1.如何用vb得到网页的界面源代码
2.VB登陆窗体代码。数据库呢是源码源码用access的 数据库名为data 有一个登陆表 有两个字段名 用户名 密码
如何用vb得到网页的源代码
1 先加载网页:
Private Sub Form_Load()
WebBrowser1.Navigate "/question/.html"
End Sub
2 加载完成后取字符串到文本框:
Private Sub WebBrowser1_DocumentComplete(ByVal pDisp As Object, URL As Variant)
Dim doc As Object, objhtml As Object
Dim strhtml As String
On Error GoTo errorsub
Me.Caption = WebBrowser1.LocationName & " 加载完成"
If MaxWebNum <= 0 Then
Set doc = WebBrowser1.Document
Set objhtml = doc.body.createtextrange()
If Not IsNull(objhtml) Then
strhtml = WebBrowser1.Document.body.innertext
Text1.Text = strhtml
End If
End If
Exit Sub
errorsub:
Text1.Text = "错误!!界面小程序源码大全!源码源码用"
End Sub
VB登陆窗体代码。界面源码基础上增加一些卷积层数据库呢是源码源码用抖音自动转发二维码源码access的 数据库名为data 有一个登陆表 有两个字段名 用户名 密码
新建vb工程,然后点击“工程”-->“引用”,界面在以下两个选项前挑勾:Microsoft Data Environment Instance 1.0
Microsoft ActiveX Objects 2.5 Library
因为你要用Access数据库,源码源码用所以需要在工程中添加控件。界面
建立Access数据库,源码源码用在这个vb工程文件夹新建一个文件夹,界面命名为table,源码源码用然后将这个Access数据库文件放入table文件夹中。界面反波胆足球赛事平台源码
源代码:
Private Con_Access As Connections
Private Sub Form_Load()
Set Con_Access = New Connection
With Con_Access
.Provider = "microsoft.jet.oledb.4.0"
.ConnectionString = App.Path & "\table\ship.mdb"
.Open
End With
End Sub
Private Sub cmdOK_Click()
Dim cmd As New Command
Dim rd As New Recordset
cmd.ActiveConnection = Con_Access
cmd.CommandText = "select username,源码源码用userpassword from usertable where username='" & Text1.Text & "'"
On Error GoTo db_error
Set rd = cmd.Execute
On Error GoTo 0
If rd.EOF Then
MsgBox "用户名不存在。",界面传奇第二大陆源码 vbOKOnly + vbInformation, "错误"
Exit Sub
End If
db_error:
MsgBox Err.Description, vbOKOnly + vbInformation, "错误"
End Sub
Private Sub cmdCancel_Click()
End
End Sub
