Concerned about timeout issues

Posted By:      Posted Date: September 15, 2010    Points: 0   Category :Sql Server
I fixed an issue today which surprised me and so I'm looking for some insight? Environment Specs ASP.NET app using DAAB 2.0 SQL Server 2008 R2 database I had some custom code  that was getting a 'SqlException: Timeout expired' error on update when the  update value was large in size.  After investigating I found what I believe to be the problem code The code pattern is     Dim dr As IDataReader = GetCustomerSetting(SettingName)             If dr.Read Then                 UpdateCustomerSetting(SettingName, SettingValue)             Else                 .AddCustomerSetting(SettingName, SettingValue)             End If    dr.Close() The datareader is always getting either 1 or 0 records  NOTE: SettingValue is an nTEXT datatype! The problem is that if the DataReader locks the database record/table then the Update is blocked. This blocking only occurs when the Settingvalue exists already (i.e. Update) and is large enough. The solution was of course to move the dr.Close() up above the Update. I personally don't like this pattern , however it used throughout the app without problem?   Any insight as to why SQL

Remoting timeout issues


Are there any known workarounds for the really annoying lengthy remoting timeouts on down servers? This is particularly a problem when using .Net remoting and the server isn't available, it can take up to 2-3 minutes for the line of code to timeout when accessing a remote object.

I have tried implementing a Ping class before I access the object, but sometimes this just doesn't work if the server is in the process of shutting down...

Obviously having an application hang for that long is unacceptable.. I am threading everything however my application will not cleanly close if the thread is hung waiting for a socket timeout.


A sample for you..

ClassExample myclass = (ClassExample)Activator.GetObject(typeof(ClassExample),"tcp://someserver:65000/RemoteObject");

if(myclass.IsAlive){    // HANGS here if remoting can't contact server for remote object.

SQL 2008 timeout


I am recently getting a timeout exception when executing this method. This table stores images and it might be due to the size of the table. I have no idea! Help!


 Public Sub StoreFile(ByVal fileId As Integer, ByVal upload As Stream, ByVal connection As SqlConnection)
            Dim bufferLen As Integer = 8040
            Dim br As BinaryReader = New BinaryReader(upload)
            Dim chunk As Byte()
            chunk = br.ReadBytes(bufferLen)

            Dim cmd As SqlCommand = _
            New SqlCommand("UPDATE tblContactDocuments SET ContractDocument=@Buffer WHERE AutoID=@FileId", _
            cmd.CommandTimeout = 30
            cmd.Parameters.AddWithValue("@FileId", fileId)
            cmd.Parameters.Add("@Buffer", SqlDbType.VarBinary, bufferLen).Value = chunk

ReadXML Timeout


I am reading an XML file from an external URL and putting it into a dataset that is the populates a repeater. This works fine when I run it locally, however on the published web site I receive A connection attempt failed because the connected party did not properly respond after a period of time error messages.

However, if i type the URL directly into a browser, I get the XML file almost immeadately which leads me to believe that I am going about this the wrong way or I need to some how to extend the timeout period.

Here is my code:

Protected Sub ButtonValidate_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ButtonValidate.Click
        If Page.IsValid = False Then
        End If

        TableCellVATSIMIDResults.Text = "<br />VATSIM ID Validation Results for <i>" & TextBoxVATSIMID.Text & "</i>"
        Dim DataSetVATSIMValidation As New DataSet
        DataSetVATSIMValidation.ReadXml("http://cert.vatsim.net/cert/vatsimnet/idstatus.php?cid=" & TextBoxVATSIMID.Text)


<asp:Repeater runat="server" ID="RepeaterVATSIMValidation">
                    <HeaderTemplate />

Versioning Issues With Optional Arguments

One nice new feature introduced in C# 4 is support for named and optional arguments . While these two features are often discussed together, they really are orthogonal concepts. Let's look at a quick example of these two concepts at work. Suppose we have a class with one method having the following signature. // v1 public static void Redirect( string url, string protocol = "http" ); This hypothetical library contains a single method that takes in two parameters, a required string url and an optional string protocol . The following shows the six possible ways this method can be called. HttpHelpers.Redirect( "http://haacked.com/" ); HttpHelpers.Redirect(url: "http://haacked.com/" ); HttpHelpers.Redirect( "http...(read more)

Issues with Visual Studio 2010 editor


hi all,

I am having a weird problem with VS 2010. I am using the premium edition.

