Well there's probably a thousand and one things you could do - first question is the web service one you code as well? The reason I ask is that if so then it seems likely that you also have access to the database as well. If so I am curious why your company does not have some facility to create a more customer readable invoice reference in the first place. If this is something you can change can't you create a table which stores a more usable reference number against the customer and the guid (for example), then you could easily create a stored proc which would insert a new row for each new invoice for each new OR existing customer which could easily create a new invoice number again,
for example
id column, invoice Guid, Customer Id, Usable Invoice Item
1, 12345678-1234-1234-1234-1234567890AB, 123, 123-00001
2, 12345678-1234-1234-1234-1234567890BB, 123, 123-00002
Or even Mark-00001 if you wanted to use the customers Name as part of the reference.
If however you don't have access then your going to come somewhat unstuck (possibly) if you try and fiddle with the Guid for the invoice. The whole point of a guid is that it's supposed to be unique in time and place - the only way to enforce that is to use the whole Guid, otherwise there is a (slim) chance that you might end up getting the same number twice. Maybe if you laid out the code or company process we could offer better suggestions.
Mark.

The web service is provided by someone else unfortunately. It sounds like I'm going to have to find some other way of mapping the objects across the web service. Thanks anyway

Good day, everyone !
What is the difference between Soap and Binary Serilization ?
If you can, please show some examles.

Mainly the format of the serializtion result. The former serializes an object to SOAP (an XML-based format) whereas the latter serializes an object to a binary format. From this it follows that the reult of the SOAP serialization is to some extent human-readable and can be consumed by an XML processor whereas the result of the binary serialization will be smaller.

if u r using binay serializing so you will have to open a tcp port in your firewall through whihch your onjects ould be serialized and this is not secure because you are opening your port even for untrusted users , but while using soap serialization which is xml based and xml data can be transmitted over http port which is port 80 so there is no need to open any additional port for transmitting or receiving soap serialized objects, on other hand all the languages today support xml parsing you just send them serialized xml object and they will parse it according to their language xml parset (e.g system.xml on dot net).

One more major difference: Problems with Xml serialization
a) you're referenced objects are no longer referenced by reference after deserialization. (i cant beleive i used word 'reference' thrice in a sentence)
b) cannot handle circular reference (e.g. Company has employees, Employee has refrence to parent Company object)
c) Large file size
Assume you have a classes Company and Employee.
Company c = new Company("ABC");
Employee e1 = new Employee("Jack");
Employee e2 = new Employee("John");
e1.Company = c;
e2.Company = c;
ArrayList employees = new ArrayList();
employees.Add(e1);
employees.Add(e2);
------------------------------------
After serialization...
<employeeslist>
<employee>
<name>Jack
<company>
... company details
<employee>
<name>John
<company>
... company details

Search the articles or the net in general for this topic and almost certainly you will get many results.

You can start by looking at TextBox.TextChanged event handler.
Good luck
If you can't find time to do it right the first time how are you going to find time to do it again?

Using C# and .NET, I need to make an XML document. I've searched and all i can find is info on using XmlReader and XmlWriter, or XmlDocument after loading an already existing XML file. Problem is, I don't have or need a file. I really can't even make the file, due to security issues. I need to be able to make the XML structure in memory. Below is a sample of what I've tried so far, and the error it gives me.
XmlDocument doc = new XmlDocument();<br />
XmlNode node;<br />
<br />
node = doc.CreateTextNode( "This is a text node." );<br />
doc.AppendChild( node ); <-- System.InvalidOperationException was unhandled, "The specified node cannot be inserted as the valid child of this node, because the specified node is the wrong type."
I know I have all the right "using's", it compiles fine. My guess is the XmlDocument isn't initialized correctly, but i can't find info on how else to do so.
Any help would be greatly appreciated.

A text node cannot be a direct child of an XML document. You have to create an element first that will become the root element of your document and add all other content to this element.

Ya, a few hours after I posted, after trying several different things, I figured it out. I'll post what I did, for anyone else having the same problem.
XmlDocument doc = new XmlDocument();<br />
XmlNode node1;<br />
XmlNode node2;<br />
<br />
doc.AppendChild( doc.CreateNode( XmlNodeType.Element,<br />
"XMLRoot", string.Empty ) );<br />
<br />
node1 = doc.CreateNode( XmlNodeType.Element, "Element", null );<br />
<br />
node2 = doc.CreateTextNode( "Text" );<br />
node2.InnerText = "A text node";<br />
node1.AppendChild( node2 );<br />
<br />
doc.SelectSingleNode( "XMLRoot" ).AppendChild( node1 );<br />
<br />
doc.Save( Console.Out );<br />
<br />
<br />
Apparently, nodes can only be added to Element nodes. I haven't worked much with XML, so perhaps this is obvious to others.

Some remarks:
1. If you want to create an element why don't you use the CreateElement method. This way you do not need to pass a XmlNodeType value and furthermore the method as an overload where you do not need to specify a namespace URI (comes in handy for creating unqualified elements).
2. The CreateTextNode method already takes the text of the text node as argument, so by passing in "Text" and afterwards setting the InnerText property of the created node to "A text node" is redundant. Directly pass "A text node" to the CreateTextNode method.
3. Using SelectSingleNode to get the root element of your document is quite inefficient. You can access the root element of a document directly via the XmlDocument.DocumentElement property. As an alternative you could assign the root node to a variable after creating it and then append it (as done with the text node).

I can see what you're saying. Certainly the code I posted an be cleaned up and made more efficient. I was working on this last night, and what I posted was written at 1 in the morning. It worked, gave me the output I was looking for, I was happy, and went to bed. I'll clean it up later, and let you know if I see anything other than what you mentioned. Thanks for the help though.

I'm well aware that during the process of learning one does not always find the best way at first and is happy to find a way that works anyhow. So my posting was not intended to criticize you. Just wanted to give you some pointers what can be optimized.

Hi everyone,

Two things are possible.
1 - the .NET framework is broken ( report it to Microsoft )
2 - your code has an error ( we can't tell what the error is without seeing it )
Do you start your timer ? How do you know it doesn't get called, do you set a breakpoint, or are you assuming that because you don't see the end result you hoped for ?

Hi I'm new to programming, currently I'm learning C#.
I am attempting to build an audio app DJ style and using C# and it is proving a challenge.
My questions is should I be using C# for building audio apps or is there a better programming langauge more suited to the task?
Thank you
Mike

That's a ludicrous thing for someone 'new to programming' to attempt. Learn to program first, then worry about libraries like DirectX, or using components like the Windows Media Player control.

C++ is more powerful, but I wrote a video jukebox in C# which is in constant use in clubs and pubs in the country I live in, so there's every reason to expect you can do what you want in C#, if you learn it first.
