You should add Global.asax into your project and

just call the error page into

void Application_Error(object sender, EventArgs e)
{
// Code that runs when an unhandled error occurs

}

I have two custom metadata columns for Document Library, when ever uploading a document or creating new document in the document library, have to fill the metadata columns,

in this, my both metadata columns are choice types, when ever i select an option from the first choice based on this the second metadata column should populate values based on the selection

i mean

First metadata column having the values like
1
2
3
...
The second metadata colum should populate the values based upon the previous value selected from the first metadata column,

can any one come across with the same situations, please let me know or any suggestions.

Passing Network Credentials First

I am trying to access my linksys router's, web configuration to parse out my WAN ip address. However, I can't seem to get the Credentials to work correctly. I think the problem is that I am not passing the credentials first, and then trying to access the web pages. Here is the code I am using.

Dim request As System.Net.HttpWebRequest
Dim response As System.Net.HttpWebResponse = Nothing
Dim MyCredentialCache = New System.Net.CredentialCache
Dim ds As DataSet

Try
request = DirectCast(System.Net.WebRequest.Create("http://10.100.200.1/RouterStatus.htm"), System.Net.HttpWebRequest)
MyCredentialCache.Add(New Uri("http://10.100.200.1/RouterStatus.htm"), "Basic", New System.Net.NetworkCredential("", "thepassword", ""))
request.Timeout = 60 * 1000
response = DirectCast(request.GetResponse(), System.Net.HttpWebResponse)
ds = New DataSet()
ds.ReadXml(response.GetResponseStream())
Catch ex1 As System.Net.WebException
Debug.Print(ex1.Message)
Catch ex As Exception
Debug.Print(ex.Message)
Finally
If Not response Is Nothing Then response.Close()
End Try

I keep getting an Authentication Failed error 404 when attempting the response = directcast.....

Any help would be greatly appreciated!

The linksys router only uses a password, no username. When I access the web config pages using a browser, I always leave the username blank. Although I can use a username and the router ignores it. I have tried in the code to pass a username, but still get the 404 error.

I suspect your best bet is to have your swf redirect you to another page. ASP.NET cannot interact with your swf. I don't know if javascript can.

Double check IIS. Is it actually pushing the emails out on the internet, or is it just storing them somewhere. You'll have some folders in C:\inetpub\... somewhere for the SMTP server (if you are using the default configuration). Are your emails in there?

You could also show us your code. It might be giving a false positive.

According to Ur suggestion I applied following code. Output show Msg sent successfully. Actually never it is sent to destination. Messages are only push to C:\inetpub\mailroot\queue;
1.I think IIS can not push the emails out on the internet.How can I look on SMTP response code.
2.I want to send emails from localhost. Now I confused how it possible sending a mail from anonymous mail address like "shahdat_mbstu@yahoo.com" through localhost, bcoz there no relation between my localhost and my mail address "shahdat_mbstu@yahoo.com". ;
3. Please help me!;

public void CreateCopyMessage(string server)
{
MailAddress from = new MailAddress("shahdat_mbstu@yahoo.com", "Ben Miller");
MailAddress to = new MailAddress("shahdat45ict@yahoo.com", "Shahdat Kooras");//jane@contoso.com
MailMessage message = new MailMessage(from, to);
// message.Subject = "Using the SmtpClient class.";
message.Subject = "Using the SmtpClient class.";
message.Body = @"Using this feature, you can send an e-mail message from an application very easily.";
// Add a carbon copy recipient.
MailAddress copy = new MailAddress("Notification_List@contoso.com");
message.CC.Add(copy);
SmtpClient client = new SmtpClient(server);
// Include credentials if the server requires them.
client.Credentials=
client.Credentials = CredentialCache.DefaultNetworkCredentials;
Console.WriteLine("Sending an e-mail message to {0} by using the SMTP host {1}.",
to.Address, client.Host);

try
{
client.Send(message);
lblMessage.Text = "Message successfully sent";
}
catch (Exception ex)
{
Console.WriteLine("Exception caught in CreateCopyMessage(): {0}",

hello,
i need to create a form which will submit the content to an outer file like xxform.asp
the problem is that if i try to do it the form won't work. it will not submit itself to the file.
thats because it is nested inside a different form and/or is declared as runat=server
is there a way to make this happen?
will IFRAME work ?
i need the aspx functionability as well because i want to read info from a database and put it as part of the posted form , thats why i cant get rid of the outer form.

thanks in advance

[Asp .Net Page output caching] invalidate subset of pages on demand only

lermi13-Apr-09 11:27

13-Apr-09 11:27

Hello,

I am writing an engine for a forum. Now I have stumbled upon some problems with caching. I have a board view with multiple threads printed and each
one has a first few replies added. Now I decided I want to have caching not based on timeout but on custom action. When a user uploads some reply, only
then should the page expire from cache. It is also desirable to expire only those versions of pages that need to be expred (based on query string parameters).

let's say I have this situation:

so http://forum/index.aspx?page=1 cached
so http://forum/index.aspx?page=2 cached
so http://forum/index.aspx?page=3 cached
so http://forum/index.aspx?page=4 cached -> reply happes
so http://forum/index.aspx?page=5 cached
so http://forum/index.aspx?page=6 cached

.. pages 1 - 4 must expire from cache. The rest should stay in cache. Also I do not want any of the pages to expire from the cache before this action
for whatever reason this could happen. Please help me with this.

for now I have written in page load of index.aspx this:

1) in global.asax, Application_Start:
HttpRuntime.Cache.Insert("all", DateTime.Now);

2) and in my index.aspx page load event this:

Response.AddCacheItemDependency("all");
Response.Cache.SetCacheability(HttpCacheability.ServerAndNoCache);
Response.Cache.SetExpires(DateTime.Now.AddMinutes(5));
Response.Cache.SetValidUntilExpires(true);
//Response.Cache.VaryByParams["page"] = true;

3) then if I want to reset all pages dependend on key all, I call index.aspx with query string parameter ccreset and again
in global.asax Application_BeginRequest I check for this query string parameter and modify key all to invalidate cache like this:
HttpRuntime.Cache.Remove("all");

PROBLEMS
________

A) Even without trying to invalidate my cache, page output caching occurs only if I do not specify VaryByParams. As fast as I add this line of code:
Response.Cache.VaryByParams["page"] = true;
caching stops. I print a timestamp on the page to see this. I do not understand this. Problem is exactly the same if I use the declarative syntax inside
aspx page.

B) Let's say I forget about the VaryByParams, caching works out of the box, time stamps printed on my page confirm this. But, even when I modify the
"all" key in my cache hoping to initiate cache invalidation nothing happens. All pages remain in the cache as nothing happened. Why is that?

QUESTION
_________

I would like to understand why B) happens and also what is up with A). But please, if I should be doing this thigs some other way feel free to skip
answering me my first two questions and just explaing to me what is the easiest and most straight forward way to achieve what I want.

Thank you for your replies in advance

                </ItemTemplate>
            </asp:TemplateField>
