Buffer Leaks

I've had this a few times.

Can someone explain what a buffer leak is, and how are they avoided.

I downloaded the ExtraSort demo and in non-debug mode I get loads of errors saying the buffer leaked?

How do I plug the whole? Do I need a big cork?

Well there are 2 leak messages the buffer manager gives and since you didn't specify the exact message I don't know which one you are getting and they happen in very different scenarios. I will explain them both but they are both a component coding error.

1. This buffer has been orphaned...
This is when the engine is shutting down but a component still has a reference to a buffer. This usually mean the component has actually leaked a buffer since when the engine is shutting down everything else in the dataflow has already finished.

2. A call to ProcessInput unexpectedly kept a reference...
This is when a component calls AddRef on a buffer that it was passed in a process input call. This is not allowed. A component that needs to keep a buffer around that it was passed on process input must call clone on the buffer not addref.

You can't do anything about this problem. The component author must fix their component to resolve these problems.

Bother switching from MSDE to Access database?

We wrote our .Net 2.0 application using MSDE.
However, the demo programs we have sent out
many times have trouble installing MSDE on the
customer's computer.
We are thinking about converting our database from
MSDE to access because of this practical problem.
The question is this:
Will the sql server 2005 replacement for MSDE have
an easier time installing than MSDE?
thanks in advance

jay,
I'll let the SQL Server experts here address the installation issues of SQL
Express. My limited experience with Express is that it is an easier install.
But if you're considering Access I thought you might be interested in SQL
Server Compact Edition:
http://www.microsoft.com/downloads/details.aspx?FamilyID=85e0c3ce-3fa1-453a-8ce9-af6ca20946c3&displaylang=en
Although the current download is RC1, release is expected for the first week
in December. Installation can be as simple as copying a few DLLs and a
database is a single file, but you would need to change your .NET 2.0 code
slightly to use the SqlCe namespace rather than SqlClient. SQL Compact also
does not support stored procedures or triggers, but then neither does
Access.

|||For SQL Express the setup has been completely rewritten but it still uses
the Windows installer technology so there are places where it can fail. For
demo purposes you might want to look at SQL Server Compact Edition. It is
smaller and simpler than SQL Express or Access. It doesn't have all the
features of SQL Server Express but it is more compatible than Access would
be.
