I'm having a doozy of a problem, and can't find a solution. I have a WFC Web Service installed to a pair of servers, and accessed through a load balancer. I am accessing the service from an ASP.NET client app, also via WCF. The Client is not load balanced.I'm getting an intermittant error:
(Inner Most Exception) System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond x.x.x.x:80(Middle Exception) System.Net.WebException: Unable to connect to the remote server(Outer Exception) System.ServiceModel.EndpointNotFoundException: Could not connect to http://<MYSite>/<MYApp>/<MYService>.svc.TCP error code 10060: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond x.x.x.x:80.
I can reproduce this error with about 20% reliability if I execute the exact same page request on the client from 2 browsers at the same time. When the problem occurs, the successful page request returns in about 5 seconds, and the failed page request returns in about 30 seconds.I'm guessing that there is some additional latency when the load balancer decides to switch my session to another server, and that is making some timeout setting on my client to be exceeded. I need to research this performance characteristic... any thoughtsbut its not my core question.My core question is... Exactly what setting can I tweak to increase the "period of time" the "connected party" is allows to "properly respond".This is the basicHttpBinding configuration I am using on both sides of the communication:
<basicHttpBinding>
<binding name="LongerTimeout"
sendTimeout="03:00:00"
maxReceivedMessageSize="2147483647"
maxBufferPoolSize="2147483647">
<readerQuotas maxArrayLength="2147483647" maxStringContentLength="2147483647"/>
</binding>
</basicHttpBinding>
I've seen some indication that setting the receiveTimeout value on the server may help, but I set this to 1 second in a test environment, and was unable to reproduce the problem, leads me to believe its not worth a production environment change to verify this.

I am using the codes sample from Peter through this link:http://www.eggheadcafe.com/articles/20030316.asp
to validate email address. I made some minor modification to validate user email address after the user have entered his or her email address as show below
string[] host = (address.Split('@'));
string hostname = host[1];
IPHostEntry IPhst =
Dns.Resolve(hostname);
IPEndPoint endPt =
new
IPEndPoint(IPhst.AddressList[0], 25);
Socket s =
new
Socket(endPt.AddressFamily,SocketType.Stream,
ProtocolType.Tcp);
s.Connect(endPt);
The last line of code s.Connect(endPt) generated the following error if the user email address is anything other than the company email address. I have try gmail, hotmail and they all generated the same error. Can the experts tell me how to get around the problem.
Here is the error:System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 64.4.20.174:25

I'm using SQL 2005 for my current project. My remote hosting server uses port number 4433 for my database. So my connection string is as follows data source=IPaddress,4433;initial catalog=mydb;UID=sand;PWD=sand45;
But when connecting from my local machine from .NET or from SQL Management Studion it creates an error
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.(provider: TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

I need to create an application with Forms Authentication and/or Windows Authentication. If the application is set to use mixed authentication (Forms + Windows Auth) and the user don't have a Windows user account, the login will fail and he must be redirected to a forms login page. How can I do this?
Are there any different way to provide mixed authentication?

In Visual Studio 2005 I am following the steps to add a Web Reference to a web service.hings appear to go smoothly except for an error messae I am getting. Here are thesteps I follow along with the result.1. Right click on Web References folder and select "Add Web Reference..."2. When the dialog box appears I add the web service URL into the URL dialog box.The web service methods are then displayed in the dialog box with the links to each web service and a prompt to "Start Browsing for Web Service"However in the box to the right which is labeled "Web services found at this URL", there is an error messagewhich reads:There was an error downloading 'https://stage-serv/weatherQuote/WebService/weatherQuote.asmx
The underlying connection was closed: An unexpected error occurred on asend.Authentication failed because the remote party has closed the transport stream.I don't know what is causing this problem. I can reference this same web service on a productionserver just fine, but if I attempt to access it on the stagig server I get the message Ijust talked about.I am thinking that something is not configured on the staging server correctly.

I was just after some help to put the following code into a loop. I have 6 div's with id's ImgDetails1 - ImgDetails6 and 6 buttons
with id's 1 - 6
if 1 is pushed it should hide the other divs but ensure div1 is shown. the same applies for every other
div.
I can do this the long way writing logic for each div but I am not the best with js and have failed
at each attempt to put the code in a 1 - 6 loop to hide all divs except the one selected and make sure that is shown.

