Sending Mail Using .NET

Hi ,
I have scanning thru on topics of sending mails using
.NET. I have tried the below code for sending mails .
This issue is that mails cannot be sent.

Dim mail As New MailMessage()
mail.To = ""
mail.From = ""
mail.BodyFormat = MailFormat.Text
mail.Subject = "Subject of this Email"
mail.Body = "Body of this message."
SmtpMail.SmtpServer = "localhost"


Also no error is displayed but mail is nor sent

1) This code is run on my home PC Win2k server
would the above code be able to send mails using the
local SMTP server on my machine Or does it require
a dedicated Exchange Server setup.

Help with a dataview grid   (319 Views)
I'm not sure what all is needed but this is the code behind the design view for this page. Basically it works however when I start up the page instead of the dataview grid being empty until I run a customer ID, it instead shows the numbers 27,28,29 through 43. Then when I run my customerID number it still shows those numbers yet it also shows what it is supposed to below those numbers. I can't figure out where in the world these numbers are coming from when I run the page.

Custom membership provider   (256 Views)
using vs 2005 and used the following article as a reference for creating a custom membership provider: implementation is a bit different, its using an sql database with a slightly different schema. But, it does function. It also authenticates users correctly except that any LoginStatus controls I use do not seem to notice that the user is authenticated. Logging in seems to work as in it gives me an error when I use an invalid login, and it continues on to the destinationUrl when I provide a valid login. Has anyone implemented a custom membership provider or have any idea why the loginstatus control would not be recognizing that I am logged i

HiI am new to .ASP net and have downloaded all i can and I am using MS Visual Web developer expresss 2010. I am following some training notes which is showing me how to add a controller but it doesnt seem to work.This is what the training notes tell me to doThis will create a new file, HomeController.cs, with the following code:using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.Mvc;namespace MvcMusicStore.Controllers{public class HomeController : ControllerMVC Music Store Tutorial v2.0 Tutorial under Creative Commons Attribution 3.0 LicensePage 14{//// GET: /Home/public ActionResult Index(){return View();}}}To start as simply as possible, let's replace the Index method with a simple method that just returns a string. We'll make two simple changes: Change the method to return a string instead of an ActionResult Change the return statement to return " from Home"The method should now look like this:public string Index(){return " from Home";}I create the Homecontroller but instead of naming it HomeController.cs it names it Homecontroller.vb.The code it creates for ma also looks different than above and I get thisNamespace MvcMusicStore Public Class HomeController Inherits System.Web.Mvc.Controller ' ' GET: /Home Function Index() As ActionResult Return View() End Function End ClassEnd NamespaceI have tried to change the programming and the function now looks like Function Index() As String{ return " from Home";} End FunctionI then get build errorsCan someone advise why iget .VB and not .CS and why my script is different and finally not working

form data validation   (329 Views)
, I am a beginner in trying to validate form data with validation controls.I read that the regular expression validator will not stop a textbox with just blanks or nothing in it from being submitted so a required field validator is needed to too. When I do this, a blank textbox shows an error message for each validator.(1) Is there a way of showing only the first error the controls find(2) If the data checking gets complicated, can programs be written in vb or c# be used for data checking instead of those validation controls(3) Would just doing (2) be better in the long run(4) When viewing the source of the aspx page I was struggling with, I saw Javascript but there is a runat="server" in the control. Is Javascript running at the server sideThankyou very much.

Populating a Textbox field based on values of drop down lists   (347 Views)
I have two drop down boxes that are populated with a database. Below that I have a text box field, which is also pulling from the same table. This text box field needs to be automatically generated based on the values selected by the user in the two drop down lists. I know I need to set the postback property to true of the second drop down box, so that when the user selects something, it can trigger the text box to generate the value. But I have no idea what to do after that.Any input would be appreciated. Thank you!

passing a file over a network & compressing   (200 Views)
My asp application makes a downstream (using asp) of a text file. Because that file can be sometimes big >1mb sometimes the downstreams fail. I was wondering if it was possible to compress the file before its sending and then descompress it in the pther side.I realize that if I zip the file, the file becomes 70% smaller than the original size. So I would like to know if is possbible to downstream a pdf file. the machines have windows installed (I think zip comes with windows). Another solution would be to create a cab file. Is it possible tooAny exampleThank you
problem with application deployment   (276 Views)
Guys, I have a weird problem here. I'm trying to deploy my Web application to another development server. I created an installer via Web Setup in .Net, and it installed successfully. However, it won't update the datagrid. The ItemDataBound function is working, but if the user clicks the update or cancel buttons, nothing happens; the page just refreshes. It works fine on the server it was built on. Any idea what's going on her

I'm trying to connect an page to an Access DB. At first I had the Access DB on the local server's C drive. Now I need to move Access to another server. I've mapped the folder where the DB was moved to network drive Z: on the server. And change the Data Source of the connection string to Z:/mydb.mdbNow it returns error: The Microsoft Jet database engine cannot open the file ''. It is already opened exclusively by another user, or you need permission to view its data. Is there another method to set this up Where I can have on one server and have ADO connections to Access DB on another server. Thank you.

