What should go into the top level namespace? For example, if I have MyAPI.WebLogic,MyAPI.Compression, etc. If I put classes into the top level namespace, am I violating the principle of encapsulation?

When I use PUBLIC above a Class definition, the compiler gives an error. When I put PUBLIC under the Class definition, I have to qualify the variable with the class name in order to use it in another module.
The documentation says Public can be used at Namespace level. Is there a way to be able to just use the variable name, without any qualifier, across my entire project?
I've started to use a Vista machine for development. In case it is significant: I'm using MSBee so that I can code in the Visual Studio 2005 IDE while still building against the 1.1 framework.On the Vista machine, when I tried to build a particular vb project, I got this error:
error BC30464: Namespace or type'Compatibility' in the project-level Imports 'Microsoft.VisualBasic.Compatibility' cannot be found.
The same project built fine on my old XP machine. I checked in this folder on my Vista machine:
C:windowsmicrosoft.netFrameworkv1.1.4322
...and sure enough, "Microsoft.VisualBasic.Compatibility.dll" was missing. So was "Microsoft.VisualBasic.Compatibility.Data.dll". Copying them from my XP machine to my Vista machine allowed me to build the project successfully.I'm just a bit puzzled as to why this happened. Why was "Microsoft.VisualBasic.Compatibility.dll" missing? I'm also not very comfortable with my chosen solution - copying the DLL manually. It works, but surely there must be a better way.
As far as the configuration:
Vista:
.Net Framework 1.1
.Net Framework 1.1 SP1
.Net Framework 1.1 SDK

I am creating an Excel add-in written in VB.NET. I would like to bind KeyDown and KeyUp events to the spreadsheet to record when the user presses and releases the arrow keys while navigating the spreadsheetIdeally, these events would be built into Excel alongside the native SheetActivate and SheetSelectionChange events, for example. Alas, they are not.
View 1 RepliesI 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:

View 2 RepliesI have created a simple program which uses a two tier structure of SQL Tables.At the top level, one record holds the date of the activities and linked to it using its primary key as a foreign key, three subordinate tables hold time stamped records.The issue I have been unable to solve is that before adding any of the lower level records for a given date, a newly added top level record must be saved to the database.Doing this manually is simple - but can I rely on my users to remember to do this before they start plugging in the lower level data?I thought not, so I am looking to save the top level automatically.I've failed miserably but I refuse to believe that it's not possible.
View 14 RepliesThis 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?)?
View 1 RepliesI have multiple level of For Each and in each level, i have a Linq that is the 'In' criteria as in:
[Code]....
It will go inside each for (because the value is not nothing), however, it will only loop (next) in the very inner 'For Each t In tFor'. After it is finish inner loops, the outer Fors' or Next will not execute... even thought there are more than one values in that 'In'... like 'sFor' or 'fFor'. i've noticed while debuging, while break at the for (for example 'sFor', before stepping in), i get the error message:
"Enumeration yielded no results" when i expand the result for that variable and it will not step into it. but if i do not expand the result, it will step in. It seem that some how, once an element is accessed for that 'In' collection, it breaks (meaning does not loop for the rest of the elements) the next for that collection is this a bug or am i missing something in Linq? BTW: i believe it has something to do with the SqlDataReader in the Linq. I'm working with IAsyncResult.
I am getting this error,here is my code.

Hi Friends,
Hope you all are doing fine.
Brief
I have been into learning VB 2010 Express for around 2 months now; I have been doing it primarily on weekends with a nice book by James Foxall. At the moment I am in Chapter 22 of 24. I have been able to make some sense on what he says but have
been able to follow him well. I plann to read the book in full twice before doing with it at the end of August 2011.
Today's Question
In one of my previous threads 'Becoming a Programmer' @Renee Culver encourages me to try to get to a level deeper. There are many other experienced programmers who have given adivce with equal 'punch' but I like to begin with @Renee Culver's
approach.
James Foxall guides me learning smoothly but I now at the 22nd chapter out of 24 feel a little uneasy. It feels like James tells I do. In Chapter 22 dealing with automation he guides me to work on Excel through VB. The reference to the Server is
set through the VB interface. I like to know how to get to a level deeper on this today. Instead of using the VB interface can't I establish reference purely through VB code? During this weekend I like to try accessing the Google start page
Combo to get search results for 'Novak Djokovic'. Could you help me?
Thank you Friends.

I've been developing a Vb.Net app lately, and I'm trying to make it as lightweight as possible (ie make the binaries as small as possible).I've done all the trivial stuff, but while browsing the binary with ILDasm, I noticed that it has a My namespace, with a lot of methods, although I don't use any of these in my program. It seems that there are default Get/Set methods for every form, and other methods.Or, can you show me a use case for the methods bundled by default in the binary? PS: I guess it's not going to make a huge difference in binary size: I'm just asking this out of curiosity; why would the compiler bundle useless methods in every binaries? Perhaps I'll learn that these methods are actually used somewhere under the hood.
PPS: Here's a minimal example:
Module Test
Sub Main()
End Sub
End Module

In my tic tac toe game I'd like there to be three different levels; easy, medium, and impossible. There are 2 forms; the difficulty level form and the main game form. When the game first starts the user will be prompted with the difficulty level form which contains 3 radio buttons; easy, medium, and impossible.
I've coded three different functions based on the difficulty level; easyMove(), medMove(), and impMove(). These have all been coded in the main game form. How could I run the respective function based on the radio button that was selected in the previous difficulty level form?
If it was on the same form it wouldn't be a problem but because it is on a different form I'm unsure of how to do this.
Using VB.net, I have a namespace which I'd like to rename for the future. However, I'd also like to keep the old obsolete namespace for a time to ensure backward-compatibility for our consumers for awhile. Is there a way in .NET to have two namespaces, one ordinary and one that merely is an alternative name for the other?

Is the DelegateCommand something that's part of WPF or is it just something created in the book?

View 1 RepliesI'm currently maintaining some old code for a company. As it would happen, the current app I'm modifying uses an older version of the in-house library (we'll call this Lib1.dll). They also have a new version of the library called Lib2.dll that improves upon the previous library in many ways.
Unfortunately, Lib2 is not backward compatible with Lib1. What's worse is that they both use the same namespace Product.Common.
How do I use Lib2 and Lib1 in the same project? Right now if I add references to both of them, VS tells me that certain classes are ambiguous (which makes sense, since they using the same namespace).
Basically, I need something like:
Imports Lib1:Product.Common.Class
I'm using VB.NET 1.1.
I've googled for creation of namespaces and found some very useful examples, what these examples didn't have is how do I compile and implement my created namespace on my system so I can include it from my various applications.So for example, if I create a namespace to load a config file from my application path and insert it to an array, Do i need to include the namespace on any project I use or is there a way to make it part of my environment?
