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 am sending you the code. It Has two PArts First is CLIENT SECTION and Anpother is STATION Section
1) CLIENT SECTION : It has a dropdownlist binded to SQLDataSource and with this it has an imagebutton bAddClient
bAddClient will open the ModalPopup which will ask user to Add new client. And After Adding the New client when User
will close the ModalPopup MY DropDownList is not getting Populated with the New Client. I have Used UpdatePanels Also
2) STATION SECTION : It has a DropDownList, an Image BUtton , And Grid View. In Grid View it shows station details
On particular client selcted above.
I have given the delete station command on deleting the station that particular entry doesnot goes away.
It Should not be visible after it get deleted
Now when i click on imagebutton a modalpopup will open.
Now In modalpopup i have given dropdownlist , image button(to add new station), Some station Info and save button
Now when i click on dropdownlist it used to close the modalpopup then i seet the autopostback = false. Then it works fine. Is it correct way?
Now when i click on imagebutton it asks user to add new station with a textbox , save station button. When users click on savestation button then it adds station to the DB and it should update the dropDownList of ModalPoup without closing it.
But when I am clicking on imagebutton it is closing the modalpoup.
And When user clicks on ModalPoup SSave Button in end it should update GridView of STATAION SECTION too.
<%-- ************** CLIENT SECTION START HERE*******************--%>
<p class="heading">CLIENTS</p>
<br />
<asp:ScriptManager ID="smClientMgmt" runat="server" />
<asp:UpdatePanel ID="upCMClientInfo" ChildrenAsTriggers = "true" UpdateMode="Conditional" runat ="server" >
<ContentTemplate>

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?

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.

A breakpoint is set on FillForm() and this method is called two times but I can't explain myself why this happens. I have client side javascript code, when the form is being send, the onsubmit method is also called twice... Where do I have to search?! Is it a (known) bug? Think I could get it to work with this Thread: [URL] But why is the event fired within the onblur-event when it's fired anyway??

I want to pass a property of the type System.Uri to an WebControl from inside an aspx page.
Is it possible to pass the property like that:
<MyUserControl id="myusercontrol" runat="server">
<MyUrlProperty>
<System.Uri>http://myurl.com/</System.Uri>
</MyUrlProperty>
</MyUserControl>
instead of:
<MyUserControl id="myusercontrol" runat="server" MyUrlProperty="http://myurl.com/" />
which can't be casted from System.String to System.Uri EDIT The control is a sealed class and I don't want to modify it or write an own control. The goal is to set the url-property which is of the type System.Uri and not System.String.

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.
