How do I change my asp.net script to use Session State instead of InProc?

Tim — Mon, 19 Oct 2009 15:15:12 GMT

All of our servers have State Server enabled.

To use it, you just need to edit your web.config session state section. Below is an example:

<configuration>
    <system.web>
        <sessionState mode="StateServer"
                      stateConnectionString="tcpip=127.0.0.1:42424"
                      cookieless="false"
                      timeout="20">
        </sessionState>
    </system.web>
</configuration>

How to publish asp.net project by Visual Web developer 2008 by ftp/http

Mark — Tue, 11 Aug 2009 16:59:01 GMT

You can publish your asp.net project by either ftp or http. This article will show you how to publish your asp.net project to web server using visual web developer express edition. If your web application is a Web Site rather than Project in visual web developer, you may refer to this article for publishing.

For http,
1. You will have to log in hosting control panel > site admin > install Frontpage extension to the domain/subdomain IIS entry.
2. Open Visual Web developer > Open your project > Click on "Build" on the top panel > Click on "Publish Webapplication"
3. Input the url, for example, http://webapp1.domain.com
4. Select "Only files need to run the application". If you select "all project files", it will include everything inside your project folder, which will take much longer time to publish.
5. You will see a log in prompt. Please input username and password to be the same as your control panel log in credential. It will start publishing if you have installed Frontpage Extension properly in steps 1. If it is failed, you are suggested to recalculate or reinstall Frontpage extension under hosting control panel > site admin > Frontpage
6. After publish complete, the output panel on the bottom of your visual web developer will show you successful result.

For ftp,

1. Open Visual Web developer > Open your project > Click on"Build" on the top panel > Click on "Publish Webapplication"
2. Input the ftp host, for example, ftp://webapp1.domain.com or if your site doesn't resolve to your web server IP, you will have to input ftp host with your server IP, for example, ftp://10.10.10.1.
3. Select "Only files need to run the application". If you select "allproject files", it will include everything inside your project folder,which will take much longer time to publish.
4. You will see a log in prompt. Please input your ftp account as the log in credential. Please make sure you are publishing to the right path because this will overwrite the existing files in the publish folder. Let's say if you would like to publish to site webapp1.domain.com which mapped to physical path D:\hosting\member\memberA\site1, if you are using a ftp account which root path mapped to physical path D:\hosting\memebr\memberA, in step 2, you will have to input the ftp host as ftp://webapp1.domain.com/site1. Otherwise, it will publish to wrong path and overwrite the existing files.
5. After publish complete, the output panel on the bottom of your visual web developer will show you successful result.

How to encrypt my web.config file?

Mark — Mon, 18 May 2009 11:25:39 GMT

Before encrypting your file, please make a backup copy first

Below are the basic steps to encrypt your web.config file.
1) Generate a RSA key
2) Input the generated key in your web.config
3) Encrypt your web.config
4) Export the key
5) Upload the key and the encrypted web.config to our server
6) We install the key for you.

Step 1) Generate a RSA key
To generate a RSA key, please open the command prompt and input the following command:
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis -pc "dotnetRSAkey_memberID" -exp

Replace memberID with your own member ID. You will be able to see this message:

Creating RSA Key container....
Succeeded!

It means you generated a RSA key called "dotnetRSAkey_memberID" successfully.

Step 2) Input the generated key in your web.config
Please download the web.config in your local machine first.
In step 1, we generated a RSA key called "dotnetRSAkey_memberID".
Open your web.config file and search "</configSections>". Paste the following code right after </configSections>. Remember to replace the RSA key name in your code.

Step 3) Encrypt your web.config
Assume you put your web.config file in C:\site1 of your local computer now. To encrypt the "connectionStrings" of your web.config file, please run the following command:

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis -pef "connectionStrings" C:\site1 -prov "CustomProvider"

You will see the following message:

Encrypting configuration section...
Succeeded!

Step 4) Export the key
To export the RSA key, please open the command prompt and run the following command
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis -px "dotnetRSAkey_memberID" "C:\dotnetRSAkey_memberID.xml" -pri

You will be able to see this message:

Exporting RSA key to file...
Succeeded!

In this example, your key file is exported to C:\ and filename dotnetRSAkey_memberID.xml

Step 5) Upload the key and the encrypted web.config to our server
Please upload the encrypted web.config and the RSA key (dotnetRSAkey_memberID.xml) to the corresponding folder in our server.

Step 6) We install the key for you
Finally, open a ticket and ask us to install the RSA key in our server now. Please tell us the place that you uploaded the RSA key file.

Using SQL Server for ASP.Net session state

Mark — Wed, 06 May 2009 16:41:08 GMT

Setup/use SQL Server for ASP.Net session state

This tutorial will go through steps to setup/install the session state service for ASP .Net application with custom database.
1.) Create the MSSQL Database for session state
2.) Tool to install the session state template
3.) Installation the session state service on custom database
4.) Update the web.config file
5.) Create the job to delete expired sessions

1.) Create the MSSQL Database for session state

Create MSSQL database for the session state service.
control panel -> databases -> MSSQL Admin -> Create New DB

This tutorial will go through with follow MSSQL DB info:
Database Server Address: sql999.mysite4now.com
Database name: statedemoDB_62760
Database User ID: statedemoUser_62760
Database Password: statepassword
*You should create/use your database to setup the session state service

2.) Tool to install the session state template
You can install the session state service to custom database with the installation template query:
InstallSqlStateTemplate.sql

By default, InstallSqlStateTemplate.sql located in following folders:
C:\Windows\Microsoft.NET\Framework\version_ID\

