Question

I have a windows forms application and I need to get an input from user. I decided to use another form. The code in my main windows form like that :

inputPage p = new inputPage();
p.Visible = true;
VBand = p.getValueDouble();

My second form ( where I get the input from the user ) is simple. It contains only a label, textbox and ok button.
My problem is, I want to call getValueDouble function (3rd line of the code above) after when we are sure that user enter the value and press the ok button. So how can I do this?
Thanks..

You probably want to use the Form’s ShowDialog() method. This will cause your current function to wait until the user clicks the button to close the form.

inputPage p = new inputPage();

DialogResult result = p.ShowDialog();

if(result == DialogResult.OK)
{
    VBand = p.getValueDouble();
}

The OK button on the form should have its DialogResult property set to DialogResult.OK.
