Question

In VB6, what is the likely cause of an Overflow error? I am using strings when it occurs.

Is it RAM, or hard-drive space? Or is it something internal to VB6?

Answer 1

Another ‘stab’, since no code is provided …

The following will produce an overflow error:

Dim x as integer
x = len(longstring)   'longstring over 32,768 characters in length

Would cause an overflow error.

Dim x as long
x = len(longstring)   'longstring over 32,768 characters in length

Works fine.

Another example of an overflow from Microsoft Support here:

EDIT

A more subtle situation that can catch you off guard:

You attempt to use a number in a calculation, and that number is coerced into an integer, but the result is larger than an integer.

Dim x As Long
x = 2000 * 365 ' Error: Overflow

To work around this situation, type the number, like this:

Dim x As Long
x = CLng(2000) * 365
