Hi all,
I am developing an application in VB.Net, which uses XML file to feed configuration information. Application will need different configuration information during run time which needs to be fetched from XML file. Please let me know to achieve this task what will be the best approach:
Deserialization: Deserialize entire XML file into an object, and keep this object in memory during the entire life of application. Get the configuration information form this object property.
Using XPath query: as and when the configuration information is required by the application, it sends a query to XML file to fetch the required information.
Experts, please comment on this.
Thank you,
Regards, Krishnaraj

Support for using XML files for application settings is provided in the .NET BCL. You have not stated what type of application you have but this might help[^]

hi i used to use c# to display my uploaded picture
if (openFileDialog_select_picture.ShowDialog() == DialogResult.OK)<br />
{<br />
pictureBox_contact.Image = Image.FromFile(openFileDialog_select_picture.FileName);<br />
<br />
<br />
pictureBox_contact.SizeMode = PictureBoxSizeMode.CenterImage;<br />
pictureBox_contact.BorderStyle = BorderStyle.Fixed3D;<br />
<br />
}
but how do i do that in wpf.. ?
i cant do pictureBox.Image or .SizeMode....

You will probably have better luck asking this in the C# forum. Even though WPF uses an XML dialect (XAML) this really isn't an XML question per se.
WPF doesn't have a PictureBox control, instead you need to use the Image control and set the Source property. Take a look at this blog post[^] for more information.

How to get the value of "hw" and "pos", xml file:
<?xml version="1.0" ?>
<Root>
<w c5="NN1" hw="factsheet" pos="SUBST">FACTSHEET </w>
<w c5="DTQ" hw="what" pos="PRON">WHAT </w>
<w c5="VBZ" hw="be" pos="VERB">IS </w>
<w c5="NN1" hw="aids" pos="SUBST">AIDS</w>
<w c5="NN1" hw="aids" pos="SUBST">AIDS </w>
<w c5="VVN-AJ0" hw="acquire" pos="VERB">Acquired </w>
</Root>
Here is a piece of code:
MSXML2::IXMLDOMDocumentPtr pDoc;
HRESULT hr;
hr = pDoc.CreateInstance(__uuidof(MSXML2::DOMDocument40));
if (FAILED(hr)) {
MessageBox("err");
return;
}
pDoc->load("d:\\a01.xml");
MSXML2::IXMLDOMNodeListPtr pNodeList;
MSXML2::IXMLDOMNode *DOMNode=NULL;
CString strContest;
try {
pNodeList=pDoc->getElementsByTagName("w");
int j=pNodeList->length;
for(int i=0;i<pNodeList->length;++i) {
pNodeList->get_item(i,&DOMNode);
strContest=(LPCSTR)DOMNode->Gettext();
MessageBox(strContest);
}
} catch(_com_error &err) {
CString strErr=(LPCTSTR)err.Description();
MessageBox(strErr);
}

You have to use the attributes property (i.e the get_attributes method) and then the getNamedItem on the returned NodeMap, check out the C++ sample of the getNamedItem documentation:
http://msdn2.microsoft.com/en-us/library/ms767592.aspx[^]
it does almost exactly what you need (it retrieves an attribute of the documentElement, but the same applies to a standard node).
Please note that you can also do a more intensive use of the smart pointers to make code more concise.

A little more information would be good to get an answer to this, such as what progamming language? For .NET, you can use the XmlDocument class from the System.Xml namespace.

I have a newbie question...
I would like to save the format of a text, i thought writing another file to keep all this info but I thought i could do it with a xml file only, but i don't know how to use XML.
How could i do that every time i save a file i can save its format in the xml file?
thanks all

XML is a structured text format. Your text data needs to have some structure to it, preferably hierarchical, for you to consider storing it as XML. Otherwise you'd be better off just storing it in a text file.

There's plenty of resources on the web for learning XML. Alternatively, buy a book.

I need to create a generic XSLT to extract the third level elements of an XML file without having to specify the element names in the XPath.
The XML file looks like that
<?xml version="1.0" encoding="ISO-8859-1"?>
<catalog>
<cd>
<title>Empire Burlesque</title>
<artist>Bob Dylan</artist>
<country>USA</country>
<company>Columbia</company>
<price>10.90</price>
<year>1985</year>
</cd>
.
.
.
</catalog>
I need to put the Elements names like title, artist, etc. in a table as header and the element text Empire Burlesque, Bob Dylan in a table cell.
Can someone assist me with this please it seems I cannot get it right myself. Here's what I am trying but doesn't work
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<html>
<body>
<!-- The heading -->
<div>
Results
</div>
<br/>
<!-- Define the table itself -->
<table width="100%" border="1">
<xsl:apply-templates/>
</table>
</body>
</html>
</xsl:template>
<xsl:template match="*">
<xsl:for-each select="*">
<xsl:sort select="*"/>
<tr>
<td><xsl:value-of select="*"/></td>
</tr>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
Thanks

Thanks for that it works. However when I am trying to add <xsl:sort select="*"/> after the <xsl:for-each select="*"> to sort by the first item doesn't work. Am I missing something?
Thanks

Hi all,
My question is very simple;
I have two arrays :
double[] arr1 = new double[] {1,2,3};
double[] arr2 = new double[] {10,20,30};
I want to store to and than read these arrays back from an XML file.
Could someone please send a small piece of code written in C#.
Thanks.

That's not how things work here. We don't do your work for you.
Anyway, you need to be more specific about what you want to do. How should your XML be structured?
I suggest that you do some more research, attempt to solve the problem yourself and post again if you encounter any further difficulties.
I've just noticed that you posted the same message[^] 2 days ago and were given some help. Why have you posted it again? Why have you failed to act upon the advice you had previously received?

Hi,
Regarding the help posted 2 days ago, The solution offered in that transaction was not the way that i need, because I used that method before.
As for your questions;
<br />
<code><br />
<duttest><br />
<test1><br />
<arr1>500,525,550,575,600,17425,18000,</arr1><br />
<arr2>4.08,6.96,8.91,7.79,7.72,2.34,4.56</arr2><br />
</test1><br />
</duttest>
My xml document is given above. I write my arrays comma delimited to xml file but when the array size is large,say 1000000, it becomes cumbersome to write and read back. Because I have to use text processing. So, to overcome such text processing;
Is there a way to store to and than read these arrays back from an XML file.

When I use the VS2005 xsd gui (which I love) to build a schema what's the simplest way to generate a valid, unpopulated xml file? Do I have to write some C# code or is there a menu-driven tool that I'm missing.
Thanks.

So your xslt is generating wordml? If yes then....
Ron.S wrote: but xsl is creating table one below the other .. Any hint what setting i would have missed ??
means you are not correctly generating wordml to it's specification. You need to find out the correct wordml you need and then change your xslt to generate it, yes?
