Serialize And Deserialize A Structure?
Aug 3, 2009Is it possible to serialize and deserialize a structure?
I think it isn't because the code I use will not work for a structure but it does work for other data types like an array, string etc

View 2 RepliesAdd XML Comment During Serialize/deserialize?
Mar 31, 2009I 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?
View 1 RepliesSerialize And Deserialize A Form?
Aug 7, 2010How 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 ...

maybe later add left/top/height/width/enabled/visible, etc, bu tfor not th econtrol name an its "value" are enough (text, value, lines, checked?, etc)

C# - Serialize List Of Objects In Android And Deserialize In WCF?
Apr 17, 2012I have an ArrayList in android that I'm trying to convert to a Base64 String, then passing that to a wcf service though JSON and the wcf service inserts the string into a database. Then I need to be able to read that from the database and deserialize it in a .NET application.
This is how I am serializing the ArrayList in android:
private String convertByteArrayToSave(byte[] b){
if(b != null){
return Base64.encodeToString(b,0,b.length,Base64.DEFAULT);
}else{

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.

VS 2008 - Serialize Array Of Structure To XML
Jun 3, 2010I desperately seek for a code sample to serialize an array of structure elements to a XML. To serialize a simple object of a structure I used:
Private Sub saveEntries()
Dim FS As New FileStream(path, FileMode.Create)
Dim XS As New XmlSerializer(GetType(personEntry))
XS.Serialize(FS, entries(0)) 'serialize first entry of an array - success
FS.Close()
End Sub
Structure looks like this:
<Serializable()> Public Structure personEntry
Dim name As String
Dim d, m, y As Integer
End Structure
Private path As String = "data_file.xml"
Public entries(2) As personEntry
But how to apply this to an array?

Class Structure - Large Structure That Has Lots Of Properties ?
Jan 5, 2010I'm new to VB 2008 after having spent a long time with VB6, so I apologize if this is a stupid question. But I'd really like to have this straightened out.
Let's say I have a pretty large structure that has lots of properties.
Code:
Now say that I want an internal database with about 10 instances of this structure total, describing, say, 10 different products that a store sells. When these values are loaded from a database, they remain totally static. (However, they can be different each time a program loads)
Now say that I have a class. Each instance of this class is a type of that BaseProduct structure. Meaning, each instance of the class pertains to one of the 10 types of products that the store sells. However, this class has additional properties that pertain specifically to each instance, which are not static.
Code:
Now, the problem here is... If I have 200 different transactions, each one contains an instance of BaseProduct. BaseProduct is HUGE, and is largely redundant (only 10 types possible), so I think it's a little silly to include a whole copy of it with EVERY transaction. However, the Transaction class really needs information regarding the base product it pertains to. Is there a way to, instead of declaring a New BaseProduct in the Transaction class, to simply make one of the properties of the Transaction class a pointer to a BaseProduct variable?
In VB6, I would accomplish this by making a BaseProduct(10) array, and then giving each Transaction an ID number referring to an entry in that array. But in VB 2008, using class structure, this is impossible. I can't define the BaseProduct(10) array outside of a class in a namespace, and if I define it in the actual application's form, then the class loses modularity since it relies on the application that's using it.
Converting Structure Within Structure To Byte Array For Socket
Aug 29, 2009I am trying to communicate with an external device and i am trying to send a byte array to the external device via sockets but i am always getting a response the message size is too small so i am not sure what i have done wrong. Between the data type there should be no alignment present and all numbers are represented in little endian format. The char array is not null terminated as mentioned in the protocol specifications.
I have to send data based on a struct that embeds 2 other struct. So here's my vb.net code for the struct used to convert to byte array and the sending part.

XML Deserialize To Class?
Jun 29, 2012Ok, 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" ?>

it's probably more cosmetic than anything but the logic just doesn't flow to look over 'server' and not 'servers'?!