For example:
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\InstallSqlStateTemplate.sql

Copy this sql file to another location, and update the template file:
- find and replace all reserved string DatabaseNamePlaceHolder within the template
- replace this string to the database name which install the session state service, for this tutorial - statedemoDB_62760

3.) Installation the session state service on custom database
Connect the database with Microsoft SQL Server Management Studio

Currently, this database is a blank database:

Execute the InstallSqlStateTemplate.sql via the Management Studio

1 - Click "New Query"
2 - Copy and paste the contents of updated InstallSqlStateTemplate.sql as sql query
3 - "Execute" the query
4 - The result of the query execution

Query execution result:

-------------------------------------------------
Starting execution of InstallSqlStateTemplate.SQL
-------------------------------------------------

--------------------------------------------------
Note:
This file is included for backward compatibility
only. You should use aspnet_regsql.exe to install
and uninstall SQL session state.

Run 'aspnet_regsql.exe -?' for details.
--------------------------------------------------
If the job does not exist, an error from msdb.dbo.sp_delete_job is expected.
Msg 229, Level 14, State 5, Procedure sp_delete_job, Line 1
The EXECUTE permission was denied on the object 'sp_delete_job', database 'msdb', schema 'dbo'.
If the category already exists, an error from msdb.dbo.sp_add_category is expected.
Msg 229, Level 14, State 5, Procedure sp_add_category, Line 1
The EXECUTE permission was denied on the object 'sp_add_category', database 'msdb', schema 'dbo'.
Msg 229, Level 14, State 5, Procedure sp_add_job, Line 1
The EXECUTE permission was denied on the object 'sp_add_job', database 'msdb', schema 'dbo'.

--------------------------------------------------
Completed execution of InstallSqlStateTemplate.SQL
--------------------------------------------------

Normally, the core tables/stored procedures have installed on the database after execution
Above error message due to insufficient user privilege to add the scheduled job.
Which is a scheduled job to delete expired session state record of the session state database.

Execution of InstallSqlStateTemplate.sql installed session state related tables/stored procedures:

4.) Update the web.config file

Update the web.config to use the custom session state server/database:
Update/insert sessionState code:

<sessionState
        mode="SQLServer"
        allowCustomSqlDatabase="true"
        sqlConnectionString="data source=sql999.mysite4now.com;initial catalog=statedemoDB_62760;user id=statedemoUser_62760;password=statepassword"
        cookieless="false"
        timeout="20"
/>

** Use mode = SQLServer
** To use custom DB instead of default database "ASPSTATE" , need to enable option allowCustomSqlDatabase="true"
** sessionState : S is uppercase, case sensitive
** sqlConnectionString : C , S are uppercase, case sensitive

Session state record update within the table:

5.) Create the scheduled job to delete expired sessions record in the database

Refer to steps 3.)
To setup the scheduled job for the session state database,
you need to purchase the scheduled Task service via control panel:
control panel -> Site Admin -> Schedule Task

After that submit a ticket to our support team and they will give further assistance to setup the schedule job.

SELECT command denied to user 'user@'xxx.xxx.xxx.xxx' 'for table 'proc'

Mark — Sun, 12 Apr 2009 16:58:12 GMT

How to solve "This collection already contains an address with scheme http. There can be at most one address per scheme in this collection" error?

Mark — Wed, 24 Dec 2008 10:49:44 GMT

You may encounter following error when you are running WCF related script on server:

This collection already contains an address with scheme http. There can be at most one address per scheme in this collection.
Parameter name: item

It is because our IIS setting,by default, each IIS entry will hold more then one hostheader. (i.e.more then one address) It can be solved by customize your .svc file tospecific a custom ServiceHostFactory.

Let's say your entry have two hostname listed:

domain.com
www.domain.com

If you like to use "www.domain.com" asServiceHostFactory. You can now inherit from ServiceHostFactory andoverride it like follow sample:

    class CustomHostFactory : ServiceHostFactory
    {
        protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses)
        {
              CustomHost customServiceHost =
                new CustomHost(serviceType, baseAddresses[1]);
            return customServiceHost;
        }
    }

    class CustomHost : ServiceHost
    {
        public CustomHost(Type serviceType, params Uri[] baseAddresses)
            : base(serviceType, baseAddresses)
        { }
        protected override void ApplyConfiguration()
        {
            base.ApplyConfiguration();
        }
    }

If you like to use "domain.com" as ServiceHostFactory, you should replace baseAddresses[1] with baseAddresses[0].

How do I send email using asp.net 2.0

Mark — Mon, 01 Dec 2008 13:10:11 GMT

You need to:
1. use your email server as the smtp, this is usually mail.yourdomain.com
2. authenticate to the smtp server
3. make sure your "From" address is exactly the same as your login address in NetworkCredential class

Sameple code for asp.net 2.0:

<%@page Language="VB" %>
<%
Dim objMM As New System.Net.Mail.MailMessage()
Dim msg as String = "OK"

try
    ' configure your mail appearance
    objMM.To.Add("tom@recipient.com")
    objMM.From = New System.Net.Mail.MailAddress("info@sender.com")
    objMM.IsBodyHtml = False
    objMM.Subject = "asp.net 2.0 test mail"
    objMM.Body = "asp.net 2.0 test mail body"

    ' define smtp and authentication credential
    Dim smtp As New System.Net.Mail.SmtpClient()
    smtp.Host = "mail.sender.com"
    smtp.Credentials = New System.Net.NetworkCredential("info@sender.com","password")

    ' send the mail now
    smtp.Send(objMM)
catch e as exception
    msg = e.message
end try

response.write(msg)
%>
