ToSerializable is it possible instead of marking a Class with the <Serializable()> attribute?
as in the following Class.So you could maybe do:>>myObject.ToSerializable
<Serializable()> _Public Class ExampleClass
End Class
I have the following architecture for my project:UI -> Web Server -> App Server -> Database
I am using SOA architecture for my project. My Web Service is residing on AppServer having BL (Business Layer) / BO (Business Object) / DAL (Data Access Layer). I am exposing the BL using Web Service. I am getting the service reference to this Web Service at WebServer by creating the proxy using WSDL.exe. Now my question is:

I have a class that is serializable. I would like to compute the MD5 of it. I already had a function in the project to get a MD5 from a Stream, so I reused it, and created a function to convert an object to a memorystream. The code is as follows. Does anyone see any problems, but more to the point, is there an easier way to do this that I'm simply missing?

View 3 RepliesEDIT: SI have a web service which uses a class of functions in order to return data used in various business processes (via InfoPath). One of the functions takes a given SQLCommand object and executes it into a SQLDataReader. Now depending on the SQL command text used this may return one or many rows of one or many columns. So what is the best class for this function to return bearing in mind it needs to be serialized by the web service.
My existing code is:

How can i make one item in my class not serialize?
I have tried adding:

I'm trying to force an inherited class to use a custom attribute. I'm creating a class library where the user who wants to create an item will do so, but be forced to add an attribute (or visual studio will automatically add the default attribute) to their inherited class. Here is what I'm hoping to achieve:

I am trying to set the class attribute of a list item on page load. Dim liItem As HtmlGenericControl = DirectCast(Page.FindControl("default"),HtmlGenericControl)liItem.Attributes.Add("class", "active")
This code doesn't work, not quite sure why.This is the error it is generating "NullReferenceException: Object reference not set to an instance of an object"
Is there a way I can assign a value to a class attribute using a constant? would like to do this so that I don't have tocode a constant value in the attribute and then again inside the class.

I know that in a WebBrowser you can use Document.GetElementById to find an element by its name attribute, but I want to search the webpage for an element using the id or class atributes, how would it be possible to do this in a WebBrowser? I want to make it click on an image tag.
<td id="button1-cell"><img src="/static/button1.png" alt="Button 1" id="but1"></td>
Also, is it possible to InvokeMember("click") on divs?

I wonder, what is the most elegant way of dealing with the dbnull situation. I have a class, with attribute, let's say: "End_Date", which is being read from database. Type of this variant should be date, but as it's the "End_Date", there might be the situation that something haven't ended yet, and in the database in this field I have a null value.
Right now a deal with the problem this way:
Dim mEnd_Date
...
Public Property End_Date ()
Get
End_Date = mEnd_Date
End Get
Set(ByVal value)
mEnd_Date = value
End Set
End Property
But I am not sure if that's a good way as I don't declare variants as any datatype?

I had a strange problem editing a class in the property grid whereby the property grid would refresh incorrectly.I managed to reduce the problem down to a class with just two properties. I've included the code at the end to ease explanation.It basically boils down to a class with two properties. The first of which is expandable (a font)The class itself is expandable and also implements the CreateInstance method in the type converter.To see the problem, expand the font, edit, say 'Bold', and tab away. Two problems happen:
(1) The second property jumps up and ends up in the expanded font property.
(2) The '-' sign of the expanded font changes to a '+'.
The problem goes away by attaching ResfreshProperties(RefreshProperties.All) to the class. That's great, but I'd like to understand how it fixed the problem. I've had a look in reflector and can't find any examples of RefreshProperties being attached at the class level.

My application security from piracy depends upon fields in my databases. User has to activate the application, that writes Bought in my database. But the problem is if a new user installs my application and replaces all databases from some one who has bought key, the application also becomes active without buying key from me.
Is there any possibility that I could mark the databases to be recognized with the particular setup?
I've picked up some code from a colleague, and in one of his methods he has a boolean parameter: ByVal showProactiveChases As Boolean?. I had to look up the ? operator yesterday to see that it denotes a Nullable type. My question is, if I change it to: ByVal showProactiveChases As Nullable(Of Boolean), does the meaning remain the same? I think provided it doesn't change the meaning the second way is much more readable.
