Re: which control is more faster repeater , data grid view, response.write etc

Data Adapters are slow, databinding is slow, data binding using DataBinder.Eval is really slow.

Get the data via a Data Reader, stuff it into a custom object, and then render the page using a repeater control without using DataBinder.Eval and I think you will notice a fair, maintainable improvement.

Also, how much data are you trying to display? Retrieve the smallest amount possible for the given screen and rendering only the required elements is another avenue for speed improvements.

Your main bottleneck will probably not be the repeater, response.write or gridview.

If you can, cache the data. I wrote an article with an easy way to do that http://www.codeproject.com/KB/aspnet/LookUpDataCache.aspx[^]

You main bottleneck will probably be the SQL query, not the serialization of the data.

Also, if you use the repeater or gridview's itemdatabound event that will be faster than setting the data in the mark up. Because the mark up has to use reflection to get the data type.

Adding parameters to the querystring would be a clean way of doing it, though it has its disadvantages.
Do:

function openwindow()
{
window.open("AssignedTickets.aspx?Param1=Something¶m2=somethingother",'window','width=630,height=620,background=silver,menubar=no, resizable=no')
}

Then in the code behind of AssignedTickets you can access these with:

string param1 = Request.QueryString["param1"];

var question = (_2b || !(_2b));

Oh, man...

var param1 = document.getElementById('textBox1').value;

obviously it doesnt have to be called param1.
Please read up on javascript, seems like you need it.

Good luck.

Oh, come on.
it's not my fault your control does not have any text in it.
Where are you declaring the param1 variable, anyway?
Where are you accessing it from?
Is your control's ID textBox1 ?

Either put some more code out here or google for it and figure it out yourself.
I really do recommend the latter, too.

Doesn't this say that SiteLevelCustomAuthenticationMethod is not returning something when it should ?

You have closed the while loop at wrong place.

Mechanism to handle user authentication and authorization

mukkanti00723-Feb-09 21:53

23-Feb-09 21:53

All,
I am looking for a mechanism which makes use of "Forms authentication" and "Role based authorization".

Requirement is
my application should validate users belonging to different groups "Admin,guest,developer" and each group may consist of no of users.

for ex: if i(developer) logs in with my id and pwd i should be redirected to web pages that are specific to me, likewise for admin and guest too.

i am considering option of storing credentials in sessions and fetch the roles from db for access.

Is this a feasible option.

can anyone guide me?

Thanks
Mukkanti

Simple activation email

Hello there
I'm having this registration form with 7 fields of real_name, user_name, email, password, city, webpage and signiture, I want my users to fill in this form and then after submitting the form I want to send them an activation email. my database has mentioned fields and also id (using identity) and verfy_user with default value of 0 (which means not).

2 questions are here for me:

1- how can I send activation email (simply?)
2- how can I prevent unactivate users from logging in?

your responses will be highly appriciated

Look up System.Web.Mail or System.Net.Mail.
There's loads of Smtp classes in there. And they're fairly simple.

Add a bit field in your users table (e.g. IsActive) and set it to true, when the user you're sending an activation email to clicks on the link in that email.

1. First user fill the registration form.
2. User Click on the submit button.
3. On submit button click, you send him a activation mail for his account.
Now Following is my suggestion for your question.

netsooz (Amir Hamidi) wrote:

Now, I will suggest, add one more filed called GUID in the DB. While sending the mail add the GUID with the corresponding user in the database and send the activation url.
Send a URL link with the email like
http://yourwebsite.com/Verification.aspx?Guid="AFDFASDFrwerwSDF@423"

Now, This GUID will ensure that, weather the user coming from the proper source or not. When user hits the URL, Read the Query String and verify the user GUID from the database. Now if its valid, then set the verfy_user filed to 1 and redirect user to Home Page.

netsooz (Amir Hamidi) wrote:

During login, Check verfy_user field along with the User ID and Password. If user ID and password matched but verfy_user is still 0, then throw a message that Please activate your account.

Hope this will helps you to move ahead.

Good luck.

Good answer, but just for the record:

filed - as in my glass has been filed with wine [sic]
field - as in my database field is "Username"

Don't worry though. Most English people get confused with these english words which sound (and often look) the same but have different meanings.
