  • Why can't I write just a try with no catch or finally?

    - by Camilo Martin
    Sometimes I do this and I've seen others doing it too: VB: Try DontWannaCatchIt() Catch End Try C#: try { DontWannaCatchIt(); } catch {} I know I should catch every important exception and do something about it, but sometimes it's not important to - or am I doing something wrong? Is this usage of the try block incorrect, and the requirement of at least one catch or finally block an indication of it?

  • How could I insert a string into the response stream anywhere I want?

    - by DM
    There may be an easy way to do this but I can't see it... I created a simple Http Module that starts a timer on the PreRequestHandler and stops the timer on the PostRequestHandler to calculate the time it took the page to load. I then create some simple html and write my results to Response.Write. Since I'm doing this in the PostRequestHandler it's adding my results after the </html> tag. That's fine for testing but I need in a scenario where the page needs to validate. I can't seem to figure out how I could manipulate the Response object to insert my results before the </body> tag. Response.Write and Response.Output.Write don't have that flexibility and I couldn't see a way to work with the Response as a string. Am I missing something easy?

    Hi, I have 24/7 service which keeps setup (configuration data) for charging, routing and etc in the Sql Server. Once it is started it loads the data from table using Linq2SQL and use the data through all the application. And we need a solution to update the setup data in the table without restarting the application. So I am interested is it possible to catch/determine that the table was updated so I can refresh the setup data in the application. I mean is it possible to have events which will raise when there is any delete, update or insert on the table. Thank you.

  • set label text to total row count of gridview

    - by woolardz
    I'm using a stored procedure in a sql database as the data source for a SqlDataSourceControl on my .aspx page. I'm then using the SqlDataSourceControl as the data source for a gridview on my page. Paging is set to true on the gridview. What i would like to do is set the text of a label to the total number of rows in the gridview. I can use this code 'labelRowCount.Text = GridView2.Rows.Count & " layers found" to return the number of results per page, but it doesn't give me the total. I've looked in several places and haven't been successful in finding a solution.

  • How do I generate a RouteLink to a route in a different area?

    - by Max Schmeling
    I have two different areas, and I have a route in one of those areas that is specific to that area, but I need to generate a link to that route using Html.RouteLink from another area (it's how you get over into the new area) but it won't work... It doesn't seem possible to use RouteLink to routes in a different area. What is the best way around this? Should I just define a new route in the other area and name it differently?
