I'm learning ASP.NET from Beginning ASP.NET 2.0 by four writters Chris 1 and 2, David, and John.
In that book they prescribe to download code for that edition from wrox's site, which I've downloaded. It's in a compressed file, which I've decompressed. Then again after decompressing, it contains lots of compressed files one for each chapter.
Then what I need to do and where to place those all files?
What I've done is I also decompressed all those files and placed them all in one folder. Is it correct method?
Like I've created one folder Beginning ASP.NET 2.0 Codes. Then inside this folder I've placed all the decompressed codes for all chapters. Is it a correct method of placing the codes?
If this is correct method then why am I getting errors in running programs?
While running the codes I'm getting this error frequently
Error 5 C:\Beginning ASP.NET Codes\Chapter03\Begin\Chapter03\WroxUnited\Default .aspx: ASP.NET runtime error: It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS. (C:\Beginning ASP.NET Codes\Chapter03\Begin\Chapter03\wroxunited\web.con fig line 41) C:\Beginning ASP.NET Codes\Chapter03\Begin\Chapter03\WroxUnited\Default .aspx 1 1 C:\...\Chapter03\
and this too
Error 2 It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS. C:\Beginning ASP.NET Codes\Chapter03\Begin\Chapter03\WroxUnited\web.con fig 41


So far I've reached at chapter 3 and this is the case.
please help.
Thanks.

Hi there,

You typically need to maintain the folder structure when you unzip. So, don't place them all in one folder, but make sure the original structure is maintained. By default, the built-in zipper of Windows maintains this structure.

The error you get is often caused by opening an incorrect folder in Visual Web Developer. Consider this structure:

C:\Downloads\BegASPNET2\Chapter1
C:\Downloads\BegASPNET2\Chapter2
C:\Downloads\BegASPNET2\Chapter3

Now, when you open up C:\Downloads\BegASPNET2\ as the root of a site in VWD and browse to http://localhost:1234/Chaper1 you get this error. Instead, open up C:\Downloads\BegASPNET2\Chapter1 and then open the site in your browser.

Hope this helps,

Imar
