Re: In a loop - Web Development Discussion Boards

I am not sure either, but since it is working on the html page, you could IFrame it on a simple html page, set the border to 0 and you won't even know it is there.

Hi..

I have one gridview and displaying records on that. When the pagging indexes appear and i click on next index i get the following error

The GridView 'grdPosts' fired event PageIndexChanging which wasn't handled

could u tell me how to handle this problem....

You need to have some code that handles the grid view PageIndexChanging event, much like the error says. Google for it...

Here is a simple question for everyone but me.
The purpose of this code is to send a feedback message to me, the webmaster.
The visual basic code is written on a code behind page for the page which has the blanks to fill in to send the webmaster feedback.
The code sends the message. However, it's ina loop. The Protected Sub Button1_click procedure starts, it does the SendMail procedure with no trouble, Does the end sub and then goes back to its beginning of Protected Sub Button1_click to send the message again. How do I get out of this loop?
Thank you for your help.

Dim SenderName As String = TxtName.Text
Dim SendersEmail As String = TxtEmail.Text
Dim Subject As String = TextSubject.Text
Dim Message As String = TxtMessage.Text

SendMail(SenderName, SendersEmail, Subject, Message)

End Sub

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

End Sub

Sub SendMail(ByVal SenderName As String, ByVal SendersEmail As String, ByVal Subject As String, ByVal Message As String)

There's no loop in the code you posted. What does the sendmail function do?

Ok, there is no loop in the code in the Basic programing technical sense. On the other hand why, after doing the End Sub of the Protected Sub Button1_click, does it go back to the first statement of the Protected Sub Button1_click procedure and proceed to do it all over again?

Here is a copy of the entire code behind page Page/History.aspx.vb. When I step through, statement by statement, it jumps over the Catch statements and does Finally and its statements and then End Try and then End Sub and then jumps to Protected Sub Button1_click, does the Dims and starts the Send Mail all over again.
I use ASP 3.5, Visual Web Developer Express 2008. The four Dims are there so I could be sure I picked up the four variables from the Display page. Once I know things are working correctly,

Much thanks for your help.

You don't, by any chance, have an onclick="" defined for the button in the aspx page, as well as the handles statement in the code behind?

Yes, I have both statements. I have experimented taking one out and then the other but removing one or the other gets me "do you want to continue or do you want to see what the error is.
Taking one or the other out doesn't seem to get me down to the <asp:panel id="panelMailSent" ....="" xmlns:asp="#unknown"> statement. I've added a text box to see if I am really back from the <asp:button....> statement. I can type in the text box and when I hit the return, I'm back doing the Button1_click procedure. And that is with the handles statement saying quite obviously that the procedure is tor the Button1.Click procedure.

I had this working with system.web.mail but constantly got messages that it was an old way to do things. So I changed to the System.net.mail namespace and can't make it work. Like all programming errors, when I finally get it to work, it will be a minor change.

By the way. I appreciate your help. Eventually, it will work. Everyone but me can send mail with System.net.mail.

One other thing. I am sending the email comment to hotmail. Microsoft says, well here is a copy of the message:

Reporting-MTA: dns;hkram
Received-From-MTA: dns;hkram
Arrival-Date: Wed, 17 Dec 2008 15:18:44 -0500

Final-Recipient: rfc822;mhh112@hotmail.com
Action: failed
Status: 5.0.0
Diagnostic-Code: smtp;550 DY-001 Mail rejected by Windows Live Hotmail for policy reasons. We generally do not accept email from dynamic IP's as they are not typically used to deliver unauthenticated SMTP e-mail to an Internet mail server. http://www.spamhaus.org maintains lists of dynamic and residential IP addresses. If you are not an email/network admin please contact your E-mail/Internet Service Provider for help. Email/network admins, please visit http://postmaster.live.com for email delivery information and support

What is an ordinary Tom,Dick or Jane supposed to do with a message like that? Why can't the message say it's getting certain fields filled out so the server looks like a dynamic server. If you change a field to this value, we will accept your message. Why is that so difficult?

Again, thank you for your help. It's nice to have someone to complain to. Although you are not the proper person to complain to.

