Holding a reference

[Dagoberto Aceves]

I'm having trouble with references. Specificly i want to maintain a
reference to a string. So that after I pass it to the constructor, other
methods can have at it. I can do this is C/C++, but I can't seem to make
it work in VB.
In the constructor I have

Me.Value = value ' where value was pass ByRef, and
' Me.Value was declared global As String.

when i return to where the func was called, the string put in is not
there.

It doesn't look like you are trying to change the value of the external
string. All it seems you are doing is setting the initial value of the
Value property of the class instance that your code is wrapped inside of.
When you return to your function, your original string should still be
there, as nothing has attempted to change it.

Please show us the code that is calling the code below and show the whole
constructor code as well.

The function calling the new form goes like this.

...
Dim getResult As String
f = New SingleItemListEdit(type, True, getResult)

...

' In constructor

Public Sub New(ByVal thisList As List_Editor, ByVal setDialog As
Boolean, ByRef value As String)
...
Me.value = value ' A way to communicate back to the calling form

' In global
Public value As String

' Other function use the Me.value

Dagoberto,

You are passing a pointer to a pointer which points to Nothing, what is the
sense of that.
