I tryed using serialization I might be using the wrong thing though what im trying to do is to serialize a class to a .bin file and then use it from another application, is there a way to change the specification of the binary formater this way it works in two different Vb.NET projectS??

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.
View 1 RepliesI 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.

I have a problem whereby I cannot debug a c# silverlight application project that is hosted from within a visual basic web application. I add breakpoints to the main App constructor and the symbols are loaded ok but my breakpoints are never hit. I have concluded that it is a vb/c# interop problem as to test i did the following.
Created a new c# web application project
Added a c# silverlight application
Added a new vb web application project
Added references to the silverlight project from both web apps
set a breakpoint in App.xaml.cs constructor
if i run the c# webapp the break points are hit whereas if i run the vb webapp they are not.

I have written a few different applications in the past few years, all of which are related in that they help users creating maps/levels for a certain game. I would like to 'bundle' all these applications together, into one application (and will later add more functionality to that). In it's most basic form, it would simply be one single Form with buttons, where each button opens the corresponding application.

What it is the option Enable application framework that I found in Visual Studio under VB.NET WPF projects Application settings?I found it enabled by default and the "Shutdown mode" configured as "On last windows close". But for me is not really clear what does it mean that setting and also the other settings listed in that combo box.

View 3 RepliesI have a windows forms application with one exe and several dlls(Class libraries) in a single solution. The application uses common data that is used across all the dlls. I would like to load the data when the application is starting up and use the loaded data at various points in the dlls so that I do not have to load the common data again and again. How can I share the data loaded in main EXE across the DLLs?
View 2 RepliesI 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

I have a solution with two projects. The main project connects to the second project via a reference, and the reference path is local to my machine. It looks like it references the .exe file.So when I publish the main project (ClickOnce), i get the following error:
Application validation did not succeed. Unable to continue.In the log file, under Error Details, it says
System.Deployment.Application.InvalidDeploymentException (RefDefValidation)
- Reference in the manifest does not match the identity of the download assembly Project2.exe
- Source: System.Deployment
How can I include this second project? Should I publish it, then reference the published files? What do i reference? The .application file?Is there a way to just include this second project, so when I do publish the main project, the second one just goes along with it?
I have xml like this:

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.

The output is:

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.

View 2 RepliesI'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

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?
View 5 RepliesI'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:
