Edit string problem

Hey!

Im trying to replace one char in my string with another one. Obviously i don't know what's wrong because then i would fix it. :P W/e, here's my code:

Code:

---

textBox4.Text[Convert.ToInt32(var)] = Convert.ToChar(var);

---

The compiler sais:

Code:

---

Error        1        Property or indexer 'string.this[int]' cannot be assigned to -- it is read only        C:\Users\HP-användare\Documents\Visual Studio 2008\Projects\Hangman\Hangman\Form1.cs        132        17        Hangman

Thank you!

I've googled it many times, but i can't find the answer. I can give you all the information about the code, just tell me.

Strings are immutable so you can't manually assign individual characters as you can in say C++. Look up the string methods Replace/Remove/Insert as they may be what you seek.

Thanks for your help!

Code:

---

        /*########################################*/
        /*########################################*/
        /*########################################*/
        private String String_Replace(String strText, String strFind, String strReplace)
        {
            try
            {
                int iPos = strText.IndexOf(strFind, System.StringComparison.CurrentCultureIgnoreCase);
                String strReturn = "";
                while (iPos != -1)
                {
                    strReturn += strText.Substring(0, iPos) + strReplace;
                    strText = strText.Substring(iPos + strFind.Length);
                    iPos = strText.IndexOf(strFind);
                }
                if (strText.Length > 0) strReturn += strText;
                return strReturn;
            }
            catch
            {
                return strText;
            }
        }
        /*########################################*/
        /*########################################*/
        /*########################################*/

Is that what you need?

hm, You could I guess split your string into an array of bytes, replace your char there and then put it back together building a string.

Got a question...
How can i store a word so i can get it from all classes? This doesn't work, but you might understand what i want.

Code:

---

public struct holder
{
      int io;
}
public class save()
{
      holder save = new holder;
      save.io = 1;
}
public class print()
{
      holder print = new holder;
      if (print.io != 1)
      {
            //true
      }
}

---

Well, the int io should stay at 1 not change. How do i do that?

If you need to reach a variable from outside a class, you do it as "public ..." , if not "private ..."

Code:

---

public class MyClass(){
public string ThisVariableCanBeReached;
private string ThisVariableCanNOTbeReached;
}

---

So you'll be able to use
MyClass TEST = new MyClass();
TEST.ThisVariableCanBeReached = "bla bla";

If you need something which "doesn't change", try "public const"
public const string ThisCanNotBeChanged = "Can't touch this!";

When i try public const string... i get an error:

Code:

---

Error        1        Member 'Hangman.Form1.holder.word' cannot be accessed with an instance reference; qualify it with a type name instead        C:\Users\HP-användare\Documents\Visual Studio 2008\Projects\Hangman\Hangman\Form1.cs        71        37        Hangman

Why?

Show me the code, not that weird long error without a line break in it! ;)

Well since my computer crashed, it will take a while before... I must recode all! :(
