Hi. I'm using an XmlTextWriter to write some stuff to an xml file.

I get this exception when I try to write the second node: Token StartElement in state Epilog would result in an invalid XML document.

This code snippet is for illustration purposes:

XmlTextWriter writer = new XmlTextWriter("test.xml", Encoding.UTF8);<br />
<br />
            writer.WriteStartDocument();<br />
            writer.WriteWhitespace(Environment.NewLine);<br />
<br />
            for (int i = 1; i <= 10; i++)<br />
            {<br />
                writer.WriteStartElement("node" + i.ToString());<br />
                writer.WriteValue("CodeProject");<br />
                writer.WriteEndElement();                <br />
            }<br />
            <br />
            writer.Close();

What am I missing or doing wrong?
It should be pretty straightforward, yet...

Thanks.

Every XML document has to have one ( and only one ) root node. Add a single root node, and you can have as many sibling or nested nodes inside that as you like.

Unless prolog creates DLLs that p/invoke can call, the answer is probalby no.

If your prolog compiler can build a standard c++ style dll you can p/invoke it the same way. If not you're sol without p#.

If there is no other probles you can use other controls.....
eg: C1flexGid is a good tool, in that you can do all these things

What is your problem ? Your previous requests are still visible. Why do you keep posting them ? Why not spend the time googling for an answer instead ?

You have asked this 3 times in the space of around 2.5 hours! Seriously, you need to learn some patience. If it is that urgent why not take a support call out with Microsoft. For a small feel they'll help you as a matter of priority.

How to programmatically add a checkbox column in datatable?

Hi!
I am developing application in C# (winform).I am reading data from a text file and storing it in a DataTable, then adding that DataTable to a DataSet and making that DataSet as DataSource of DataGridView control.

DataTable contains 5 columns, and one of them contains boolean value. i want to add a checkbox column in DataTable which will represent that boolean column.

i tried to add DataGridViewCheckBoxColumn into DataTable but error occured saying that DataTable can only have a column of type DataColumn.

Can any body tell me how can i add such column in DataTable. I cannot add a checkbox column in datagridview because mostly my datagridview displays more than 100000 records and when i try to add 100000 rows into datagridview it takes too much time.

Thanks in advance...

Regards,
Affan Ahmad Toor

Try to change the DataType og the particular column
like DataGridView.Clumns[index].. You can change the type to boolean

Install an ActiveX for IE ?

Hello,

I've written an ActiveX for IE in VS2005 C# .Net 2.0.
It supports RfID and GPS via COM-Port.
On my machine it runs great.

Now I wrote a setup with VS 2005.
I think I'm to set "vsdrpCOMSelfReg" for registering.
But it doesn't work.
It accepts only "vsdrpCOM"

After installation I called it in IE. It dosn't work.
When IE is open and I want to uninstall it by setup - Setup say "no, is in use."

I think, I'm not so far from target?!?
Can anyone help me?

I didn't find an good artikel in the internet.

Thanks a lot.

Additional:
In my IE I see the ActiveX in AddOns, but as File is listed "mscoree.dll"
What's that?
"Herausgeber" / Publisher is emty.
Maybe, it helps you.

Thanks a lot.

Hello guys in this forum .

in some programs i download as free trial , i saw some Api(s) calls written in ansi C and in C++ , these Api(s) enable me to get some information from the installed program or inject to it commands to be executed once i refer to these Apis in my application , so the question is:

how can i develop an application and expose some Api(s) like that for other developers to use to communicate with my application ??????

Thank you very much

The best way for people to communicate with your app is through WP_COPYDATA messages, it's simple and it's easy to impliment.
