Pass A Delegate Into A Constructor Of An Abstract Class From A Descendant's Constructor?
Feb 15, 2010I have an abstract class which requires a delegate to function. I pass the delegate into the constructor. Now that I have a non default constructor I need to call the abstract class's constructors from the concrete class which means that I need to use MyBase.New(...). I have included a quick example below.
Public MustInherit Class BaseClass
Public Delegate Sub WorkMethod()
Private _Work As WorkMethod
[code]....
I have tried to do this but I keep getting the following error: "Implicit reference to object under construction is not valid when calling another constructor".Can I not do what I am trying to do above? I initially had the delegate setup in its own setter method. But then I am creating a deceptive API because it does require a point to a method to work properly.
Why Is Constructor Call Valid Only As The First Statement In An Instance Constructor
Nov 2, 2009what's the rationale behind this limitation: Constructor call is valid only as the first statement in an instance constructor i want to pass an argument to my constructor which validates this argument and calls mybase.new according to this argument but it doesn't let me

Public Class prob
Inherits System.ApplicationException
Public Sub New(ByVal problem As String, ByRef inner_exception As Exception)

Make Constructor Public And Allow Anybody To Create An Instance Of Class?
Apr 6, 2009I have a class inside a class.I need to expose the properties of the 2nd class to other classes, therefore it is public.However, I do not wish other classes to be able to create instances of this 2nd class, it should only be instantitated from its parent class.I thought I could resolve this issue by making the constructor of the 2nd class private, but this even prevents the parent class from instantiating its child class! How can I work around this, do I have to make the constructor public and allow anybody to create an instance of the class?

What's The Best Way For A C# Developer To Learn VB?
Mar 26, 2009I'm a C# programmer who needs to pick up some VB. The syntax differences are easy enough to figure out, but there are other things I'll need more of a tutorial on. For example, VB's "strict" mode in Visual Studio is something essential to me, but something I wouldn't have learned just by comparing language syntax. Any recommendations on how to pick up VB quickly, yet thoroughly? I can't stand to work through a 1000 page book introducing VB to novices.

Jul 19, 2011I updated a VB.NET application from Visual Studio 2008 to Visual Studio 2010 and made a few changes to it. Now it works fine on my development workstation but when the user tries to run it, it fails. The error detail is below. I've searched for System.InvalidOperationException and found several suggestions but none of them have helped. There isn't any static initialization code in the application. I changed the compilation to x86 instead of AnyCpu. None of these has helped. The project is compiled for .NET 3.5 and that hasn't changed. Both environments are Windows 7 64-bit.
Does anyone have a suggestion as to how I might determine what is causing this?

He asked me, how did i store the password in the database. Then i answered that i would encrypt it then store it in database.
Then he said after encryption, developer or admin still able to view the encrypted password. But he didn't want developer or admin to be able to view the encrypted password.
I thought of cookies, but if user clear their cookies file, everything will be gone.

From within the VS2010 developer the app runs as desired, capturing the data and displaying it on screen with console.writeline().When I compile and execute the code either from the debug bin version or the release bin version, the app only captures the first few bytes then closes. All the code is within the Module1 Sub Main. Is there a compile setting or other property that I need to adjust?

Display Selected Properties To The Developer?
Sep 15, 2010I have class containing 10 properties. It has constructor which accepts one string parameter say "Param1". This is actually a liabrary which will be exposed to the developer.
Now when developer writes a code for creating instance of this class and pass the param1, then depending on the value of param1 developer should be able to see limited properties.
If Param1 has value1 then developer should be able to see 4 properties.
if Param1 has value2 then developer should be able to see another 3 properties etc.

View 2 RepliesGet Unhandled Exception Information To Developer
Jan 26, 2010I am wondering how I would get the information on what errors get processed by the application.unhandledexception. I already handle the event and gather the information, but I am unsure how or what the best way to get that information to me (the developer).
So far I have vdialog that asks the user if he/she wants to send the error to me, kind of like when an error occurs in Windows XP and a dialog asks the user if they would like to send information about the error to microsoft. I am unsure what to do when the user clicks "Send".
I have thought about emailing to me, but I don't really want to put my email address as the from, because I might change it or its password in the future, thus breaking its usability.
I cannot yet do an anonymous FTP upload, because my website only allows one FTP user, and that is used only to update the website.
I also have thought about using the user's default email program, but that will not work in most cases of people who rely on web mail.

C# - Add Developer Documentation To Visual Studio Projects
Mar 16, 2012Basically, the question is: Where (and in which format) should I store textual developer documentation associated with my Visual Studio projects?
To elaborate: XML comments are great, but they don't cover all use cases. Sometimes, you'd like to describe the class architecture of the project at a high level, add usage notes to your library or just leave any other kind of message to future generations of developers working on this project.
I'd like to add these documents directly as files into the Visual Studio project, to ensure (a) that they are available to the developer without further searching and (b) they are version controlled (using the same svn/git/whatever repository as the source code).
Currently, I add a folder _Documentation to the project and use text files, but I'm not sure if this is the best solution. Visual Studio does not have an option for automatically word-wrapping text1, and manually fixing line breaks after each change is annoying. On the other hand, Word documents don't work well with version control, and TeX is too much of a hassle to set up and teach on each developer PC.
Is there a well-established best practice for this?
1 I know that there's Edit/Advanced/Word-Wrap, but this only affects the display, not the file itself.
