Writing XML Attributes With XMLWriter?
Jan 18, 2010I'm trying to generate the following header for an XML document using VB.NET and the XMLwriter but have been unable to generate the "xmlns:xsi" and "xsi:noNamespaceSchemaLocation" attributes. It seems I'm missing something, I was hoping someone can help with the XMLwriting calls and maybe even explain a little bit of what those attributes are doing.
Required Output:
<?xml version="1.0" encoding="utf-8" ?>
<orgStructures startDate="2007-09-24" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="<REPORTING-INSTALLDIR>sitewebappsflexnetschema[code].....
The above code isn't producing what I need. Other code I've tried, like passing "xmlns:xsi" as the name of the attribute produces error.
Xml - XmlWriter Not Creating New Element?
Oct 23, 2009I'm writing out an XML file using VB.net. When I try to create another element to be written past the first, it errors out saying:
"Token StartElement in state EndRootElement would result in an invalid XML document. Make sure that the ConformanceLevel setting is set to ConformanceLevel.Fragment or ConformanceLevel.Auto if you want to write an XML fragment."
I'm not sure why it is doing this considering that the previous element has been closed. I tried to look for a writer.WriteEndRootElement, but I didn't see any in there. Any suggestions to get it to work?

XMLWriter: How To Change What's In The Header
Jun 22, 2009I have a requirement to make an XML file - and the partner is rather sticky about the header. Apparently, the header must be exactly this:[code...]
The hacker in me wants to stop using XMLWriter to make the file so that I have more control over the header; "no problem, I'll just write a loop that makes its own XML tags as a StreamWriter or something, forget this XMLWriter object..." but I must admit that XMLWriter has been rather elegant to use so far; surely there must be something where I can change the XMLWriterSettings object to say "stop putting your custom properties in to the XML header please", right?
[code...]
Works perfectly; but I can't find a way to control the header. I can find a way to remove it entirely of course but that's not what we want to do.
Output XML To ASP.NET TextBox With Formatting Using XmlWriter?
Feb 28, 2011I am building an XML string programatically using the XmlWriter ...
sb = New StringBuilder()
writer = XmlWriter.Create(sb)
writer.WriteStartDocument()
[Code]......
I want to be able to output the XML to a TextBox control on a ASP.NET webform. When I do output the XML I don't get any line breaks or indentation in the XML. The XmlWriter does not seem to have any properties to set formatting. Is there anyway to retain formatting and indentation?
Writing Output With Stringwriter And Xmlwriter

Nov 4, 2011I have the following code. I am loading the xml file, it's fine. When get into my loop and try to read the line I get unhadled exception and the following error
'Part ID="1"/SalesPrices/OrderPrice/GrosscostsAPiece' has an invalid token.
I have discovered that the reader is not liking the Part ID="1" part. How to overcome this problem considering the xml will always have that element as it is. Need to extract the value in the GrosscostsAPiece element.

Use An XPathNavigator Select To Get A Node Iterator - Invalid Token Error

Add DB Query To DGV Throws Exception When Adding Row
Apr 24, 2011I debated whether or not to ask in the database section, but decided this was probably more of a VB question, than DB.I'm performing a query on my database and add its value to a DGV. At the moment, I'm just running tests to make sure the base example works so I can expand on it for more advanced tests.[code]It doesn't matter how I add the row, just adding it causes the error. And yes, the AllowUsersToAddRows property of the DGV is set to True, which wouldn't cause this problem anyway, but I decided to be extra careful.

View 1 RepliesVS 2008 VB / Excel Automation - Throws An Exception On 'PC#2
Nov 3, 2009VB2008 (in VisualStudio) and automation of tasks in Excel. My work env.: PC#1 - WinXP Sp3 with VisualStudio & Office O27k (all US-EN) installed, PC#2 - when I am not at home I use an Laptop with WinXP + O27k (DE) and VisualStudio(US-EN), but the mix of language does not seem to be a problem - at least until now!
In one 'TestBench' appl. I have the following line of: oWB.Names.Add("DR_AppData2", RefersToR1C1:="=OFFSET(AppData!R3C1,0,0,(COUNTA(AppData!C1)-2),1)")
Where 'oWB' is a WorkBook Object and 'Names' refers to named regions in an Excel worksheet. I am adding a new 'Region': DR_AppData2 and assigning a dynamic number of rows.
The above line works perfectly well on 'PC#1' but throws an exception on 'PC#2' and this has really irritated me, and I find no reason for this behaviour! The Project environment and included references / resources are truly identical, because I copy the project data from one to the other. The only real difference is in the object library reference, on 'PC#1' Excel.exe is in English, and on 'PC#2' is in German. Having said that I have also altered the value assigned in : "RefersToR1C1:=" to the equivalent in German, but the error thrown is the same.
I have attached :
