[RESOLVED] How to make debug messages

[bixel]

Is there a way to send messages to error box or something. I have some steps in a method that sends feedback to a textbox. The problem is this part

                //If parryroll was greater than their ParrySkill then they failed
                if (parry == true) //parry ability true, opponent can Parry!
                {
                    parryrate = parrySkillOpponent; //Opponent's skill in Parry
                    Random randParry = new Random();
                    parryroll = Math.Abs(randParry.Next(1, 100));
                    if (parrySkillOpponent < parryroll)
                    {

never seems to happen, even when I set parrySkillOpponent over 100.

(BTW) The Parry skill is enabled true by a check box. Maybe I am not correctly checking if the checkbox has been checked? If so what is the correct way to check if a Checkbox has been checked?
