Changing Object Reference In Constructor Parameter?

Oct 30, 2011

I'm trying to change the reference of a variable passed from one form to another in the constructor of the recieveing form but after I've changed it the original reference still remains in the source form. Why is this and can I force it to accept the new reference?

WithEvents And Changing Object Reference

May 3, 2011

So I wanted everyone's opinion on this and what you think of this. Using the WithEvents modifier makes life very easy in VB.Net (srsly, I love it), and I was exploring some of its limitations and noticed you can do something along the lines of this:

C# - Accessing Constructor Parameter ByRef?

Nov 22, 2010

I want to make a generic EventArgs sub class that has a write-only property which, when updated by the code that is handling the event, will also update the byref parameter of the constructor of the class.

The code I have so far doesn't work. How do I get the property "Item" to update the "item" constructor parameter so I can retrieve the value that was set?

public class EventArgsSet<T> : EventArgs
{
public EventArgsSet(ref T item)
{

Error: Reference To A Non-shared Member | Constructor; Pass Variable

Mar 13, 2010

I've been trying implement Constructor method in passing variable between two forms.Just a rough user interface guide - issue Invoice. User would type in all the Customer Name, Document Number. Once he reached Item Details, a Child Form would pop-up for the User to select/search the Invoice's Item; Once selected, the selected item would showed in the primary Form.

What I had tried is, the Constructor method worked perfectly when it is self-contain in a new project, yet to be implement in my application.But when I implemented, there is an error: Reference to a non-shared member requires an object reference.

Error - Reference To A Non-shared Member Requires An Object Reference

Dec 7, 2010

I am opening frmB (variable for FormB - the actual form) from frmA. From btn1 I open frmB like this:

frmB = New FormB()
frmB.Show()

From btn2 (frmB is already open) I bring frmB to the front from behind frmA:

FormB.Show()
FormB.BringToFront().

No problem so far. Now I need to pass an arg to frmB. This is where I am having the problem.

from btn1 (in frmA) I do this:

frmB = New FormB(myArg) '--pass myArg to constructor of FormB -- no problem here
frmB.Show()

then from btn2 -- this is where I have the problem

FormB.Show()
FormB.BringToFront()

I tried placing myArg in FormB.Show(myArg) but that did not fix the problem. What is the correct way to pass myArg to FormB (frmB) in this scenario? Do I need to share FormB or frmB? How do I do this? "frmB" is frmA level variable.
