Ryou need to convert it to a string, which you can do by doing
a.ToString()that is pretty strange though, you are basically just setting
textBox1.Text
Sthanks, i totally forgot about that
Jplease stop making additional threads for the same problem
Jthis is the 3rd one
Sit's a different one
Jit looks like the same thing z showed you an example of in the last thread
J
Shis example didn't apply
Sint a, b, c;
if (int.TryParse(textBox1.Text, out a) && int.TryParse(textBox2.Text, out b)) {
textBox1.Text = a.ToString();
textBox2.Text = b.ToString();
c = a;
textBox1.Text = b.ToString();
textBox2.Text = c.ToString();
}
if (int.TryParse(textBox1.Text, out a) && int.TryParse(textBox2.Text, out b)) {
textBox1.Text = a.ToString();
textBox2.Text = b.ToString();
c = a;
textBox1.Text = b.ToString();
textBox2.Text = c.ToString();
}
S_
Jyou can say so in that thread
Sint a = Convert.ToInt32(textBox1.Text);
int b = Convert.ToInt32(textBox2.Text);
int c;
textBox1.Text = a.ToString();
textBox2.Text = b.ToString();
c = a;
textBox1.Text = b.ToString();
textBox2.Text = c.ToString();
int b = Convert.ToInt32(textBox2.Text);
int c;
textBox1.Text = a.ToString();
textBox2.Text = b.ToString();
c = a;
textBox1.Text = b.ToString();
textBox2.Text = c.ToString();
Jmaking new threads for every small change makes it hard to follow
Swhich is better
Jto me, neither
Ji see no reason to convert them to and from integers if you just want to swap the contents
Sdoes it go up?
J?
Smy post
Jthe same people that responded will still be there
Jleaving them hanging to make a new post just makes it slower for you to get answers
Swhat would be more professional?
Jremove all the unnecessary conversions
Jyou can swap 2 variables in 3 lines, or even make it a single line if you use a trick with tuples
S
Jyes, this is a picture of code
Sthere's an error..
Jthere is indeed
Si removed the conversion as you said and got an error
Jwriting code involves understanding the code you're writing
Jdo you know what that error means?
Sno
Jyou declared a variable but never assigned it a value
Jin this code a, b, and c are all uninitialized
Jyou probably don't want ints either, because you're working with text
Swhat value should I give it to
SI'm swapping numbers
Jvalues of text boxes aren't numbers, they're strings
Junless you need to do math with them there's no reason to parse them to actual numbers
Sthey can be used for numbers
Jto solve the "swap 2 numbers" problem you don't actually need to make them numbers, because the problem is really "swap 2 variables"
Jyou only need a single extra variable to solve this problem
Swhich is?
J...a single extra variable
Jit wasn't a trick question
Sfor some reason you make me feel stupid lol
Su don't give direct answers
Jcorrect
SI want to get spoonfed
