Image generation best paratices for e-commerce store

Posted By:      Posted Date: April 10, 2011    Points: 0   Category :ASP.Net

I have an e-commerce store with over 1000 products and would like each product to dynamically generate about 5 thumbnails of different sizes. This way staff only need to save one big image and asp.net can generate all the other sizes.

I am wondering what is best practice for dynamically generating this many images. I was thinking dynamically creating them on every page or caching them would be too much. So instead I was thinking I could generate the image once only and save it as a file on the server which would be linked to on future requests. Then images would only be re-generated when a product image is changed.

Does this sound a good way or doing this, or are there better ways?

Visual Studio Add-In for Web Parts Generation

This article will introduce you to a new Visual Studio 2005/2008 add-in that can be used for Web Parts generation based on a prepared ASCX control/template. The add-in should allow Web Part developers to easily make Web Parts using the Visual Studio HTML designer. It should save you a lot of time and make Web Part development an enjoying experience even for beginners.

This article is written in the form of a step-by-step tutorial. It will give beginners a chance to successfully make, deploy, and try their first Web Parts, and will save some time for advanced users as you can always run into challenges when working with SharePoint.

Built-in Functions - Text and Image Functions in SQL Server

Text and image functions operate on TEXT, NTEXT and IMAGE data types. These data types are deprecated with SQL Server 2005 and should be replaced by VARCHAR(MAX), NVARCHAR(MAX) and VARBINARY(MAX) when possible. Alternatively you can also consider storing large string values using XML data type. Text and image functions are nondeterministic.

Future versions of SQL Server will not support TEXT, NTEXT and IMAGE data types. Columns with TEXT / NTEXT data type do not support commonly used string functions such as LEN, LEFT, RIGHT, etc. Furthermore, due to the large size of TEXT data you''re likely to see performance issues if you store such data in the database. However, at times you can''t help but use the TEXT / NTEXT / IMAGE data types (for example when supporting 3rd party databases when you cannot change the schema) - this is when text and image functions come in handy.

Program for Format Conversion of An Image

.NET provides extensive support for image conversion. Any image can be processed from one format to another. Most common formats to which .NET have support for are .BMP, .EMF, .GIF, .ICO, .JPG, .PNG, .TIF and .WMF.

Configuring Profile Image Export in SharePoint 2010

It's no secret that I am thrilled with the new social features of SharePoint 2010. I am most excited about the new Profile Picture handling. I strongly believe that the more we can show the faces of our colleagues to one another the more connected we will feel. Clearly Microsoft feels that way as witnessed by the many features that make use of the Profile Image like the Activity Feed and Colleagues list

How to store more than 4k bytes of data in SQL CE 4?


I need to store more than 4k of bytes in my SQLCE 4 database. How can I do that with the ASP.NET Web Pages 1.0?

1: The Microsoft.Data provider fails when I try to populate a parameter with more than 4k bytes.
2: Referencing SqlServerCe assembly and using SqlCeConnection/SqlCeCommand/SqlCeParameter throws exception:  SQL Server Compact is not intended for ASP.NET development.

How can I somehow map the generic DbType, which does not have NText as an option, to the ntext column in my database? (SqlCeParameter supports DbSqlType, which has ntext, but see problem #2)

Can't display an image from the database



My database has a products table that has images stored in a varbinary(MAX) column.

I'm trying to display product information in a repeater and trying to display the images as well by using a GenericHandler class but I can't get the image to show up in my page.

Here is my Handler.ashx class:

Public Class Handler
    Implements System.Web.IHttpHandler

    Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest

        '== Set up the response settings
        context.Response.ContentType = "image/gif"
        context.Response.BufferOutput = False

        Dim id As Integer = -1
        Dim stream As Stream = Nothing
        If Not String.IsNullOrEmpty(context.Request.QueryString("id")) Then
            id = context.Request.QueryString("id")
            stream = GetImage(id)
        End If

        Const buffersize As Integer = 1024 * 16
        Dim buffer(buffersize) As Byte
        'byte[] buffer = new byte[buffersize];
        Dim count As Integer = stream.Read(buffer, 0, buffersize)

        While count > 0
            context.Response.OutputStream.Write(buffer, 0, count)
            count = stream.Read(buffer, 0, buffersize)
        End While

Store and display Japanese characters



Can anyone tell me the best way of storing Japanese characters through ASP.NET.
I have to put characters into a asp:textbox on one page, which saves it to an Access DB.
On a second page I want to display the content in a asp:label.

Should I store the characters directly to the database or should they be encoded, and
how do I encode the characters? 

In my web.config i have:

<globalization fileEncoding="ISO-2022-JP" requestEncoding="ISO-2022-JP" responseEncoding="ISO-2022-JP" culture="ja-JP" uiCulture="ja-JP" />  

On the display page I have:

<meta HTTP-EQUIV="Content-Type" CONTENT="text/html;CHARSET=shift_jis">
