According to a mspress book (MCTS for Exam 70-536 .NET 2.0): You might have version compatibility issues if you ever attempt to deserialize an object that has been serialized by an earlier version of your application. Specifically, if you add a member to a custom class and attempt to deserialize an object that lacks that member, the runtime will throw an exception. In other words, if you add a member to a class in version 3.1 of your application, it will not be able to deserialize an object created by version 3.0 of your application.
Now... As curious as I am I went and created a project, serialized a class, added a new member and attempted to deserialize the class to the new object. To my surprise it worked and the newly created member was set to null by default (even if it had another default value).

I'm writing a solution in VB.NET that consists of a number of different components (UI manager, Outlook add-in, etc.). In the main UI program I'm serializing out an arraylist to a data file that contains the data the other components will need to do their jobs. That part works fine, and I can serialize and deserialize with no problem. Now I want to read (deserialize ) in the data in my Outlook add-in, and I ran into the dreaded 'Unable to find assembly' issue where it's looking for the original assembly that serialized the data. I found a hint for workaround

I have a Problem Serializing and Deserializing a 2-Dimensional Array. I have a 5x5 Integer Array and want it to format it into one String (like Base64) to store it as an Attribute in a XML-File.
To store it i use this code:

To Read and Format it i tried following :

But Deserialize only Returns an Integer not an Array. How i can Deserialize an complete Array ?
This is my first post on here--I've been teaching myself VB via forums like this and MSDN for about 2 years now. I'm programming a computerized economics experiment, and I'm using a communications package that a guy I worked with developed. He and I have been going back and forth trying to figure out what the heck is going on.
The upshot of the communications package is that there's a serializeable MQMessage class that we send back and forth, essentially just a package of an integer (Type), string (Text), and Object (Data). Most of the time, this goes according to plan.
The problem is this: If the client receives two or more messages back-to-back, the client stops raising the MessageArrived event. (and presumably, the same would hold true for the server--I should test this, but jeez-oh-man, I've been running test after test for the last week).It's still connected, as on disconnect it throws the "Socket forcibly closed" exception. When it receives multiple messages sequentially, it's still receiving the data, it just never knows when the first message ends, and the buffer just keeps filling and filling. The problem seems to be that it can never successfully Deserialize the MQMessage object, and so it returns Nothing on the getCompletedMessage function and just keeps adding to the buffer (ABuffer.Length goes 1024, 2048, etc.).
I'm saving potentially very large amounts of data to disk as a single serialized class. But there is a sub class that I would like to be able to retrieve and write back to the disk without having to read the entire file or write back the entire file. Trust me, my reasons for doing this are good, and the design behind this is more than correct.In VB6 this is very easily done. A single statement gets the portion of the data you want from the front of the file and saves it straight to the Type it belongs to, flawlessly. Likewise, if the dimensions of the data haven't changed, but only the values, then Put can be used to save it right back to the file without disturbing the integrity of the entire file.When needed, the entire file is read into a larger structure, and the entire file is put back, but only when necessary. Most of the time the only information being read from and written to the file are in the first few hundred kilobytes of the file.
Now that I've got serialization working, I'm trying to use it to read (deserialize) only the first member of the class serialized to disk. I haven't been able to find any examples of this anywhere that have lead me toward making the sort of progress I'm hoping for.So I suppose the first question is this: Is it possible to read only part of a serialized class from the open file stream? Specifically, in one case I want to read the first two integers stored in the class. In another case I want to read only the first block (sub class) from the open file stream. In both cases I do not want to read the entire file, but just what I'm interested in starting from block 0. I don't need to write back the integers to the first file, but I do need to write back the block to the second.Assuming that the answer to the above is yes. My second question would then be: How is this done? I want to work with the file stream already open rather than opening and closing file streams over and over.I
The following (abysmal) code demonstrates how standard serialize/de-serialize in VB loses the CR when on de-serialize. This can be overcome by applying 'XmlAttribute(DataType:="string")' to Description. Why does it do this? I would like to fix this without applying a 'LF' -> 'CR''LF' in every affected class. This is fixing a bug in existing XML files generated without the XmlAttribute!

I am having the same issues as per this question: WCF not deserializing JSON input..I am at a loss and desperate for a solution. I have scoured the net for answers, but I have found only this question that matches my exact problem. My datacontract parameter is also nothing when the service starts.I have tried the points of the answer in the question above, but they provide me with no clues (The web service executes OK -I am not getting any exceptions - and I can't see what the deserializer is doing - or not doing as the case may be).I am using POST, due to the size of the nested JSON.If more detailed information is needed, I will provide it on request.[code]
View 2 RepliesI'm developing a program that captures a bunch of information entered by a user on a tab form into five different structured arrays. I want the data to be saved into a single file and reloaded by the program into a similarly built series of structured arrays through a different form.If I understand the process of serializing collections right, I create a single ArrayList variable to capture each of the five Structured arrays.[code]
1. Do I have to declare one variable of the same type as the one in the first element of the ArrayList, or does having the public variable declared in the Class that's going to take this information already cover that?
2. Once I deserialize into the newly declared Rules ArrayList in the new form, is it a simple matter of setting the duplicated variables in the new form equal to the relevant element in the ArrayList? For example, if I have a new Public Roster As RosterDesc variable declared, can I set it equal to Rules(0) and it would automatically populate every element in the same order as they were created in the original form?
I am trying to deserialize a JSON string that looks like so: {'type':'clientlist','client_list':[]} I am using JavaScriptSerializer() to do it. For some reason the JavaScriptSerializer() is choking on the member 'client_list'. It doesn't give very good info. The error it gives is:

I have a situation where I serialized data from a dataset to an xml file as a method of backup.I am trying to get the data deserialized back to the dataset.But for some reason, I cannot get the data to persist back to the DB.I don't receive any error messages either.The first chunk of code is the serialization code and the second chunk is the deserialization code.I can show that the deserialization back to the dataset is complete because this code in the 2nd block DataGridView2.DataSource = Movie_dbDataSet.movie_tb - displays the data in correct form all it is all there in the datagridview2.I call the update method but it does not get persisted back to the db.[code]

The error is Value of type '1-dimensional array of string' cannot be converted to 'String'.

Basically I have a webresponse stream:dim lol as string = readstream.tostring there is a lot of information within the string but only one link starting with http: located near the end of the string - however there is no constant character point where I can start... (i.e. 38)
I want to extract the link from the string i.e. dog cat plane car [URL]..that is approximately how it looks above - words and url substituted I want to just extract [URL]..I had an idea of parsing the string from http: to the end Then after that splitting the string up again to remove the }], however it does not return anything

Problem: Your task is to take input from the user in string and give the following options to the user in a menu.
1- Find a String
2- Create sub-string
3- Erase a portion of a sting
4- Replace a word in the string
5- Count number of words and characters in the string without spaces.
6- Capitalize first character of each new sentence and convert the rest
of the characters to lower case.
7- Sort all the words in alphabetical order. (Use Bubble sort algorithm to perform sorting).
To perform all the above mentioned tasks you can only use pointers. Create a function to perform every task.
