display a record count from sql database connection


sometimes learning asp.net feels so heavy handed compared to some of the general purpose scripting languages like php.  for examples, all i want to do is create a sql connection that pulls a row count and displays that number.  I don't need a grid, list, detail page, etc., nothing this heavy... a simply query that will display a simple bit of text.  for the life of me I can't figure out how to do it.  Using these controls, I'm not in the code behind with the query, so I wouldn't attach this to a label (or would i), and there's nothing i see in the toolbox that does what i want.  Perhaps i'm too accustomed to php but it feels like with asp.net, major things are simple, and simple things are hard.  any help would be appreciated.  i'm trying to convert my career to c#.net

HELP: Creating an ActionResult method to display a particular database record using Entity Framework


Hi All,

I have an ActionResult method that displays records from a database table (below):

namespace STD.Controllers
    public class StudentController: Controller
        StudentEntities stud;
        public StudentController()
        stud= new StudentEntities ();


        public ActionResult Index()
            ViewData.Model = stud.StudentTable.ToList();
            return View();


I want to design a method "ActionResult Student()" that accepts "Student ID" as a parameter and displays record for that particular student only.

What do I need to do to make this happen? Could anyone please help me with this?

Thanks in advance


GridView inline Master/Detail record display

This code drop is part of a smash and grab series. If you're in a rush, you can just grab this code and insert it into your application, no understanding is required. When you have some time (ya, right) you may want to review the source code.

So thank you for all your help so far, So I think i got this right,
but would like for you all to look it over to see if there is any
areas I might run into trouble with:

//using asp.net mvc 2
the table (sql server 2005, using entities framework)
table fields
"Pattern_Media_GUID  uniqueid 
"Pattern_GUID  uniqueid
"Media varbinary(max)  
"height int
"Width int

the form:

<% Html.EnableClientValidation(); %>
<% Html.BeginForm("AddMedia", "Pattern", new { id= Model.Pattern_Guid} , FormMethod.Post, new {enctype = "multipart/form-data"}); %>

Can this code be setup to run against the whole database instead of just 1 record at a time?


We have made some changes to this code to start capturing 1 new field of data and updating it as new records are added. But there is currently about 120,000 records more or less.. those records of course dont have the new field populated with anything..

We would like to run this logic that already in place and run it against the tables to update the fields 1 time. I think to make it easier, if it can be setup to expect the "valueTwo" variable, so that we can run it againt the individual codes instead of doing all the records at one time.. there are codes that only have a few records, so it would be best to test initially against the small code group.


            strSqual = "insert into trans (trans_type_name, trans_date,sys_id,mod_user_id,show_ind, remoteCode, techName) values('" & valueTwo & "','" & TransDate & "',"&strSystemID&", 1,'T', '" & dbQuote(strUser) & "', '" & strTechName & "')"        
            'get the new transaction_id out for just inserted alarm   
            strSqual = "select max(transaction_id) as transaction_id from trans"  
            set rst = getStaticRecordSet(strSqual)

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


How to display a count of search results with keywords in a label?


Sorry for a basic post here; I am very new to VB!

I am currently building a search page, which includes a textbox and two drop-down lists, a search button, and a datagrid. If results are found and displayed, I would like a label to display:

(e.g.) "24 results found for 'blue sky clouds' "

...where the integer represents the results count, and the keywords and/or drop-down list selections are included in the string.

If no results are found I would like the label to display:

(e.g.) "No results were found that match your selection. Please try again"

I would also like the label to be invisible until a search occurs.

Thanks in advance!

Passing Primary Key to User Control to Display Record Detail


I'm building a user control to display detail information on a parent record. The user control will be displayed via an Ajax Modal Popup. The user control works and is displayed when expected. The problem that I'm having is that I'm not able to pass in the primary key for the parent. The control is displayed via the _ItemCommand event of a Repeater. In the markup for the user control, I explicity set the ContactId to 0 to avoid an error when the control loads (its still underdevelopment, eventually that I'll check if the value is valid).

I was assuming that I could change the property in the _ItemCommand event, but obviously its not working.

In the Page_Load event this code successfully sets the ContactId property of the control. The _ItemCommand event appears to set the value. However when I set a test label on the user control to the Me.ContactId, its showing '0' as if it was never passed in.

        UserControlContactDetail.ContactId = "1462"
        test.Text = UserControlContactDetail.ContactId

    Protected Sub RepeaterDirectory_ItemCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.RepeaterCommandEventArgs) Handles RepeaterDirectory.ItemCommand

Protected Sub RepeaterDirectory_ItemCommand(By

How to check if record is added in access database



I'm trying to put a registration page together in Visual Web Designer.

I would like to send a confirmation Email after someone is leaving his registration data and pressing the INSERT button.

Again, I need help to:
