Error in Managed .NET Sybase Provider

Getting this error with your Sybase .NET driver? There is limited discussion that I found via Google, so I thought I would mention the solution here:


ERROR Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

at at Sybase.Data.AseClient.Unmanaged.ExecuteCommand(IntPtr pCommandHandle)

at Sybase.Data.AseClient.AseCommand.Execute()

at Sybase.Data.AseClient.AseCommand._ExecuteReader(CommandBehavior commandBehavior)

at Sybase.Data.AseClient.AseCommand.System.Data.IDbCommand.ExecuteReader()


To fix this, contact Sybase and get the latest managed driver from August 2008:

Sybase.AdoNet2.AseClient.dll and Sybase.AdoNet.AseClient.dll

Version: 1.15.325.0

Released 15th August 2008

The difference between the 2 DLL’s is that one is for .Net 1.0 and the other for .NET 2.0.

This is apparently from the Sybase SDK, and Sorry, I can not provide this to you at all. Please contact Sybase!
