Reading values from the settings.settings file.

Hi,

I have this methode:

        private void edtVal1_Validating(object sender, CancelEventArgs e)
        {
            if (Properties.Settings.Default.IsMGDL)
            {
                int intVal = Convert.ToInt32(spdVal1.Text);
                if (intVal < 70 || intVal >= 140)          <===========
                {
                    XtraMessageBox.Show("The value must be between 70 and 140", "Error");
                }
            }
            else
            {
                double doubleVal = Convert.ToDouble(spdVal1.Text);
                if (doubleVal < 1.0 || doubleVal >= 35.0)   <===========
                {
                    XtraMessageBox.Show("The value must be between 1.0 and 35.0", "Error");
                }
            }
        }

Select allOpen in new window

My question is about the values in the code line that I have marked with an arrow.
Instead of specifying values I would like to read the values from the settings.settings-file.

Like this:

if (intVal < Properties.Settings.Default.MinVal || intVal >= Properties.Settings.Default.MaxVal)

Select allOpen in new window

But I get errors:

Operator '<' cannot be applied to operands of type 'int' and 'string'      
Operator '>=' cannot be applied to operands of type 'int' and 'string'      

What can I do about this?

Greetings,
