VB程序源碼如何使用

你需要安裝vb6.0開發(fā)軟件

如果安裝了，就可以直接打開源碼測試了，后綴名是vbp，（就是vb的工程文件）

如果沒有安裝vb6.0，還想打開源碼看程序，那就右擊 用記事本 打開后綴名為frm的文件，他是vb的窗口文件，源碼都在他里面

一般得源碼是沒有生成exe可執(zhí)行文件的，那樣文件太多，太大，浪費(fèi)空間

如果你自己想生成exe可執(zhí)行文件，那就vb6.0得文件菜單中把文件保存成exe可執(zhí)行文件就可以了，非常簡單

好運(yùn)！

如何用vb.net獲取網(wǎng)頁源代碼

使用webbrowser控件來加載網(wǎng)頁，然后再

Private

Sub

WebBrowser

1_DocumentCompleted下通過使用WebBrowser1.Document.Body.

InnerHtml

來獲取網(wǎng)頁的源代碼，或使用

WebBrowser1.Document.Body.InnerText來獲取網(wǎng)頁中的文本。之后可以通過字符串控制指令或者

正則表達(dá)式

來精確獲取到你所需的數(shù)據(jù)。

誰有vb.net+sqlserver開發(fā)的《庫存管理系統(tǒng)》的源碼和源文件？？

1.顯示直觀，點(diǎn)擊“名稱”中的“加號”展開下拉菜單，顯示裝備的詳細(xì)情況和維修情況，簡潔清楚；

2.更為實(shí)用的搜索功能；

3.數(shù)據(jù)庫防遠(yuǎn)程下載；

4.后臺操作簡簡潔，信息錄入非常方便；

5.管理員分為三個(gè)等級；

6.出于好玩，添加了萬年歷、手機(jī)號碼查詢、郵編查詢功能；

7.所有在系統(tǒng)中使用到的廣告圖片的源文件（png格式，fireworks制作）均保存于（fire文件夾中）。

vb.NET webbrowser 修改網(wǎng)頁源碼

Dim c

Private Sub Form_Load()

URL = ""

c = 0

WebBrowser1.Navigate URL

End Sub

Private Sub WebBrowser1_DocumentComplete(ByVal pDisp As Object, URL As Variant)

If c = 1 Then Exit Sub '這個(gè)是為了防止這個(gè)過程無限執(zhí)行下去

c = c + 1

tmp = WebBrowser1.Document.body.innerhtml

tmp = Replace(tmp, "88753967", "好玩嗎？")

WebBrowser1.Document.body.innerhtml = tmp

End Sub

如何用vb.net獲得網(wǎng)頁的源代碼

Dim url As String=" 網(wǎng)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 ' 獲取或設(shè)置一個(gè)值，該值指示是否與

Internet資源建立持久連接。

Dim reader As StreamReader = _

New StreamReader(httpResp.GetResponseStream,

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

Dim respHTML As String = reader.ReadToEnd() 'respHTML就是網(wǎng)頁源代碼
