To quote from the ConQAT - Continuous Quality Assessment Toolkit website Long-lived software systems are subject to gradual quality decay if no counter measures are taken. Continuous quality control counters this decay through an orchestrated application of constructive and analytic quality assurance techniques. The Continuous Quality Assessment Toolkit ConQAT provides the tool-support required to enact continuous quality control in practice. It supports the rapid development of quality dashboards that integrate diverse quality analysis methods and tools.However before I spend lots of time looking at it, is it usefull for a VB.NET project?
I've created a Windows Form app in VB however I've decided the format is best suited to a Wizard style app. I've read a bit about creating wizards however I was hoping VS 2010 had a wizard to create wizards :) From what I've read there is a lot of coding to be done to create a simple wizard. Am I wrong ? Perhaps there is a third party app which generates the base wizard code?
I am getting following error when I am trying to use Convert.FromBase64String "The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or a non-white space character among the padding characters."
Dim payloadBytes = Convert.FromBase64String(payloadBase64)
Basically when my facebook registration form [URL]mphone field has a dash in it and encoded string is posted to other page and I am trying to decode it there which creates this error. Basically I am trying to extract data from Facebook Signed Request.
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?
I can quickly knock together soem code to xlate base 10 to/from bae 13, but I just wondered if something very easy already exists in VB.NET (or even somethign generic, with base N, but right now I am only looking at base 13)
I'm retrieving data from Excel and would like to keep my arrays 0 based but Excel returns 1 base. Is there a fairly simple way to return change the array from 1 to 0 base? Or do I just need to create a loop? Here's an example code right here:
I get this: Base class 'System.Windows.Forms.Panel' specified for class 'MenuButton' cannot be different from the base class 'System.Windows.Forms.UserControl' of one of its other partial types.
In old QBasic I could use the LOG function to get the base-10 log of a number. So I would have something like this...
sglFormula = 150 - (LOG(intTemp + 10) * 30)
... the LOG function would give me the log base-10 of a variable (intTemp) plus 10.How do I do this in VB.NET. Do I have to create my own log function and, if so, what would it look like?
I wonder if I can remove all added event handlers in all the child forms from the one base form in the Closing method. (VB.NET; .NET 2.0)Background: In a project I analyze a memory problem. I verified with the memory profile (see related question) and find out that some forms are not collected by the GC, probably because of the EventHandler non-removed references.
In the project all the forms inherits from the BaseForm. Now I search I way to remove in the OnClosed method foreach Control all the EventHandlers to/from the ChildForms.
When you create a webpage in ASP.net, the codebase inherits System.Web.UI.Page Now when I extend the page object to check for SessionExpired for example, I create a new class and inherit from system.web.ui.page, and overwrite some functions. The problem then is that on each page, I have to replace system.web.ui.page with my custompage class. Is there a way to extend a class by adding methods or modifying its methods directly (e.g. add the sessionExpired check to System.Web.UI.Page) ?I'm using .NET 2.0

I need to use these classes on the client system, but also need to be able to create these "tasks" through a management interface. Each class (Task) that inherits the base, could have its own properties that are unique to each class, but at the same time, share the same common base class properties. For example, the above shows a reboot task and a delete file task, the delete file task needs to know which file to delete, so has a property for that. But the reboot task does not need this property. So when the management application is creating these tasks, it shouldn't provide a text box for the file property for the reboot task. There may be more tasks created at a later date with completely different properties.
How would I go about providing the WinForms management application a way to enumerate each class into a ListView for example, and allowing the user to create these tasks and filling in the dynamic properties that each class would have? Desired functionality would be to create a task form that creates dynamic controls available for the properties as needed, depending on the public properties in each class, but at the same time have the base class properties available as well.
I am working on an Electronics convertor to convert inputs between the bases. My question is whether or not their is a way to declare that the input is in a certain base and not the default base 10.
Any best practices on how to deal with different versions of base classes.We have made significant changes to the base class but still have lots of code inheriting from the old base class. Could you recommend how we introduce new base class.We'd like all new code to use the new base class. But, we would like the option to have old code still inherit from old base class so we have time to switch and test old classes with new base class.
I have a class library that have a lot of classes, in every class I have "Inherits LINQDataContext". And In my xx.designer.vb file I have...
Public Sub New() MyBase.New(Global.My.MySettings.Default.DbConnectionString, mappingSource) OnCreated() End Sub
But I get a lot of "Class 'xxxxx' must declare a 'Sub New' because its base class 'LINQDataContext' has more than one accessible 'Sub New' that can be called with no arguments." errors
I have a base class that contains a fairly large number of parameters in it's New constructor. I have 7 subclasses that inherit the Super base class. My question/issue is, all of the subclasses use the same values for most of the parameters in the New constructor of the base class and these subclasses can be called one after the other. I would like to populate the common values for the superclass and then use those for each of the subclasses, but I can't come up with a good way to do this. If I could figure out how to do this, I wouldn't have to pass all of those parameters in the MyBase.New call for each subclass. I'll try to illustrate with some code .
In the inherited class I use the base constructor, but I can't use the class's members calling this base constructor. In this example I have a PicturedLabel that knows its own color and has an image. A TypedLabel : PictureLabel knows its type but uses the base color.
The (base) image that uses TypedLabel should be colored with the (base)color, however, I can't obtain this color

REF: http:[url].....The above reference is where I got the code below.This code adds buttons to Form1. When a button is clicked a messagebox appears stating what button was clicked. I want to have the ClickHandler fill a RichTextBox on Form1 (I added a RTB to Form1). My problem is I can't do a Dim xForm As New Form1 to fill the RTB from the ButtonArray Class. I can place my file's text in a MessageBox so I know the code I added is correct. I also tried placing a Property method on Form1 and using a Accessor to fill the RTB, however it also requires Dim xForm As New Form1. How can I get my data from files to the RichTextBox on Form1 from the ClickHandler in the ButtonArray Class? See ButtonArray Class Below.
The program below trhows an error in the line "mTable2 = mTable.Copy". The error is: "Unable to cast object of type 'System.Data.DataTable' to type InherintanceQuestion.InheritedTable". This is because mTables is an instance of the InheritedTable class which inherits a DataTable and mTable is a DataTable. So, is there any way I can create the mTable2 to the mTable.copy to the mTable.

I, will just explain a few areas of this to ease the process of understanding it:
1-The conversion Subs are to be used for values such as A7 in Hexadecimal
2-The Err Boolean will hopefully be used to link back to the top in the event of an error
3-Apollogies for the abreviated variable names, it simplifies things in my mind but winds my fellow students and teacher up no end.
This code is not fully functional yet, however I believe it should give an answer for my test value of 800 Base 10 to Base 8 (1440), however when the program runs in debug mode I can enter the three inputs but then it leaves two lines and gives an unresponsive flashing cursor.
