Question

(I’m trying to create my own custom MSGBOX from wpf…)
How do I show another WPF Window without having this kind of code

WpfWindow w = new WpfWindow();
w.SetBox("hellow world");
w.ShowDialog();

however i kind of found a way to lessen the CODE but i still need to create another instance (which is a waste of resources)

new WpfWindow().ShowBox("hellow world");

the ShowBox(string msg) Method:

public bool? ShowBox()
{
    SetBox(msg);
    return w.ShowDialog();
}

I want to get rid of that “new” code snippet (if that’s what you call it)

so…in conclusion…I wanted to know how to make a Static WPF Window…

Answer 1

You can simply wrap your code in a static method in your class:

class WpfWindow {

  public static bool? Show(String message) {
    var window = new WpfWindow();
    window.SetBox(message);
    return window.ShowDialog();
  }

}

You then call it like this:

var result = WpfWindow.Show("Hello world");

You may object to the fact that a new instance of the window is created on each call but I don’t think you can avoid that. You are using ShowDialog to show a modal dialog and for this dialog to return control to your code it has to be closed. A closed window cannot be reopened and you have to create a new instance each time. It shouldn’t be a problem though.
