RE:Como distinguir los Windows??
Fijate con esto:
Private Declare Function GetVersionEx Lib "kernel32" Alias "GetVersionExA" (lpVersionInformation As OSVERSIONINFO) As Long
Private Type OSVERSIONINFO
dwOSVersionInfoSize As Long
dwMajorVersion As Long
dwMinorVersion As Long
dwBuildNumber As Long
dwPlatformId As Long
szCSDVersion As String * 128
End Type
Private Sub Form_Load()
Dim OSInfo As OSVERSIONINFO, PId As String
OSInfo.dwOSVersionInfoSize = Len(OSInfo)
Ret& = GetVersionEx(OSInfo)
If Ret& = 0 Then MsgBox "No se pudo obtener la versión actual": Exit Sub
Select Case OSInfo.dwPlatformId
Case 0
PId = "Windows 32s "
Case 1
PId = "Windows 95/98"
Case 2
PId = "Windows NT "
End Select
Print "OS: " + PId
Print "Win version:" + str$(OSInfo.dwMajorVersion) + "." + LTrim(str(OSInfo.dwMinorVersion))
Print "Build: " + str(OSInfo.dwBuildNumber)
End Sub
