args) { var lab5 = document.getElementById(lab5_id); lab5.innerHTML = args; }  

Cannot delete rows in a list via Lists web service's UpdateListItems-function, even though I am abl

Hi all, I'm trying to delete some rows in a SharePoint 2010 Foundation list via Lists.asmx -web service's UpdateListItems. The web service is called from BizTalk. I am able to create rows, but for some reason delete fails. I also use "GetListItems"-function without problems. The exception I get is Microsoft.SharePoint.SoapServer.SoapServerException. The message is "Cannot access a closed Stream." The updates-element of the UpdateListItems-function is as follows (well, a part of it, the real one has more Method-elements, but you get the gist..): <Batch OnError="Continue" ListVersion="1"> <Method ID="1" Cmd="Delete"> <Field name="ID">1900</Field> <Field name="IMEI">GFA-687</Field> </Method> <Method ID="2" Cmd="Delete"> <Field name="ID">1901</Field> <Field name="IMEI">OVG-567</Field> </Method> <Method ID="3" Cmd="Delete"> <Field name="ID">1902</Field> <Field name="IMEI">OXI-570</Field> </Method> </Batch> I've also tried that Batch without the IMEI-information, as well as with a valid ViewName. Why cannot I delete when I can clearly modify/create rows - what's up with th

List of Objects in Declarative Service

I am trying to create a WCF workflow service that accepts requests from a user to add a new user.  I want to add this "user to be approved" to a list of users List<PendingUsers> and wait until an approver approves one. Then the workflow will remove the approved user from the list and add it to the database. Requirements: 1. Pending users should not be added to the database, they should be maintained in a variable until approved. 2. The second ReceiveAndSendReply will return the list of all pending users.   I have created a service with a flowchart that has a flowchart variable that is the list of pending users. The problem is after each call it is lost. I am assuming the workflow is unloading. Is there another approach I can take or some way to keep the List of Users from unloading between calls.

How to use SharePoint 2007 list data in Reporting Service (Visual Studio) 2008?

Jeez - I have been googling left and right, and tried all the suggestions. No luck in getting it to work. I am using Reporting Service 2008 tools in my VS2008, trying to create a simple report using SharePoint 2007 data (from a simple list). Here is what I've been doing: Created a simple SharePoint list in a test site - only one column (Title) with one record of data. Started Visual Studio 2008 and created a new Report Server Project Wizard project. I named the data source "dsTest". Type: "XML". As connection string I used: http://site/subsite/subsite/_vti_bin/lists.asmx. Credentials: "Use Windows Authentication (Integrated Security)". Clicked Next and arrived at the "Design the Query" form. I entered this in the Query string box: <Query> <Method Namespace="http://schemas.microsoft.com/sharepoint/soap/" Name="GetListItems" /> <SoapAction>http://schemas.microsoft.com/sharepoint/soap/GetListItems</SoapAction> </Query> Clicking Next I get this error: An error occurred while the query design method was being saved. Failed to execute web request for the specified URL. Soap Fault: Exception of type 'Microsoft.SharePoint.SoapServer.SoapServerException' was thrown. Now if I view the Details when trying it inside the Query Builder I get this: <errorstring xmlns="http://schemas.mi

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

SharePoint 2007 - Survey list - Getting user's Windows account ID from a web service using display

Surveys...grrrr.   I am developing a .NET console application that accesses survey data from a single survey list using the MOSS web service "Lists".   I am able to enumerate the survey list and get to the items except for the author of the survey response.  When I get to the column ows_Author, it appears to be a lookup value formatted like this:  "1066;#JOHN DOE".   How can I, using web services alone, lookup the corresponding Windows login ID of that user?  If I go to the survey in SharePoint and click on the name in the view, it takes me to a site-based user profile page that does show the account ID I want.  The page that displays appears to be a virtualized page like this "_layouts/userdisp.aspx?ID=1066".   What I really need is JOHN DOE's account ID like "domain\id". Can I get to this with the data I have available? Thanks
