Hello,

I am working on vb.net Desktop application. I am running a query to fetch data from database. When there are too many data rows, then it executes that query for the first time. on executing it for the second time, it gives me an error

The underlying connection was closed: An unexpected error occurred on a receive.

How can I execute that query more than once? I am using web service.

Thanks in advance.

VB

Protected Overrides Function GetWebRequest(uri As Uri) As WebRequest
	Dim myWebRequest As HttpWebRequest = DirectCast(MyBase.GetWebRequest(uri), HttpWebRequest)
	myWebRequest.KeepAlive = False
	Return myWebRequest 
End Function

Hi Shahin

Thanks for your reply.
Actually my application is desktop so there is no web.config or Http request.
there is app.config in my application.

My query returns 50k+ rows. whenever there is less count of rows application is working fine. but when large amount of rows comes at that time this type of error occurs.

Any Other solution

Thank You

Does your application is accessing directly to database?
You told that you where using web service. So you must override GetWebRequest in your webservice.
Look at this please:

Dear Shalin,
I have faced same problem in web application. I already solved it as u told. I have updated webconfig. and updated maxhttprequest value.

Now Problem is that.. I am using web service in desktop as class file...It is installed in local machine. So there is no http connection occur.

Thanks
