I'm implementing captcha on my website like the one in [URL]. It is working fine while running on VS2008. However, not when uploaded on IIS. I think the image is being blocked by IIS.. anyone knows how to fix this?
how to refresh a image control to pick up the latest on a asp.net page. The problem is that i am not able to get the latest image on the page, it keeps showing the old page. But when i hit the refresh button on the toolbar it correctly gets the latest image and displays it in the control.
We are developing a web solution for our clients to handle their business processes. With reality in check, clients' requirements change over time; sometimes adding a new field, changing the calculation logic etc. When it was still a small scale solution, whenever an upgrade occurs, we will upgrade any existing data to the latest change i.e by having a empty property for it. I would admit this isn't the best of scenarios as old products that previously don't possess certain properties are now 'new' again which doesn't reflect the product correctly.
I am looking for a solution to introduce versioning to this solution before things get out of hand. What I've come up with is like this:
Realising that data is semi-structured (it changes from time to time), we've decided to go with an XML / XSLT approach. Storage of the data will be a mix of columns storing individual properties (e.g. ProductID, ProductName, VersionNumber) and XML columns that holds XML data to cater to fields that will change.
These XML and XSLT will have version numbers to tell the system which version of XML works with the other.Logic wise, we were thinking of developing our business logic to support multiple versions so that old products will still be calculated using old algorithms while new ones will use the new algo. For old products, besides updating them using the old algorithm, we will allow an 'upgrade' option so that they can be upgraded to the new version if they want to. Database wise will remain unchanged since we will store fields that are to be changed in XML form so extending fields should be catered for.
Would like you guys out there to comment on such a setup. I'm concern about performance since some fields are stored as XML, retrieving it will require extra steps, hence the reason why we decided some consistent fields should be on their own for searching purposes etc. Also, would doing multiple versioning like this get really big on the logic side as the program grows?
My client has few requirements for his website he want to built. want to discuss best practices to start this project and make this a learning experience.
accessible from all browsers and platforms. (mobile as welll)language supportscalableshould be CMS style so he can assign roles etc for editing. except above my question is what will be best to use as a new project in VS2010 (MVC, web application etc)
I am little confused regarding the concepts of localisation and globalization.I was working on a project which was totally database driven. All the data, images and flash stuff was coming from the database. Now the site is fully loaded with the data.Now the client wants the currently running site in 5 different languages. So I read the resource files concept. Now the confusion arises. I have 2 types data on the site, one is static(ie text on labels, titles, buttons) and dynamic data that was added from the admin panel.Now my question is: If at this stage I want to make the site in 5 different languages, then I have to make the resource files for all those languages so that the static data can be displayed in different languages.But what about the dynamic data that was entered by the client. Client uploaded huge amount of data. Should I make the changes in the database tables and add 4 other columns for different languages and again upload that much data in those 4 languages.
