 when I calling web service from SSIS. I setup HTTP connection and tested without any problem; download WSDL without any problem; I did exactly as the link: http://msdn.microsoft.com/en-us/library/ms181267.aspx.

VS2005 calling VS2010 asmx service returns empty string


Anyone have any experience with this?

We are using VS 2005 for the front end, and vs 2010 for the web services part (asmx), not wcf yet.


Web service works just like the vs2005 when run locally, no problems.


Connecting to it from a test app returns an empty string. Connecting to a 2005 app doesn't!

Anyone run into this before or have a suggestion? Surely vs 2005 can connect to web services from a later version?

SELECT statement to return NULL by matching data from another table.

Hi,I am fairly new at SQL and I have been struggling for days now trying to find an answer to my problem and i have come to the point where i have run out of ideas and about to give up. I'm hoping someone can put me in the correct path. The problem I have 3 table Table 1 Department" has the following columns: REF, NAME Table 2  "Department_Collection" has the following columns: REF, DEPARTMENT_REF, MANAGER_REF, STORE_REF, ACTIVE Table 3 Store" has the following columns: REF, NAME, STORE_ID  What i am trying to do is to take all the rows in the Department table and get a matching row (DEPARTMENT.NAME, DEPARTMENT_COLLECTION.REF) from the Department_Collection table, if it does not match any then still display DEPARTMENT.NAME but mark DEPARTMENT_COLLECTION.REF as null. I have tried the following select statement but it seem to remove all null values when supplied with a 'storename' SELECT DEPARTMENT.NAME, DEPARTMENT_COLLECTION.REF FROM DEPARTMENT_COLLECTION right outer join DEPARTMENT on DEPARTMENT_COLLECTION.DEPARTMENT_REF = DEPARTMENT.REF left outer join STORE on DEPARTMENT_COLLECTION.STORE_REF = STORE.REF where STORE.NAME = 'storename' order by DEPARTMENT.NAME   Any help will be greatly appreciated. Thanks

Calling an asp.net web service from jQuery

As I have post it in earlier post that jQuery is one of most popular JavaScript library in the world amongst web developers Lets take a example calling ASP.NET web service with jQuery . You will see at the end of the example that how easy it is to call a web service from the jQuery. Let's create a simple Hello World web service. Go to your project right click->Add -> New Item and select web service and add a web service like following.   Now modify the code of web service like following. [WebService(Namespace = "http://tempuri.org/")][WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)][System.ComponentModel.ToolboxItem(false)]// To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. [System.Web.Script.Services.ScriptService]public class HelloWorld : System.Web.Services.WebService{ [WebMethod] public string PrintMessage() { return "Hello World..This is from webservice"; }} Here please make sure that [System.Web.Script.Services.ScriptService] is un commented because this attribute is responsible for allowing web service to be called by Client side scripts. Now to call this  web service from jquery we have to include jQuery Js like following. I am already having in my project so i don't need to include in project just need to add script tag like following. <script type="t

Can not get excel connection when calling an SSIS package from ASP

I have an SSIS package importing data from excel. I have coded it and deployed it on the sql 2008 server. I then execute it via a stored procedure with the following: select @cmd = 'C:\"Program Files (x86)\Microsoft SQL Server\100\DTS\Binn\DTExec.exe" /sq "HRIS"' select   @cmd = @cmd + ' /SET \Package.Variables[User::path].Properties[Value];"' + @path + '"' exec   @rtn = master..xp_cmdshell @cmd   This works fine when  i execute it on my local machine. But when I try to call this Stored proc from my asp app (classic asp, not .net) I get the error: Code: 0xC0202009 Source: HRIS Connection manager "SourceConnectionExcel" Description: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80004005. An OLE DB record is available. Source: "Microsoft JET Database Engine" Hresult: 0x80004005 Description: "Unspecified error".

calling a web service on a remote server from a ASPX page (web site project VS2005)

HI,I am maintaining a web site project in VS2005 and have to call a new web service on a remote server. I've done add web reference, and created the .wsdl and .discomap files in the app_webReference folder.  When I try to create a object representing the web service in the code ( wsnamespace.serviceName ws = new wsnamespce.serviceName(); ) the code wouldn't compile.The web site project is already calling other web services. When I right click on the type representing the web service and "go to definition" it takes me to a proxy class (derived from of course SoapHttpClientProtocol) in the metadata. I think this is what's missing for  the new web service i'm trying to call. Have I missed any steps?Thanks in advance.-me

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
