Dim url As String = "http://task.zbj.com/t-rjkf/?t=5"

Dim web As new System.Windows.Forms.WebBrowser

web.ScriptErrorsSuppressed = True

web.Navigate(url)

Do While web.ReadyState <> 4

Application.DoEvents

Loop

Dim biaoti As String

Dim neirong As String

Dim trs = web.Document.GetElementsByTagName("table")(0).GetElementsByTagName("tr")

For j As Integer = 1 To trs.count - 1

Dim tr = trs(j)

Dim tds = tr.GetElementsByTagName("td")(0).GetElementsByTagName("p")

Dim tds1 = tr.GetElementsByTagName("td")(0).GetElementsByTagName("p")(0).GetElementsByTagName("a")

biaoti = tds1(0).innerhtml

neirong = tds(1).innerhtml

Dim dr111 As DataRow = DataTables("猪八戒").Find("标题 = '" & biaoti & "' and 内容 = '" & neirong & "'")

If dr111 IsNot Nothing Then '如果找到的话

Else

Tables("猪八戒").AddNew()

Tables("猪八戒").Current("录入时间") = Date.Today()

Tables("猪八戒").Current("标题") = biaoti

Tables("猪八戒").Current("内容") = neirong

Tables("猪八戒").Current("信息状态") = "未发送"

End If

DataTables("猪八戒").Save()

Dim drs As List(Of DataRow)

Dim txt As String = ""

drs = DataTables("猪八戒").Select("[信息状态] = '未发送'")

For Each dr As DataRow In drs

dr("信息状态") = "已发送"

biaoti = dr("标题")

biaoti = biaoti.Replace("+","").Replace("^","").Replace("%","").Replace("~","").Replace("(","").Replace(")","").Replace("[","").Replace("]","")

DataTables("猪八戒").Save()

If txt <> "" Then
