Hi,

i am wanting to detect whether a short string has numeral or operation characters within it, so that i may reject this string, 1000s of these will be sifted through, therefore i am wanting this to be as fast as possible.

Oviously checking the ascii codes of each character will not be efficient.
Using multiple Instr or Replace functions would not be efficient either, would it?

Please note, a string may contain letters and numbers, but is still rejected because of the numbers.

What do you recommend?
