Btrieve Problem

I have wrong betrieve file (as I assume) DOS application works on it OK. But
Windows application (wbtrv32.dll) fails.
How to make Win32 app to be fully compatible with DOS app. Or how to import
data from these file using win32 app.


I've got DOS application which stores data in btrieve files.
I want build Windows application who connects to these betrieve files
When I try to connect to most of the files everything is OK. But when I try
to connect do 1 file windows application (Visual Basic 6) stop, I want only
import file. Record by record.
The message is "wrong page in module KERNEL32.DLL"
To connect to these file I've use Visual Basic 6; Pervasive for WorkGroup
2000 (+ service Packs)


Example btrieve file and more info on page:

Obviously, your application is functioning, and it is accessing the Btrieve
database just fine. However, this one record type may just be causing a memory
overwrite, and once memory is trashed, bad things happen.

Re-examine all of your source code as it accesses this "bad" file. Make sure
that you have sufficiently large buffers for both the data buffer and the key
buffer. Be very wary of the "variable-length string" capabilities of VB -- you
may need to use some special workarounds or another way to access it. Check
your Pervasive.SQL SDK, or the Pervasive website, for examples on how to work
around this. (Search on "BASIC".)
