hi all,
I have made a s/w in vb 6 and i want that it should not be pirated.For sake of this what i am thinking to do, once s/w is installed ok, than at first run (.exe) it will generate a unique username and client will tell me that username and i give a password dependent on that user name.Once the correct password is entered s/w will save this in someway so that s/w wont ask for password again as the client is been authenticated by me.
example:
username:AXUQOH 271RQOP
password:(Anyth ing)
What i do to check for the authentication at back end , i change a boolean variable to true and i give password to that access data base.
I want to know that what are the possible breaches(threat s) ???
or if you have better solution than please give me...
Thnax...

See we can't directly stop the piracy as if i authenticate any s/w to any user and if he sold his hdd to some one else then.........
but apart that we can restict unauthenticated user by registering key
this is the best method which don't need backend to store the value
to protect hdd problem u may try doongle
I have seen this kind of authentication in a software.
1. When you install software, a 10 digit dynamic key is produced.
2. Client has to call his vendor with this key and his id.
3. A serial no can be produced based on this key and client id. (this is separate program and not given to client)
sounds silly. isnt it ? But very strong.
(may be no one will buy software, perhaps)
Or you can do this ->
1. Generate a dynamic key ( Input is client id ) with your own algorithm. (This is separate program and not given to client )
2. Give that key to application while installation.
3. When program starts up, it compares client id and key. If it matches, application is opened.

hi baskarpr,
the first method is same as what have i written.
but in second method where to store the generated key and i dont get how the exact procedure plz enlighten it ..
thanx...
How many users do you anticipate buying your software?
What is the market value of your software?

I think you can try like this..
1. Receive the random generated id (while installation) and client id from mail.
2. Generate the serial key with these two inputs.
3. Send back through mail.
You should decide whether it is automatic or manual, i.e. receiving random id, client id and generating serial key.

Hi,
I have two windows services running together. One is the main

service starts and stops the main one (as in you should never start or
stop main service manually, only updater).
On most computers it works great, the updater's onStop() can start and
stop the main service perfectly. On some computers, though, the
updater hangs when it tries to stop the main service. It...
