Is this only a declaration of intent, or do you have a question?
Have you tried anything towards building this? Anything at all? Like database model? Made a login form? Written any code?
Who is this "u" person you are talking about all the time? If you write proper english you will be taken more seriously.

Hi everyone,
I want to release the memory back to the server immediately or explicitly free up memory, should I set DataSets/DataViews to null after use or should I use .Dispose() method? Or both?
Thanks. I appreciate any help.

Hi there,
It's a good practice to release the resources back to the system, however if you want it immediately, then i'm afraid you cannot. To some extend, you may use the Collect method of the GC[^] class to force the garbage collection. You can read more about this in the documentation Garbage Collection [^]

Hi Guys!
need Some Help...
i m developing an Asp.net application in c# which download mails from POP3..
the application is working good but when we close the browser..
the w3wp (IIS Worker Process) does not end and due to which if we refresh the page 4-5 times an out of memory exception is thrown. but if we end that process manually it works fine...
i found outsome where to set the IIS Applicationpool Health monitoring idle Time property to set to 2 or 3 min.. to end that process.. but it affects all the application running in IIS
i only want to end that process for my application ...
can we do it through code.. or some other procedure..
can any one help me out for what to do..

Is it possible you are leaving something or some object open and that is what is causing your problem? I would suggest finding out why it is staying open not just trying to close it manually.

Since you mentioned an UpdatePanel I'll assume you're refering to Atlas in ASP.NET 2.0. If that is the case I would first suggest contacting infragistics (whose support is ok) and see if they have got this same type of thing working.
While you wait for their reply you could always make a simple test page with just the webdatechooser and an update panel to see if you can get the page to work with just those controls.

Hi All,
This is a bit of a complex one, appologies in advance if this post ends up being long.
I am creating a dynamic questionnaire system, which is data driven, is split across pages and has 4 different types of question (SingleSelect, MultiSelect, SingleLineTex, MultiLinetext) each created as a UserControl. Each page of the questionnaire can have multiple groups of questions (called a QuestionGroup), and each question group can have multiple Questions.
The problem im facing, in brief, is that when the page is posted back the data for the questions within a group is no longer available. Im tearing my hair out with this, as winforms dev is my normal thing and not knowing how to do something in web development is mighty frustrating!!
Ill try to be more detailed. I have a web user control called QuestionGroupControl , roughly defined as follows:
<%@ Control Language="c#" AutoEventWireup="false" Codebehind="QuestionGroupControl.ascx.cs"
Inherits="BroadSystem.QuestionnaireWeb.Controls.QuestionGroupControl"
TargetSchema="http://schemas.microsoft.com/intellisense/ie5"%>
<asp:Table Runat="server" ID="QuestionGroupTable" CssClass="questionGroup" CellPadding="0"
CellSpacing="0">
<asp:TableRow>
<asp:TableHeaderCell CssClass="questionGroupHeader">
<%# QuestionGroup.Text %>
</asp:TableHeaderCell>
</asp:TableRow>
<asp:TableRow HorizontalAlign="Left">
<asp:TableCell CssClass="questionGroupBody">
<asp:Panel id="QuestionGroupPanel" runat="server"></asp:Panel>
</asp:TableCell>
</asp:TableRow>
</asp:Table>
QuestionGroupPanel is where I dynamically populate each question within that group (this can be one of 4 controls as defined above). Here is the code im using in the code behind of the QuestionGroupControl :
protected override void OnLoad(EventArgs e)
{
foreach(QuestionnaireDataset.QuestionRow question in this.QuestionGroup.GetQuestionRows())
{
string control = question.QuestionTypeControl;
QuestionnaireBaseUserControl ctrl = (QuestionnaireBaseUserControl)LoadControl(control);
ctrl.Question = question;
this.QuestionGroupPanel.Controls.Add(ctrl);
}
base.OnLoad (e);
}
And for clarity this.QuestionGroup is defined as follows:
public QuestionnaireDataset.QuestionGroupRow QuestionGroup
{
get
{
return questionGroup;
}
set
{
questionGroup = value;
}
}
You can see im using a typed dataset, and within my aspx page this is the relevant section.
<asp:Repeater id=Content Runat="server">
<ItemTemplate>
<BS:QuestionGroup ID="QuestionGroup" runat="Server" QuestionGroup='<%#Container.DataItem%>' />
</ItemTemplate>
</asp:Repeater
I, of course, assign my QuestionGroup datatable as the datasource for the repeater on the page.
The error I get is within the OnLoad override in the QuestionGroupControl - it says (quite rightly) that on this line:
foreach(QuestionnaireDataset.QuestionRow question in this.QuestionGroup.GetQuestionRows())
that this.QuestionGroup is null.
Im 99% sure its the order in which im building the controls up, has anyone got ANY pointers for me?

