C# - An Operation Can Have Only One In Or Out Header Of A Given Type?
Feb 23, 2010
Situation: I am trying to consume a clients web service for CC authorization. They are not publishing the WSDL file on there site, but they have provided the WSDL file. I am using Visual Studio 2005 and creating a web application that consumes the web service.The only reference to this error that seems to apply is here: http://followtheheard.blogspot.com/2007/12/consuming-web-services.html. I installed WSE3.0 and configured my project to use WSE and am calling the WSE version of the web reference and I am still getting this error.

I am trying to call a webservice that requires me to authenticate and then pass the session id returned from the authenticate method to subsequent web service calls. The session id has to be passed as HTTP request header. So I tried using the following code to add the session id to a HTTP request header:
System.Collections.Specialized.NameValueCollection headers =
HttpContext.Current.Request.Headers;
Type t = headers.GetType();
//get the property
System.Reflection.PropertyInfo p = t.GetProperty("IsReadOnly",System.Reflection.BindingFlags.Instance
| System.Reflection.BindingFlags.IgnoreCase | System.Reflection.BindingFlags.NonPublic
| System.Reflection.BindingFlags.FlattenHierarchy);
//unset readonly
p.SetValue(headers, false,
null);
//add a header
headers.Add("Cookie",
"SID=" + sessionId );
The header is supposed to be called "Cookie" and the SID contains the session id. The problem is the last line in the code above gives an exception saying "Operation is not supported on this platform". I am running this code on my dev machine with with Windows XP Professional Service Pack 3 and IIS 5.1. I haven't been able to find any solution to this problem after days of searching. I also tried to deploy my web app on IIS directly but had the same error.

in my case, It is the windows service which in running the long running insert/update on a table and I need to cancel the operation from my ASP.NET application. In the above link Burnsys suggests that one should kill the Sql server session. Is that really only way and a goood practice to do this? Also, in the same poset can use SqlCommand.Cancel to cancel. However, I am not sure how can I cancel the command from the windows service from ASP.NET application.

I have a simple web site with two pages. One displays a list of files, and the other streams a file when it's clicked in the list. All was fine in production for 6 months, but now I have to move the site to Windows 2008/IIS7. I have it mostly working, but the files don't open properly (in Firefox) because my content-type header is being ignored. On the production site (IIS6) the headers are (using Fiddler):
HTTP/1.1 200 OK
Date: Tue, 09 Feb 2010 16:00:51 GMT
Server: Microsoft-IIS/6.0
X-Powered-By: ASP.NET
X-AspNet-Version: 2.0.50727
Content-Disposition: attachment; filename="myfile__foo.pdf"
Content-Length: 236841
Cache-Control: no-cache, no-store
Pragma: no-cache
Expires: -1
Content-Type: application/octet-stream
but on the test IIS7 server I get:
HTTP/1.1 200 OK
Cache-Control: private
Content-Length: 236841
Content-Type: text/html; charset=utf-8
Server: Microsoft-IIS/7.5
X-AspNet-Version: 2.0.50727
Content-Disposition: attachment; filename="myfile__foo.pdf"
Fiddler also reports a protocol violation and says "Content-length mismatch: Response Header claimed 236841 bytes, but server sent 238378 bytes."
My code looks like this:

Scenario:
I have a Gridview where I want to handle the Sorting in a custom control that I've added to the header.
I've added this control to my GridView's Header via OnRowCreate event handling. I want the Sort Expressions to persist session to session (via Webparts Personalization)
Here is what I have for adding the custom header control to the GridView Header
[Code]....
This works out well for adding the control, but I can't get anything to persist because these controls are creating initially via postback (per the event) and re-created on all subsequent postbacks. I can't add an If(!IsPostback) because the controls are initially created on the gridview's postback (well at least thats how it's acting when I put it in there) If I were to add this control via the ASP page, not via the Codebehind, I would be able to persist the control. If I try to treat it as though everything is setup correctly, and assign my custom control's controls to [Personalizable], I get a runtime error telling me that I can only have webpartzones in or before Page_init (I'm guessing this is due to when/where the
gridview hits the OnRowCreate event). If there is some fundimental logic I'm missing, or best practices that I'm moving away from,

In my ASP.Net (2.0) Web Service implementation (The implementation class derives from
System.Web.Services.WebService with WebServiceBinding confirming to WsiProfiles.BasicProfile1_1 .
The SOAP response sent out by the Service has two elements missing :
1> The XML header itself : (<?xml version="1.0">)
2> The opening and closing Envelope tags with NameSpace ("<S:Envelope xmlns:S=http://schemas.xmlsoap.org/soap/envelope/>" and "</S:Envelope>" ).
This results in "breaking" of my client unless the above mentioned headers are inserted at the client end, and my intent is to avoid bypasses at the client end as far as popssible.Is this the default behavior ?

I have a Tab Container that I would like to be able to add a star (*) at the end of the tab header text when there are NEW Users to be approved by the Site Administrator. By default meaning that is what I typed in designer mode is "Users Waiting Approval", but when I load the page I run a routine to see if there are and new users requesting access and at that point durning the page load I would like to change the tab from "Users Waiting Approval" to "Users Waiting Approval *" with the star at the end (*). How can I update this tab header text durning the page load event? Is there some javascript function I can call like set_HeaderText?

i have a gridview bound to sql datasource with template fields binding the columns. I have set the Header Style to a css class. I have 3 columns not bound to data as Add, Edit and Delete. When I set the text color to white for the header only the non bound columns go white. The bound columns are BLUE like hyperlink. Any one know a way round this. (If I set the style in the gridview the all columns are white. Want to set in external css file).

I am not sure if I have found the right forum for this one.
the problem is:
I have a .licx file in my rootfolder.
I am getting the error:
Error 53 Unable to resolve type ' <add type="TabStrip" version="7.0" />' C:inetpubwwwrootCrop_ApplicationCrop_Applicationeo_web.licx 7 Crop_Application
,which I get for all the types that are in the xml file(i just gave one of them).
A friend told me that I have to add the type .licx in the MIME type in the IIS .
The problem is that I find the MIME type, I add the extension type .licx but I do not know the MIME type for .licx

In my web application, I need to run a lot of sql queries for a specific operation. For example, first I run a select command , get results. If they fulfill my requirement, I insert some values by insert command, else I update and insert...and so on. I need to execute 8-10 commands for each specific operation. For this , I have created a <asp:Sqldatasource> in aspx page and I run queries by SqlDataSource1.Select, SqlDataSource1.InsertCommand etc. I dont think , its a right approach . Further, I need to preserve data consistency. Say my 5 commands executes successfully and then sql or something else, throws an error and 5 commands left untouched. Then, it will create me a problem. And my current logic will fail, as it works on step by step basis.

If i am having 2 dropdownlists, 3 gridview and many more databinding controls in a single form and I am binding different data to those controls, so I need to create stored procedure for every individual operation OR stored procedures are mainly use for inserting,updating or deleting.cos it is a bad habit to use inlinecode.
if I create sp for every single operation there might be a lots of sp in my databse... it is good for being a programmer or not.
