Thanks - Google doesn't like me, I've decided  I did try and Google this myself....

I've written that before years ago, it was just easier for me to find it through search and post a link. Took me a while to find the right one.

You'll need to debug it and see what is happening.

Hi,
I have a pretty long and complex logic that needs to be run when the page loads.
The logic can't be changed.
What happens is that while the logic is executed, the page is of course stuck.
It involves drawing on the canvas element.
What options do I to work around this issue?
|
|
|
|
|
|
Thanks, I'll go over this info.
|
|
|
|
|
Thanks for your feedback.
I went through those links.
It looks something that could handle my problem but I need to draw a very complicated structure on the canvas + perform some interactions on it later and to do that, I need an access to the DOM + window which I don't
have through the web worker.
Any ideas how can I get around this?

I am writing to seek help, in regards to figuring out, how can I verify my email address using mx record. I am currently new into using MX records and so far, I have method which returns a mx record for specific domain (as shown below):
public static string mailMX()
{
string domainName = "#######.com";
string mail = "";
var response = DnsClient.Default.Resolve(domainName , RecordType.Mx);
var records = response.AnswerRecords.OfType<MxRecord>();
foreach (var record in records)
{
return (record.ExchangeDomainName).ToString();
}
return mail = records.ToString();
}
My desire goal is to create a method, which can verify the email address "info@reply.####.com" has a valid mx record and return the email address. I am slightly struggling in this area, as I am not to sure how to structure this task.
Any hints would be most appreciated. Thank you

Ignore the ExchangeDomainName - that's just the name of the server which accepts email for the specified domain.
If there are any MX records for the domain, then the domain is valid. It won't tell you whether the mailbox actually exists, but you can't determine that without trying to send an email.
Try something like this:
public static bool IsValidEmailDomain(MailAddress address)
{
if (address == null) return false;
var response = DnsClient.Default.Resolve(address.Host, RecordType.Mx);
if (response == null || response.AnswerRecords == null) return false;
return response.AnswerRecords.OfType<MxRecord>().Any();
}
public static bool IsValidEmailDomain(string address)
{
if (string.IsNullOrWhiteSpace(address)) return false;
MailAddress theAddress;
try
{
theAddress = new MailAddress(address);
}
catch (FormatException)
{
return false;
}
return IsValidEmailDomain(theAddress);
}

Thank you very much for your reply. Apology for the late response.
When I tested the IsValidEmailDomain method, for my domain, it showed up as false. I tried adding in the try...catch block, but I am still getting a false domain address (####.com) and I have also tried testing it using my personal domain address (####@gmail.com), which also results in false.
I have tried compiling many variations of the test method, to catch the error within the IsValidEmailDomain, but I keep experiencing false/null for each of the domain address.
public static bool IsValidEmailDomain(MailAddress address)
{
if (address == null) return false;
var response = DnsClient.Default.Resolve(address.Host, RecordType.Mx);
try
{
if (response == null || response.AnswerRecords == null) return false;
}
catch (FormatException)
{
return false;
}
return response.AnswerRecords.OfType<MxRecord>().Any();
}
public static string test()
{
string mail = "#####6@gmail.com";
bool? answer = null;
Exception ex;
try
{
answer = IsValidEmailDomain(mail);
}
catch (Exception e)
{
ex = e;
}
if (answer.HasValue)
{
return answer.ToString();
}
else
{
return null;
}
}
However, when I test the following domain address (###.com) with my original mx() method, it displays a mx-record (mail.###.com) for my domain address. I have also tested my mx() method using my gmail address and it outputs an mx-record for it.
public static string mailMX()
{
string domainName = "#######.com";
string mail = "";
var response = DnsClient.Default.Resolve(domainName, RecordType.Mx);
var records = response.AnswerRecords.OfType<MxRecord>();
foreach (var record in records)
{
return (record.ExchangeDomainName).ToString();
}
return mail = records.ToString();
}
I am trying to send email via XML to 3rd party client via web request and in order to send the email, i need to pass a email (reply.###.com) with a valid mx-record. hence, how can I build method, which define, that domain address (###.com) is valid with the following (mail.###.com) mx record.
Any hints to where I may be going wrong or what logic I should be applying, would be most helpful.
Many thanks for your time and help.

I'm assuming the DnsClient class comes from the ArSoft.Tools.Net[^] project?
Based on their documentation, I've made one slight adjustment to the methods I previously posted:
public static bool IsValidEmailDomain(MailAddress address)
{
if (address == null) return false;
var response = DnsClient.Default.Resolve(address.Host, RecordType.Mx);
if (response == null) return false;
if (response.ReturnCode != ReturnCode.NoError && response.ReturnCode != ReturnCode.NxDomain) return false;
if (response.AnswerRecords == null) return false;
return response.AnswerRecords.OfType<MxRecord>().Any();
}
public static bool IsValidEmailDomain(string address)
{
if (string.IsNullOrWhiteSpace(address)) return false;
MailAddress theAddress;
try
{
theAddress = new MailAddress(address);
}
catch (FormatException)
{
return false;
}
return IsValidEmailDomain(theAddress);
}
Testing those methods using v1.8.1 of the library produces the expected results:
IsValidEmailDomain("test@gmail.com") == true;
IsValidEmailDomain("test@test.test") == false;
If those methods don't product true for a gmail.com address, then you need to check your DNS servers. Open a command prompt and type the following:
nslookup
set type=mx
gmail.com
You should see a list of the MX records for the domain.

In a vb.net 2010 web form application. I need to allow the help desk to be able to query up to 3 different tables when the need arises. This a support web page that supports a particular application that already exists.
The web page gives the help desk people directions for updating active directories and searching 2 tables.
My questions are about the 2 tables that need to be searched which includes:
1. If I place the access to all 2 tables on the same webpage in 2 separate gridview controls. is there a way for the webpage to show up all 2 gridview controls containing no data The user would have to complete searches to obtain the data. If so. can you show me code. point to a reference and/or tell me how to accomplish this goal?
2. Would you place the gridview controls on the same web page or different web page? Would you tell me where you would place the 2 gridview controls and why you decided on your recommendation?

Hello
I have a couple of aspx forms in my VB.NET project. Eventually, these forms will be used on a Classic ASP site which has already been created. The user will click on a link on a Classic ASP page and one of these ASP.NET forms will appear in a smaller window as there is no need for a log-in form to occupy the entire screen.
Therefore, I need to reduce the size of the form that I have - at the moment each form fills the whole screen - and I wonder what is the best way of reducing the size of the form?
Thanks!

You would have to size everything using % in CSS
width: 100% or width: 80%
Its no different than making the same page expand and contract resizing the browser window

Thanks for that jkirkerx,
I didn't realise it has to involve CSS.
Sorry for the late reply.

I was reading some articles about how to implement a service layer in MVC applications yesterday. One thought that came to mind was: what about data annotations used for model state validation? When you implement a service layer, do you get rid of those data annotations (like [Required] or [MaxLength]) for the model classes? This[^] is the article I was reading.
MVC development is mostly new to me, aside from the fact that I have a fundamental knowledge of the core concepts. I switched employers recently and our work here is done primarily in MVC, which I'm happy about because I've been wanting to get into it for a while now. My two coworkers are more knowledgeable than I am, for sure, but they're open to new ideas and new techniques that may help improve the applications. I figured a service layer would be beneficial not only to remove business/validation logic from controllers, but also because we're starting to write unit tests.
