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.

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 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?

I have a combo box, I have entered in 6 different world wide destinations for example:London, Paris, New York etc The program is for booking plane tickets, at the moment the user has to input the cost of the journey manually into a textbox and then depending on the number of tickets requested will calculate the cost.
What I would like to do is to assign a unique numeric value (the specific cost of the flight for one ticket) to each of the items in the combo box list so that when a user selects a destination the default cost of the ticket is already known and does not require the input of the user.Private Sub cmbDestination_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmbDestination.SelectedIndexChanged End Sub The idea is that which ever destination is selected, for example: Paris - �155 would then set the variable 'ticketPrice' to 155 and allow me to change the calculations of the program to not require user input.
Frustration has officially set in. This is my first post here, and to be very honest, I'll admit that I'm a newbie VB programmer as well. I guess that's why I'm posting here, in hopes you super-porgrammer types might be able to help.
I've written a smallish VB program with 2010 express... the code uses some text files to gather various lists of numbers ( as part of a manufacturing Bill of Material ) that assiciate to PDF files of the same name. The intent was simply to view and print the gathered existing PDF files.
I have the program mostly working the way I want ( at home ), but when I bring it to work, it fails to open.
My home PC is a 32Bit Windows Vista Machine with Adobe 10.1 viewer installed.My Work PC is a 64 Bit Windows 7 Machine also with Adobe 10.1. I've sent the .sln and code to a buddy who is also running a 64bit Win 7 machine very similar to what I have... he is able to run the program. I've sent the same thing to my work pc and tried to run it. I get some crazy HRESULT error I can't make heads or tails out of... remember I'm a newbie.
I will happily post code if you guys are interested, but I believe that it isn't code related. What kind of things MIGHT i try to look for on my work pc that would cause this simple program Not to function? I've brought other programs I've written to work without problem. But this one has me stumped.
Other things I've tried:
1) uninstall and re-install Adobe... ( no change )
2) written a super small adobe viewer program at work... ( works )
3) tried to comple as "any CPU", "x86", and "x64"... ( does not work )
4) bring .sln & code files to compile and run at work... ( does not work, HRESULT err )
Say a machine has two seperate IP's. I am running a little test program that connects to an outside piece of hardware that has it's own IP. I receive data from that hardware. I want the same little program assigned to the two seperate IPs on my local machine to get the same data from the hardware. How can this be done?I am receiving data just fine but I am not seeing how to tie the program to a specific IP on the local machine. As soon as I run another instance of my program, not data is received on the second instance.For example: I have a program running on a machine. I want two instances of that program, each on it's own ip
Instance 1: 192.168.1.240
Instance 2: 192.168.1.241
I want both instances to listen for data coming from 192.168.1.50
This is a generic example of what needs to happen. I need to know how to define the local IP's the UDPClient is running on.
I am using VB .Net to access the eBay API and store all completed orders in a database. This database is then fed into a proprietary shipping system, which can not handle an order number larger than 20 characters. eBay returns an order number like so 230407279314-680141236013 which is too long. The order number is always 12 numbers a hyphen and 12 more numbers. What I need to do, is turn this (the result can be alpha numerical) into a shorter, unique order key to store in my database alongside the true orderId (so that this can be referenced by the shipping software instead of the actual order number). The reason for the 20 character limit is the barcode algorithm used. Is there any way to achieve this in VB .Net 2010? This number can be anything unique, so long as it does not exist already (even a good uniqueid function would work, but I would have to query the database to make sure it isn't taken)

If you try and do the same in a control that inherits Control, you get an error,Keyword is not valid as an identifier. Since Step is a keyword via the For Next statement.
So, how do you achieve the same as the ProgressBar has done in a custom control?
