i have built a small mechanism for users to send and receive mail inside my website. this mail system not involving smtp, it's only messages that are saved in the site DB.
right now the only way i can see for checking if a user has new mail is to check the db in every page the user is visiting during his stay in the site which seems to be a bit cumbrous, is there any better approach of doing such thing ?
We at Our company having our own local network in which consists around 20 users. We do not have Internet connections. Now I've created an asp.net website to share the data among the different users.How to create unique mail ids for each user.
View 2 RepliesI am searching for what are the standard best practice (for OOP) used to design classes for develop asp.net application? I am aware of most of the OOP concepts but confused with how to map object/classes.
Let's take example of Adventure works - 2005 database provided by Microsoft; it has five schemas Sales, Purchase, Person, Production, HR and DBO.
Should we consider Schemas as Namespace in Classes?
Now, Person schema has 5 tables, should we design classes based on tables?
i.e. Person schema has Address, AddressType, Contact, ContactType, CountryRegion & StateProvince tables. What are the classes we can consider?
What are the basic criteria to decide objects? What to do and how to design classes for tables like Purchase order detail, Product cost history, Product inventory, Product Category etc.
Page B - loads slowly and needs to do some CPU-intensive operations on the web server.
I noticed that when someone is loading Page B, then Page A also loads slowly. This is even worse if multiple users are loading Page B at the same time. Page A won't finish loading until Page B is done.
Is there a best practice for making sure that Page A can still load quickly? Maybe a config setting or IIS setting that I need to change from its default? With 2 users loading Page B at the same time, the web server CPU usage only gets to 30% so I suspect it might be something I can tweak with the settings.

View 2 RepliesI have a "Contact Us" page where in users will give in their email id and a query and on submitting the form, web admin would receive that email.
If I configure their email id to "from" MailAddress and send the mail, it will fail to do so if the ID is from popular mail domains like gmail or hotmail but would work with other unpopular or non existent domains like me@abcxyzmail.om without any credentials provided!
It worked with gmail after I configured SMTP and network credentials properly. The aim is to let the admin of my website who receives the email be able to hit the reply button in his mail client and see the "to" field populated with the "from" field filled in "contact us" page. Is there any proper way to do this or a tip or trick to accomplish it.

I don't know if it has to be with my application but the thing is that I created a registration form, when the user registers an automatic mail from my mail account at my hosting site is send to the mail account the user input.
The code is working I have tested it with a Hotmail and Yahoo account but Gmail is not receiving.
It is important to say that Hotmail and Yahoo receive the email at the junk mail folder, but Gmail not receives it in any folder. I check my mail account for bouncebacks but there is no problem.
If I change the code to send mails from my gmail account no matter what mail account the user inputs it will receive the mail. I've already contacted my hosting site support but they say they can't find any problem.
I've already waited 48 hours because maybe gmail account would take longer to receive the email but I haven't received it.
Here is my send email code:
