I am trying to read in an XML document, add a record with a tag for the filename and write to a different XML document.I have been told I must use serialization.
View 2 RepliesI 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 RepliesHow 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 ...

Is 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

I just can't get it to serialize to this thing. I tried to generate the class using xsd but that produced a lot of garbage code and I really would like to maintain this by hand as it is easier than the monstrosity that xsd produced which didn't work anyway.
Reading binary data out of the database, and I need to convert it back into a Digital Persona fingerprint template. I'm not familiar with serialization and deserialization, Here's what I tried:
Dim rsBioData As SqlDataReader = SQL.ExecuteReader
Dim byteTemplate As Byte
Dim memStreamTemplate As MemoryStream
If rsBioData.HasRows Then
While rsBioData.Read
[Code] .....
I receive an error that template.DeSerialize(memStreamTemplate) does not create a value.
Here's how I serialized the object to place it into the database. I assume this part is working, since the binary data shows up in SQL server--just can't read it back out to see.
Dim str As New MemoryStream
Enroller.Template.Serialize(str)
Dim serializedTemplate As Byte() = str.ToArray()
SQL.Parameters.AddWithValue("biometricData", serializedTemplate)
I 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.
I have a question about serializing a Picturebox and it's child controls. I have a picturebox on my main form where a user can put new Picture boxes in.To a add a new Picturebox I say: Pictureboxmain.controls.add(Picturebox)But now I want to serialize this in a stream of bytes. I know that you can serialize an Arraylist as followed:[code]But is the same possible with a collection of controls?So now I tried this assuming the same method can be used with a control collection:[code]

I'm implementing some custom serialization (to byte array), and have run into a problem handling circular references.Example:
Class A
public MyBs as new List(of B)
End class
Class B
public MyParent as A
public MiscInt1 as integer[code]....
If I know that an instance of B will only ever be serialized through the serialization of an instance of A, then I can handle the setup of the MyParent reference from the instance of A and not even record that information inside the byte buffer for the instance of B.This doesn't feel quite right, but it might be the best solution.
The general idea of whats going on is i am trying to transfer a structure from one project to another using binary and sending through a TCP Stream. What I Did:In my server i serialized the structure Maps(Map) to a temp file. Then I read all the bytes from the temp file to my buffer and sent it off to my client project.

I have two experimental web services. One is an asmx contained within a .net web application. The other is a WCF service library being invoked from the web application.The asmx basically does everything I need, but I think WCF would be better, except that it doesn't do anything as I would expect after fiddling with the asmx service.For example, the same method behaves differently in each:
' ASMX
<WebMethod(BufferResponse:=True, EnableSession:=False)>
Function Test(aObject as Object) as Object
' object will have been successfully serializaed into a dictionary

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>

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