I'm trying to make sure a block of code behind properly closes a connection to SQL after it's finished. But when I add the line "cmd.Connection.Close();" Visual Studio underlines "cmd" in green and says "unreachable code detected" What does that mean and how do I correct it?

This morning I found myself dealing with A SQL POOLING ERROR Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached. I did fix this with resetting my pooling and setting a pooling max =100 Anyway now Im starting to rethink how I open connections, dealing with errors and proper closing of connections Would you say this code below is a good way of opening, closing connections (even when errors occurred)
Dim Connection As SqlConnection
Dim myConn As String = (ConfigurationManager.ConnectionStrings("MyConnString").ConnectionString)
Connection = New SqlConnection(myConn)
Try
Dim DBCommand As SqlCommand
Dim dt As New DataTable()
Dim myDataSet As New DataSet
Connection.Open()
DBCommand = New SqlCommand("GetAllCategories_", Connection)
DBCommand.CommandType = CommandType.StoredProcedure
DBCommand.Parameters.Add("@HomePageID", SqlDbType.Int).Value = HiddenChosenVirtualMainID.Value
Dim mySqlAdapter As New SqlDataAdapter(DBCommand)
mySqlAdapter.Fill(dt)
SecondLevelChildDatalist.DataSource = dt
SecondLevelChildDatalist.DataBind()
Catch ex As Exception
'Error goes here
SqlConnection.ClearAllPools()
Finally
'close the connction
Connection.Close()
Connection.Dispose()
End Try

I wanted to post my problem and solution since I've gotten some good information on this board. When deploying my Visual Studio 2008 C# .NET 2.0 web application Production, I encountered some problems, which is not unusual. What was unusual is that my Crystal Reports .NET reports that use the Report Viewer control would not work; they errored out with:
note: Crystal Report works fine in dev environment....
Logon failed. Details: ADO Error Code: 0x Source: ADODB.Connection Description: Provider cannot be found. It may not be properly installed. Unable to connect: incorrect log on parameters.We are using Oracle 11g 64 bit as database. We establish crystal report database connection by two ways,
1. Microsoft OLE DB Provider for Oracle
2. Microsoft OLE DB Provider for ODBC
but we got the same error in report module when we using two methods.

I'm not sure if this belongs here since it doesn't seem to be a coding issue but...
I am having an issue with using httpwebrequest - the first time I run HttpWebRequest on a page there is a 5-10 second lag before it returns the data I am looking for. It doesn't matter from what source I am polling the lag is always there so it has nothing to do with the sites I am connecting to.
After I poll the first time as long as the page is reloaded within 1 and a half minutes afterwards the httpwebrequest response is lightning fast.
If I wait a minute and a half to 2 minutes without reloading the page the lag returns again.
I've tried everything related to tweaking the httpwebrequest settings and none have had any impact whatsoever.
If it helps I have older pages that use classic asp that behave the exact same way when returning data from external websites so it seems to me like a server issue.
What I am left with is...

I have some dynamically-changing text, which I would like to appear as a hyperlink (i.e. underlined text which changes colour as you hover the mouse over it). However, I would also like this text to behave like an asp:Button object when the user clicks on it. This is so I can add some VB.NET into the click event of the text. Does anyone know how I can do this?

Is there a way to respond to the click event generated by any button on a form?
I am trying to carry out a response.redirect( 'button id' & ".aspx"), can it be done?
i.e. If I have a webpage called "button1.aspx" how do I get the button1.click event to trigger the redirect without implicitly coding the click event for the respective button.

I have got 2 Drop Down Lists on my Form and 1 GridView. I want GridView to display the data according to selection from the Drop Down Lists.
For Example, One Drop Down List contains Names and other contains Dates. Both the Drop Down Lists can post back. So if i select a name from 1st Drop Down list, the Grid View should show all the results according to that Name. Similarly if i select the Date from the other Drop Down List , the Grid View should show the results according to the dates. But i cant figure out as how to bind Grid View to respond to 2 Drop Down List.
BTW i am binding both the Drop Down Lists and the Grid View to the DataSource Objects, which is getting data from the database.
