Issue with Proxy code when generated for WCF service



There is an issue I am going through when generating Proxy code for my WCF services. Whenever I generate Proxy code for services with methods having VALUE Type parameters, additional BOOL parameter <parameter>Specified is added to the generate Proxy Code.

So if I have method - Employee GetEmployee(int Id), the respective proxy code for this method will be - Employee GetEmployee(int Id, bool IdSpecified).

Moreover, if you do not set this bool parameter value to TRUE, no value will be passed to the End service.

I can understand this can come handy when handling Null inputs, but that will not be always the case.

After doing some R&D, I found that if I add Data Format attribute of type RPC to my Method contract, these parameters are removed. Like if I add: 

[DataContractFormat(Style = OperationFormatStyle.Rpc)] , the generated proxy code reflects all value type parameters as is.

I am not an expert in WCF, and for the same reason I don't have much idea on what significance this attribute plays for the service methods. Can adding this attribute introduce problems when consuming these methods by application in .NET 1.1 or in JAVA?


Can anyone help me in getting ride of this additional parameter in the proxy?

Thanks in Advance.




IsapiModule Error 500 Issue


I am about exhausted trying to figure out this error:

HTTP Error 500.0 - Internal Server Error

Description: The page cannot be displayed because an internal server error has occurred.

Error Code: 0x8007007b

Notification: ExecuteRequestHandler

Module: IsapiModule

Requested URL: http://localhost:80/ReportServer

Physical Path: c:\Program Files\Microsoft SQL Server\MSSQL.2\Reporting Services\ReportServer

When I enable Failed Request Tracing Rules and view the log output I am supposing that the actual problem is in the 2nd call where there are 2 backslashes before the actual filename in the specified path:


CALL_ISAPI_EXTENSION DllName="C:\Windows\Microsoft.NET\Framework\v2.0.50727\\aspnet_isapi.dll"


MVC2 issue - Stuck. Trying to create a cms with nested partials


I am currently trying to display multiple items on a single page. I am not sure as to how to tackle this. What I have is a database table that has all the page data in. I have this run as a PagesController and this works fine. However what I would like to do is, if say the Products page is selected via the menu, I want to pull back not only the Products page html but also get all the products, and even be able to pull them through via category. I was trying to use a partial view, but I can't get it to work. The same would be for other pages, having partial views to display the other content, ie if Gallery is selected, the page html for Gallery shows and it then can push to a partial view that pulls all the gallery images from the gallery db table and so on. 

Maybe I am tackling this the wrong way. I have the pages stored in the db to allow for a CMS system I have setup. Maybe I need to use models for all the other items(Products, Gallery, Videos and such) and use the partial for the page html?

Any help would be greatly appreciated as I am confused.

deploying to msdeploy does not support a proxy server


I am trying to deploy through webmatrix but my system Proxy server configuration is not being used. I assume that webmatrix would detect the proxy server settings and use that for the msdeploy calls under the hood. Can anyone confirm this is a know issue?

User validation Issue in xlsx file

Multiple Paramatized Threading issue


I need the funcitonality to have two methods run concurrently of each other and the parent thread (aka the method that makes these two calls) to halt until BOTH are done. After the threads are done, I need to perform logic on the returns of the method, so it is essential for both of them to be complete before the parent thread continues. I have searched the internet and tried varous attacks, and I always come up with the same result, this being the parent thread continues operation after the first thread finishes, leaving the second thread running.  Can someone show me a quick example of how I can do this. I have tried checking states of the threads, halting the threads, but I always end up with the same thing. Any help would be great. Thanks.

Word Automation in sample ASP.NET(C#) application.

I am using Microsoft.Office.Inetrop.Word Assembly for automation. Here I am reading a XXX.dot template file and fill the contents with dynamic data.

When i am executing my code in localhost:someportnumber the automation is working fine and I could get expected result and when I am hosting in my inetmgr(Windows XP is my OS) it is also working fine.

But the problem is that when I am hosting in my production server(Windows Server 2008 Standard Edition) I am not able to perform automation and results in the following error.

Data: System.Collections.ListDictionaryInternal
Message: Word has encountered a problem.
Source: Microsoft Word

The code gets failed in the following line:

ApplicationClass wordApp = new Microsoft.Office.Interop.Word.ApplicationClass();

Document wordDoc = wordApp.Documents.Add(ref oTemplate, ref oFalse, ref oMissing, ref oMissing); // Error in this line

I cannot able to proceed further. Can anybody please help me in solving this issue?

Thank you.

If Statement Issue



This is very strange to me. I have spent 2hrs looking into this inside out , but dont seem to get it

I have an if statement that inserts data into the database. But i check to make sure the name is not entered twice. Now when the name is already in the db, then it should insert else put out a message saying its already in the db

My code works fine except that  when its not in the db, its inserts but still puts out the message that says "Name is already in use" Not sure if am not seeing something. But thought i did bring it to the forum. Here is my code...Pretty simple

Protected Sub btnAdd_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAdd.Click

        Dim objConnection As SqlConnection
        Dim objCommand As SqlCommand
        Dim strSQLQuery1 As String


        ' If there's nothing to Add for then don't search
        ' o/w build our SQL Query and execute it.
        If String.IsNullOrEmpty(txtAdd.Text) Or Leadbank.SelectedValue = "000" Then

ASP.NET Proxy Page - Used for Cross Domain Requests from AJAX and JavaScript

The article ASP.NET Proxy Page - Used for Cross Domain Requests from AJAX and JavaScript was added by Aamir Hasan on Thursday, August 19, 2010.

One of the pain points with developing AJAX, JavaScript, JQuery, and other client-side behaviors is that JavaScript doesn't allow for cross domain request for pulling content. For example, JavaScript code on www.johnchapman.name could not pull content

Datalist with embedded Grid or List...Sub Totals issue with iteration


Let me see if one of you can assist with this one...


i have a similar situation, but mine does not use the selected item (item Command). Here is what the form is to do:


1. this is for an educational environment, so we use SID- NOT SSN's, but i use the SID as a filter in the subset as the grouping unique id.

2. I'm trying to inject a sub total row at the last line item of each SID (if more than one item in the report for that SID).

3. I'm looping thru the items in the Datalist Item Command with a for each (item i in Datalist2.Items).