It seems that none of the asp controls <asp:..> tag are recognized by the editor. I keep getting a green underline under each control name. To check this, I have created a brand new web site targeting .NET framework 4.0 and even in the auto-generated pages, none of the asp controls is recognized. I am also unable to see the properties of any control if I click inside the tag (at an attribute). All I get is the ID of the button and the tag <HTML ELEMENT>! Furthermore, when I drop an ASP control from the toolbox, the attribute "ID" is not generated. Only when I switch to the design view that I can get to see the properties of the control and the ID is set automatically. The message for the green underline says: Element 'Button' is not a known element. This can occur if there is a compilation error in the Web Site, or the web.config file is missing.

Does anyone know what is going on?

Session Variable issues


Hello everyone,

I ran into an issud to day with the follwoing code.  The strPanelOrder session variable is false, however, once it goes into the next if statement and sets the strTrimOrder to True, it changes the strPanelOrder session varialbe to true as well.  Why is this and how to I stop that from happening?

If Session(strPanelOrder) Is "False" Then
                If (strItemNumber.Length() = 10) And (strItemNumber.Substring(0, 2) = "FS" Or strItemNumber.Substring(0, 2) = "FC" Or strItemNumber.Substring(0, 2) = "DS" Or strItemNumber.Substring(0, 2) = "DC") Then
                    Session(strPanelOrder) = "True"
                End If
End If
If Session(strTrimOrder) Is "False" Then
               If (strItemNumber.Substring(4, 1) = "T") And (strItemNumber.Substring(0, 2) <> "AC") And (strItemNumber <> "Length") Then
                    Session(strTrimOrder) = "True"
                End If
End If


Thanks in advance for taking a look at this.



Session issues with IE8



I am trying to invoke a window using the following commands:

Response.Write("<script>" & vbCrLf)"

Response.Write(window.open('" & url & "','','toolbar=0,status=1,resizable=1,scrollbars=1,menubar=1');" & vbCrLf)"


The problem however is that on IE8 the session object is not carried over to this new window. I get "Nullpointerexception" when I try to retrieve the connection object from the session. It works on IE6 though.

Any help would be greatly appreciated.


Migrating aspnet tables to dev server - having issues



We're trying to migrate a one of our apps to our dev server for testing and development, but we're having problems with the membership functionality. We can add users, but there seems to be a disconnect with roles. We can query the aspnet_users table and find the new user in there, but when we query the aspnet_usersinroles table, that user id is not present.

We're also unable to run the Roles.GetUsersInRole("somerole") method. It returns 0 records. When I run Roles.ApplicationName, it returns the correct name, so .NET should be passing the correct app name.

We're just a little baffled. If anyone could shed some light on what could be the issue, we would appreciate it.

Thanks! :)

Trying to get Roles to populate a checkboxlist based on tutorial and having issues.


I have been using the following tutorial and had to convert the code to C# for my project, now i cant get the code to work, im getting red line under the word "in" in the UpdateRolesFromList,
i tried to add a datasource on page load for the checkboxlist like so RoleList.DataSource = PopulateRoleList(User.Identity.Name.ToString());

and gives me error saying cannot implictly convert type 'void' to 'object'


What am i missing, that when i load the page or even do a search it never displays the checkbox list as it shows in the tutorial?

        protected void Page_Load(object sender, EventArgs e)

        public void PopulateRoleList(string userName)
            string[] roleNames = null;
            string roleName = null;
            roleNames = Roles.GetAllRoles();
            foreach (string roleName_loopVariable in roleNames)
                roleName = r
