ASP Function : ASCII to Integer

[AkutaSame]

I know this will sound a bit newbish, but then again, I'm an ASP newbie. I know it can be done with other scripting languages. What I am looking for is an ASP function that will convert a string/ascii characters into integers.

Logic:

A text box contains a number. I want to submit this number to SQL through a query, but must modify the number using some sort of algorythm first. Thus, I need to be able to take the string, convert it to a number, modify the number accordingly and submit the new integer variable to SQL in a string.

I know how to submit variables to SQL in ASP, that's not the problem. It's just converting from the original string to an integer in order to do the modification before submission.

Any there that can help?

<%
MyVariable = CInt(myVariable) 'Converts myVariable to Integer
MyVariagle = Clng(myVariable) 'Converts MyVariable to Long
MyVariable = CStr(MyVariable) 'Converts MyVariable to String
MyVariable = CBool(MyVariable) 'Converts MyVariable to Boolean
MyVariable = CDbl(MyVariable) 'Converts MyVariable to Double
MyVariable = CSng(MyVariable) 'Converts myVariable to Single
%>
etc.

In VB6, there is a function call CInt(expression) which return the an integer value. You can try that.

You can do something like:

intValue = request(&quot;textbox&quot

If CInt(intValue)= 1 then
'do something
else
'do something
end if

To convert characters to ASCII numeric: Asc(character)
To convert ASCII numeric to characters: Chr(integer)

So Asc(&quot;a&quot will return 97 and Chr(97) will return a

Can I just add, that cINT(sExp) will fail with a Type mismatch error if sExp does not contain a string of only numeric characters.

i.e cInt(&quot;one&quot will fail
cInt(&quot;1one&quot will fail also
cInt(&quot;1&quot is fine though.

I always use the isNumeric function first, i.e

if isNumeric (sExp) then
vExp = cInt(sExp)
else
gracefulyFail....
end if

Is there a simpler way than this?

p3t3:
not to mention that VBscript integers have a very low range.. the following will fail:

CInt("32800")

And yes I think using IsNumeric is a good way to fail gracefully
