I am using asp.net 4.0 with VB.NET as the language and SQL Server 2008 for my database.
Question: When you have a .NET GUID for inserting in a database, it's structure is like this:
60 bits of timestamp,
48 bits of computer identifier,
14 bits of uniquifier, and
6 bits are fixed,
128 bits total Now I have problem with a GUID, because it's a 128 bit number, and some of the DBs I'm using only support 64 bit numbers. Now I don't want to solve the dilemma by using an autoincrement bigint value, since I want to be able to do offline replication.

how to determine this? I know how to get the "processor ID" etc. but this is apparently not a unique identifier.This is for an intel i7 975. My boss has asked us to make sure that no-one tampers with several parts of a process control computer.
View 6 RepliesAnyone know of a unique identifier I can grab from a Windows PC?I am working on licensing of my app and I want to assign the user a license key and have the key and some unique piece of data from the PC hit a database server of mine and then check credentials before the program runs.I thought about using host name but that can be cloned. I also thought of MAC address but if a computer has a wired and wireless NIC then there are multiple MAC addresses.
View 2 RepliesI have a table in an SQL database bound to a datagridview and am having an issue with understanding what happens when I add a new data row.
My datatable is built in code with the first column created using this sql command...
vb
cmdString = String.Format("CREATE TABLE {0} ({1} INT IDENTITY(1,1) NOT NULL, ", tableName, columnNames(0))
after that there a a number of other columns added to the command to build the table. After the table is created, I fill the datatable and bind the datagridview using this code....
vb
Dim cmdString As String = String.Format("SELECT * FROM {0}", DB_DATALOG_TABLE_NAME)
DataLogAdapter = New SqlDataAdapter(cmdString, dBConnection)
DataLogTable = New DataTable
[Code].....
This is where my understanding is falling. Because I have created the datatable's first column with the NOT NULL key word, an exception throws when I try to update the data adapter because the first column of the data row is empty By creating the table with the first column the IDENTITY key word, doesn't that imply that the database will generate the value for that column? If so, when I add a new datarow, how does the identity column get filled?
I am looking to return a machine specific unique identifier from an EXE. I've tried MAC, hard drive serial and CPU ID, but all contain alpha characters. This makes returning them as an integer difficult - integer seems to be the only type you can return from an EXE.

I have a read-only mssql-view, and I want to map it to nhibernate (using hbm.xml files). The view is a select that joins two tables. For give an abstract-insight, the select is something like this:
SELECT A.Id As A_ID, B.Id As B_ID,
A.AttributeA, B.AttributeB,
FROM A INNER JOIN B ON
A.Id = B.RootID
It's a one-to-many relationship between A and B (B entries are dependant/leafs of A entries).
I'm using nhibernate's hbm.xml files, and I can't make it to work. I'd gladly appreciate if someone can enlight me of the kind of XML that I have to use, I guess that as my view has no ID, I have to create a composite-nhibernate id (wich will be the ids os A and B together) but I couldn't make it to work. Also the view is READ ONLY so I think that should make the solution easier.
In my [2005] application, I use the MacAddr / CpuId / DiskId of the computer to validate my licence using the WMI calls. The problem is we just can't thrust this feature because on a good percentage of the computers this feature is not installed properly or completely disabled.The users are not experienced, they are located in a remote location and I just don't feel like debugging their Windows installation every time they want to try my application.Is there a working alternative that I can use that will always return me a unique identifier for every computer which will always be available on 2000 / XP / Vista systems?

To be clear: I am not doing this with malicious intent. I am working on an e-mail integration component that utilizes both UIDs and a "Last processed" date to locate the first new e-mail to integrate. I want to test cases where multiple e-mails have the exact same date/time - as the e-mail integration module should handle those situations flawlessly. If I could simply fake the date this way, I could send as many e-mails as I wanted that matches a certain date/time, rather than trying to send them with an automated script - hoping they will all be received within the same second.
I've written a testing program where my students write a test and the results are compiled in a text file. The text file is then emailed to me using SMTPServer.send(MyMailMessage). The program works, except that it takes a number of seconds for the email to be sent. The user clicks the next button, which should bring him/her back to my login screen for the next student, but instead it hangs while sending the email. How do I get it to do the emailing in the background, allowing the person to continue using the program?
