Serialize And Deserialize A Form?
Aug 7, 2010
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 ...
[code]...
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)

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?

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 am trying to write a class to serialize/deserialize something as simple as:
<table border="1">
<tr>
<td>row 1, cell 1</td>
[Code]....
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.

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{
[Code]...
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 have a class called Truck and a form called frmTruck I have some code like this in a method. It recieves obj as Truck
Dim ms As New MemoryStream(1000)
Dim bf As New BinaryFormatter(Nothing, New StreamingContext(StreamingContextStates.Clone))
bf.Serialize(ms, obj)
To simplify my code, I have basically something like this for frmTruck:
public class frmTruck
private truckValue as Truck
public sub DoSomething()
[code]....
During the LoadTruckFromDatabase function I call the SerializeTruck method, here everything goes fine. But when I call the SerializeTruck just before End sub of DoSomething, it goes wrong I get an exception saying that frmTruck is not serializable My truckinstance doesn't have any references to frmTruck...

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 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?
Public Function DeSerializzaXML(ByVal FileName As String, ByRef tmpObj As Object, ByVal tmpClass As Type) As Boolean
Dim serializer As XmlSerializer
Dim reader As StreamReader

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:
Protected Sub btnDes_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnDes.Click
Dim data As New nf
'DeSerializacao XML
Dim Deserializer As New Serialization.XmlSerializer(GetType(nf))

I have inherited some code with a function that looks to Deserialize a Byte array that does not work with even simple arrays eg {1,2,3,4}it error out with "End of Stream encountered before parsing was completed"..Apart from the fact that it should work, I don't see how this does anything useful since all it seems to do is turn a byte array into an object.
