Creating A Corporate .Net Namespace Framework From Scratch?
Apr 21, 2009
We are migrating our applications to VB.Net 2008 from Classic VB and I need to create a base namespace and business layer. My method of approach is going to be to visit our top BA and identify the common areas of our (Fixed Income) company and try to form a decent inheritence model with as much of the code in generics as possible. What's everyone's experience of doing this and also as a second part of the question, we are looking at incorporating Web Focus into the OLAP side, how would this affect the design of the corporate namespace and it's derivatives?

I want to build a simple chat app where people can go a url, type in a name and a message and click submit and it will basically show that message to everyone that is current connected.Firstly i would like to state i've had zero experience in sockets programming and the like. I'm simply a web 2.0 person building websites with css/html/js/ajax and backend i have asp.net on vb and sql server for database.So basically coming from an ajax background, i was wondering why do we even need to download any additional stuff to do web sockets? I mean in ajax i can simply create a asd.aspx file and use Response.Write(text) (text based on the input which are available through dissecting the url) and voila, the server side is done, all that's left is just to create new XMLHttpRequest and stuff in the client side.
So ok I'm not worried about the client side part of Web Sockets. but the server side part of web sockets is just difficult. so in the client side i have this: ws://localhost:8080/websocket. Is it true that it will work if is also an .aspx file as such: ws://localhost:8080/websocket.aspx ?I'm wondering so how do i continue from here? in Ajax i will supply parameters from client in the url as such: page.aspx?a=1&b=2 and do output in the server using Response.Write it's all clear but how do we do it in web sockets?

The Vb.Net application creates a bitmap from scratch and either converts to a tiff or sends it to a printer. In both cases, the quality of the image (in this case the font) is not good at all. The sample code listed below creates the graphics object that I use to write to the image.
Dim gr2 As Graphics = Graphics.FromImage(New Bitmap(800, 1000), Imaging.PixelFormat.Format32bppPArgb))

When you develop a class library that will be used by others, are there any guidelines on how you decide what namespace to put it under? I often find third party classes just use the company name as the root namespace but I was also wondering if it is frowned upon (or even possible) to add one of your own classes to an existing framework namespace.

We've just re-targeted a VB.NET project from .Net 2.0 to 3.5.Various framework types are now missing from our project. Wherever the type is referenced using a fully qualified namespace it's missing. If the relevant namespace is imported for the type; it's found.For example,this doesn't find the type Object, with compiler error "System.Object is not defined.":

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?

As my Christmas week side-project I thought I'd knock up a quick console app that I can run from the windows Start-up folder.
The application is going to delete some unwanted Global Corporate Desktop Icons (I like to run a clean desktop - is this common?) and Reset the Windows 7 Theme to my lovely Visual Studio 2010 graphics.
I have read the reasons why this shouldn't be done pro grammatically for the user but I feel this case is different as every morning I am manually deleting the icons and resetting the theme (policy is not stopping this - just reapplying it every morning) so I though this little side project could save me time in the long term.
I am deleting the Icons OK but I am struggling to set my theme ala:
Dim key As RegistryKey = My.Computer.Registry.CurrentUser.OpenSubKey("SoftwareMicrosoftWindowsCurrentVersionThemes", True)
[Code]....
This is setting the registry key correctly but not applying it. Ultimately I may try a simple Wallpaper Set but I would like to use the theme if possible!

1) DynamicPDF.Test.ClassA
2) DynamicPDF.Test.Report.ClassB
using the VB.NET i was generated the Tlb file.

I have the following two tables defined...
CREATE TABLE [LogLevel] (
[Id] int primary key

After creating a fresh endity model, I add the two tables above. When I try to build I get the following errors...
Type argument 'Inxsol.CommandPlan.Data.Model.Log.LogLevel' does not satisfy the 'Class' constraint for type parameter 'TEntity'.
Value of type 'System.Data.Objects.DataClasses.EntityReference(Of Inxsol.CommandPlan.Data.Model.LogLevel)' cannot be converted to 'System.Data.Objects.DataClasses.EntityReference(Of Inxsol.CommandPlan.Data.Model.Log.LogLevel)'.

I 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:

I want to know how I could create a bitmap from scratch with no images to start with.(I would say need. but than you would think this was for some sort of school project and it's not.)Basically, what I have is an image which is perfectly square in shape and has a black border with a black x going through it, what is not black is white. What I'm looking to know is how to take that small image (50x50 pixels) and make an image based upon those by placing them in X Rows of X amount. I'll make a couple example to show what I mean.(X's represent the 50x50 image.

i would like for my first project to be a CPU stress testing program (kind of like Core Damage or Intel Burn Test).I have no problem designing the form, but how and where should I start? I've done some searching, but haven't really found much. I think the reason for that is because nobody is really going to just give out source code for anything (which is completely understandable).
The main thing I would like to understand is what exactly makes the CPU work at 100%? And how could I design it to where it automatically determines the amount of cores/threads the CPU has, and utilize them 100% without having to open up one instance for each? Or is that jumping too far ahead?
EDIT > I know that I'll need to create some kind of loop for the CPU to process over and over until closed. I was thinking something along the lines of calculating Pi to 32 million digits or something like that.
> Another goal is to have some sort of error checking capability. I am an overclocker, and I would like to have this ability with this program. For example, it I make it to calculate Pi, then I would like for it to tell me if there were any errors in the digits it produced.

This 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?)?

I'm currently starting a new job in which I will be working on some coding in the future and need some advice on some good places to start so I can learn this correctly. Essentially we need to bring VB4 code over to the new VB.net language and I will be tasked with this. The project consists of a large battery of tests for psychiatric patients consisting of mostly multiple choice questions presented one at a time - since VB4 isn't very compatible, I think I will create a new battery from scratch while using the old code as a reference point.
I started creating the code this weekend for fun and am really enjoying it. However, a huge problem has been the abandonment of control arrays in the new language... by the time I got to creating my first questionnaire I'm stumped and can't follow the old code. Clearly I'm not ready to tackle such a large project with no experience and need to start from scratch; who would have thought .
The reason why I'm here is not to ask you to help me with my work. What I'm wondering is if any of you have any cool advice of great places to start learning the language (books, websites, etc). The amount of literature is very overwhelming so I thought I would ask some people with experience for tips. If any of you have stumbled across learning material with emphasis on coding that would be useful in the design of questionnaires or multiple choice exams, it would be particularly useful.
So far my starting place is Visual Basic 2010 Step by Step with Michael Halvorson, it seems good at a glance in the sense that it couples theory with practice but I'm already sure I'll need a little more.

I have a solution that I wish to upgrade from Vb.net framework 1.1 to framework 4.0. The solution consists of a number of projects, all but one of which compile to dll's. The master project compiles to a executable which provides a menuing system which dynamically loads the dll's and connects to entry points.
The projects contain normal classes, numbers of forms and also controls, which are either usercontrols or are inherited extensions of standard windows controls.There are a number of third party components (eg reporting and grid controls from Component One, Ribbon control from DevExpress etc).

I work for a small company and we are planning to build our own framework using .net . For example if a dropdown is placed in the form and set the custom property to Users, then the users list from db from has to populate. The developer will drag and drop the custom control and set the connection string in config file. Other things are to be managed by the framework.
