web.config

[Dan]

I am trying to add a definition for ConnString to web.config as follows
(VB.NET STD 2003)

<configuration>
<system.web>
..........
<appsettings>
<add key="ConnString" value="C:\test\test.mdb" />
</appsettings>

</system.web>
</configuration>

When I try to run it, I get "Error while trying to run project: Unable to
start debugging on web server. Server side error occurred on sending debug
HTTP request."

I have tried relocating the entry inside the <system.web> tags with the same
result.

What am I doing wrong? Thanks.

This error doesn't actually have anything to do with web.config. There are
number of reasons why this could happen, but the most common I see on my
machines is that I have betas of Web Developer Express or Visual Studio.NEt
2005 on the machine. These cause the app to run as a .NET 2.0 app. *IF* this
is the case, download Denis Bauer's excellent ASP.NET version switcher from
http://www.denisbauer.com/NETTools/ASPNETVersionSwitcher.aspx&e=9901. Then
run it, point it at your application and switch it back into .NET 1.1
instead of .NET 2.

If you aren't use a .NET 2.0 beta anywhere on the machine take a look at
http://support.microsoft.com/default.aspx?scid=kb;en-us;306172. This
describes common error messages and how to resolve them with .NET.

Finally, the settings you posted for your web.config indicate that you want
your application to access a local file at runtime. SInce this is a web
application, make sure that the web application user has access rights to
that file or you will find that you will next get a security violation error
thrown when you do resolve the problem.

Hope that helps,

I don't have NET 2 on the machine. I haven't used the "file" attribute in
the appsettings code so why would it think that I am referring to an
external file? The error comes up before the appsetting is accessed by vb
code. when I try to debug start---There are no compile errors.

The KB article says that this error arises from a syntax error in the
web.config file. If I remove the three lines from the web.config file, the
problem goes away.

It doesn't matter what I use as the key name or the value. If those lines
are present the rror is tripped.

Hello Dan,

You definitely provided more information in that response. You also appear
to be a bit unhappy with Pete's response. He's only trying to help.

First off, the App Settings section appears under the configuration tags,
not within the system.web child:

<configuration>
<system.web>
...
</system.web>
<appSettings>
<add key="somekey" value="somevalue" />
</appSettings>
</configuration>

Next, XML is case sensitive. It is not an <appsettings> section. it is an
<appSettings> section.

This is probably your problem.

For further info, this article is often useful:
http://samples.gotdotnet.com/quickstart/aspplus/doc/configretrieve.aspx

Also, the reason that Pete assumed that you are accessing a file is because
the CONTENT of the config app setting that you posted was a filename. He
was hoping to help you out of the next issue you may face: the fact that
ASP.NET applications do not normally have access to file system resources.

I hope this helps,

Sorry and thanks....

Sorry to say, that solution resulted in the same error message. Here is the
code I have copies from web.config

..............
</system.web>


<appSettings>

<addkey key="connstr" value="something" />

</appSettings>


</configuration>

Any other clues would be appreciated.

Thanks, Dan

Hi Dan,

The schema for config files is set by .Net. The tags are very specific.

The tag you need is not "addkey" but rather "add"
so <addkey key="connstr" value="something" />
becomes <add key="connstr" value="something" />

HTH
