The default accessibility for a class is internal, so as long as the class is used within the same assembly, it should work fine. Otherwise, as you said, the class needs to be public.

I am trying to read an XML file and break it up into smaller chunks but am having real problems in doing so as I have never used XML (and am new to C#), so would appreciate any help possible. The problem is in two parts:
1) I have a file with some beginning header info, i.e. along the lines of:
<?xml version=”1.0” encoding=ISO-8859-1” ?>
<!—some comments -->
<message xmlns:xsi=”http….”…>
<header>
<more header stuff>text here</more header stuff>
<some more header stuff>text here</some more header stuff>
</header>
I wish to add this to every new XML document I create but am having problems when trying to write it.
2) I then wish to read a large XML document and cycle through it, copying each record to a new file that I have created (with the above header info), until I have 100 records, then start again. The format of the records is:
<Record>
<attribute1>blah blah</attribute1>
<attribute2>blah blah</attribute2>
<attribute3>blah blah</attribute3>
</Record>
I know that I need a for-loop to do this, but not having any experience of XML with C#, I don’t know what is needed to complete this task. Can anybody help please?!
Thank you to all who can assist!

Have a look at the System.Xml.XmlDocument[^] and related classes. They allow you to load the the XML file into memory and perform operations like addition/removal of nodes. In particular, pay attention to the CreateNode[^] and Save[^] methods.

Thanks for your help Senthil. But do you (or anybody) have anything a bit simpler you could point me towards; something that would make a bit more sense a bit quicker, rather than having to read class definitions?
Thanks

Thanks for your help so far. I have been working away and had some success; I can create a new XML file which prints the header info, then begins to cycle through and print the records as expected (hoped!). However, it crashes at the end with the following error:
"A name was started with an invalid character. Error processing resource 'file:///C:/..."
Also, the second file is created but cannot even be displayed, as it shows the following error:
"XML document must have a top level element. Error processing resource 'file:///C:/..."
My code for this is as follows:
while (fileReader != null)
{
// Create a file to write to
XmlTextWriter fileWriter = new XmlTextWriter(directory + "\\Output" + x + " myFile.xml", System.Text.Encoding.GetEncoding("ISO-8859-1"));//null);//System.Text.Encoding.UTF8);
// Write the header details to the new file
fileWriter.WriteProcessingInstruction("xml", "version='1.0' encoding='ISO-8859-1'");
fileWriter.WriteStartElement("!-- My comments go here --");
fileWriter.WriteStartElement("message");
fileWriter.WriteAttributeString("xmlns", "xsi", null, "http://www.w3.org/2001/XMLSchema-instance");
fileWriter.WriteAttributeString("xsi", "noNamespaceSchemaLocation", null, "myXSDdoc.xsd");
// Add 'messageHeader' as the element to enclose records in the file
while (fileReader.Name != "messageHeader")
{
fileReader.Read();
}
fileWriter.WriteNode(fileReader, true);
// Write each row to the file, until 1000 records have been written
for (int i = 1; i <= 1001; i++)
{
while (fileReader.Name != "KeyRecord")
fileReader.Read();
fileWriter.WriteNode(fileReader, true);
fileWriter.Flush();
}
// Tidy up and close the file so that a new one can be opened
fileWriter.WriteEndElement();
fileWriter.Close();
x++;
}
Can anybody please help me with these errors? Thanks

Please help me.

The main way to do this is to create delegates, so that your forms can call functions within each other. If you want something more quick and dirty, pass an instance of each form to the other form, and make the methods public.
We need a FAQ, and this needs to be the first item on it. In fact, I thought we had one ?

This has been a long....long...did I say long running feeling. Heath Stewart and I started one about 3 years ago. I don't think it ever came to fruition.

you could use of this function such as using a function in a class .
Create a new instanse of ur form class and then call your function
|
|

See this article: Passing values between Forms in .NET[^]
It passes values through properties - but properties are just syntactic sugar over getter and setter methods, so it works just as well for calling regular methods.

Morning all,
I was wondering if somebody could answer a simple question.
Using VS2005 I have a C# form connected to a Typed DataSet.
On this form I have a number of Textboxes that are DataBound to a Binding source, this is all fine, but I want to allow the user to edit the text without direct updates to the datasource. To implement this, I call suspendbinding on the binding source, but this clears the text boxes. Is there any way to prevent the text boxes clearing when suspend is called??
Thanks
Paul

Sounds great. I need a program that displays medical images across 5 monitors, with a variety of client tools such as zoom and so on, and which downloads those images via a webservice. How about if I do your work, you can do mine ?
In other words, this site isn't here to do your job for you, or your homework, whatever it is you're trying to get away with not doing. Read your spec/homework, ( if it's work, then you'd do better to return it and explain why you are not competent to do it ), and assuming it's homework, talk to your lecturer, read your resource materials. If, after doing all that and trying to do your homework, you're stuck, by all means ask questions here.
If you need an inventory control program for your business, I'm way too busy, but I'm sure there's plenty of people here who could offer you their contract rates.

Hi
I have one column which contains numeric data. If data is 0 I would like to display ''.
How can I do that? Set any format?
thanks for help

maybe you can use a filter;
xDataSet.xtable.DefaultView.RowFilter =" xcolumn LIKE '% 0 %' ";
dataGridView1.DataSource = DataSet.xtable.DefaultView ;
with this only the cells with a 0 are displayed
