Return a asp:image from codebehind

Posted By:      Posted Date: October 06, 2010    Points: 0   Category :ASP.Net


I'm trying to return a image from a codebehind function, but the output is :System.Web.UI.WebControls.Image and not the image.

How to solve?


    Protected Function DisplayComment(ByVal serviceCoverageNotes As ServiceCoverageDAL.Intranet_ServiceCoveragesRow) As System.Web.UI.WebControls.Image
        Dim commentImage As New Image
        If Not serviceCoverageNotes.IsserviceCoveragesInfoNull Then
            commentImage.ImageUrl = "~/IntranetFiles/image/Icons_16/comment.png"
            commentImage.ToolTip = serviceCoverageNotes.serviceCoveragesInfo
            Return commentImage
            commentImage.ImageUrl = "~/IntranetFiles/image/Icons_16/comment_delete.png"
            commentImage.ToolTip = "Ingen information"
            Return commentImage
        End If
    End Function

Return Image as FileResult....


...causes not all the images on the page to be displayed and the alt value to be shown.

In firebug the total of the page is 760kb. this includes some images used to show rounded corners.

however, it is the images returned as a file result that do not display the first time. When I do a refresh they display due to the cache settings.

anyone know what I can do to fix this?

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

ASP.Net Upload Image to MS Access Database

As you learnt from the previous articles to upload image to the SQL Database in ASP.Net 2.0 and stream that image into the memory to retrieve it from the database and display it on the web page. In this article you will learn how to upload images to the MS Access database in ASP.Net 2.0

First of all create an Access Database and place it in the App_Data folder of ASP.Net web site project. Then create a table "tblImg" with the following fields:

Get pixel format, raw format, property id list and property items image in VB.net - C#.net.

n this simple article you will learn that how we can get pixel format, raw format, property id list and property items image in VB and C#.net.

Get Pixel Format:

Image consists of pixels to get the format of the pixel we have a property named pixel format. This property returns an enumeration of pixel format. This enumeration tells the pixel format.

To demonstrate make a window application. Drag one button and a picture box on form.

Now write the following code on Button click event:

ListView DataPager with SQL-Statements that already return only paged data.



As far as I understand the ListView-Control and the DataPager-Control, they work like this: The ListView gets its datarows from its data source, then the DataPager causes the ListView to display only a subset of those rows.

So what, when I want to use custom databinding for the ListView, that *already* gets the certain subset from SQL-Server (for better performance). Can I and how can I use the DataPager then?

Thanx, S.

Need Syntax To Make Results of LINQ Union Return Non-Generic Type



I have the below SQL which works just fine:

SELECT     Message, CreateDate, AccountId, AlertTypeId
FROM       dbo.Alerts
SELECT     TOP (100) PERCENT Status, CreateDate, AccountId,
                          (SELECT     10 AS Expr1) AS AlertTypeId
FROM         dbo.StatusUpdates
WHERE AccountId = PassedInParameter

I have been going about trying to convert the above into a LINQ method and am having problems with return types.
As the above SQL illustrates, I am querying two distinct LINQ tables - Alerts and StatusUpdates -
and then attempting to perform a Union on them. In order to do the union in LINQ, I have to have agreeing types. So, I
am using "var" to make the results of "alerts" and "updates" generic before the union.  

public IList GetStatusUpdatesAsAlertsByAccountId<T>(Int32 accountId)
            using (WorkbookDataContext dc = _conn.GetCont

XMLHTTP object returns the below code unexecuted.  Anybody knows what's going on?  thanks.

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
