Robert, Must be something special (ie, bad) I'm doing in my init function, because multiple varbinds works on the netSnmpIETFWGTable example. Let me dig some more.

Index is 1, and row exists. This makes the exception happen: snmpset -v2c -c private udp:135.5.184.98:161 someOid.2.1 i 3 someOid.3.1 s 1152304 someOid.4.1 i 3 Thanks, Phil Gillis -----Original Message----- From: Gillis, Philip W (Philip) Sent: Wednesday, December 08, 2004 8:43 AM To: '[EMAIL PROTECTED]'; Gillis, Philip W (Philip) Subject: RE: windows exception on multiple varbind set Hi Robert, Yes, I typo'ed 5.1.2 into 5.2.1. I installed 5.2, and table_dataset.c has the fix you describe here, but it still has the problem. This is on win2k pro, 5.00.2195, Service Pack 4, and VC++ 6.0. Below is a stack trace, which looks very similar to the one in 5.1.2. Here's how I can make it happen: SomeOid is a table with 3 columns, integer, octet string, integer. snmpset -v2c -c private udp:135.5.184.98:161 someOid.1 i 3 someOid.2 s 1152304 someOid.3 i 3 Very consistent.
