[gui] closing or hiding a parent form

[Thorsten Ottosen]

Dear all,

Is it possible to close or hide a parent form?

In particular, is it possible to do from the child form itself?

Thanks

Hi,

Pass the parent form as part of the constructor of the child form, then as
needed call Hide()

For some reason this does not work as I expect.

hi

post the code you are using

Can't do that; sorry.

But I can describe the situation a little better (something I should have
done the first time :-()

We start with the parent form:

using(frmMedarbejderListe f = new frmMedarbejderListe(
m_erMedarbejdersErindringer ) )
{
f.Open( this );
}

Then in the child form I do

public override void Open( Form parent )
{
frmMedarbejderSoeg fader = parent as frmMedarbejderSoeg;
fader.Hide(); // #2
Debug.Assert( fader.Visible == false );

base.Open( parent ); // #2
}

base.Open(parent) does various stuff, but ends up calling this.ShowDialog();

Now, the funny this is that if reorder the lines marked #1 and #2, the
parent form is not
hidden...when I look behind the child window, the parent form is still
there;

If I don't reorder the two lines, the parent form is hidden, but the screen
flickers
a bit before the child window appears proproly on the screen.

Neither behavior is particular good.
