OK, then you need to keep a specific instance of the class you want to call, so you can work with it. If the method you're calling doesn't rely on any member variables, then it should be static.

The method is a void one, its not returning anything (as it should).

OK, that makes no sense. If it's got void, then it doesn't return anything. I think it's time you posted some code.

Hi,

I know it doenst return anything when its void, but it was more like extra info to your example where you showed me 2 methods that returned something.

This is my method:

public void WritingToXMLDoc(string elementString, string writeToXMLDoc)
{
this.writer.WriteElementString(elementString, writeToXMLDoc);

this.writer.WriteEndElement();

if (this.writer != null)
this.writer.Close();
}

Dude, that's some strange code. You check if writer is null, after using it twice, and if it's not, you call close on it. What does close do ? Does it stop WriteElementString from working later ? If this is the object I think it is, WriteEndElement is paired with WriteStartElement, so you're using it wrong.

Hi,

There is actually more code.

Complete class:

class XMLWriter
{
XmlWriterSettings settings = new XmlWriterSettings();
DateTime dateTimeNow = DateTime.Now;
XmlWriter writer = null;

public XMLWriter()
{
this.settings.Indent = true;
this.settings.IndentChars = "\t";
this.settings.OmitXmlDeclaration = true;
this.settings.NewLineOnAttributes = true;
this.settings.Encoding = Encoding.Default;
this.settings.ConformanceLevel = ConformanceLevel.Fragment;

this.writer = XmlWriter.Create("Testing.xml", settings);
this.writer.WriteStartElement("Information");
this.writer.WriteElementString("DateOfBuilding", dateTimeNow.ToShortDateString());
this.writer.WriteElementString("TimeOfBuilding", dateTimeNow.ToLongTimeString());
}

public void WritingToXMLDoc(string elementString, string writeToXMLDoc)
{
this.writer.WriteElementString(elementString, writeToXMLDoc);

this.writer.WriteEndElement();

this.writer.Flush();

if (this.writer != null)
this.writer.Close();
}
}

writer.Close(); is to stop writing and used for disposal.

If both your classes are in the same namespace, simply create an instance of your class and make a call to the method

...
XMLWriter myObject = new XMLWriter();
myObject.WritingToXMLDoc("elementString", "writeToXMLDoc");
...

I'm not sure if im on the right path here but i hope it helps

Why ?

Yustme wrote:

But that reads as if the method can only be called once - why ?

What are you expecting and what are you getting ?

Hi,

To write the date and time in the xml file too.

What do you suggets instead of using Close()?

Havent tested it all yet, but it writes the start and end element and the time and date.

But it's more than redundant, it will continue to point to the moment the file was created, which is not what Now means. And, if you only use it in one method, why is it even a member, assuming you had to create it at all ? Just use DateTime.Now.

Yustme wrote:

If you need to close the file, expose a method to do this, otherwise calling your other method once will close the file, but not make this clear.

OK, then at what point did you have a problem with what it's doing ? Or did I misunderstand you ?

Hi,
My reply regards sockets. They could help you but to use sockets you have to create a server and a client application. This could be a problem sometimes. I've worked a lot with sockets and they suited well in my applications. I don't know much about remoting but sockets require a server which listens for a connection and that could pe a con sometimes Smile | :)

Can you not use network file-sharing to achieve this?

To convert the video, import it in flash and from within. Moreover there are external FLV converters also available.
