The following Code will not except a string with spaces in them, Also it will not work if the first letter is a sash "\" example

\OFFICE 67
\DIRECT

I'm scanning this data into a scanner program I developed using C# it blowes up when it hit a space or a "/"


if (!Char.IsLetterOrDigit(e.KeyChar) && e.KeyChar != '\b')
{
 
 
}

Hi,
What exception message do you get?
Where is the 'e'  variable coming from?

When I call the method below with ReadChar(new KeyPressEventArgs('/') I get no exception.
So are you sure your code "blows" up where you think it does?
What exception message do you get?
 public void ReadChar(KeyPressEventArgs e)
        {
            if (!Char.IsLetterOrDigit(e.KeyChar) && e.KeyChar != '\b')
            {
                
 
            }
 
        }

Sorry for the delay I have been on Vacation.

The problem is when I scan /INSTALL the first char is changed to ")" meaning when it finishes I have something like this

)NSTALL

 it takes the I out and changes the "/" to this ")"

Also it does not work for *INSTALL when I scan it.
