Hello Everybody, How can we create a class using ComClass Template. First of all, I am not able to add the reference of Microsoft.Build.Tasks.V3.5 since it is not being listed out in the Add Reference dialog. So I browsed this dll and added the reference. Still my problem is not solved. I am getting the following error. 'Microsoft.Build.Tasks.Deployment.ManifestUtilities.ComClass' is not an attribute class I am not sure. Here is my code,

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.Build.Tasks.Deployment.ManifestUtilities;

namespace COMArray
{
[ComClass(ComClass2.ClassId, ComClass2.InterfaceId, ComClass2.EventsId)]

public class ComClass2
{
    

    #region "COM GUIDs"
    // These GUIDs provide the COM identity for this class 
    // and its COM interfaces. If you change them, existing 
    // clients will no longer be able to access the class. 
    public const string ClassId = "83a8275f-9282-4257-ba62-afab6ed03beb";

    private int \_test;
    public int test
    {
        get { return \_test; }
        set { \_test = value; }
    }

}

Hello everybody, I hope someone can help me... My .net code goes like this...

public class ProxyFacade : BaseProxyFacade

{

ProxyConfiguration _configuration = new ProxyConfiguration();

public ProxyFacade(Uri Uri)

{

_configuration.Url = Uri;

}

public Student IncreaseAge(Student StudObj)

{

StudentServiceClient client;

base.ProxyConfiguration = _configuration;

base.PreProceedHandler();

client = new StudentServiceClient(base.BaseProxy, base.BaseProxy.EndPointAddress);

client.Open();

return client.IncreaseAge(StudObj);

}

}

My Issue: I have registered this dll as COM component. When I try to instantiate this ProxyFacade from VB6, I am not able to give the object reference with New Keyword? Do I have to set anything in the .net side? What is the correct way to instantiate this .net object registered as COM? My VB6 code:

Private Sub cmd_CallCOM_Click()
Dim objStud As New ProxyLibrary.Student
Dim a As Integer
objStud.Age = 11
objStud.Name = "Johnie"
objStud.IsOutStanding = False
Dim objFacade As ProxyLibrary.StudentServiceClient
Dim b As ProxyFacade

'a = objFacade.IncreaseAge()
'Set objFacade = GetObject("http://localhost:3507/StudentException/Student Service.svc/rest")
lbl_Age.Caption = objFacade.IncreaseAge(objStud).Age
End Sub

When i tried with GetObject, again error... I think i am taking a wrong way to instantiate this object which has parameterized constructor... Any help plssssssssss Tnx in advance, Saran

Hello Everybody, I want to add some http headers to my request to service from WCF client. After some google around, I found the code snippet at http://www.west-wind.com/WebLog/posts/177835.aspx\[[^](http://www.west-wind.com/WebLog/posts/177835.aspx "New Window")]">and followed it. But, It throws a generic exception that the Underlying connection is closed. No inner messages. I couldnt find out where I am going wrong... My code looks like this...

HttpRequestMessageProperty httpRequestProperty = new HttpRequestMessageProperty();
httpRequestProperty.Method = "POST";
httpRequestProperty.SuppressEntityBody = true;
httpRequestProperty.Headers.Add("testdata", "My Header");

        using (OperationContextScope scope = new OperationContextScope(client.InnerChannel))
        {
            OperationContext.Current.OutgoingMessageProperties.Add(HttpRequestMessageProperty.Name,httpRequestProperty);
            Response.Write(client.ChangeOutStanding(stud).IsOutStanding);
        }

Breaking my head since morning... Couldnt find out the reason... Any help is appreciated... Thanks, Saran

in my system, SQL Server 2000 and SQL Server 2005 are there. But I couldnt connect to SQL Server 2000. Does anybody know why and how can i resolve this?? Thanks, Saran

Hello Everybody... I have a web application developed in .net 2.0 which uses SQL Server 2005 as its backend. No error is thrown when I jus debug from my machine. But When I host it in IIS it is throwing the error mentioned in subject line. My connenction string in web.config file just has, server, database attributes along with integrated security is set to true... And the SQL Server is in Mixed Mode authentication. Still I face the error. PS: I could successfully browse the site if i mention some SQL Authenticated User id and password in connection string instead of integrated security... Is there anyother way without giving the sql userid? Why do we have to have the sql authenticated user? -Saran

Then what is the use of [EditorBrowsable(EditorBrowsableState.Never)] attribute... The description given in MSDN is -Saran

Yes... Replicated the same in my class too... But I am seeing the prorty displayed in intellisens regardless of [EditorBrowsable(EditorBrowsableState.Never)] attribute's presence.

Hello Everybody, I have a class. I dont want a particular public class member/method to be listed in intellisense property. I have tried [EditorBrowsable(EditorBrowsableState.Never)] attribute. But for this, i have to have a property. And that member is now anyway displayed as property in intellisense. I dont see any difference even after commenting [EditorBrowsable(EditorBrowsableState.Never)] attribute. Can anybody explain me how this [EditorBrowsable(EditorBrowsableState.Never)] works? What is the exact purpose? Thanks for your response... -Saran

My application will be used by internal users and also users from outside. So, I cant use windows authentication. And the requirement is to use ISAPI Authentication. Any idea on how to implement this?

There is no "upgrade" from 1.1 to 2.0. When you install 2.0 on a system that already has 1.1, they will both be available side byte side.

So, do you mean when we install .net framework 2.0, there will be 2 instances. One with 1.1(which exist already) and another instance with 2.0 version? Can I take your explanation in this way?

Thank you Navaneeth!!!

Hi All... My friend has Visual Studio 2003 and also Visual Studio 2005 installed in her system. Whenever she has to work with VS-2003, she will change the IIS to point the .Net framework 1.1 version and switches to .Net 2.0 when she works with VS-2005 and also she is telling that she has both the framework. What I thought was, to work with both VS-2003 and 2005, it is enough to have .Net framework 2.0 and this 2.0 will have all the features supported by 1.0 and 1.1. We dont install .Net 2.0 as seperate one and only upgrade 1.1 to 2.0. So no need to change the framework. I dont understand why she changes her IIS every time. But I dont change IIS. I just work with both VS-2003 and VS-2005 at a same time. How is it possible? Wht is the concept behind this .Net Framework different versions? Am I making sense? Hope I narrated in a way you can understand. Expecting your explanations for this dbt. Thank You, Saran

Hi All, Anybody knows why main() is called as main? Why not someother names but Main()? Anticipating your responses. Thank You, -Saran
