• Disable Internet Explorer 8 Developer Tools

  - by Steve Brouillard

  Is there a way to either disable Internet Explorer 8 Developer Tools, or at least change the shortcut key mapping? I'm working on an ASP.NET AJAX app that has used the F12 key for a function for years (it's actually a hold over from the original DOS app). Customers have used this key for the sam function for nearly 15 years and we'd really like to avoid having to move that function. Cheers

• OK to throw an error for a missing required querystring parameter?

  - by Balazs

  Is there anything wrong with having an asp.net page throw a (custom error) if a a required querystring parameter is missing and having global.asax catch it with Application_Error, then transfer the user to an error page? I have several base classes that perform these checks and I am not sure of the best way to communicate the error to a user. So, something like this: int reqParam; if(!isParamSet("myReqParam", out reqParam)) { throw new QuerystringParamMissingException(); } which is then caught by Application_Error in global.asax.

• Using WebSockets in a C# Web Application?

  - by sixones

  I know its possible to use WebSockets within C# using a console application running along side the web application but Im wondering if its possible to use the requests on the C# web application to create the WebSockets. I've been looking through ASP.Net and Im starting to think it wont be possible unless I use straight up C# and create my own HTTP server and then use the same socket object to generate Web Sockets (similar to the way Node.js and Socket.IO work). Any thoughts on ways to include WebSockets on a C# web application without having multiple servers / projects?
