所以我被赋予了在我为网站工作的公司中创建新用户的任务。我获得了100多个用户名和电子邮件地址的excel表。我不想手动执行它所以决定尝试编写程序。我以前从未接触过VB，这是我能够达到的目标。它适用于第一次运行while循环，但后来收到错误：
运行时错误'91' 对象变量或未设置块变量
当我尝试调试此错误时，我的代码中的这一行会突出显示：
IE.document.GetElementsbyname("user_login")(0).Value = ThisWorkbook.Sheets("sheet1").Cells(j, i) ' sets login info
在我的Excel电子表格中，电子邮件地址与登录信息相同，它们是通过outlook发送电子邮件的链接。我会看看这是否会导致我的错误，但与此同时，我希望得到第二双眼睛。谢谢您阅读此篇。这是我在这里发表的第一篇文章，所以如果不像你想要的那样提供信息，我会道歉
到目前为止，这是我的其余代码
Sub FillInternetForm()
Dim IE As Object
Set IE = CreateObject("InternetExplorer.Application")
'create new instance of IE
Dim i As Integer
Dim j As Integer
Dim x As Integer
Dim y As Integer
Dim s As String
s = "paswd" ' pasword setting
i = 4 ' column D for email input
j = 50 ' row to start
x = 9 ' column I For last name input
y = 10 'column j for last name
'you want to use open IE window. Easiest way I know of is via title bar.
While j < 121
Wait
IE.Navigate "website link"
'go to web page listed inside quotes
IE.Visible = True
While IE.busy
DoEvents 'wait until IE is done loading page.
Wend
IE.document.GetElementsbyname("user_login")(0).Value = ThisWorkbook.Sheets("sheet1").Cells(j, i) ' sets login info
IE.document.GetElementsbyname("email")(0).Value = ThisWorkbook.Sheets("sheet1").Cells(j, i) ' sets email address
IE.document.GetElementsbyname("first_name")(0).Value = ThisWorkbook.Sheets("sheet1").Cells(j, y) ' sets first name
IE.document.GetElementsbyname("last_name")(0).Value = ThisWorkbook.Sheets("sheet1").Cells(j, x) ' sets last name
Set elementcol = IE.document.getElementsByClassName("button button-secondary wp-generate-pw hide-if-no-js")
elementcol.Item(0).Click 'shows the password
While IE.busy
DoEvents 'wait until IE is done loading page.
Wend
IE.document.GetElementsbyname("pass1-text")(0).Value = s 'sets the password
Wait
Set elementcol = IE.document.getElementsByClassName("pw-checkbox")
elementcol.Item(0).Click ' clicks confirmation of weak password choice
While IE.busy
DoEvents 'wait until IE is done loading page.
Wend
Set elementcol = IE.document.GetElementsbyname("send_user_notification")
elementcol.Item(0).Click ' unclicks send new user email
While IE.busy
DoEvents 'wait until IE is done loading page.
Wend
IE.document.getElementByID("createusersub").Click ' clicks add new user
While IE.busy
DoEvents 'wait until IE is done loading page.
Wend
j = j + 1
While IE.busy
DoEvents 'wait until IE is done loading page.
Wend
Wend
End Sub
Sub Wait()
Application.Wait Time + TimeSerial(0, 0, 5)
End Sub
编辑：只有在我的循环中运行5次后才出现此错误
答案 0 :(得分：0)
缓存可能已从所有循环中阻塞。
