i think you want to store that data only in Dataset not in database. You can put that it quite simple .. How much data is present in the dataset ? (how many users data present in dataset a perticular instant ) if it is only one then you can change the data at any time ... Whats the problem are you facing ?
Thanks and Regards

Hello,
I have a website where customers can register for classroom training. After answering all the questions, I'd like asp.net to send a calendar notice to the users inbox. From what I've seen, I have to attach an ics file that represents an iCalendar. I'm successfully sending emails to the customers...I just have to find out how to add the ics attachment and set the parameters (e.g. remind the customer 24 hrs prior to training day, day of training, etc...).
My users are using Outlook 2003 and greater. I'm using asp.net 2.0. Any ideas?

Hi all,
I have a GridView (grv) that contain a HyperLinkField ( "MyLink" ).
I have a DataTable (dt) that contain data for GridView. ( I don't use SqlDataSource )
When i click "MyLink", "MyLink"'s NavigateUrl will be Default.aspx?id=param1&idU=param2.
How could i do that?

You can do it easily in Mygridview_OnRowDataBound event. While binding the grid this event fire on row level then just get the id & idU from other cell and build url string then set it to the Your Link NavigateURL.

Hi,
I am trying to develop an error handling in our asp.net web app. I'm pretty new to Master pages although the concept of master pages had been completed by someone else & works fine.
What I am trying to achieve is to have some code in the master page (I think this is where it will go) & this will need to handle any errors which occur in the content pages, I'm not quite sure what to do yet if there is an error in the BL or DAL? But, in the app_code folder I have a class (EventLogging.cs) which writes the required error, warning or information to the Event Viewer depending on the information passed to it.
So what I need help with is, how to implement the actual call to the EventLogging.cs - Can I do it in the master page or do I have to do it every time in each content page. If I can do it in the master page (which sound good to me) how can I check to see if an error has occurred. I've spent all afternoon googling & just getting deeper & deeper.
Any help would be appreciated.;)
Thanks

I'd be more inclined to write a base class which contains this functionality and make all my pages derive from that, so they are just there, not in the master page ( which you can't just call, AFAIK )

Hello,
I'm extremely new to ASP and a good portion of Visual Studio in general, I've only got experience writing form apps.
I need to write an internal webapp which a user can access to enter in data to begin a job in processing data via an sql server and images. Currently we have a similar service running on Java, but wasn't developed properly and causes the SQL server to eat up TONS of ram which requires constant restarting of the service. So I need(would like) to code a new one from scratch in C#.
Which project should I use, WebService or WebApplication project? What are the differences between the two?
With apologies for my newbieness,
Veralix

WebApplication.
Lord_Veralix wrote: What are the differences between the two?
A WebService is a library of methods that you call from another application. A WebApplication is a normal web site.
Lord_Veralix wrote: causes the SQL server to eat up TONS of ram
This is quite normal for MS SQL Server. By default it will use up every last bit of unused memory to maximise database performance. If you are using the server for anything more than a database server, you should change the settings in the database to limit the amount of memory that it will use.

FWIW, ASP and ASP.NET are two different things. ASP.NET is what you appear to be using, which is the right choice.

To use a third party web service in the site I need to use a special code to communicate with that web service . I dont want the user to be able to see this code in the source code of HTML. I also want to save the code as a javascript variable to communicate with the webservice using ajax. The special code needs to be stored on the browser of the user. How can I do this .
|
|

|

The only way you could do this, is if you define the variable, make an AJAX call, and return the value to set the variable. Then it won't be visible in the source, although anyone who wants to, can get it using Firebug or similar. There's simply no way to keep anything secret, if it's going to be client side.

Thanks for your reply.
Do you have any idea on how to deal with this ? How should I store the code no matter on the server or client.
One solution would be to encrypt the code , and decrypt it on the server . What class do u recommend for this ?( a class that make finding the code very hard )
