I develop a MapInfo-based GIS and I need to be able to determine the Windows OS of a given user. So far we have used a Windows function GetVersionEx (kernel32 library) to do this but the function doesn't behave properly from Windows 8.1 onwards...unless you do Application Manifesting which I'd rather not mess around with unless absolutely necessary.

As an alternative I found a post suggesting to use GetProductInfo instead but I don't know how to set this up in MapBasic.

The GetVersionEx function is first defined like this:

    dwOSVersionInfoSize As integer
    dwMajorVersion As integer
    dwMinorVersion As integer
    dwBuildNumber As integer
    dwPlatformId As integer
    szCSDVersion As String * 128
End Type

Declare Function GetVersionEx Lib "kernel32" Alias "GetVersionExA"
    (lpVersionInformation As OSVERSIONINFO) As integer

(OSVersionInfo documentation here)

And then called in MapBasic:

Dim OSInfo as OSVersionInfo
Dim nRet,iMaj_Version As Integer

'Set the structure size
OSInfo.dwOSVersionInfoSize = 148    'Len(OSInfo)

'Get the Windows version
iRet = GetVersionEx(OSInfo)

'get values e.g.:
iMaj_Version = OSInfo.dwMajorVersion

so it will be similar to this I expect...but I don't know how the new function needs to be defined or how I then get the output in to a MapBasic variable.

Finally, we are using the 32-bit version of MapInfo so for the time being I'm not interested in potential help/solutions for the 64-bit version.


I have successfully implemented this solution.

enter image description here

Based on that I have created .NET assembly (*.dll).

After that all you need is to declare the method in your MapBasic application:

Declare Method OSName
    Class "nmiDotNet.MBOSinfo" 
    Lib "nmiDotNet.dll" () As String    

And you can call this method like simple function in MapBasic: OSName()

I customized output string to get names like this:

Windows 10 Professional Bit64 
Windows 8 Professional Bit64 
Windows 7 Enterprise Bit64 (Service Pack 1)
Windows 7 Enterprise Bit32 (Service Pack 1)
Windows XP Professional Bit32 (Service Pack 3)
