View 6 RepliesI am using System.Web.Caching.Cache in an assembly used by my website.
I have set some key expiration (absolute expiration) to be 10 seconds (just for debugging).
I have also set a callback upon key removal.
The problem is that I see that the cache is getting refreshed after something like 20 seconds and not 10.
I am using HttpRuntime.Cache for this.
I would like to show a code sample, which can shed more light:

I have a lot of requests that read my Web Config file (eg. variable = WebConfigurationManager.AppSettings["BLAH"]). I am wondering... Do WebConfigurationManager.AppSettings read from disk each time, or is it cached in memory. If it's read from disk each time then I guess I will need to move the variable to a static variable so as to improve my app performance...

View 1 RepliesWhen I attempt to store the current time of 'DateTime.Now' in a column defined as time in a table within an SQL database, I get an error message that says: Cannot implicitly convert type 'System.DateTime' to 'System.Timespan'.
I have no trouble storing the current date of 'DateTime.Today' in a column defined as date, but this column will not also store time along with the date. The date column has properties that indicate it has a data and system type of date with a Length of 3 and a Numeric Precision of 10. The time column has properties that indicate it has a data and system type of time with a Length of 5, a Numeric Precision of 16 and a scale of 7. Did I define the time column incorrectly for storing the time of day?

I am using visual studio 2005 on windows xp sp3. The website is stored on file system. I used subversion to checkout the code from the server.
Here is the issue:
When I run the application for the first time everything is fine. But when I makes changes in the application then I should just be able to see those changes by reloading the page in browser. But it's not happening. I have to stop the development server and re-run the application which will start a new instance of development server and now I can see the changes. This takes like 3-4 minutes and it's a lot of waste of time which I can't afford.
For my fellow developer who is here for a long time everything is just working fine. He can just modify the page and reload the page in browser to see the changes.
Reading some forums on web, I tried to clear the cache of my browser (IE, Firefox) and it's not working. So, it's not a browser's cache issue. It's related to cache in development server.
