代码从API guide上copy的
第一个问题，要先定义OSVERSIONINFO
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

'Set the graphical mode to persistent
Me.AutoRedraw = True
'Set the structure size
OSInfo.dwOSVersionInfoSize = Len(OSInfo)
'Get the Windows version
Ret& = GetVersionEx(OSInfo)
'Chack for errors
If Ret& = 0 Then MsgBox "Error Getting Version Information": Exit Sub
'Print the information to the form
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第二个问题是没有问题。
