C# - Comparing Two Times That Are Shown On Form As Dropdowns For Hours And Minutes
Feb 8, 2011
I have been working on a .NET/C# form that contains two time fields that are built out of dropdowns. Time A is made up of two dropdowns for Hours and Minutes and Time B is made up of two drop downs for hours and minutes too. I need to compare the two in order to ensure that Time A is always greater than B. I could just use a CompareValidator to check the hours, that works BUT doesn't take into account the minutes. So lets assume the following scenarios:
A = 11:00 B = 12:15 is fine my validation accepts this as it should do
A = 11:15 B = 11:00 is accepted because the hours are equal but otherwise shouldn't pass as the minutes aren't validated
How would you ensure B is always equal to or greater than A where dropdowns are used? I would if I could change this but not permitted to do so.

I'm trying to calculate the yrs, months, days, hours, mins, seconds between two dates with sql server or c# (ive just used sql more).
I have some code below that I started, but I get some negative values for months, values over 31 for months, and there very well could be more issues. Honestly my math is not the greatest and Im just not sure how to fix it. I want the user to be able to enter their birthday and for it to calculate the yrs, months, days, hours, mins, and seconds they have been alive.

I would like to get the accurarte (days, minutes, months and years) differnce between two date time variables and not just who is greater.
Is there a better way to do it then run DateTime's methods (TotalDays, TotalHours, TotalMinutes. etc...) and do the calculation?
The bottom line is to display something like "a minute ago", "an hour ago", "Three weeks ago", etc...

We have an ASP.Net web service the call to which, due to some bad design, often takes more than 20 minutes to return. We have changed every setting that we can think of, but no matter what we do, we always get a timeout after 20 minutes. It happens that this web service is a BizTalk orchestration exposed as a web service, but I do not think that is relevant -- the error is an ASP.Net error.
There must be some setting we can change to increase the timeout to more than 20 minutes, but we've exhausted our knowledge. What setting are we missing? EDIT: Among other setting, we have tried those detailed here: [URL], which includes httpRuntime executionTimeout, sessionState timeout and app pool idle timeout.

I have a very peculiar problem that I've been wrapping my head around and I just can't figure it out. I have an updatepanel. Inside that I have a TabContainer. And inside that I have three TabPanels, each of which has checkboxes. Sometimes (and it happens often enough that I can easily reproduce it, but strangely may not happen with the same exact steps), when I click on different tabs or click on checkboxes inside the tabpanels (basically when I do an AJAX async postback), the request takes about a few minutes, after which the request just stops. Looking at the Firefox error console, I see this popping up after a few minutes...
Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 0 Now, the asyncpostbacktimeout property for the ToolkitScriptManager is set at 360000, which is 6000 minutes, so the problem has nothing to do with that setting. In IE, I never have this problem and the AJAX requests are instantaneous and smooth, no delays. So this isn't a network or database lag issue. Something to do with how AJAX is run in Firefox. Why is it that sometimes, an AJAX request in Firefox takes a few minutes and just stops processing the request? And once again, the steps to reproduce this problem may not be the same every time, it seems random - very strange. Google searches have yielded very little help on this. I've tried things like extending the timeout property (which again has nothing to do with this), setting Response.Cache.SetNoStore() everywhere. Is there a crude workaround I can do (at this point, I'm willing to settle for a workaround). I just don't know anymore.

I have a site that is using Forms Auth. The client does not want the site session to expire at all for users. In the login page codebehind, the following code is used:
// user passed validation
FormsAuthentication.Initialize();
// grab the user's roles out of the database
String strRole = AssignRoles(UserName.Text);
// creates forms auth ticket with expiration date of 100 years from now and make it persistent
FormsAuthenticationTicket fat = new FormsAuthenticationTicket(1,
UserName.Text, DateTime.Now,
DateTime.Now.AddYears(100), true, strRole,
FormsAuthentication.FormsCookiePath);
// create a cookie and throw the ticket in there, set expiration date to 100 years from now
HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName,
FormsAuthentication.Encrypt(fat)) { Expires = DateTime.Now.AddYears(100) };
// add the cookie to the response queue
Response.Cookies.Add(cookie);
Response.Redirect(FormsAuthentication.GetRedirectUrl(UserName.Text, false));
The web.config file auth section looks like this:
<authentication mode="Forms">
<forms name="APLOnlineCompliance" loginUrl="~/Login.aspx" defaultUrl="~/Course/CourseViewer.aspx" />
</authentication>
When I log into the site I do see the cookie correctly being sent to the browser and passed back up: However, when I walk away for 20 minutes or so, come back and try to do anything on the site, the login window reappears. This solution was working for a while on our servers - now it's back. The problem doesn't occur on my local dev box running Cassini in VS2008.

I have a form on which there is a repeater control for showing records in a grid-like format. On the same page, if we click on edit row link, the details for that row come into view. After editing, we click the save button to save the data and return back to the grid [Note that all these controls are on the same page]
This process is followed for say 3 records.
After this, I would want to view only those rows for which the values have been changed (alongwith the old and the new values)
How can this be achieved? Can Datatable.getchanges() help in such a case? If yes, how? Or are there any other options that I could go for?

Is there a way to check the memory usage (consumption) of individual controls on a web form shown in a browser. Like Repeater Control, Multiline Text box etc. The reason is I am putting the repeater control in session and checking the status of controls, based on which I am doing further actions.

I want to redirect the user after 2 mins if there is inactivity for 2 mins. I am not using ASP.NEt membership. And I dont want to use Sessiontimeout for this. Session timeout will logout the user even if he is working on the system. My objective is like screensaver process.
If there is no action for the specified time, the screensaver runs. Similarly, I want to redirect the user to login page.
note that i have already handled it with the following javascript:
[Code]....
Here what my problem is,
the user is working on the site...ok.. he want to see someother site.he browse someother site and works on....or even he can do some other work in his system...but he is active in his system... What this script does is, it automatically logout the user and redirect him to login page. But it should not do while he is active...IT SHOULD REDIRECT IF HE IS NOT ACTIVE REALLY (Similar to Screensaver process)
Is it possible ?

We are upgrading the asp.net 2.0 web application to asp.net 4.0.
The application contain three main modules (sub application) like End User, Franchise and Admin with separate web.config, asp.net form Authentication, login page and running with single domain.
the URL like,
mydomain.com/login.aspx
mydomain.com/franchise/login.aspx
mydomain.com/admin/login.aspx
In asp.net 2.0, working fine with 3 sub applications with separate form authentication under a single domain name and also we can working with all threes in same time.
After the up gradation process (ASP.NET 2.0 to 4.0),
We didn't run all three applications in same times and also form authentication crossed.

I am trying to implement an ajax form inside of a jquery ui dialog.
I have a view with a button that opens the modal dialog form, makes an ajax call to an action that loads a partial view into the dialog. The partial view consists of a form created via Ajax.begin form. When I post the form I close the modal and update a div on my main page. This all works fine.
The problem is, the next time I open the modal and submit the form the http POST for the form is called twice. The third time I open/submit the form is submitted 3 times and so on...
It seems as if the submit button/form is bound multiple times and I cant figure out how to fix this.
Here is my code...
first the jquery call to load the ajax form partial view and create the modal...
[Code]....
here is the ajax form partial view...
[Code]....
and the js callback when the form is submitted

How would you calculate the hours?
Example:
05:00 15:00 = 10 hours
07:00 12:00 = 5 hours
12:15 to 14:30 = 2 hours 15 minutes.
