Product Activation And Licensing...is It Worth The Effort?
Apr 30, 2012
I have created an Excel Ribbon Addin that has some custom features that will benefit a relatively small business niche. The target companies number less than 1,000.I don't want to limit any one company's usage of the Addin...meaning I want them to be able to install and use the Addin as often as they need to, for as long as they need to, on as many computers as they need to.
The thing I want to prevent is sharing of the Addin. There are family members in this industry, that own different companies in different parts of the country...there are close friends in this industry that each own different companies. I want each company to purchase the Addin instead of share it.I have created a License Agreement that they have to agree to before the Addin is installed. But, that is as far as I have gone with it at this point.So, this leads me to 2 questions:
1. Is it worth the investment and effort to create this type of limitation for such a small market?
2. If so, what is the best way to go about accomplishing this?

I have 2 datagrids. One to show Product information and another for Product purchase details entry. Both share the same dataset. The dataset (ds) is filled up with columns from 2 table
ProductMstrTbl : ProductID, ProductName..
ProductDetailsTbl: ProductID, PurchaseDate, Amt, BalanceQty..
DataSet(ds) : ProductID, ProductName, PurchaseDate, Amt, BalanceQty.
The problem is that: Showing from dataset or entering new records into the dataset is no problem, but am not able to save the modified dataset into DataBase. SqlCommandBuilder failed to generate the corresponding INSERT, UPDATE command as the dataset has multiple base tables.

I am looking for a free utility or way to protect my software by requiring a Product ID (Which will be created when a customer requests a paid license) to use the application after a demo version. Like most shareware apps.

I am making a solid effort to upconvert myself from VB6 to VB 2008 Professional. My current issue is with querying and updating to SQL 2008 Express. In VB6 this was a simple matter of adding an ADODC to the form and creating set queries in DataEnvironment that you reference in the code.Now, I don't suppose there is anything like that method in VB2008 (if I'm wrong and there is, then yippee!) so if possible I'd like a link to a straightforward methodology of querying and updating data in a SQL Database.
Please note, I am not yet down with alot of the abbreviated code references that generally gets used in VB2008 for dealing with SQL connectivity.

I am new to vb-net and am self-teaching and developing an application to combine a number of tasks which use different apps at the moment. I have a routine to ftp upload files but I am duplicating effort by uploading even if the file exists. Is there a simple "file exists()" type solution similar to:
If System.IO.File.Exists(strPic) = True Then so that file is only uploaded if it does not already exist?

I agree that the best way to shorten the ViewState is to disable it on the ASP.Net controls that don't need it. Keeping it small from the beginning is a great habit.I have also heard that it is already compressed (although can be true... there are ways of compressing it even more, has described in this Stack Overflow question).
My question here is not if it should be compressed... is: when should ViewState be compressed?If we have a ViewState of 410 characters it will weight 410 bytes in a page, while a ViewState of 13.843 characters equals 13.5 KB.
13.5KB is a considerable weight already. And if I compress a CSS file that height 10KB, I think it is also worthy compressing a ViewState of 13.5KB, even if that means a little extra "thinking" on the server.
But is 410 bytes of ViewState worth the extra processing on the server?At what point is it worth compressing?

I need to download serveral years worth of files from a web site, the web site posts files daily in "Date".csv. How do I write the code in vb.net to get the string value for the dates? I know that you can do something like : Dim start date = #11/01/2009# and Dim end date= Now.
How do I get these values so I can incorportate them in a string? And then loop through each value.
It will need to start with the first date an download that file, then loop through all the dates downloading each file until it has reached the end date. I already have the code written to extract the info i need from the document and import into a sql server, my only issue is the date range string issue

Coming form too many years of VB6 I have a natural inclination to write my own data access code, etc. rather than using database wizard, etc. Same goes for using simple databinding to recordset rather than managing object collections and tying those to controls
I am finally moving to VB.NET and find myself on a solo project without any team on which to lean, so I have a couple related questions as I try to get my head around the transition. The project is basically a line of business app with a SQL Server back end.
1. Are the data designers/wizards so good now that rolling your own is no longer worth while?
2. Is the data-binding now fast, flexible, and reliable?
3. Can you recommend a good book or robust on-line tutorial that covers this sort of programming? 2008 or 2010 preferred.

I have a vb program that is closed source free program. I am using a CONSOLE PROGRAM licensed under the GPL license. This is not GPL source code, but an actual GPL app.(I am using process.start to run it) and I was wondering if there is a licensing incompatibility or something. I am clueless on licensing. Would I just have to include a license file with it, or would I have to release the code, or what.

I installed my old Visual Basic programmes in Windows 7 and I have two problems.
1- VB itself which apparently is not compatible.
2- I used some controls which are not supported anymore but I used vbusc.exe for Windows XP and it worked. Now for Win7 what can I do?

