VBA挂在ie.busy和的readyState检查

扫码查看
本文介绍了VBA挂在ie.busy和的readyState检查的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我想从网站抓住一些足球运动员的数据，以填补私人使用的数据库。我已经包括下面的整个code。这第一个部分是一个活套调用第二个函数来填充数据库。我碰到这个code在MSACCESS填补数据库，去年夏天和它的工作太棒了。

现在，我只得到了几支球队，以填补前的节目被挂起来的

 虽然IE.Busy或者IE.ReadyState＆LT;＆GT; READYSTATE_COMPLETE：调用DoEvents：WEND

我搜索关于此错误无数的网站，并试图通过将在子功能等待一段秒或其他变通改变这个code。这些都不解决问题。我也试着在多台计算机上运行这一点。

第一台计算机通过3支球队（或第二功能的三个调用）做到了。第二慢的电脑使得它到5支球队。双方最终挂起。的第一计算机具有的Internet Explorer 10和第二有IE8。

在 Parse_Team_RawSalaries ，而不是使用 InternetExplorer.Application 对象，如何使用 MSXML2.XMLHTTP60 ？

因此​​，而不是这样的：

 设置IE =的CreateObject（InternetExplorer.Application）
IE.Visible = FALSE
IE.navigatehttp://www.rotoworld.com/teams/contracts/nfl/与＆amp;球队
虽然IE.Busy或者IE.ReadyState＆LT;＆GT; READYSTATE_COMPLETE：调用DoEvents：WEND
设置HTMLDOC = IE.Document

也许尝试使用这个（添加一个引用到VBA编辑器中的Microsoft XML 6.0在前）：

 昏暗的IE浏览器作为MSXML2.XMLHTTP60
设置IE =新MSXML2.XMLHTTP60

IE.OpenGET，http://www.rotoworld.com/teams/contracts/nfl/＆放大器;团队，假
IE.send

虽然IE.ReadyState＆LT;＆GT; 4
    的DoEvents
蜿蜒

昏暗HTMLDOC作为MSHTML.HTMLDocument
昏暗HTMLBody作为MSHTML.htmlBody

设置HTMLDOC =新MSHTML.HTMLDocument
设置HTMLBody = HTMLDoc.body
HTMLBody.innerHTML = IE.responseText

我通常发现， MSXML2.XMLHTTP60 （和 WinHttp.WinHtt prequest ，该物）通常表现得更好（更快，更可靠），比 InternetExplorer.Application 。

I am trying to grab some football player data from a website to fill a privately used database. I've included the entire code below. This first section is a looper that calls the second function to fill a database. I've run this code in MSAccess to fill a database last summer and it worked great.

Now I am only getting a few teams to fill before the program gets hung up at 

      While IE.Busy Or IE.ReadyState <> READYSTATE_COMPLETE: DoEvents: Wend

I've searched countless websites regarding this error and tried changing this code by putting in sub function to wait a period of seconds or other work arounds. None of those solve the issue. I've also tried running this on multiple computers.

The first computer made it through 3 teams (or three calls of the 2nd function). The second slower computer makes it through 5 teams. Both eventually hang. The 1st computer has Internet Explorer 10 and the second has IE8. 

Sub Parse_NFL_RawSalaries()

    Status ("Importing NFL Salary Information.")
    Dim mydb As Database
    Dim teamdata As DAO.Recordset
    Dim i As Integer
    Dim j As Double

    Set mydb = CurrentDb()
    Set teamdata = mydb.OpenRecordset("TEAM")

    i = 1
    With teamdata
        Do Until .EOF
            Call Parse_Team_RawSalaries(teamdata![RotoworldTeam])
            .MoveNext
            i = i + 1
            j = i / 32
           Status ("Importing NFL Salary Information. " & Str(Round(j * 100, 0)) & "% done")
        Loop
   End With

  ' reset variables
  teamdata.Close
  Set teamdata = Nothing
  Set mydb = Nothing

  Status ("")                  'resets the status bar

End Sub

Seconnd function:

Function Parse_Team_RawSalaries(Team As String)

    Dim mydb As Database

    Dim IE As InternetExplorer

   Set IE = CreateObject("InternetExplorer.Application")

   Set TABLEelements = HTMLdoc.getElementsByTagName("Table")
   For Each TABLEelement In TABLEelements
       If TABLEelement.id = "cp1_tblContracts" Then
            Set TRelements = TABLEelement.getElementsByTagName("TR")

                            Case 1
                                rst![position] = Trim(TDelement.innerText)
                            Case 2
                                rst![ContractTerms] = Trim(TDelement.innerText)
                        End Select
                        c = c + 1
                    Next TDelement
                    rst.Update
              End If
          Next TRelement
      End If
  Next TABLEelement
  ' reset variables
  rst.Close
  Set rst = Nothing
  Set mydb = Nothing

  IE.Quit


End Function
解决方案

In Parse_Team_RawSalaries, instead of using the InternetExplorer.Application object, how about using MSXML2.XMLHTTP60?

So, instead of this:

Set IE = CreateObject("InternetExplorer.Application")
IE.Visible = False
IE.navigate "http://www.rotoworld.com/teams/contracts/nfl/" & Team
While IE.Busy Or IE.ReadyState <> READYSTATE_COMPLETE: DoEvents: Wend
Set HTMLdoc = IE.Document

Maybe try using this (add a reference to "Microsoft XML 6.0" in VBA Editor first):

Dim IE As MSXML2.XMLHTTP60
Set IE = New MSXML2.XMLHTTP60

IE.Open "GET", "http://www.rotoworld.com/teams/contracts/nfl/" & Team, False
IE.send

While IE.ReadyState <> 4
    DoEvents
Wend

Dim HTMLDoc As MSHTML.HTMLDocument
Dim HTMLBody As MSHTML.htmlBody

Set HTMLDoc = New MSHTML.HTMLDocument
Set HTMLBody = HTMLDoc.body
HTMLBody.innerHTML = IE.responseText

I've generally found that MSXML2.XMLHTTP60 (and WinHttp.WinHttpRequest, for that matter) generally perform better (faster and more reliable) than InternetExplorer.Application.

这篇关于VBA挂在ie.busy和的readyState检查的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
