How To Display Image From Physical Filepath Stored In Database

Jun 14, 2010

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.

DataSource Controls :: Execute A Stored Procedure From An Aspx Page

Jan 8, 2010

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.

Determine Size Of Page's Viewstate Before Serving Page?

Oct 28, 2010

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.
