Create A Method SetValues - Call Multiple Constructors?
Dec 29, 2011
I'm a c# developer and have not enought experience in VB.NET.the scenario:
Namespace Presenters
Public Class BaseFooPresenter
assuming the public default parameterless constructor[code]....
I can create a method SetValues( ... parameters ... ) and call it from the two constructors but does someone knwos a workaround to avoid this error?, why the compiler do not validate the possibility to call the base constructor before the overloaded constructor?how to justify logically the fact that it's not possible to call the base class constructor and another class level constructor from one class level constructor at the same time?

(New clsViewIllus).View(MyIBaseView, enumViewSolveTypes.View, Me, , True)
... in VB? Basically too lazy to do this:
Dim vi As New clsViewIllus
vi.View(MyIBaseView, enumViewSolveTypes.View, Me, , True)

I would like to know if you can have multiple constructors in a VB.NET class? Like in java, you can have multiple constructors as long as they have different parameters, is that possible here?

Iam wanting touse sendinput in a dos or background type app (can be a regular app thats hidden) that emulates mouse clicks and sends mouse moves to another multimouse application. an project that im working on for my school i work at and i need to send the input to it. The overview of the project is i need to have this code be in a service that runs in the background that when a person does a gesture with my kinect code then it clicks the left mouse or sythesis it with sendinput (need mouse up and down sent for this to work). The end programs that receive input are: a program written in the multipoint sdk and mouse mischief. I though about using the default usb mouse driver as an emulated mouse driver to handle the part about creating a usb mouse device that works
since most newer computers are using usb.

I have a large problem with inheritance in vb.net. The problem is the following:
I have 2 forms => frmBase and frmChild
In frmBase i want to create a method Called StartWorking() and i want frmChild to inherit this method.
But here is the tricky thing: when frmChild.StartWorking is called i would like the following => without calling MyBase.StartWorking()
I want frmBase.StartWorking() to be executed first and after a test in frmBase.StartWorking if blnValue is true then frmChild.StartWorking has to be activated. if blnValue is false that frmChild.StartWorking cannot be activated.

I have a class that runs as a thread. While the thread is running, I want to call a method in that thread. I do this commonly where a thread calls a method in the GUI with a delegate. But I'm confused how to do this when the called thread is not the GUI and there are no parameters passed to the called method.

may I just ask a seemingly simple question for which I can't find any solution throughout all the VB.NET documentation: I have to call a (non-static) method of another object (instance!) based upon the name of the method (given as a string).

I have a method written in VB.NET. It looks like this:
Shared Sub SomeMethod(ByVal Id As Guid,
Optional ByVal str1 As String = "foo",
Optional ByVal str2 As String = "")
I want to call this method from C# 3.0 and I want it to use its default arguments. I tried passing System.Reflection.Missing.Value, but I cannot cast it as String. Is there any way to do that?

I have a method called ADD in a class that connects to a database. The database class name is XDB. I also have an object named XXX in it's own separate class with properties.One of the instructions for the Button named ADD click event is:
'Call Add method passing in the XXX object
So this is how I coded:
'declare a variable X as an object instance of XXX
Dim X As New XXX[code].....
I know it's wrong since it doesn't add the XXX and the form doesn't close but I don't know what I'm doing wrong.

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.
Imports System.IO
Imports System.Text
Imports System.Collections.CollectionBase[code].....

I have a asp.net web application with jquery controls. I have a datagrid that will display data from a database table and created a WCF Service to access the db and return the data. I want to be able to call the WCF service from this application which is on a different server and have the xml data returned, converted to json format to be used in the datagrid which is a jquery widget. I have tested the web service and it works fine. Should I call the web service from the javascript function within the xml or create a .net method behind that calls the service and then does the conversion? From these how would I get started?
