             "Data Sender",
             MessageBoxButtons.YesNo,
             MessageBoxIcon.Warning);



        if (result == DialogResult.No)
        {
            e.Cancel() = true;  //ITS ASKED ME AM I MISSING A DIRECTIVE OR ASSEMBLY REFRENCE (FOR CANCEL)
        }

Answer 1

In an if-else only the if should have a condition, and the else should not. Use an else if statement to explicitly define a condition.

if (Nuts.Checked)
{
        this.Tag = "checked";
        sw.WriteLine(Nuts);
}
else if(Cherries.Checked)
{
    this.Tag = "checked";
    sw.WriteLine(Cherries);

}
else if(Sprinkles.Checked)
{
    this.Tag = "checked";
    sw.WriteLine(Sprinkles);
}

Flavorbox is a textbox, so by doing if(flavorbox) you are checking if flavorbox is equal to true or false. It's a textbox so this isn't possible. You'll probably have to just change the flavorbox. Try the following:

if(!String.IsNullOrEmpty(flavorbox.Text)) {
    sw.WriteLine(flavorBox.SelectedItem);
}

Answer 2

1. about

if(flavorBox)

what are you checking?

about the:

else(syrupBox) and else(Cherries.Checked)

you cannot do else(something) . you can do else if(something) because else is all the rest of the options. so change them to: else if(syrupBox) and else if(Cherries.Checked)

2. about the cancel: what are you trying to do?

when you click no in the dialog, what are you trying to accomplish with the e.cancel ?

Answer 3

For the fourth error, note that EventArgs.Cancel is a property, not a method. Remove the brackets:

e.Cancel = true;
