Text Encoding - ASCII

[Amjad]

Hi,
Why do I get this character (ÿ) when I try to display the
blank ASCII character number 255?

MsgBox (Chr(255))

I think I need to set the text encoding to ASCII somehow,
but I don't know how. Any ideas?

7-bit ASCII has no character 255. I suggest you read

http://www.joelonsoftware.com/articles/Unicode.html
http://www.yoda.arachsys.com/csharp/unicode.html

MsgBox (Chr(255))

Chr(255) will give you whatever character that has #255 according to
your current ANSI code page.

There is no ASCII character. ASCII has only characters from 0 to 127,
it's a 7 bit encoding.

Thanks.
How can I receive (in a string) only ASCII characters
from the user's input textbox and simply ignore non-ASCII
characters if there was any?

Amjad,

That sounds like a great way to make non-English users hate your
application.

But if you really want to do it, I suppose you could scan the string
for any characters with a value >=128, since the first 128 characters
of Unicode are the same as the ASCII IIRC.
