Question ID: 29552
I'm parsing large amounts of text in VB and get this error: "VB
Run-time error 6 Overflow" I'm using the Len function to count the
charter length and that is where the error is raised. Example: x =

My question is how can I prevent this overflow error? Is there another
way to get string length say via an API call? Is Len running out of
memory and is there a way to increase it?

From the MSDN library:

"Long data type
A 4-byte integer ranging in value from -2,147,483,648 to
2,147,483,647. The ampersand (&) type-declaration character represents
a Long in Visual Basic."

The Len function uses the Long data type.  Just to clarify, your text
is not over 2,147,483,647 characters, correct?  If it's longer than
that, then that's probably your problem.  Thanks!

My text is nowhere near 2,147,483,647 characters so I'm not sure why I
get the overflow error. Current string size is only 500,000 +. Does
this help?

Can you post the source code for the function/method call in which
this error occurs?

Sometimes it is easier to see what is going on if you see the code.

This question has been answered by blcman-ga. Thank you and everyone
else for your comments. His answer to declare x as Long works
There is no answer at this time.

You must declare "x" as a long data type.
For example:

Dim x as integer
x = len(longstring) 'Longstring is a string over 32,768 characters in

Would cause an overflow error

Dim x as long
x = len(longstring) 'Longstring is a string over 32,768 characters in

Would work

The integer data type only allows values from -32,768 to 32,768. More
or less than that and you get an overflow error.

How about breaking the entire string in chunks of equal size and
getting length of each chunk. add all these lengths to get length of
entire string.
vStr="long string"
if len(vStr) > 32000 then
  break the string in chunks
end if
for i=0 to ubound(chunk)
 vLen=vLen & len(chunk(i))
