I have a .exe application that runs daily. I want to avoid sending emails each time an exception is caught.I want to compile a list of errors (in a unique log file fileupload[mm/dd/yyyy].log) while the application runs. Then send an email with the log attached after it the application finishes.What would be the approach for this?

I have the code above, if after half of the emails were sent out, there is a error in smtp, then how can I avoid resending emails or missing emails in this cases ?
Using VB, VS 2010, I am wanting a remote web app to send me an e-mail when it finds an error using the try catch. What is the best way to do that?
View 4 RepliesMy question is, I have a PL, BL and DAL layered architecture (In which all these components are hosted in a single web server).
With the above architecture, i have only placed try catch block in all my events in aspx.cs pages in PL ALONE and NO TRY CATCH BLOCK IN BL AND DAL.
There is one command timeout exception happening at the DAL layer and the exception bubbles back to the PL(aspx page event which is having the try catch block). This try catch block catches the exeption and logs the exception information to database and displays useful information in the UI.
WIth the above approach, sometime very rarely(only once till now) exception is not caught in the PL for the commandtimeout exception thrown from DAL implicitly.I confirmed the exception is not caught because the exception information is not logged into the database and also no useful information displayed in UI.
Why the exception from DAL dint bubble down to PL? Do we need to explicitly throw exception from DAL or BL i.e by having try catch block in BL and DAL ?
I have tried this on two different controller methods now, and both times, even if the linq2sql doesn't allow the data to be saved, the code never jumps into the catch block.
I've watched the noun object in the middle of the trace, and the isvalid property is false, but the modelstate isvalid is true. Either way, the code never jumps into the catch block.I'm pulling my hair out about this. I feel like it will be something really silly.
The code all works similar to nerd dinner.
NounRepository nounRepository = new NounRepository();
Noun noun = new Noun();

I'd rather not have to add code in this manner though, as it seems like an unnecessary duplication.
I have (pretty much) the following code in my protected void Application_Error(object sender, EventArgs e) method in Global.asax....
Exception ex = Server.GetLastError();
if (ex is
System.Security.SecurityException)
Response.Redirect("Logon.aspx");
else
Response.Redirect("ErrorPage.aspx");
If I navigate to a page before I log on the exception is caught and I am redirected to Login.aspx as I would expect. However, this is only working when debugging using VS on my local machine.When uploaded to the live environment, the exception is not caught and the user is presented with "Security Exception - Request for principal permission failed."
I have a page here with a few list views on it that are all bound to Linq data sources and they seem to be working just fine.I want to add validation such that when a checkbox (IsVoid on the object) is checked, comments must be entered (VoidedComments on the object).
Here's the bound object's OnValidate method:
partial void OnValidate(ChangeAction action)
{
if (action == ChangeAction.Update) [code]....
Despite there being a dynamic validator on the page referencing the same ValidationGroup as the dynamic control, when the exception fires, it's caught in JavaScript and the debugger wants to break in. The message is never delivered to the UI as expected.
When the Stored procedure is executed through SQL Server Management Studio, its taking 23 seconds,When the same Stored proc is called through web app, its throwing below copied exception. It is noticed that when the data is more than 100k records this exception is thrown other wise expected records are shown in UI. Another stored proc from the same app returns over 150k records without any excetpion. Can't conclude that the exception is in Stored proc, because it works from SQL Server Management studio, but throws below exception from Web app.

I have a requirement like sending multiple mails for each update in database.But if i write mail sending code on button click then it will delay the page load time till all mails are send.Is there any way to send mails using seperate thread that runs at backend or maintain a queue.
One more think content of all mails are not same always.
public void mail()
{
System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage();
System.Net.Mail.SmtpClient smtpClient = new SmtpClient();
//create the mail message
//set the addresses
mail.From = new MailAddress("kamalakkanavar@gmail.com");
mail.To.Add(TextBox1.Text);

View 13 RepliesI'm sending automatically emails when customers buy products on my ecommerce portal.
But, send pages by emails, at least in my server, using asp.net is too slow.
So, I want to send emails automattically, but using SERVER PROCESSING (Server Side). Did you get my point?
The customer won't see the sending process. But in background, directly on the server, the email is being sending.
write code that can send bulk emails from an access database using asp.net/vb? I only need to send about 200 emails per day. also the email must be addressed to that person, eg. if the email address is kylesmith@gmail.com then the email should read Dear Kyle as well as the TO field should state kylesmith@gmail.com

