Converting HDD Serial # VB6 code into VB.NET code

Question

I\'ve got a cool piece of code taken from a VC++ project which gets complete information of the hard disk drive WITHOUT using WMI (since WMI has got its own problems) I ask

Answer 1

Sorry I don't have time to convert it for you, but if nobody else comes up with the code, you could do worse than take a look at http://www.pinvoke.net. Your VB6 code has to call Windows API functions to do the work, and VB.NET code has to do the same. It will call the same API functions.

For example, here is the page for DeviceIoControl.

But if you wait long enough, somebody else might just have the code to hand :-)

Answer 2

That's a lot of code to wade through for someone who doesn't understand the spoken language used in the comments.

I will says this: Anywhere in that code you see the Type keyword you probably want to use Structure instead, the syntax used for Properties in .Net is a little different, function calls require parentheses, and VB.Net doesn't have an 'Any' type (maybe System.IntPtr instead? not sure).

Most of the rest of the syntax in VB.Net is the same, and so you might have better luck making the fixes I've already mentioned and then addressing each error (or type of error) you get when building the resulting code individually.

Answer 3

I found it! Here is the equivalent VB.NET code. It's not exactly the converted version of the VB6 code, but does the same thing. Enjoy!

Answer 4

You can get this data of WMI. Let me get you an example

Answer 5

Try
Dim Searcher_P As New ManagementObjectSearcher("root\CIMV2", "SELECT * FROM Win32_PhysicalMedia")
For Each queryObj As ManagementObject In Searcher_P.Get()
If queryObj("SerialNumber").ToString.Trim = "Y2S0RKFE" Then
Me.Cursor = Cursors.Default
Return True
End If
Next
Catch ex As Exception
MessageBox.Show("An error occurred while querying for WMI data: Win32_PhysicalMedia " & ex.Message)
End Try

Try
Dim Searcher_L As New ManagementObjectSearcher("root\CIMV2", "SELECT * FROM Win32_LogicalDisk WHERE DeviceID = 'C:'")
For Each queryObj As ManagementObject In Searcher_L.Get()
If queryObj("VolumeSerialNumber").ToString.Trim = "226C1A0B" Then
Me.Cursor = Cursors.Default
Return True
End If
Next
Catch ex As Exception
MessageBox.Show("An error occurred while querying for WMI data: VolumeSerialNumber " & ex.Message)
Return False
End Try

Answer 6

Yeah, I know VB6 but the problem is with the API function declarations and the attributes required to pass those structures (types) to them. That's where I don't have the time to spend! If you have an automated VB6 to VB.NET tool and VB6 itself, please save the code as a VB6 project and do convert the code. I don't have my VB6 around.
