XmlSchemaException in App.config using UIP Application Block

Re: XmlSchemaExcept ion in App.config using UIP Application Block

These are validation errors, are you trying to validate your file or just
parse it. If you dont need validation, turn validation off when you create
the validating reader in .NET.

That sounds useful. I've only just begun creating an application based on
UIPAB so I am just trying to build & run it with one simple View and one
simple Controller to test that I have written the config correctly.

Is it trying to validate the config file but doesn't have access to the
schema? If so, how can I prevent Visual Studio (Express) from trying to
validate the app.config?

FYI the message in the Visual Studio Immediate Window is

A first chance exception of type 'System.Xml.Sch ema.XmlSchemaEx ception'
occurred in System.Xml.dll
A first chance exception of type
'System.Configu ration.Configur ationErrorsExce ption' occurred in
System.Configur ation.dll
A first chance exception of type
'Microsoft.Appl icationBlocks.U IProcess.UIPExc eption' occurred in
Microsoft.Appli cationBlocks.UI Process.dll

and the debugging process appears to be showing me the exception is being
thrown from a statement is the UIPConfigHandle r.cs that says:

validatingReade r.Schemas.Add( XmlSchema.Read( new XmlTextReader(
streamReader ), null ) );

Thanks for your help.

Re: XmlSchemaExcept ion in App.config using UIP Application Block

If the exception is thrown from the following line that means that there was
a problem in parsing and compiling the schema that is being added.

validatingReade r.Schemas.Add( XmlSchema.Read( new XmlTextReader(
streamReader ), null ) );

Can you write out the exception message and check the error in the schema?

Thanks,
Priya

Yes I agree that is the problem.

I am using only Visual Basic 2005 Express Edition and will not provide
exception stack traces for exceptions thrown in referenced C# code, the only
exception messages are in the Immediate Window and Error List as I described
previously and repost below:

Immediate Window:
A first chance exception of type 'System.Xml.Sch ema.XmlSchemaEx ception'
occurred in System.Xml.dll
A first chance exception of type
'System.Configu ration.Configur ationErrorsExce ption' occurred in
System.Configur ation.dll
A first chance exception of type
'Microsoft.Appl icationBlocks.U IProcess.UIPExc eption' occurred in
Microsoft.Appli cationBlocks.UI Process.dll
A first chance exception of type
'Microsoft.Appl icationBlocks.U IProcess.UIPExc eption' occurred in
Microsoft.Appli cationBlocks.UI Process.dll
A first chance exception of type
'Microsoft.Appl icationBlocks.U IProcess.UIPExc eption' occurred in
Microsoft.Appli cationBlocks.UI Process.dll
....

.... ad nauseam

Error List:
Message 1 Could not find schema information for the element
'uipConfigurati on'.
Message 2 Could not find schema information for the element 'objectTypes'.
Message 3 Could not find schema information for the element 'iViewManager'.
....

.... etc. for every element and attribute in the <uipConfigurati on> section

I currently think that the process of upgrading the UIP solution to Visual
C# 2005 EE (I only have Express Editions at home) has caused a problem so
that the UIPConfigSchema .xsd is not being correctly built into the
UIProcess.dll.

This screen image may indicate that but I'm not sure:

Yahoo

http://uk.geocities.com/mjtech_uk/UIPConfigSchema_VStudio2005EE.jpg

I am currently asking a friend to try building the UIPAB on VS 2003 with
..NET 1.1 to see that solves the problem. I will post the results on this
thread but would welcome any comments/insights/suggestions in the meantime.

Thanks.

Oops, that should have said "I am using only Visual Basic 2005 Express
Edition and *it* will not provide exception stack traces for exceptions
thrown in referenced C# code"

If *it* gave me an exception report I would gladly pass it on!!! :-)

Re: XmlSchemaExcept ion in App.config using UIP Application Block

Can you try a smaller code sample by adding the UIP schema directly into a
XmlSchemaSet and check what errors/exception you get?

XmlSchemaSet schemas = new XmlSchemaSet();
schemas.Add(nul l, "UipConfigSchem a.xsd");
schemas.Compile ();

Thanks,
Priya

Sorry for the delay in replying. I did as you advised and the exception
message is below.

System.Xml.Sche ma.XmlSchemaExc eption was unhandled
Message="Wildca rd '##any' allows element 'statePersisten ceProvider', and
causes the content model to become ambiguous. A content model must be formed
such that during validation of an element information item sequence, the
particle contained directly, indirectly or implicitly therein with which to
attempt to validate each item in the sequence in turn can be uniquely
determined without examining the content or attributes of that item, and
without any information about the items in the remainder of the sequence."

I have also identified a forum thread that appears to address this problem
(explained as something to do with .NET 2.0 handling XML differently to .NET
1.1 which the UIPAB was built on) and offers a solution at

Developer technologies - Microsoft Q&A

http://forums.asp.net/713774/ShowPost.aspx

A broad category of Microsoft tools, languages, and frameworks for software development. Designed to support developers in building, debugging, and deploying applications across various platforms.

Implementing the solution prevents the original exception.

I would still welcome your comments or insights regarding this issue.

Hopefully, one day soon this *important* application block will be properly
ported to the .NET 2.0 Framework (how about it, Microsoft?!!)
