For 200 points to put you over ... How do I get an integer from a string (i.e. I have "45" in a textbox)

:D

I think we all know that points aren't that important to you but congratulations on being our first genius!

Cheers,

Greg Young

ooh... ooh! I know this one... um... it's something like

something like:

string str = "";
int txtLen = textBox1.Text.Length;

foreach(char c in textBox1.Text.ToCharArray(0, txtLen ))
{
      str += c;
}
                  
char[] ints = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9'};

foreach(char c in str.ToCharArray())
{
      if(Array.IndexOf(ints, c) < 0)
      {
            MessageBox.Show("Not a valid int");
            return;
      }
}

//valid if it makes it this far
int i = Convert.ToInt32(Convert.ToString(Convert.ToString(str.ToString()).ToString().ToString()).ToString());

-=)

Ah, just kidding, Congrats Bob!!!

Hey, Greg, I have a question open about serialization, and I know that you know a lot about the subject, and I would like to hear what you have to say.

P.S.  I'll take my points the good ol' fashion way, if you don't mind.  One more question and I am home free for genius #3.  These people around here are driving me crazy, though, cuz I have posted a lot of suggestions and good comments, but it is sooo quiet today, it just creeps up to just below 1000000.
