I am trying to convert a method from VB6 to VB.NET and having some issues with StrPtr and VarPtr not being supported in VB.NET anymore. Here is the method having a problem. From what I know, I am looking to get the memory location of the objects to pass to the SendMessageCDS() method.

I've run some code which extracts data from a database and presents it into a Datalist. It works fine when the script is on the aspx file, but when I transfer it to a code behind I get the following error
Compiler Error Message: BC30451: Name 'showIt' is not declared.
(showIt is the ID of the Datalist)Obviously, the Datalist markup is in my aspx page, and the script is in the code behind .vb file.As I say, it all works when the scripts are all on the one .aspx file.The code in the code behind is: (I've skipped the SQL and connection strings to keep this post concise)

How can you use XML that you have declared within your code? Also, what is the correct way to put it in your code?

This timer code is for VB6 and worked fine, It's to change the timer seconds into minutes, I'm not sure how to make this work for 2008 though.

Timer1.Interval = 1000 ' set timer to 1 sec intervals.

I am trying to get a subset of locally declared methods in a webform code behind using GetMethods but cannot figure out the proper BindingFlags settings (see code below)....and some further specific questions:
1) Is it possible to differentiate between Procedures and Functions?
2) Furthermore, I only want to fetch a certain subset of these....is there some way I can decorate the ones I want with an attribute, and then further filter based on that?
Private Sub LoadFunctions()
Dim thisClass As Type = Me.GetType
For Each method As MethodInfo In thisClass.GetMethods(BindingFlags.Instance Or BindingFlags.Public Or BindingFlags.DeclaredOnly)

In re-engineering a windows forms application, I find that a lot of code-behind in the various form classes is duplicative and I'm trying to centralize as many procedures as possible into a base class which can be inherited and used by the subclassed forms.
This process seems to be going well and is making the code in my subclasses much simpler and hopefully easier to maintain, but I'm not sure where to draw the line between leaving code in the subclasses and engineering for generic resusability and moving it to the base class.
Specifically, in some subclasses I have code which manipulates variables and objects specific to the subclass, and although I could move the code-behind into the base class, the base class code references specific objects which are needed to compile. For example, each subclass manipulates a databound datagridview and form detail controls which allows the user to select between multi-record and detailed single-record views of a datatable.
In Visual Basic 2008 do I need to declare dummy data objects in the base class so that the base class will compile? Or is there a way to indicate that the data objects will be provided by the subclass?
The following is a screenshot of the problem: What can I do?

The function checks for the input only the digits.

Quick background: I have a VB.NET application in which I was previously using ConfigurationSettings.AppSettings to read from app.config, and got an error message to change it to System.Configuration.ConfigurationManager.AppSettings (as the first way is now obsolete)I did so, and I even have a reference to System.Configuration.dll AND the Imports statement at the top, but I am getting a "Name ConfigurationManager not declared" error message. Any suggestions?
CODE:
It's pretty straightforward - I'm just checking if something exists, and if it does, I read from it:
If Not Exists(ConfigurationManager.AppSettings.Get(rep & "Email")) Then
Return False
End If
message = ReadAllText(ConfigurationManager.AppSettings.Get(rep & "Email"))
