Hey people...

I'm really not very good with c#, this is pretty much my first crack and I like it...but i'm pretty stuck and would really appreciate some help if you could

I'd like to get a string from textbox1, then on button click, send this text to textbox2 with 'x' after every other character in the string originally in textbox1.

In other words, textbox 1 would read "this is a string", then on button blick, textbox 2 would read 2= "txhxixs xixs xa xsxtxrxixnxg" it may seem a little daft but its for writing data to a com port, but the output theory would be the same...

So something like:

C#

private void button1_Click(object sender, System.EventArgs e) 
{
  char[] inputtext = textBox1.Text.ToCharArray()
  string letterx = ((char)120).ToString();
  for (int i = 0,i<inputtext.length;i++)>
  {
   textBox2.Text = (inputtext, i, 0);   //***
   Thread.Sleep(200);
   textBox2.Text = (letterx.ToString());
   Thread.Sleep(200);
  }
}

So far i've been writing to the com port using serialPort1.Write(inputtext2, i, 1), but this only seems to send a single character

i'd really appriciate any help you guys could give

cheers,

M

hey wizzard thanks for the reply...it comes up with a loads of errors, something to do with lamda conversion (??)

and Hi mark. Basically for a small uni project i've built a bluetooth pager with an LCD controller. The long and skinny of it is a bt controller recieves a character sent from a comp port and uses that data to control an LCD driver.

I have coded the hardware to respond when a character is recieved from a com port, but then the character 'x' must be recieved between instructions for a valid port signal to be recieved.

Everything is working well, But i can only enter 1 character at a time into my C# application...hence the reason I need to break down a string, add x to every second character and send it...does that make any sense?

Just a heads up, you should reply to the individual answers and not post this as a new answer.

So you're using the x as a delimiter or something? Will behavior be impacted where ever you are sending this if 'x' is the character inputted?

Solution 1

Hmm, try:

MIDL

textBox2.Text += (inputtext, i, 0);
Thread.Sleep(200);
textBox2.Text += (letterx.ToString());
Thread.Sleep(200);

I don't understand where the writing to com port comes in or why you are using Thread.Sleep()?

C#

StringBuilder sb = new StringBuilder();
foreach(Char c in textBox1.Text)
{
    sb.Append(c);
    if(!Char.IsWhiteSpace(c))
    {
        sb.Append("x");
    }
}
textBox2.Text = sb.ToString();
