Ok, so I'm playing with some FTP profile files that are written in XML. I'm trying to get the program to be able to read the current users settings and fill in or remove servers they do or don't have access to. So the XML looks like
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<ftp>
<servers>
[code].....
it's probably more cosmetic than anything but the logic just doesn't flow to look over 'server' and not 'servers'?!

I have an XML document that I am deserializing (VB .NET 3.5 Framework), changing some values, and the serializing again. The original document has several XML Comments in it. When I go through all the deserialize/serialize all of the comments are lost. Is there a way to preserve the comments? If not, is there a way to add comments on serialization without having to walk through with the writer and manually add all of the comments back in the appropriate place?

How do I serialize and deserialize my main form (and its controls, subcontrols, their values, etc.)? Edit, for clarification. Currently I am writing the current value of each control to an .INI file, one by one and reading it back when the program is next run. Every time I add a new control, I have to remember to update that save/load .INI code.I just wondered if I can do it in one call, or a simple for loop iterating over all controls on the form.Btw, I use only simple controls like edit box, radio button, combo box, checkd listbox, the most complex thing I have is a datagrid, but even that is not linked to a databse.Accepted answer "can't. I will probably code my own, along the lines of ...

I was searching the most effective and elegant way do to the follows:
My function can be called while Filename is valid, corrupted, not exist
The function will just deserialize an XML object.
The main possible results are:
OK
File doesn't exist
Error in XML file
If I write this way, the reader won't be closed in case of corrupted file. IF I write the reader.close() inside finally block, It gaves me a warning about using read before assigning it a value.
So, how can I solve this inside the sub?

I'm having a problem to deserialize a XML to my class. It was working fine until a put the array det within the class. I put a watch just after the deserialization occurs (data = Ctype(...)), and I can see that all the informationswere loaded (ide, emit, dest) correctly except for the det element: The det whose nItem=1 attribute is loaded, but det whose nItem=2 attribute is not. With the watch, I could see that the object was loaded like a single variable, not a vector as I specified in the property declaration.
Below is where the deserialization happens when the button is clicked:

View 2 RepliesI'm deserializing some XML from an old application into an object in my current application. The old XML often has empty elements (<SomeElement />) which are currently deserialized as empty strings (""). I agree that this is the most appropriate behaviour, but it is a minor irritant; I'd rather they were deserialized as Nothing or ideally ignored - the effect would be the same. Is there a means of ignoring these elements? Or can I have them deserialized as Nothing?

The ultimate goal is to be able to be able to create a list of these shapes in the .NET app or android app and be able to read the list in the .NET app and android app no matter where it was created from. I'm able to it when you create the Shape from .NET and read it into android using WCF but creating it in android.

I'm programming an application in Visual Studio 2010, namely in VB.net. I have been developing an application which uses a derived class inherited from TreeView, with the aim of putting custom objects on the nodes. The method I have been using is to have a variable array against the node (of type object) which contains variables in custom classes to contain each of the variables associated with the node.
The two problems I had to overcome were, how to serialize a TreeView, and how to serialize an array of objects (of variable type). Good thing is I overcame both of these with some work of some other folks (and 3 days of my own work).[code]....
I am attempting to deserialize a simple JSON array to .NET objects using the JSON.NET library in visual basic.
For the life of me, I cannot figure out what I am doing wrong here. My JSON string deserializes into appropriate objects (9 in total), but none of the properties are populated.
My code:
Public Class result
Public Property id As Integer
Public Property vote_percentage As String
[Code]....
When using JSON.NET you have to have constructor methods (i.e. Sub New) in order for the properties to get set during the Deserialization call.
