Part Serialization Looping Or Even Linq?
Sep 8, 2010
I have a generic dictionary collection with a LOT of data classes, I am serializing this data and sending across IP. I need to cut down this collection into seperate messages as it is too large for my protocol to handle (and I am not changing that!).So, I would love a way to part serialize the data in say 25k (number not size) of classes, but I have not seen this done. I could manually loop through and create 25k lists of this data into new lists and then re-create at the other end, assuming I can use Join or AddRange. There is no GetRange on a collection.Is there a way in linq to select a range from a collection, or any other methods anyone has used?

Visual Studio 2008. .NET 3.5 VB 2008 or VB9 as it is also called. I have an XML file that I need to parse efficiently. I had completed the project by means of pulling the document into an array and pulling the variables I needed via looping through the array. This turned out to be very inefficient as the file is quite large.
I am now looking into using XmlDocument or Linq to XML so that I can pull the variables that I need without looping. I read that Linq is the fastest so I was trying to go that route.
I have searched all over the place for examples of parsing xml documents and I can't find exactly what I need.
My XML file is formatted somewhat like this:
Code:
<Folder>
<set>
[CODE]............
The idea is that I need to get those <fp> values for certain f_types only. Not only that, but it also needs to <set> specific. You will notice that the second "<set>" has a <num> Value of 2 within the <data> tags.
So... I need to find a way to search for say all the <fp>'s in set one that are of f_type 5 only, exlcuding all of set 2's f_type 5. This XML is not ideal but re-formatting the XML is not an option for me. I have to work with what I got.
After hours of googling all I was able to do was pull all the Element values for each <F> child nodes if they included a f_type value of 5. But... It does it for the whole doc, not just the 1st set like I need.
I will post what I have so far: It is not much but I can't find great info on using Linq to xml that does what I am trying to do.
[Code]:.....................
This doesn't even need to be enclosed in an XML block but for some reason it wouldn't work unless I put it into XML block.

I don't know if this is doable, maybe with Linq, but I have a List(Of MyType):
Public Class MyType
Property key As Char
Property description As String
End Class
And I want to create a Dictionary(Of Char, MyType) using the key field as the dictionary keys and the values in the List as the dictionary values, with something like:
New Dictionary(Of Char, MyType)(??)
Even if this is doable, internally it will loop through all the List items, I guess?

I've been using XML serialization for a while, and today I realized something really odd. If I have a new line right after a "dot" (.), when i deserialize, I lose the dot. Has anyone ever had this happen to them? The following is my serialization code:

I have a generic dictonary which is templated in the following manner:
[code...]
If I wanted to omit certain list items against arbitrary keys (that is the items that are in the list contained within the value part of each of the key value pairs making up the dictionary) given some arbitrary condition (lets say omitting list items where a list item contained the string "abc")
I would expect to able to create/project into a new dictionary which would contain entries which contained lists WITHOUT those items whose name contained "abc"
How do I achieve this using a Lambda expression?
I was trying something like this:

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

im making an application in vb.net (duh!) anyway i have created and coded the whole project and it performs exactly as i want it to (i dont need code help). my problem lies with the fact that my project is 2-3 parts
1.a setup form that gathers inital data about the enviroment stores this data encrypted in a config file. after inital setup this form is not displayed again. but needs to be run on both computers
2. the second form is the real application form im in the process of turning this part in to a background service anyway this form is the one that establishes the connection between two nodes it works correctly
3. the config files
anyway here is my problem i want to make this application distributional with just one file the (.exe) and have this .exe make everything else happen. it runs the setup form and creates the first config file which it does then it needs to produce a copy of just the second form and the config file to transfer to workstation #2 that will run independtly without the whole application which i cant make happen then it needs to turn both workstations application on by only starting one on either computer and invoke the other computer to start its corrosponding app also no idea how to make this happen any ideas or suggestions as to where to look to try to find my answers.im thinking i might need to make two seperate applications (a setup app, and the running app) and include them both in a project and use the setup.exe to to package them together this is a little side project that im making for my self to use to make programming a little easier so i plan on giving it out to some fellow students to test and tell me what they think so im not really worried about ease of use or complicated procedures yet but if it turns out to work and actually be of use to anyone else i would be willing to rewrite it to distribute to the masses but for now i just want it to work for me.

I have xml like this:

<ls>

Why is XMLSession.FileList.Count always 0. I hypothesize it has something to do with the declaration above it but I am not sure what is wrong with it. Maybe it can't accept a path, if not, how can I do it?

