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。

vb.net 应用程序怎么获取自己的版本号

Try

Me.Text = "版本V" Deployment.Application.ApplicationDeployment.CurrentDeployment.CurrentVersion.ToString()

Catch ex As Exception

Me.Text = "未知版本"

End Try

vb获取硬件信息的代码

tmpstr=""

set fso=createObject("scripting.filesystemObject")

Set dc = fso.Drives

for each d in dc

If d.isReady Then

tmpstr=tmpstr "磁盘" d.DriveLetter ":" vbcrlf _

"可用空间：" (d.AvailableSpace/1024/1024/1024) " GB" vbcrlf _

"空余空间：" (d.FreeSpace/1024/1024/1024) " GB"  vbcrlf _

"总空间大小：" (d.TotalSize/1024/1024/1024) " GB"  vbcrlf _

"文件系统：" d.FileSystem vbcrlf _

"驱动器类型：" d.DriveType vbcrlf _

"是否就绪：" d.IsReady vbcrlf _

"路径：" d.Path vbcrlf _

"根目录：" d.RootFolder vbcrlf _

"序列号：" d.SerialNumber vbcrlf _

"共享名：" d.ShareName vbcrlf _

"卷名：" d.VolumeName vbcrlf vbcrlf

End If

Next

msgbox tmpstr

vb.net 显示版本

这个你把1.0.2.3这个字符串处理下就可以了。

这个属于字符串的处理
