New Project namespace [Resolved]

I've got a working Soultion in the folder My Documents\Visual Studio Projects\WindowsApplication7. I want this in another folder called PurpleSlips under Visual Studio Projects. I keep getting an error when I try to save as, change the root namespace from WindowsApplication7 to PurpleSlips, copy everything to PurpleSlips, etc. It's not finding the .vb file, I think. How can I change the location of the Solution and associated files? Thanks.
[edit] It appears to get all the files except the form design .vb file. The code file is there. When I compare the files in the two folders, it seems like they have the same files. And even weirder, when I try to open the project in its original folder, WindowsApplication7, I get the same error, even though I changed nothing in it. Even though I open the original, it defaults back to the new, faulty one. Aaagghhh![/edit]

Bad start . Clean up everything and start new project.

I managed to get the original working again by deleting and adding back files. So now my question is how to save the solution under a different folder?

Copy the the whole project folder to another place , rename the folder .

Thanks, I'll try that, but won't that mess up the namespace under Project -> Properties, as well as the .exe and .pfd files under the obj folder, which appear to take their names from the original folder, i.e. WindowsApplication7? I'd think a simple Save Solution as... should do the trick. This aspect of the IDE doesn't seem to be an improvement on VB6.

No. I tried to do 'Save solution as' to different folder . It saves and write the absolute path to the solution project file . This only appears to happen while 'Save as' use . If you copy the 'original' project folder to different palce , it won't write any path . I'm used to do this since early versions of VS.NET . I create my proj in the default folder , after I'm done . I copy them to my private zone besides some 'porn shots' :D

Thanks again, works like you said. That is still weird about Save As... though.
