I ran into this Microsoft Patterns & Practices Enterprise Library while i
was researching how i can write a database independent data access layer. In
my company we already use Data Access Application Block (DAAB) in our .Net
projects. We use SqlHelper in SQL based projects, and OracleHelper in Oracle

the DAAB but it was given as a helper code in a sample .Net...

Hey folks,
To me, this sounds like a crazy question, but I'll throw it out there
anyway.
Is it possible to change a variables data type half way through a running
program? If so, how?

Hi,
I have gone throught the group and Microsoft's online help and have
seen many suggestions but I am still seeking clarity:
1. I have an excel spreadsheet. Column A contains text that may be
greater than 255 characters.
2. I have an access database. I link (not import) to the contents of
the excel spreadsheet. In the design view in access, Column A has the
data type "memo".

Hello folks,
I got a few question on some basic data structure stuff. Sorry if
those questions might sound too easy or such but after googling a lot
I didn't find a real answer to all those questions so appreciate any
help.
I need to keep a very efficient data-tree structure (parent, previous,
next, first child, last child) within the memory which can be filled
up with billions of records. A struct place into the tree (I am using

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
