Killing a thread is a bad idea in almost all cases. It can destabilise the entire process.

No I dont think so.

AFAIK the managed threads are virtual, i.e. they are not even guaranteed to correspond to
a physical (i.e. a Windows kernel) thread.

This is somewhat illustrated by the fact that managed threads have a ManagedThreadId property,
whose value does not correspond to the kernel's thread IDs; and it has a name, for which
the kernel has no equivalent member at all.

In my experience, there still is a 1-to-1 correspondence between a managed thread and a
kernel thread, but I havent found any way to map them, other than having each managed thread
call some native code to get its own kernel thread ID that is.

Hope this clarifies things a bit.

Do you want to include Dialog box which are created in VC++ ? Is it anything like MFC COM (ActiveX) controls ?

No,
May it be created in C# and generated by the wizard as C# Form is.
Hope this clarifies.
Thanks.

using settings

Hi,
I created a settings file using Visual Studio 2005. The class for the settings file is generated as internal by VS. I need to reach it from another namespace so I want to make it public not internal. Is it good to make a settings file public or does it have any bad effects?

Re: using settings

As it is internal, it's available in the entire assembly, even from a different namespace.

If you need to use the information in another project in the solution, you get a mutual dependency if you access the settings directly. Instead you should send the needed information when calling the method, or creating the object instance, that needs it.

I believe the cs file in question is machine generated so its no point making changes to that. Why dont you write your own class which can traverse the settings file using the XML namespace.

Hello,

In your CancelButton code (Click event handler), you could set the DialogResult property of the Form to DialogResult.Cancel.
So if the user Closes the Form over the 'X', the Default would be DialogResult.None.

private void CancelButton_Click(object sender, System.EventArgs e)
{
    this.DialogResult = DialogResult.Cancel;
    this.Close();
}

protected override void OnClosing(CancelEventArgs e)
{
    if(this.DialogResult == DialogResult.None)
    {
        //Comes from X
    }
    else if(this.DialogResult == DialogResult.Cancel)
    {
        //Comes from CancelButton
    }

    base.OnClosing (e);
}

Hope it helps!

All the best,

Martin

OnClosing is th protected virtual method which fires the Closing event in the base Class (System.Windows.Forms.Form).
As you have your Form derived from Forms.Form, you don't have to handle the Event itselfe, you just can override the method.
Like I did!

Hello,

Now you also want DialogResult.Cancel set, if the user closes with 'X'.
Just set it in the Closing or Closed event.

All the best,

Hi Martin,

I dont think it will work your way. Windows already sets DialogResult to Cancel on
hitting the Close box.

This is why: Microsoft intends the Close Button to be identical to a Cancel
action; closing the dialog or pressing Cancel button both indicate "hey, I dont want this,
I am not interested". It is part of the overall GUI conventions that MS came up with.

And, we have had a difference of opinion on this before: one should not go against
such conventions.

Smile | :)

I did, with VS2003 .Net1.1!

IIRC it was about changing the behavior of a group of radio buttons; my point was and is
if it looks like standard controls, it should behave like them too.

That's also what I think, but I think the point was to modify the behavior in combination with the style.
