PLEASE HELP! how can i know if a piece of text is a number or just a letter?

[programmer]

hey,

how can I know if a piece of text is a number or a letter?

thanks in advance!

Try ISNUM.

[programmer]

there isn't such function "isnum".

Methinks VB is 'IsInt' or 'IsDigit'...Something along those lines...

Strings are 'IsAlpha' I think too...

Looked it up in that 580some megs of MSDN and to check if its a number you do:

If IsNumeric(BlaBlaBla) = True then

' etc.

end if

Letters are:

If IsAlpha(Variable) = True then

' etc.

end if

Okay - if you have a text box say it's name is txtText, and you want to validate the text within that text box to make sure it's numerical, you would type

IsNumeric(txtText.text)

Usually you would use this in an if then statement such as

If IsNumeric(txtText.text) = False (meaning not a number) then

.....

else (if it is numeric)
......
