VS 2008 License Check
Sep 13, 2010
The issue, is that I'm developing an app that won't be installed and will be used on a bunch of different PCs. The app is free, but uses some 3rd party tools and code, so the user must be aware of the licensing agreement for those tools.
Since it will be used on a bunch of PCs, I don't want the end user to have to accept this license agreement a million times.
Is there any way I accomplish this with a local resource of some sort?I was thinking I could add a license file that should be moved around with the executable, and that could contain a license agreement code, then i could prevent the app from being used without that file.

Just looking at various ways to do so.I came accross an article which unfortunatly I can't find anymore. It explained it like this. (I'll try remember all of it)1) Put activation key in textbox12) Press button3) Checks with the FTP server if the title of a file (In the this case the license key) in the FTP server.4) If the file doesnt exist then a message box comes up incorrect license.4b) I the file does exist then my.settings.activate = 15) Next time its loaded up, the program checks if my.settings.activate = 15b) If not then an activation key must be put in and proccess starts again.

My vb.net browser will be the first application I'm actually pushing out to the public.Everything else so far was for me and friends or some type of class. My problem is I don't know what license to pick to release it under. It's going to be partially open source and partially not.Whats included that i didn't write or make
GeckoFx - web browser plugin like ie but based off firefox
App Life Update - http:www.kineticju...te/Default.aspx ( I have the free limited license)
Sqlite - used for bookmarks
Other than those to plugins/dll files everything else i wrote myself or followed tutorials on and modified to fit my applications need.

We plan on selling an application that I've made and we want to be able to force the user to buy a 1-year license for it. And of course after that 1-year we want the program to stop working and force the user to purchase another license.
I've seen many things in VB.NET with certificates/licensing but I'm just not familiar with them to be able to take it any further. And right now I don't have the labor to spend hours messing around with it.

I have a problem with my application. I have got it to the point of running the AVG installer, but it fails because a licence key is needed. I have the licence key, but the idea is that my application makes it easy for the user by them just needing to click through.
Is there a way to automatically input the licence key into the licence key field on AVG's set-up from my application? [code]...

I have built an excellent licensing key system which works well on desktop pc's. Basically I run an algorythm on the Hard Disk Serial Number and the Customer Name. While this is not totally brilliant, it seems to work really well (on desktop machines or machines with real hard disks). Now that we come to Tablet PC's, I have found that the Serial Number of the "DISK" which is normallyan SSD is the same from one machine to the next - so all unlock codes end up the same. How about making a unique code for each machine I install my application on?

What is the best and most secure way to license software? Is there an existing program for doing so? I want to sell a script of mine, but I want to make sure that users cannot redistribute or sell it themselves (of course, if they deactivate the registration on their own computer and choose to resell, that is their choice).
The software language is VB.net.
Since I am not sure whether or not I could host a registration database of any sort, is there any way to keep licensing self-contained securely? I would like the user to be able to download the demo and be able to upgrade to the full version somehow.

I have an application that will be sold to a verticle market. Our techs will do the install, and the software requires hardware for it to work. But I still need to create something so that each customer has a key to use the software. So what is the best way to approach this. I don't high security, because the softare won't do a customer any good without hardware. But it's required in the bids that we do. I also have diffrent options for the software. Not everybody wan't all the bells and whistles, just the basic pakage.I was thinking maybe using a dongel for hardware key? But that more cost.Your thoughts?

I want to create a license key function for my application.
For example I want in this key to contact 2 values: registered_to, expiry_date.
I want the licence key to be some sort of large string like: 2349ASDGKLASD87ASDGALSDK8ASD80972K.
I would need to create some way to create keys use some sort of algorhithm that decrypts the key and grabs the registered_to and expiry_date values. It also needs to check that the key string has some sort of check digit like credit cards have, so no-one can just type in a few random letters/numbers and it accepts.

When a user activates my program, a license file is emailed to them as an attachment. Some people are having trouble saving/downloading email attachments so would it be possible for the program to download the license file during activation into the installation directory?
During activation my program connects to my website and checks the user is registered and if so a license file is created online and emailed to the user[code]...
