dotnet distributed apps : Software Protection

Is there any way to get the CPU serial, MAC address, and Volumn ID from
VB.Net? I am thinking to make use of the information to generate serial
number request code. The serial number request code then can be used to
generate final serial number to provide the the use for activate the
software we distribute.

Thanks,

Tony,

Here are some ideas:

MAC Address: System.Net.NetworkInformation.GetPhysicalAddress
Volume ID: Call the Win 32 API GetVolumeInformationA function in
the kernel32 dll
CPU serial: See this thread for ideas

Hi Carsten,

Can you show me this buy writing a sample code to show how to get the MAC
address? I am new to OOP and Dot.NET.

Thanks!

GetVolumeInformation does not get the drive serial #, it gets the volume
serial #; which is not fixed and there can be more than one volume per drive.

Getting the physical disk's serial number is somewhat complicated and can be
done through WMI. See http://www.codeproject.com/csharp/logicaldiskinfo.asp
for an example in C#.
