View 8 RepliesI recently purchased Visual Studio 2010 and am wondering if it is possible to use the VS2010 license as a substitute for VB6 license.
View 2 RepliesIn a VS2010 solution I have a license.licx file that contains:
DataDynamics.ActiveReports.ActiveReport, ActiveReports6, Version=6.1.2814.0, Culture=neutral, PublicKeyToken=cc4967777c49a3ff
DataDynamics.ActiveReports.Web.WebViewer, ActiveReports.Web, Version=6.1.2814.0, Culture=neutral, PublicKeyToken=cc4967777c49a3ff
DataDynamics.ActiveReports.Export.Pdf.PdfExport, ActiveReports.PdfExport, Version=6.1.2814.0, Culture=neutral,
[code]....
If I build the solution on a machine that HAS a license for ActiveReport then everything is fine. If I build the solution on a machine that DOESN'T have a license for ActiveReport I get:
Error 1 'Could not load file or assembly 'ActiveReports6,
Version=6.1.2814.0, Culture=neutral, PublicKeyToken=cc4967777c49a3ff'
or one of its dependencies. Operation is not supported. (Exception
from HRESULT: 0x80131515)' LC
On the machine that DOESN'T have a license for ActiveReport if I remove the above lines from the license.licx file then everything builds fine. I always thought that if the license couldn't be found then the unlicensed version will be used but it wouldn't kill the build. How do I get this solution to build on any machine whether it has a license or doesn't?
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?

View 4 RepliesI'm currently generating some excel files using vb.net (2008). I want to protect the workbook or sheet inside, so that the user cannot edit anything within the file.I tried some options from MSDN but no luck and some other forums but no luck.The following is my last few lines of code in the program.
Code:
ExcelReport = New Excel.ApplicationClass
ExcelReport.Workbooks(1).SaveAs(ExcelFileName)
I basically don't want the user to edit anything inside the file. Perhaps a printout is allowed.
I have a form. And some controls(such as TextBox,ComboBox,etc.) on the form.Now,I want to store the controls' Text into a .txt file(or any other formarts).Then I want to read the text in the .txt file to my controls.

I am trying to create a log file which I am going to use to populate some controls (DataGridView or Treeview). I am trying to figure out if should use text files or XML files to do so. Effectively the log will highlight multiple phases in a client-side app. The log will be written to at various phases when the project is running. The user will always have the options move on to the next phase or save progress and exit the project. As such, I want the log file to highlight how far the user has progressed throught the various phases AND I want the log to highlight varous information from each phase. Whenever the user starts the project, they will be given the option to load existing log files. So the project will have to read these log files and append them where necessary as the user progresses.
I am not sure what the best way to do this is and below is a rudimentary approach using text files. As you can see, the top of the file would have a summary of all the phases and whether or not the user completed each phase. Next each phase would have a data section highlighting what data was stored along the way. I have used a ":" to denote each section. Then within each section I would obviously need to use a delimeter for all my data. So if Phase1 = True, then I would load all the pertinent data from "Phase1:" into the desired control. Can anyone provide an efficient way of doing this and provide some insight as to whether I should use XML instead. The phases my change during development and I am not sure yet which controls I will be using. Does XML provide more flexibility.
In summary I am looking to create, read/write and append log files and populate controls with the data in varous sections of the log file. Example:
Phase1 = True
Phase2 = True
Phase3 = False
Phase4 = False

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.

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.

View 3 RepliesI 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?
View 1 RepliesI am wondering how to make a product key as a license key for my VB.Net windows form application? Because at the end of the day, i would have to package it as a exe file and i would like to include in a license key for the user.
And also may i know how to package the whole project as a exe file such that after the user excute the installer, everything will run. like how you install windows xp like that.
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?
View 5 RepliesThe 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.
After countless hours of production, I've finally got a working product that I'd like to market. However, I obviously don't want this product stolen and torrented.

View 13 RepliesI 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.
