Hi,

I am writing a code that compare richtextbox content with character(character code) , and then show a MessageBox .

this is my code :

C#

char[] st = new char[richTextBox1.Text.Length];
       st =  richTextBox1.Text.ToCharArray(0, richTextBox1.Text.Length);
       int a;



       for (int i = 0; i <= richTextBox1.Text.Length-1; i++)
       {
           a = Convert.ToInt32(st[i]);
           if (a == 113)
           {
               MessageBox.Show("Test");
           }

this code is running without problem for characters ,

as example : I have wrote a "q" in richtextbox , (code of "q" is 113) . when this program go to if statement compare all character and then find "q" and MessageBox.Show("Test"); run .

it is right but I want to this program compare "Enter" for me . How can I compare all characters in richtextbox with "Enter" ( It mean if "Enter" used in richtextbox content , return me a message ) ?!

Thanks in advance

Try these:

C#

private char chr_return = '\n';

private void rtfHasReturn()
{
     if (richTextBox1.Text.Contains(chr_return)) MessageBox.Show("test");
}

// want fancier looking ?
private void rtfFindFirstReturn()
{
   foreach(char c in richTextBox1.Text)
   {
       if (c == chr_return)
       {
           MessageBox.Show("test");
           break;
       }
   }
}
