You can always use WMI... WMI can query just about any system information.

There maybe an easier way, but WMI is probably the most comprehensive.

How do I query WMI for Operating system type?

Here's the reference for WMI:

http://msdn.microsoft.com/library/default.asp?url=/library/en-
us/wmisdk/wmi/wmi_reference.asp

Sample on using WMI with Vb.NET:
http://www.freevbcode.com/ShowCode.asp?ID=4571

WMI is pretty neat... you can query WMI via .NET like a SQL database. The
trickiest part with WMI is to find the proper object to query.

You might want to try the class Win32_ComputerSystemProduct. I think the
info your looking for maybe in there:

us/wmisdk/wmi/win32_computersystemproduct.asp

Thank Lucas, I did query the WMI I used the following attributes:

"name" for ComputerName
"version"
"csname" Operating system name
"systemtype"
...
I ran it on my desktop as well as my tablet PC....

Unfortunatly none of these tell me about Tablet PC. The OS name for tablet
PC and regular Desktop is reported as Windows XP. I am not sure which
attributes (if any) contains info about tablet PC.

Thanks again for the help.

some reason wont work for me.

Untested:

Maybe 'Environment.OSVersion' provides enough information for your
needs.

Try copy and pasting the links manually. The links run onto two lines.

In both system it reported as WIndows NT and nothing about Tablet PC.

OK, I could not check that without a tablet PC .

Just a thought: Why not install the mondo patch which will prevent OE
from breaking long links?

Al,
According to the Microsoft Tablet PC SDK:

<quote>
Q. How can I determine if my application is running on a Tablet PC?
A. Use the Windows GetSystemMetrics API and pass in SM_TABLETPC as the value
of the index. SM_TABLETPC is defined in Winuser.h. The value of SM_TABLETPC
is 86. The method returns True or nonzero if the Microsoft Windows XP Tablet
PC Edition operating system is running; False or zero otherwise.

Applications should not rely on a true or nonzero value to mean all Tablet
PC components are installed and working. See the following question for
details on how to determine if Tablet PC components are installed.

</quote>

I would expect System.Windows.Forms.SystemInformation would list the value
as it gives most other SystemMetrics, however it appears to be missing
TabletPC (SM_TABLETPC).

You can use code similar to:

Public Enum SystemMetric As Integer
TabletPC = 86
End Enum

Declare Auto Function GetSystemMetrics Lib "User32" (ByVal index As
SystemMetric) As Integer

If GetSystemMetrics(SystemMetric.TabletPC) <> 0 Then
Debug.WriteLine("On a Tablet PC")
Else
Debug.WriteLine("Not on a Tablet PC")
End If

Hope this helps
Jay

Hi,

Looked in the Tablet PC SDK. Says to use GetSystemMetrics API to
determine if program is running on a tabletpc.

Declare Function GetSystemMetrics Lib "user32" Alias "GetSystemMetrics" _

(ByVal nIndex As Integer) As Integer

Private Const SM_TABLETPC As Integer = 86



If GetSystemMetrics(SM_TABLETPC) <> 0 Then

MessageBox.Show("Tablet PC")

Else

MessageBox.Show("Non Tablet")

End If