For the first time in my career, I'm working on an ASP.Net (v3.5) project that has been set up as a Visual Studio 2008/10 Web Site Project.
I'm not keen on this way of working this way for various reasons but for the moment and until such time as the company sees the virtue in working in an environment with namespaces, designer and project files etc., I have to continue with the existing codebase.
I've run into some odd issues since I began this but perhaps the oddest one of all is that althought VS lets me build the code, it doesn't reliably pick up compilation errors so these are not noticed until runtime.
I know the website model allows dynamic/hot compilation when a request is made for a specific but I can't see why it wouldn't do this when I manually (F5) build/rebuild the project. Its immensely annoying as you can imagine and I can't find a workaround.
In our project WCF service is acting as our BLL.
i had scenario where i had to fill list of object class without knowing its type see code:

My code sends email via asp.net mail namespace. Basically I generate HTML code which carries an image tag referring to an image on server. It uses absolute path and then the html email is sent to recipients.
Now when they receive emails on gmail and other clients, it wouldnt display images and not that images are broken but it wouldnt get displayed. Gmail is an issue wherein it prompts of non-https message and then display link on top. I know how to get around but my recipients have no clue on this technical things. so they end up not seeing the images.
How can I resolve this issue? How can I ensure that they always receive images irrespective of their internet settings?
Here is my situation and hopefully someone could guide me in the right direction.I have a shared or static class in my website (App_Code folder) which has static methods to send emails asychronoulsy. So whenever there is an exception in any of my pages or classes I call these methods to send an email to support asynchronously. Now when there is an exception in a page, to route that exception asynchronously I need to have Async = "true" for that page. I have more than 50 pages and I don't want to set Async= "true" on every page as I read that it affects performance.So I was wondering if there is any way I could send emails asynchronously without having to set async = "true" on every page.
View 7 RepliesI'm having an issue sending large volumes of emails out from an ASP.Net application. I won't post the code, but instead explain what's going on. The code should send emails to 4000 recipients but seems to stall at 385/387.
The code creates the content for the email in a string.
It then selects a list of email address to send to.
Looping through the data via a datareader it picks out the email address and sends an email.
The email sending is done by a separate method which can handle failures and returns it's outcome.
As each record is sent I produce an XML node in an XML document to log each specific attempt to send.
The loop seems to end prematurely and the XML document is saved to disk.
Now I know the code works. I have run it locally using the same SMTP machine and it worked fine with 500 records. Granted there was less content, but I can't see how that would make any difference.
I don't think the page itself times out, but even if it did, I was sure .Net would continue processing the page, even if the user saw a page time out error.
Is there any samples on how to use ASP.NET built-in templates out of the page, just for rendering text with params. For instance, to build email message.
View 2 RepliesI am using the ASP.NET membership provider controls (ChangePassword and PasswordRecovery) and they generally work just fine. Unfortunately they don't send any emails once the process is finished. I set up the SMTP server using the ASP.NET Configuration Website and it added the following lines to the web.config:
<system.net>
<mailSettings>
<smtp from="maildaemon@pagetailors.de">
<network host="pagetailors.de" password="XXXX" userName="XXXX" />
</smtp>
</mailSettings>
</system.net>
I also tried using the IP adress of the server instead of the domain. In addition to that I set the maildefinition properties on the used web controls:
<MailDefinition From="maildaemon@pagetailors.de"
Subject="Your new password">
</MailDefinition>
Once I finish changing or resetting the password, the controls shows the success message. It does not show any errors but the mails are not sent. I also checked the SMTP log files on the server (it's a MailEnable server) but couldn't even find an attempt to send these messages. I am using a custom email helper class which manually sends an email using the following settings:
public static void SendEmail(string from, string to, string subject, string body)
{
SmtpClient mailClient = new SmtpClient(ConfigReader.GetStringValue("MailServer"));
mailClient.Credentials = new NetworkCredential(ConfigReader.GetStringValue("MailUsername"),
ConfigReader.GetStringValue("MailPassword"));
MailMessage mailMessage = new MailMessage(from, to, subject, body);
mailClient.Send(mailMessage);
}
The values for mailserver, username and password read from the config file are the same as defined in the ASP.NET configuration tool. These mails are delivered successfully.
I am writing an application that will need to send a massive amount of emails to our students who will be selected from our database (each email will be personalized to the extent that will include their name, course of study etc...so needs to be sent one at a time).
I could do this looping over an SmtpClient, but I'm afraid that with the numbers I'm trying to send, I'll ultimately run into timeout issues or my thread being killed because of lack of machine resources. if looping over SmtpClient is an ok solution, how I should go about handling it to prevent what I posted above.
