Web Forms :: Creating Messages As A Thread?
Jan 20, 2010
Im creating a messaging system which is a bit like the inbox feature of this forum. So far I have built the page with a datalist (as this is the advice i was given). I just want to know how I should create the tables within the database so that the thread of messages is seen by the right people when they login and view messages. Which is basically the 2 people messaging each other. The system is gonna have user sign in functionality as well.

Im creating a messaging system abit like the inbox feature of facebook and even this website (its gonna be created as a asp.net website). Now the messages ive been told should go to a database and then from there be displayed on a page. Im gonna be creating this system because its a project for university. Its not going to be published online or anything, just a simple demo in front of suoervisor n examiner. Im gonna simply create a database within the application to hold all the data.Now i need to have user login feature capability so the right messages are displayed to the right users. I wants the messages to be as a "thread". Any idea how this can be done in asp.net? im using visual studio 2008 .net framework 3.5.

I have a very long running process that I start in a thread. This raises events with messages to say what it is doing.
How can I update a label on screen with these messages? (The label is in an update panel if that makes it easier).

I am using jQuery to call PageMethods. For certain operations, the current user credentials must be validated and for other operations, I need to call other static methods. Here is some sample code:
Sample #1
[WebMethod]
public static void PostComment(string comment)
{
UserAuth auth = new UserAuth();
if (auth.isAuthenticated)
{
//Post comment here...
}
}
Sample #2
[WebMethod]
public static string GetComment(int commentId)
{
commentDto comment = //get comment data from the database...
string friendlyDate = ConvertFriendlyDate(comment.commentDate);
return friendlyDate + " " + comment.text;
}
public static string ConvertFriendlyDate(DateTime commentDate)
{
string friendlyDate = //call static utility method to convert date to friendly format
return friendlyDate;
}
Will I be safe using these kinds of operations? Am I better to drop page methods and just call a separate ASPX page for my AJAX requests?

For error messages, validation faults etc you have
ModelState.AddErrorMessage("Fool!");
But, where do you put success responses like "You successfully transfered alot of money to your ex." + "Your balance is now zero". I still want to set it at the controller level and preferably in key-value way, the same way as errormessages but without invalidating the modelstate.

I'm new to threading and have used it successfully, but limited. I can spawn a thread and have the main thread reference variables in the spawned thread, but I don't know how to allow the spawned thread to reference (and update) variables in the main thread.
Any example threading code I've seen on the web appears to be WAY more complicated than what I do, so I am unable to understand or integrate into my code.
Here is a quick example of how I use threading:

I am reading the Asp.net security documentation on msdn.I come across these tow terms and get really confused.
# WindowsIdentity = WindowsIdentity.GetCurrent()
which returns the identity of the security context of the currently executing Win32 thread.
# Thread = Thread.CurrentPrincipal
which returns the principal of the currently executing .NET thread which rides on top of the Win32 thread.

I have a password page and when someone enters an incorrect password I want to simply foil a brute force attack by having
bool isGoodPassword = (password == expected_password);
lock (this)
{
if (!isGoodPassword)
Thread.Sleep(2000);
}
I would expect that this would allow all correct passwords without stalling, but if one user enters a bad password another successful password from a different user would also be blocked. However, the lock doesn't seem to lock across ASP.NET threads.

When my validation fires on my web form, the validation summary writes out the same error message for each control that was in error
twice! I have no validation groups in my web form.Here is my html for the Validationsummary control.
<code>
<asp:ValidationSummary ID="ValidationSummary1" runat="server" DisplayMode="BulletList"
ShowMessageBox="true" ShowSummary="false" EnableClientScript="true" HeaderText="You must enter a value in the following fields:" />
</code>
A typical control is set up below as follows:
<code>
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" ControlToValidate="HospAcctno"
ErrorMessage="Patient Info: Hosp Acct#" Text="*" runat="server" />
</code>

I have a form that has contact fields, billing address, and shipping address. So if i fill out my contact information ONLY and left billing and shipping address blank then hit submit, the validation for the billing address and shipping address appears. Ok no problem, there is a check in each billing and shipping fields that once click on it copies the address from contact to billing or shipping fields. Everything works except for the validation messages. They are still there. Is there a way to remove the validation message after the textboxes are populated with data?

I'm having a registration form with textboxes that have more than one validator, e.g. a requiredfieldvalidator and a comparevalidator. I want the error message to show up on the right side of the textbox, but because I use more than one error message, one of them is not neatly next to the textbox, but further away from it.
