If there were no namespaces then you could not mix different XML 
vocabularies as you could not distinguish for instance the XHTML 'table' 
elment from a 'table' element in another vocabulary. Using namespaces 
the complete name of the XHTML 'table' element is 
{http://www.w3.org/1999/xhtml}table where the URL 
'http://www.w3.org/1999/xhtml' provides the globally unique context for 
the local name 'table'. And any {http://example.com/foo}table is 
different from that.

ADFS basics
Hey all, I'm using (trying) to use ADFS to logon to my SAML 2.0 parter. In essence I would like to use AD as my source of truth. Unfortunately, I'm having some issues with my logoff and trying to troubleshoot. One super basic question, the directory /adfs/ls which is used as my logoff URL (and logon URL) has a default document setup as default.aspx which does not exist. Question 1: How does pointing to the adfs/ls directory alert ADFS to which action I'd like to perform? It obviously works but I'm not sure how ADFS know whether to pop a logon screen or go...

Disdplaying resulting XML Response as Raw XML on Web Page
This may be trivial. It was back when I did HTTP POST with XML Docs. Now on ASL.Net I'm using XML proxy classes and everything I've tried tries to act on the XML. I have a test ASPX page that I use to test web service. When response is returned I want to open a new window and disdplay result as XML. I don't want tags removed. I don't have any XLST. I just want to popup with raw XML tags and all. I don't mind invoking anoither ASPX page to display the XML. I'm guessing the is very easy, or should be. doug wrote: > This may be trivial.

How to pass xml inside xml to an xslt
Hi I have an xslt. The input to the xslt is a dataset. In that dataset, in one of the datatables' column I am stroring xml data using XmlDocument. Now, when I transform this xslt in c# I get the following error: "Unexpected XML declaration. The XML declaration must be the first node in the document, and no white space characters are allowed to appear before it." Is there a workaround to this problem?

Sorry
Hi guys, apologies for such a basic question. In my defence I'm not really a c++ programmer, and when I have dabbled, I've used MFC. I've got a call to an external DLL I'm using LoadLibrary to get. I've declared the call as : lpFUNCTION MyFunc(CString p1, CString p2, short* retVal, CString* retText) if I call it : short retVal; CString retText; iRet = MyFunc ("123456", "12345678", &retVal, &retText); - it works fine. Unfortunately this DLL is being called from a non-MFC app. So I;ve tried : lpFUNCTION MyFunc(char[] p1, char p2, short* ...

Is there XML support in VS.Net 2005?
For those of you beta testing VS.Net 2005, have they added any XML classes to MFC? Have there been any other "big" enhancements to MFC? Yeah, yeah... some people say MFC is dead, but it is still *THE* easiest/best way to develop a real world desktop application. I dont exactly know what enhancements would be there in MFC regarding XML but I wouldnt be surprised if this is not addressed. XML support is far better in .Net than MFC and you can use .Net with MFC as well. Although it may not be something you like because you will create .Net run time dependency. -- Ajay Kalra [MVP...

xml document
hi, I have a huge xmldocument that represent data from a table. How can I break this down into multiple xmldocuments, say of a certain number of records each? The least memory intensive solution would be to read over the source document with an XmlTextReader and switch to a different output ( presumably a file ) every so often. <pseudoCode> XmlTextReader reader = new XmlTextReader( ... ); XmlWriter writer = new XmlTextWriter( GetNextFilename() ) int pageSize = 100; // chunk every 100 rows int currentRow = 0; // Init the writer writer.WriteStartElement( "myRoot" ); // be...

basic System Policy question
If I understand this correctly System Policies are really only useful in cases with multiple information stores (Enterprise version only) so that settings can be set for all of them in one central place. Can settings set in a System Policy be overridden at a lower level like an individual information store itself, or an individual user account? Or do System Policies rule no matter what, no overrides? System Policies are Enforced (No-Override) at Store level or Server level. However, individual user account settings can override Store level setting, including System Policies settings. ...

Excel 2007, Basic, Square-1 Opening Question
Clicking on an xls or an xlsx file opens Excel 2007; however, the file itself does not load/open (no blank sheet either). Only way is to drag the file from its directory. What have I done wrong? Tks! Wayne Try minimizing and then maximizing Excel to see if that makes the file appear. If it does, I'll build a small routine that does that automatically when a file is opened. This appears to be a very frequent problem for some Excel 2007 users. Bob Flanagan <wgd.roaming@verizon.net> wrote in message news:9jg3b49oe5t308vjcngefg41f5htajrm2r@4ax.com... > Clicking on an ...

Easy XML ?

Parsing XML over TCP/IP
Sorry if this has been posted before... I am receiving XML messages over a TCP client. Messages vary in size and sometimes can arrive in groups. Thus, I am not guaranteed to receive a full message in a single read from my socket. I am loading each message into an XmlDocument after it arrives. I need a way to make sure I have a complete XML message before I load it into an XmlDocument or it will throw an exception. I am currently finding complete messages by turning each read into a string and manually look for closing tags. Surely there is an easier way to accomplish this, perhaps with ...
