2008 - Error: WithEvents Variable 'CompanyName' Conflicts With Property
Feb 22, 2009I've got a TEXTBOX called CompanyName. And I've got a warning in the error tab that says:
WithEvents variable 'CompanyName' conflicts with property 'CompanyName' in the base class 'Control' and should be declared 'Shadows'.
Is CompanyName some kind of reserved keyword? I'm getting the same error for a textbox called Location. Can I ignore these warnings or must I rename my textboxes. My problem is the textboxes are named to match columns in a DB TABLE to allow me to do some auto-binding logic.

Error : Handles Clause Requires A WithEvents Variable Defined In The Containing Type Of One Of Its Base Types
Mar 25, 2010I am in the processing of moving an app from VB to C# but some of the classes I will just be moving to VB dlls to access from the main C# app. In doing this I am trying to get the VB dlls to utilize the main C# class lib. In this C# lib I have an abstract clase called base process, it sets up a background worker and handles all the progress tracking, errors, and even reports an ETA. To use this in a derived class in C# you would just do this...
public class SomeLongProcess : Common.Multithreading.BaseProcess
{
public void start()

The problem is that if I do the equivelant in VB I get an error "Handles clause requires a WithEvents variable defined in the containing type of one of its base types". Well I can't do a WithEvents in the base class because it is C# so..

For Each Variable Acting Like A Local Var?
Apr 21, 2011I stumbled upon something i don't quite see the logic of. Let's ork with following piece of code:
For Each ds As DerivedScale In List
If ds.ScaleID = scaleId Then
ds.ScaleID = ds.ScaleID + scaleStep
[Code].....
This piece is written for 2 records to change place and change the sequence number (scaleid). The arrow indicates where the issue occurs. The item "ds" is replaced by the object 1 indexnumber higher/lower. This does however not effect that object in the List. So when i check, item ds isn't set.
However, when i look at ds.ScaleId = ds.ScaleID + scaleStep, this is reflected in the List.
So what I am wondering is: is "ds" acting like a local variable here, and can i only make changes to it's properties?
Global Vs Local Variable
Mar 22, 2010I'm writing a subneting calculator in VB.NET.I'm using the IDE SharpDevelop.Well my problem is I'm using a function to do some calculations and then to figure out the class of the IP addresses.Well I pass a variable from the subroutine, that is accessed when a button is clicked, to the function then the variable is passed back to the subroutine and then the variable is passed again to another function but when it reaches this second function it doesn't retain the value it was given in the first function.I'm not sure if I'm just passing the variable wrong or if this is how it works.I know I can make this work probably by using global variables but I'm not sure if this is proper. So my ultimate question is what is the difference between local and global variables besides just scope and should I try and use one more than the other.
View 4 RepliesInstantiate Local Variable By Value?
Jan 7, 2010I sort of understand why this is happening, but not entirely. I have a base class with a Shared (Static) variable, declared like so:
Public Shared myVar As New MyObject(arg1, arg2)
In a method of a derived class, I set a local variable like so:
Dim myLocalVar As MyObject = myVar
Now when I do something like myLocalVar.Property1 += value, the value in Property1 persists to the next call of that method! I suppose I get why it would be happening; myVar is being set by reference instead of by value, but I've never encountered anything like this before. Is there any way (other than my workaround which is to just create a new object using the property values of myVar) to create myLocalVar by value?

View 1 RepliesHow To Add Event Handler To Local Variable
Apr 25, 2012I have a form in VB.NET that is used as a dialog in a mainform. Its instances are always locally defined, there's no field for it. When the user clicks the OK button in the dialog, it will fire an event with exactly one argument, an instance of one of my classes. Since it is always a local variable, how can I add an event handler for that event?
Code for the event, a field in MyDialog:
public Event ObjectCreated(ByRef newMyObject as MyObject)
Code for the main form to call dialog : (never mind the syntax)
Dim dialog As New MyDialog()
dialog.ShowDialog(Me)
AddHandler ObjectCreated, (what do I put here?) //Or how do I add a handler?

.net - Declare A Local Variable Whenever Access A Property?
May 7, 2011say i have an auto property Public Property P As Integer and everytime I want to read this variable P in a function, i will declare a local variable as such: dim _p = P then read _p instead of P. I'm wondering does it make sense at all? will it actually make things slower (which of course isn't my intention).Btw if we change the question to Public Property P As Object is there any change in the answer?

Should A Local Variable Call Dispose Method And Set To Nothing?
Oct 14, 2009I have 2 question, hope somebody give me an explanation: 1. Should a local variable call dispose method and set to nothing? 2.
