Solution 1

The check box is easy: create an event and a property in Form2 which Form2 handles. When the checkbox is clicked, signal the event and form1 can access the property to decide if the button should be enabled or disabled.
Transferring information between two forms, Part 2: Child to Parent[^] Shows you how to do it.
Saving is more complex: it depends on a huge number of factors, such as how you want to save it, how much there is to save, and so forth.
The easiest is to use Settings, then there is a file you read and write yourself, then CSV, XML, a database, and finally the registry - and that list is in the order in which I would start looking.

So how much do you want to save?

OK - look at your project in VS, and open the "Properties" branch in the Solution explorer pane.
Double click on "Settings.settings" and a settings page will open.
Change the "Name" to "ButtonEnabled" (or a name that makes sense given what the button does) and change the "Type" to "bool". Leave "Scope" at "User", but set "Value" to "True" - this will allow your button to power up enabled when it runs for the first time.
Save and close the settings page.
Now, if you don't have one, add a Load event handler to your Form1, and add the line:
myButton.Enabled = Properties.Settings.Default.ButtonEnabled;
Then, when you change the Enabled status just add:
Properties.Settings.Default.ButtonEnabled = myButton.Enabled;
Properties.Settings.Default.Save();
And the system will do everything else for you as regards storing it.

Hi,

Assuming that you have 2 buttons on Form1, and their names are: button1 and button2, you need to create settings (1 link will be good for start) for each control state you want to save. Example:
1. Setting name: Button1Enabled, Type: Bool
2. Setting name: Button2Enabled, Type: Bool

Then you should handle your Form1 events to store/restore buttons state.
1. When the form1 is closed save your settings to configuration file:

C#

protected override void OnClosed(EventArgs e)
{
    base.OnClosed(e);
    Properties.Settings.Default.Button1Enabled = button1.Enabled;
    Properties.Settings.Default.Button2Enabled = button2.Enabled;
    Properties.Settings.Default.Save();
}

2. Whe the form1 is loaded load your setting from configuration file:

C#

protected override void OnLoad(EventArgs e)
{
    base.OnLoad(e);
    button1.Enabled = Properties.Settings.Default.Button1Enabled;
    button2.Enabled = Properties.Settings.Default.Button2Enabled;
}

For further referrence you should take a look at this links:

Hope it helps you :)

XML

in general for work in this domain you should have some knowledge of reflextion (meta programming)
but for your problem you can use <b>control.controls</b> to coloect list of control
then save in an suitable data structure.
use code same as this :
<pre lang="c#">
        private void button1_Click(object sender, EventArgs e)
        {
            listBox1.Items.Clear();
            foreach(Control c in this.Controls)
                if(c is CheckBox)
                    listBox1.Items.Add(c.Text+":"+(c as CheckBox).Checked);
        }
