In order to maintain user uploaded images in website becomes very tough as the number of images are increasing. In the long run the available disk space will come to 0 bytes.
Amazon generally provides unlimited space for their S3 service. If we want to provide unlimited space to our website what are the possible ways?
i'm writing a stored proc and if a field i return is longer then 200 characters, i want to truncate, find the last space, remove any characters after that space, then add some full stopseg:
INSERT INTO @rec(articleid, abstract)
SELECT a.id,
CASE
[code]...
How to replace a character in a String to space or white-space?
View 3 RepliesI have a problem with DataSet.GetXml() in ASP.NET 4.0:
First I populate the dataset with some tables.
Then I run the .GetXml() method on the dataset and some XML is returned. The output of this method is not want I want it to be, however.
The desired result is this:
[code]....
How do I stop this from happening? I mean, how do I stop the cell from being included at all?
In ASP.NET 1.1 the same code is used and the desired output is returned. This means that it is probably some new thing in 4.0 that I have to switch on/off. But what?
What i want to know is:
If i don't include maxinvlaidpasswordattemps in web.config i get unlimited attempts?And also what is the maximum limit i can have for the attempts.
I have created an ASP.NET Intranet Application in framework 2.0.
I have deployed this application on my Local Intranet Server and client are accessing the application in thier browsers. What is happening is that i have set session timeout value to 90 mins but it still move to redirect page after 5 or 6 mins inactivity.
My requirement is whenever a user logged in the application, the application should never go on the login page back, bu when user clicks log out button then it should redirect on login page.
My code is below in web.config:

I'm writing an ASP.NET app. I need to include a page where the user can add an item which has several sets of subitems, each of which sets is unlimited in number. The subitems themselves contain between 10 and 15 fields, so need a fair bit of UI space.
As an example of what I mean, the user needs to be able to add a Business record to the system, including any number of Employee records and any number of Asset records.
The way I normally do this is by using a MultiView control with a set of tabs at the top. The tabs switch between the Views of the MultiView. The first tab will be for the Business record, the second will be for Employee records, and the third for Asset records. The Views for Employees and Assets are initially empty bar a button to add a new Employee (or Asset). When this button is clicked, the page is posted back and a user control is added dynamically to capture the details of the Employee (or Asset).
There is one save button that saves the whole object graph to the database.
This is quite complicated to program and maintain and I usually encounter headaches to do with managing ViewState for the dynamic user controls. Obviously, the ViewState on the page can also become quite large, making the page quite slow.
The advantage is that it is quite an intuitive UI for the user to understand, and the user can add everything and check it all before saving anything to the database.
[RegularExpression(@"S*[a-zs]S*s*", ErrorMessage = "Please add
category name letters only")]
This works fine if I input some words something like this...test test. But if I try to do this... test test test, I will get the ErrorMessage that I implemented. The thing is that I don't know how many words are going to put in by the end user. Is there a way where unlimted whitespaces could put in place? I am using VS2010

how to do an amazon lookup similar to this, http://blogs.msdn.com/b/coding4fun/archive/2006/10/31/912260.aspx, I would just use this, but it seems to be out of date and the source is no longer available. Ideal What i would like to be able to do is look up items on either keyword such as "star trek" or straight up UPC. What I would like to get back is title, description, year, and a link to an image, type (dvd, books, music).

View 2 RepliesI have to create a web app (in C#) that's gonna let my users upload their files straight to Amazon S3 (not enough bandwidth on our own server). It looks like the only way i can do that is posting a simple HTML form to Amazon. The problem is that i have to do some work on my server too, like renaming the files, setting up flags on db when file is uploaded, and so on. I really can't see how to do that without uploading files first on our server, which is out of question, so other solution for this? Amazon S3 forum is pretty poor on this topic.

View 4 RepliesA few years ago, when first being introduced to ASP.net and the .NET Framework, I built a very simple online file storage system.This system used Rijndael encryption for storing the files encrypted on the server's hard drive, and an HttpHandler to decrypt and send those files to the client. Being one of my first project with ASP.net and databases, not understanding much about how the whole thing works (as well as falling to the same trap described by Jeff Atwood on this subject), I decided to store freshly generated keys and IVs together with each file entry in the database.
To make things a bit clearer, encryption was only to protect files from direct access to the server, and keys were not generated by user-entered passwords. My question is, assuming I don't want to keep one key for all files, how should I store encryption keys for best security? What is considered best practice? (i.e: On a different server, on a plain-text file, encrypted). Also, what is the initialization vector used for in this type of encryption algorithm? Should it be constant in a system?
User images - database vs. filesystem storage
Where should i store photos for a facebook-like app ? locally on the server in a folder or upload them to a database ? I am not intending to make this app commercial .
Currently I am looking to move my websites images to a storage service. I have two websites developed in PHP and ASP.NET.
Using Amazon S3 service we can host all our images and videos to serve web pages. But there are some limitations using S3 service when we want to serve images.
If website needs different thumbnail images with different sizes from original image, it is tough. We have again need to subscribe for EC2 also. Though the data transfer from S3 to EC2 is free, it takes time for data transfer before processing image resize operation. Uploading number of files in zip format and unzipping in S3 is not possible to reduce number of uploads. Downloading multiple files from S3 is not possible in case if we want to shift to another provider. Image names are case sensitive in S3. Which will not load images if image name does not match with request. Among all these first one is very important thing since image resize is general requirement. Which provider is best suitable to achieve my goal. Can I move to Google AppEngine only for the purpose of image hosting or is there any other vendor who can provide above services?
