Sharepoint Server - Cannot Use Web part

[asiruvur]

Hi,

I recently started working on Sharepoint Services. I developed a webpart and tried to import it on my site but the error message says:

"A Web Part or Web Form Control on this Web Part Page cannot be displayed or imported because it is not registered on this site as safe."

I have googled a lot to find the solution. Every where it says change the SafeControl in <localfolder>:\inetpub\

http://wwwroot\web.config

but I couldn't find the web.config at that location.

I tried changing the web.config @
G:\Program Files\Common Files\Microsoft Shared\web server extensions\60\CONFIG\web.config

but no use

I'm running both Sharepoint Services and Visual Studio .net on the same machine. When I created the assembly it was not strong named. Does it make a difference.

Any help is appreciated
