I have been looking at some sample code, which includes the following line
Dim rule As FileSystemAccessRule = CType(Me.ACEDetails.SelectedNode.Tag, FileSystemAccessRule)
I'm a bit confused, because filesystemaccessrule has not been defined as a class anywhere in the code.

I have a web site project where I need to use the System.Security.Cryptography.Xml.SignedXml class. I added the Dll System.Security as a reference and imported the namespace into my project. It compiles successfully but when I debug the project I get a compilation error:
Compiler Error Message: BC30002: Type 'System.Security.Cryptography.Xml.SignedXml' is not defined.
What gives? Edit: I run Windows XP Pro 64bit OS

View 2 RepliesI have been having some trouble today with a User-Control of mine. Is what is happening is when I try to build an application with the control in it, the Form.Designer has an Error saying that Namespace.ControlClass is not defined. I have no idea what the problem might be and hope that one of you do.The weird thing is that the Control Builds just fine and I can drag it from toolbox to the form and THAT works. Also, it works just fine in Design-time. It didn't start erroring until either, I upgraded it to VS2010 or until I changed it a bit today. If necessary, I can post it here.

I would like to make a "deep copy" of a class object that I have defined. See Visual Basic 2005 Code below
Dim MyStuff1 as new MyClass
Dim MyStuff2 as new MyClass
mystuff1.getbyID(anID)
mystuff2 = mystuff1
Unfortunately the statement "mystuff2 = mystuff1" makes a "shallow copy" of mystuff1. Therefore, if mystuff1 is redefined then so is mystuff2. What do I have to do in MyClass to implement a deep copy method such that operations on mystuff1 and mystuff2 are independent?I would prefer something like
mystuff1.deepcopy(mystuff2)
or
mystuff2 = mystuff1.deepcopy()

I was knowing that For Each loop can only be applied to those classes that implement IEnumerable interface . But recently i accidentally wrote a code that is using For Each on my class's objects collection and my that class is not implementing IEnumerable interface .Below is the sample code that i am testing on :

Dim personList() As Person = New Person(2) {}
personList(0) = New Person("s1", "s2")

Suppose I want to build a class like

I am in the process of migrating from VB6 to VB 2008. In a pixel grid system I have thousands of cells with about 15 properties each. In VB6 I employed the user-defined datatype "udtCell()" as my array structure. Is this still a good approach - or should I perhaps make Cell a class?

to e.g. allow an object to give information to another object in such a way that the information can be mutated later wherever it goes. For example, in a Dictionary(Of String, Holder(Of SomeImmutableType)) it's possible to update the thing of SomeImmutableType without having to change the Dictionary itself (since the Dictionary's entry for a given key will always contain the same Holder object, that Holder object may be used as a lock).

so I used to mess around with C#, just a little. And someone had helped me make a class for Visual C# that was supposed to do the math parts for "internal structure" - which the program used for a part of its calculations and screen... Basically there were 2 options. Endo-Steel and Standard. The user would use a updownbox to determine weight of the machine and then internal structure was a % of that total. If it was standard then it was 10% of the overall weight, if it was Endo-Steel then it was 50% of standard (so 5% of total weight) rounded to next 0.5 (so .25 was .5, 1.25 was 1.5, 1.75 was 2.0, etc). I have the code for the C# class file for it, but want to make it in VB.
