Dim os As OSVERSIONINFO ' receives version information Dim retval As Integer ' return value 0=error occurred, 1=successful
os.dwOSVersionInfoSize = 148 ' calculated size of the OSVERSIONINFO type retval = GetVersionEx(os) ' read Windows's version information
'sample of ouput Note "Windows version number: "+ str$(os.dwMajorVersion)+ "."+str$(os.dwMinorVersion) +chr$(10)+os.szCSDVersion |
