Hello again... 
I really appreciate the help you folks are giving me.
I have an XmlElement from a validated XmlDocument. I can't find a way to retrieve the element's expected attributes from its SchemaInfo property.
I was hoping this property would tell me all about how this element is described in the schema (i.e. what child elements are valid on it, what attributes are valid on it, etc.).
Am I barking up the wrong tree? I simply need a list of ALL valid attributes on the element.
BTW, XmlSchemaValidator looked promising, but it always returns null from the GetExpectedAttributes method when the context is the element that was validated. It retrieves the attributes for any of the validated element's CHILD ELEMENTS but can't seem to retrive them for the validated element...
Thoughts?
Thanks so much!
Ian

Never done this before, but basing on the docs I think the following may work:
XmlSchemaType xmlSchemaType = xmlElement.SchemaInfo.SchemaType;
if (xmlSchemaType is XmlSchemaSimpleType)
{
}
else if (xmlSchemaType is XmlSchemaComplexType)
{
XmlSchemaObjectCollection attributes = ((XmlSchemaComplexType)xmlSchemaType).Attributes;
}

Thanks for the reply. I actually figured out how to get the information from the XmlSchemaValidator.GetExpectedAttributes method.

Hi,
Well i'd like the pages in my site to appear differently (such as background color, text size, font etc) based on if the user click on a certain button from the home page. Now the pages are the same as when the user doesn't click on the button (use customized site) and therefore what I'm thinking is to create new style sheets (in addition to the ones that are currently being used by the pages) and then add their references to the aspx pages also (since we could have multiple external style sheets in any particular aspx page). What do you guys think about this approach?? or if there's a better design then this???
Secondly if I go with this approach, how do I make the subsequent pages (after the user has clicked on Customize my site button) use the newly created styles sheets with my new properties?
Any suggestions would be appreciated!
Thanks

Derive all pages from a common base. Set the style sheet file in a variable, which stores it in the session. Make the base class set the CSS file from that property.

Hi all,
Hoping someone can point me in the right direction here. I'm writing a VB.Net 2.0 WinForms admin app to allow users to do maintenance on an Oracle database behind another very large app.
To keep the size of the admin app down and to avoid a maintenance nightmare when the tables (about 70 of them) change I am trying to write it so it's totally automated. I already have code to read the schema of each table to get the columns and then I have a form that adds an appropriate custom control for each type of table column. This works very well but I need it to be advanced enough to hide some columns, make sure others are entered, validate some others, etc, etc.
So my idea is to have an XML file (see below) containing the tables and columns which can be maintained and when the app starts it would read the file and load the data into .Net classes which correspond to the XML (see class definitions below). I can then use these table and column classes to apply custom behaviour to the custom edit form I already have.
So, looking at the XML and class definitions (both kept VERY simple for illustration purposes) can anyone tell me how best to go about this? How could I best read the XML file in and convert it to the classes I've defined?
TIA for any help... I know how to write using lots of fairly manual code but am hoping there is a smarter & quicker way to to do this.
Mike.

Sounds like the XmlSerializer is what you're looking for.

Thanks - what I did in the end was read the file into an XMLDataDocument object instead of a class structure as it means I can use XPath/XQuery and also have the power of the DatatSet object as well. Once I created the schema file (by loading the XML file into VS2005 and choosing Create Schema from the XML menu) the code was simply as follows:
Public Sub LoadXMLConfig()<br />
<br />
'Read the XML configuration file<br />
dataDoc = New XmlDataDocument()<br />
dataDoc.DataSet.ReadXml(My.Settings.XMLConfigFile)<br />
<br />
End Sub
Just thought I'd post this in case anyone else is wanting to do this sort of thing and comes across this thread.

In Word2007 the document is saved as *.docx, which unzips to reveal a group of XML files, including fontTable.xml. If the fonts were embedded that table will include a fontkey for each embedded font, something like:
4FC99FC9-34EB-48D7-B509-17C906D3B8E1
When the docx file is unzipped it includes also a font-like file for each embedded font, with an extension .odttf . This differs from the usual ttf file only in the first 32 bytes, and it is obvious that the application of the key to these 32 bytes will transform it so as to give a valid ttf font file. For that it is necessary to read the key in reverse direction, E1B8 D306... Some times it is only a matter of getting the difference between these words and the corresponding words in the odttf file. However I cannot see the full solution.
Does anyone know how ? I don't see why MS would want to conceal it.

Hi all.
In my application I am downloading an XML file from the server.
But I don’t want the user to be able to read its contents.
So my question is….
How can I encrypt an XML file and decrypt it while reading its contents through code?
OR
Can I hide some of the tags from an XML file so that user will not see those when he opens that XML?
Thanks

No

What server? Web Server? If Web Server the most common way is to use SSL. Otherwise look at the Crypto API.

Make an Installer Project

I was asking how can we develop it and not by Installer Project! Whether it is using XSLT or C#.Which is the preferred and a better way to develop?

I am not familiar with the word "upgradation". If you don't want an installer for updating the components of the application, what do you want?

whenever a software is upgraded to another version, the xml files should also be upgraded to that version.
So what i meant was that all the xml files should be upgraded to another version with any changes to its attributes or element values at the time of s/w upgradation.

What mechanism are you using to upgrade the software if not an installer?

I'm assuming zxc89 means that when the app starts on the user's machine it would contact a web server to look for a newer version of the app then download the updated version including the updated XML files... this is what I need to do in my app as well so I'd also like to know what the options are for doing this.
If this is not what you mean zxc89 then you need to tell us what you mean!

Far too many to list. With each one twisting and turning the issues involved into a jigsaw puzzle. Most likely the simplest and safest (robust) approach would be to use Bits. You can get started by reading this article[^].

Hello,
What is the best way to get an XmlDocument from an XmlNode?
I have a document that I run an XPath query against that returns an XmlNode. I want to create an XmlDocument from the XmlNode (using the XmlNode as the root node of my new document).
I could create a new XmlDocument, then parse the XmlNode adding each node to the document, but I want to know if there's a better way to do this before I proceed.
It seems like this would be a common problem.
Any suggestions?
Thanks!
Ian

Maybe you can use the XmlDocument.LoadXml method and pass in the result of XmlNode.OuterXml.

In other words, how to use XML from C#. Take a look at System.Xml namespace, and come back with more specific question.
