vb.net读取版本号 VB的版本
vb做的软件如何获得自己的版本号?
如果你用的是vb6,而且指的是你在编译程序的时候写的版本号,比如1.0.1可以用app的属性得到

MsgBox App.Major "." App.Minor "." App.Revision
其中major是主版本,minor是次版本,revision是修正
在.net中会比较麻烦点,参考下面
Type FileInfo
wLength As Integer
wValueLength As Integer
szKey As String * 16
dwSignature As Long
dwStrucVersion As Long
dwFileVersionMS As Long
dwFileVersionLS As Long
End Type
' NOTE: The following Declare statements are case sensitive.
Declare Function GetFileVersionInfo Lib "Version" _
Alias "GetFileVersionInfoA" (ByVal FileName$, _
ByVal dwHandle, ByVal cbBuff, ByVal lpvData$)
Declare Function GetFileVersionInfoSize Lib "Version" Alias _
"GetFileVersionInfoSizeA" (ByVal FileName$, dwHandle)
Declare Sub hmemcpy Lib "Kernel32" Alias "RtlMoveMemory" _
(hpvDest As Any, hpvSource As Any, ByVal cbBytes)
Function LOWORD(x As Long) As Integer
LOWORD = x And HFFFF
' Low 16 bits contain Minor revision number.
End Function
Function HIWORD(x As Long) As Integer
HIWORD = x \ HFFFF
' High 16 bits contain Major revision number.
End Function
'----------------------------------------
'以下为执行模块,在 VBE 界面按 F5 执行
'----------------------------------------
Function displayVersion()
Dim x As FileInfo
Dim FileVer As String
Dim FileName As String
Dim dwHandle, BufSize, lpvData$, R
'*** Get Version Information If Available ****
FileVer = ""
'FileName = 路径
FileName = Environ("windir") "\system32\msjet40.dll"
BufSize = GetFileVersionInfoSize(FileName, dwHandle)
If BufSize = 0 Then
MsgBox "Invalid File Name or no Version information available"
Exit Function
End If
lpvData$ = Space$(BufSize)
R = GetFileVersionInfo(FileName, dwHandle, BufSize, lpvData$)
hmemcpy x, ByVal lpvData$, Len(x)
'**** Parse File Version Number ****
FileVer = Trim$(Str$(HIWORD(x.dwFileVersionMS))) + "."
FileVer = FileVer + Trim$(Str$(LOWORD(x.dwFileVersionMS))) + "."
FileVer = FileVer + Trim$(Str$(HIWORD(x.dwFileVersionLS))) + "."
FileVer = FileVer + Trim$(Str$(LOWORD(x.dwFileVersionLS)))
MsgBox FileVer, 64, "Version of " FileName
End Function

VB.NET 注册表读取
VB.NET主要是利用RegistryKey类封装的方法、属性等来进行与注册表相关的各种操作。
请参阅RegistryKey类
Imports Microsoft.Win32
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim a As String = Registry.CurrentUser.GetSubKeyNames("")
End Sub
End Class
需要 Microsoft.Win32命名空间。
