vb.net源代码如何生成exe格式

vb.net编译出来的exe只有依赖.net

framework才能运行

但有一些第三方工具可以用来把exe用到的assembly和dll打包成一个exe文件，不过这样的结果就是exe体积非常大

比如.netz工具，它的官方地址：

使用很简单，比如你的exe文件是a.exe，直接netz

a.exe就可以把a和它用到的.net代码一起打包成一个exe

如何用vb.net获得网页的源代码

Dim url As String=" 网址"

Dim httpReq As System.Net.HttpWebRequest

Dim httpResp As System.Net.HttpWebResponse

Dim httpURL As New System.Uri(url)

httpReq = CType(WebRequest.Create(httpURL), HttpWebRequest)

httpReq.Method = "GET"

httpResp = CType(httpReq.GetResponse(), HttpWebResponse)

httpReq.KeepAlive = False ' 获取或设置一个值，该值指示是否与

Internet资源建立持久连接。

Dim reader As StreamReader = _

New StreamReader(httpResp.GetResponseStream,

System.Text.Encoding.GetEncoding(-0))

Dim respHTML As String = reader.ReadToEnd() 'respHTML就是网页源代码

请问为什么我公司的vb.net源码到了我的电脑上运行就会显示好多未声明啊？

用API 函数GetVolumeInformation得到的不是硬盘的序列号！！！

BOOL GetVolumeInformation(

LPCTSTR lpRootPathName,

LPTSTR lpVolumeNameBuffer,

DWORD nVolumeNameSize,

LPDWORD lpVolumeSerialNumber,

LPDWORD lpMaximumComponentLength,

LPDWORD lpFileSystemFlags,

LPTSTR lpFileSystemNameBuffer,

DWORD nFileSystemNameSize

);

看看英文啊：VolumeSerialNumber!得到的只是卷区序列号！

硬盘的序列号应该是

Drive Model Number________________: WDC WD400EB-00CPF0

Drive Serial Number_______________: WD-WCAATF083586

Drive Controller Revision Number__: 06.04G06

Controller Buffer Size on Drive___: 2097152 bytes

Drive Type________________________: Fixed

Drive Size________________________: 40020664320 bytes

中：

Drive Serial Number_______________: WD-WCAATF083586 这才是硬盘Serial Number！！！！

这个号是不会因为你格式化硬盘而改动，也不是网上流传的修改工具能改的，（其实网上流传的修改工具的也不过是卷区号而已！）

建议用 DiskID.dll或DiskID32.dll来获取

用diskid.dll和disk32.dll获得硬盘序列号

1.调用diskid.dll实现：

Option Explicit

Private Declare Function IsWinNT Lib "DiskID.DLL" () As Long

Private Declare Function ReadPhysicalDrive9X Lib "DiskID.DLL" (driveID As Long, buffer As Long, bufLen As Long) As Long

Private Declare Function ReadPhysicalDriveInNT Lib "DiskID.DLL" (driveID As Long, buffer As Long, bufLen As Long) As Long

Private Type DRIVER_INFO_OK

ModalNumber(39) As Byte

SerialNumber(19) As Byte

ControlNum(7) As Byte

DriveType As Long

Cylinders As Long

Heads As Long

Sectors As Long

End Type

Private Sub Command1_Click()

Dim x As DRIVER_INFO_OK

Dim i As Long

If IsWinNT = 1 Then

i = ReadPhysicalDriveInNT(ByVal 0, ByVal VarPtr(x), ByVal 256)

Else

i = ReadPhysicalDrive9X(ByVal 0, ByVal VarPtr(x), ByVal 256)

End If

Dim s As String

s = StrConv(x.ModalNumber, vbUnicode)

s = Left(s, InStr(1, s, Chr(0)) - 1)

MsgBox "硬件厂商代码为：" + s

s = StrConv(x.SerialNumber, vbUnicode)

s = Left(s, InStr(1, s, Chr(0)) - 1)

MsgBox "硬盘序列号为：" + s

End Sub

2.调用diskid32.dll实现：

Option Explicit

Private Declare Function DiskID32 Lib "DiskID32.DLL" (ByRef DiskModel As Byte, ByRef DiskID As Byte) As Long

Private Sub Command1_Click()

Dim DiskModel(31) As Byte, DiskID(31) As Byte, i As Integer, Model As String, ID As String

If DiskID32(DiskModel(0), DiskID(0)) 1 Then

MsgBox "get diskid32 err"

Exit Sub

End If

For i = 0 To 31

If Chr(DiskModel(i)) Chr(0) Then

Model = Model Chr(DiskModel(i))

End If

If Chr(DiskID(i)) Chr(0) Then

ID = ID Chr(DiskID(i))

End If

Next

MsgBox "硬件产生代码为：" + Model

MsgBox "硬盘序列号为：" + ID

End Sub

说明：diskid.dll可从下载

diskid32.dll可从下载
