Hi ,
I am validating an xml that express an an invoice document.
this documnt always have header and lines.but somtimes (not always) have serial numbers.
When I am validating the xml against the shcema I want the validator to ignore if the serial number element does not exist.
I can't change and I don't want to change the schema Since i am getting it from a third party software.
What can I do to ignore it?
see, my code and a part of the schema below:
I am using this code to validate xml file to xsd file:
private void ValidateSchema(string filePath)
{
XmlReaderSettings settings;
XmlDocument doc;
XmlReader reader = null;
try
{ settings = new XmlReaderSettings();
settings.Schemas.Add(null, m_sSchemaPath);
settings.ValidationEventHandler += new ValidationEventHandler(settings_ValidationEventHandler);
settings.ValidationType = ValidationType.Schema;
doc = new XmlDocument();
reader = XmlReader.Create(filePath, settings);
doc.Load(reader);
doc.Validate(settings_ValidationEventHandler); }
finally
{
reader.Close();
}
}
this is part of the the XSD(a few complex type elements):
<element name="Documents">
<element name="Documents_LINES">
<element name="SERIAL">
thanks in advanced,
A Y

Hi to all,
I am writting a C# Windows Application in which it uses XML to store & retrieve Student Data (like Name, Addres, DOB, Educational Details, Economical Conditions, etc).
To store & retrieve data from XML, I am using XmlSerializer class.
But some student data are in form of paragraph (like Educational Details, Economical Conditions, ..). How to store & retrieve that data using same XmlSerializer class?
Thanks & Regards,
Aniket A. Salunkhe

It's just XML. You can put carriage returns inside the data.

Thanks for reply.
Where & How to put carriage return?
If I am getting a value for an attribute as "Test Line1\nTest Line 2\nTest Line3" from XML; then
do u mean to convert it to "Test Line1\r\nTest Line 2\r\nTest Line3".
Thanks & Regards,

Following is working properly, without taking care of carriage return.
Here I am using XmlTextReader & XmlTextWriter instead of FileStream.
//XML to .NET Object (Reading XML)
using (XmlTextReader xtr = new XmlTextReader(new StreamReader(sXmlPath)))
{
XmlSerializer xserObject = new XmlSerializer(typeof(Child));
objChild = (Child)xserObject.Deserialize(xtr);
//objChild = xserObject.Deserialize(xtr) as Child;
xtr.Close();
}
//.NET Object to XML (Writting XML)
using (XmlTextWriter xtw = new XmlTextWriter(new StreamWriter(sXmlPath)))
{
XmlSerializer xserObject = new XmlSerializer(typeof(Child));
xserObject.Serialize(xtw, objChild);
xtw.Flush();
xtw.Close();
}
Once again thanks for your support.

Datagridview does not provide any fuctionality to search on its own.

What have you tried so far?
Infact, its better to search the DataSource which is bound to the datagridview.
Do you know how to filter results from a datatable? You can use dataview [^]for that purpose.

OK - I have a listview (details) that contains multiple rows with each row having multiple columns of data.
For each selected row, I want to create a text file record that contains the data from the multiple columns from the selected listview row.
Thanks!

Well, I haven't tried anything, as I have no clue. I looked at a bunch of examples of writing to text files, but none of them did what I am trying to do. I have certainly created text files from data before, but it has always just been single-column data written to a text file record.
So, if my listview rows look like:
Frankfurters REG_SZ C:\Windows\Blah\Blah
Hamburgers REG_SZ D:\SomewhereOverTheRainbow
then I want to take the data from the multiple columns on each row and create a text file record that looks like what is displayed above (for wach row) - I later want to be able to properly retrieve and separate the text file records into multiple columns for downstream manipulation.

Rather than just a plain text file, I would suggest either XML or CSV for this.

Thanks for the quick reply. I am a transplanted mainframer. Can you give me an example to write such a file? Either one is fine by me, as long as it is a commonly accessible format on remote machines.

You are opening a stream and writing from the start. You need to open the stream and write at the end.
You might find this article in MSDN on How to Open and Append to a ... file[^] useful.

You will need to get the FileStream yourself and make sure the stream is at the end of the file. You can then pass that to the StreamWriter, and it will add text on, rather than overwriting it.
Pretty simple:
FileStream fs = new FileStream(path + ":\\Batch_BDD_PROD\\nb\\TXT.txt", FileMode.Append);
StreamWriter monStreamWriter = new StreamWriter(fs);
try
{
monStreamWriter.WriteLine("Ma toute2 première ligne ...");
}
finally
{
monStreamWriter.Close();
}

I have problem in C# when I want to drop text on my textbox. If I drag tet form notepad it work ok, but if that text is html link I end up with link to the page, not link caption, withc I want.
I use thise
string tmp = (string)e.Data.GetData(DataFormats.Text);
How can I know what type of object is over control, if it is link from browser what should I do. I saw html type and I could parse it but my problem is how to know that object is link, and not a plain text.
Did I make myself clear?

Hi,
not sure I understand you correctly. You are dragging some text, which might be a URL? and if so, you want the content of that page rather than its URL?
If that is what you want, then you have to write code to that effect. Check the text starts with "http" and when it does, use WebRequest/WebResponse to get the content. If it fails, drop the URL; if it succeeds, drop the content (which could well be a lot of HTML mumbo jumbo, or an image, or just almost anything).
