using the show command

Hello!

When I have only one window how can the window form be displayed
when I don't have a show method. As in the example below with the Form class
FrmContainer

If I have an MDI child I must explicitly use the Show method for the MDI
child.

Can somebody explain that!
Is it possible to write some code which confirm that the show method is
called.
static void Main()
{
Application.Ena bleVisualStyles ();
Application.Set CompatibleTextR enderingDefault (false);
Application.Run (new FrmContainer()) ;
}

public FrmContainer()
{
InitializeCompo nent();
}

I believe someone already answered this same question in a different
thread.

Hello!

The answer in another thread said the following.

"Application.Ru n calls Show
do this, redefine the Show method in your form and put a breakpoint
there, take a look in the call stack and you will see the call"
I redefined this Show in the following way
public new void Show()
{
...
}

I put a breakpoint on this redefined Show but there was no call to this
method

I admit, the term "redefine" is ambiguous. The person who wrote that to
you could have been more careful with his words. But what made you think
that hiding the base class Show() would accomplish what you wanted?

The short answer is that Show() is called implicitly when
Application.Run () is called. More generally, when you are writing new
versions of a virtual method, you practically always want to "override"
rather than "new".
