I've seen threads on this topic posted before but they didn't come up in the search that I did. What's the best way to get a computer id code of some kind that is unique for each computer so I could use that to create a unique software activation code?Does Visual Basic have any staements that can give you this kind of information.
View 18 RepliesBasically I'm adding a registration feature into my program, or a similar thing to that. So, when you purchase you can install up to 3 copies (for example), but not more.To do this, I need to know some kind of information that is unique to each computer (to store in my database online), I thought of the name of the computer, but that isn't unique, obviously.

I am creating files and then allowing the User to browse through the files via a ComboBox. I decided to name each file the current date. In order to create multiple reports each time the application is ran, each report needs a unique name.
The idea is that if they run a report once a day they'll have a unique report each day. But, then I realized that it is feasible that User could run a report more than once a day. So, I decided to create an integer and increment it each time the report has been ran. Then append the file name with that integer. So, report one of that day would show something like this:
12-22-2009_1 and so on.And this works just fine. But, if the user decides to close the app and then run the report later that day, the variable has been reset and no longer works as needed.I'm using a StreamWriter to create the file.

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?

View 5 RepliesI once posted a question on generating a policy number by table ID and user selctions from comboboxes. [URL]FYI . I am doing my project in vb, that why i posted it here. I managed to do that when i choose a region and product from two different comboboxes i generate a number but now my problem is that whenever i click on the comboboxes a policy number is generated before i save the record, so if my previous nummber was 72100002 whenever i click on the product combobox i generate a number e.g if i click on it five times by the time i save the number would be 72100007. I am using a stored procedure for this. Is there another way of doing this or i might end up with my first record as 72100001 and my second record 72100006.

I have an application that is made for a game that you have to draw cards for. So what I have done is created a random number generator that generates a random number and then using case statements that number is associated with a picture of the card, which is displayed in a picture box. This part works fine. Each time I draw a card it is not reshuffled so I need to store the random number generated and then if that number is generated again ignore it an generate a new number.
Now to complicate matters even further when a certain card is drawn the entire deck is reshuffled and everything starts over again. Here is what I tried... I tried using arrays to store the numbers but I cannot seem to get it to search the array for the number or store the number properly within the array. The array has to be dynamic since the game is expandable and I will be adding more cards to the game in the future.

View 9 RepliesHow would I go about generating a unique receipt number in the following range:
GA00000-GZ99999? I am not allowed to use the 'I' and 'O' letters so GI00000-GI99999 & GO00000-GO99999 would be excluded. Ideally, I'd like to create this in T-SQL but can also do it in VB.Net. This number will be stored in SQL and I can access it prior to generating the next one. They do not have to be sequential.
I am trying to populate an array with all the unique values in a string, to prevent me ReDim'ing an array every time I find a value that not already contained in the array I am trying to create (consumes alot of time), I am trying to get the unique values first so I only have to ReDim once and after that I can simply iterate through the string and the array I have will be the correct size for the unique values I aquire (I am using this...)
