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.

I'm tryign to read a specific attribute from a xml website using this code:
'this is the url im trying to read, tmpIn is a string that complete the url:
Dim url As String = "http://maps.google.com/maps/geo?q=" & tmpIn & "&output=xml"
Dim reader As New XmlTextReader(url)

The problem is tmpIn takes diferents values (string) when the function is used and sometimes this works, and othertimes it gives an error (Invalid character in the given encoding. Line 9, position 15.), but is not because of the url, is when it tries to read the coordinates...
I am using VB.NET to read an XHTML file. I need my program to find every element within the XML structure which has the "class" attribute set to a specific value.IE: I need an array (or similar list) of all elements from the document which contain class="mytag".There is a list of several values I need to detect, all of which start with the same word 'mytag' followed by another word - so using a "contains" function seems sensible here

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.

ToSerializable is it possible instead of marking a Class with the <Serializable()> attribute?

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?

Does it do anything at all or it is only for documentation. If it is only for documentation, why documentation doesn't document it?For example these are two methods from System.Array class:
[ReliabilityContract(Consistency.MayCorruptInstance, Cer.MayFail)]
public static void Copy(Array sourceArray, Array destinationArray, int length)
[ReliabilityContract(Consistency.WillNotCorruptState, Cer.Success)]
public static void ConstrainedCopy(Array sourceArray, int sourceIndex, Array destinationArray, int destinationIndex, int length)
However documentation doesn't even mention that Copy or ConstrainedCopy are decorated.

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.
