Check form loaded and hidden

SRSDS — Wed, 17 Jul 2019 18:52:42 GMT

Hi,

I am loading a form which is populated with several pictures and controls.

There is a small delay in it's loading so I would like to hide it and make it visible again.

How do I check if it's loaded?

            If SOMETHING Then
                FormShapes.Show()
            Else
                Application.ShowModalDialog(Application.MainWindow.Handle, FormShapes, False)
            End If

Hi,

You can use a static (Shared) field to store the form instance that you initialize only once per session if it's null (Nothing).

        static Dialog formShapes = null;

        public static void SomeMethod()
        {
            var doc = Application.DocumentManager.MdiActiveDocument;
            if (formShapes == null)
                formShapes = new Dialog(); // or whatever the form class name

            Application.ShowModalDialog(doc.Window.Handle, formShapes, false);
            [...]
        }
