I am trying since more than 5 days to retrieve and display an image in a web page, no success so far.1. I have a table named image, with three fields ImageID, Img_data, Img_contenttype .2. I am able to display the ImageID as a link in my page.3. On clicking the link i am going to my viewImage.aspx?img=ImageID .This far it works ok. ImageID is passing in the query string.4. In this page imageID is being captured from query string and stored in ImageIdview int variable. viewImage.aspx has an image tag to display the image as below.
i want the following in 1 div. say <div="topdiv">: i want to display on aspx page one image and its description fetched from database. i want to provide a next button at the side of it, onclick of this the next image and descriptn must be displayed without page being refreshed. i have another div (<div="divbottom"> which displays other information..
i have created a table in sql server 2005 with two fields ImgId and ImageURL,where ImgId holds the serial number and Image URL holds the URL of the image file about where it is located in my hard disk.
Now i want to retrieve images from the database using its filepath.
I think i had done everything right,I tried to retrieve images in a gridview but dont know why it doesnt shows anything when i build the code.
I am new to asp.net and working with PDF documents.
store and retrieve pdf stored in sql database display the pdf (not download) use pdf page and search parameter to navigate around the pdf document.
I have stored the the pdf uploaded as byte[FileUpload1.FileBytes] using "image" datatype in database. My problem now is to retrieve the binary data and decode to a pdf. I followed the code in the article [URL], which lets me to download a file, but when i tried to open the pdf it showed me error.
"adobe reader could not open test.pdf because it is either not a supported filetype or because the file has been damaged (for example it was sent as an email attachment and wasnt correctly decoded)"
This is a small problem that is leaving me a confused! Basically, I have a database which currently stores the physical file paths of thousands of images e.g 'D:cats3. Feline PlayObject playIMG_0593.jpg' which I want to display using asp.net/vb.net and the image control. It seems the image control will not accept the physical path to display the image so how do I go about converting this to the relative format?
The image files are stored on a separate folder outside the application directory so I believe the first step is to make the folder a virtual directory.

My storing data and uploading image to database code (Just in case)
This is probably a really simple question but I have a gridview that is linked to a table in a database. But I have an imagefile stored in one of the columns in the table. The SqlDataSource links to the table an I can see the images when I test the query. I just can't see how to show the image in the gridview. All the example on the web show how to link to an image on the server and not that is downloaded from the server.
I would like to take your help for a small task of mine. I have dataset whose contents have been converted as xml, the contents of which needs to be sent to a stored procedure. How do i go about creating methods in the data layer and the stored procedure.What should be parameter type in the data layer's method and what should be the parameter type in the stored proc. I dont want to use a varchar at the stored proc level because it is limited to a length of only 8000 characters.
I need to run a stored procedure from an aspx page but because it takes a long time to complete, it times out at MyDataAdapter.Fill. This sp doesn't return any recordset but the number of records affected would be nice.
Protected Sub BtnProcessDT_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles BtnProcessDT.Click Dim DS As DataSet Dim MyConnection As SqlConnection Dim MyDataAdapter As SqlDataAdapter MyConnection = New Global.System.Data.SqlClient.SqlConnection MyConnection.ConnectionString = System.Configuration.ConfigurationManager.ConnectionStrings("RevConnectionString").ConnectionString MyDataAdapter = New SqlDataAdapter("uspINSERTDT", MyConnection) MyDataAdapter.SelectCommand.CommandType = CommandType.StoredProcedure MyDataAdapter.SelectCommand.Parameters.Add(New SqlParameter("@RowCount", SqlDbType.Int, 4)) MyDataAdapter.SelectCommand.Parameters("@RowCount").Direction = ParameterDirection.Output DS = New DataSet() 'Create a new DataSet to hold the records. MyDataAdapter.Fill(DS, "RowCount") 'Fill the DataSet with the rows returned. Basic syntax of the stored procedure. It SELECTS a single record (at a time) from a table, processes the data and UPDATES four other tables. ALTER PROCEDURE [dbo_DHT].[uspINSERTDT] (@RowCount INT OUTPUT) AS BEGIN select @RowCount=@@ROWCOUNT END
Do I need to create a DataSet if all I want to do is capture the number of records? How do I increase the timeout? This is strictly an intranet web application used by one person so performance isn't a big priority. Editing the sp to reduce the amount of time to process isn't practical due to the amount of processing that occurs.

What ASP.NET page lifecycle event can I write code in to determine the size of the viewstate that being sent out? Also, is it possible to determine the size without parsing through the rendered HTML (like a property on the page object) or is parsing the only way?
What I'd like to do is log the sizes, specifically if they cross a certain threshold.