I've been serialising and deserialising .net objects using the XmlSerializer class without problem, however we now need somebody else to look at that data to perform some analysis on it.In order to help with that we've produced an XSD based on our class like so:
xsd.exe /t:DataClass Assembly.exe
The start of the XSD looks like this:
<?xml version="1.0" encoding="utf-8"?>
<xs:schema elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="DataClass" nillable="true" type="DataClass" />[code].....
Bizarly, the XML produced does not adhere to the XSD generated from the same class.My question then is, is there a way of telling the XmlSerializer to serialize the object based on a given XSD? As an aside, I've looked at other ways of fixing this: I've tried re-generating the classes from the generated XSD - this seemed to have the same problem.

I have a base class ("MyBaseClass") in a project called "BaseFramework" which is included in several solutions within the company. There are several derived class's in various projects throughout the company that inherit from "MyBaseClass". If I then create a List and add derived class's to it, it will not serialize. I realise that if I were attempting to serialize this list, and the base class and derived class were in the same project, I could simply apply the "XmlInclude" attribute to the base class and include all of the derived class's. This is however not possible across projects, because that would require a circular dependency.

I am attempting to solve the well known problem of automatically generated serialization assemblies in VS 2010, both VB.NET and C#. The "Generate Serialization Assemblies" option in project settings does nothing for non-web projects (see [URL]). Thus the calls to serializers generate file i/o exceptions that are very unfortunate, and for which there is no cure. The method suggested above does not appear to work with VS2010 and SGEN still runs with /proxytypes enabled.

DataContract XML serialization and XML attributes which is most interesting I have attempted to directly convert it to VB.NET, but it does not seem to give me the right results. All I get is the root element with no attributes:
<root xmlns="http://schemas.datacontract.org/2004/07/shutlBookingService" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"/>
how to add attributes to an element using VB.NET
OK Here's the code:
<ServiceContract()>
<AspNetCompatibilityRequirements(RequirementsMode:=AspNetCompatibilityRequirementsMode.Allowed)>
<ServiceBehavior(InstanceContextMode:=InstanceContextMode.PerCall)>
Public Class Service1
[code]....
The output is:
<Test xmlns="http://schemas.datacontract.org/2004/07/shutlBookingService" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"><success>0</success><timestamp>2011-10-22T09:28:52.7884244+01:00</timestamp></Test>
Which as you can see does not have success and timestamp as attributes.

I am creating a new windows program and I have used XML serialization to save the contents of my text boxes but when I try to open that file in the new application, no data is transferred. The code acts like it does everything fine and does not give me any errors, it just doesn't input the text back into the program.
Here is my code:
Imports System.Xml.Serialization
Imports System.IO
Imports System.Runtime.Serialization.Formatters.Soap

I've been cloning my objects using serialization for awhile, and typically its been quick, at least for my purposes. After a series of updates to these objects, however, now the serialization process is much slower. Trial-and-error has so far failed to pinpoint the cause. Some of the added elements to my object are:
1.binding lists
2. an inherited dictionary class
3. more internal references (the object is actually group of nested objects, and these internal objects have more references to each other than before)
I have been careful to avoid/eliminate references to external elements when cloning, as that can lead to a cascade of extra cloning. So I think the problem is with the object structure itself. This is my serialization routine:
Friend Function CloneObj(ByVal obj As Object) As Object
If Not obj.GetType.IsSerializable Then Throw New Exception("Object not serializable")
Dim bf As New System.Runtime.Serialization.Formatters.Binary.BinaryFormatter

Three questions:
1) Is the "CloneObject" function solution able to be used in my application?
2) If it is, what is the fix for the XCData typed objects?

I am making a FlowLayoutControl panel which the user can edit by dragging controls onto it in any required order. The controls are mainly (subclassed) Buttons and (subclassed) TextBoxes, plus perhaps a few labels. There might easily be several hundred of them interspersed at random. I need to be able to save the FlowLayoutPanel and/or its list of controls to a file, and then restore the whole thing again later when needed.If I am not mistaken, this will involve serialization -- a subject about which I presently know next to nothing. I have tried trawling the web for introductions and relevant examples, but I am suffering from information overload. There is so much written about serialization that I don't know where to start.As I can't spend too much time on this, I'm hoping there is some simple way through all the complications. Can anyone here explain, or point me to, the basics needed for saving a control like my one?

I've written one pgm that used byte serialization to save a file. It eventually morphed into a program and a library class (dll) so I could save/retrieve the byte serialization/desrerialization file from a different program that would use the same dll that originally serialized file in the first program. But, the first program seems to own the serialized file, not the DLL. The first progam is GenerateEventList and has the added reference Imports EventDBS which is the DLL. The second program EventDisplay also has Imports EventDBS to read the file. It produces the exception:

I've set up the serializer method which which serializes individual sublass objects if I declare them with their own type but not if I declared them as a derived (Animal).
