关于论坛上一些关于表单的帖子我看了许多，自己试验了一下，如下：
Private Sub Form_Load()
WebBrowser1.Navigate "http://192.168.0.8/login1.jsp"
End Sub
Private Sub WebBrowser1_DocumentComplete(ByVal pDisp As Object, URL As Variant)
Dim doc As IHTMLDocument2
Set doc = WebBrowser1.Document
doc.All.Item("USER").Value = "ncutqi"
doc.All.Item("PASSWORD").Value = "123456"
End Sub完成后运行，在WebBrowser控件上已经看到用户名与密码已经自动填入，现在想问两个问题：
1.怎样让它自动登录？即回车？我执行setkey没有效果
2.登录完成后发现提示错误：实时错误‘91’，对象变量或with块变量未设置。希望大家能给一个解决方法，谢谢：）
