Problem when using the "using" keyword

I'm using the "using" keyword to load a dialog where the user enters the captcha code from a webpage, but the problem is the dialog is loading and closing instantly. How can I ensure the dialog waits for user input?

using (Form2 captchaDialog = new Form2(captchaImage))
{
    captchaDialog.Show();
    captchaText = captchaDialog.captcha;
}

You could use ShowDialog method instead:

using (Form2 captchaDialog = new Form2(captchaImage))
{
    captchaDialog.ShowDialog();
    captchaText = captchaDialog.captcha;
}

Your form is closing immediately because your code hits the end of the using block which will dispose the newly created form, which in turn close the form if it is open. You have to block your call to the dialog by using ShowDialog.

using (var dialog = new Form2(captchaImage))
{
    if(dialog.ShowDialog() == DialogResult.OK)
    {
        captchaText = captchaDialog.captcha;
    }
}
