I have the above function that i'm using to send emails from an IIS hosted .NET 3.5 asp.net application.
The emails are sent at the click of a button and the recipients are being read from a database table.
The problem i'm having is that some recipients get their emails with out any issue, others take far too long to receive their emails (sometimes after 24 hours) at which time the event they are supposed to participate in has expired (and this has legal implications to my company). And then finally, others do not receive the email completely.
The above MailForCandidate function is being called from SendCandidateMail below.
private void SendCandidateMail(int intEmailType)
{
try
{
ArrayList arrPending = new ArrayList();
ArrayList arrUnsent = new ArrayList();
string strCandidatename = string.Empty;

I'm find it hard to troubleshot because it is occurring in production ONLY. In QA and Dev, emails are just going fine using the same SMTP server.
I will just post my comment here as the answer.
I resolved this bu just discarding the obsolete system.web.mail. I
re-wrote the code using System.Net.Mail & all issues are resolved,
performs even much faster.
Recently I have upgraded my project from .NET Framework 3.5 to 4.0. For WCF I am using custom basic authentication.
Before conversion, all was working fine. However, after conversion I am getting "Unexpected end of file error". The stack strace is as below :

The class and method in which I am getting error are as below :
p
ublic class BasicAuthenticationInterceptor : RequestInterceptor
{
MembershipProvider provider;
string realm;
public BasicAuthenticationInterceptor(MembershipProvider provider, string realm)
: base(false)
{
this.provider = provider;
this.realm = realm;
}
protected string Realm
{
get { return realm; }
}
protected MembershipProvider Provider
{
get { return provider; }
}
public override void ProcessRequest(ref RequestContext requestContext)
{
HttpRequestMessageProperty request = (HttpRequestMessageProperty)requestContext.RequestMessage.Properties[HttpRequestMessageProperty.Name];
string[] credentials = ExtractCredentials(requestContext.RequestMessage);
if (credentials.Length > 0 && AuthenticateUser(credentials[0], credentials[1], IsTestMode))
{
InitializeSecurityContext(requestContext.RequestMessage, credentials[0]);
}
else
{
Message reply = Message.CreateMessage(MessageVersion.None, null);
HttpResponseMessageProperty responseProperty = new HttpResponseMessageProperty() { StatusCode = HttpStatusCode.Unauthorized };
responseProperty.Headers.Add("WWW-Authenticate",
String.Format("Basic realm=\"{0}\"", Realm));
reply.Properties[HttpResponseMessageProperty.Name] = responseProperty;
requestContext.Reply(reply); // **Here I am getting error**
requestContext = null;
}
}
}
If the username and password in header are valid then whole service runs well. I am getting this error only if request is not authenticated.
Any solution?
Thanks
Resolved it my self :
I had added tag twice in Web.config.
Removed it and now my service is working fine.
I am working with Extjs 4.1 and asp.net
I am trying to fill grid panel from database but getting error. I am using webservice to fetch data.

my webservice code
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json,UseHttpGet = true, XmlSerializeString = false)]
public DataTable displayData() {
db obj = new db();
return obj.getCountry();
}
calling web service from js file
var store = Ext.create('Ext.data.Store', {
pageSize: 20,
model: 'ForumThread',
autoLoad: true,
proxy: {
type: 'ajax',
url: 'report.asmx/displayData',

contentType: "application/json; charset=utf-8",
//url: '/grid.json',
reader: {
root: 'data' ,
type: 'json',
method: "GET",
totalProperty: 'totalCount'
}
}
});
even i remove this line from webservice [ScriptMethod(ResponseFormat = ResponseFormat.Json,UseHttpGet = true, XmlSerializeString = false)] but still same error.
I didnt use XMLSerializer in my code then also it will give me error like There was an error generating the XML document.
You need to supply the datatable with a name, as the error suggests.
dt.TableName = "myTable";
All of the sudden all of the calls to my web services get this error:

I found out the bug myself, all because of a single line Response.Write() in the Session_Start() that mess up everything :(
I built up this regex at http://regextester.com to parse YSOD but VS is complaining about a syntax error. I am sure I am missing an escape somewhere but I am coming up blank.
Here is is in original form. any help is appreciated.
var rxYSOD = /<!--\s*\[(.*?)]:(\s*.*\s(.*\n)*?)\s*(at(.*\n)*)-->/gs;
UPDATE:
Kobi pointed out the obvious and got me moving again. For those who are interested, this is valid JavaScript to test and parse an XMLHttpRequest.responseText for an ASP.net Yellow Screen Of Death (YSOD).
var rxYSOD = /<!--\s*\[(.*?)]:(\s*.*\s(.*[\n\r]*)*?)\s*(at(.*[\n\r]*)*)-->/;
if (rxYSOD.test(text)) {
// looks like one..
var ysod = rxYSOD.exec(text);
errObj = { Message: ysod[2], StackTrace: ysod[4], ExceptionType: ysod[1] };
}
#Kobi - This is the result and the reason I want to parse the html even though I get a 500:

Firefox says:

After removing the s it seems ok (of course, it isn't tested, just parsed correctly).
The flag s is invalid in Javascript. To replace, use the replace method.
