First of all wishing you a happy and prosperous New Year!!
Hoping that your image creation is working well, just assign the value shown in the Captcha into a session variable. This session variable should be reset or assigned new value each time the script is executed.
That's all my suggession.
If you want a script to generate the Captcha then, is as if doing the full job.

I have an application where I need to get Request.ServerVariables("LOGON_USER") and it is not returning a value. I have googled and found several articles that say I need to go to Directory Security -> Authentication and access control and uncheck "Enable anonymous access" and check "Integrated windows authentication". I have done this and even tried restarting IIS. I have also gone to Internet Options->Advanced in IE7 and made sure "Enable Integrated Windows Authentication" is checked.
These are the things I have found from searching but I have done them so what else have I forgotten? Thank you for any help.

I am not an admin of my office PC. I have IIS installed, but as i do not have admin priveleges I cannot create a virtual directory.
Is it very necessary that I should need IIS to run classic ASP page on my machine.
When i opened it in VS 2005 and try to run this, It says an error,
This type of page is not served.
Any help would be appreciated.

Hi everybody,
First of all: best wishes for the coming year!.
Unfortunately I am still working on this last day of 2008, and hope someone else is too....I am building a website for a company that does inspections on seagoing vessels. They produce reports of these inspections and want to make those reports available to the customers through their website. It is obviously no problem to provide a login to a restricted page for a particular customer, on which he can see a list of the reports (pdf files) he can download. I am using php for this. However, should anyone know the location and the names of the relevant files, this would enable them to download the file by just entering its url, bypassing my beautifull login script (I can protect the php page against showing without login, but the pdf files themselves obviously do not have any coding that allows to protect them)
Does anyone have any idea how to make sure that the downloadable files can only be reached through my php page and not directly through their url's?
Thanks in advance.
William

You would need an IIS handler to map the file type to and process the request, where you could check for authorization, before displaying the file.

as mark replied, you need to be admin of system.
But there are another ways to protect your files to some extent. I am not a php developer, so i cannot help in code part, but i can suggest you the ways that we use in .net for security.
1. Do not give the direct link for download to user. Hide the link and push the download from the server. e.g. as the software download is pushed by downloads.com.
In .net we use 'Response' method for the same.
2. Protect your PDF files with password. This is also one security concern.
3. Don not give the download from site. Just send the attachment in mail to the user who requested it.

1) If the file is exposed it will be available to anyone with enough time and interest in retrieving it
2) Possible, but how you give out password?
3) Impractical. I want to read the pdf now, not later in an email which can be delayed or blocked by spam filters. If the user is traveling and and doesn't have access to email how would they read the file? Wait until later?

You may use these methods, but I certainly wouldn't, with the exception of #2.

1. When a download is pushed from the server the file complete path is never exposed. It is from the page that is being opened, but a threat level is always there.
2. He has not defined that the PDF will be generated by System or manually. If manual, then it can be password protected, before being uploaded to server.
3. How much time it takes to send a mail. Hardly a minute or two or five. For security it does not matter. Regarding spam, the address can be added in Contact List. Last, if the User is traveling, and can access the website, but not mail, how is this possible(IF there are firewalls, or proxy's).
There is also a fourth option in .net,i.e., if you have used the rapidshare.com, it does not start the download even if you typed the complete path of file in address bar. I can implement that in .net, but have no idea of php.
Securing a file little is always better than leaving it in open. Atleast the person who is interested, will have to do the extra workout.

Email is not a practical solution for a number of reasons.
Amandeep Singh Bhullar wrote: How much time it takes to send a mail. Hardly a minute or two or five.
That's the point, time. A user wants to view the file immediately, that's why they clicked on the link. Email may not be available, think of a kiosk situation.
Amandeep Singh Bhullar wrote: Regarding spam, the address can be added in Contact List.
So you're saying that to look at the file I must know the email address of the sender and add it to the white list before I can receive the email and view the file I wanted.  
Amandeep Singh Bhullar wrote: Last, if the User is traveling, and can access the website, but not mail, how is this possible
how is this possible? You can't be serious. Apply a little thought processing.

Email is not the perfect solution, i agree with you. I just suggested him the one way.

Store the files outside the site document root (write-protected).
Your code should check for logged in user.
You may code a script for fetching the contents of the downloadable file and also storing it in a file on the fly and render it. This Should solve the purpose.

Do not store the files in the directory instead store them in the database.
Have a look [^]

Hello Everyone
I am using a drop down list in asp.net 2.0
What i want to do is, user will not select the states but user can select the cities in that, means, according to that country, cities will be listed in same drop down list.
Regards
Saurabh agarwal

I believe , you are using database for that. so in a Dropdown list just read all the States name , when user select state name from dropdown, just create simple query which will retrieve the city name based on states and bind them in a dropdown list.
cheers,

Try using the below code to export the Grid to XLS, its working fine for Now.
Response.Clear()
Dim abc As String = "attachment;filename=Outbound.xls"
Response.AddHeader("content-disposition", abc)
Response.Charset = ""
Response.Cache.SetCacheability(HttpCacheability.NoCache)
Response.ContentType = "application/vnd.xls"
Dim stringWrite As New System.IO.StringWriter()
Dim htmlWrite As New HtmlTextWriter(stringWrite)
Dim frm As New HtmlForm()
Controls.Add(frm)
frm.Controls.Add(GridView1)
frm.RenderControl(htmlWrite)
Response.Write(stringWrite.ToString())
Response.End()
|
|
|
|
|
this gives the following exception at the line
Controls.Add(frm):
The Controls collection cannot be modified because the control contains code blocks
|
|
|
|

i have used the original code in two different pages to export grid to excel.
its working fine in one where the grid is not inherited control where as in the other its inherited and not working
|
|
|
|
|
the issue is always there when you try it with the inherited grid
|
|
|
|
|
So is there any solution to it
