If you have secure smtp server, you need to use NetworkCredentials to login before you send a mail.
Is the error related to Authentication failure?

i want to use three tier architecture in asp.net with c#.net, using ado.net
|
|
|
|

There is plenty of help available if you search google. Here is in brief what you will have:
1. UI layer having your pages and user controls.
2. Business Layer having your rules/business validations etc.
3. Data Access Layer which would perform the database operations.

There Tier Architecture is nothing but breaking your application in different layer like,
1. UI Layer
2. BLL : Business Logic Layer
3. DAL : Data Access Layer
Here is one good article for begineers :

Handle the CheckChanged event and the text for the textbox/label in that.

hiii on which command shud i do this.....can u tell me in brief....
|

This is how you cna assign the check changed event handler for the check box:
<asp:CheckBox ID="myCheckBox" runat="server" OnCheckedChanged="CheckChangedHandler"/>
Now, in the code behind, you can access your hidden field to the selected row index and then access it using the Items property.

Recently I have created a data access layer and business logic layer in a class library (seperate assemblies). I cannot get the edit or delete functionailty to work, the gridview simply posts back leaving the data intact.
I then created a dataset in the app_code portion of my web site and it works fine.
Any idea why it seems like putting this code into its own assembly doesn't work when deleting and editing (but select works fine)?

Hi,
I am a new user to ASP.NET and VS.NET and I need some help. I am also a new user to CodeProject as well.
I am trying to find a simple way to add a hit counter on a web page (ASP.NET and VB.NET) in VS.NET 2005.
I found this example "Fast ASP.NET Hit Counter with Full Digit Graphic File Support" By JediBaron.
I tried it but something goes wrong. I get this error on line 59:
Dim i As System.Drawing.Image = System.Drawing.Image.FromFile(Server.MapPath(Request("src")))
I really cannot figure out what is wrong and how to correct the problem. Any help will be appreciated.
Thanks.

This is off the top of my head.
In your global.asax do this
Sub Application_Start(ByVal sender AsObject, ByVal e As EventArgs)
Application("Hits") = 0
EndSub
Sub Session_Start(ByVal sender AsObject, ByVal e As EventArgs)
'Lock the Application for concurrency issues
Application.Lock()
'Increment the counter
Application("Hits") = Application("Hits") + 1
'Unlock the Application
Application.UnLock()
EndSub
Than put this in your web form
<%=application("Hits")%>
times.

Also he needs to store the hit count in permanent storage, so that even if the application gets restarted, the value Remains..

Hi Abhishek Sur,
I do want to store the counter hits number in a data store, but cannot figure out how to do it.
I have created a test database (DbTest) in SQL Server 2005 with a Param table and a simple column, NbHits. I can connect to it and display the number on a page. That is it.
I would like my counter to be incremented every time a user visits the main page.
I would also like to know which way is best for a simple personal web site.
Do you know of some links where I could find some example?
Thanks.

Hi HarrissonB,
This is a great start, but the counter gets reinitialized to 0 every time. There must be a simple way to store it somewhere and read the value from this data source.
Now, I suppose there are many ways to store such a value, in a database (SQL Server, Access, etc.), in a text file or XLM file, and maybe some others.
For a simple personal web site, what would be the best way (KISS method)?
In a text file, would it be safe?
Thanks.
