vb.net营销软件源码 vb源代码合集

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vb.net营销软件源码：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vb.net营销软件源码你格式化硬盘而改动vb.net营销软件源码，也不是网上流传的修改工具能改的vb.net营销软件源码，（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

VB程序源码如何使用

你需要安装vb6.0开发软件

如果安装了，就可以直接打开源码测试了，后缀名是vbp，（就是vb的工程文件）

如果没有安装vb6.0，还想打开源码看程序，那就右击 用记事本 打开后缀名为frm的文件，他是vb的窗口文件，源码都在他里面

一般得源码是没有生成exe可执行文件的，那样文件太多，太大，浪费空间

如果你自己想生成exe可执行文件，那就vb6.0得文件菜单中把文件保存成exe可执行文件就可以了，非常简单

好运！

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

求vb.net的源代码，最好说明其解决问题，越多越好，满意加50分。

下面这段代码vb.net营销软件源码，是vb.net营销软件源码我用来计算每个月存500元进银行，连续30年，最后连本带利能有多少钱。这里面涉及复利计算。界面中右边的文本框用来输出每一次计算的结果。

  Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

      Dim nianxian As Integer '年限变量

      Dim dingcun As Integer '定存变量

      Dim fuli_big As Long '大复利

      Dim fuli_small As Long '小复利

      Dim i As Integer '循环变量

      Dim DATAstring As String '数据字符串

      nianxian = Val(年限_TextBox.Text)

      dingcun = Val(定存_TextBox.Text)

      DATAstring = ""

      For i = 1 To nianxian

          fuli_small = dingcun * (1 + 0.1875)

          dingcun = fuli_small

          fuli_big = fuli_big + fuli_small

          DATAstring = DATAstring + "[" + Trim(Str(i)) + "]" + Str(fuli_big) + Chr(13) + Chr(10)

          'DATAstring = DATAstring + "[" + Trim(Str(i)) + "]" + Str(fuli_small) + Chr(13) + Chr(10)

      Next

      'fuli_big = fuli_small

      TextBox1.Text = DATAstring

      结果_TextBox.Text = Str(fuli_big) + "元"

  End Sub

vb.net中如何利用api函数获取网页源代码？？？

Dim MyClient As WebClient = New WebClient

Dim MyReader As New System.IO.StreamReader(MyClient.OpenRead(url), System.Text.Encoding.Default) '定义新vb.net营销软件源码的文件流并读取网页文件数据vb.net营销软件源码，url表示需要打开vb.net营销软件源码的网页地址

Dim longTxt As String = MyReader.ReadToEnd 'longtxt存储vb.net营销软件源码了网页的源码

MyReader.Close()
