I need to dispose of some resources at the end of each request...am I safe to just use Application_EndRequest or if something crashes will that not be hit (should I have the dispose code in Application_Error as well?)
View 2 RepliesI am building a simple performance logger that hooks in to Application_EndRequest / Application_BeginRequest
I would like to send my logger the name of the action and controller as some sort of key.
How can I access this information? (Don't mind if I have to intercept it earlier on and keep it around in the context)
Is there a way to retrieving parameter names and values passed to a web method from Request object? I've read somewhere that you need extra code to access the soap body. Any known workarounds to be able to see the soap body from Application_BeginRequest?

I want to sign out a user when his session times out. So used following code in Global.asax:
protected void Session_End(object sender, EventArgs e)
{
FormsAuthentication.SignOut();
}
But seems session_end never fires. Any idea how can fix it? I'm using ASP.NET with default settings.

Can I fire a custom event in asp.net according to my needs ?
I am making a simple chat application for my website.
I am using cache variable to store my chat. When I submit my textbox cache variable updates and text is cache variable is displayed to both the users. Since , I get a postback , my page refreshes and I get an updated value of cache variable but the other user needs to refresh the page.
So, is there any method, which can check if cache variable has been updated and fire an event , so that , I can deliberately force the browser to refresh.
One more problem , I am want to list the online users of my website. ( I need to list all sessions currently active ).
I think , best possible way is to insert current date, time on database after every 10 seconds by all users. How can I get an event which can update a column of database every 10 seconds ?

I have to establish an HttpListener that will wait for requests made by our client's server. I have to receive that request on port 8088 and extract the query string. That is the easy part.

View 1 RepliesI have a form with several text boxes on it. I only want to accept floats, but it is likely that users will enter a dollar sign. I'm using the following code to remove dollar signs and validate the content:
jQuery:
$("#<%= tb.ClientID %>").change(function() {
var ctrl = $("#<%= tb.ClientID %>");
ctrl.val(ctrl.val().replace('$',''))
});
asp.net validation:
<asp:CompareValidator ID="CompareValidator4" runat="server" Type="Double" ControlToValidate="tb" Operator="DataTypeCheck" ValidationGroup="vld_Page" ErrorMessage="Some error" />
My problem is that when someone enters a dollar sign in the TextBox "tb" and changes focus the validation happens first and THEN the jQuery removes the dollar sign. Is it possible to have the jQuery run first or to force the validation to run again after the jQuery executes?

I have an image on my page than can be changed from a fileupload asp.net control on the page, i want to provide and alternative to clicking the button by allowing the user to click their image. i gave the fileupload a class 'jqueryPhotoUploadTrigger' and it renders like this:
<input type="file" name="ctl00$ctl00$ctl00$ContentPlaceHolderDefault$C2kMasterPlaceholder$ucEditDetails_20$photoupload" id="ctl00_ctl00_ctl00_ContentPlaceHolderDefault_C2kMasterPlaceholder_ucEditDetails_20_photoupload" class="jqueryPhotoUploadTrigger" />
i then have jquery script at the bottom:
$(document).ready(function() {
$("#clickMyColl").click(function () {
alert("image has been clicked");
$('.jqueryPhotoUploadTrigger').click();
});
});
the alert does show so i know the script is firing when i click the image. i was just hoping the .click would fire the event on the button but it didnt. can i do it this way or must i find an alternative?

I noticed on a number of formviews that my validation controls seemed to be firing twice (which they were). I just found a case where a "Save" button had
onclick="UpdateButton_Click" in its defintion on the aspx page as well as the event routine having a "Handles UpdateButton.Click." This scenario made the UpdateButton_Click code run twice (and thus I expect that any validation controls would fire twice as well). When I removed the onclick="UpdateButton_Click"from the button defintion, the code only ran once, as desired. This double validation has gotten me especially with customvalidators.
Protected Sub UpdateButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles UpdateButton.Click
<my code>
End Sub
The question now is, why does having the onclick defined as well as the "Handles" on the event routine cause a double run of the event routine?I am going back into all my code to find where I have this "double" hit and remove the onclick in those instances.
I have a eventhandler in code behind of a UserControl.
