I guess you are able to execute a select command to check if the record exists or not before inserting it into DB. If you don't know how to write it, you can get started with the starter kits[^] and tutorials[^]

Hi there. Your sample code seems not to do with the error you are currently seeing. You might also want to post the error message.

Hi, I read a tutorial about sending email from ASP.NET application using SMTP server .... I wrote the following;
SmtpMail.SmtpServer.Insert(0,"127.0.0.1");
SmtpMail.Send(TextBox1.Text, TextBox2.Text, TextBox3.Text, TextBox4.Text);
In the text boxes i am providing appropriate values while when I execute this code, I receive the following error:

hi
can you provide your total code??
thanks,
Bhasker P

Hi, well thanx for your concern but that was my total code except the header files .... and I got it right using the following;
SmtpMail.SmtpServer = "localhost";
It is not working by using "127.0.0.1" for some reason!
Thanx a lot!
|
|
|
|

setting the smtpserver to localhost or 127.0.0.1 wont work for this.
you must have a configured SMTP server in your sysstem.
for us the SMTP server is "hlssrvdcmer008"
below is code for sending mail. check it.
System.Web.Mail.MailMessage msg = new System.Web.Mail.MailMessage();<br />
msg.Subject=Sub;<br />
msg.BodyFormat=System.Web.Mail.MailFormat.Text;<br />
msg.Body=bodyText;<br />
msg.To=mailTo;<br />
msg.From=mailFrom<br />
System.Web.Mail.SmtpMail.SmtpServer= "hlssrvdcmer008"<br />
System.Web.Mail.SmtpMail.Send(msg);
where variables Sub,bodyText, mailTo and mailFrom should be set with apprpriate values.
first of all find out your SMTP server name(if any);
hope this helps you
cheers

Hi,
I am using File Upload Control, and i want to place the file in APP_Code folder.
I have made the solution in InetPub-> WWWRoot.
But when i try to upload the file it gives a security error.
What i want is that anyone who wants to upload the file in this folder can upload the file regardless of the Rights he have.
I am using WIn 2k and iis5.
Thanks in Adv.

You can't do that. You must grant the rights to do this. I might add that this sounds like a very stupid idea and a sure fire way to compromise your server. Security exists for a purpose.

 Umm.. why oh why would you want to even think about doing something like this?
Give anyone, the ability to run arbitrary code on your system..
it's like.. giving the keys to the corvette to the teenager for flunking his driving test..

How do I get my session state to timeout out at a small interval (for testing purposes)? I tried adding <sessionstate timeout="3"> to my web.config file, but the session does not timeout after 3 minutes. I'm still sitting here 20 minutes later with a fully usable session state.
Any ideas? Thanks in advance.

Hi all,
I would really appreciate your help on the following... I am very new to ASP 1.1, been using 2.0, but have to do some edits to asp 1.1 files.
I get the following error when binding my dataset to a datagrid:
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.
Line 23: dgMembers.DataSource = dsMembers
Here is my code:

Make sure that the datagrid control declared in the web page .aspx with the ID dgMembers, also in code-behind the variable dgMembers is normally declared with the sample code:
Protected WithEvents dgMembers As System.Web.UI.WebControls.DataGrid

I love the ASP.NET 2.0 feature which allows one to put the connectionString nodes in the machine.config, but does anyone know how to get those connection strings to show up in the Visual Studio 2005 IDE similar to the way the ones in the local web.config show up? For example, when dragging a SQLDataSource object into the designer, the first step is to configure the datasource, which of course requires that you specify a connection string. The ones that are inherited from machine.config will work, but they aren't available to choose from in the dropdowns of the IDE.
Thanks for you help!
