ASP.NET: How to create a custom error page.

ASP.NET has this useful feature that you can set a custom error page. Whenever an error occurs in the system, you are automatically redirected to the custom error page. By using this feature you can avoid showing the ugly yellow page and the error details to the user. How to implement this? Well the following link has described it all in details. :)

problem installing vlc in fedora; Having errors like : Error: Missing Dependency: libcucul.so.0......

I was trying to install vlc player in fedora 10 using yum. As I entered the command from terminal:

yum install vlc

I saw a long list of dependencies that ended up showing a lot of error messages of the form :
Error: Missing Dependency: libcucul.so.0. .....

I was able to solve the problem in the following way:

I rebuilt the repository database by the command:

rpm --rebuilddb

It did the work for me. Probably my yum repository database became errorneous by some changes. When I rebuilt it with the command, it loaded the database information once again from the scratch and the problem got solved.
