How To Call The Constructor With Parameters

Jun 1, 2010

I am stuck with a problem about generic classes. I am confused how I call the constructor with parameters. [Code] I get error in the starred area of the DBLayer Object. What might be the possible reason? what can I do to fix it? I even want to add New(byval someval as datatype) in IDBObject interface for overloading construction. but it also gives an error? how can i do it? [Code]

Why Is Constructor Call Valid Only As The First Statement In An Instance Constructor

Nov 2, 2009

what'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

example:

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

[code]....

Inherit A Sub New (Constructor) With Parameters?

Apr 25, 2009

In the code below I recieve the compile error "Error Too many arguments to 'Public Sub New()'" on the "Dim TestChild As ChildClass = New ChildClass("c")". I do not recieve it on "TestChild.Method1()" even though they are both on the base class I am inheriting from.

Public Class BaseClass
Public ReadOnly Text As String
Public Sub New(ByVal SetText As String)[code].....

As suggested below but I do not have to do that for Method 1 or other inherited methods and I am looking for the cleanest code possible. This may be a limitation in the system with inheriting parameterized New statements but I can not find it documented anywhere. If it is required then I would like to see the documentation.

.Net OOP Superclass Base.net And Constructor Parameters?

Mar 13, 2009

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 .

Java - Multiple Argument Constructor Cannot Call Each Other Itself

Mar 29, 2012

I have recently found out that no argument constructor and multiple argument constructor cannnot call each other in turns. What is the underlying reason of this limitation? Some might say that constructors are where resources are initialised. So they must not be called recursively. I want to know if this is the only reason or not. Functions/methods/procedures can be called recursively.

VS 2010 - Call Valid Only As First Statement In Instance Constructor

Jul 19, 2011

I'm trying to create an array to be handled during my code. I want to create it as soon as I open the program so I've placed it in my bit of constructor code. This code was working fine before I tried to initialize a new array in there but when I place that in I get the above error message. This occurs whether I put the new array bit of code first in my constructor class or not.

Pass A Delegate Into A Constructor Of An Abstract Class From A Descendant's Constructor?

Feb 15, 2010

I 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.

C++ - Call An *.exe-file Through A *.dll-file And Submit Parameters?

May 21, 2012

I'm trying to start an *.exe-file with the help of a *.dll-file instead of calling the *.exe-file directly. It will be used for a program that is able to start *.dll-files, but not *.exe-files.In this case: The browser.exe is written in vb.NET and the browser.dll file in C++ (I could not find any dll snippet for vb.NET).The code-snippet for the browser.dll (MFC-DLL) that has been generated by VS2008 and has been modified a little bit by me looks as follows:

[...]
CBrowserStartApp::CBrowserStartApp()
{
system("start .\browser.exe");

[code]....

I can compile it without errors. there's an error message if I start the dll with Rundll32.exe and add any parameter. Then the program starts, but the error message is still there. It says something as "Error in browser.dll. Missing Content v" if I start it with "Rundll32.exe browser.dll v". If I leave out the parameter "v", nothing happens. Neither an error appears nor the actual application.

I have is as follows: Usually I start the *.exe-File with parameters such as a URL [URL]. How can I add such URLs to the *.dll-file? The same trick as for usual program (e.g., args = Environment.GetCommandLineArgs())? How can I access them and take them forward to the actual *.exe-file then?

C# - Search For Names In The Database That Matches Whole Parameters Or Any Part Of Parameters

May 13, 2011

I'm writing a query to select all records that has any part of parameter. I have one table called Employees. Some people have name like this: John David Clark If the parameter is

[Code]....

I should be able to get result back as long as there's a match in the parameters. If I use Function Contains (q.FirstName & " " & q.LastName).Contains(employeeName), I will not get any result back if employeeName is "John Clark" Function Contains looks only for next words from left to right. It doesn't match a single word at a time. So that's why I used this in the Linq to SQL:

Static Constructor In .Net?

Feb 9, 2010

I am rewriting a C# class in VB. The C# class has a static constructor in it:

static Class()
{
...
}

which, through the Call Stack, I found is called by the main window's InitializeComponent() method.Everywhere I've looked has told me that the corresponding static constructor in VB is just:Shared Sub New()

but this method is never invoked. Am I creating my VB static constructor right? Is it likely something else that has nothing to do with my static constructor?
