Question

I’ve been working at this on and off for a while but essentially I have a class that I call to display message boxes.

I’m trying to get my message boxes to be modal, which is easily done if you specify the form to be modal to.

So my form is declared like this

public partial class MainForm : Form

and it is instantiated like this

var mainForm = new MainForm();

So I have a class that contains methods which open message boxes like this

MainForm.ActiveForm.Invoke(new MethodInvoker(delegate
{
    MessageBox.Show(MainForm.ActiveForm, message, title, buttons, icon);
}));

This works fine, but active form only works when the form is active…..

Anyways is there an easy way around this?

Answer 1

I have a solution that works fairly well, but I’m not sure if there is a more elegant solution.

So in MainForm.cs I have

public static Form mainWindow { get; private set; }

Then in the OnLoad method

Focus();
BringToFront();
mainWindow = MainForm.ActiveForm;

Then in my message box method:

MainForm.mainWindow.Invoke(new MethodInvoker(delegate
{
    MainForm.mainWindow.BringToFront();
    MessageBox.Show(MainForm.mainWindow, message, title, MessageBoxButtons.OK, icon);
}));

Am I missing something here? Is there a better alternative to mainWindow = MainForm.ActiveForm?
