Check For The Existence Of Images On A Remote Server?
Jun 24, 2010I have a website which loads images from a CDN. I have a requirement to check for the existence of 100s of images on the CDN.
I am using this code to achieve this:
Protected Function RemoteImageExists(ByVal Path As String) As Boolean
Dim httpRequest As HttpWebRequest = CType(WebRequest.Create(Path), HttpWebRequest)
httpRequest.Method = "HEAD"
Try
Dim httpResponse As HttpWebResponse = CType(httpRequest.GetResponse, HttpWebResponse)
Catch ex As Exception
Return False 'Undesirable flow, but seems unavoidable :(
End Try
Return True
End Function
This is still very slow, and many requests timeout. Is there a faster way to do this?

Jan 16, 2011I am using asp.net membership provider in one of my database which is working perfectly fine. However, I have another database which doesn't have the asp.net membership provider enabled (I don't mind using the provider in this as well).
1. Now, I need to integrate both the database such that the user from both the database can log in from the same application without specifying the database name. How may I achieve this?
2. During registration, I may need to create user on the both database ( since the user doen't specify the database name)
I cannot use a single database for storing all the users !

ADO.NET :: Checking Existence Of A Record In Sql Database Using IF EXIST And Reporting Outcome On Asp Page
Sep 22, 2010I have a page that inserts a record to an sql database and I would like to do the following:
(i) Check if a record already exist before trying do an insert
(ii) If a record exist, the page should be able to inform/display a message in a textbox informing the user that the record already exist.
I have seen a number of post on the internet that suggest that one possible solution is to write a sproc and use the T-sql IF EXIST function. However, I have NOT seen a complete code showing (a) how this can be done (b) how to call the sproc from an asp page (c) and MORE IMPORTANTLY how to display a message informing a user that a record already exist i.e. when the record already exist in the database.
Would Enumerating Folder Contents And Checking Existence Of Several Files On Each Web Request Be A Serious Performance Penalty
Feb 14, 2011As an extensibility option for my web application I would like to allow the user to add sections to it by simply making new folders and uploading files to them. So, for instance, if they created (in the webroot): /UserContent/StaticPages/First/Second/index.txt. Then in the main menu there would be a new menu point "First" with the submenu point "Second", which would lead to markdown-parsed version of index.txt. This way the user can upload any static menu points he wants (such as "About us", "Contact us", "Our Mission" etc.) Another extensibility point is that I would like them to add headers/footers to specific webpages in a similar fashion. I'm using ASP.NET MVC3, so there are pretty URLs, and it would be easy for the user to just create: /UserContent/Additions/Store/Categories/35/header.txt
And when someone opened [URL] the markdown-parsed header.txt would be prepended. This is simple for the user, and simple for me (I don't need to make sophisticated admin panels and WYSIWYG editors). However I'm worried about the performance. This scheme means that on each GET request I would need to scan the /UserContent/StaticPages folder and check for the existences of the header/footer files (several, because parent levels can have their header.txt/footer.txt as well).
I could cache the result, but then I have to manage the cache and the user will need to know that changes can take up to X minutes to display. Would this be a premature optimization? There won't be much data in those folders, so Windows will probably be able to easily cache their contents itself.

C# - Administer Website (create New Users, Assign Users To Roles, Etc.) From A Windows App?
Feb 9, 2010I have an asp.net web app that uses forms-based authentication, a SqlMembershipProvider (using an encrypted password format), and a SqlRoleProvider. I need to know if it's possible to administer the users (create new users, assign them to roles, etc.) from a windows application - the powers that be don't want any administrative functionality in the web app itself.
Here is the membership provider definition from web.config:
[code]....
So, obviously, I have a Sql Server database that contains the users and roles for the web app. I'd like to create a separate windows app that references the web app assembly, and use the configured MembershipProvider, RoleProvider, and machineKey to create users, assign users to roles, etc. If that's not possible, I can duplicate the configuration settings from web.config within the windows app. But I don't know how to do this either.
Web Forms :: Stop Users Users Using The Browser Back Button And Potentially Submitting An Old Version
Mar 25, 2011I need to stop users users using the browser back button and potentially submitting an old version of a form.
I'm storing a guid in a session variable and also writing the value to a hidden form field and then checking the session value against the hidden field value if a user does try to navigate back and submit an old form.
If the form is submitted and the user wants to complete a new copy of the form then a new guid is generated both to the session and to the hidden form field. Now, if the user decides to hit the back button a few times to get the old form and tries to submit it again, the page checks the current guid in session against the guid stored in the form field and it finds a mismatch and prevents the form being submitted.
This works as expected in Chrome and Firefox, but in IE6, when the user hits the back button to view the old form, the new guid value appears in the hidden field of the old form! This means the user can submit the old form again, which we definitely do not want.
