C# - How To Check A Input IP Fall In A Specific IP Range
Jan 26, 2010
If we let users input a couple of ip ranges, e.g., 172.16.11.5 - 100, how could I write a fucntion to check if a IP (172.16.11.50) falls in the ranges?
Is there any existing library in .NET to leverage?
I have a message (System.Web.Mail.MailMessage) whose body is 400 bytes long, nothing in cc or bcc, has valid to/from addresses. But when I get to System.Web.Mail.WebMail.Send(msg) I get the exception [HttpException (0x80004005): Value does not fall within the expected range.] Not sure where to look. Google only provided a handful of options, mostly related to CDO.
what is the best way to check today date come between from and To date. I am using below but it is taking too much time, but when i remove this condition it returns in 1 second.
getdate() BETWEEN a.ValidFrom AND COALESCE(a.ValidTo,getdate())
I have a table "RANGES" with the following columns
LowRange as int HighRange as int with the data similar to below select * from Ranges LowRange HighRange 1 100 101 200 201 300 . . . 901 1000
And another table "infoDetails" with the following columns
Range as INT amount as money with the data similar to below select * from infoDetails Range Amount 23 34.00 235 44.00 345 34.00 678 100.00 555 100.00 530 100.00 510 100.00 I need one report with the following format without cursor. LowRange HighRange Count Amount 1 100 1 34.00 101 200 0 0.00 . . 501 600 3 300.00 601 700 1 100.00
We are writing a feature that allows an administrator to block/allow ranges of ip addresses.
Is this easy enough to do with c#?
I was thinking of looking at each number [here].[here].[here].[here] and then mathing it with the ranges and just seeing if each number was between the two?
and i am facing problem while inserting the record.
eg:
if the room is already booked from 1st march 2010 to 10th march 2010.and if anybody is booking the same room from 4th march to 9th march it should show error message stating that
this room is already booked from 1st march to 10th march.
I have the following code. What's happening is, on postback, the required attribute for sequence will fire. If it passed, the range check is skipped completely. If it fails, it never gets to the range check either. Have I coded something wrong?
using System.ComponentModel.DataAnnotations;namespace Venue.Models{ [MetadataType(typeof(CategoryMetadata))] public partial class Category { } public class CategoryMetadata { [Required(ErrorMessageResourceType = typeof(Resources.Locale), ErrorMessageResourceName = "sequence_required")] [Range(0, 9999, ErrorMessageResourceType = typeof(Resources.Locale), ErrorMessageResourceName = "sequence_invalid")] public int Sequence { get; set; } [Required(ErrorMessageResourceType = typeof(Resources.Locale), ErrorMessageResourceName = "title_required")] [StringLength(256, ErrorMessageResourceType = typeof(Resources.Locale), ErrorMessageResourceName = "title_invalid")] public string Title { get; set; } }}
Starting to get frustrated with MVC and how everything is so helper based with one massive Html helper that just has everything in it. No more controls to inherit from, no events, nothing. I don't see what's the proper way to "customize" something. It's seems it take it or leave it or copy source code and start over again with yet more helper functions. And man, so much stuff in core mvc is internal or private so you end up copying a lot of code but then it won't work. I also don't see any events so that when the core helpers are generating an input element that I can hook in and customize there.
I'm trying to build a forms engine and I like all this new MVC 3 with data annotations, validation, etc. HOWEVER, for all my input controls I need to
1) Add javascript events for onkeydown, onchange, etc
2) Show validation errors using tooltips (was going to use a jqueryui plugin). Based on this, I really just want to place a Html.TextBoxFor and have it generate all the required validation stuff including it's own hidden ! to display should a validation error being present.
I'm using LLBL business objects so it's not so easy to go add attributes like [required] and stuff. Ideally, I'd like to layout the forms once, but then OUTSIDE the form, inside the helpers, or whatever method I use, there I can customize exactly how the input elements and validations are rendered. What is the easiest way to customize, hook, subclass, whatever, the current helpers so that I can generate input elements but with my own project's specific twists?
I have a page in MVC where i want to take the email adddress as the input which can be of format like:"Jone Davi" <jone@gmail.com>, "Ben Miller" <ben@gmail.com>, "Jane Ton" <jane@gmail.com>,
Then from this I want to parse the valid emailaddress.But on click of the submit button getting error message" A potentially dangerous Request.Form value was detected from the client" Thus is there any way to take the input of email address in above format and bypass the security error for that specific page.
I have a form that when submitted shows a busy animation and disables the submit button.
Anyone know how to query Microsoft's Sys.Mvc.FormValidation to see if the form passed it's test so I can prevent the busy animation showing if the form hasn't actually been submitted? Or even some other work-around? In case it's relevant - I'm using Data Annotations for my validation.
At present my client side javascript looks like this:
I have a Range Validator as follows. It is for restricting values between 1900 and 2070. However, it fires error when I enter a alphabet also. I want this to be fired only if the user enters integer values. How do I overcome it?
When using a range validator, if the user exceeds the defined range, How do you code it so it disables a button so the user can't continue. (without using JavaScript)
I am developing a page where i have a grid in content page (inherited from master page) which i am populating using DATASET in code behind like this here is the aspx.
[Code]....
As you can see i have some bound fields and one template field called "txtValue" which is the only input in gridview. Now what i want is when user input the value it should check the FACEVALUE and see if the entered value is not above the FACEVALUE and then need to Input value - FACEVALUE and result should be displayed in REMAINING field which is also a template field as label control.

I has developed a crystal report, which display the records from a table and filters them based on a parameter( date range parameter). now I has integrated the report into a asp.net page using c#, but when I am running the asp page it is not promption for the date range values, it used to prompt for date range when I run the report in crystal report.
