Question
smokn
Hi all , i'm quite a beginner in C# language , i wanted to write a program that uses OOP and requires the user to input an amount of cash and another amount to take it from cash , if the cash is lesser than the amount , it will display "Not enough cash." message . very simple ... here's my code :
And here's the Guy class code :
ok , now bear with me please , using this in Public form1()
if (double.TryParse(textBox2.Text, out x)) { guy1.guycash = double.Parse(textBox2.Text); }
requires that a numeric value must exist in textbox2 when the form loads up , but i want to leave it empty so that the user can enter a number in it !
if i left it empty the double.TryParse will return false and the whole program will broke since there will be no control holding guy1.guycash value ..
any help is appreciated , thanks in advance :)
