View 8 RepliesVS 2008 License Check
Sep 13, 2010The 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.

View 7 RepliesDatagrid Displays Fine But INSERT, DELETE And UPDATE Don't Work
Oct 28, 2009I have created a test application to display data in a datagrid, using the Dataset Wizard per the help. All fine - data is displayed.
I then added insert, delete and update queries by selecting Edit Dataset with Designer, selecting the table and adding a query for each action via the TableAdapter Configuration Wizard. In Advanced Options, all boxes are checked, and on the last screen of the wizard it says it has generated SELECT, INSERT, UPDATE, DELETE statements, table mappings, Fill, Get and update methods. The TableAdapter shows four entries: Fill, GetData(); DeleteQuery; InsertQuery; UpdateQuery. On the DataGridView Tasks page, Adding, Editing and Deleting are checked and the data preview shows data.
When I run the application, I can update, add and delete data, but this is not saved.

Set Up A License That Expires?
Jun 19, 2009We 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.

View 3 RepliesLicense Key System For Application
Mar 19, 2012I 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?

Secure Way To License Software?
Aug 13, 2009What 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.

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?

Apr 24, 2010I want to create a license key function for my application.

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.
