does it mean that there is no Internet connection ?

I guess it's not specific to internet. It checks for a network connection which may include LAN too. The property he provided always returns true. Check documentation[^].

This has nothing to do with ASP.NET, through check System.Net.NetWorkInformation for more detail report. SystemInformation.Network always returns true !

why so?
i have run this code, its return true for both cases when my network plug is in and out .
|

Yes. This is what MSDN documentation says. I don't know why it is so. MSDN Says "This property always returns true on all Windows platforms supported by the .NET Framework. "

Looks like it just check for the machine has networking capability or not and not the network is present ot now.
May be this
System.Net.NetworkInformation.OperationalStatus has different status telling about the current network status
Unfortunately i dont have a machine that is not in n/w so cannot test.But MSDN confirms it is the one.

Why do you want to check this in an ASP.NET application ?

hi all, i have strange issue and it may be dumb question, i am using below code in asp.net 1.1 to generate the cookie it is generated on some computer using locale(En-us),but cookie is not generated on some computers which have danish locale.
My question "is cookie generation depend upon the locale/Regional setting/Language"
below is the code to generate
<br />
string strCVal="2001" + "@ENG"; <br />
for(int i=0; i<Request.Cookies.Count; i++){<br />
Request.Cookies[i].Expires=DateTime.Now.AddYears(-30);<br />
}<br />
try<br />
{<br />
Response.Cookies["SCID"].Expires=DateTime.Now.AddDays(-3);<br />
}<br />
catch{}<br />
HttpCookie aCookie = new HttpCookie("SCID"); <br />
aCookie.Values[strCVal] = strCVal; <br />
aCookie.Expires = DateTime.Now.AddMinutes(5); <br />
Response.Cookies.Add(aCookie);
that code does not throw any exception as well.
Regards.

whenever i try to add a class file , i get the following message.
You are attempting to add a class to an asp.net application .for a class to be generally consumable in ur site . it should be placed inside the app_code folder.Would u like to place the class in the app_code folder?
Why did microsoft recomended to add the class in the app_code folder?

app_code directory is added from .NET 2.0 onwards. Classes kept in the app_code directory are accessible to the whole website. When ASP.NET compiles, app_code and it's subdirectories will be compiled as a single assembly.
|
|
|
|
|
That means the class outside the app_code folder will not be accessible?

if you use website project template in VS2005, you won't be able to access classes placed outside app_code. Create a new class library project to the solution and put your classes there and refer this project output to your website.
If you use web application model which is like ASP.NET 1.1 model, then you are allowed to do this, AFAIK.

I have a login page where I have my own label and texboxes which take input username and password, and there is a function in which there is a SP which validates username and password stored in the database.
My code in Login.aspx.cs is such that I call that function and validates username and password and redirects to next page Page2.aspx.
Now I want my site to be authorized such that if a user tries to access internal pages he couldn't be able to do that.
I have code in my WEb.config for that is
<authentication mode="Forms">
<forms cookieless="UseCookies" timeout="525600">
<authorization>
<deny users="?">
<allow users="*">
and code in login.aspx.cs is
protected void btnLogin_Click(object sender, EventArgs e)
{
validateUser = validateUser.ValidateUser(txtUserName.Text, hashedPassword);
if (Page.IsValid)
{
if (validateUser != null)
{
Response.Redirect("~/Page2.aspx");
}
else
{
lblErrorMessage.Text = "Invalid User";
}
}
}
Now when I try to run internal pages without login it automatically redirects to login page which is fine but when I put valid username and password in the login page it redirects with some "ReturnUrl" and not able to redirect to the Page2.aspx page.This is my problem.
Can anybody tell me where I am doing wrong or need to change the code somewhere?
Thanks in advance,

Did you put your debugger in and step-through?

HI,
I am using update panel in my application.but i am facing one issue.
I have one page for new enrolment of members, and i have two user controls Step1.ascx and Step2.ascx. My functionality is that at a time olny one control is visible on the page and other will be hide. for eg when user fills all fields in step1 and press next button then step2.acsx will be be visible true and user control Step1.ascx will be visible false. all this happening at postback.
both control is under update panel to avaid post back during change of visibility.
On Step1.ascx i have one javascript variable var_pageName and its value is "Step1".
I want to update this value during post back to "Step2" when Step2 user control visible is true and vise versa. but the problem i am facing is javascript value is not updating during postback. I had tried this with scriptManager.RegisterClientScriptBlock and also with scriptManager.RegisterStartupScriptBlock by palacing it on both Usercontrol level and also on page level.
Please help as this is very urgent.

This is the FIFTH time he has asked this question!!!!!

using AJAX dowsn't mean that anyone can change the architecture of web application....
even in AJAX postbacks occur ! but they are not visible to user ....
and every postback will affect the server side controls and variables only.... how come you are supposed to update value of javascript variable to be changed ?
use SESSION variables instead ...
