IMAP component C# dot net

You can use a IMAP component to implement this. As explained here
http://www.codeproject.com/Messages/2504247/Re-Move-a-message-into-a-folder.aspx

The IMAP commands to accomplish it looks something like this:

UID COPY messageUID "new folder"
UID STORE messageUID +FLAGS (\Deleted)
EXPUNGE

Some popular IMAP components are:

IPWorks! IMAP Component from /n software http://www.nsoftware.com/products/component/imap.aspx
Rebex Mail for .NET - http://www.rebex.net/mail.net/tutorial-imap.aspx#folders
Chilkat IMAP .NET - http://www.chilkatsoft.com/imap-dotnet.asp
EAGetMail POP3 & IMAP4 COMPONENT 2.5 - http://www.emailarchitect.net/eagetmail/
Lumisoft - http://www.lumisoft.ee/lsWWW/Download/Downloads/Net/ (free)
xemail-net - http://xemail-net.sourceforge.net (free)

Below one i am using for my development.

Download 3 rd party component from
http://www.lesnikowski.com/mail/
it will be download as .exe . Click to install to a specific directory . Latter add mail.dll in reference by browsing to installed lib directory .

Document is available here

How can I use AJAX.NET 1.0 - System.Web.Extensions, Version=1.0.61025.0

If you got this message: "Could not load file or assembly 'System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified."

1. You must copy dll(s) to Bin folder:

AjaxControlToolkit.dll
System.Web.Extensions.dll v1.0.61025.0 or other
System.Web.Extensions.Design.dll v1.0.61025.0

and maybe

AJAXExtensionsToolbox.dll v1.0.61025.0

You may have add those tags and sections to the web.config:

2. Under the <Configuration> tag, add the following <configSections> sections:

Code:

3. Under the <system.web> tag, add the following <pages> sections:

Code:

3. Under <compilation>, <httpHandlers> and <httpModules> tags:

Code:

5. Under <Configuration> tag, add the following <system.web.extensions> and <system.webServer> sections:

Code:

<system.web.extensions>
<scripting>
<webServices>
















</webServices>

</scripting>
</system.web.extensions>
<system.webServer>
<validation validateIntegratedModeConfiguration="false"/>
<modules>
<add name="ScriptModule" preCondition="integratedMode" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
</modules>
<handlers>
<remove name="WebServiceHandlerFactory-Integrated"/>
<add name="ScriptHandlerFactory" verb="*" path="*.asmx" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
<add name="ScriptHandlerFactoryAppServices" verb="*" path="*_AppService.axd" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
<add name="ScriptResource" preCondition="integratedMode" verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
</handlers>
</system.webServer>

6. On IIS7 you must fix web.config with migrate tool or migrate web.confing to Integrated pipeline mode:

6.1 You must migrate the application configuration to work properly in Integrated mode. You can migrate the application configuration with AppCmd:

Code:

> %windir%\system32\inetsrv\Appcmd migrate config "<ApplicationPath>"

6.2 You can migrate manually by moving the custom entries in in the <system.web>/<httpModules> and <system.web>/<httpHandlers> configuration manually to the <system.webServer>/<handlers> and <system.webServer>/<modules> configuration sections, and either removing the <httpHandlers> and <httpModules> configuration OR adding the following to your application’s web.config:

Code:

<system.webServer>
<validation validateIntegratedModeConfiguration="false" />
</system.webServer>

6.3 Use Classic mode as a last resort if you cannot apply the specified workaround.

Moving to Classic mode will make your application unable to take advantage of ASP.NET improvements made possible in Integrated mode, leveraging future features from both Microsoft and third parties that may require the Integrated mode.

What is Virtual Memory?

What is Virtual Memory?

Virtual memory is simulated RAM. When you have used up all your RAM, your computer will shift data to an empty space on the hard drive. The computer swaps data to the hard disk and back to your RAM as needed. When you increase your virtual memory you are increasing the empty space that is reserved for your RAM overflow.

Also having enough available space is absolutely necessary for your virtual memory and RAM to function properly. You can increase Virtual Memory performance automatically by freeing up resources in your registry. You may want to use a Registry Cleaner. Click Here to learn more!

How to increase Virtual Memory?

In Windows XP

1.Click Start, and then click Control Panel.
2.Click Performance and Maintenance, and then click System.
3.On the Advanced tab, under Performance, click Settings.
4.On the Advanced tab, under Virtual memory, click Change.
5.Under Drive [Volume Label], click the drive that contains the paging file that you want to change.
6.Under Paging file size for selected drive, click to Custom size check box. You can enter the amount of memory you would like to reserve for Virtual memory by entering the initial and maximum size.
7.Click Set
When you are prompted to restart the computer, click Yes.
Special Note: You should choose the same amount for the initial size and maximum size. This will Stop your CPU from constantly changing the paging file.

HOT TIP: To stop your CPU from constantly changing the paging file, set the initial and maximum size to the same value. For example, 500 and 500. The value should be at least 1.5 times more than your physical RAM. If your computer has 512MB of RAM increase the virtual memory paging file to 1.5*512= 768

In Vista

1. Click Start button Picture of the Start button
2. Click Control Panel
3. Choose System and Maintenance and then click System.
4. In the left pane, click Advanced system settings.
5.On the Advanced tab, under Performance, click Settings.
6. Click the Advanced tab, and then, under Virtual memory, choose Change.
7. Click Custom to change the Initial size (MB) and Maximum size. See the hot tip above.

TRIGGER - After / Before / deleted / inserted - MS SQL

TRIGGER

There are

BEFORE (trigger)

AFTER (trigger)

In BEFORE Trigger .

There is no keyword in MS sql. Instead it defines for.

It is a default trigger

In AFTER Trigger.

There is a keyword in MS sql.i,e After.

We can get rows which are stored in temporary table by trigger.

Insert / update

Get values from inserted. ( select * from inserted) (copy of a row(s) effected).

Delete

Get values from deleted . ( select * from deleted) (copy of a row(s) effected).

During UPDATE

On Before trigger – we can get row which is not effected by a update in deleted table.

Basically we get rows from deleted table when we are maintaining log/history table.

On After trigger – we can get row which is effected by a update in inserted table.

Note : there is no updated temporary table.
