Use RSA To Encrypt Application Serial Number?
Jun 11, 2012
I'd like to use RSA to Encrypt application Serial Number.
but when you try to encrypt text and did it again both time the results will be different i don't like to decrypt to text to protect the application from hackers. any other useful way to protect the application without Decrypt to text.
i mean compare Encrypted code not the original text also i need to stop application if there is crackers application starts or memory dump application or memory injection .
i need the full solution to protect the application . i wish the armadillo (software Passport ) is here for vb.net application how great it is ... i miss him may be we start discussion about protect application . also what about encrypt all application code to disable resource hacker applications .

I have an application I have developed which works great on individual PC's. However I've had some interest from a few customers that asked if I have a network version for site licencing.If my app did not save any data or write any reg entries, this might have been ok. But it does to the local computer. I also built in my own copy protection and trial function that stores data in the registry on the local computer.What would I need to do to enable my application to run on a server/network share, so that the only a serial number needed is for the server?

I made my program and now I just need to add in the serial and trial part of the application. I know the application must connect to the host and go to a txtfile. How would i do the trial and serial. Also If the serial is already activated I want the application to reject that Serial and Count how many times they entered in a wrong serial.

I am making my first application which involves WMI.. Using the documentation provided by MSDN and the Forums I have managed to get data related to the Win32 Class (Computer Name, Physical Memory, IP Address, etc..) Now I would like to get the Serial number of the monitor. I believe I have to use the WmiMonitorID Class. However, I do not know the Syntax to access the property of the same. I had used the code below for the win32 class. How do I modify it for the WmiMonitorID Class?
Public Function OpSys() As String()
Dim Str(4) As String
' ManagementObjectSearcher retrieves a collection of WMI objects based on[code]........

OS: windows 7 64-bit /Programming Language: Visual Basic.net on Visual Studio 2010 express edition.I have dataset with 4 tables each one of them is a datasource to a datagridview I want to add a serial number column to the datagridview so I made this
DataGridView1.Columns.Add("serial", "SER.")
For x As Integer = 0 To (ds.Tables("workers").Rows.Count - 1)
DataGridView1("serial", x).Value = (x + 1)
Next
It was working fine untill I added a relationship to the dataset the relationships codes were
Dim relation_WC As New DataRelation("relation_WC", ds.Tables("workers").Columns("id"), ds.Tables("cources_jun").Columns("workerid"))
Dim relation_WV As New DataRelation("relation_WV", ds.Tables("workers").Columns("id"), ds.Tables("vacations_jun").Columns("workerid"))
[code]....
I breaked point the debuging and I found that the serial number column I added is fine and has it's values, but when I reach the line relations.add(the_relation) the serial number column loses it's values and turn into an empty column with no
numbers in it....why this is happening?
Note: I added another relations but the only relations that clear the serial number column are the relations that has a datatable that is a datasource to the datagridview that has the serial number column.
