Re: Remember me Cookie - ASP.NET Discussion Boards

HI All
can anybody tell me how to find substring count occurs in a string in asp.net C#.
for example..
string str = "Ram was not there. Ram has been gone to market";
if I wand to find count of "Ram" in this string , then it should return 2

please help me..
thanks

//Function to count no.of occurences of Substring in Main string
public static int CharCount(String strSource,String strToCount)
{
int iCount=0;
int iPos=strSource.IndexOf(strToCount);
while(iPos!=-1)
{
iCount++;
strSource=strSource.Substring(iPos+1);
iPos=strSource.IndexOf(strToCount);
}
return iCount;
}

Thanks eyeseetee.

This is a C# question. The easiest way probably is to call the split method and see how many elements it returns.

Please can you explain exactly what your problem is

Hi all...
I have a login form (username and password), and I want to add a checkbox (remember me), how can I perform this cookie?

Thanks alot

This article shows you how to implement the above functionality in ASP.NET.

Step 1: Add a checkbox in the login page
You can add a checkbox in the login page by dragging and dropping a checkbox from the toolbox when you are in page design mode, or you can create a checkbox programmatically in the code behind class.

The following code shows you how to do this in the second way:

private CheckBox _rememberMeCheckBox;

//.....

this._rememberMeCheckBox = new CheckBox();
this._rememberMeCheckBox.Text = "Remember me next time");
this._rememberMeCheckBox.Checked = true;
this.Controls.Add(this._rememberMeCheckBox);

//.....

Setp 2: Creat a cookie when a subscriber login
create a cookie in the Cliked event handler of the login button:

private void _LoginButton_Click(object sender, System.Web.UI.ImageClickEventArgs e)
{
//....
//....

ApplicationUser user = ApplicationUser.RetrieveCurrentUserByLoginId(userId);

if (user != null && user.Password == password)
{
Session["user"] = user;

Response.Cookies.Remove("CookieFromXXX");

if (this._rememberMeCheckBox != null &&

this._rememberMeCheckBox.Checked)
{
HttpCookie cookie = new HttpCookie(string.Format("cookie_from_{0}", this._host));

cookie.Values.Add("userId", user.Id);
cookie.Values.Add("pwd", user.Password);
cookie.Expires = DateTime.Now.AddYears(1);

Response.Cookies.Add(cookie);
}
}

//....
//....
}

Step 3: Override the OnInit method in the base page
If there is a base page which is the parent page of all other pages in your website, you can override the the OnInit method in the base page like the following code:

override protected void OnInit(EventArgs e)
{

//....
//....

if (!IsPostBack && Session["user"] == null)
{
if (Request.Cookies["CookieFromXXX"] != null)
{
HttpCookie cookie = Request.Cookies["CookieFromXXX"];

string userId = cookie.Values["userId"].ToString();
string pwd = cookie.Values["pwd"].ToString();

ApplicationUser user = ApplicationUser.RetrieveCurrentUserByLoginId(userId);

if (user != null user.Password == pwd)
{
Session["user"] = user;
}
}
}

base.OnInit(e);
}

Or you can add the above logic in the OnLoad method in the home page.

Step 4: Use the Session["user"] to determine the subscriber logged in or not
In any web page, you can check the Session["user"] to determine the subscriber logged in or not, see the following code:

if (Session["user"] != null)
{
//logged in already
//....
}
else
{
//haven't logged in yet
//....
}

Step 5: Expire the cookie when subscriber logout the website
Add the following code to expire the cookie when subscribers logout the website.

this.Session.Clear();

if (Response.Cookies["CookieFromXXX{0}"] != null)
{
//Response.Cookies.Remove("CookieFromXXX");
Response.Cookies["CookieFromXXX"].Expires = DateTime.Now.AddDays(-1);
}

Response.Redirect("./homepage.aspx");

could you please write it using VB.NET
Thanks alot

Hello friends,

I have created my first application in .Net 2005 but i am not able to find the .dll file.
Can anybody tell me where the .dll file of the application get saved?

Thanks,

It doesn't, by default in VS2005 your pages are compiled the first time someone requests them.

Hi All

I have the following element

<span id="Label2" style="display:inline-block;border-width:1px;border-style:Solid;width:200px;">Label</span>

(Actually this is the output of the ASP.NET Label Server Control)

I get two different outputs when I use IE and when I use FireFox browsers.

Has Anybody seen this.?

Thanks

Odd that an ASP.NET control would not adapt, but different styles from the same css between browsers is common.
