Where is the code where you try to use My.Computer?[/QUOTE]
any code. normally if i type eg system. vs2008 will offer autocompletion. it doesn't do this for a lot of the common libraries on my system like "My.Computer.FileSystem" (or other my.computer....) and system.data.etc...
Which error message do you get?[/QUOTE]
Name "My" is not declared
system.data: data is not a member of system
If you're sure everything is well, try to re-install the .net framework!
I tried to uninstall 3.5 and vs.net2008 and then installing them again, but no luck there :(
