couple of different ways you can handle it
I would probably do something like the following.
When the game starts instantiate a string called lettersUsed to be an empty string

then, when someone hits a letter, add it to the string if it isn't already there. (adding to the code from your previous post)

then when they hit space

great thank you. you guys are very helpful on this forum

ug im still consused though it always says lettersUsed is not defined. would any body mind giving sample code.

you probably need to do something like. This is all pseudocode

class Hangman{
string usedLetters= "";;
...
function startGame{
usedLetters = "";
}

}

call me stupid but i cant get it it always gives me erros index of... does not exist

send me your code

heres that part of it keep in mind im new




using System;
using System.Drawing;
using System.Windows.Forms;
using System.Runtime.InteropServices;


namespace WindowsApplication1
{
public partial class Form1 : Form
{
string keyData = "";

public Form1()
{
InitializeComponent();
string keyData = "";

}

protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
bool result = false;
switch (keyData)
{
case(Keys.A):
if(lettersUsed.IndexOf("a") = -1) lettersUsed+= "a";
break;

case(Keys.Space):
MessageBox.Show("Letters used: " + lettersUsed);
break;
break;





}
return result;
}


[DllImport("winmm.dll")]
private static extern bool PlaySound(string lpszName, int hModule, int dwFlags);


}
}

not sure y that play sound dll import is in there lol

here it is closer i think





using System;
using System.Drawing;
using System.Windows.Forms;
using System.Runtime.InteropServices;


namespace WindowsApplication1
{
public partial class Form1 : Form{
string lettersUsed = "";


public Form1()
{
InitializeComponent();


}

protected override bool ProcessCmdKey(ref Message msg, Keys lettersUsed)
{
bool result = false;
switch (lettersUsed)
{
case(Keys.A):
if(lettersUsed.IndexOf("a") = -1) lettersUsed+= "a";
break;

case(Keys.Space):
MessageBox.Show("Letters used: " + lettersUsed);
break;
break;





}
return result;
}


[DllImport("winmm.dll")]
private static extern bool PlaySound(string lpszName, int hModule, int dwFlags);


}
}
