C# - Prevent Users From Modifying Date In Textbox?
Aug 4, 2010
I have a textbox with a calendar icon next to it. When the icon is clicked a popup form displays the calendar control. I have it set up where they can only select the week ending date(saturday) and that date is displayed in the textbox.
I want to prevent users from editing the textbox. I've tried using the readonly and enabled properties but that doesn't work.
How can I keep users from modifying the date in the textbox?
I am trying to prevent users from submitting ascii codes in a textbox using a RegularExpressionValidator.
This works fine and I am able to display an error.
However when the user clicks on another button on the page I get the "A potentially dangerous Request.Form value was detected from the client" error. Is there a way to prevent this?
i want when user click on submit button then a div layer will be generated over the textbox whose height and width will be just the same as textbox and in this way textbox will be blocked for entering something. i want to do it by javascript. in this scenario other textbox will not be blocked.
I have a textbox with a calendarextender and if I type in a partial date it automatically fills in the rest of the date with today's day/year. For example, if I just type in 5 and hit tab, it will fill in 5/23/2010. How can I prevent this from occurring, so that when the user tabs out of the field, only the numbers they have typed in will remain, and trigger some validation?
I am trying to restrict the data in the report with the use of a start date and an end date selected from a textbox (w/ ajax calendar extender)
should this be done on the report side or should i create a stored procedure and pass the variables to the stored procedure by microsoft report viewer.
It seems like there is two connection strings to the database, one for the report and one for the report viewer, is this correct?

I am making a small file hosting website, and each user can upload multiple files, and will have access to just his files and can't access others files, for example by guessing the URL. Is there a way to secure files to have access by just the owner and no body else "may be website administrator also will have access"
I have a folder within my website called 'ProtectedPages' which contains pages which users can only see if they have logged in (MyAccount.aspx etc). If they bookmark that page and try to go to it without logging-in, they are immediately bounced to my login page.However, if I have text files, images etc. in there, then it seems users can get to these fine without the need to login - all they need is the URL. For example, I could send the URL http://mysite.com/ProtectedPages/MyAccount.aspx to a friend and he wouldn't be able to access it until he had logged in. However, I could send himttp://mysite.com/ProtectedPages/ATextDocument.txt and it would show it to him without any problems.How would I go about protecting ALL files within this folder? I have a web.config file within the ProtectedPages folder which just has this information in it (I don't want TrainingAdministrator's to have access to that folder at all)
I am using ASP.NET profiles with allowAnonymous="true". I am NOT using ASP.NET membership. I recently took a hard look at the aspnetdb database and noticed that although my site gets 600-800 unique visitors daily, there are 4000-5000 "users" being created in the database.
Clearly what is happening here is the users with cookies disabled end up creating a record for every request.
My question: How do I prevent user and profile database records from being created if the client doesn't support cookies or has them disabled?
How can we prevent non ahuthenticated users from like and dislike multiple times?one way : save Ip address in a cookiebut theres's two problem1. I heard Ip address isn't unique and changes frequently2. cookie can be deleted by userI'd .
I have a asp.net chech box control in the top of my page. I have a html table getting populated from DB on the page load. But, during the page load checkbox got rendered before the html table gets populated. So, the user is able to select the checkbox before the page completes the action and becomes unstable. My problem is, I couldn't disable and enable the checkbox after the page compltely loaded. As I tried this in the last line of Page_load event and also, using a Page_UnLoad event - no use. These events fired before I see the HTML table in my browser. Also, I tried in javascript (which is running after the html table populated), but there I could not enable the disabled check box.
i have create web application for school management system...bt when i run my webside...(my welcome page is defaul.aspx bt if i want to acces studentdetail.aspx then i only enter url and i get studentdetail.aspx)
in my asp.net_vb code web. there are 9 textboxes whcih is used for entering numerical/dates
first is lve.text in whicj numder is entered
second one is lvefrom.text
thirdone is lveto.text
when user fills (lve.text) 5 and enter 15 Jan 2013 in lvefrom.text then lveto.text should show 19 Jan 2013. i had posted this earlier and got reply which is mentioned below. this code below gives me 20 Jan 2013 instead of 19 Jan 2013.
tw text boxes lve.text (number filled) and lve from.text (date filled). when user enter a numder in lve.text and select a date fro date picker in lvefrom.text then lveto.text should show date selected in lvefrom.text + number of days in lveto.text (eg if number of days is 5 and date selected in lvefrom.text is 15 Jan 2013 then lveto.text should display 19 jan 2013. because the starting day is also counted in my case.
Protected Sub lvefrom_TextChanged1(ByVal sender As Object, ByVal e As System.EventArgs) Handles lvefrom.TextChanged Dim ObjLocDate As New Date Dim IntLocDays As Integer IntLocDays = Convert.ToInt32(lve.Text) ObjLocDate = lvefrom.Text ObjLocDate = ObjLocDate.AddDays(IntLocDays) lveto.Text = ObjLocDate.Date.ToString("dd-MMM-yyyy") End Sub
fourt tex box is pfx.text, fifth is pfx1.text, sixth is pfx2.text
when use filles pfx.text 3 then pfx1.text should display 12 Jan 2013 and pfx2.text should display 14 Jan 2013. these are the prefix for leave( as 12 to 14 Jan 2013 is prefix.seveth is sfx.text, eighth is sfx1.text and nineth is sfx2.text
when user fills sfx.text 3 then sfx1.text should display 20 Jan 2013 and sfx2.text should display.