Um, this might be a bit simplistic and i'm not understanding, but how are you persisting your questionGroup variable across postbacks. Unlike winforms, the questionGroup variable that you wrap with the public property will not automatically be persisted.
Also, and this is just nit-pickery, but public properties on aspx pages is not particularly good practice - particularly with the new 2005 project structure.
(BTW, seeing the current blacklist makes me really want to try and get on it... It's like an itch that i really shouldn't scratch...

Thanks for the reply... I should have added that this is .NET 1.1 not 2.0
I am not persisting the questionGroup variable, and I think this is at least part of the issue. I tried storing it in ViewState originally but I get an error saying that an object of that type needs to be marked as serializable or have a type converter defined...as the code (for a typed dataset) is autogen'd I cant add either of these!
As for the nit-picky-ness that property was supposed to be protected, and is there for syntactic sugar - its not part of any real functionality.
As for the blacklist, feel free to be rude, abusive or insulting and you'll be added in a second The downside is that I answer about 100x more questions here than I ask. (in fact this is the first time I ever remember asking a question and I have about 800 posts!) A position on the list ensures I never answer your questions!

That's going to cause you problems - you'll need to either store the dataset somewhere or rebuild it on every postback. I've never worked much with typed datasets, so i don't know about marking it serializable, but it's kinda funny, as an ordinary DS is serializable by default...
And i think i'll just stay itchy in that case...

Hi there,
Do you get the error on postback? If this is the case, IMO there are two options that you may consider:
+ Persist the length of the QuestionGroupRow object instead of the object itself in the ViewState so that when the page posts back you can re-create the control hierarchy in the user control.
+ Disable the ViewState of the repeater control, and bind the datasource to the repeater every time the page is visited.

Hello,
Is there any way to get specific records from XML file using ASP.Net with VB.Net?
There are two XML files one for categories and other for products. I want to get products against specific category.
Or can we use "Select Query" in XML files?
If you know the solution then please let me know.
Bye,

How are the two files linked?
Xml forum might be a better place to ask...

Does anyone have any info on whether it is possible to modify postback info client side? I have added some javascript functions for ordering a select (listbox) control but cannot sucessfully change the postback to reflect these changes.
Is Ajax the only way to go? I'd rather not have to create pages to process the data if possible, I just want to persist the changes!

Maybe I'm just slow this morning but I'm not sure what you mean. Do you need to select a new item in the listbox and have it update a datagrid(or other control) immediately? If so you can either use Ajax (I'm not sure how to implement yet) or you can make the listbox a server side web control and tell it to postback (using AutoPostBack) on item changed.

I think what's being asked for is a way to postback to the server changes made to the order of items in a listbox via client-sode Javascript.
One way is to include an asp:Textbox with Viasible=False (this renders on the page as input type="hidden") - you can then use your JS functions to update the value of this with the values of your listitems when re-ordered (seperated by commas, maybe) and this will then be sent to the server on a PostBack, where you can read in and parse the textbox.text to get the new order.
Hope that helps
Phil

Actually, of course, it doesn't have to be an asp;Textbox Visible=false - it can be an ordinary input type="hidden" field, and it's value can be read on PostBack by a simple Request call...
