Well, if you have a textbox (or edittext) control, you can get its value
seq = getText(MyEditBox)
and then use sprintf() or value() (?) to get its value.
num = sprintf("%d",{seq})
Or somethin' like that.

To clarify:
This question has nothing to do with Win32Lib, so long as you can getText()
or whatever function this library uses to retrieve the string of text. You
are talking about converting a text string to a number; this is usually
done with a language specific function and not through the Win32 API.
Do not use sprintf(). This function is designed for converting *variables
and constants* to strings. The user has entered a string, so your task is
in fact to do the complete opposite - which is value(). This converts a
string to a euphoria object. For example, the string "083210" would convert
to the integer value of 83210.
I suggest you experiment around with value() a lot. Check it has been
parsed correctly (the first element of the returned sequence identifies
this).
If you wish to parse for an integer only, then:
--------------------------------
sequence s s = value(text_to_parse)
if (text_to_parse[1] = GET_SUCCESS and integer(text_to_parse[2])) then
-- do something
end if
--------------------------------
Help File Examples:
Example 1: s = value("12345"}
-- s is {GET_SUCCESS, 12345}
Example 2: s = value("{0, 1, -99.9}")
-- s is {GET_SUCCESS, {0, 1, -99.9}}
Example 3: s = value("+++")
-- s is {GET_FAIL, 0}
It is a generic function, to

Actually that would NOT work because sprintf() converts a number to a text
format and not the other way round.
With win32lib you can simply do:
num = getNumber(MyEditBox)

I'm not sure that value() does what you want. This is how I solved it for=
myself:
Louis.
-----------------------------------------------------------------
-- s2n -- Convert a numeric text string to an integer
-- Note: This only works for positive integers
-----------------------------------------------------------------
global function s2n(sequence s)
atom n
s -=3D '0' -- Convert ASCII to BCD
n =3D s[1] -- First digit
for i =3D 2 to length(s) do
n =3D n*10 + s[i] -- The rest of the digits
end for
return n -- Return the number
end function
