I want to protect the Software by making it to ask for a Activation Key when the software is installed in a computer - I have seen commercial programs asking for Activation Key and for this I should send a Number shown after installing the software in the Computer.I want to know how to make this in a program. Can anyone give the Code and etc for MS Visual Basic 2005.
View 1 RepliesHow do I save the information from each activation of the code inside the loop. I decided to try this a different way. I also need to know how to create colums in a label?
For countInteger As Integer = 0 To 3
seatsSoldInteger = ticketDetail(countInteger).seatsSoldInteger
costDecimal = ticketDetail(countInteger).costDecimal
totalTicketSalesDecimal = ticketDetail(countInteger).totalCostDecimal

I have Visual Basic 2005. I want to be able to adjust the Master Volume programmatically. In the recent versions of Visual Basic it is much easier but in VB2005 it is a little more involved from what I have read on previous posts. Is there a way to adjust the volume in the code of a Visual Basic 2005 program?

View 1 RepliesJust 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.
View 6 Repliesi have installed my program on several computers and it works but for some reason on this one computer it doesn't work.i attached the error log. i can't figure out why it won't run. it installs ok.
View 6 RepliesLet'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 devices with unique serial number (string incremetation) ex : AS1002 and AS1003. I need to figure out an algorithm to produce a unique activation key for each serial number. What would be the best approach for this ?
View 5 RepliesI 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.

View 1 RepliesI 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.
View 5 RepliesI 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?
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")

View 23 RepliesIt's being some years since i actually wrote a program in VB, last time was VB 6.So it's being a long time, and things have changed a bit.And i am still very rusty, so i need to get back into it.I got a few problems which i cant remember very well.1st question.I got several text boxes, in these text boxes there will be prices of products.The very last text box is inactive, and is supposed to show the total of all of the above.I have to declare the text boxes to contain numeric values only, so there will be no mistake when doing the calculations.But i cant remember what it was, and what the best option is to add up all the values from the text boxes.
