This is the second time I am asking this question in this newsgroup
since I haven't got a solution or response from anyone in my previous
post & I need to resolve this issue desperately. Sorry for the double
post but I just didn't have any other option other than re-posting the
same question in this newsgroup.

Consider the following code in a VB class file:

Namespace LoginUserFetchDB
Public Class ZForZebra : Inherits SoapHeader
Public UserName As String
Public Password As String
End Class

Public Class GetDBRecords : Inherits WebService
Private sqlCmd As SqlCommand
Private sqlConn As SqlConnection
Public sHeader As ZForZebra
...............
...............
End Class
End Namespace

Using VBC. I compiled the above in LoginUserFetchDB.dll which resides
in the folder C:\inetpub\wwwroot\ASPX\bin

Have a look at the line

Public sHeader As ZForZebra

Though the above code & the ASPX page which uses the above DLL works
without any problems, what I find is Visual Web Developer 2005 Express
Edition underlines the word 'ZForZebra' saying that

'ZForZebra' is ambiguous in the namespace 'LoginUserFetchDB'.

That's the reason why I used such an absurd class name 'ZForZebra'
since I am pretty sure that the .NET Framework won't be having any such
class name. Neither have I used such a class name in any of my class
files (or any other .NET related files) any time. I also tried using

Public sHeader As LoginUserFetchDB.ZForZebra

but that didn't make any difference.

After a lot of research, using the Object Browser, I concluded that
LoginUserFetchDB.dll not only exists in the above-mentioned bin
directory, it also exists at 2 more places:

C:\WINNT\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET
Files\aspx\98099ba2\_shadow\695771b\bin\2\

&

C:\WINNT\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET
Files\aspx\443e485a\_shadow\ff53954a\bin\2\

It was only when I deleted LoginUserFetchDB.dll from the above 2
folders did VWD 2005 stop highlighting this ambiguous name error.

Though I don't think that's could be the reason why VWD is highlighting
that error since in other VB class files using similar code, VWD
doesn't highlight the error. So how do I avoid the ambiguous name error
in VWD?

I don't understand what's causing the ambiguous error since I am more
than 100% sure that I have not used a class with the name 'ZForZebra'
anytime anywhere!

Someone please help me this time atleast.

I really doubt that this question is such a difficult question to
answer for ASP.NET MVPs & gurus.

Is it an actual error (i.e., is it compiling) or is it just VWD reporting an
error in the editor?

If it's still compiling and working fine, I woudlnt' worry about it. I've
seen VS.NET 2005 report bogus errors in the past (although, a restart
generally solves the problem).

If it is a real issue, can you provide me with a zip of the project?

Only VWD reports this error; the class file compiles successfully & the
ASPX page using the DLL works fine in IE as well without any errors.

I agree with you that I shouldn't be worrying too much on it but I
would like to know WHY is VWD generating the error when I am more than
100000% sure that never ever in my life have I named a class
'ZForZebra' in any of the ASP.NET related files residing in my Intranet
server! Restarting doesn't resolve the issue.

Or, maybe it's a bug in VWD 2005 otherwise I don't find any reason for
VWD to report the error!.

the reason it is "ambiguous" is likely because the class exists in two locations :

1. in the app_code folder where it is developed and
2. in the /bin folder where it is compiled.

you can only use one or the other.

Delete the /bin folder after confirming it will compile and continue your development work. For production only transfer the DLL to
the production server, not the app_code folder contents.

Jon, all my ASPX pages reside in C:\Inetpub\wwwroot\ASPX directory & I
don't find any folder named 'App_Code' within the ASPX folder though
numerous 'App_Code' folders exist as sub-folders within the C:\Program
Files\Microsoft.NET & C:\WINNT\Microsoft.NET folders but none of them
have any DLL named 'LoginUserFetchDB.dll'.

The ASPX folder has a sub-folder named 'App_Data' which has 2
database-related files - ASPNETDB.mdf & ASPNETDB_Log.ldf.

Any other ideas? Should I create a folder named 'App_Code' in the ASPX
folder, copy-paste all DLLs from the 'bin' folder (existing in
C:\Inetpub\wwwroot\ASPX) to the 'App_Code' folder (& then delete the
'bin' folder) or re-compile all VB class files into DLLs (using VBC) &
save them in the 'App_Code' folder? Will that resolve the issue?

sounds like the problem is you don't have a clean website defined in IIS.
You seem to have everything in the wwwroot folder.

--Create a website in IIS and then
--create the correct folder structure in that website
--put your files in the correct folders

Wow....saving any VB class file in the 'App_Code' directory doesn't
necessitate the developer to compile the corresponding assembly (DLL)
using VBC in the 'bin' directory.....that's great!! But are there any
performance benefits of one over the other?

Thanks for the link, Jon. The article indeed turned out to be pretty
helpful though I haven't yet got the time to go through the entire
article......will go through the entire article in a day or two....:)

It's the new default project model in 2.0. They are compiled JIT. It allows
for files to be swaped on the fly without having to recompile. Performance
shouldn't be an issue.
