I have an xsd (One of the elements in it is defined by an xs:enumeration). This xsd will change from time to time. So, my code should work even when the xsd changes.

My Tasks (on a winform):
1. Build a dataset from xsd (easily achieved ds.ReadXmlSchema("sample.xsd"))
2. Bind a datagrid to this dataset (dataGrid1.DataSource = ds.Tables[0])
3. Display a combobox in the column (which defined by an enum in the xsd) and display the enum values in the combo box(Problem)

I am looping through the columns of the datatable and trying to figure out if it was defined by an xs:enumeration in the xsd. During runtime, I can see that ds.Tables[0].Columns[2].SimpleType.enumeration contains the list of enumerator values. But, I am unable to figure out how to get to it during design time.

It would really if someone could tell me how to determine if a datacolumn is supposed to be taking only enumeration values provided in the xsd, and how to get access to these values so I can bind them to a combobox

I really appreciate the time you took to reply to this post!

Extract from a Sample XSD defining three columns:
<my:element name="ID" type="xs:decimal" minOccurs="0"/>
<my:element name="StartDate" type="xs:date" default="1990-01-01" minOccurs="0"/>
<my:element name="Employee">
<my:simpleType id="EmployeeName">
<my:restriction base="xs:string">
<my:enumeration value="Cinderella"/>
<my:enumeration value="Rupenzel"/>
<my:enumeration value="Black Beauty"/>
</my:restriction>
</my:simpleType>
</my:element>

XML forms

My company uses XML received by email all the time to receive information from different sources everyday. I'm looking to improve the speed a little bit more as email has normally a delay. What's the best way to receive those forms? I created a webservice, however some of our providers do not want to spend the time building a solution. I would like something I can provide to them in order to received those forms.

Any ideas?

Hard to say what is "best" when you don't have all the information. Here is a wild guess. If you have a Web Server you could supply a web page that allows the user to Upload the file to your server.

No doubt. However I was guessing that his concern about the time lag was due in large part to the SMTP lag that sometimes occurs. Biztalk would have no effect on that.

xs:time limit?

Hello,

I tried searching the net but I couldn't find this info... Does an xs:time attribute have an upper limit? Like, maybe the maximum value is 23:59? or can it contain time values which are greater than 1000:00 ? This is for an attribute that is more of a duration time attribute than a date time attribute and I'm wondering whether I should use xs:time or xs:string instead.

Thanks,
~Rafferty

perhaps you could use xs:long and have the value be the duration in milliseconds?

I just found out that there's an xs:duration datatype. That'll work very well.

but just out of curiousity, does xs:time handle time values that is more than 24 hrs?

Thanks,

No. from the W3C[^]

[Definition:] '00:00:00', up to but not including '24:00:00' 
(which is identical with '00:00:00' of the next day).

How to re-organized XML file and call XML file from my software

bella_1104198810-May-06 22:57

Hello, everybody. Sorry to disturb you all.
Currently, I have a speech recording and playback software developed by Microsoft Visual C++ 6.0. The software is used to train children with speech problem and scores will be calculated and showed at the end of each practice session. The software is able to record and playback real-time.

Children use this software at home and save their practice records in a single floppy disk. Then, children will bring the floppy disk with practice records inside when they return to our centre.

I have two problems with the xml programming part. My software automatically created history file (in XML format) to display the scores of the children’s practices. The history file (in XML format) is saved by the children in floppy disk when they return to our centre.
But, the data or information in the XML is in a mess where all data are put together. Do you mind to tell me what should I do to create more organized XML format? The therapist needs to scroll in order to read the scores. I have the program codes of XML in four of my cpp files.

The second question is how to call or open XML file (the history file) from my software?
My codes are as below. After I execute the program, it is error free and the File Open dialog box is popped up but no XML file came out after I select the desired XML file. My codes are as below:

void CSpeechDlg::OnScore() <br />
{<br />
	// TODO: Add your command handler code here<br />
CFileDialog openfile(TRUE,NULL,NULL,OFN_OVERWRITEPROMPT,"XML File (*.xml)|*.xml|");<br />
	if (openfile.DoModal()==IDOK)<br />
	{<br />
		CString cs=openfile.GetFileName();<br />
		char* filename=new char[cs.GetLength()+1];<br />
		strcpy(filename,cs);<br />
	}<br />
	<br />
}<br />

I promise I wont disturb you a lot, I promise I will do my best. Can you please help me?
I am totally new to this as the software is written by one of my previous friend who worked together with me in a voluntary speech rehabilitation centre. We need this software to train children in the centre. I work part time there.

Hope you can give me some guidances on how to do it. I promise I can learn as independent as possible but I really need your guidance at this very beginning, please.
Please, I really appreciate all your help.

From VC 6 you will want to use an XML library (parser). Probably the most widely used in VC 6 applications will be the MSXML library that is located in msxml(n).dll where "(n)" is the installed version on a given computer.

YOu can find many articles on using MSXML from VC++ on MSDN, CodeProject and many other sources.

Good luck.

I am kinda new to using regular expressions, but I need to create a new one to use in an XML schema for login name validation and I can't get this to work.

I need a regular expression that will allow string values of A-Z ,a-z, numeric (0-9), "@", "-", "_", ".", and "'" as login name allowable characters. Any help or direction would be appreciated.

Thanks

xslt code to save in csv format

Hi guys,
I want to write a xslt code that creates a csv file (with all output in it) & saves to a particular folder without any manual intervention.
I've been looking xslt function definitions for file processing but with no success.
Could anyone throw me the snippet please
Thanks

Mohan

There are no XSLT functions for file processing - XSLT is not a system programming language. You can only save the result (using any other -system-level- language) coming from your XSLT processor.

I am attempting to extract some data from the xml below with the following code:

XPathDocument xmlDoc = new XPathDocument(URL that I supply);
XPathNavigator nav = xmlDoc.CreateNavigator();
nav.Select("/ISBNdb/BookList/BookData/AuthorsText");
Console.WriteLine(nav.Value);

The problem is the value returned is all of the elements concatenated together:

You should use the XPathNodeIterator which is returned from the Select method, not the Value of the navigator.

private void Form1_Load(object sender, System.EventArgs e)
{
	XPathDocument xmlDoc = new XPathDocument("..\\..\\data.xml");
	XPathNavigator nav = xmlDoc.CreateNavigator();
	XPathNodeIterator iter = nav.Select("/ISBNdb/BookList/BookData/AuthorsText");
	while( iter.MoveNext() )
		Console.WriteLine(iter.Current.Value);			
}
