I am reading in a file into a string. Then I am writing this string to a stream. I know this code works fine.
The only problem that I have is with the line that write the data in chunks where the parameters is not supported for the Write method.
The line that has the problem is this line. What do I need to change here?
OutPut.Write(buffer, 0, Math.Min(to_write, WRITE_CHUNK));

Suppose we want to select the data from the database then we write the query for that. Example:
SqlConnection con=new SqlConnection(Connetion name) string selectPkId = @"SELECT PK_ID FROM TABLE" SqlCommand cmd=new SqlCommand(selectPkId ,con);
So,my question is that why we basically use @ before the sql query.If I don't use @ before that then it again work fine (does not give any error), then what is need of using "@"?

View 3 RepliesI am coding a classic .asmx web service. The method get data (as a string) from a server, then assign data to an object, then return that object. But I want to cache that object to a XML file for other request. It's because the data from server is not frequently change. Thus, after some minutes, I have to refresh the XML file. When I refresh XML file, I could write object to XML first, then return that object, but that approach maybe slowly.
How can I return the object for client first, then write this to XML file?

View 2 RepliesI am using ASP.net with WebMethods to show data to the customer and save data entered by the customer.
My current framework uses javascript to create an xml with all of the values of all the html elements in de "div" (or other element). This xml is converted to a string and send to the webserver using PageMethods.
When I receive this xml (as a string), I parse it with my own XmlDataParser which does some security checks.
I need to parse the xml to an XmlDataParser in every PageMethod I use, and I also need to catch different exceptions (like exceptions that are thrown when data is validated) to show them to the user (=> The reason why is explained in one of my previous posts: [URL]
I wonder if it is possible to write a wrapper around the WebMethod, so I can parse the xml to the XmlDataParser in this wrapper, and pass it on to the code behind, and process exceptions that occur in the code behind?
I have written an Http Module that hooks onto the Response.Filter property of the current request and does various replacements within the HTML before it is sent to the client.All the work is done in the Write method which is overriding Write in the base class Stream.
The Write method is called multiple times for a single response - the HTML seems to be written to the output stream in chunks. My problem is that I don't have an efficient & reliable way of telling if the current chunk is the last chunk (for why I want to know this see below). The only way I have come up with is to check if the chunk contains a closing html tag - but this is not very efficient or reliable.
The reason this is needed is that the module must add the "Refresh" HTTP header to the response, but only if the HTML fulfills certain conditions (and there are certain conditions that mean the header must not be added). So, only when the last chunk has been seen does the code know if the header can be added or not. So, I either need a test for the last chunk, or on each call to Write I add the header if the current block of HTML passes the test (if it has not already been added) or remove the header if the current block of HTML fails the test (if it has already been added).
So, is there a better way to test for the last chuck OR is there a way to test for a particular header being in the response and delete it (there doesn't seem to be a way to do this - only to append headers)?
I want to iterate through HtmlTable (Server Side) in ASP.NET 3.5.
foreach (System.Web.UI.HtmlControls.HtmlTableRow trow in someTable)

I have just started using MVC2 in VS2010, and I noticed that on the Register page DataType.EmailAddress doesn't actually do any validation, so it does not check whether or not the Email Address entered is valid. Should I write some email validation code in the HttpPost Register method of my AccountController, or is there another way to do this?

I want to write a page where user's can write a blog post and publish it to the blog. I've downloaded blog engine .NET and looked at the code and I like the way they do it, but it's completely an overkill of what I need. What I need is only a title, author, date, and the blog post it self. I don't even want users to post comments or anything like that. My approach is to save all those blog post information into an xml and then when a page loads it loops around those xml files to show the blog post.

Since ASP.NET MVC3 RC2 I encounter a bug when posting values to a controller method of which one of the parameter is a nullable int. Steps to reproduce:
I've created a test method
[code]....
In MVC3 RC1 this was working without any problems with the nullable int
Update:
I don't seem to have the problem with a newly created MVC3 website. What could I have in my project that influence model binding to nullable int's? And why would there be a difference between RC1 and RC2?
