Basic measures when building forms that interact with the sql database. What are the security measures (check insert strings, sql injection etc), and Do people use special controllers in order to format their data? I am using GridView and realizing its tables, which I dont like. If so are there any suggestions for data formatting controllers?

I have an idea of how to do what I have in mind, but I would prefer to ask for some advice just in case anyone can think of a better way.The idea is a simple application where administrators can upload any kind of file. Once the file is uploaded, they give out a username and password to a client, and the client will then access a private area where they will be able to view specific files available for them. ALL THIS IS DONE. My question is... because the browsers can process certain type of files (for instance a JPG or a PDF), they won't automatically prompt the client to save it on their computer, and they will open int he browser. I have solved this issue before by adding a few lines of code to the Response and modifying the content type, something like: Response.Clear(); Response.AddHeader("content-disposition", "attachment;filename=logo_large.gif"); Response.ContentType = "image/GIF"; Response.WriteFile(Server.MapPath(@"~/logo_large.gif")); Response.End();However, that would mean I'd need to change the content type for each file (JPG... GIF... PDF ... WORD FILE). So I'd need to find out the content type for each one, and dinamically change it. This way it would force the download for all files. Now... is there an easier way? Remember that I need to have many different type of files, if it was only JPGs for instance, it would be easy.

View 4 Repliesinstead of using gridview to insert student marks (I have hundreds of students) thought I used the Excel:
1) allow managers of each module after authentication to download the excel file (containing the students enrolled in the given module), the excel file ted is generated by the following code: Id_student ____ maks of subject1 -------- ----maks of subject2
[Code]....
But in this code I do not know how to:
* Add the following condition: the student'marks is between 0 and 20.
* Calculate the average of this module : sum (coeff * mark) / sum (coeff)
2) Allowing responsable module send me the file containing the data (but then I do not know how)
3) Using data, by sending them to the database to calculate averages.

View 2 RepliesI looked at Google's, but my boss shot it down because it involves adding a script to every page you want to track. I keep searching the web, but the stuff I am finding seems to be crap or not work all together. This is mainly for internal sites, not external. Seems liek a lot of the stuff I am finding want to give me remote statistics to a publically available site.
View 3 RepliesI work for a small E-Commerce shop and we are looking for a process that will handle resizing our product images dynamically. Currently our designers take high resolution photos, either provided by the manufactures or created in house, and alter them to fit various pages on our site. The designers are constantly resizing, cropping, altering compression levels, etc., of each product photo to fit the needs of the business. Being that our product line is updated frequently, this becomes a monotonous task.
Abobe Scene7 does exactly what we are looking to do and the images are served up from a CDN. Unfortunately we found it to be too expensive.
I'm curious to learn how others handle this process at their organizations. Does anyone know of any good 3rd party tools or other SAAS providers that can handle performing some basic image manipulation and serving them on the fly?
I've followed the standard example of in
http://www.asp.net/ajax/ajaxcontroltoolkit/samples/autocomplete/autocomplete.aspx which demonstrates using AutoCompleteExtender. Everything works fine but the auto-complete appears with about 20 pixel distance below the bottom of its target control. I mean they are not glued to each other as they should be. I've not changed anything and also I've not applied any special styling using CSS or anything else. why this ugly distance is formed while the control is rendered.

I have a String that contains the following: ?workarea=London+&+Home+Counties+Ltd&sub=fs&&&FASh*5which resembles a URI query string. What is the best way to parse the elements of this string (workarea and sub) without messing about with string manipulation?If I use HttpUtility.ParseQueryString is gets stuck as both elements include &. However if I encode the whole thing first I lose the seperations of the elements. Ideally the output would be:workarea = London & Home Counties Ltdsub = fs&&&FASh*5

I am having a lot of trouble with WCF web service over SSL / HTTPS, so I was wondering if (as a quick fix) I could serialize the object, convert that to a byte array, encrypt the array, pass the encrypted array.
On the other side receive the encrypted array, decrypt the array, convert from the array and then deserialize the object.
I'm completely new in web service. I want to study about it and the use it in my web site?
