There is a constructor for Guid that accepts a string-parameter.
A different solution could be to directly store the guid
(datatype uniqueidentifie r in sqlserver)
Hans Kesting
new Guid(GUIDString Variable);

Hans,
Ya I know - the table that I'm using the original developer created it as a
string (his code populated the GUID as a string). So sql srvr can't convert
it back to GUID once it's a string unless the table is empty. Which then
means that i won't be able to convert the id back, etc....you get the point.
Thanks.

Greetings All, I have read many upon many articles here regarding GUID
data types and uniqueness. There have been many opinions regarding
the effectiveness of GUID's and when they should/should not be used.
However, every article strongly implies, if it does not state it
outright, that GUID's are always unique. My question is this, what
happens if you have a database that uses GUID's and the NIC is changed
out on the box? From what I...

I am developing a kind of plugin framework that I can use for several

Obviously you can tell that each plugin object will have the overhead of the
ID. The question is, which consumes more overhead? A string object or a...

Hi,
The following is from MSDN.
"A GUID is a 128-bit integer (16 bytes) that can be used across all
computers and networks wherever a unique identifier is required. Such
an identifier has a very low probability of being duplicated."
My application will crush if I have two or more number that are
identical, so I need to know do I need to worry about this"

Is it possible to generate a 20 byte integer from a GUID that is "unique
enough" ( just like a GUID is not truly unique , but is "unique enough" ).
We identify transactions with GUIDs , but a partner web service has a 20
byte limit on transaction ID passed.

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.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.

For most users, this new feature is actually very convenient. If you want to control the update process,...