ASP.NET Windows Integrated Security   (298 Views)
This is the first time I'm useing Integrated Security, and I am probably missing something silly.I have IIS set to use Integrated Security and anonymous access is disabled.My web.config file is set to: This causes the login prompt to appear when accessing the web form, and I cannot log in. I don't think that it is doing any real authentication. When I "allow" a specific user and "deny" another, anybody can get in. Does anybody know what I could be missin
Image Webservice issue   (402 Views)
,Let me explain the setup of our servers first,We have a webserver sitting outside of the firewall, which runs the company site. We also have an internal webserver for our intranet. We also have a SQL server which, as guessed, sits inside our firewall. There is also a internal file server.Our internet webserver will query the database and get the path of some scanned documents for our customers. These documents are images and sit on the file server. Then, these images will be displayed on the site for our customers.Since, the webserver is outside of the firewall, we cannot attach any shared drives. Our solution: create a webservice that sits on the intranet webserver and gets the info for the internet webserver. I was reading up on the webservices info on the net, and noticed that the output of a webservice is always in XML. Is there any way that I can return a image file using the webserviceI know that this message is long. I do apologize for the length of this message and I appreciate all your help
Deleteing a Record and Passing a Record   (321 Views)
Tek-Tips, two questions for you...So, i've got an Access database driven online application.Pretty normal pretty simple stuff. I've got a delete function working just fine, but I find that when I make a record...let's say the Primary ID key is 7...if I delete that record then create a new record the next record's ID is going to be 8. I figure this is bad since evetually, although improbable the database even only with one record in it, could be at ID 10000000000 or whatever. Should I be concerned Also. I'm trying to create a link, that when clicked on goes to a "details" page for instance. Just like on when you click on the job it sends you too a bigger page with more details and information on it. How can I pass one record to a page and load only that one recordI hope I made sens

Button Event not firing properly   (402 Views)
I seem to be having a problem that I can't figure out. I am fairly new to and am still getting my understanding down so this may be an easy answer question that I haven't been able to find an answer for.I have form which depending on which button is clicked it should either increase or decrease an integer by 1.It seems to work correctly the first time I click a button, but all subsequent clicks are either ignored or processed incorrectly.I have been trying to use the code behind method to do this, since I like it better, but I can't seem to get it to work.My code is below:WebForm3.aspx:CODE WebForm3   WebForm3.aspx.vbCODEPublic Class WebForm3 Inherits System.Web.UI.Page#Region " Web Form Designer Generated Code " 'This call is required by the Web Form Designer. Private Sub InitializeComponent() End Sub Protected WithEvents btnPrev As System.Web.UI.WebControls.Button Protected WithEvents btnNext As System.Web.UI.WebControls.Button Protected WithEvents lblCurrentValue As System.Web.UI.WebControls.Label 'NOTE: The following placeholder declaration is required by the Web Form Designer. 'Do not delete or move it. Private designerPlaceholderDeclaration As System.Object Private Sub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Init 'CODEGEN: This method call is required by the Web Form Designer 'Do not modify it using the code editor. InitializeComponent() End Sub#End Region Dim currvalue As Integer = 0 Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 'Put user code to initialize the page here End Sub Private Sub btnPrev_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPrev.Click currvalue = currvalue - 1 lblCurrentValue.Text = Convert.ToString(currvalue) End Sub Private Sub btnNext_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnNext.Click currvalue = currvalue + 1 lblCurrentValue.Text = Convert.ToString(currvalue) End SubEnd ClassAny assistance that could be provided would greatly help move my project along

Design idea/ code sample/ advice needed..   (348 Views)
Not sure if I'm on the right path here but this is what i want to do but not sure how to do it...I click on a button, go to the next page. On this page, I want to have 2 radio buttons. The RadioButton1 is the default and has for example 10 textboxes and a submit button with it.... When the Radio Button2 is clicked, i want to display another set of textboxes with a new submit button... so basically, going back and forth between the RadioButton1 and RadioButton2, displays different set of textboxes. How to go about doing this a sample code and/or just an idea on how to do it would be great.
