If I have a user control with some control on it like
a TextBox's and buttons does calling the default Dispose
on my user control cause those inner controls to also
be disposed ? Or must I do my own disposing for
all those too??
thanks,
JIM

I used to think that all objects that implement
IDisposable should be disposed. But I found 80% of the
classes implement IDisposable.
But when I looked into the samples, most objects are not
disposed. Generally, they're Gdi objects, form controls,
most components, etc.
So why? How can I decide to dispose or not?

I have a form on which user controls are placed at runtime. When a control
is added to the form a handler is added for an event that a high-level
object raises, which must be handled by the new control. When I close the
form I am expecting that the control ceases to be.
However, if my object raises the event after the form has been closed, I
find that there is still a user control object that handles it. Clearly the
user control has not...

Ok, I'm trying to dispose of every object that I create that has a dispose
method based on advice from this newsgroup. However, I'm not sure how to
dispose of the following object that was created inside a method call.
dim myvar as new object1
object1.dosomethingmethod(new object2)
Note that object 2 has a dispose method but how do I dispose of it unless I
do the following:

I have several functions that require doing a New on a local object. If the
object is local to a sub or function, do I need to dispose of it, or will
it just go away like any other local variable?

Banging my head against the wall trying to figure this out. I have a
'sometimes' hang while disposing a form which contains an ActiveX
control (Flash.ocx version 7). The form's Dispose() method generated by
the form designer
protected override void Dispose( bool disposing )
{
if( disposing )
{
if(components != null)

Hey guys,
I'm having some weird issues when calling Dispose on one of the controls in
a user control from an asycn or sync method. When called form an async
method Dispose makes a call to SelectNextControl but not when called from a
sync method. I'm trying to figure out why that is so.
Does anyone know under what conditions Dispose will call SelectNextControl?
I have a breakpoint set on the user controls OnValidated method and when...

Hi,
If I add programatically a Panel to a control, and a Label add to that
Panel. Then when I Dispose the Panel do I have to Dispose the Label
also, or does the Panel take care of that ? And if it is do I gain time
doing it myself or not ?
I ask this because if I for example put panels or labels on Mappoint
ActiveX control, and I don't dispose them myself it take a lot of time
to destroy the activeX control. But maybe this is not the...

In the main program I check to see if a certain form has been disposed.
Does it make sense in that form's FormClosed event to do:
Me.Dispose to make sure it is disposed the next time I check.
Or is that automatic?
Thanks

I have a list box on my form, but I need to databind it to a data table that
is a private member of the form's class... so I basically have
Public Class MyForm
priate m_MyTable as new datatable
End Class
now where would I properly dispose of this? In the finalize method? I am
loading the data for the table in a subroutine that is executed at form
load, of course all the commands tied to it are wrapped in using blocks, but

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