Hi,

I am facing a strange problem theses days with my websites.
Like, the database is currently saved in English Language ant display by the UI is as 'Ȅ૪eC,eCnC૪ilpi૪ʨ9 ૪pe9nC૪hSCpiC ૪K9e૪o9S૪1C૪i9૪'

Even now if some one saves the data in DB, the Junk Chars will be saved.
Now i changed the web.config and add <glbalization> tag, but the error is not resolved.

I got error when i edited the web.config and added a globalization tag:
'Parser Error Message: Recursive fallback not allowed for character \u003F'

Is this a problem with DB charset or ASP.NET settings. I am using .net 2.0 and SQL 2005

Also, i am not specifying any charset in Meta Tag.

Please help.

I am also getting this problem, did anyone get any solution for this? My ASP.NET website works fine on my local machine, but I get the same error when uploading to the host. The site was working fine and then I updated some text on ONE of the pages, now I get this error on ALL the pages. My site is in English and hosted in the UK so I don't think its a language problem for me.

Any suggestions appreciated!

hi,

The problem is not in your code. The problem is with the webserver. I don't know what is the problem, but i had a long fight with my host. According to them they have fixed it, but it is there occasionally.

The best way is to report the host regarding this at time when same is displayed on screen, only then they can diagnose. But they will never tell nature of issue.

Hi, You are right - when I reported it to the host they did fix it and just said it was a 'server issue'. So although I'm not much wiser, at least its working! Thanks for your reply. Smile | :)

Hi Friends,

I tried to insert Chinese into a html file in Apache-Tomcat server, and whenever i refresh it and check this page online through URL, it doesn't show Chinese but some unrecognized characters.

Can anyone tell me what the problems might be? Server side problem or my setting issue? Many Thanks...

What format did you save your HTML file in - it'll need to be saved in a Unicode format.

Hi folks,
this is my first message and blablablabla..., let's talk about serious stuff.
In my aspx website I'd like to insert a gallery of images using lightbox 2, http://www.lokeshdhakar.com/projects/lightbox2; at the same time I'm also using UrlRewriting. When i have UrlRewriting turned on if I try to view the images lightbox doesn't run, just I get a redirect directly to the image; to the other hand, when UrlRewriting is turned off lightbox runs very well.
Can anyone help me?
Thanks!

I've been trying to create a group of rules in .htaccess that will deny bots access to specific groups of pages in my site. Specifically, my site is a Wiki (running MediaWiki), and I would like to prevent bots from accessing any pages in the "User", "Talk" or "Special" namespaces, while allowing them to spider other pages on the site.

Below is my attempt... but it's not working. The basic approach I'm trying to use is this:
1. set an environment variable that identifies if the REQUEST_URI's that I want to exclude
2. set an environment variable that detects if the user agent is a bot
3. If both of the above environment variables are set, deny the page.

Can anyone give me a tip as to why the code below is NOT doing what I describe above?

RewriteEngine on

### Identify non-bot pages with environment variable
RewriteCond %{REQUEST_URI} ^/reference/index.php?title=User:.* [OR]
RewriteCond %{REQUEST_URI} ^/reference/index.php?title=Talk:.* [OR]
RewriteCond %{REQUEST_URI} ^/reference/index.php?title=Special:.*
RewriteRule ^.* - [E=PAGE_NO_BOT:1]

### Identify bot user agents with environment variable
RewriteCond %{HTTP_USER_AGENT} ^.*Googlebot.* [OR]
RewriteCond %{HTTP_USER_AGENT} ^.*robot.* [OR]
RewriteCond %{HTTP_USER_AGENT} ^.*Slurp.* [OR]
RewriteCond %{HTTP_USER_AGENT} ^.*Scooter.*
RewriteRule ^.* - [E=CLIENT_IS_BOT:1]

### If it is a bot AND it is looking at a non-bot page, deny
RewriteCond %{ENV:PAGE_NO_BOT} ^1$
RewriteCond %{ENV:CLIENT_IS_BOT} ^1$
RewriteRule ^.* - [F,L]
