View 6 RepliesWe have a big portal with a lot of code written in classic asp + asp.net 2.0 + JavaScript. We are planning to slowly migrate to .net 3.5 framework with WCF Services. Currently the ASP.Net code is using some business layer to access the database. But most of the Classic ASP is using the old ADO code and directly accessing the data in the page itself. Now, we decided to add a WCF layer between the UI and Business which will be easier to implement with ASP.Net + 3.5, compared to Classic ASP. And we can't invest a lot of Man Hours in converting the Classic ASP pages to asp.net just yet. So we decided to Add a COM layer between Classic ASP and WCF services. So it will be like
Classic ASP -> COM -> CCW (COM Callable Wrapper - Interop) -> WCF -> Business for now.
Later on when we slowly convert the Classic asp pages to asp.net, the COM layer will be removed by default. But for now we are atleast pulling the Business code from Classic Asp pages. We are following this approach because we are not sure how to go about accessing the WCF Service directly from the Classic ASP code.
I have a web service which is in a folder within my application. This folder is only accesible to certain roles. I use this service in a page on root of the application but I block creation of the javascript or the service definition in the aspx page if the user is not in the role.
The problem is that when anonymous users try to access the page in the root of the application they are prompted for a user name and password. I hope I am clear. The code below is what I have set up in the ASPX page:

I have an Asp.net web service that I created using Visual Studio 2005. I can acess the web service in my test environment, call methods and return data as expected. If this web service is published to the outside world (Outside of the company firewall), it will return a null why this might be happening? The same code is being used,against the same database. The only difference is that the published website is giving back the null reference exception. If I type in the URL for the web service "https://secure.theSiteGeist.com/wsIndigo.asmx" a list of methods for the web service is displayed in my browser. Yet if I try and call any methods on the web service I get back the null reference exception. Note that the URL I posted above is not the real name of my web service, but is just used for reference sake.

I'm trying to use ASP.NET WCF Authentication Service from a Winforms Application.
I am referring to this article as a tutorial.

what is the cause of this and is there another approach I should take when I leverage ASP.NET authentication from Winforms?

View 1 RepliesI want to create a WCF Service to transfer data to our clients application(WPF). The Data I am trying to send is as follows.
ID Code Description unit Rate
1 104200000 LIVE GOAT NOS 25
2 104200000 LIVE GOAT2 NOS 25
3 104200030 LIVE GOAT3 KGS 10
4 104202030 Water LTR 5
and so on till ~ 11000 records.
What I have done so far is. Created a service which return a list of data.
public List<Classes.TariffData> GetTariffData() { var currentTariffData = new List<Classes.TariffData>(); using (var myConnection = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString)) { const string query = "select a.ID,a.Code,a.Description,a.unit,a.rate,a.rate3 from tariff.dbo.tariffdata a, tariff.dbo.code_history b where a.id = b.id and b.endofvalidity is null"; using (var myCommand = new SqlCommand(query, myConnection)) { using (var ad = new SqlDataAdapter(myCommand)) { var dt = new DataTable("tariff"); ad.Fill(dt); currentTariffData.AddRange(from DataRow row in dt.Rows select new Classes.TariffData { Id = int.Parse(row["Id"].ToString()), Code = row["Code"].ToString(), Description = row["Description"].ToString(), Unit = row["unit"].ToString(), Rate = row["rate"].ToString(), Rate3 = row["rate3"].ToString() }); return currentTariffData; } } } }
Class is as follows
public class TariffData { public int Id { get; set; } public string Code { get; set; } public string Description { get; set; } public string Unit { get; set; } public string Rate { get; set; } public string Rate3 { get; set; } }
If i Limit the number of data by using const string query = "select top 300 a.ID,a.Code,a.Description. The Service works fine. But if I remove the top 300 part I get an error.

I have a web service that has a CreateReport method that generates a report based on the specified criteria.
When I call this method Synchronously using a Windows Application or Console Application, the call works fine and the report is created.
When I call this method ASynchronously (CreateReportASync) using Windows Application the report is created.
When I call this method ASynchronously (CreateReportASync) using Console Application the web service does not even get the call.
I am using VS2005 and .Net Framework 2.0. So the proxy is automatically created with the Async methods. I am not really interested the result of the method call, so I do not add a Callback Delegate.

View 2 RepliesA customer reported that our asmx web service is continually increasing in memory (mem usage as well as private bytes). We are able to reproduce the problem in our lab with Windows 2003 Server SP2 (fully patched) on some of the machines. The customer is using Windows 2008.
We created a Hello World web service targeting the 2.0 framework built under VS2005 SP1 and a test client that continues to call it. The memory increases steadily - approximately 40K per client request. If the test app is paused, the memory remains the same. When it is closed, the memory drops. Explicit calling of GC.Collect does not drop the memory.
We have run the memory profiler on the service and the leak is all native memory. We have uninstalled/re-installed the Framework on one of the machines but no difference. To our knowledge all of the security and IIS settings are not modified. We have compared app pool, default web site and virtual directory properties to machines that have no problem and they are identical.
I have a .net app developed in .net 4.0 version. And I implemented an asmx web service in this. Now I want to call one of the webservice method in another classis ASP application java script function.
