Serialize A Property Including Namespace In VB?
Aug 28, 2009
My problem is quite simple and I am probably just not using the correct syntax, I am trying to add an attribute in my class so that when I serailaize the object it will include the schemalocation attribute in my generated XML.In C# I would be looking at doing something like this:
[XmlAttributeAttribute("schemaLocation", Namespace = "xsi")]
Public Property schemaLocation() As String
Get
Return "http://www.w3.org/2001/XMLSchema MyNewsItem.xsd"
[code]....
However in VB Im unable to find the translation for [XmlAttributeAttribute("schemaLocation", Namespace = "xsi")]

Basically I have created an object that has a graphicspath as one of its properties... and i want to serialize it...
I was basically wondering if i could somehow automate the serializing of the GraphicsPath to another object (for the purposes of serializing since the graphicspath cannot be natively serialized)
eg serialize it to a list of the following class:
vb
<Serializable()> _
Public Class sPath
Public PathPoints() As PointF
[Code].....

I want to use project B property in project A. Hence, I added project B to my solution. How can i use the property of B? Can someone guide me? i'm new to vb.net..To my knowledge, we need to use namespace and create a new instance. Could someone guide me on how to use namespace for this purpose?

I'm experimenting with xml literals in vb.net and there's something I don't get. Here's a small sample that illustrates the problem. I'm adding two PropertyGroup nodes to an empty Visual Studio project. The first one is added as xml literal, the second as new XElement:
Imports <xmlns="[URL]">
Module MyModule
Sub Main()
Dim vbproj = <?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" DefaultTargets="Build" xmlns="[URL]">
[Code] .....
This code writes the following output:
<Project ToolsVersion="4.0" DefaultTargets="Build" xmlns="[URL]">
<PropertyGroup xmlns="[URL]"></PropertyGroup>
<PropertyGroup />
</Project>
As you can see, the first PropertyGroup node contains a redundant xmlns declaration. Why is that, and can it be avoided?

I got some set of base classes within one namespace and few sets of derived classes in other namespaces. Everything in one project.[code]...
OK, it can be done declaring .SubElements as Protected in BaseElement class. But in this case I cannot access this property from other classes in Base namespace that are not derived from it.
I tried adding Friend keyword, but it made this property visible when I'm instantiating derived classes too.
So... any way to hide some properties when using derived classes while being able to use them using base class?

I need to read an xml document from a database record into an XDocument object in order for it to be deserialized. So that the deserialization will work, I need to apply a specific namespace to each of the level 1 elements. So XML looks a bit like this:
[Code]...
How do I prevent the blank/empty namespace being added to each child element of the element to which the required namespace has been applied?

This class is located in the namespace Acme.Infrastructure.Interface.A class with the same name EventArgs exists in the System namespace.In another project in my solution I have a class Acme.BusinessModules.MyModule.MyClass.When attempting to use the EventArgs class I have to fully qualify the class name or the compiler thinks I am using the System.EventArgs class.My understanding of namespace resolution was that the compiler would first look for the class in the current namespace, and then its parents. It seems that the compiler checks in System before it checks in sibling namespaces. Is it correct that System is checked before the sibling? Or is this behaviour caused by other issues (Imports order?)?

I'm having some very weird issues with interfaces right now.
I have a very simple setup. In one of my class, I have a Property implementing a Property from an Interface.
In my class it's like:
Private _oForm As IForm
Public Property Form As IForm Implements IContainer.Form
Set(value As IForm)
[Code]...
I have like dozens of interfaces like this working throughout my project and I can't believe this simple one can't work!

This is for a web project so i have several classes that inherit from Web.UI.
I only want to serialize very particular properties (basically, only local properties)
I'm aware of the XMLIgnore property that can be placed on a property to ignore items, but this won't work in my context since that would require modifying a bunch of stuff that i really don't want to modify (and probably can't).
So how do i tell the xml serializer to ignore everything except for X and Y or tell it to seralize just X and Y?
i could just create my own xml in a string builder or something and if that's the only way, so be it. however i'm looking for a method that will employ the built in XML stuff.

I'm writing a test application in order to figure out how to serialize a structure to XML. I can not get the following code to work for me and it's not obvious to me.
The following defines the structures I am attempting to serialize. I think I have the xml decoration correct - but the errors I'm receiving (see below) don't really give me much information.

I need a way to transfer a compiled assembly from client to the server and be able to store that in the database or in a file in such a way that I can grab those bytes on the "to" side and re-load assembly. Is there a way to do it. To clarify, I have a winforms application that will generate code and compile it based on some metadata. Now I need to be able to transfer this to a web site and store it somehow, but I don't want a dll (because it can be de-compiled). I would then have a "server" program on the to side, that would load this in memory. I could just transfer encrypted source code, but I thought I could just transfer compiled assembly.

I am having an issue using BinaryFormatter.Serialize. I have this generic extension method to "clone" an object via binary serialization:
[Code]...
This is killing performance. Anything more that about 7 or 8 clones brings the app to a halt. Why would this happen? The USING block ought to ensure the MemoryString is disposed of, right? Shouldn't a new MemoryString be created each time? I would think since the same original Mode object is the source for the serialization, the MemoryString length would be the same.

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?

I have a 3D Engine which renders a 3D World onto any vb.net object with an HWND(Handle) -Picturebox or Form using Direct3D.What I'd like to do is stream that image over my LAN. I know its probably a weird idea, but I have a plan.Since the image is 'rendered' onto the object, the objects 'Image' Property is null, so sending that to a byte array doesn't do any good.Now, I've tried using the picturebox.drawtobitmap function, but it is far to slow for what I'm intending.I've used several functions in the Graphics control to try and get the image data off that picturebox, but to no avail.I've even tried sampling the surface data from Direct3D but none of these objects are able to be converted to a byte array.

An unhandled exception of type 'System.InvalidOperationException' occurred in System.Web.Extensions.dll Additional information: A circular reference was detected while serializing an object of type 'System.Globalization.CultureInfo'I even make the simplest datatable with only 1 column and 1 row, but it just won't serialize it?