I have up until recently developed only in-house custom applications and I have never had a need to protect this software with any type of licensing/ protection mechanisms.I'm now working on a new project for a software app that I plan on distributing to a relatively small number of clients (1000 or so) and I need to consider some type of licensing/software protection solution that I can easily integrate into my application.I'm also looking for specific product recommendations (if possible) based on users experiences. With vast assortment of product offerings out there, I'm having a very hard time wading through them all.
I would like to stick with a software option over a hardware dongle type solutions so that I can make distribution and activation as painless as possible for my customers¦but would consider hardware options if need be.I have tried the KeyLOK hardware evaluation kit but it seems to be a little difficult to implement and it would force my customers to wait days before they could initially activate and use my application. [code] License registration and tracking via Internet..Software distribution is very controlled and it's not a techie type user audience, so hacking is not a major concern but I would like to protect the application as much as possible.

I need to reformat my HD and will lose everything, including my VB stuff. I can't positively identify all of it's contents/shared folders/assciated files, etc so as to back it all up. I would like to know how difficult will it be to simply reinstall all of the software from MS, concerning the registration/licensing/activation process? Or will I just have to start w/a new copy/registration/licensing ,etc? By the way, I am talking about "Express Editions"

I�m trying to implement a licensing schema for a template that uses the follow code snippet. (using VS2010 vb.net4)
<LicenseProviderAttribute(GetType(RegistryLicenseProviderSave)), _
GuidAttribute("2de915e1-df71-3443-9f4d-32259c92ced2")> _
Public Class Form1main
��. Form code etc.
End Class
I need to utilize the GUID value in other classes within my application, as an example, as making registry entries.My goal is to have this editable at only 1 place in the template.I�ve created a Friend class that has the GUID string in it, but I�m unable to get the above to recognize the string. I�m sure that the code is simple, but it evades me.I would really like to do is to access the Guid that VS2010 vb.net creates (Project->Application->Assembly) shows and insert it into my application.

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.

Let's say we have a controltab with two tab. The first tab contains textboxs where entry values are entered On the second tab are textboxs that display the results. I have noticed that if I fill up the entry values and create the binding between each textbox and their property and then I destroy it (without clearing the textboxs), the textboxs of the second tab will not display any result. I have this exemple here BindingAddition.rar

An application I'm working with registersun-registers a group of dll's using regsvr32.
System.Diagnostics.Process.Start("regsvr32", "somedll.dll /s")
This worked fine on Pre Vista systems but this will not work on Vista7 due to UAC.
Is there an alternative method to register dll's programatically without needing elevation?
If it help's the dll only needs to be registered for the current user, could adding details to the registry directly solve this?
(The application runs several versions of a legacy application, these dll's are swapped out depending on the version being loaded)

I have made some custom .dll's or components and then I downloaded custom webkit component and it didn't work perfectly(I mean that I always get some error code with this error: An error occurred creating the form. See Exception.InnerException for details.The error is: Failed to initialize activation context. When I try to debug the project). And if I have made a new project, and make a component with user control, and I haven't saved it yet, it will work fine, but until I save it then it will give me a designer error.

I am going to publish my program soon. As for the product serial activation, I have combined the user machine's CPU ID and the MAC Address to make a formula. Here is the class code to find processor ID and MAC which I have found on net and used :
Friend Function GetProcessorId() As String
Dim strProcessorId As String = String.Empty
Dim query As New SelectQuery("Win32_processor")
Dim search As New ManagementObjectSearcher(query)
Dim info As ManagementObject
[Code] .....
There a few questions I want to ask to be sure about my program activation :
- These 2 function code, Are they safe to use ? Is there any possibility that one of them or both doesn't return anything ? ( because of user permissions,os type, etc...)
- Is it possible that somehow the user machine won't have MAC Address?
- Is Proccessor ID a Unique serial for each machine in the world?

In Excel 2010 (but also in older versions you can find a nice functionality - auto filter. When you just put some data in a row and press CTRL+SHIFT+L you activate Auto Filter. Now you press the down arrow and you get what I need... A new window appears. This window include buttons ordered in something like a context menu a textbox and a checkedlistbox. The windows definitely is not a classic form, because when you operate with the controls on it, the original excel windows is still the active window. The window can also be drawn outside of the main excel windows.

This is how I handle online activation for my application the problem is that this is very poor security because i display my Username and Password. I was thinking of using Myslq but i also have to input the Username and the password into the application. What other ways do big companies like Kaspersky handle online activation.
My code
Try
My.Computer.Network.DownloadFile("FTP SITE" + textbox1.Text + ".txt", "C:" + textbox1.Text + ".txt", "USER", "PASS")
Dim auth As String = My.Computer.FileSystem.ReadAllText("C:" + textbox1.Text + ".txt")
If auth = Textbox2.Text Then
Kill("C:" + textbox1.Text + ".txt")

costDecimal = ticketDetail(countInteger).costDecimal
totalTicketSalesDecimal = ticketDetail(countInteger).totalCostDecimal
